調(diào)節(jié)閥的產(chǎn)品種類繁多，結(jié)構(gòu)多樣，還在不斷更新變化。一般來說，新疆閥門是通用的，可以與氣動執(zhí)行機構(gòu)、電動執(zhí)行機構(gòu)或其他執(zhí)行機構(gòu)相匹配。那么如何選擇這些各種調(diào)節(jié)閥呢？選擇調(diào)節(jié)閥的閥體類型是調(diào)節(jié)閥的選擇。重要環(huán)節(jié)，因此在具體選擇時，可以從以下幾個方面考慮：

There are a wide variety of products and structures for regulating valves, which are constantly being updated and changed. Generally speaking, Xinjiang valves are universal and can be matched with pneumatic actuators, electric actuators, or other actuators. So how do you choose these various regulating valves? Choosing the valve body type of the regulating valve is the choice of the regulating valve. Important links, therefore, when making specific choices, the following aspects can be considered:

閥芯的形狀結(jié)構(gòu)主要取決于所選流量特性和不平衡性等因素。

The shape and structure of the valve core mainly depend on factors such as the selected flow characteristics and imbalance.

耐腐蝕因介質(zhì)具有腐蝕性，在滿足調(diào)節(jié)功能的情況下，盡量選用結(jié)構(gòu)簡單的閥門。新疆閥門生產(chǎn)廠家說在介質(zhì)溫度、壓力高、變化大的情況下，應(yīng)選用閥芯和閥座材料進(jìn)行溫度、壓力變化小的閥門。

Due to the corrosiveness of the medium, it is recommended to choose valves with a simple structure while meeting the regulatory function. Valve manufacturers in Xinjiang say that when the medium temperature, pressure, and changes are high, valve cores and valve seat materials should be selected for valves with small temperature and pressure changes.

(4)當(dāng)流體介質(zhì)是含有高濃度磨損顆粒的懸浮液時，閥芯和閥座的接合面每次關(guān)閉都會受到嚴(yán)重摩擦。因此，閥門的流路應(yīng)光滑，閥門的內(nèi)部材料應(yīng)堅硬。

(4) When the fluid medium is a suspension containing high concentration of wear particles, the joint surface between the valve core and valve seat will experience severe friction every time it is closed. Therefore, the flow path of the valve should be smooth, and the internal material of the valve should be hard.

(5)液體介質(zhì)只能防止閃蒸和空化。在實際生產(chǎn)過程中，閃蒸和空化不僅影響流量系數(shù)的計算，還會產(chǎn)生振動和噪音，縮短閥門的使用壽命。因此，在選擇閥門時，應(yīng)防止閥門閃蒸和空化。

(5) Liquid media can only prevent flashing and cavitation. In the actual production process, flash evaporation and cavitation not only affect the calculation of flow coefficient, but also generate vibration and noise, shortening the service life of the valve. Therefore, when selecting valves, it is important to prevent valve flashing and cavitation.

從輸出力的角度考慮輸出力。

Consider the output force from the perspective of output force.

為了使調(diào)節(jié)閥正常工作，所使用的執(zhí)行機構(gòu)應(yīng)能夠產(chǎn)生足夠的輸出力來克服各種阻力，以確保高度密封和閥門打開。一般沒有復(fù)位彈簧用于氣動、液壓和電動執(zhí)行機構(gòu)的雙重功能。新疆閥門生產(chǎn)廠家說力的大小與其運行方向無關(guān)。因此，選擇執(zhí)行機構(gòu)的關(guān)鍵在于找出大輸出力和電機旋轉(zhuǎn)扭矩。對于單作用的氣動執(zhí)行機構(gòu)，輸出力與閥門的開度有關(guān)，調(diào)節(jié)閥上的力也會影響運動特性，因此需要在整個調(diào)節(jié)閥的開度范圍內(nèi)建立力平衡。

In order to ensure the normal operation of the regulating valve, the actuator used should be able to generate sufficient output force to overcome various resistances, ensuring high sealing and valve opening. Generally, there is no return spring used for the dual functions of pneumatic, hydraulic, and electric actuators. The valve manufacturer in Xinjiang stated that the magnitude of force is independent of its operating direction. Therefore, the key to selecting an actuator is to identify the large output force and motor rotational torque. For single acting pneumatic actuators, the output force is related to the opening of the valve, and the force on the regulating valve also affects the motion characteristics. Therefore, it is necessary to establish force balance within the entire opening range of the regulating valve.
