Derailment Detector Device Derailed Auto Emergency Brake Valve Railcar

Derailment Detector Device Derailed Auto Emergency Brake Valve Railcar

Brief introduction:

Auto brake derailment detector device is designed, manufactured and tested according to Chinese standard TB/T3224-2010 ‘Automatic brake valve for derailment of railway freight car’.

It adopts mechanical acting mode and could timely connect the main air brake pipes to the atmosphere immediately when it detects the railcar derails, thus applying emergency brake of the train, minimizing the loss caused by derailment accident.

 
Main technical parameters:

Main Structure

Derailment detector device is mainly composed of derailment auto brake valve, branch pipe lines, tees, ball valve,, etc. The core part is derailment auto brake valve, which comprises of valve body, brake valve rod, pull ring, top beam, adjusting rod, acting rod, lock nut, shrapnel, etc.

Working principle:

When the railway freight car derails for some reason, the wheel and axle position will change and the pull ring or top beam of the derailment auto broken valve will touch and collide with axle, and this force is transmitted to the brake valve rod through the adjusting rod and acting rod. The brake valve rod is designed thin wall structure and easy to be broken at out force. Once the brake valve rod is broken, the brake system’s channel to the atmosphere is opened and the emergency brake will be applied immediately.

When the freight wagon is empty and details, the axle of the derailed wheel set breaks the brake valve rod; when the freight wagon is loaded and derails, the axle of the derailed bogie without derailed wheel set breaks the brake valve rod.

The derailment auto braking process could be concluded as below:

Vehicle derailed-detailed axle and wheels position changed-brake valve rod was sheared-brake system pipe opened with atmosphere-train emergency brake

Installation on railcars:

The installation of derailment detector device is to add two branches to the main air pipe of the original air braking system of the railcar, which does not affect the performance of the original air braking system.

The installation of general railway freight wagons, the position sizes of valve, pull ring, top beam and axles (empty load)ΔX,ΔY1,ΔY2 shall comply with below table. For special vehicles, the position sizes shall be calculated according to vehicle parameters.

Installation on railway wagons:
