Problems solved by technology

However, there will inevitably be some impurities in the system. Once the impurities in the system enter the fitting gap, it may cause impurities to be embedded in the matching parts of the valve core part and the valve body part, resulting in the failure consequence of not being able to rotate and being stuck.

Abstract

The invention discloses a rotary reversing valve, comprising a valve core part, the valve core part comprising a valve core with a first flow channel and a second flow channel, the first flow channel is in the circumferential direction of the valve core Two first valve port portions are formed on the outer edge portion, and two second valve port portions are formed on the peripheral outer edge portion of the valve core for the second flow passage, and the first valve port portion and the The circumferential outer edge portion opposite to the second valve port portion is provided with an axial accommodating groove, and further includes an axial sealing component, the axial sealing component includes an elastic member and a sealing member, and the elastic member is placed in the In the accommodating groove, the sealing member is placed in the accommodating groove and partially protrudes from the peripheral outer edge. The rotary reversing valve disclosed in the present invention can improve the impurity compatibility of the product, and make the valve core and the valve body Not easy to get stuck between.

Description

technical field [0001] The invention relates to the technical field of refrigeration system control, in particular to a rotary reversing valve. Background technique [0002] In the refrigeration system, the reversing valve is generally used to realize the conversion function of cooling and heating. At present, with the development of the industry, large-scale refrigeration equipment is also continuously used in the refrigeration industry. The requirement for the refrigerating capacity of the reversing valve is also increasing, which requires the volume of the reversing valve product to be larger, so the rotary reversing valve with a larger structure is mostly used to switch the cooling / heating function of the system. [0003] figure 1 It is a schematic structural diagram of a rotary reversing valve used in a refrigeration system in the background art. like figure 1 shown. The refrigeration system includes a compressor 200 , a first heat exchanger 300 , a rotary reversin...
