Description of drawings
Accompanying drawing is a pipeline structure schematic representation of the present utility model
1 is three-position five-way hand-operated direction valve II among the figure, the 7th, and the manual solenoid directional control valve II of two-position three way band, the 5th, three-position five-way hand-operated direction valve I, the 3rd, the manual solenoid directional control valve I of two-position three way band.
Embodiment
A kind of gas braking integrated valve,
Three-position five-way hand-operated direction valve I (3) has O1, P1, A1, M1, five pipe joints of N1, three-position five-way hand-operated direction valve II (1) has O2, P2, A2, M2, five pipe joints of N2, P1, P2 pipe joint all link to each other with source of the gas, the A1 pipe joint is connected with the active chamber I of stopping brake by service pipe I, and the A2 pipe joint is connected with the active chamber II of stopping brake by service pipe II.O1, O2 all are communicated with atmosphere by pipeline.
The manual solenoid directional control valve I of two-position three way band (5) has J1, K1, three pipe joints of L1, and L1 is connected with atmosphere with pipeline, is relief opening.The same respectively M1 of K1, J1, N1 are connected.The manual solenoid directional control valve II of two-position three way band (7) has J2, K2, three pipe joints of L2; L2 is connected with atmosphere, is relief opening.The same respectively M2 of K2, J2, N2 are connected.
Three-position five-way hand-operated direction valve I (3) spool is in first working position, three-position five-way hand-operated direction valve II (1) spool is in second working position, P1 and A1 are communicated with, O1, M1, N1 all end, O2 and A2 are communicated with, and P2, M2, N2 all end, this moment source of the gas from service pipe I to the active chamber I of stopping brake inner inflatable, to outside exhaust, gas promotes the braking of stopping brake internal piston to active chamber II by service pipe II.This is for realizing manual braking.
Three-position five-way hand-operated direction valve I (3) spool is in second working position, three-position five-way hand-operated direction valve II (1) spool is in first working position, A1 and O1 are communicated with, P1, M1, N1 end, and P2 and A2 are communicated with, and O2, M2, N2 end, at this moment, to the active chamber II of stopping brake inner inflatable, to outside exhaust, gas promotes the involution of stopping brake internal piston to active chamber I to source of the gas by service pipe I from service pipe II.This is for realizing manual involution.
