[0010] As a further improvement of the utility model, the inner wall of the concave connection port is provided with a threaded groove, and the interior of the convex connection port is fixedly connected with a threaded connection pipe that matches the threaded groove.

[0011] As a further improvement of the utility model, two reinforcement rings are fixedly connected to the surface of the three-way pipe body, and a reinforcement rod is fixedly connected between the two reinforcement rings.

[0012] Beneficial effects of the utility model:

[0014] By setting a one-way structure and an anti-corrosion coating, when in use, after the one-way pipe and the three-way pipe body are connected, the liquid enters the one-way pipe from the three-way pipe body and flushes the check plate open. After the liquid is input, the check plate will return to the mounting ring under the action of the elastic wheel part, blocking the one-way pipe, so that the device can avoid liquid backflow, making the three-way pipe body safer to use. At the same time, the anti-corrosion coating can prevent the inside of the pipe from being corroded, thereby increasing the service life of the device. BRIEF DESCRIPTION OF THE DRAWINGS
