Embodiment Construction
[0013] Below in conjunction with accompanying drawing, the present invention is described in detail.
[0014] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0015] Such as figure 1 As shown, a variable flux exhaust plug includes an exhaust plug body 1 and a variable flux plunger 2. A deep groove 3 and a shallow groove 4 are arranged on one end face of the exhaust plug body 1. The variable flux column One end of the plug 2 passes through the exhaust plug body 1 and a round pin 5 corresponding to the deep groove 3 and the shallow groove 4 is provided at the end thereof, and the variable flux plunger 2 is connected with the operating handle 12 through t...

The invention discloses a variable-flux venting plug which comprises a venting plug body and a variable-flux plunger. The end face of one end of the venting plug body is provided with a deep groove and a shallow groove, one end of the variable-flux plunger is provided with round pins correspondingly matched with the deep groove and the shallow groove, the periphery of the other end of the variable-flux plunger is sleeved with an O-shaped seal ring, and an annular exhaust space is formed between the variable-flux plunger and the venting plug body. A returning spring sleeves the variable-flux plunger in the annular exhaust space. The variable-flux plunger is provided with a central exhaust through hole which is through in a front-rear mode, the variable-flux plunger is provided with a radial exhaust through hole communicated with the annular exhaust space, and the venting plug body is provided with a vent hole communicated with the annular exhaust space. An exhaust access is changed by controlling the position of the variable-flux plunger, the variation of exhaust flux is achieved, and a brake cylinder in a railway vehicle brake system is controlled to relieve the flux of an exhaust port, so as to achieve the goal of meeting the remission time needed for the vehicle brake cylinder.
Description
technical field [0001] The invention belongs to the technical field of exhaust plugs, in particular to a variable flux exhaust plug used in the braking system of railway vehicles. Background technique [0002] In the current domestic railway vehicle braking system, the relief time required by the vehicle brake cylinder is uniform, and there is no component that can control the brake cylinder to relieve the flux of the exhaust port. Now, the brake system will exit and need to operate in the two-stage adjustable range for the release time of the brake cylinders. Contents of the invention [0003] The object of the present invention is to: aim at the above-mentioned existing problems, provide a kind of variable flux discharge that can control brake cylinder to relieve the exhaust port flux in the railway vehicle braking system, so as to achieve the purpose of relief time required by the vehicle brake cylinder air lock. [0004] The technical solution of the present inventio...
