An explosion-proof valve

By setting a baffle, connecting rod, and sealing plug structure at the explosion-proof valve interface, and utilizing the deformation of the rubber sleeve and the pushing of the tail rod, the sealing plug is automatically closed, solving the problem of foreign objects entering during installation, ensuring the valve's sealing performance and normal mechanism response, and improving the safety and reliability of the explosion-proof valve.

AI Technical Summary

Technical Problem

During the installation of existing explosion-proof valves, foreign objects such as metal shavings, dust, and sealant residue can easily fall into the open interface, causing wear on the valve sealing surface, jamming of moving parts, or delayed response of the triggering mechanism, affecting the explosion-proof effect and creating safety hazards.

Method used

Design an explosion-proof valve that uses a baffle, connecting rod, and sealing plug structure at the interface to automatically close the sealing plug by the deformation of the rubber sleeve and the push of the tail rod, thus preventing foreign objects from entering the interface.

Benefits of technology

It effectively prevents foreign objects from entering the valve body during installation, ensuring the valve's sealing and normal mechanical response, and improving the safety and reliability of the explosion-proof valve.

Abstract

This utility model discloses an explosion-proof valve, including a valve body with two ports on one side. A junction box is installed at one end of the valve body. A mounting seat is installed on the outer wall of the valve body on one side of each port via a rotating shaft. A connecting rod is fixedly installed on the outer wall of one end of the mounting seat, and the other end of the connecting rod connects to one end of a baffle. In this utility model, when connecting the port to the outer wall pipe, the two baffles can be flipped downwards from one side of the mounting seat via the connecting rod and a movable ball. This causes the baffles to move the sealing plug closer to the opening end of the port. After the sealing plug connects to the port, one end of the rubber sleeve is compressed and deformed. The compression force applied when the rubber sleeve deforms to one end is applied to the tail rod, which further pushes the sealing plug into the port. Finally, the sealing plug seals the port, thus preventing small foreign objects from falling into the port during valve body installation and affecting the normal operation of the valve body.
