Abstract

The multifunctional pneumatic control check stop valve comprises an air cylinder, a heat insulation support and a valve body, the valve body is provided with an inlet end and an outlet end, the air cylinder is connected with the valve body through the heat insulation support, and an end cover is installed at the position, located on the valve body, of a piston rod of the air cylinder. A valve element assembly is installed at the position, located at the inlet end of the valve body, of a piston rod of the air cylinder, a one-way valve assembly is installed at the outlet end of the valve body and comprises a one-way valve element, a spring and a spring gasket, the one-way valve element and the spring gasket are located at the two ends of the spring respectively, and the spring gasket comprises a gasket protrusion. A bolt penetrating notch is formed in the gasket bulge; a gasket mounting groove used for mounting a spring gasket is formed in the outlet end of the valve body, and a gasket limiting protrusion corresponding to the gasket protrusion is arranged at the position, located at the gasket mounting groove, of the valve body. The valve element is driven by compressed air power, the valve element is normally opened when no air pressure is input, and a loop is kept in one-way cut-off.

Description

technical field [0001] The invention relates to the technical field of cut-off valves, in particular to a multifunctional air-controlled non-return stop valve. Background technique [0002] Globe valves are widely used due to their small sealing surface friction and short opening and closing strokes during the opening and closing process. The traditional globe valve includes a valve body, a valve disc, a valve stem and a hand wheel. The valve stem is raised and lowered by the rotation of the hand wheel. The valve body is provided with a seal that cooperates with the valve disc. When the seal is squeezed with the valve body, the flow path is closed, and when the valve body is separated from the seal, the flow path is opened. [0003] Our company has applied for a multi-functional pneumatic control check valve for multi-media; but it is not convenient to disassemble and assemble the one-way valve assembly. Contents of the invention [0004] The purpose of the present inven...
