Product characteristics and maintenance of instrument needle valve
Instrumentation needle valve features generally have two kinds, the use of features and structural features. It determines the main use of the valve performance and scope of use, belonging to the use of the valve characteristics are: the category of the valve, product type, valve main parts, valve transmission mode. It determines the pneumatic ball valve valve installation, repair, maintenance and other methods of some structural characteristics.
Belong to the structural characteristics of: the structural length of the valve and the overall height, the form of connection with the pipeline, the form of the sealing surface, the form of valve stem structure.
1. Regularly check the height of the oil level in the oil level gauge, refuel the oil mist as appropriate, and regularly remove the condensate and impurities that accumulate dust at the bottom of the cup of the moisture overconsiderer.
2. Check the pressure of the gas source and adjust the flow rate of the one-way throttle valve so that the valve has enough opening and closing force and flexible action.
3. Check whether the detection hole leakage or water leakage, water leakage leakage is required to replace the seals in a timely manner.
4. Conclusion high-pressure water descaling injection valve should not only be stable and controllable operation, but also pay attention to the safe operation.
