Problems solved by technology

[0002] The use of manual shut-off valves is quite common, but the current manual shut-off valves are all single-piece. Due to the large area of ​​the valve, there is a large back pressure under the action of compressed air. It takes a lot of arm strength to open the valve. The force is large, often improper force, causing the pressure rod support ear seat to break

Abstract

The invention discloses a manual stop valve, which comprises a valve body, wherein a valve cover is arranged on the valve body, a large valve core is arranged in the valve body, a small valve core is embedded in the large valve core, six to ten slotted grooves are formed on the large valve core, the manual stop valve also comprises a compression bar connected to the valve body through an axle pin, the small valve core and the valve cover are connected through a spring, a mechanism formed by the large valve core and the small valve core is connected with the compression bar through a support rod, the support rod is fixedly connected to the bottom of the small valve core, a nut and a gasket are arranged at the fixed connection position, and the nut and the gasket make the small valve core in a center hole of the large valve core. The stop valve has the advantages of simple structure, long service life, easy operation and labor saving.

Description

technical field [0001] The invention relates to a shut-off valve, in particular to a manual shut-off valve. Background technique [0002] The use of manual shut-off valves is quite common, but the current manual shut-off valves are all single-piece. Due to the large area of ​​the valve, there is a large back pressure under the action of compressed air. It takes a lot of arm strength to open the valve. The force is large, and often the force is improper, causing the pressure bar to support the ear seat to break. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the present invention provides a manual shut-off valve, which can be opened only with relatively small force. [0004] In order to solve the above technical problems, the manual shut-off valve of the present invention mainly includes a valve body, the valve body is provided with a valve cover, and a large valve core is arranged in the valve body, and a small valve core is emb...
