   The neck height of the neck flange is low, which can improve the rigidity and load-bearing caσpacity of the flange. Compared with the butt-welded flange, the welding workload is large, the el×ectrode consumption is high, and it cannot withstand high temper$ature and high pressure, repeated bending and temper‍ature fluctuations, but the on-site device is more convenient, and the process o★f welding seam scratching can be omitted, which is more popular. Butt welding flange ♠with neck: neck flange welding is usually called "high hub" flange. Its purpose is to tr™ansfer the pressure of the pipeline, thereby reducing the high stress concentration≈ in the flange base. Neck flange welding is a good desiσgn for butt welding those flanges that are provided due to th↔eir own constructive value. However, the price is relatively high because of the λcomplicated production process of the product. Threaded (threaded) ↑flange: The threaded flange is connected by threaded fasteners. But the center of the product ±has a thread size corresponding to the pipe. Its mai¶n advantage is that it can be assembled without welding. Sliding flange: S​liding flange has a lower hub, because the pipe enters the single flange befo★re welding. This is to provide sufficient strength inside and outside the wel↓ding to avoid leakage. Sliding flanges are matched with boring pipes with slightly larger outer± diameters. They are better than neck flange welding due to lower initial cost. flange Ma♣ny users, but the cost of the latter device will not be low, due to the increase in the number of wλeld neck flanges, lap flange: in practice, the lap fl$ange is the same complete sliding flange, unless it is in the hole and A radius betw een flange races. It is necessary for the radius to have the flange to contai≠n the lap stub to complete. Usually, the lap flange and the lap stu¥b end mating together will assemble the system. The socket wel>ding flange is a similar sliding flange, unless it has a hole and a counter hole size. Th e matching of the counter hole and the pipe allows the pipe to be in​serted into a sliding flange similar to the flange. The diameter of the smaller hole is ma¶tched with the same pipe with the same ID. The restriction is a built-in $hole that stays at the bottom as a shoulder sleeve designed for pipes. This eφliminates any flow restrictions when using socket welding flan✘ges.
  1. In order to compact the sealing surface of the flat welding flange, only a small pres₩sure is required. As the required pressure drops, the si ze of the bolts and the number required are correspondingly r↔educed. After all, a plan is planned. A flat welding flangσe product with a relatively small volume and a relatively light weight. ←    2. The production of flat welded flanges can save data and re'duce costs. When the raw material of the pipe is special© and the price is high, the cost of welding the flange of the same raw' material will be high, and the use of this flange can effectively save the cost of m✘aterials. Conducive to construction, when connecting, the bolt holes of t÷he flange are inconvenient to align or to avoid replacing the fla∞nge bolt holes of the equipment, etc., the use of this flat weldΩed flange is very suitable.         3. The flat welding flange can save space and redu♥ce weight in the process of use. The most important thing is to ensure that ₩the head part will not leak. It has a very outstanding se≥aling function. The reason why the size of the compact flan∞ge is reduced is because The diameter of the seal is reduced, whichΩ will reduce the cross-section of the sealing surface. Also, the flange gasket has now' been replaced by a sealing ring to ensure an outstanding mat§ching of the flat welded flange seal facing the sea₹ling surface.    flat welding flange    But it also has some disadvantages:   ₽ Disadvantages of flat welding flange:   The main design disadvantage of flat welded flanges i↓s that it cannot ensure no leakage. This is the lack of its planning: the 'connection is dynamic, and for example, thermal expansion and fluct uating cyclic loads will cause movement between the flangεe surfaces, which will affect the function of the flange, which will damage t&he integrity of the flange and eventually lead to leakage. It is✔ impossible for any product to be without shortcoming​s, just try to control the lack of products to the minim‍um, so the company tries to perfect the functions of the products when p​roducing flat welded flanges to make them play the greateεst role.
      Flange work characteristics:   Flange work characteristics:    1. A self-controγl butterfly valve that can be remotely controlled, which also h¥as the characteristics of a flanged butterfly valve, and can be eqΩuipped with a wide range of butterfly valves;   2. The power supply is the drφiving energy of the butterfly valve, with a wide rangeφ of power sources, wide application range, saving human resources, and having work efficiency;↑   3. Convenient operation and easy to meet various control requirements. It can¥ be realized by selecting different actuators, signal feedback, flow adjustment, ex↑plosion-proof and other functions;   4. Ultra-miniaturization c an be realized, mechanical self-locking can be realized, and differen♥t sealing rings can be changed to meet different working c​onditions.   The working principle of flange:   Using the actuator to iπnput a standard signal of 0-10 mA, the motor group drives the gear, worm,♣ and torque to drive the disc to rotate. When the valve is in the fully open position, the thickn↕ess of the butterfly plate is the resistance of the medium flowing through the valve bod y, so the pressure drop generated by the valve is small, so it has better flow control characβteristics.   Butterfly valve has two sealing types: elastic seal and metal seal. For elastic seali ng valves, the sealing ring can be embedded on the valve body or attached to the perip¥hery of the butterfly plate. The valve with metal sea✔l generally has a longer life than the valve with elastic seal, but it is difficult to achi★eve a complete seal. Metal seals can adapt to higher operating temperatures, while elastic seals ha¶ve the defect of temperature limitation. If flanged butterf>ly valves are required to be used as flow control, the mai↑n thing is to correctly select the size and type of the valve.
 The valve is an accessory of the pipeline, used to control the flow, pressure, anφd direction of the fluid. The fluid to be controlled can be liquid, gas, ga‌s-liquid mixture or solid-liquid mixture.   one. Basic parameters of valve   The basic paramete rs of the valve include working pressure (PN), working temperature (T) and​ nominal diameter (DN). For various valves equipped on pipelines, nominal✘ pressure and nominal diameter are commonly used as basic parameters✘. Nominal pressure refers to the maximum working pressure that a valve of a certain material 'can withstand at a specified temperature. The nominal diameter refers to the nominal inner di♥ameter of the connecting end of the valve body and the pip↑eline. Valves, pipelines and pipeline accessories of the same nomina→l diameter can be connected to each other, which is interchangeabl∞e.   two. Valve classification    1. According to function and purpos₽e    According to the different functions of the valve, it can be divide♦d into the following five types:   ①Shutoff valve"    shut-off valve is also called closed-circuit valve, its function i↑s to connect or cut off the medium in the pipeline. Block valves include gate valves, globe ÷valves, plug valves, ball valves, butterfly valves,✘ and diaphragm valves.   ②Check valve    Check valve i₹s also called one-way valve or check valve, its function is to prev±ent the back flow of the medium in the pipeline. For♦ example, the suction valve of the water pump belongs to the n'on-return valve category.   ③Safety valve    The role of safety valves is to p♦revent the pressure of the medium in the pipeline or device from exceedin<g the specified value to protect the safe operation of ©subsequent equipment.   ④Regulating valve   The function of the 'regulating valve is to regulate the pressure, flow and other parameters of the medium. The regulati♦ng valve has different classification methods. According‌ to the purpose and function, the regulating valve can be divided into: ©   (1) Two-position valve. The two-position valve is mainly used to cl©ose or connect the medium.    (2) Regulating valve. The regulating valve is mainly used fo♠r regulating the coefficient. When selecting the valve, the fl±ow characteristics of the regulating valve need to be determined; the regulating valve can φbe divided into the following forms according to the★ structure: single-seat regulating valve; double-seat regulating valve; sleeve regulating va♥lve; angle regulating Valve; three-way regulating valve; diaphragm valve; butterfly valve; ball v≠alve; eccentric rotary valve.    (3) Shut-off valve. Usually refers to a valve wγith a leakage rate of less than one part in 100,000.   ⑤Divert valve    The d₹iverter valve includes various distribution valves and flow valves,  etc., whose function is to distribute, separate or mix the medium in the pipeline.   2. Accordin×g to the valve drive mode   According to the valve drive mode, it can be divided into the follow×ing three types:   ①Automatic valve    refers to valves that do not require external drive, ☆but rely on the energy of the medium to actuate the valve, such as safety valves, pres£sure reducing valves, traps, check valves, automatic control valves, etc.   ②PowΩer driven valve   The power-driven valve can be driven by variousγ power sources. Including electric valves driven by electricity, pneuma>tic valves driven by compressed air, hydraulic valves driven by hydraulic pressure such as oil, an d combinations of various driving methods, such as pneumatic-electric valves. ©  ③Manual valve   Manual valves use handwheels, handles, levers, sprockets and other cπomponents to manipulate the valve action by manpower. When theε valve closing torque is large, a gear or turbo reducer can be set between the handwheel and the ∞valve stem. If necessary, universal joints and drive shaft™s can also be used for long-distance operation.   3. Prφess the connection method    can be divided into the following six type s according to the connection method:   ①Threaded connection valve: γThe valve body has an internal thread or an external thread to connect with the pipe thread;    ②Flange connection valve: the valve body has a flange to♥ connect with the pipeline flange;   ③Welding connection₹ valve: The valve body has a welding groove and is w€elded to the pipeline;   ④Clamp-connected valve: the valve body has a clamp to conn≠ect with the pipe clamp;   ⑤ Card sleeve connection valve:• It is connected with the pipeline by a card sleeve;   ⑥Wafer connection valv™e: a connection form in which the valve and the two pipes are directly clampe★d together with bolts.   4. According to the valve body material   ①Metal₹ material valve   The valve body and other parts are mad≈e of metal materials, such as cast iron valves, carbon steel valves, alloy steel ∑valves, copper alloy valves, aluminum alloy valves, lead alloy valves, titanium alloy valves, Monel• alloy valves, etc.   ②Non-metallic valve   The valve body and other part₩s are m
The caliper can also be called a brake cylinder. There are a lot of pistons inside the caliper★. The function of the caliper is to push the brake pads to clamp the ÷brake disc, so that the car can slow down. After the brake pads clamp the brakeπ disc, the kinetic energy can be converted into heat energy.★ The brake system is a vital system in a car. The brake system is related to the driving stability ®and driving safety factor of the car. The key components of >the brake system include vacuum booster pump, brake master cylinder, br®ake cylinder, brake pads, and brake discs. Brake pads and brake discs are basically wear∏ing parts that need to be replaced on a regular basis. As the driving distance of the c♦ar increases, the brake pads and brake discs will ba∑sically continue to wear. After the brake pads and brake disc€s are worn to a certain degree, they need to be repla®ced. If they are not replaced, the braking distance will be affected. After the driver steps o®n the brake pedal, the master cylinder can push the brake cylinder  through the brake fluid. At this time, the brake cylinder can push the brake pads to clamp the br÷ake disc. The vacuum booster pump provides power assistance, and the vacuum booster pum®p allows the driver to easily step on the brake pedal. The brake∞ fluid in the brake system needs to be replaced regularly. If it is not replaced for a lon∑g time, it will affect the braking force and braking distance. Brake fluid is a kind of flβuid that is easier to absorb water. When the water content of the brake fluid reaches 3%, it needs$ to be replaced. After replacing the brake fluid, the air in the br&ake system pipeline needs to be emptied, otherwise the braking force and br​aking distance may also be affected.
   We have seen many products using gears in our lives, but do you know  what principle they use gears? According to its working principle,    gear hasγ the following functions: First, gears can transmit mechanical power,  such as automobile gear shifting devices, industrial gearb∞oxes, etc.; second, gears can change the direction of movement, such as mechanφical watches, shaking head devices in electric fans, etc.; thir∏d, gears can reduce speed and Improve torque, such as motor reducer, vario×us speed change mechanisms, etc.   Gear transmission mechanism    Here are two interesting appli♠cations of gears in automobiles and aviation, let's take a look at the role £of gears in them.    There is a mechanical structure iδn a car called a differential, which is an extremely important part. When a car turns, the spe$eds of the inner and outer wheels are different. If there isε no differential, the speeds of the inner and outer< wheels are the same. The wheels slip and roll over. Moreover, the speed of the car is  very fast, and it is absolutely impossible to have no differσential at high speeds. The gear here is on the differential, which can not only transmit t¶he power of the engine, but also reduce the speed through the different☆ speed ratios of the gear device, and at the same time can achieve a very cool "differential" &function.    three-dimensional model of differential   In aviatioβn, helicopters using coaxial reversal technology are favored by ma✔ny countries because of their excellent performance. Th♦is helicopter has two propellers on the same shaft. When the pβlane is flying, the rotation direction of the two propellers must be opposit§e to ensure the power balance of the plane.   Helicopter using coaxial reΩversal technology    From the three-dimensional model of the coaxia"l reversal structure, it can be seen that after two transformations of the gear, the mechanical tra✘nsmission direction is smoothly changed, and two different rotation directions are realizedα on the same shaft.
