Technical Field

The invention relates to the technical field of three-way valves, in particular to a high-temperature flue gas double-valve-plate integrated air-sealing three-way baffle valve.

Background

The three-way valve has three ports, one inlet and two outlets, (left inlet, right outlet and lower outlet) and is different from the common valve in that the bottom of the three-way valve is provided with an outlet, when the inner valve core is at different positions, the outlets are different, if the valve core is at the lower part, the left outlet is connected with the right outlet, if the valve core is at the upper part, the right outlet is blocked, and the left outlet is connected with the lower outlet. Because the left and right ports are not in a horizontal line. When the high-pressure emergency is disconnected, the valve is closed, water is fed away from the bypass, high-temperature smoke of the common three-way valve is easy to leak, and the maintenance is troublesome.
