The invention discloses a reversing valve and a manufacturing method thereof. The reversing valve comprises a valve body assembly and a driving assembly. The valve body assembly comprises a valve body, a valve seat and connection pipes. The valve seat comprises a platelike body. The two side walls of the platelike body are provided with mounting faces matched with the inner wall of the valve body.The platelike body is connected to the inner wall of the valve body in an abutting manner through the mounting faces. A gap is formed between the lower end face of the platelike body and the inner wall of the valve body. The platelike body is further provided with mounting holes, wherein the mounting holes are formed in the thickness direction of the platelike body. The connection pipes extend into the mounting holes and are fixed to the valve body. According to the reversing valve, the platelike body of the valve seat can be made of a plate material; compared with a D-shaped bar material adopted in the prior art, the plate material is low in price; in the mounting hole machining process, the platelike body can be fixed only through common locating components; and the manufacturing process is simpler.
Description
technical field [0001] The invention relates to the technical field of refrigeration system flow path control, in particular to a reversing valve and a preparation method thereof. Background technique [0002] At present, reversing valves are usually used in air conditioning systems to switch between cooling and heating functions. Figure 11 It is a schematic diagram of a typical reversing valve structure and control method. [0003] The reversing valve includes a valve body assembly 100 and a driving assembly 200 , and the reversing valve controls the movement of the driving assembly 200 by changing the fluid pressure of the control component 300 to switch the flow path. [0004] Among them, the E connection, S connection and C connection of the reversing valve are all fixed to the valve body through the valve seat, and the valve body is usually a circular cylindrical structure. The joint surface is preferably a circular arc surface matched with the inner wall of the valve...
