Abstract
The invention discloses a dustproof exhaust pipe for a brake valve. The dustproof exhaust pipe comprises a straight pipe and a protective cylinder, one end of the straight pipe is communicated with an air outlet of the brake valve, the other end of the straight pipe is communicated with the protective cylinder, an exhaust port is radially formed in the protective cylinder, a block piece is arranged at the end of the straight pipe correspondingly communicated with the protective cylinder, one side of the block piece is hinged to the end of the straight pipe, and the straight pipe is separated from the protective cylinder by the block piece in a natural state. The exhaust pipe unidirectionally exhausts by arranging an inclined surface and the block piece on the straight pipe, the brake valve is prevented from sucking dust through the exhaust port in application, the straight pipe is fastened by a directional nut, and the exhaust port of the protective cylinder is constantly downward. The dustproof exhaust pipe is ingenious in structure, the performance of the existing brake valve is not affected, the exhaust direction of the brake valve is ensured, and the dust is stopped from entering a brake valve body from the exhaust port of the brake valve.
Description
Technical field
The present invention relates to dustproof freeing pipe for a kind of brake activation valve.
Background technology
Railway brake valve exhaust path has been communicated with exhausr port and brake activation valve inside, and sand and dust can enter brake activation valve inside through exhaust channel, affects the brake activation valve performance and even makes brake activation valve lose efficacy.The railway brake valve outlet can be divided into two kinds: straight-through exhausr port and dustproof exhausr port.Straight-through exhausr port is without any dustproof construction, and sand and dust can enter in brake activation valve; Dustproof exhausr port generally has rubber pad to prevent dust and two kinds of structures of partial metallurgy filter dirt sheet, and rubber pad is yielding, makes dust-proof effect weaken even and loses efficacy, and there is hole partial metallurgy filter dirt sheet inside, can not filter the sand and dust that diameter is less.
Summary of the invention
The object of the invention is to: for the problem of above-mentioned existence, provide a kind of brake activation valve exhaust performance that neither affects, can stop again sand and dust to enter the dustproof freeing pipe for brake activation valve in the braking valve body.
Technical scheme of the present invention is achieved in that dustproof freeing pipe for a kind of brake activation valve, it is characterized in that: comprise straight tube and protection cylinder, described straight tube one end is communicated with the brake activation valve exhaust outlet, its other end is communicated with protection cylinder, radially be provided with exhausr port along it on described protection cylinder, in described straight tube, end connection corresponding to protection cylinder, be provided with catch, described catch one side and straight tube end are hinged, under state of nature, described catch is separated straight tube and protection cylinder.
Dustproof freeing pipe for brake activation valve of the present invention, the end face that its described straight tube is corresponding with catch is inclined-plane, described catch is fitted with the straight tube inclined surface under Action of Gravity Field.
Dustproof freeing pipe for brake activation valve of the present invention, its described straight tube is connected with the brake activation valve exhaust outlet, is provided with directed nut on the thread segment of described straight tube.
Dustproof freeing pipe for brake activation valve of the present invention, its described catch is hinged by straight pin and straight tube end, and described protection cylinder is connected with straight tube by screw.
The present invention makes the unidirectional air draft of freeing pipe by inclined-plane and catch are set on straight tube, and in preventing from using, brake activation valve passes through exhausr port inspiration dust, and, by directed fastening nuts straight tube, makes the protection cylinder exhausr port downward all the time.Structure of the present invention is ingenious, does not affect the performance of existing brake activation valve, has guaranteed the brake activation valve discharge directions, has stoped sand and dust to enter in the braking valve body from the brake activation valve exhausr port.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Mark in figure: 1 is straight tube, and 2 is protection cylinder, and 3 is exhausr port, and 4 is catch, and 5 is directed nut, and 6 is straight pin, and 7 is screw.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 1, dustproof freeing pipe for a kind of brake activation valve, comprise straight tube 1 and protection cylinder 2, described straight tube 1 one ends are communicated with the brake activation valve exhaust outlet, described straight tube 1 is threaded with the brake activation valve exhaust outlet, be provided with directed nut 5 on the thread segment of described straight tube 1, the other end of described straight tube 1 is communicated with protection cylinder 2, described protection cylinder 2 is connected with straight tube 1 by screw 7, radially be provided with exhausr port 3 along it on described protection cylinder 2, at described straight tube 1, be provided with catch 4 with the end of the corresponding connection of protection cylinder 2, described catch 4 one sides are hinged by straight pin 6 and straight tube 1 end, the end face that described straight tube 1 is corresponding with catch 4 is inclined-plane, described catch 4 is fitted with straight tube 1 inclined surface under Action of Gravity Field, under state of nature, described catch 4 is separated straight tube 1 and protection cylinder 2.
Principle of work of the present invention: in installation process, when the protection cylinder exhausr port is downward, by tightening directed nut locking straight tube, guaranteed the brake activation valve discharge directions.During the brake activation valve air draft, pressurized air arrives straight tube through the brake activation valve exhaust channel, the pressure reduction of pressurized air and atmosphere promotes catch and rotates around straight pin, catch is affixed on top in protection cylinder, pressurized air arrives in protection cylinder, exhausr port through protection cylinder is discharged, and in this process, brake activation valve exhaust channel one lateral pressure is greater than the protection cylinder exhaust port pressure all the time, and sand and dust can't enter brake activation valve inside.When the brake activation valve exhaust finishes, catch, under the effect of self gravitation, rotates whereabouts around straight pin, until fit with the straight tube inclined-plane, catch has cut off brake activation valve exhaust channel and atmosphere, and sand and dust can't enter brake activation valve inside.Structure of the present invention is ingenious, does not affect the performance of existing brake activation valve, has guaranteed the brake activation valve discharge directions, has stoped sand and dust to enter in the braking valve body from the brake activation valve exhausr port.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
