Problems solved by technology
Most semi-trailer vehicles use pneumatic brake valves to control the braking of the vehicle. Since the traditional brake valve adopts a closed structure, there has been a problem of internal water accumulation during the use of the brake valve for a long time, and the brake valve needs to be disassembled and cleaned from time to time. Accumulated water causes inconvenience to the operation of the vehicle, especially in winter when the temperature is low and the accumulated water freezes and the vehicle cannot operate

Embodiment Construction
[0017] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings:
[0018] Such as figure 1 , 2 As shown, the trailer brake valve drainage device includes a valve cover 11 and a valve body 9. The control intake and exhaust ports 12 of the valve cover 11 are connected to a drainage device. The drainage device consists of a casing, a return spring 7 and a piston body that moves along the inner wall of the casing. 3, the shell is composed of the front shell 1 and the end cover 8. The piston body 3 and the return spring 7 are located in the shell, and the return spring 7 is fixed on the end cover 8. The diameter of the middle section of the piston body is smaller than the diameter of both ends , The front end of the shell is provided with a brake gas inlet 1, and the side wall is provided with an exhaust port 6 and a brake valve communication port 4. The brake valve communication port 4 is closely connected with the control ...

The invention belongs to the field of brake valves, and more particularly relates to a seeper-proof trailer brake valve, which comprises a valve cover and a valve body, wherein a drainage device is connected to an air intake and exhaust control port; the drainage device comprises a shell, a reset spring and a piston body moving along the inner wall of the shell; the front end of the shell is provided with a braking air inlet; the lateral wall of the shell is provided with an exhaust port and a braking valve communicating port; the braking valve communicating port is closely connected with theair intake and exhaust control port; the piston body and the reset spring are positioned in the shell; the reset spring is fixed at the tail end of the shell; the diameter of the middle section of the piston body is less than the diameters of two ends of the piston body; and the piston body, the lateral wall of the shell and the braking valve communicating port and the exhaust port on the lateralwall of the shell jointly form an air guide channel. By arranging the drainage device at the air intake and exhaust control port of the trailer brake valve, seeper in the brake valve can be automatically drained to ensure safe and convenient running of vehicles; and because a heating device is arranged on the valve body, the brake valve can be ensured not to generate ice barrier in cold winter through heating.
Description
Technical field [0001] The invention relates to a brake valve for an anti-water trailer, belonging to the field of brake valves. Background technique [0002] In recent years, with the continuous development of my country's automobile industry, long-distance transportation vehicles have become a development trend, especially semi-trailer vehicles occupy most of the freight market. Most semi-trailer vehicles use pneumatic brake valves to control the braking of the vehicle. Because the traditional brake valve adopts a closed structure, there has been a problem of internal water accumulation during the use of the brake valve for a long time. The accumulation of water causes inconvenience to the operation of the vehicle, especially in the winter when the temperature is low, the accumulation of water and ice make the vehicle unable to operate. Summary of the invention [0003] Based on the above shortcomings in the prior art, the technical problem to be solved by the present invention...
