A valve that can adjust the length of the handle according to the space

Abstract

The invention discloses a valve whose handle length can be adjusted according to space, comprising a valve body, a mounting plate is arranged on the top of the valve body, and a valve rod is arranged inside the valve body. In the present invention, a limit rod, a limit hole, a limit groove, a first slide block, a first chute, a bearing, a rotating mechanism and a limit mechanism are used together, and the limit rod passes through the limit hole and is inserted into the limit The position slot can fix the position of the moving block, so as to achieve the purpose of adjusting the height of the handle position. Through the use of the first slider and the first chute, the jamming phenomenon of the movable rod is avoided. Through the use of bearings , which improves the speed and smoothness of the movable rod rotation. Through the use of the rotating mechanism, the valve stem can be rotated on the basis of adjusting the height of the handle. Through the use of the limit mechanism, it is convenient to adjust and fix the length of the handle. .

Description

technical field [0001] The invention belongs to the technical field of valves, in particular to a valve whose handle length can be adjusted according to space. 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. [0003] The valve is widely used in many fields due to its strong control of the fluid del...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the problems existing in the prior art, the present invention provides a valve that can adjust the length of the handle according to the space, which has the advantage of multi-position adjustment of the valve handle, and solves the problem of uncertain installation space of the existing valve during installation. As a result, during the installation process of the valve, the handle of the valve takes up a lot of space, which increases the difficulty of installing the valve. At the same time, because of the fixed shape of the valve handle, it is easy to cause the problem that it is not convenient to rotate the valve stem in a narrow space.
