摘　　要：货车新型阀样机已完成试制工作,该阀构造简单,作用性能稳定、可靠,经模拟试验其主要性能指标可达到紧急制动波速260m/s,常用制动波速180m/s以上,缓解波速150m/s;它适应压力保持操纵,可与GK阀混编,能适应开行万吨列车需要。The development of prototype of new type freightcar brake valve has been completed; such valve hassimple construction, stable and reliable operation per-formance, and after analog test. its main performanceparameter can attain to 260m/s of emergency brakingwave propagation speed, more than 180m/s of serviceapplication wave propagation speed and 150m/s of rel-ease wave propagation speed. It is suited for pressureholding operation and can be used in trains mixedlyequipped with K triple valves, so it can meet thedemand of 10,000 ton train operation.
