Explain the detailed method of correctly operating the valve

Before operating the valve, read the operating instructions carefully. Be sure to know the flow direction of the gas before operation, and pay attention to check the valve opening and closing signs. Check the appearance of the valve to see if the valve is damp. If it is damp, it should be dried. If any other problems are found, they should be dealt with in time, and no faulty operation is allowed. If it is an electric valve that has been out of use for more than 3 months, check the clutch before starting, confirm that the handle is in the manual position, and then check the insulation, steering and electrical wiring of the motor.

Correct operation method of manual valve

Manual valve is the most widely used valve. Its handwheel or handle is designed according to ordinary manpower, considering the strength of the sealing surface and the necessary closing force. Therefore, it is not possible to use a long lever or a long wrench to move the board. Some people are accustomed to using a wrench, and they should pay strict attention to it. When opening the valve, the force should be stable and avoid excessive force, which will cause the valve to be opened and closed. The force should be stable and not impacted. Some components of high-pressure valves that are opened and closed by impact have already considered this impact force and cannot be equal to ordinary valves.
