Research On The Rapid-Speed Wangon Air Control Valve

According to 《Railway Important Technology Policy》 and railway technology develop layout related, the highest run speed of railway wangon will heighten to 160km/h。 This is important task of our domestic wangon braking technology developing now。 Therefor, railway ministry eatablish item "research on the 160km/h rapid speed wangon braking system " (item serial number: 2004J027) 。 Item demands: confirm system scheme based on the braking systems now by analysis and account, consulting foreign experience and criterion。 Stress on taking into account the form and performance of control valve, the wheel defended slip, the form of brake tile and the problem of heat load, moreover, consult the problem of geting along with currency wangon, The paper stress on research of the control valve to suit to rapid speed wangon—the core of the 160km/h rapid speed wangon braking system。Firstly, the paper analyze actuality of 160km/h rapid-speed wangon braking system both at home and abroad, consulting foreign technology maturated about the rapid-speed wangon braking system, it is proposed that the scheme thinking of 160km/h rapid-speed wangon braking system to suit to our domestic railway。Subsequently, particularly analyze and discuss the control valve—the core of 160km/h rapid speed wangon braking system。 Above all, recommend performance characteristic of 120 type wangon control valve and 104 type carriage distribute valve mostly used at home now, put up application analysis to 120 type wangon control valve and 104 type carriage distribute valve, account for both 120 type wangon control valve and 104 type carriage distribute valve cannot meet requirement of 160km/h rapid speed wangon braking, bring forword to the basic function of the control valve taked on to suit to our domestic 160km/h rapid speed wangon 。 Then, aim at our track braking technical characteristic now, put up the design of technology scheme of the control valve to suit to rapid speed wangon, analyze the action theory of the technology scheme., Subsequently, based on technology scheme assured, consult 120 type wangon control valve and 104 type carriage distribute valve and foreign design idea maturated about the control valve, joining our domestic railway technicsactuality now, accomplish working drawing design of the control valve to suit to rapid speed wangonD Then, go along sample trial-manufacture according to the working drawing, aim at the question appeared in test, go along optimizing design to the structure of the control valve portion parts oFinally, compile the test criterion of the control valve to suit to rapid speed wangon, put up performance test to the sample, moreover, put up analyze to test result o...
