The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate valve is sealed by the contact between the valve seat and the gate disc. Usually, the sealing surface will be welded with metal materials to increase wear resistance, such as cladding 1Cr13, STL6, stainless steel, etc. The gate disc has rigid gate disc and elastic gate disc. According to the different gate discs, the gate valve is divided into rigid gate valve and elastic gate valve.

[0009] Optionally, a fixing tube is inserted into the other side of the mounting tube, and a mounting ring is fixedly connected to one side of the surface of the fixing tube.

[0010] Optionally, a sealing ring is fixedly connected to the edge of the top surface of the threaded hole, and a waterproof coating is applied to the surface of the sealing ring.

[0011] Optionally, a circular block is fixedly connected to the top of the screw, and an anti-slip film is attached to the outer surface of the circular block.

[0012] The utility model provides a gate valve that is easy to install and has the following beneficial effects:

[0013] 1. The gate valve is easy to install. Through the arrangement of the clamping assembly, the installation cylinder and the connecting pipe, when personnel need to install the external water pipe, the external water pipe can be placed inside the connecting pipe. Then the personnel can slide the fixing ring backward to squeeze its spring. Then when the personnel place the external pipe inside the connecting pipe, the personnel can loosen the fixing ring, so that its spring drives the fixing ring to place the clamping bead on the surface of the external pipe, thereby facilitating the personnel to quickly fix the external pipe.

[0014] 2. The gate valve is easy to install. Through the arrangement of the installation cylinder, screw and valve core, when personnel need to open the valve core inside the installation cylinder, personnel can turn the screw to drive the valve core to open the inside of the installation cylinder.
