Abstract

The invention relates to a self-operated three-way reversing valve, and belongs to the technical field of fluid control valves. The valve comprises a valve body, a valve cap, a valve core, a spring and the like, wherein the valve body is dislocatedly provided with an evaporator connecting pipe and a condenser connecting pipe perpendicular to an axis of the valve body; a distance L1 between the shaft axis of the evaporator connecting pipe and the shaft axis of the condenser connecting pipe is greater than the sum of the inner radius of the evaporator connecting pipe and the inner radius of the condenser connecting pipe; and the valve cap is provided with an air exhaust connecting pipe of a compressor. The valve adopts simple structures of the spring and the valve core, and realizes effective switching without additional power by using the elasticity of the spring, and differential pressure change generated by switching on and switching off of the refrigeration compressor in an air conditioning unit. The valve has the advantages of simple structure, few consumed material and low manufacturing cost, and can effectively improve energy saving effect and reliability of a heat pipe and vapor compression compound refrigeration air conditioning unit.

Description

technical field [0001] The invention belongs to the technical field of fluid control valves, in particular to a self-operated three-way reversing valve specially used for heat pipe and vapor compression combined refrigeration and air-conditioning units. Background technique [0002] Most of the existing automatic reversing valves have an electromagnetic or pneumatic pilot valve, which relies on the pilot valve to provide power to change the channel flow direction of the main valve. Sex is not ideal either. Contents of the invention [0003] The invention provides a self-operated three-way reversing valve, which can not only realize reliable switching without additional power, ensure the effective sealing of the valve port, but also have a simpler structure, so that the heat pipe and vapor compression composite refrigeration and air conditioning unit have better energy saving effect and higher reliability. [0004] Technical scheme of the present invention is as follows: ...
