四川泸州长江液压件厂近年来研制成功的全液压汽车起重机用多路换向阀——2005型多路阀和DL-8型多路阀,较好地满足了我国引进日本多田野公司等大中吨位汽车起重机液压阀国产化的需要。 2005型多路阀系汽车起重机的上车阀,采用了负载反馈新技术,系统压力与负载保持一致,有效地减少了系统发热,节约了能耗。该阀还同时采用了不同通径阀体相组合和合流阀体等先进技术,体积比同类型阀减小30～40％。其主要技术参数为:
In recent years, Sichuan Luzhou Yangtze River Hydraulic Factory developed a fully hydraulic truck crane with multi-way valve - 2005-type multi-way valve and DL-8-type multi-way valve to better meet the introduction of Japan’s Tade field and other large companies In tonnage truck crane hydraulic valve localization needs. 2005 multi-way valve truck crane on the car valve, using load feedback technology, the system pressure and load to maintain the same, effectively reducing the system heat, saving energy consumption. The valve also uses a combination of different path valve bodies and merging valve body and other advanced technology, the volume of the same type of valve to reduce 30 to 40%. The main technical parameters are:
