AI Technical Summary
Technical Problem
In existing pressure reducing valves, gaps are easily generated between the sealing cylinder and the core block, leading to fluid leakage and poor sealing performance.
Method used
The valve core sealing structure adopts an integral vulcanization type, including a vulcanization block and a vulcanization pad. The vulcanization pad is made of a relatively hard vulcanized rubber material, and the connection stability between the vulcanization block and the vulcanization pad is enhanced by structures such as locking nuts and center bolts, thereby reducing gaps.
Benefits of technology
It improves the sealing performance between the valve core and the sealing screw, reduces fluid leakage, and enhances the overall sealing performance of the valve body.

Abstract
This application relates to an integrally vulcanized valve core sealing structure, belonging to the field of valve sealing structures. It includes a valve body and a valve core, with the valve core slidably connected within the valve body. The valve core includes a core block, a spring, and a sealing screw. The sealing screw is installed inside the valve body, and the core block is slidably connected within the valve body. One end of the spring abuts against the valve body, and the other end abuts against the core block. The core block includes a vulcanized block and a vulcanized pad, which are connected. The vulcanized block is slidably connected within the valve body, and the vulcanized pad abuts against the sealing screw. This application improves the sealing performance of the valve body.
