Abstract

The invention provides a four-way valve used for an R32 refrigerant, and an air conditioner. The four-way valve comprises a main valve body and multiple connecting pipes, a valve chamber is arranged in the main valve body, a valve core is arranged in the valve chamber, divides two ends of the valve chamber into a first valve chamber and a second valve chamber which are mutually independent, and comprises a valve seat and a slider, the slider is slidably arranged on the valve seat which is fixed on the main valve body, the connecting pipes are communicated with the valve chamber of the main valve body and include a connecting pipe E, a connecting pipe S, a connecting pipe C and a connecting pipe D, the inner diameter of each of the connecting pipe E, the connecting pipe S and the connecting pipe C is between 5.0mm and 7.0mm, and the inner diameter of the connecting pipe D is between 3.2mm and 5.5mm. By the four-way valve, the problem of internal leakage of four-way valves in the prior art can be effectively solved.

Description

technical field [0001] The invention relates to the field of connection technology, in particular to a four-way valve for R32 refrigerant and an air conditioner with the four-way valve. Background technique [0002] In the prior art, the outer diameter of the main valve body of the four-way valve is more than 20 millimeters, the inner diameter of the E, S, and C connecting pipes is more than 7.5 millimeters, and the inner diameter of the D connecting pipe is more than 6 millimeters. These dimensions are set by the existing It is determined by the condensing agent R22 and R410a used. However, when using environmentally friendly refrigerants with a small molecular weight such as R32, because the distance between the E, S, and C connecting pipes of the current four-way valve is too large, the size of the valve core in the main valve body is too large, causing the valve core to be in contact with the refrigerant. If the contact area of ​​the main valve body is too large, intern...
