[0002] Water supply and drainage generally refers to the urban water supply system and drainage system, referred to as water supply and drainage. The stop valve, also called the interceptor valve, is the most widely used valve. It is popular because the friction between the sealing surfaces during opening and closing is small, it is relatively durable, the opening height is not large, it is easy to manufacture and maintain, and it is suitable not only for medium and low pressure, but also for high pressure. The closing principle of the stop valve is to rely on the pressure of the valve stem to make the valve disc sealing surface fit closely with the valve seat sealing surface to prevent the flow of medium.

[0003] The stop valve is installed on the side wall of the pipeline. The pipeline often needs to be bent when performing water supply and drainage work. In the existing technology, the pipeline is generally bent and then connected. The bending operation is relatively troublesome, or the pipeline is connected by setting a bending piece, and the two pipelines to be connected are fixed together using the bending piece. The bending piece is generally fixed by a flange, but the operation is troublesome when fixing with a flange, and it is inconvenient to fix and disassemble the pipeline. In addition, the sealing between the two connected pipelines is poor, which affects the water supply and drainage work of the pipeline. Utility Model Content
