Description

Technical Field

[0001] The utility model relates to the field of valve boxes, in particular to a hydraulic end valve box with an interface anti-detachment structure. Background Art

[0002] A valve box is a device used to control the flow of liquid or gas in a pipeline. It is usually installed on the pipeline. The main function of the valve box is to adjust and control the flow and pressure of the fluid by opening, closing or adjusting the valve. The valve box can contain one or more valves, such as stop valves, regulating valves, check valves or safety valves. These valves can be used alone or combined into a combination, namely the valve box. The design of the valve box can be single-row or double-row, and can be made into a duplex or multi-connection type according to needs. The valve box can be cast as a whole from materials such as cast iron, or connected through a "combination valve";

[0003] Most of the valve boxes in the prior art have a simple structure, and the valve box interface is screwed and fixed to the external pipe through a threaded structure. However, the interface thread is prone to loosening and slipping after long-term use, which can easily cause the external pipe and the valve box interface to loosen and fall off, affecting the safe use of the valve box. At the same time, most of the external pipe parts of the existing valve box are directly connected to the outside of the valve box and do not have the ability to clamp and fix it. When the pipe body is subjected to external force, the interface is prone to being pulled. Therefore, we need to upgrade and transform the existing technology to overcome its problems and shortcomings. Utility Model Content
