Protection device for valve

Abstract

The invention discloses a protection device for a valve. The protection device comprises a valve body, a protection shell, clapboards, a shell body, a seal ring, a vertical shaft, clamping grooves, aseal plug, a first spring, a valve clack, a second spring, a rotating rod, a sleeve pipe, a fixed shaft, a sleeve shaft, a rotary knob, a fixed plate, a clamping rod, position-limiting plates and a bearing. The protection device for the valve is simple in structure and convenient to use, by means of protection of the protection shell, the situation that the valve is exposed to air all the time isavoided, long-time use of the valve is facilitated, shortening of the service life caused by valve corrosion is avoided, and by means of seal of the sleeve pipe on the side end of the protection shell, the fact that the valve inside the protection shell is not corroded by the air is facilitated; and according to the protection device for the valve, opening and closing of the valve are facilitatedby rotating the rotating rod, and moving of the clamping rod is driven by rotating the rotary knob, fixing of the vertical shaft is facilitated, valve misoperation caused by unguarded collision is avoided, causing of loss is effectively avoided, and the safety performance of the valve is improved.

Description

technical field [0001] The invention relates to a protection device, in particular to a protection device for valves, and belongs to the technical field of valve applications. Background technique [0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, adjust and control the parameters of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are important components in the fluid conveying system. Control components, with the functions of cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief, etc., are used in the valves of fluid control systems, from the simplest cut-off valve to the various valves used in extremely complex automatic control systems. There are many types and specifications of valves. Valves can be used to control the flow of various types of fluids such as ai...

AI Technical Summary

Problems solved by technology

[0003] Valves currently on the market are devices used to control the direction, pressure, and flow of fluids in fluid systems. They are devices that make or stop the flow of media in piping and equipment and can control their flow. Usually, there are rotary and wrench However, for wrench-type valves, when not in use, misoperation may be caused by careless knocking, resulting in abnormal opening and closing of the valve, resulting in unnecessary losses; and the long-term use of the valve may cause Corrosion of the valve, resulting in a reduction in the service life of the valve
