How to maintain and keep the valve in good condition？
Long-term storage of valves should be checked regularly. The exposed surface must be kept clean and free of dirt. The ball valve should be blocked at both ends and open when stored. Gate valves, globe valves, check valves, both ends of the passage should be blocked and closed, neatly stored in a ventilated and dry place indoors, and prohibited to be stacked or stored in the open air.
Before installation, the pressure of the valve mark must be carefully checked, whether the diameter meets the requirements for use, the defects caused by the transportation process are eliminated, and the dirt of the valve member is eliminated.
When installing, the valve can be directly connected to the pipeline by connection. Under normal circumstances, it can be installed at any position of the pipeline, but it is easy to operate. Note that the flow direction of the shut-off valve should be upward from the longitudinal valve flap. The lift check valve can only be installed horizontally.
When ball valve, globe valve and gate valve are used, they are only fully open or fully closed. It is not allowed to adjust the flow to avoid erosion of the sealing surface and accelerate wear. The gate valve and the upper thread stop valve have a reverse sealing device, and the hand wheel is screwed to the uppermost position to prevent the medium from leaking from the packing.
The ball valve, globe valve, and gate valve should be applied with the handwheel when opening or closing. Do not use levers or other tools to avoid damage to the valve. The handwheel rotates clockwise to close, and vice versa.
The bolts of the packing gland should be evenly tightened and should not be pressed into a squat state to prevent the bump from moving or causing leakage.
During the use of the valve, it should be kept clean at all times. The transmission thread must be lubricated regularly. When the fault is found, stop using it immediately and find out the cause to solve the problem.
