Abstract
The utility model discloses a novel visual oil return check valve which comprises an upper valve body and a lower valve body. A first blind hole is formed in the upper end of the upper valve body and a second blind hole is formed in the lower end of the lower valve body. The second blind hole is an oil inlet. The upper valve body is tightly clamped with the lower valve body through a pin and the edges of the connecting portions of the upper valve body and the lower valve body are provided with connecting hanging lugs respectively. The two hanging lugs are fixedly connected through a screw. The upper valve body and the lower valve body are provided with an upper oil outlet pipe communicated with the first blind hole and a lower oil outlet pipe communicated with the second blind hole respectively. The upper oil outlet pipe and the lower oil outlet pipe are communicated through a transparent C-shaped pipe or a transparent U-shaped pipe. The novel visual oil return check valve has the advantages that the structure is simple, oil can be observed through the transparent C-shaped pipe or the transparent U-shaped pipe when oil return is conducted through the oil return check valve, great convenience is brought for a serviceman, and practicality is high.
