介绍了安装在提速机车上专门用于列车双管供风的jty—1型空气减压阀的结构和原理，并介绍了使用、检修及常见故障的处理方法。
The structure and principle of jty-1 type air reduction pressure valve for double wind pipe of installation in the raising speed locomotive are described.
如输入气压已达要求，应检查空气过滤减压阀的调节是否正确，表压显示能否满足切割要求。
If the input pressure has reached requirements, should check air filter relief-pressure valve regulation is correct, table press show you could meet the cutting requirements.
否则应对空气过滤减压阀进行日常维护保养，确保输入空气干燥、无油污。
Otherwise deal with air filter relief-pressure valve for routine maintenance, ensure that the air dry, no pollution.
