良工閥門(mén)閥門(mén)其運(yùn)動(dòng)過(guò)程可以由行程、扭矩或軸向推力控制。由于執(zhí)行器的工作特性和利用率取決于管道或設(shè)備上良工閥門(mén)閥門(mén)的類(lèi)型、設(shè)備的工作規(guī)范和位置。所以，掌握?qǐng)?zhí)行機(jī)構(gòu)的正確選擇，考慮到防止過(guò)載(工作扭矩高于控制扭矩)的發(fā)生是至關(guān)重要的。操作力矩是選擇執(zhí)行器的主要參數(shù)。電氣設(shè)備的輸出力矩應(yīng)該是良工閥門(mén)閥門(mén)操作力矩的1.2~1.5倍。執(zhí)行器的主機(jī)結(jié)構(gòu)有兩種，一種是不配置推力板，此時(shí)直接輸出扭矩；另一種是配置推力板。此時(shí)，輸出扭矩通過(guò)推力板中的閥桿螺母轉(zhuǎn)換為輸出推力。
The movement process of Lianggong valve can be controlled by stroke, torque, or axial thrust. Due to the working characteristics and utilization rate of the actuator depending on the type of valve on the pipeline or equipment, the working specifications and position of the equipment. Therefore, it is crucial to master the correct selection of the actuator, taking into account the prevention of overload (working torque higher than control torque). The operating torque is the main parameter for selecting actuators. The output torque of electrical equipment should be 1.2~1.5 times the operating torque of Lianggong valve. There are two main structures for actuators: one is without a thrust plate, which directly outputs torque; Another option is to configure thrust plates. At this point, the output torque is converted into output thrust through the valve stem nut in the thrust plate.
執(zhí)行器輸出軸旋轉(zhuǎn)圈數(shù)與良工閥門(mén)閥門(mén)的公稱直徑、閥桿螺距、螺紋頭數(shù)有關(guān)，按M計(jì)算。=H/ZS計(jì)算(公式中：M為電動(dòng)設(shè)備應(yīng)滿足的總旋轉(zhuǎn)圈數(shù)；H為良工閥門(mén)閥門(mén)的開(kāi)啟高度，mm；S是閥桿傳動(dòng)螺
The number of rotations of the actuator output shaft is related to the nominal diameter, stem pitch, and number of thread heads of the Lianggong valve, and is calculated according to M= H/ZS calculation (in the formula: M is the total number of rotations that electric equipment should meet; H is the opening height of Lianggong valve, mm; S is the valve stem transmission screw)
紋的螺距，mm；Z為閥桿螺紋頭數(shù)。)對(duì)于多旋轉(zhuǎn)的明桿良工閥門(mén)閥門(mén)，如果執(zhí)行器允許通過(guò)的大閥桿直徑不能通過(guò)所配良工閥門(mén)閥門(mén)的閥桿，則不能組裝成電動(dòng)良工閥門(mén)閥門(mén)。因此，電氣設(shè)備中空輸出軸的內(nèi)徑必須大于明桿良工閥門(mén)閥門(mén)的閥桿外徑。良工閥門(mén)閥門(mén)的啟閉速度快，容易產(chǎn)生水擊現(xiàn)象。所以，應(yīng)根據(jù)使用條件的不同，選擇合適的啟閉速度。安裝、連接方式：良工閥門(mén)閥門(mén)的安裝方式包括垂直安裝、水平安裝、落地安裝。
Thread pitch of the pattern, mm; Z is the number of valve stem threads For multi rotating rising stem valves, if the large stem diameter allowed by the actuator cannot pass through the valve stem of the equipped valve, it cannot be assembled into an electric valve. Therefore, the inner diameter of the hollow output shaft of electrical equipment must be greater than the outer diameter of the stem of the rising stem valve. The opening and closing speed of Lianggong valve is fast, which is prone to water hammer phenomenon. Therefore, the appropriate opening and closing speed should be selected based on different usage conditions. Installation and connection methods: The installation methods of Lianggong valve include vertical installation, horizontal installation, and floor installation.
