The valve body 21 is formed using aluminum alloy materials casting, its density is low, intensity is high, plasticity is good.
The operation principle of the antiskid valve of the present invention is as follows：
1. air inlet P11 and air inlet P41 air inlets, normally closed solenoid valve A no powers, normally closed solenoid valve A, which is in, at this time closes shape
State, normal open solenoid valve B no powers, at this time normal open solenoid valve B be in opening；Distinguished at this time by air inlet P41 into gas
The top of exhaust pition D by B air inlets 4, then can be reached by B delivery outlets 5 again, then inlet piston C is reached through gas channel 8
Lower section, realize inlet piston C open, gas by air inlet P11 flow through combination valve air inlet 9 again from delivery outlet P21 export；This
For energization inflated condition, this function controls the inflation boost function in antiskid valve work for the piston-type pressure of the present invention.
2. air inlet P11 and air inlet P41 air inlets, normally closed solenoid valve A is powered, and normally closed solenoid valve A is opened at this time, normal open
Solenoid valve B no powers, normal open solenoid valve B is nature open mode at this time.It can be led to respectively into air-flow by air inlet P41 at this time
A air inlets 1 are crossed, then reach the top of inlet piston C by A delivery outlets 2 again, then reach exhaust pition D's through gas channel 7
Lower section；Reached above exhaust pition D, then passed through by B delivery outlets 5 through B air inlets 4, again by the air-flow that enters of air inlet P41 at the same time
Gas channel 8 is reached below inlet piston C, and inlet piston C's and exhaust pition D has air pressure impact up and down at this time, due to work
The forced area of air pressure up and down of plug is different, and the top area of piston is more than lower section, therefore the power above and below gas shock is not
Equal, the power of top is higher than lower section, so inlet piston C can be moved downward at this time, closes combination valve air inlet 9, exhaust is lived
Plug D can be pushed, and close combination valve outlet 10, and gas is not inputted and also do not exported at this time, this is balance packing state.This work(
Can be the stabilization air pressure function in the antiskid valve work of the present invention.
3. air inlet P11 and donsole P41 air inlets, normally closed solenoid valve A is powered, and is opened at this time into normally closed solenoid valve A, normal open
Solenoid valve B is powered, and normal open solenoid valve B is closed at this time.Gas is entered respectively through A solenoid valves air inlet 1 by control mouth P41 at this time,
Then the top of inlet piston C is reached by A delivery outlets 2 again, then the lower section of exhaust pition C is reached through gas channel 7, at this time into
Gas piston C is moved downward, and closes combination valve air inlet 9, and exhaust pition D rises, and opens combination valve outlet 10, this is dropped for exhaust
Pressure condition.This function alleviates buck functionality for the exhaust in the antiskid valve work of the present invention.
4. air inlet P11 and control mouth P41 air inlets, normally closed solenoid valve A no powers, normally closed solenoid valve A closings at this time, often
Three-way electromagnetic valve B be powered, at this time normal open solenoid valve B close, by the gas of control mouth P41 rest on respectively A air inlets 1 and B into
Gas port 4, does not play the role of control, this is pass-through state.This function is directly to supply the qigong in the antiskid valve work of the present invention
Energy.
5. after normally closed solenoid valve A is powered off, the upper end of inlet piston C and the air-flow of airflow line 7 can be by A exhaust outlets 3
Arrange to air.
6. after normal open solenoid valve B is powered, the upper end of exhaust pition D and the air-flow of airflow line 8 can be by B exhaust outlets 6
Arrange to air.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
