Description

Technical Field

[0001] The utility model relates to the technical field of valve switches, in particular to a combined valve opening and closing device. Background Art

[0002] The valve, a seemingly simple device, is actually the core part of fluid control. It is a device that can control the flow of fluid and is widely used in various industrial fields, such as chemical, petroleum, and electricity. The main function of the valve is to regulate the flow, pressure, and direction of the fluid to ensure the safe and stable operation of the system. Valves play a vital role in industrial production. From the inlet and outlet control of chemical reactors, to the oil product diversion of oil pipelines, to the steam regulation of power systems, the precise control of valves is the key. While achieving these functions, valves also need to withstand a variety of harsh working conditions such as high temperature, high pressure, and corrosion, so their quality and performance are crucial. There are many types of valves, which can be divided into stop valves, gate valves, ball valves, butterfly valves, etc. according to different working principles and application requirements. They are used in corresponding occasions according to their functions and structural characteristics.

[0003] Valves play a huge role in modern industry, which is mainly reflected by the opening and closing of valves, so opening and closing valves has become a common operation. Due to the complexity of the production site, valves are located in various positions, some valves are buried deep underground, and some valves are suspended in the air. These valve operations often require entering the valve pool or climbing onto the platform to operate the valve to complete the connection and cutoff of the medium.

[0004] In the prior art, when opening and closing valves in a valve pool or on a platform, it is necessary to use a pipe clamp F-type wrench or a T-type wrench. When opening and closing valves, operators often need to open and close several valves of various positions and sizes, so they need to carry several types of wrenches, which is troublesome and laborious to carry tools. Sometimes, if the tools they carry are not suitable, they need to go back and get the right tools, resulting in lower work efficiency. Therefore, it is urgent to study how to complete the opening and closing of valves of different models and positions more quickly and efficiently. Utility Model Content
