Description

Technical Field

[0001] The utility model relates to the technical field of pipeline gate valves, in particular to a pipeline gate valve which is easy to disassemble and assemble. Background Art

[0002] The opening and closing part of the gate valve is the gate. The movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate has two sealing surfaces. The gate valve is sealed through the contact between the valve seat and the gate. Usually the sealing surface will be welded with metal materials to increase wear resistance. When the gate valve is in use, it needs to be installed on the surface of the pipe first.

[0003] A Chinese utility model patent with application number 202320954330.9 proposes a pipeline gate valve that is easy to disassemble and assemble, including a valve body and an end plate, the end plate is installed at both ends of the valve body, a valve plate is installed in the valve body, the valve plate is connected to the adjustment component, and also includes a mounting plate. The utility model provides a pipeline gate valve that is easy to disassemble and assemble, the valve body, the end plate and the mounting plate can be connected to the pipeline through bolts and nuts, and the corresponding nuts and bolts can be removed during disassembly, and the loading and unloading are relatively convenient. At the same time, the disassembled mounting plate can be used to clean the inner wall of the filter component by rotating the cleaning component, and the impurities adhering to the inner wall of the filter component will be swept off. The impurities on the inner wall of the filter component can be cleaned by shaking the mounting plate or flushing with water. The filter component includes a spherical cavity and a conical cavity. After the liquid enters, its internal space changes from narrow to wide, so that impurities are not easy to flow back, and the pipeline is prevented from being blocked by the backflow of impurities filtered by the valve body.

[0004] After being improved, the above-mentioned device can avoid the situation where the pipeline is blocked due to the backflow of impurities filtered by the valve body by setting up a cleaning component and a filtering component. However, during use, the connection between the valve body and the pipeline is connected with bolts and nuts. During installation and disassembly, the bolts and nuts need to be installed and disassembled one by one, which is time-consuming and labor-intensive. For this reason, we propose a pipeline gate valve that is easy to disassemble and assemble. Utility Model Content
