The invention discloses a two-position four-way reversing valve for an automotive air conditioner, which is used for the technical field of air conditioning systems. The two-position four-way reversing valve comprises a valve body and a valve plug rotationally arranged in the valve body, wherein the valve body is internally provided with a high-pressure air inlet pipe connected with a compressor outlet, a low-pressure exhaust pipe connected with a compressor inlet, an evaporator pipe and a condenser pipe; the high-pressure air inlet pipe and the low-pressure exhaust pipe are located on the upper and lower sides respectively; two communicating ports of the evaporator pipe and two communicating ports of the condenser pipe are parallel to a communicating port of the high-pressure air inlet pipe and a communicating port of the low-pressure exhaust pipe respectively; a high-pressure air inlet side reversing structure and two low-pressure exhaust side reversing structures are arranged on the valve plug; the high-pressure air inlet side reversing structure is parallel to the communicating port of the high-pressure air inlet pipe; and the two low-pressure exhaust side reversing structures are parallel to the communicating port of the low-pressure exhaust pipe, and are arranged symmetrically relative to an axis of the valve plug. The two-position four-way reversing valve is simple and compact in structure, and can avoid an influence of vibration in an automobile running process on the working stability of the valve body.
Description
Technical field [0001] The invention relates to a reversing valve used in the technical field of air conditioning systems, in particular to a two-position four-way reversing valve for automobile air conditioning. Background technique [0002] The switching between cooling and heating of the automobile air conditioning heat pump system is accomplished through a four-way valve. Ordinary two-position four-way reversing valve may cause structural failure, jamming or leakage during the working process of automobile air conditioning system due to vibration. [0003] After searching the prior art, it was found that Chinese Patent Document No. CN201973324, publication date 2011-09-14, records a four-way valve for air conditioning, the valve body is provided with two sets of four through holes, and the valve core is provided in the valve body , The valve core is provided with two sets of channels, the valve core rotates, and the two sets of channels are respectively connected to two sets o...
