Abstract
The utility model relates to a disc brake air exhausting device. The disc brake air exhausting device is characterized by comprising an air exhausting hose and an air bleeding one-way valve. A one-way valve capable of adjusting pressure is arranged at one end of the air exhausting hose, a needle valve is arranged at the other end of the air exhausting hose, and one end of the needle valve of the air exhausting hose is connected with the air bleeding one-way valve. The air bleeding one-way valve is provided with a protective cap. According to the disc brake air exhausting device, brake fluid is saved, labor intensity of maintenance personnel is reduced, the phenomenon that oil sprays to the faces of the maintenance personnel, safety of the maintenance personnel is guaranteed, and working environment pollution is reduced.
Description
Technical field
The utility model relates to a kind of venting gas appliance, specifically the disk type braker venting gas appliance.
Background technique
The air exhausting that needs behind the industrial wheeled equipment brake fluid line system overhaul to replenish in brake oil and the fluid that will brake removes, and exhaust is to carry out exhaust by the operation bleed valve.After need even stepping on several lower brake petals during discharging, slam again pedal and do not put, entered under the wheel by the maintenance man and with instrument bleed valve is screwed out, the oil circuit air directly is discharged into the air from bleed valve, thereby causes waste and the environmental pollution of brake fluid.Relatively poor because of engineering machinery construction operation environment, mud on brake disc, the break, grease adhere to more, and the easy corrosion of oil circuit bleed valve bolt causes part breaking, damage and causes waste when rotation venting one-way valve.Need to have the maintainer to operate bleed valve during exhaust, fluid can spray during exhaust oil circuit air, sprays fluid and is easy to be splashed to maintenance man's face.The maintenance man enters that also there is security hidden trouble in discharged air under the wheel under the diesel engine starting state.
Summary of the invention
The utility model is intended to overcome the defective of prior art, and a kind of disk type braker venting gas appliance is provided, and can save brake fluid, alleviates maintenance man's labor intensity, also avoids fluid to be ejected into maintenance man's face, has guaranteed maintenance man's safety; Can reduce operating environment pollutes.
In order to solve the problems of the technologies described above, the utility model is achieved in that
A kind of disk type braker venting gas appliance is characterized in that: it comprises an exhaust hose and a venting one-way valve, and an end of described exhaust hose is provided with the one-way valve of pressure-adjustable, and the other end is provided with needle-valve, and needle-valve one end of exhaust hose is connected with the venting one-way valve.
Described disk type braker venting gas appliance is characterized in that: described venting one-way valve is with protective cap.
The beneficial effects of the utility model are: can save brake fluid after the improvement, alleviate maintenance man's labor intensity, avoid fluid to be ejected into maintenance man's face, guarantee maintenance man's safety; And can reduce operating environment and pollute; The venting one-way valve has the nut protection, prevents that spool from adhering to mud, grease etc.Without air in the rotary check valve discharging oil circuit, the venting one-way valve is not fragile yet, reduces waste yet.During discharged air, fluid has been expelled back into the reservoir compartment.Avoided when discharged air fluid to spray and be splashed on the brake disc, thus the braking ability of the equipment of assurance.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1: disk type braker exhaust hose 3 is connected with venting one-way valve 1 on the brake cylinder with an end of needle-valve 2.Needle-valve 2 backs down venting one-way valve 1 in the connection procedure, the braking system oil circuit communicates with the discharged air pipeline, the other end at exhaust hose 3 is equipped with a pressure-adjustable one-way valve 4, is used for adjusting oil pressure, after air pipe line to be discharged is installed, can carry out bleeding, step on continuously several lower brake petals during exhaust, the air compressing that enters the braking system oil circuit is during to certain pressure, and oil is expelled back in the reservoir compartment by exhaust hose 3 with air, until the brake circuit air drains, finish exhaust process.
After air exhausting removes, remove exhaust hose 3, venting one-way valve 1 protective cap is screwed on, so that protection venting one-way valve 1 carries out same bleeding to remaining break.
Claims (2)
