STRUCTURE OF TESTER FOR PARTS OF RAILWAY CAR BRAKE SYSTEM USING ELECTRO-PNEUMATIC CONTROL VALVE

PURPOSE: A structure of a tester for parts of a railway car brake system is provided to test brake parts by using an arrangement of the brake parts and a pressure condition thereof. CONSTITUTION: A structure of a tester for parts of a railway car brake system includes an attachment section having an electro-pneumatic control valve(13), a first distributing valve(21), a second distributing valve(23), a first relay valve(27), a second relay valve(29) and a brake reduction valve(11). Main air pipes are provided to transfer air pressure of a main air vessel to a main air input section(R). Braking pipes are provided to feed air in order to operate the first and second distributing valves(21,23). A controller(17) for controlling the electro-pneumatic control valve is provided to open or close solenoid valves.
