Specific embodiment
Embodiments of the present invention are illustrated by particular specific embodiment below, those skilled in the art can be taken off by this specification
The content of dew understands other advantages of the invention and effect easily.
It should be clear that structure, ratio, size depicted in this specification institute accompanying drawings etc., is only used to coordinate disclosed in specification
Content, so that those skilled in the art understands and reads, is not limited to enforceable qualifications of the invention, therefore do not have
Technical essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size are not influenceing institute's energy of the present invention
Under effect of generation and the purpose to be reached, all should still fall in the range of disclosed technology contents to be covered.
Meanwhile, in this specification it is cited such as " on ", D score, "left", "right", the use of " centre " and " one "
Language, is merely convenient to understanding for narration, and be not used to limit enforceable scope of the invention, and its relativeness is altered or modified,
Under without essence change technology contents, when being also considered as enforceable category of the invention.
As depicted in figs. 1 and 2, the present invention provides a kind of hydraulic brake system for embracing tank car, including：Controller is (in figure
It is not shown), and braking valve group 1, relay valve 2, pressure-reducing valve 3 and brake cylinder group 4, described braking valve group 1, relay valve
2nd, pressure-reducing valve 3 and brake cylinder group 4 are sequentially connected by main line 8, and operationally, hydraulic pressure is 75bar in main line 8.
