Background technology
Relay valve belongs to a part for automobile air brake brakes, and in the brakes of truck, relay valve plays contracting
Short reaction time and the effect of pressure settling time.In general, air inlet connects gas receiver to relay valve, and gas outlet connects system
Take offence room.When brake pedal, the output pressure of brake valve inputs as the control pressure of relay valve operation principle, is controlling
Under pressing pressure effect, intake valve is pushed open, then compressed air just directly enters brake chamber by gas receiver by air inlet, and
Without flowing through brake valve, this substantially reduces the loading line of brake chamber, accelerates the gas replenishment process of air chamber, realizes quick stop
Car.But current relay valve is distributed in the position residing for each wheel, due to longer, the long and narrow supply of the vehicle body of goods trailer
The air pressure that each relay valve is received in system can be different, and part especially nearer apart from headstock, air pressure is bigger, during brake
Brake force it is bigger, it may appear that vehicle body vibrations situation.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of relay valve that can prevent from producing bounce during brake.
In order to solve the above-mentioned technical problem, the utility model introduces a kind of servo that can prevent from producing bounce during brake
Valve, including：The housing of inner chamber is provided with, air inlet is provided with housing, is done if being additionally provided with to be connected with inner chamber on housing
Gas port, be additionally provided with the exhaust outlet being connected with inner chamber on housing, be provided with air inlet the through hole one that is connected with inner chamber and
Through hole two, spring is provided with air inlet, the seal one for matching with spring and sealing through hole one, be additionally provided with housing
The surge-chamber that air pressure in valve body is adjusted.
Further, axially hollow column liner is provided with exhaust outlet, exhaust outlet filtering is provided with exhaust port
Guard, spring is provided with liner, one end of spring is fixedly installed filtering screen.
Further, liner is internally provided with spring, and the end thereof contacts filtering screen of spring, the other end is provided with sealing
Part three, seal three are located at the connector of inner chamber and exhaust outlet.
Further, spring is provided with surge-chamber, be additionally provided with match with exhaust outlet and inner chamber interface channel it is close
Sealing two, one end of spring is in contact sealing exhaust outlet with seal two and inner chamber interface channel, the other end are provided with closure,
Seal two is used for sealing through hole two.
Further, the fixing device for being fixedly mounted is additionally provided with housing.
The utility model has the advantages that by being provided with surge-chamber in the valve body of relay valve, not only possess it is original after
The institute of dynamic valve is functional, and realizes the balance of each relay valve pressure in brake process, solves large-scale load truck and exists
The vehicle body caused by brake force difference shakes during skidding.

Embodiment
Embodiment cited by the utility model, it is only intended to help and understands the utility model, should not be construed as to this reality
With the restriction of novel protected scope, for those skilled in the art, the utility model thought is not being departed from
On the premise of, the utility model can also be made improvements and modifications, these are improved and modification also falls into the utility model right
In claimed scope.
As shown in Figures 1 to 7, the utility model describes a kind of relay valve that can prevent from producing bounce during brake, bag
Include：It is provided with the housing 1 of inner chamber 2；Air inlet 3 is provided with housing 1, the through hole being connected with inner chamber 2 is provided with air inlet 3
One 4 and through hole 25, spring 6 is provided with air inlet 3, the seal 1 for matching with spring 6 and sealing through hole 1；Shell
The surge-chamber 12 that air pressure in valve body is adjusted is additionally provided with body 1, spring 14 is provided with surge-chamber 12, be additionally provided with
The seal 2 15 that exhaust outlet 9 and the interface channel of inner chamber 2 match, one end of spring 14 are in contact sealing row with seal 2 15
Gas port 9 and the interface channel of inner chamber 2, the other end are provided with closure 13；Done if being additionally provided with housing 1 and being connected with inner chamber 2
Gas port 8, the exhaust outlet 9 being connected with inner chamber is additionally provided with housing 1, liner 10, filtering screen 11 are provided with exhaust outlet 9；
The fixing device 16 for being fixedly mounted is additionally provided with housing 1.
Air inlet 3 connects gas receiver, and gas outlet 8 connects brake chamber, when brake pedal, gas receiver output pressure
Into relay valve, through hole 25 is reached, when the timing of air pressure arrival one in relay valve, seal 2 15 is pushed open and reaches inner chamber 2, this
When, because valve body admission pressure rises, push seal 3 17 to liner so that air-flow can only flow to gas outlet 8, reach braking
Air chamber, realize the braking of vehicle.In brake process, because air supply system is long and narrow, it may appear that enter inside each relay valve
There is inconsistent situation in air pressure, and now, air pressure can be back to through hole 1 by inner chamber in the higher relay valve of pressure, push away
The backflow that seal 1 realizes excessive air pressure is opened, ensures that the air pressure in each relay valve is consistent, it is each which significantly improves vehicle
The situation that brake force differs between wheel.After completion is braked, gas receiver stops supply, and the pressure of air inlet 3 declines, gas outlet
8 pressure are higher than air inlet 3, and now, seal 3 17 is sealed inner chamber 2 by the extruding force of spring 18, and pressure passes through exhaust in valve body
Mouth 9 is discharged.
The utility model has the advantages that by being provided with surge-chamber in the valve body of relay valve, not only possess it is original after
The institute of dynamic valve is functional, and realizes the balance of each relay valve pressure in brake process, solves large-scale load truck and exists
The vehicle body caused by brake force difference shakes during skidding.
