Description
Technical field
The utility model relates to locomotive brake control system field, refers in particular to the brake-cylinder pressure control system in the locomotive braking system.
Background technology
At present, domestic main line railway locomotive braking system mainly adopts DK-1 type brake system, and the brake-cylinder pressure of brake system is all exported by distributing valve.The pressure of brake cylinder equates with chamber volume pressure in the distributing valve.Big lock is the chamber volume pressure of Control Allocation valve indirectly; Little lock can the direct control distributing valve chamber volume pressure; Be the preparatory governor pressure of the indirect control brake cylinder of the big lock of DK-1 brake, the preparatory governor pressure of little lock direct control brake cylinder, the preparatory governor pressure of brake cylinder is chamber volume pressure.
Summary of the invention
For the control system that overcomes existing locomotive brake cylinder pressure can not realize Da Zha and the little lock deficiency to the separate control of preparatory governor pressure of brake cylinder; The utility model aims to provide a kind of system that relatively controls the locomotive brake-cylinder pressure; After the preparatory governor pressure of brake cylinder that this system produces big or small lock compared, adopting higher value was final brake-cylinder pressure.The preparatory governor pressure of brake cylinder that Jiang Dazha of this system and little lock produce separately; Do not communicate with each other between them, only relatively big or small each other through shuttle valve, after comparing; Become the control presssure of brake cylinder by the preparatory governor pressure of bigger brake cylinder, but the preparatory governor pressure of less brake cylinder exists still.
To achieve these goals, the technical scheme that the utility model adopted is:
A kind of system that relatively controls the locomotive brake-cylinder pressure; Its constructional feature is; Comprise shuttle valve and relay valve, the preparatory governor pressure of the brake cylinder that big lock produces links to each other with the admission port A1 of shuttle valve through admission line through behind electronic distribution valve and the electromagnetic valve, passes through admission line behind the preparatory governor pressure process of the brake cylinder of the little lock generation electronic distribution valve and links to each other with the admission port A3 of shuttle valve; The air extractor duct A2 of said shuttle valve links to each other with said relay valve through outlet pipe, and this relay valve links to each other with brake cylinder through pipeline.
The big preparatory governor pressure of lock brake cylinder is that the electronic distribution valve obtains according to big gate position, and the preparatory governor pressure of little lock brake cylinder is that the electronic distribution valve obtains according to little gate position.Through the setting of shuttle valve, make that the input of brake cylinder relay valve is the higher value in preparatory governor pressure of big lock brake cylinder and the preparatory governor pressure of little lock brake cylinder all the time, and big preparatory governor pressure of lock brake cylinder and all independently existence of the preparatory governor pressure of little lock brake cylinder.
By said structure; As shown in Figure 1; Shuttle valve 1 is unexistent in the present DK-1 brake system, utilizes the preparatory governor pressure of brake cylinder that preparatory governor pressure of brake cylinder that this shuttle valve can produce big lock and little lock produce separately, and admission line A1 is the preparatory governor pressure of big lock brake cylinder; Admission line A3 is the preparatory governor pressure of little lock brake cylinder, and outlet pipe A2 is two higher values in the preparatory governor pressure.When changing appearred in two preparatory governor pressure sizes, A2 pressure can conversion rapidly between A1 pressure and A3 pressure.Even the preparatory governor pressure of little lock brake cylinder is alleviated, because the existence of the preparatory governor pressure of big lock brake cylinder is arranged, the big preparatory governor pressure of lock brake cylinder can be exported to relay valve through shuttle valve rapidly, forms brake-cylinder pressure; Equally, even the preparatory governor pressure of big lock brake cylinder is alleviated, because the existence of the preparatory governor pressure of little lock brake cylinder is arranged, the big preparatory governor pressure of lock brake cylinder can be exported to relay valve through shuttle valve rapidly, forms brake-cylinder pressure.
Compared with prior art; The beneficial effect of the utility model is: through the utility model; Big preparatory governor pressure of lock brake cylinder and the preparatory governor pressure of little lock brake cylinder can independently separate, and can not influence each other, and to have only the preparatory governor pressure of bigger brake cylinder are final brake-cylinder pressures.
The control system of the utility model can solve:
1) locomotive can be through single slow electromagnetic valve, the brake-cylinder pressure that independent release produces because of the decompression of big lock control train pipe.
2) compare traditional preparatory governor pressure of big lock brake cylinder and the preparatory governor pressure of little lock brake cylinder is chamber volume pressure; Because big preparatory governor pressure of lock and the preparatory governor pressure of little lock are separate; Make big or small brake pressure when changing, the pressure of brake cylinder changes more rapidly thereupon, stablizes.
Below in conjunction with accompanying drawing and embodiment the utility model is done further to set forth.

The specific embodiment
A kind of system that relatively controls the locomotive brake-cylinder pressure; As shown in Figure 1; Comprise shuttle valve 1 and relay valve 2; The preparatory governor pressure of brake cylinder that big lock produces links to each other with the admission port A1 of shuttle valve 1 through admission line with single slow electromagnetic valve 4 backs through electronic distribution valve 3; Link to each other with the admission port A3 of shuttle valve 1 through admission line behind the preparatory governor pressure process of the brake cylinder that little lock the produces electronic distribution valve, the air extractor duct A2 of said shuttle valve 1 links to each other with said relay valve 2 through outlet pipe, and this relay valve 2 links to each other with brake cylinder 5 through pipeline.
The utility model utilizes shuttle valve 1 to isolate the preparatory governor pressure of brake cylinder that large and small lock produces.And give relay valve 2 as final brake-cylinder pressure with higher value.
During locomotive brake, big lock is because the preparatory governor pressure of brake cylinder that the decompression of train pipe produces outputs to the A1 mouth of shuttle valve, and the preparatory governor pressure of brake cylinder that little lock directly produces outputs to the A3 mouth of shuttle valve.A1 mouth and A3 mouth are separate, independently exist simultaneously so can guarantee preparatory governor pressure of big lock brake cylinder and the preparatory governor pressure of little lock brake cylinder.Through shuttle valve, big preparatory governor pressure of lock brake cylinder and the preparatory governor pressure of little lock brake cylinder can compare, and have only the preparatory governor pressure of bigger brake cylinder to export to relay valve through the A2 mouth of shuttle valve.Total wind is adjusted into the preparatory governor pressure of bigger brake cylinder through relay valve with brake-cylinder pressure.
Have only when the preparatory governor pressure of big lock brake cylinder and the preparatory governor pressure of little lock brake cylinder are all alleviated; The A2 mouth pressure of shuttle valve just can be alleviated; The brake-cylinder pressure of relay valve output could be alleviated, and has increased the safety of locomotive brake like this, for traffic safety provides more reliable guarantee.
