The specific embodiment
Below in conjunction with Fig. 1-4 explanation preferred embodiment of the present utility model.Fig. 1 is for adopting the braking schematic diagram of gas circuit of relay bi-pass quick-releasing combined valve of the present utility model.As shown in Figure 1, during normal vehicle operation, give spring cylinder Parking back cavity 520 air feed by relay bi-pass quick-releasing combined valve 300, make spring cylinder Parking back cavity spring be in compressive state (brake off state) always from the gas that hand valve 100 is come.And main valve 200 does not have pressure gas output, and spring cylinder ante-chamber 520 does not have pressurized air at this moment, can not produce brake action to vehicle.
During braking during standstill, when hand valve 100 is operated appointed positions, the admission port of hand valve 100 is closed, the residual gas of air extractor duct is discharged from exhausr port, and the gas of spring cylinder Parking back cavity 520 is discharged from relay bi-pass quick-releasing combined valve 300, spring cylinder Parking back cavity compression spring discharges, and this moment, vehicle was in braking during standstill.
During service brake, step on main valve 200 pedals earlier, the piston of main valve 200 air extractor duct gas pressures in the relay bi-pass quick-releasing combined valve 300 is opened admission port, and the pressurized air of source of the gas 400 enters spring cylinder driving chamber 510, brakes.
If service brake and braking during standstill are done the time spent simultaneously, under the gas pressure of main valve 200, the pressurized air of source of the gas 400 enters in the unidirectional valve pocket of bilateral of combine valve 300 upper valve bodies, and hand valve 100 does not have air pressure output at this moment, so can enter spring cylinder back cavity 520 by the bilateral check valve, thereby the releasing braking during standstill reaches the effect that prevents double brake.
As shown in Figure 2, in a preferred embodiment of relay bi-pass quick-releasing combined valve of the present utility model, comprise upper valve body 10, middle valve body 20, following valve body 30 and erecting frame 40, upper valve body 10 has the function of bilateral check valve, middle valve body 20 has the function of rapid release valve, following valve body 30 has the function of relay valve, and upper valve body 10, middle valve body 20 are connected to down on the valve body 30 successively, and following valve body 30 is connected on the erecting frame 40.This combine valve is combined into a valve with bilateral check valve of the prior art, rapid release valve, relay valve, and volume only is equivalent to the size of a common relay valve.Relay bi-pass quick-releasing combined valve of the present utility model has not only been saved installing space and has been reduced the entrucking space, has reduced cost of product, but also simplified the pipeline installation, simplified manufacturing, assembly process.Simultaneously,, improved the sensitivity of driving and Parking, realized adopting the function of a combine valve control driving ante-chamber and Parking back cavity because the pipeline of having cancelled between the former valve body connects.
Fig. 3 represents the annexation of relay bi-pass quick-releasing combined valve of the present utility model in gas circuit.As shown in Figure 3, this relay bi-pass quick-releasing combined valve comprises spring cylinder Parking back cavity interface 1 and 7, spring cylinder driving ante- chamber interface 2 and 6, hand valve interface 3, main valve interface 4 and gas source interface 5.Suddenly dying when the hand valve can't glancing impact, and the gas in the following valve body 30 (being equivalent to relay valve) can promptly be supplied with in the valve in one's hands by upper valve body 10 (being equivalent to the bilateral check valve), prevent the generation of traffic accident effectively.
Fig. 4 is the fundamental diagram of a preferred embodiment of relay bi-pass quick-releasing combined valve of the present utility model, and the principle of work of this combine valve is as follows:
One, Parking: the hand valve does not have glancing impact, and pressurized air enters from hand valve interface 3, under pressure bilateral check valve valve 14 is promoted solid line position as shown in Figure 3, the A chamber is sealed, this moment air pressure from the E chamber through the F chamber to spring cylinder Parking back cavity.When hand valve glancing impact, hand valve interface 3 does not have air pressure, the air pressure of spring cylinder Parking back cavity through the F chamber, the D chamber is discharged to atmosphere from exhausr port 8, vehicle is braked, in case slide behind the vehicle parking.
Two, driving: when main valve carries out glancing impact, the air pressure of main valve enters into the C chamber through main valve interface 4 and promotes piston 13, piston 13 moves down opens relay valve valve 11, and at this moment, gas source interface 5 air pressure enter B chamber arrival spring cylinder driving ante-chamber vehicle is braked.After removing the main valve braking, the C cavity pressure reduces, and under the effect of B cavity pressure, piston 13 is up, and relay valve valve 11 is closed under pull back spring 12 effects, makes from the air pressure of spring cylinder driving ante-chamber to discharge from exhausr port 8 through B chamber, D chamber.
Three, after the hand valve is braked, when wanting brake off to find that the hand valve does not have air pressure, can step on main valve.Pressurized air is entered into the C chamber through main valve interface 4 promote piston 13, piston 13 moves down opens relay valve valve 11, at this moment, gas source interface 5 air pressure enter the B chamber, the air pressure in B chamber passes to the A chamber, shift bilateral check valve valve 14 onto dotted line position as shown in the figure, air pressure is removed braking during standstill through the F chamber from the E chamber behind spring cylinder Parking back cavity.
Only being the explanation of the utility model preferred embodiment below, is not the restriction to the utility model itself.The utility model is not limited to specific embodiment disclosed herein, and is limited by claim.In addition, various other different embodiment of disclosed embodiment and various distortion will become apparent to those skilled in the art that these all embodiment, change and distortion all comprise within the scope of the claims.
