Valve body with internal adjustable lifting sealing mechanism

Abstract

The invention relates to the technical field of valve assembly parts, in particular to a valve body with an internal adjustable lifting sealing mechanism. The valve body comprises an upper valve shell, a lower valve shell, a top control rod and a lateral conveying pipe. According to the valve body with the internal adjustable lifting sealing mechanism, the upper valve shell, the lower valve shell, the top control rod and the lateral conveying pipe are arranged in a split type structure, and are fixed in a threaded assembly mode, so that the valve body is convenient to disassemble and fix, and the later maintenance and replacement cost is lower; an elastic lifting locking mechanism is arranged on an upper internal thread assembling groove, a lateral adjustable connecting support used for connecting the elastic lifting locking mechanism and the top control rod is installed in the upper valve shell, the connecting end of the lateral conveying pipe can be limited and closed according to the elastic lifting locking mechanism, the sealing performance of the assembling end is improved, and meanwhile, the lateral conveying pipe at the required position can be independently subjected to flow regulation and flow interception according to needs, so that the functionality and the application range are greatly improved.

Description

technical field [0001] The invention relates to the technical field of valve assemblies, in particular to a valve body with an internal adjustable lifting and closing mechanism. Background technique [0002] The gate valve is a gate of the opening and closing part. The direction of movement of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate valve is sealed by the contact between the valve seat and the gate, and usually the sealing surface will be surfacing with metal materials to increase wear resistance. According to the different gate valves, gate valves are divided into rigid gate valves and elastic gate valves. [0003] The opening and closing part of the gate valve is the gate, and the movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. ...

AI Technical Summary

Problems solved by technology

[0006] The technical problem to be solved by the present invention is: in order to solve the problems existing in the above-mentioned background technology, an improved valve body with an internal adjustable lifting and closing mechanism is provided to solve the problem that the traditional gate valve has a simple structure, and most of them are fixed in one body. It needs to be quickly disassembled. Once it is partially damaged, it can only be discarded and replaced as a whole. The cost of later maintenance and use is very high. At the same time, the flow rate and closure sequence of different delivery pipes cannot be freely adjusted according to needs, resulting in a problem of single and limited functionality and applicability.
