Problems solved by technology
[0005] 1. When the compressed air from the air inlet acts on the spool, the spool needs to move down a certain distance to work on the brake valve body, and in different environments, the movement stroke of the spool is the same, so it cannot be adjusted according to the vehicle Adjust the response speed required in the actual use process, resulting in advance or delay
[0006] 2. The intake pressure cannot be adjusted, and the brake valve cannot be protected when the compressed air is unstable
[0007] 3. In an emergency, the pipeline of the air inlet is damaged, and when the compressed air at the air inlet is reduced or zero, the braking operation cannot be carried out. The traditional emergency braking will affect the tires of the vehicle.

The invention relates to the field of automobile control and discloses a multifunctional anti-waterlogging brake valve for a trailer. A control device (2) is arranged at an air inlet and outlet end ofa valve body of the brake valve (10). The control device (2) comprises the valve body (27). A first valve cavity (21) is arranged inside the valve body (27). A main valve core (24) is arranged insidethe first valve cavity (21). The position of the main valve core (24) is limited by a limit rod (26) which penetrates through the main valve core. When in use, the multifunctional anti-waterlogging brake valve for the trailer can not only perform the function of draining water collected inside the brake valve, but also adjust the response speed of the brake valve. In the actual use process, the multifunctional anti-waterlogging brake valve for the trailer controls inlet air pressure in order to enable the control to be more stable and prevent the brake valve from being locked up due to excessive pressure, and the multifunctional anti-waterlogging brake valve for the trailer is provided with an unloading valve for stable control of compressed air entering the interior of the brake valve inorder to ensure the stability of the inlet air pressure.
Description
technical field [0001] The invention relates to the field of automobile control, in particular to a multifunctional anti-water braking valve for trailers. Background technique [0002] In recent years, with the rapid development of the national economy and modern industry, road transportation has become increasingly busy. With the construction of modern basic roads, the scope of transportation business continues to expand, and transportation in remote plateau areas is also increasing. In order to increase the transportation volume, the length of the semi-trailer is continuously increasing. In order to make the transportation of the vehicle safe and efficient and reduce the accident rate, higher requirements are put forward for the braking system of the transportation vehicle. [0003] Most of the brake valves in the prior art adopt a closed structure, and there has been an internal water supply problem for a long time, and it is necessary to disassemble the brake valve from...
