济南市市中给水设备机械厂生产的《油压微阻缓闭止回阀》在“国家七五星火计划成果博览会”上荣获银奖,在“92北京国际发明展览会”上荣获发明银奖。用户洛阳市自来水公司来函对该产品的反映如下: 1.消除水锤是微阻缓闭止回阀的主要功能。采用水压缓闭止回阀,经过一段时间使用后,活塞不动作或动作不灵敏,现场维修也比较田难。济南厂产品是油压缓闭止回阀比较合理,经过三
The “Hydraulic Pressure Micro-Resistivity Slow Close Check Valve” produced by Jinzhong Shizhong Water Supply Equipment Machinery Plant won the Silver Award at the “National Seven-Star Spark Program Achievements Expo” and won the invention silver award at the “92 Beijing International Invention Exhibition”. . Users Luoyang City Water Company’s letter to reflect the product is as follows: 1. Elimination of water hammer is the main function of micro-resistance slow closing check valve. The use of water pressure slow closing check valve, after a period of use, the piston does not move or action is not sensitive, on-site maintenance is also more difficult. Jinan plant product is a relatively slow oil pressure check valve, after three
