Place of Origin:
China
Brand Name:
Tieke
Model Number:
TWG
Brief introduction:
TWG series empty / load equipment is applied for Chinese TB standard air brake system for the purpose of adjusting the brake cylinder pressure according to the different loading condition of the freight wagons.
TWG series empty / load equipment is mainly composed of two parts: T type adjust valve and WG type sensor. T type adjust valve is connected in the pipelines from 120 valve or GK valve to brake cylinder. WG type sensor is mounted on the bogie and its retaining iron is fitted on the cross beam or side frame of the bogie. All the other braking equipment like control valve, auxiliary air cylinder, pressure reducing air chamber and brake cylinder are in the same position as original brake system and no need to be changed.
Main parameters:
| Name | Air Brake Parts Empty / Load Equipment Variable Load Adjustment Device |
| Application | Adjust brake cylinder pressure according to the load of freight wagons |
| Working temperature | -50℃～+70℃ |
| Applicable train pipe rated pressure | 500 KPa, 600 KPa |
| Brake cylinder pressure full loaded | 360±10 kPa |
| Brake cylinder pressure half loaded | 230±40 kPa |
| Brake cylinder pressure empty |
140±15 kPa (when train rated pressure 500 kPa); |
| Matched brake cylinder size | 14’’ or 10’’ |
Main technical features:
(1) With a simple and reliable new weighing mechanism, the sensing valve senses the change of the deflection of the pillow spring during each braking and has a good follow-up to the vehicle vibration. The contact rod retracts in the released state, greatly reducing the wear and improving the service life.
(2) With strong versatility and adaptability, the original double membrane plate structure is adopted, and the empty and load pressure can be set in a large range according to the different needs of the vehicle.
(3) It could be matched with the main brakes like 120 type and GK type, and add the function of stepless automatic adjustment of empty and load remaining the basic performance of the original brake unchanged.
(4) The max. pressures of brake cylinder in empty and loaded conditions could be set in a considerable range according to the different tonnage, speed, the friction performance of high friction synthetic brake shoes. It can adapt to cylinder sizes:φ 356m × 254m, φ 254m ×254m .
(5) No matter in empty or loaded status, the device has obvious and stable initial jump of brake cylinder pressure.
(6) Adopt hi-tech new structure, new material and new technologies in the design of the device. Such as anti loose nut, polymer wear resistant material, multi gases penetration surface treatment, etc.
