Description
Technical field
The utility model belongs to the brake system of car parts and makes the field, relates to a kind of automobile-used pressure balance type automatic drain valve specifically.
Background technology
Commercial car adopts the braking of pressurized air pneumatic mode usually, and the automobile blow off valve is contained on automobile air receiver or the gas tank device usually, and each air receiver is equipped with the blow off valve device, is loaded on the bottom of air receiver.The design of traditional blow off valve is fairly simple, is provided with the check valve of a band draw ring, need be under the effect of manpower, draw back the check valve blowdown that discharges water of could working, and can not realize that air receiver discharges water automatically.Temperature decline round the clock makes condensed water more, makes the effective volume of each air receiver descend, and causes the brake system decrease in efficiency.Automobile usually because the reason that does not in time discharge water causes each circuit efficiency of brake system to descend, will have influence on brake system normal operation and vehicle safety travel during travelling.
The utility model content
At above-mentioned defective, the utility model provides a kind of automobile-used pressure balance type automatic drain valve, can carry out draining to the automobile air receiver automatically and discharge water, and compact conformation, connection mode are simple, easy for installation, greatly improve the reliability of brake system, prolonged the service life of brake system.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of automobile-used pressure balance type automatic drain valve, comprise valve body, described valve body is provided with outside thread, captives joint with the air receiver assembly, thread end is offered notch, in O-ring seals is set; Valve body lower portion arranges axial discharge port, is connected with the endoporus of valve body, and the endoporus of valve body arranges the spool of T font, between valve body inner bore end face and spool lower surface inner seal ring is set, and the top middle portion of valve body is provided with projection; On the described spool Sealing formboard is set, on seal cover cap is set, between seal cover cap and Sealing formboard air storage chamber is arranged, be connected by tracheae with air receiver assembly volume exocoel; Described valve body is provided with negative thread, captives joint by screw thread with interior cylinder, between interior cylinder and valve body seal ring is set; Interior cylinder lower end arranges the turnover tracheae, and the inner chamber of cylinder and valve body communicate with body cavity between spool, Sealing formboard, the seal cover cap in making; The described plug that arranges in interior cylinder upper end, interior cylinder perimembranous upper end arranges valve shell, and the lower end arranges filtering net.
Further, between valve body outside thread and the gas storage assembly, seal with sealant between valve body negative thread and interior cylinder.
Further, described discharge port is trumpet-shaped discharge port.
Further, described valve shell is nylon outer shell.
Further, described interior cylinder forms with nylon, nylon 66, plastics, PA11 or PA6 compacting.
Further, described spool processes with aluminum alloy or forms with PA6 die casting.
Further, described filtering net is the copper filtering net.
Further, described sealing lamina membranacea is that rubber plate is stamped to form.
Automobile-used pressure balance type automatic drain valve of the present utility model is installed in the automobile air receiver assembly inner chamber, is loaded on the original manual blow off valve of the interior replacement of nut of the moving blow off valve of the original-pack tennis partner of automobile air receiver.Valve body is provided with outside thread, captives joint with the nut of manual blow off valve, and engine-driven Air compressor is at first imported wet main storage tank with pressurized air through check valve.Pressurized air is handled through air dryer and is entered each air receiver of double loop then, when air pressure reaches certain value, the air receiver compressed air moves down through filtering net promotion sealing lamina membranacea and the spool of automatic drain valve, the compression drying air enters in the inner chamber between the spool, Sealing formboard, seal cover cap of automatic drain valve, make the outer cavity pressure of automatic drain valve chamber pressure and air receiver assembly keep balance, this is the inflation pressure equilibrium stage.
When pressurized air after the air dryer drying, enter air receiver assembly volume exocoel, under gas pressure, air receiver assembly volume exocoel air pressure keeps balance, and with interior cylinder in equilibrium of pressure.
When automobile touches on the brake braking, the air receiver internal pressure descends rapidly, automatic drain valve body cavity and interior cylinder inner chamber air pressure thereof then are higher than the outer cavity pressure of air receiver volume, at this moment air pressure backs down the sealing lamina membranacea, under the effect of air pressure, the feasible condensed water that is deposited in the air receiver bottom is discharged from the spool discharge port rapidly.
When air receiver assembly volume exocoel air pressure was lower than the rated pressure value, the compression drying air entered air receiver assembly volume exocoel again, automatic drain valve body cavity and interior cylinder inner chamber, and balance again keep-ups pressure.
Whenever automobile again during drag, produce the draught head of air receiver assembly volume exocoel and interior cylinder again, make air pressure back down the sealing lamina membranacea, the body cavity condensed water is discharged the little discharge port in the middle of spool rapidly under pressure, air inlet is carried out in circulation, equilibrium of pressure, brake (exhaust), drainage works automatically.Thereby each air receiver can not accumulate condensed water is not arranged, the ability of draining the water away reaches 100%.Automatic drain valve compact conformation of the present utility model, connection mode are simple, easy for installation, have greatly improved the reliability of brake system, prolong the service life of brake system.
