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.

調(diào)節(jié)閥的閥體類型有很多，常用的通單座、通雙座、角座、隔膜、小流量、三通、偏心旋轉(zhuǎn)、蝶閥、套筒式、球面式等。在具體選型時可做以下考慮:

1. 主要是根據(jù)所選的流動特性、不平衡力等因素進行考慮。

2. 當流體介質(zhì)為含有高濃度磨損顆粒的懸浮液時，閥的內(nèi)部材料應(yīng)堅硬。

3.由于介質(zhì)具有腐蝕性，盡量選用簡單的閥門結(jié)構(gòu)。

4. 當介質(zhì)溫度、壓力變化較大時，應(yīng)選擇受溫度、壓力變化較小的閥芯和閥座材料。

5. 閃光和空化只發(fā)生在液體介質(zhì)中。在實際生產(chǎn)過程中，閃蒸和汽蝕都會形成振動和噪聲，縮短閥門的使用壽命，因此應(yīng)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. 控制閥的種類繁多，其應(yīng)用也各不相同。因此，控制閥的類型應(yīng)根據(jù)生產(chǎn)工藝的要求合理選擇。

2. 氣動調(diào)節(jié)閥分為氣開和氣關(guān)兩種。氣開控制閥在故障狀態(tài)關(guān)閉，氣閉控制閥在故障狀態(tài)打開。一些輔助設(shè)備可以用來形成保護閥或使控制閥自鎖，即控制閥在閥門開啟前保持故障。

3.通過正、反式執(zhí)行機構(gòu)的型式以及正、反閥體相結(jié)合的方式來實現(xiàn)開、關(guān)氣的方式。在使用閥門定位器時，也可以通過閥門定位器來實現(xiàn)。

4. 各種控制閥結(jié)構(gòu)不同，各有特點。
