Quick-release type safety control mechanism for valve body

Abstract

The invention relates to the technical field of valve sealing forgings, in particular to a quick-release type safety control mechanism for a valve body. The quick-release type safety control mechanism comprises a main shell and lateral conveying pipes. The quick-release type safety control mechanism for the valve body is formed by fixing split type shells through bolts, internal guide frames and arc-shaped guide plates on the inner side face of a left shell and the inner side face of a right shell are matched with internal closing devices for assembly, and opening and closing of arc-shaped conveying openings are controlled through lifting of the internal closing devices, so that the structural requirement of the valve body sealing structure on the inner wall is reduced; and meanwhile, the quick-release type safety control mechanism is convenient to assemble and disassemble, the later use cost is reduced, and the application range is very wide; installation is convenient, local replacement can be achieved once damage occurs, and the maintenance difficulty is greatly reduced; through the built-in design, the integration degree is improved, functionality and safety are greatly enhanced, and meanwhile the structure is more compact; and a thread adjusting and guiding mechanism can be formed in the main shell and can be directly matched with an existing control rod, so that disassembly and assembly are convenient.

Description

technical field [0001] The invention relates to the technical field of valve sealing forgings, in particular to a quick-release safety control mechanism for a valve body. Background technique [0002] Valves are pipeline accessories used to open and close pipelines, control the flow direction, and adjust and control the parameters (temperature, pressure and flow) of the conveying medium. In the fluid piping system, the valve is the control element whose main function is to isolate the equipment and the piping system, regulate the flow, place the return flow, regulate and discharge the pressure. It can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. [0003] There are complete types of valves, mainly divided into 12 categories such as gate valve, globe valve, throttle valve, plug valve, ball valve, electric valve, diaphragm valve, check valve, safety valve, pressure reduc...

AI Technical Summary

Problems solved by technology

[0005] 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 quick-release safety control mechanism for the valve body is provided, which solves the problem that the traditional valve body is integrally fixed and cannot be quickly adjusted to the valve as required. As a result, once a problem occurs, it can only be replaced as a whole. The cost of maintenance and replacement is high, and the scope of application is limited. At the same time, during the opening and closing process of the valve body, a water hammer effect will occur, which seriously affects the safety of the entire pipeline. and service life issues
