Abstract

A full-closed bidirectionally sealed plug-in plate valve is composed of a valve body with pressure meter and N2 inlet, oblique or parallel front and back valve plates, an end cover of valve body, a cylinder unit between said valve plates and with push rod linked to said front and back valve plates, two pneumatic sealing rings for said valve plates, and a reverse valve in the internal hole of said push rod and connected to an external control cylinder.

Description

technical field [0001] The invention relates to the technical field of gate valves, in particular to a fully enclosed two-way sealing gate valve. Background technique [0002] The gate valve is a valve with a wide range of uses. There are more or less problems in the various plug-in valves currently used. The main reason is that the sealing effect is not ideal; There is no visual observation and understanding of the working status of the valve body; the inside of the valve body cannot be cleaned in time. The reason is that the structure of the valve is not reasonable enough, the sealing measures are not comprehensive enough, and the control means are not perfect enough. Utility model patent 02218950.5 high-performance flapper valve, its valve body assembly is composed of front valve body, rear valve body and middle valve body, corrugated expander is arranged on the corresponding surface of middle valve body and front valve body, valve plate assembly and valve body The sea...
