As above-mentioned scheme feature, for the two operating consoles that in the locomotive control chamber, are provided with, can reach by 2 automatic brake valves by above-mentioned braking transfer valve, control the purpose of a cover relay valve and equalizing reservoir.
Above-mentioned inside at valve pocket, the plunger valve that can reciprocatingly slide to the both sides end cap, the groove of can cut off, conducting is different is to realize connecting different connecting lines.
For improving that pressure air is linked up and airtight performance during the dissengaged positions switching in the braking transfer valve, can be between valve pocket and valve body, be provided with and be used for leak free O type circle.Outer setting at plunger valve has several to be used for leak free O type circle.
For realizing that 2 operating consoles control an identical cover relay valve and an equalizing reservoir via same braking transfer valve, described braking transfer valve connects 2 brake activation valves and 1 relay valve and 1 equalizing reservoir respectively.Wherein,
Between valve pocket and valve body, be provided with 9 annular through groove, include the equalizing reservoir pipe that connects equalizing reservoir, connect relay valve in all pipe and total wind shut-off valve tube, and connect in 2 equalizing reservoir pipes of 2 brake activation valves, 2 brake activation valves all pipe and 2 the total wind blocking of brake activation valve pipes respectively.
Further refinement scheme is, 2 equalizing reservoir pipes are arranged on two ends of valve body, the equalizing reservoir pipe that connects equalizing reservoir is arranged on the midway location of valve body, equal both sides of pipe during all pipe is separately positioned in 2 brake activation valves, and 2 the total wind blocking of brake activation valve pipes are arranged on the both sides of total wind shut-off valve tube.
Between two operating consoles of locomotive cab, adopt above-mentioned braking transfer valve, can realize the method that a kind of operation state of locomotive switches.Particularly,
2 brake activation valves that are provided with in the locomotive control chamber connect a braking transfer valve respectively.
The braking transfer valve connects relay valve and equalizing reservoir.
Relay valve is connected with the train pipe, connects the wind regime of locomotive simultaneously by blast main.
The pressure at both sides of control brake transfer valve inner post plug valve is poor, with the connecting line of communication or cut-out and 2 brake activation valves, realizes that the operation state of indoor 2 brake activation valves of trainman switches.When one of them brake activation valve be in conducting state and the braking of controlling locomotive when alleviating, another brake activation valve is in dissengaged positions.Thereby realize switching between 2 operating consoles and control same set of relay valve and equalizing reservoir.
When one of them brake activation valve control relay valve and equalizing reservoir in-to-in pressure variation, another brake activation valve is cut off with the pipeline of braking transfer valve.
The operation brake activation valve is regulated air pressure in the equalizing reservoir, and the flow gain by relay valve outputs to the air pressure of train pipe with control, and then implements the braking or the alleviation of train.
In addition, connect the equalizing reservoir of braking transfer valve, the air pressure fluctuation in can balanced described equalizing reservoir pipe.
As above content, described braking transfer valve and realize that the method that operation state of locomotive switches has the following advantages:
1, need not to change existing braking principle of work and locomotive air pipeline structure, can automatically carry out operation state at the control cabin that is provided with two operating consoles and switch, maneuverability pattern directly, effectively;
2, the installation quantity and the space of brake component be can save, the maintenance and the maintenance of system unit made things convenient for.
