Background

The three-way sealing valve is a valve device with a valve body provided with three ports, one inlet and two outlets. The three-way sealing valve is different from a common valve in that an outlet is arranged at the bottom, when the inner valve core is at different positions, the outlet is different, if the valve core is at the lower part, the left and the right are communicated, if the valve core is at the upper part, the right outlet is blocked, and the left and the lower are communicated. Because the left and right ports are not in a horizontal line. When high-pressure emergency disconnection occurs, the valve is closed, and water is fed to a bypass. The three-way sealing valve used for low-pressure pipelines, especially vacuum, ventilation, low-pressure water pipe switching and other places at present mainly comprises a ball valve, a butterfly valve, a baffle valve and the like. However, these conventional three-way sealing valves have certain drawbacks. For example, ball valves require more material and are therefore more costly to manufacture. In addition, since the sealing area is large, the operation force is large during switching, and it is difficult to manufacture a large valve. And the butterfly valve and the baffle valve both need two to control the two-way switching of the three-way pipe. In order to overcome the above-mentioned drawbacks of the known three-way sealing valves, the present invention proposes a new type of three-way sealing valve.
