Abstract

The invention provides a four-way reversing valve and an air-conditioner. The four-way reversing valve comprises a valve body, a valve core, matching pipes and capillary tubes, wherein the valve body is provided with an inner cavity; the valve core is arranged inside the inner cavity and divides the inner cavity into three separate cavities, and the three cavities are sequentially arranged in the axial direction of the valve body and comprise the first adjusting cavity, the second adjusting cavity and the communicating cavity arranged between the first adjusting cavity and the second adjusting cavity; the matching pipes are communicated with the communicating cavity and comprise the first matching pipe, the second matching pipe, the third matching pipe and the fourth matching pipe; the capillary tubes comprise the first capillary tube and the second capillary tube, the first capillary tube is connected between the first adjusting cavity and the first matching pipe, the second capillary tube is connected between the second adjusting cavity and the second matching pipe, the valve core is provided with a first position and a second position, the first position enables the first matching pipe to be communicated with the third matching pipe and enables the second matching pipe to be communicated with the fourth matching pipe, and the second position enables the first matching pipe to be communicated with the fourth matching pipe and enables the second matching pipe to be communicated with the third matching pipe. The low-pressure end and the high-pressure end of the four-way reversing valve can be interchanged.

Description

technical field [0001] The invention relates to the technical field of reversing valves, in particular to a four-way reversing valve and an air conditioner provided with the four-way reversing valve. Background technique [0002] In the prior art, the four-way reversing valve used in refrigeration and air-conditioning systems is an electromagnetic reversing valve. The high-pressure side of the system is connected to the low-pressure side, and the piston is driven to move through the pressure difference, thereby realizing commutation. [0003] The existing four-way reversing valve is widely used in heat pump air-conditioning systems, but it also has the following disadvantages: [0004] 1. The high pressure end of the four-way reversing valve is fixed, that is, it can only be used according to the specified connection method, and the high and low pressure sides cannot be interchanged. [0005] 2. When the four-way reversing valve is used for flow path switching and high-pre...
