Abstract

The embodiment of the invention provides a jump pressure limiting mechanism and an air braking system, and relates to the field of air braking systems. The problem that a pressure limiting structure needs to adopt a combination of two valves, and the size is large is solved. The jump pressure limiting mechanism comprises a valve body, a jump valve, an inflation valve and a pressure limiting piece; the valve body is provided with an air inlet, a first cavity, a second cavity and an air outlet; the jump valve is arranged in the first chamber; and the inflation valve is arranged in the second cavity, the jump valve and the inflation valve are both connected with the pressure limiting piece, and the pressure limiting piece is used for driving the jump valve and the inflation valve to move in the pressure change process in the pressure limiting cavity. The air braking system comprises a jump pressure limiting mechanism. When the first chamber and the second chamber are opened at the same time, the air outlet can quickly output pressure air; when the first chamber is closed and the second chamber is opened, the output speed of the air outlet can be controlled; and the first cavity and the second cavity are closed at the same time, the current pressure state of the air outlet can be kept, and therefore switching of the three pressure limiting states is achieved.

Description

technical field [0001] The invention relates to the field of air brake systems, in particular to a jump pressure limiting mechanism and an air brake system. Background technique [0002] The speed, size and maximum value of the braking force output of the rail vehicle braking system are closely related to the braking demand of the train, and also affect the running quality of the train. [0003] The jump pressure limiting mechanism in the current railway vehicle braking device uses two valve combinations to realize pressure limiting, and has a complex structure and a large size. Contents of the invention [0004] The purpose of the present invention includes, for example, to provide a jump pressure limiting mechanism, which can improve the problem that the pressure limiting structure needs to use two valve combinations and has a large size. [0005] The purpose of the present invention is also to provide an air braking system, which can improve the problem that the pressu...
