Abstract: Provided is a reversing valve. The reversing valve includes: a main valve; a supporting frame having a first connecting end and a second connecting end, wherein the first connecting end is connected with the main valve, and an end wall of the first connecting end is attached to a side wall of the main valve; and a supporting structure located between a side wall of the first connecting end and the side wall of the main valve. Strength of connection between the main valve and the supporting frame of the reversing valve is high, thereby achieving safety and reliability.

Abstract: An electronic expansion valve, comprising a valve seat assembly and a valve core assembly. The valve core assembly is disposed in the valve seat assembly. The valve seat assembly comprises a valve seat, a valve seat core, and a guide sleeve. The valve seat is provided with a valve cavity, one end of which is open. A through hole is provided on the valve seat core; the end of the conduction portion close to the guide sleeve is circumferentially provided with an inclined surface inclined outwards. The valve core assembly comprises a valve head. The end of the valve head close to the valve seat core is provided with a sealing surface. The valve head is driven to move close to or away from the valve seat core, so as to adjust the gap between the inclined surface and the sealing surface.
