长江液压件厂研制成功一种片式结构的DL-8型多路换向阀,通过各种试验以及用户使用证明,完全能替代日本多田野汽车起重机下车阀。 DL-8型多路换向阀主要用于控制汽车起重机支腿的伸缩,还可以用其于他各种工程机械的液压系统中。在设计中,除保持原有性能外,还着重考虑了加大通往上车阀的油路通道,使中位压力损失大为下降,减小了系统的发热。该阀为手动操纵,第一连择阀可根据用户需要选用钢球定位或弹簧复位的方式,其余四连换向阀均系采用钢球定位方式,具有操纵
The Yangtze River Hydraulic Factory successfully developed a chip structure of DL-8-type multi-way valve, through a variety of tests and user certification proved to be able to completely replace the Japanese TADANO truck crane off valve. DL-8 multi-way directional control valve is mainly used to control the telescopic crane legs, you can also use it in his hydraulic system of construction machinery. In the design, in addition to maintaining the original performance, but also emphatically considered to increase access to the valve on the road, so that the median pressure loss greatly reduced, reducing the system’s heat. The valve is manually manipulated, the first selector valve can be selected according to user needs ball positioning or spring reset approach, and the remaining four-way directional valve are used ball positioning, with manipulation
