The valve body 10 has a valve cavity 101 and a communication port. The valve body 10 includes a side wall portion 11, a valve cover 13 and a bottom wall portion 12. Along the axial direction of the side wall portion 11, at least part of the side wall portion 11 is located between the bottom wall portion 12 and the valve cover 13. The side wall portion 11, the valve cover 13 and the bottom wall portion 12 define at least part of the valve cavity 101. At least part of the communication ports are located on the inner surface of the side wall portion 11. The valve cover 13 and the bottom wall portion 12 are both sealed and connected to the side wall portion 11. For example, one of the valve cover 13 and the bottom wall portion 12 is injection molded into an integral structure with the side wall portion 11, and the other is welded to the side wall portion 11 to achieve sealing. The valve cover 13, the bottom wall portion 12 and the side wall portion 11 can jointly define the valve cavity 101. At least part of the valve core 20 is located in the valve cavity 101 and the valve core 20 can rotate in the valve cavity 101. In the embodiment of the present invention, the bottom wall portion 12 and the side wall portion 11 are injection molded into an integral structure, and the valve cover 13 and the side wall portion 11 are limitedly arranged and welded and sealed.
