Description
Technical field
The utility model belongs to rail vehicle compressed air delivery device field, is specifically related to a kind of safe-guard system for subway vehicle compressed air delivery.
Background technique
Existing subway vehicle project organization, its pressurized air respectively saving between compartment is only used a flexible pipe to connect and carries, but there is certain potential safety hazard in this design, because on the compressed air line of whole single-line series, the breaking of any one section of flexible pipe all can cause the pressurized air cannot be to the transmission of follow-up compartment, the air pressure simultaneously causing because of gas leakage declines and also can cause the malfunctioning of the atmospheric controls such as door contact interrupter, skidding, thereby affect the normal operation of subway vehicle, even cause security incident.
Model utility content
In order to solve existing subway vehicle, respectively save the single-line series structure that the pressurized air between compartment is only used a flexible pipe to connect and carry, the breaking of any one section of flexible pipe all can cause the pressurized air cannot be to the transmission of follow-up compartment, the air pressure simultaneously causing because of gas leakage declines and also can cause the malfunctioning of the atmospheric controls such as door contact interrupter, skidding, thereby affect the normal operation of subway vehicle, the technical problem that even causes security incident, the utility model provides a kind of safe-guard system for subway vehicle compressed air delivery.
The technological scheme that the utility model technical solution problem is taked is as follows:
Safe-guard system for subway vehicle compressed air delivery comprises a plurality of safety convenience instruments, each safety convenience instrument correspondence is arranged on a joint compartment of vehicle, each safety convenience instrument comprises two flexible pipe switch protecting valves, suction tude, the first steam outlet pipe and second steam outlet pipe, one end of suction tude is connected with the gas holder air outlet in this section compartment, and the other end is connected with the suction port of two flexible pipe switch protecting valves; One end of described the first steam outlet pipe and the second steam outlet pipe is connected with an air outlet of two flexible pipe switch protecting valves respectively, and their the other end is connected with the suction port of the same gas holder of next joint in adjacent compartment.
The beneficial effects of the utility model are: should be for the safe-guard system of subway vehicle compressed air delivery; it arranges two flexible pipe switch protecting valves respectively by the two ends at every joint railway car; and connect and close on the gas holder on two joint compartments with two flexible pipes, and then all form two train compressed air delivery paths in parallel between every two joint compartments.When a certain steam outlet pipe on the two flexible pipe paths between compartment causes pressure drop because of breakage gas leakage; two flexible pipe switch protecting valves cut out and open another path by the less pipeline of pressure automatically; thereby ensured that vehicle compressed air conveying system is unaffected; greatly reduce and because of air leak in hose, cause the malfunctioning probability of failures of atmospheric control such as door contact interrupter, skidding, thereby ensured the normal operation of subway vehicle.
Accompanying drawing explanation
Fig. 1 is that the utility model is for the structural representation of a safety convenience instrument of the safe-guard system of subway vehicle compressed air delivery;
Fig. 2 is that the utility model is for the application principle figure of the safe-guard system of subway vehicle compressed air delivery.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details.
As depicted in figs. 1 and 2; the utility model comprises for the safe-guard system of subway vehicle compressed air delivery: a plurality of safety convenience instruments; each safety convenience instrument correspondence is arranged on a joint compartment of vehicle; each safety convenience instrument comprises a two flexible pipe switch protecting valve 1, suction tude 2, the first steam outlet pipe 3 and second steam outlet pipe 4; one end of suction tude 2 is connected with the gas holder air outlet in this section compartment, and the other end is connected with the suction port of two flexible pipe switch protecting valves 1.One end of the first steam outlet pipe 3 and the second steam outlet pipe 4 is connected with an air outlet of two flexible pipe switch protecting valves 1 respectively, and their the other end is connected with the suction port of the same gas holder of next joint in adjacent compartment.
When concrete application the utility model is used for the safe-guard system of subway vehicle compressed air delivery, select the AB839-T7 type automatic transfer valve of Faville Lay company (Faiveley) production as two flexible pipe switch protecting valves (double hose protection valve).Two flexible pipe switch protecting valves 1 are set respectively at the two ends in the every joint of subway vehicle compartment; the suction port of the two flexible pipe switch protecting valves 1 in first joint compartment is directly connected with the gas holder of air compressor by suction tude 2; the air outlet of this pair of flexible pipe switch protecting valve 1 is connected with the second steam outlet pipe 4 with the first steam outlet pipe 3 respectively; the first steam outlet pipe 3 and the second steam outlet pipe 4 are connected with the suction port of same gas holder in second section compartment, and form thus two train compressed air delivery paths in parallel.And gas holder in second section compartment is re-used as the compressed air supplies of next joint compartment gas holder, by that analogy.Gas holder is used to the pneumatic element in its compartment, place that pressurized air is provided.
When two flexible pipe switch protecting valves 1 pour pressurized air by suction tude 2 at first, the spring piston in its valve body can connect and close simultaneously by a larger steam outlet pipe of pressure the steam outlet pipe that another pressure is less automatically.When the steam outlet pipe of originally connecting on the two flexible pipe paths between compartment causes pressure drop because of breakage gas leakage; the spring piston of two flexible pipe switch protecting valves 1 can be because of the variation auto-action of internal differential pressure; the pipeline that pressure is less is closed; and automatically open another path; thereby continue to have ensured that vehicle compressed air conveying system is unaffected; vehicle is normally moved, reduce vehicle trouble rate.
