Problems solved by technology
[0002] Four-way valves and multi-way valves of other specifications are often used in pneumatic gear control devices or pneumatic brake devices. In the process of pneumatic control, the moisture in the air will be trapped in the control pipeline due to the change of external temperature. , the accumulation of water will directly affect the accuracy of shifting, that is, jumping or disengaging, and the braking effect will be affected during the braking process, that is, brake failure and other consequences, which will seriously affect the safety of the vehicle.

Embodiment Construction
[0016] The present invention will be further described below in conjunction with accompanying drawing.
[0017] like figure 1 and figure 2 As shown, the present invention is made up of valve body 1 and four interface 2 etc., and described valve body 1 is rectangular, and the upper and lower end faces of described valve body 1 are respectively provided with two interfaces 2, and the middle part of described valve body 1 A strip-shaped vent hole 3 is provided, and the two ports 2 on the upper end surface of the valve body 1 are arranged diagonally to the two ports 2 on the lower end face. The lower ends of the two ports 2 on the end face are connected through;
[0018] On the two sides of the valve body 1 corresponding to the position of the vent hole 3, there are two observation ports 4 that match the shape of the corresponding position of the vent hole 3, and the two observation ports 4 are connected through the vent hole 3. , the axial center line of the vent hole 3 is on...

The invention discloses a four-way valve. The four-way valve comprises a valve body (1) and four connecting openings (2), wherein the upper end surface and the lower end surface of the valve body (1) are each provided with two connecting openings (2); a ventilation hole (3) is formed in the middle of the valve body (1); two observation openings (4) are symmetrically formed in the two sides of the valve body (1) and both connected and communicated with the ventilation hole (3); the bottom and the top of the ventilation hole (3) are each provided with a water storage tank (5), one end of each water storage tank (5) is provided with an opening in the valve body (1), and each opening is provided with a plug (6). The ventilation hole and the water storage tanks are arranged in the valve body, the air conveying distance is prolonged, water of the air in the valve body is collected in the water storage tanks on the basis of not affecting pneumatic transmission and discharged out of the valve body through the openings of the water storage tanks, and the four-way valve is simple and practical in structure, convenient and rapid to operate and wide in application range.
Description
technical field [0001] The invention relates to the technical field of valve manufacturing, in particular to a four-way valve. Background technique [0002] Four-way valves and multi-way valves of other specifications are often used in pneumatic gear control devices or pneumatic brake devices. In the process of pneumatic control, the moisture in the air will be trapped in the control pipeline due to the change of external temperature. The accumulation of water will directly affect the accuracy of shifting, that is, jumping or disengaging, and the braking effect will be affected during the braking process, that is, brake failure and other consequences, which will seriously affect the safety of the vehicle. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a four-way valve capable of removing moisture in the air. [0004] Technical scheme of the present invention is as follows: [0005] A four-way valve, comprising...
