Description
Technical field
The present invention relates to the brake systems technology field of track passenger plane car, particularly a kind of dual pipe air supply device of rail locomotive.
Background technology
The brake system of rail locomotive is the critical component ensureing track traffic safety, and the wherein safety of brake system, reliability and stability are even more important.Wherein, the dual pipe air supply device of the brake system of rail locomotive controls.
The dual pipe air supply device of traditional rail locomotive comprises from main compressor, for airduct, train pipe, brake cabinet, first total reservoir and second total reservoir, wherein the two ends of first total reservoir are connected respectively with from main compressor with for airduct, the two ends of second total reservoir are connected with brake cabinet with for airduct respectively, brake cabinet one end is connected with second total reservoir, and the other end is connected with train pipe.Passenger locomotive is when without fiery loopback, and by hanging together car end train pipe, when carrying out dual pipe air supply effect for airduct, train tube pressure enters the total reservoir of locomotive second after pressure limiting, and its pressure keeps about 200kPa ~ 250kPa.Wind regime for airduct is about except the wind regime of 600kPa except providing for rear body, enters the total reservoir of locomotive second by the pipeline be communicated with.Because the pressure for airduct is about 600kPa, and the pressure of second total reservoir is required to be about 250kPa, the air duct pressure that supplies entering the total reservoir of locomotive second is made to cause second total reservoir pressure more than 250kPa, finally cause brake cylinder maximum pressure more than 250kPa, do not meet the requirement of iron mark TB/T 2056-2007 electric locomotive brake engineering factor, rail locomotive is lower without the safety of brake system during fiery loopback.
Therefore, how improving the safety of rail locomotive without brake system during fiery loopback, is those skilled in the art's technical matterss urgently to be resolved hurrily.
Summary of the invention
The object of this invention is to provide a kind of dual pipe air supply device of rail locomotive, this air supply device can improve the safety of rail locomotive without brake system during fiery loopback.
For achieving the above object, the invention provides a kind of dual pipe air supply device of rail locomotive, comprise from main compressor, for airduct, train pipe, brake cabinet, cut out cock, first total reservoir and second total reservoir, the two ends of first total reservoir are connected respectively with from main compressor with for airduct, the two ends of second total reservoir are connected with brake cabinet and cut out cock respectively, described cut out cock two ends respectively reservoir total with described second and the described airduct that supplies are connected, brake cabinet one end is connected with second total reservoir, the other end is connected with train pipe, when rail locomotive is without fiery loopback locomotive, described cut out cock is in closed condition.
In technique scheme, in the dual pipe air supply device of rail locomotive provided by the invention, because rail locomotive is as during without fiery loopback locomotive, cut out cock is in closed condition, intra-locomotive is led directly to for airduct, second total reservoir is as the braking reservoir without fiery loopback locomotive, its wind regime connects from power vehicle the train pipe hung, train tube pressure makes the pressure of second total reservoir be held in 200 ~ 250kPa after pressure limiting, second total reservoir is avoided to be subject to supplying the impact of air duct pressure, thus ensure that the maximum brake-cylinder pressure without fiery loopback locomotive is 200 ~ 250kPa, meet the requirement of iron mark TB/T2056-2007 electric locomotive brake engineering factor, guarantee locomotive operation safety.Therefore, the air supply device that the application provides can improve the safety of rail locomotive without brake system during fiery loopback.

Wherein in Fig. 1: the total reservoir of 1-brake cabinet, 2-second, 3-boiler check valve, 4-cut out cock, 5-train pipe, 6-are for airduct, 7-reflux valve, the total reservoir of 8-first.
Detailed description of the invention
Core of the present invention is to provide a kind of dual pipe air supply device of rail locomotive, and this air supply device can improve the safety of rail locomotive without brake system during fiery loopback.
In order to make those skilled in the art understand technical scheme of the present invention better, below in conjunction with drawings and embodiments, the present invention is described in further detail.
Please refer to Fig. 1, in a kind of detailed description of the invention, the dual pipe air supply device of rail locomotive provided by the invention comprises from main compressor, for airduct 6, train pipe 5, brake cabinet 1, cut out cock 4, boiler check valve 3, reflux valve 7, first total reservoir 8 and second total reservoir 2, the two ends of first total reservoir 8 are connected respectively with from main compressor with for airduct 6, the two ends of second total reservoir 2 are connected with brake cabinet 1 and cut out cock 4 respectively, cut out cock 4 two ends respectively reservoir 2 total with second and confession airduct 6 are connected, brake cabinet 1 one end is connected with second total reservoir 2, the other end is connected with train pipe 5, boiler check valve 3 and reflux valve 7 parallel connection, reservoir 2 total with second and cut out cock 4 are connected respectively at the two ends of boiler check valve 3, reservoir 2 total with second and cut out cock 4 are connected respectively at the two ends of reflux valve 7.When rail locomotive is without fiery loopback locomotive, cut out cock 4 is in closed condition.When rail locomotive is as power vehicle, cut out cock 4 is in open mode.Concrete, cut out cock 4 is arranged in the total reservoir 2 of air supply system second with on the pipeline that is connected and is connected with second total reservoir 2 afterwards of crossing for airduct 6.
