Adjustor of braking relay valve

Abstract

The invention relates to an adjustor of a braking relay valve. The adjustor is mainly characterized in that: a big air cylinder, a small air cylinder and a valve installing hole are sequentially arranged inside a cylinder body, a spacing clamp spring is arranged on a corresponding position of the interior of the big air cylinder; an adjusting and controlling pore path, which is penetrated through the big air cylinder and the valve installing hole, is arranged on an entity position of the small air cylinder; a small convex cylindrical piston, which is slightly longer than the small air cylinder, is fixedly arranged under the big piston; an adjusting spring, an adjusting and compressing member and an adjusting screw are arranged on the small convex cylindrical piston; venting pore paths, which are communicated, are arranged in the centers of the big piston and the small piston; the air cylinder body at the middle lower part of the adjusting and controlling pore path is provided with an adjusting and controlling pore path connecting hole which is communicated with the adjusting and controlling pore path, and connecting holes which are communicated with the small air cylinder in a staggering way; and vent holes are arranged on an air cylinder cover. The adjustor of the braking relay valve has the advantages of capability of automatically adjusting the braking air pressure of the braking relay valve, firm braking of a loaded car and firm emergent braking, good rapid braking effect, capability of decelerating stably during empting and light braking, no premature locking, reduction of 'taking-off', side-slipping and gnawing badly between tires and the ground, wide application range, safety, reliability and obvious social benefits.

Description

technical field [0001] The invention relates to a relay valve regulator, in particular to a brake relay valve regulator. Background technique [0002] The existing brake relay valve regulators all correspond to the brake relay valves one by one, that is, a brake relay valve regulator can only be used on a brake relay valve, and cannot be adjusted according to the brake relay valve. The dynamic air pressure is differently adjusted and used; therefore, the use is single and the range is narrow. In particular, the brake air pressure of the brake relay valve cannot be automatically adjusted according to empty vehicles, light brakes, heavy vehicles, sudden brakes, etc. Serious slippage, heavy vehicles or sudden brakes are not firm, the braking distance is long, the fast braking effect is poor, and safety cannot be guaranteed. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a brake relay valve adjuster which c...
