Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] see Figure 1-6 , an angled plug door for train braking, comprising a plug body 1, one side of the plug body 1 is integrally formed with a vertically mounted body 2 arranged in the up and down direction, the inner cavity of the plug body 1 and the cooperation of the vertically mounted body 2 converge. The fixed sleeve is provided with a sealing seat 3, and the middle part of the sealing seat 3 is provided with a through hole in the axial direction and v...

Abstract

The invention relates to the technical field of braking equipment and discloses an angle cock for train braking. The angle cock for train braking comprises a cock body, wherein one side of the cock body is integrally molded with a vertically arranged body, and an inner cavity of the cock body and the vertically arranged body are matched and intersected to form a fixed sleeve which is provided with a sealing seat. According to the angle cock for train braking, airflow generated in the train running process of a fan drives a rotating shaft to rotate to drive a magnet disc to rotate, a first thread cuts a magnetic field of the magnet disc to generate eddy current to generate heat, heat is conducted to the top of a plug plate, an air bag is heated and expanded to drive the plug plate to move downwards, and an axial through hole of a sealing seat can be opened; when the cock is forgotten to be opened before a train is started, the cock can be automatically opened, a heat conduction rod moves downwards to drive a protruding block to be matched with a braking groove, a first thread is meshed with a second thread, an air bag is cooled and contracted, the heat conduction rod is limited by the braking groove, and under the elastic force effect of a first spring, a plug plate cannot rise and is automatically closed; it is guaranteed that the cock can be kept open in the train running process.

Description

technical field [0001] The invention relates to the technical field of braking equipment, in particular to an angled cock for train braking. Background technique [0002] As the speed of the train continues to break through, its braking effect is becoming more and more important. The existing train has an air brake mechanism, and the compressed air is driven from the engine at the front of the train to the main pipe. A corner plug will be installed at the end of each train. , Before driving, it is necessary to open all except the last corner plug door, so that the air brake cylinder installed at the wheel place under each compartment has air injection for braking. [0003] There is a handle on the existing corner plug door, which is riveted on the corner plug door through a pin, and the mandrel can be driven to rotate by rotating the handle. The bottom of the mandrel is fixed with a ball core, and the ball core is installed on the plug. In the axial through cavity of the se...
