进口水封闸阀Principle:

By operating the valve rod, the movement of the valve plate can be controlled, so as to realize the opening and closing of the water seal gate valve. The annular stop can limit the upward position of the valve plate and prevent the valve plate from flying out of the upper valve seat when subjected to excessive pressure. The annular seal plate is pressed on the annular stop through the circlip and pressing plate, and the annular seal plate separates the cavity formed by the combination of the lower through hole and the upper through hole from the packing cavity, so as to realize the sealing at the connection between the valve rod and the annular stop, Prevent the packing from flowing into the flow pipeline of the lower valve seat. During use, the liquid level gauge can measure the volume of the packing in the packing cavity, and the pressure gauge can measure the pressure of the medium in the flow pipeline, so as to know whether the packing is sufficient and whether it is necessary to add packing
