Description

Governing valve assembly and disassembly tools

Technical Field

The utility model belongs to the field of mounting and dismounting of regulating valves, and particularly relates to a regulating valve dismounting tool.

Background

The regulating valve is a valve suitable for media such as air, water, steam and the like, can regulate the flow of the media according to requirements, and is widely applied to fluid medium pipeline transmission equipment. The adjusting valve is widely applied to industry and life, in the life of residents, the adjusting valve is mainly used for adjusting the flow of water for the residents, and various structures are made according to different required positions, for example, a civil angle valve is one of the civil adjusting valves, and the structure and the characteristics of the civil angle valve are modified by a spherical adjusting valve. The difference from a ball-type regulator valve is that the outlet of the angle valve is at a 90 degree right angle to the inlet. The angle valve is also called triangle valve, angle valve, and angle water valve. This is because the pipe has a 90-degree corner shape at the angle valve, and is called an angle valve, or a dog-leg water valve. The basic structure of the angle valve is that a water outlet pipe is vertically processed on the side wall of a main pipe of the angle valve, the lower end of the main pipe of the angle valve is a water inlet and is provided with external threads, and a water outlet of the water outlet pipe is provided with the external threads. The angle valve is widely applied to the production and living fields of people. For example, the angle valve for civil use is widely applied to the wall of a civil building, the shell of the angle valve for civil use is formed by die sinking and pouring, and the pipe wall is relatively thin in order to save cost, so that the main pipe of most angle valves for civil use is cylindrical in shape. If the hexagonal edge is processed on the outer wall of the main pipe, the die sinking cost and the manufacturing cost are greatly increased.

When installing this type of angle valve usually adopt bare-handed mounting means, twine the unsintered tape on the water inlet external screw thread that the angle valve is responsible for promptly, then aim at the internal thread mouth of pipe of wall and rotate bare-handed until screwing up the angle valve. However, the hand strength of people varies from person to person, and some people have small hand strength, cannot screw the angle valve in place, and easily make the hand slippery, and the orientation of the outlet nozzle of the angle valve is not aligned with the orientation of the pipeline to be connected, for example, the originally planned outlet nozzle of the valve body is upward, but only can be screwed to the outlet nozzle obliquely downward. The angle valve can be continuously rotated to enable the water outlet pipe mouth to be in place only by applying enough external force under the condition that the number of winding turns of the raw material belt discharged from the water inlet pipe mouth is large. However, the problem that people with small hand strength have difficulty, due to the fact that the pipe wall is round, a monkey wrench cannot be used, no corresponding proper tool exists in the market, and the problem that the civil angle valve is time-consuming and labor-consuming to disassemble and assemble is caused.
