Problems solved by technology

[0005] The present invention can solve the following problems that the existing cut-off valve may encounter during use: a. The installation and disassembly process is relatively cumbersome, and the operation is professional and time-consuming, resulting in poor practicability; b. The existing cut-off valve The valve often needs to apply a large force to control the opening and closing of the valve, which is easy to increase the resistance of the user, which makes the globe valve very inconvenient to use, thus reducing its use effect

Abstract

The invention relates to a quick insertion type stop valve. The valve comprises a valve body, a clamping device, a sealing device and a cut-off device, the clamping device is arranged at the left end of the interior of the valve body, the sealing device is arranged on the right side of the clamping device, the cut-off device is installed on the right side of the sealing device, and the cut-off device is arranged in the middle of the valve body. The valve can solve the following problems that may be met in the using process of an existing stop valve, a, the mounting and dismounting processes are tedious, the operation speciality is high, time and labor are consumed, and thus the practicability of the existing stop valve is poor; and b, it is often required to apply a large force to control the opening and closing of the existing stop valve, the use resistance to a user is prone to be increased, the stop valve is very inconvenient to use, and the use effect of the stop valve is reduced.

Description

technical field [0001] The invention relates to the field of stop valves, in particular to a quick-insert stop valve. Background technique [0002] The globe valve, also known as the gate valve, can be used to cut off and regulate the flow of fluid. Due to the small friction between the sealing surfaces during the opening and closing process, it is relatively durable, the opening height is not large, it is easy to manufacture, and it is convenient to maintain. It is not only suitable for medium and low pressure, but also suitable for high pressure, so the globe valve is very popular. The shut-off principle of the globe valve is to make the sealing surface of the valve disc and the sealing surface of the valve seat fit closely through the valve pressure, thereby preventing the flow of the medium and achieving the purpose of shutting off. [0003] At present, the existing globe valves may encounter the following problems during use: a. The installation and disassembly process...
