Description

Technical Field

[0001] The utility model relates to the technical field of railway freight car braking, in particular to a valve clamping device and a test system. Background Art

[0002] The vehicle braking rate is one of the main indicators of the braking capacity of railway vehicles. When a railway vehicle brakes, the braking force needs to match the actual load status of the vehicle. When the vehicle is loaded, sufficient braking force is needed to ensure the braking distance. When the vehicle is empty, a smaller braking force is needed to prevent the vehicle from braking and rubbing the wheels. Therefore, an empty and loaded vehicle adjustment device is installed on the vehicle.

[0003] The assembly and testing of the empty and loaded vehicle adjustment device are generally completed manually, especially the test stage cannot be automated. The existing empty and loaded vehicle adjustment device includes a pressure limiting valve and a sensing valve. During the test, the two valve bodies use two different fixtures. Operators need to frequently manually move and switch fixtures, which is inefficient, time-consuming and labor-intensive, resulting in extended production time and low production efficiency.
