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.

调节阀的阀体类型有很多，常用的通单座、通双座、角座、隔膜、小流量、三通、偏心旋转、蝶阀、套筒式、球面式等。在具体选型时可做以下考虑:

1. 主要是根据所选的流动特性、不平衡力等因素进行考虑。

2. 当流体介质为含有高浓度磨损颗粒的悬浮液时，阀的内部材料应坚硬。

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、压力变化较大时，应选择受温度、压力变化较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，闪蒸和汽蚀都会形成振动和噪声，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. 控制阀的种类繁多，其应用也各不相同。因此，控制阀的类型应根据生产工艺的要求合理选择。

2. 气动调节阀分为气开和气关两种。气开控制阀在故障状态关闭，气闭控制阀在故障状态打开。一些辅助设备可以用来形成保护阀或使控制阀自锁，即控制阀在阀门开启前保持故障。

3.通过正、反式执行机构的型式以及正、反阀体相结合的方式来实现开、关气的方式。在使用阀门定位器时，也可以通过阀门定位器来实现。

4. 各种控制阀结构不同，各有特点。
