Why does the maintenance plan of electric eccentric butterfly valve burn simulation module? 1、 Floating pneumatic ball valve The ball of the pneumatic ball valve floats. Under the pressure of the medium, the ball can move to a certain extent and press against the sealing surface at the outlet end to ensure the outlet end is sealed. The floating pneumatic ball valve has a simple structure and good sealing performance, but the load of the working medium borne by the ball is all transferred to the outlet seal ring, so it is necessary to consider whether the seal ring data can fully withstand the working load of the ball medium. This structure is widely used for medium and low pressure ball valves.
、 Second, as the leakage stoppers of pneumatic switch ball valves, they should have a certain sense of responsibility, because they can skillfully operate the device with rich experience, so the leakage stoppers should not be too many, and 1-2 people should be skilled.
