Embodiment
In order that those skilled in the art more fully understands technical scheme, below in conjunction with accompanying drawing to this hair
It is bright to be further detailed.
It is that automatically controlled relay valve, including valve body 1 are used in a kind of gas braking provided in an embodiment of the present invention as shown in Fig. 2 to Fig. 6,
Wherein, the operation principle of valve body 1 is constant, changes the mode that compressed air enters controller 7, and the increase compensation of the inside of valve body 1 is logical
Road, is opened, and then cause inlet plenum 3 and the quick-make of discharge chamber 4, discharge chamber 4 using the air pressure control controller 7 of inlet plenum 3
It is connected with air chamber, air chamber is filled with, and after compressed air the friction plate on brake can produce with brake drum or brake disc friction
Raw brake force.
Specifically, in the present embodiment, there is control mouth 2 at the top of valve body, control mouth 2 is by air intake duct 5 with being located at
Controller 6 in valve body is connected；There is inlet plenum 3 and discharge chamber 4 in the bottom of valve body 1, controller 6 is used to control inlet plenum 3
With the connection of discharge chamber 4.
In the present embodiment, with reference to shown in Fig. 3 and Fig. 4, the top of valve body 1 is provided with solenoid electric valve 7, wherein, control
Mouth 2 and air intake duct 5 are connected with solenoid electric valve 7 respectively；Inlet plenum 3 be connected with solenoid electric valve 7 by compensating passage 5 and with
The composition compensation of air intake duct 5 loop, solenoid electric valve 7 is used for the unlatching for controlling compensation loop.That is, this programme is by setting
Compensate loop so that the gases at high pressure of inlet plenum 3 directly carry out action controller 6, and then shorten gas and enter control from control mouth
The stroke of device processed, improves the unlatching efficiency of controller, shortens the inflationtime of discharge chamber, and then shortens braking time,
Improve the security of vehicle.
Wherein, in the present embodiment, the unlatching acting as controlling compensation passage 8 of solenoid electric valve 7；Wherein, electromagnetism
Control valve 7 includes valve seat 71 and valve element 72 and magnet coil 73 in valve seat 71；One end of valve element 72 passes through spring compression
In the port of compensation passage 8, there is gap, to cause after energization, magnet coil 73 is produced between the other end and magnet coil 73
Magnetic force, so that valve element 72 causes compensation passage 8 to be opened to movement at compensation passage 8, compensation passage 8 independent role is realized
The unlatching of controller 6；Wherein, in the control circuit being externally connected to for controlling magnet coil to be powered of valve seat 71, this programme,
The bottom side of brake pedal is provided with the contact switch for controlling the control circuit turn-on, when stepping on brake pedal predeterminated position
When, contact switch is triggered, and controls circuit turn-on.
(in controller 6 no pressure, the no pressure of discharge chamber 4 output) is now in control mouth 2 and air intake duct 5 under off working state
Without air pressure, there is air pressure in inlet plenum 3 and compensation passage 8, valve element 72 compresses one end of compensation passage 8 in the presence of spring 74,
The air pressure in compensation passage 8 is set to cannot be introduced into controller.
Under working condition (controller works, and discharge chamber 4 has pressure output), brake pedal sets contact switch, and pedal is micro-
Dynamic i.e. controllable solenoid electric valve 7, which is powered, to be worked, and compensation passage 8 is separated with valve element 72 so that the air pressure of inlet plenum 3 is from compensation
Passage 8 enters controller 6, and by controller so that inlet plenum 3 is connected with discharge chamber 4, discharge chamber 4 sets up air pressure.When electromagnetism control
After valve 7 processed is powered off, the air pressure that valve element 72 is returned in off working state, controller 6 under the effect of spring 74 passes through the row of controller 6
Go out.
It should be noted that in the present embodiment, when solenoid electric valve 7 works, inlet plenum 3 is individually acted on, and it is used as gas
The direct drive control device 6 in source works.
Furthermore, it is understood that with reference to shown in Fig. 3 and Fig. 4, in the present embodiment, control mouth 2 passes through logical where magnet coil 73
Road is communicated with air intake duct 5, and solenoid electric valve 7 now there is control control mouth 2 to open and compensate the effect that passage 8 is closed simultaneously,
During work, the compensated passage 8 of gases at high pressure in control room 3 is individually flowed into be acted on controller 6 in controller 6, this
When, control mouth 2 is closed by the effect of magnet coil 73 and valve element 72, i.e. after energization, and valve element 72 is blocked in electromagnetism
At access port where coil 73, control mouth 2 is closed, and compensation loop is opened.Gases at high pressure in inlet plenum 3 are avoided from control
The risk that donsole 2 flows out is produced.Specifically, during work, valve element 72 is moved to left, and valve element 72 compresses one end of control mouth 2 so that gas
Pressure will not be flowed out from control mouth 2, and compensation passage 8 is separated with valve element 72 so that the air pressure in inlet plenum 3 enters discharge chamber 4, outlet
Air pressure is set up in room 4, so as to produce brake force by air chamber effect.
In such scheme, with reference to shown in Fig. 3, Fig. 5 and Fig. 6, spring 74 is arranged in valve seat 71 close to compensation passage 8
One end, when its is initial, coordinates the effect closure compensation passage 8 of valve element 72；Wherein, in valve element 72 outside one end of compensation passage 8
It is connected in catch 75, valve seat 71 and is provided with annular stop platform；Spring 74 is pressed between catch 75 and annular stop platform, with logical to compensation
Road 8 is blocked.Furthermore, it is understood that being convexly equipped with plug 76 respectively at the two ends of valve element, plug 76 is used to block at control mouth 2
The port of magnet coil and closure compensation passage 8, wherein, plug 76 is semicircular structure, and using it, it is respectively protruding into corresponding
Realize plugging action in port.
In addition, when magnetic valve does not work, controller 6 is controlled by control mouth 2, now, solenoid electric valve 7 is constantly in envelope
Under stifled state, this state, the structure of solenoid electric valve 7 is that chamber is provided with valve seat 71, and valve element 72 is slided in chamber, with reality
Now to the closure of compensation passage 8 and control mouth 2, wherein, valve element is to compensation access port direction close to one end of compensation passage
Raised tapered portion, spring is set in tapered portion, and the top of air intake duct is located at the bottom side of spring, to ensure air intake duct and valve element
Between have gap, it is ensured that air pressure smoothly flows into air intake duct；The outer wall of valve element 72, which is provided with along the glide direction of valve element 72, runs through valve element
72 grooves opened up；Valve element 72 is blocked when compensating passage 8, and the air-flow for flowing through control mouth 2 enters air intake duct through groove 77, passes through
Pyramidal structure valve element 72 is set to coordinate the effect of groove 77, it is ensured that when solenoid electric valve 7, which is damaged, not to work, from control mouth 2
The gases at high pressure of inflow smoothly can flow into air intake duct through valve element, and valve element 72 does not play inhibition.Now, control mouth 2 is individually made
With compensation loop does not work.
Some one exemplary embodiments of the present invention are only described by way of explanation above, undoubtedly, for ability
The those of ordinary skill in domain, without departing from the spirit and scope of the present invention, can be with a variety of modes to institute
The embodiment of description is modified.Therefore, above-mentioned accompanying drawing and description are inherently illustrative, should not be construed as to the present invention
The limitation of claims.
