The body type of control valve is a lot of, commonly used through single seat, through double seat, Angle, diaphragm, small flow, tee, eccentric rotation, butterfly, sleeve type, spherical, etc.In the specific selection, the following considerations can be made:
1. It is mainly considered according to the selected flow characteristics, unbalanced forces and other factors.
2. When the fluid medium is a suspension containing a high concentration of wear particles, the internal material of the valve should be hard.
3. As the medium is corrosive, try to choose a simple valve structure.
4. When the medium temperature, pressure and high change, should choose the valve core and valve seat material by temperature, pressure change small valve.
5. Flash and cavitation occur only in liquid media.In the actual production process, flash and cavitation will form vibration and noise, shorten the service life of the valve, so the valve should be selected to prevent flash and cavitation.
控制阀的阀体型式很多，常用的有单阀座、双阀座、角式、隔膜式、小流量、三通、偏心旋转、蝶式、套筒式、球形等。在具体选型时，可作以下考虑:
1. 主要根据所选的流动特性、不平衡力等因素进行考虑。
2. 当流体介质是含有高浓度磨损颗粒的悬浮液时，阀门内部的材料应该是坚硬的。
3.由于介质具有腐蚀性，尽量选用简单的阀门结构。
4. 当介质温度、压力和高变化时，应选用由温度、压力变化小的阀芯和阀座材料。
5. 闪光和空化只发生在液体介质中。在实际生产过程中，闪蒸和汽蚀会形成振动和噪声，缩短阀门的使用寿命，因此应选用防止闪蒸和汽蚀的阀门。
1. There are various types of control valves, and their applications are different. Therefore, the type of control valve should be reasonably selected according to the requirements of the production process.
2. Pneumatic control valves are divided into two types: gas opening and gas closing.The gas-open control valve closes in the failure state, and the gas-close control valve opens in the failure state.Some auxiliary equipment can be used to form a protection valve or to make the control valve self-lock, that is, the control valve to maintain the failure before the valve opening.
3. The way of gas opening and gas closing can be achieved through the type of positive and reactive actuator and the combination of positive and anti-body valves. When using the valve positioner, it can also be achieved through the valve positioner.
4. Various control valves have their own characteristics with different structures.
1. 控制阀有各种类型，它们的应用是不同的。因此，应根据生产工艺的要求合理选择控制阀的类型。
2. 气动控制阀分为两种类型:气体开启阀和气体关闭阀。气开控制阀在故障状态下关闭，气关控制阀在故障状态下打开。一些辅助设备可以用来形成保护阀或使控制阀自锁，即使控制阀保持故障后才能开启。
3.通过正、反式执行机构和正、反阀组合，实现气体的开启和关闭方式。在使用阀门定位器时，也可以通过阀门定位器来实现。
4. 各种控制阀都有自己的特点，有不同的结构。
