Description

Technical Field

[0001] The utility model relates to the field of valves, in particular to a valve installation structure. Background Art

[0002] A valve is a device used to control the flow of fluids (liquids, gases, steam, etc.). It can control the flow, pressure, direction, speed and other parameters of the fluid by opening or closing or adjusting the valve. The valve is usually composed of a valve body, a valve cover, a valve core, a valve seat and other components. According to the different control methods of the valve, it can be divided into manual valves and automatic valves. Common valve types include ball valves, gate valves, butterfly valves, stop valves, regulating valves, etc. Valves are widely used in industry, construction, agriculture, fire protection, energy and other fields. The existing valve installation structure is a valve structure that is easy to install, such as the publication number CN220749181U, including a valve body, the left end of the valve body is connected to the first valve pipe, the left end of the first valve pipe is provided with a locking ring, the left end of the sealing rubber ring is provided with a sealing disc, the right end of the valve body is connected to the second valve pipe, the second valve pipe is provided with an expansion pipe, the right end of the second valve pipe is provided with a locking ring, and a fastening card is provided above the locking ring. The fastening card is C-shaped, and a quick ball head is provided above the fastening card.

[0003] When the above structure is in use, the pipeline is passed through the locking ring, the valve bolt and the expansion tube into the valve body, and the valve bolt is driven to rotate by rotating the locking ring. The valve bolt is locked through the threaded connection of the threaded groove and the expansion tube is squeezed at the same time, thereby locking the pipeline; when the valve is damaged and needs to be disassembled and sent to the factory for repair, since the pipeline passes through the locking ring, the valve bolt and the expansion tube into the valve body, it is necessary to drag the pipeline outward during disassembly, and the existing pipelines are made of metal, are long, and have a certain weight, so it is more laborious to drag the pipeline, and even some pipelines are fixedly installed on walls or other objects and cannot be dragged. For this reason, we propose a valve installation structure. Utility Model Content
