Waterproof valve protection device good in heat preservation effect

Abstract

The invention discloses a waterproof valve protection device good in heat preservation effect. The waterproof valve protection device comprises a first shell. The first shell comprises a first valve body protection shell and a first valve rod protection shell. The middle of the upper end of the first valve body protection shell is fixedly connected with the first valve rod protection shell. One side of the first shell is fixedly connected with a second shell. The second shell comprises a second valve body protection shell and a second valve rod protection shell. The middle of the upper end of the second valve body protection shell is fixedly connected with the second valve rod protection shell. The two ends of the upper surface of the first valve body protection shell and the two ends of the upper surface of the second valve body protection shell are fixedly connected with first connecting parts. The waterproof valve protection device good in heat preservation effect has the beneficial effects of being simple in structure, convenient to use, good in heat preservation effect and waterproof effect and the like; and the problems that in a valve in the humid environment, water is prone to entering a clearance between a covering layer and the valve, and a heat preservation layer in the valve loses the heat preservation function are solved.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a waterproof valve protection device with good thermal insulation effect. Background technique [0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to its function, it can be divided into shut-off valve, check valve and regulating valve. The valve is a control component in the fluid delivery system, which has functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems range from the simplest cut-off valves to various valves used in extremely complex automatic control systems, with a wide variety of varieties and specifications. Valves can be used to control the flow of various types of fluids such as air, water...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a waterproof valve protection device with good thermal insulation effect, which has the advantages of simple structure, convenient use, good thermal insulation and waterproof effect, etc., and solves the problem that water is easy to enter the coating in a humid environment. The gap between the layer and the valve makes the insulation layer in the valve lose its insulation effect
