Abstract

The invention discloses a reversing device. The reversing device comprises a driven valve body and a driving valve body; the driving valve body comprises a first fixing part, a first through hole, a second through hole and a third through hole, wherein the first through hole, the second through hole and the third through hole are intersected with the first fixing part; the driven valve body comprises a second fixing part, a fourth through hole, a fifth through hole and a sixth through hole, wherein the fourth through hole, the fifth through hole and the sixth through hole are intersected withthe second fixing part; the reversing device further comprises a first groove and a second groove, and the first fixing part and the second fixing part are used for oppositely isolating and sealing the first groove and the second groove; the first through hole communicates with the fourth through hole through the first groove, the second through hole communicates with the sixth through hole through the second groove, and the third through hole communicates with the fifth through hole. According to the reversing device, the driven valve body and the driving valve body are relatively integratedwith each other, and is beneficial to improving the structural strength of the reversing device.

Description

【Technical field】 [0001] The invention relates to the technical field of control, in particular to a control device for controlling the flow direction of a medium. 【Background technique】 [0002] In the field of fluid control, it is often necessary to change the flow direction of the medium, and a reversing device is generally used to change the flow direction of the medium. At present, the pilot valve is a commonly used reversing device. The two valves of the pilot valve are usually connected by an external capillary. Compared with other structures of the pilot valve, the external capillary is relatively fragile and is easily damaged during transportation or installation. Therefore, it is necessary to improve the existing technology to solve the above technical problems. 【Content of invention】 [0003] The purpose of the present invention is to provide a relatively integrated reversing device to improve the structural strength of the product. [0004] In order to achiev...
