Working principle and structure of the distribution of pneumatic valve

distribution of pneumatic valve control action according to the train pipe pressure change air and exhaust air cylinder, and through the change to the pneumatic valve, pneumatic valve action to achieve locomotive brake, the holding or ease. The importance of distribution of pneumatic valve in air brake, like the heart of the people, if in the event of failure, the entire vehicle air brake will complete failure, safety, there is no guarantee. http://www。 zgbfw。 com/info/

distribution of pneumatic valve structure type air distribution of pneumatic valve by the main pneumatic valve, pneumatic valve of emergency and intermediates of three parts, the main pneumatic valve and emergency valve are connected by bolt and intermediates. Intermediate bolts installed in the car frame.

intermediates intermediates with cast iron, cast shape is rectangular in shape, external four facades respectively as the main pneumatic valve, pneumatic valve seat and the emergency brake pipe, deputy wind wind earthen pipe, earthen pipe, brake earthen pipe header, three separate cavity through the channels of internal related to main pneumatic seat or emergency pneumatic seat hole connected. Intermediates on emergency pneumatic valve installed in the body of the lateral, and pneumatic valve installation of emergency bridge adjacent right side is given priority to pneumatic valve installation, and emergency pneumatic valve bridge above the left side of the adjacent pipe installation work for air cylinder connecting pipe, below for brake pipe connecting pipe, another side tube above the bridge as the wind cylinder connecting pipe, below for cylinder connecting pipe. Intermediates in the three cavity, rely on emergency pneumatic valve side of the Angle for installation. L in emergency room, the Angle is. L bureau reduction chamber, another large volume of intermediates ( 。 L volume of the chamber. Intermediate main pneumatic valve installed on the surface of the seat train tube pathway on L has superior filter performance, mechanical performance of cup dust filter. http://www。 zgbfw。 com/info/

the main distribution of pneumatic valve is the heart of the pneumatic valve parts, it changes according to the different pressure of brake pipe, control brake inflatable, ease, brake, pressure, and so on. The pneumatic valve by the function department, plastic department, balanced department, bureau department as well as reduce booster pneumatic valve, pneumatic valve of five parts. http://www。 zgbfw。 com/info/

emergency emergency pneumatic valve pneumatic valve is designed to improve the emergency braking performance and independent setting. Action, action is not acceptor pneumatic valve department of traction and influence. Is the work of emergency pneumatic valve during emergency braking pressure, have strong local relief emergency brake pipe, to speed up the exhaust brake pipe, improve the sensitivity and reliability of train brake emergency braking, improve emergency braking wave velocity, improve emergency braking performance. Emergency pneumatic valve by pneumatic valve cover of emergency, emergency piston, sealing ring, emergency, emergency piston diaphragm, emergency piston clamp, clamp nut, stable spring, fresh air, pneumatic seat, emergency pneumatic valve and exhaust cover cushion, air cushion rivet, strainer mesh, circulating pneumatic valve ( Rubber sandwich pneumatic valve, pneumatic valve spring, snort snort pneumatic valve guide bar, fresh air, pneumatic valve, pneumatic valve of emergency under cover, etc. http://www。 zgbfw。 com/info/
