为了充分发挥现有GK型制动机的作用,以适应运输的需要。GK型制动机必须在性能上适当加以改进。为此笔者做了以比例阀取代原空车安全阀,GK型三通阀加装局减阀、常用排气阀以及改变GK型三通问滑阀的紧急制动孔、缓解孔尺寸的试验研究。研究结果表明,这些改进,技术上是完全可行的。
In order to give full play to the role of the existing GK brake to adapt to transport needs. GK brake must be properly improved in performance. To do this I made a replacement valve with an empty car safety valve, GK-type three-way valve to reduce the valve installation, the common exhaust valve and the GK three-way valve to change the emergency brake hole to ease the hole size test the study. The results show that these improvements are technically feasible.
