Cone core rotary customized 4 way reversing valve, including the main valve body and valve cover, the inlet and outlet pipes on the main valve body, and the reversing movable parts in the main valve body controlled by the pilot valve. Its characteristics are: The valve body is a barrel type, and its inner cavity is a conical cavity. The center of the Y-shaped pipeline is provided with a U-shaped cavity connecting the three outer ports of the Y-shaped pipeline on the side wall of the middle of the valve core, and a half moon-shaped cavity is opened on the other side wall of the middle of the valve core opposite to the U-shaped cavity. The inlet and outlet pipes and the two reversing liquid pipes are arranged on the side wall of the main valve body, and the four pilot valve capillaries are respectively connected to the main valve body inlet and outlet pipes and the main valve cover corresponding to the cavity on the top surface of the valve core. The valve body has fewer parts, compact structure, no complicated welding and other processing techniques, simple processing and assembly, good sealing performance, improved production efficiency, and reduced cost.
The above is a brief introduction to the basic knowledge of the cone core rotating customized 4 way reversing valve.
