The specific embodiment
Preferred embodiment below in conjunction with accompanying drawing 2-3 is described content of the present utility model, and the description of following examples only is exemplary and indicative, should any restriction not arranged to protection domain of the present utility model.
According to a kind of relay bi-pass quick-releasing combined valve of the present utility model, as Fig. 2, shown in Figure 3, its valve body K comprises hand valve interface 3, main valve interface 4, gas source interface 5, exhausr port 8, hand valve interface 3 separates by bilateral check valve valve 14 with the A chamber, the hand valve does not have glancing impact, pressurized air enters from hand valve interface 3, and bilateral check valve valve 14 can be sealed the A chamber in position shown in the solid line under pressure.
Described A chamber is set to vertically communicate with the C chamber, it is gradient and deep to the B chamber to have changed original A chamber, the problem that has processing difficulties, make the air pressure of main valve interface 4 be communicated to the A chamber again to the C chamber, described gas source interface 5 is communicated with the B chamber, the B chamber can arrive spring cylinder driving ante-chamber, and described exhausr port 8 is communicated with the D chamber.
Valve body K also comprises spring cylinder Parking back cavity interface 1 and 7, spring cylinder driving ante-chamber interface 2 and 6, relay valve valve 11, pull back spring 12, piston 13, described relay valve valve 11 outer described pull back spring 12, the pull back spring 12 employing coil springs of being arranged with.Described relay valve valve 11 tops are provided with piston 13, and piston 13 is motion up or down with the atmospheric pressure size variation in B chamber and C chamber, when it moves downward, can promote to open relay valve valve 11.
Described spring cylinder Parking back cavity interface 1,7 and main valve interface 4 all are positioned at described valve body K middle part, and spring cylinder driving ante-chamber interface 2,6 and gas source interface 5 all are positioned at described valve body K bottom, and described hand valve interface 3 is positioned at valve body K top.
Principle of work when specifically implementing automobile brake is as follows:
One, carry out braking during standstill, 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 pushed away in the position shown in the solid line, 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 outside the brake system from exhausr port 8, vehicle is braked, and can prevent to slide behind the vehicle parking.
Two, in driving, brake, 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, and piston 13 moves down opens relay valve valve 11, at this moment, gas source interface 5 air pressure enter the B chamber and arrive spring cylinder driving ante-chamber vehicle is braked.After removing the main valve braking, the C cavity pressure reduces, under the effect of B cavity pressure, and piston 13 upward movements, relay valve valve 11 is closed under the effect of pull back spring 12, makes from the air pressure of spring cylinder driving ante-chamber to discharge from exhausr port 8 through B chamber, D chamber.
Three, prevent double brake, realize that promptly braking during standstill is invalid when using service brake.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 arrive the A chamber again, shift bilateral check valve valve 14 onto dotted line position as shown in Figure 2, air pressure is removed braking during standstill through the F chamber from the E chamber behind spring cylinder Parking back cavity.
Embodiment recited above is described preferred implementation of the present utility model; be not that the utility model scope is limited; design under the spiritual prerequisite not breaking away from the utility model; various distortion and improvement that the common engineering staff in this area make the technical solution of the utility model all should fall in the definite protection domain of claims of the present utility model.
