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.
控制閥的閥體型式很多，常用的有單閥座、雙閥座、角式、隔膜式、小流量、三通、偏心旋轉、蝶式、套筒式、球形等。在具體選型時，可作以下考慮:
1. 主要根據所選的流動特性、不平衡力等因素進行考慮。
2. 當流體介質是含有高濃度磨損顆粒的懸浮液時，閥門內部的材料應該是堅硬的。
3.由于介質具有腐蝕性，盡量選用簡單的閥門結構。
4. 當介質溫度、壓力和高變化時，應選用由溫度、壓力變化小的閥芯和閥座材料。
5. 閃光和空化只發生在液體介質中。在實際生產過程中，閃蒸和汽蝕會形成振動和噪聲，縮短閥門的使用壽命，因此應選用防止閃蒸和汽蝕的閥門。
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. 控制閥有各種類型，它們的應用是不同的。因此，應根據生產工藝的要求合理選擇控制閥的類型。
2. 氣動控制閥分為兩種類型:氣體開啟閥和氣體關閉閥。氣開控制閥在故障狀態下關閉，氣關控制閥在故障狀態下打開。一些輔助設備可以用來形成保護閥或使控制閥自鎖，即使控制閥保持故障后才能開啟。
3.通過正、反式執行機構和正、反閥組合，實現氣體的開啟和關閉方式。在使用閥門定位器時，也可以通過閥門定位器來實現。
4. 各種控制閥都有自己的特點，有不同的結構。
