氣動球閥在操作中應該留意什么：
What should be paid attention to in the operation of pneumatic ball valve:
1.氣動球閥在運轉(zhuǎn)過程中應順時針關(guān)閉啟閉方向。
1. The pneumatic ball valve should close the opening and closing direction clockwise during operation.
2.由于管網(wǎng)中的氣動閥通常是手動啟閉的，所以不應該有太多的啟閉轉(zhuǎn)數(shù)，即大口徑閥門也應該在200-600轉(zhuǎn)。
2. Since the pneumatic valve in the pipe network is usually opened and closed manually, there should not be too many opening and closing revolutions, that is, the large-diameter valve should also be 200-600 revolutions.
3.在管道工壓條件下，更大的啟閉力矩應為240n-m，以便當一個人的啟閉操作。
3. Under the pressure of the plumber, the larger opening and closing torque should be 240n-m, so that when one person opens and closes.
4.氣動球閥的啟閉操作端應為方榫，尺寸應規(guī)范化，面向空中，以便人們能夠直接從空中操作。帶輪盤的閥門不合適公開管網(wǎng)。球閥廠家。
4. The opening and closing operating end of the pneumatic ball valve should be a square tenon, and the size should be standardized, facing the air, so that people can operate directly from the air. The valve with wheel disc is not suitable to open the pipe network. Ball valve manufacturer.
5.氣動球閥的顯現(xiàn)盤。
5. Display disc of pneumatic ball valve.
(1)氣動球閥的啟閉度刻度線應在變速箱蓋或轉(zhuǎn)換方向后的顯現(xiàn)盤的外殼上鑄造，均面向空中，刻度線涂上熒光粉；
(1) The opening and closing scale of the pneumatic ball valve shall be cast on the gearbox cover or the shell of the display disk after changing direction, both of which face the air, and the scale shall be coated with fluorescent powder;
②不銹鋼板可用于指示盤針好的狀況下能夠運用不銹鋼板，否則不應運用鋁板作為刷漆的鋼板；
② Stainless steel plate can be used to indicate that stainless steel plate can be used when the dial needle is good, otherwise aluminum plate should not be used as the steel plate for painting;
③指示盤針頭醒目，固定結(jié)實，一旦啟閉調(diào)整精確，應用鉚釘鎖住。
③ The needle of the indicator plate is eye-catching and firmly fixed. Once the opening and closing adjustment is accurate, it should be locked with rivets.
