Description

Technical Field

[0001] The utility model relates to the technical field of brake control valve bodies, in particular to a brake control valve body. Background Art

[0002] The control valve body in the automobile brake is an important component used to connect the brake rod and the brake drum in the automobile brake, and it plays a very important role in the braking process of the brake; Patent No. CN202021711185.4 discloses a new type of automobile brake control valve body, which uses a connecting rod and a piston to not only facilitate the connection of the brake rod, but also prevents the brake rod from being worn under the action of the piston; however, when the connecting rod moves, it will drive the piston to slide in the first valve chamber and generate high heat due to friction. Although coolant is used for cooling, the piston will also suffer certain losses during the sliding friction process. When the loss is large, it needs to be replaced, and the piston located in the first valve chamber is quite inconvenient to replace. To this end, we propose a brake control valve body. Utility Model Content

[0003] In view of the problems in the prior art, the utility model provides a brake control valve body.

[0004] The technical solution adopted by the utility model to solve the technical problem is a brake control valve body, including a valve body, a threaded hole is opened on the top surface of the valve body, and a sliding cavity connected to the threaded hole is preset inside the valve body, a rotating seat for limiting is screwed on the inside of the threaded hole, and a vertical shaft located inside the sliding cavity is slidably installed inside the rotating seat, and a piston slidably connected to the sliding cavity is sleeved on the outer periphery of the vertical shaft;

[0005] A sponge sleeve matching the vertical axis is mounted on the inner side of the rotating seat, and a rubber sleeve matching the vertical axis is mounted on one end of the inner wall of the sliding cavity away from the rotating seat.

[0006] By adopting the above technical solution, when the control valve body for brake application is used, the top of the vertical shaft can be connected to the brake rod, and the vertical shaft can slide and displace the piston in the sliding cavity inside the valve body as the brake rod drives the piston. At the same time, when the piston is greatly worn, the rotary seat in the threaded hole at the top of the valve body can be rotated so that the rotary seat and the threaded hole are screwed and separated from each other, which is convenient for disassembly of the rotary seat, thereby facilitating disassembly of the vertical shaft, and the piston on the outer periphery of the vertical shaft can be disassembled and replaced, and the replacement is simple and convenient.

[0007] When the control valve body is in use, the vertical shaft can fit with the sponge sleeve on the inner periphery of the rotary seat, so as to reduce the infiltration of dust and debris into the sliding cavity from the gap between the rotary seat and the vertical shaft. At the same time, the rubber sleeve at the bottom opening of the sliding cavity can protect the vertical shaft and reduce the damage caused by friction between the vertical shaft and the inner wall of the bottom opening of the sliding cavity, so that the vertical shaft can operate more stably.

[0008] Specifically, a spiral groove is arranged inside the valve body, and a pipe bending seat connected to the spiral groove is threadedly installed on the outer peripheral surface of the valve body, and there are two groups of pipe bending seats.

[0009] By adopting the above technical solution, the spiral groove facilitates the entry of coolant, and the elbow seat facilitates the diversion of the coolant, so that the coolant for cooling flows along the spiral groove and cools the inner side of the valve body.

[0010] Specifically, a ring groove is provided between the threaded hole and the rotating seat, and there are multiple groups of ring grooves, and a rubber ring is clamped and installed inside the ring groove.

[0011] By adopting the above technical solution, the rubber ring is located inside the ring groove, which is convenient for improving the stability of the rotary seat being screwed into the threaded hole.

[0012] Specifically, a rubber ring is bonded to the bottom surface of the rotary seat, and a transverse groove for rotation is opened on the outer peripheral surface of the rotary seat, and there are multiple groups of transverse grooves.

[0013] By adopting the above technical solution, the multiple groups of transverse grooves on the outer periphery of the rotary seat make it easier to disassemble and assemble the rotary seat, and the rubber ring is convenient for improving the tightness of the rotary seat and the threaded hole after being screwed together.

[0014] Specifically, the outer peripheral surface of the valve body is integrally formed with inclined plates, and there are multiple groups of inclined plates.

[0015] By adopting the above technical solution, the inclined plate can easily improve the strength of the valve body, so that the valve body can be used more stably.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The technical solution of the present application adopts the design of a sliding cavity, a threaded hole, a rotating seat, a vertical shaft and a piston. When the control valve body for brake braking is used, the top of the vertical shaft can be connected to the brake rod, and the vertical shaft can slide and displace the piston in the sliding cavity inside the valve body as the brake rod drives the piston. At the same time, when the piston is severely worn, the rotating seat in the threaded hole on the top of the valve body can be rotated so that the rotating seat and the threaded hole are screwed together and separated, which is convenient for disassembly of the rotating seat, thereby facilitating disassembly of the vertical shaft, and the piston on the outer periphery of the vertical shaft can be disassembled and replaced, and the replacement is simple and convenient.

[0018] 2. The technical solution of the present application uses the design of a sponge sleeve and a rubber ring. When the control valve body is used, the vertical shaft can fit with the sponge sleeve on the inner circumference of the rotary seat, thereby reducing the infiltration of dust and debris into the sliding cavity from the gap between the rotary seat and the vertical shaft. At the same time, the rubber sleeve at the bottom opening of the sliding cavity is convenient for protecting the vertical shaft and reducing the damage caused by friction between the vertical shaft and the inner wall of the bottom opening of the sliding cavity, so that the vertical shaft can operate more stably.
