A first medium inlet 12 is provided in the bottom wall of the valve body 1 in the direction of the central axis of the valve stem mounting hole 11. And a first medium outlet 13 and a second medium outlet 14 are arranged on the left side wall and the right side wall of the valve body 1 along the direction orthogonal to the central axis of the valve rod mounting hole 11 and distributed and communicated with the first liquid outlet pipe and the second liquid outlet pipe. A transition chamber 15 is provided in the valve body 1 directly below the valve stem mounting hole 11. The valve core 3 is supported and sealed by the valve seat 4 and is integrally arranged in the transition cavity 15. The valve rod 2 is inserted on the top wall of the valve core 3.
