Problems solved by technology

[0002] In pneumatic gear control devices or pneumatic brake devices, seven-way valves and multi-way check valves of other specifications are often used. In the process of pneumatic control, the moisture in the air will be trapped in the control tube due to the change of external temperature. On the road, the accumulation of water will directly affect the accuracy of gear shifting, that is, jumping gears or disengaging gears. During the braking process, it will affect the braking effect, that is, brake failure and other consequences, which will seriously affect the safety of the vehicle. sex

Abstract

The invention discloses a seven-way valve which comprises a valve body and seven connectors. The valve body comprises an upper valve block (11) and a lower valve block (12). A ventilation groove (13) is formed in the middle portion of the lower valve block (12), and the ventilation groove (13) and all the seven connectors are through. A transition hole (14) is formed in one side of the ventilation groove (13). One end of the transition hole (14) is communicated with the ventilation groove (13), and the other end of the transition hole (14) is communicated with a water storage groove (15). An opening is formed in the part, at one end of the water storage groove (15), on the valve body, and a plug (3) is arranged in the opening. According to the seven-way valve, the transition hole and the water storage groove are formed in the valve body, and thus the gas conveying distance is increased; on the basis that air pressure transmission is not influenced, moisture in air in the valve body can be attached to a groove wall and can be discharged out of the valve body through the opening of the water storage groove; and the seven-way valve is simple and practical in structure, convenient and rapid to operate and wide in application range.
