Abstract

The invention discloses a reversing valve and a manufacturing method thereof. The reversing valve comprises a valve body part and a sliding block part. The valve body part comprises a valve seat, a valve body and a connecting pipe. The reversing valve is characterized in that the valve seat comprises a valve seat body, the valve seat body is provided with flat plate segments which are connected mutually and used for matching with the sliding block part in a sliding mode and circular arc segments for connecting with the valve body, and the flat plate segments and the circular arc segments are enclosed to form a hollow cavity body. According to the reversing valve provided by the invention, the hollow cavity body is formed in the valve seat body, the overall amount of material using of the valve seat is effectively reduced, so that cost of materials is reduced; and the gold processing allowance of the hollow cavity body is less, a connecting pipe hole on the valve seat body is convenientto process, and the processing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of flow path control, in particular to a reversing valve and a manufacturing method thereof. Background technique [0002] In the current air conditioning system, a reversing valve is used to realize the conversion function of cooling and heating, and the reversing valve has a part called a valve seat. [0003] However, the valve seat is a D-shaped solid bar structure processed by metal rods (such as brass rods). The nozzle hole is installed in the valve seat. Among them, the amount of brass material is relatively large, which makes the material cost of the valve seat relatively high. Brass has relatively large heat transfer losses. Moreover, the connecting pipe hole needs to penetrate through the D-shaped solid bar as a whole, and the metal processing allowance is relatively large, which increases the processing cost of the valve seat. [0004] Therefore, how to reduce material cost and processing cost ...
