Problems solved by technology

[0006] 1. The valve protective cover is troublesome to install, and it is inconvenient to disassemble after covering it, and the replacement cost is high. If it is not replaced in time, the valve still cannot be protected;
[0007] 2. During the use of the valve, the insulation shell is usually required to have a thermal insulation effect on the valve. The thermal insulation effect of this equipment is not obvious. When the valve is in a low temperature working environment, the valve protective cover cannot play a good role in the valve. Protective effect, the valve is easily damaged by freezing

Embodiment 1

[0035] Example 1 see Figure 1-7 , the present invention provides the following technical solutions: a valve shield that is easy to disassemble, including: the valve body 2, the shell 1 and the clamping mechanism 9 are composed of three parts.

[0036] Wherein the valve body 2 is a metal casting;

[0037] The shell 1 is assembled from detachable parts, including a front cover 11 and a rear cover 12, the front cover 11 is formed on the left side of the valve body 2, the rear cover 12 is formed on the right side of the valve body 2, the front cover The bottom of shell 11 and rear cover 12 is provided with hinge 3, and hinge 3 is respectively fixedly connected between front cover 11 and rear cover 12 by bolt, and the bottom of front cover 11 and rear cover 12 is connected by hinge 3 rotation The front cover 11 and the rear cover 12 are symmetrical stainless steel covers, and the front cover 11 and the rear cover 12 can cover the valve body 2 for protecting the valve body 2 .

...

Embodiment 2

[0041] Embodiment 2 is on the basis of embodiment 1 such as figure 2 As mentioned above, the joint portion of the front cover 11 and the rear cover 12 encloses a horizontal through hole 13 extending in the horizontal direction and a vertical through hole 14 vertically communicating with the horizontal through hole 13 .

[0042] In this embodiment: in order to fit the valve body 2, the horizontal perforation 13 is used to accommodate the valve body, and the vertical perforation 14 is used for the valve stem to pass upwards.

Embodiment 3

[0043] Embodiment 3 is such as on the basis of embodiment 1 figure 2 As mentioned above, the inner wall of the horizontal perforation 13 along the two ends along the length direction and the inner wall of the vertical perforation 14 are provided with rubber rings 7 .

[0044]In this embodiment: in order to ensure the tightness between the valve body 2 and the casing 1, rubber rings 7 are arranged on the inner walls of the openings of the horizontal perforation 13 and the vertical perforation 14, and the rubber rings 7 are provided to seal the valve body 2. The gap between the valve body and the shell 1 prevents the corrosion of the internal valve body 2 due to excessive gap.

Description

technical field [0001] The technical field of the valve protection cover of the present invention, in particular relates to a valve protection cover which is easy to disassemble. Background technique [0002] The valve is a control component in the fluid delivery system. It has the functions of cut-off, reverse flow, reverse flow prevention, pressure stabilization, diversion or overflow pressure relief, etc. It is used for the valve of the fluid control system. From the simplest cut-off valve to various valves used in extremely complex automatic control systems, there are quite a variety of varieties and specifications. Valves 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] The invention with the existing application number CN201711256975.0 discloses a valve protective cover, which includes an outer cover and a cover plate. Side plates are connected to the l...
