Embodiment Construction

[0028] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0029] As described in the background technology, the electric four-way valve uses a motor to drive the piston to rotate 90 degrees clockwise or counterclockwise to guide the flow of hot air from the compressor in the air conditioner. The hot air discharged from the compressor enters the outdoor unit through the reversing valve, and the outdoor is hot and the indoor is cold, which is summer cooling mode; after the piston rotates 90 degrees, the hot air enters the indoor unit through the reversing valve, and the indoor is hot and the outdoor is cold, which is winter cooling mode. heat mode. However, the current electric four-way valve needs to install a large gearbox outside the valve body, res...

Abstract

The invention provides a reversing valve. The reversing valve comprises a valve body and a valve core rotationally installed in the valve body, wherein a plurality of passages are arranged on the valve body; two of the passages can be selectively communicated by rotating the valve core; the reversing valve further comprises a driving part and a transmission part, wherein the driving part is arranged on the valve body and comprises at least one output part, and a plurality of first transmission structures are arranged in the circumferential direction of the output part; and the transmission part is fixed to the end of the valve core, the transmission part and the valve core are coaxially arranged, a plurality of second transmission structures are arranged at the inner side or the outer side of the transmission part in the circumferential direction, and power of the output part of the driving part can be transmitted to the valve core through the cooperation of the first transmission structures and the second transmission structures. The passages can be selected by controlling the rotating angle of the transmission part, mechanisms such as a speed reducer do not need to be arranged outside the valve body, and the reversing valve is simpler in structure and easy to install.

Description

technical field [0001] The invention relates to the technical field of reversing valve equipment, in particular to a reversing valve. Background technique [0002] At present, most of the piston-type four-way reversing valves use pneumatic control for the piston, which leads to the fact that it must rely on the gas pressure of the air conditioner to work. If the air conditioner is not turned on, or the pressure does not meet the requirements, the four-way valve will not work normally. [0003] The electric four-way valve uses a motor to drive the piston to rotate 90 degrees clockwise or counterclockwise to guide the flow of hot gas from the compressor in the air conditioner. The hot air discharged from the compressor enters the outdoor unit through the reversing valve, and the outdoor is hot and the indoor is cold, which is summer cooling mode; after the piston rotates 90 degrees, the hot air enters the indoor unit through the reversing valve, and the indoor is hot and the ...
