针对客车水栓与机车水鹤给水阀门存在维修工作量大,使用寿命短,操作比较笨重等问题。郑州分局供电给水分处、郑州水电段、郑州蝶阀厂等单位,于1991年5月,自筹资金,采用新技术、新工艺、新材料,成功地研制出客车水栓、机车水鹤两种新型铁路给水蝶阀。它具有以下主要技术特点:(1)体积小、重量轻。长度为闸阀、截止阀的1/5-1/9,重量为闸阀、截止阀的1/6-1/7。(2)使用寿命长,全启闭次数达一万次以
For the bus faucet and locomotive water crane water valve there is a heavy maintenance workload, short service life, more bulky operation and other issues. Zhengzhou Branch power supply to the water office, Zhengzhou Hydropower Section, Zhengzhou Butterfly Valve Factory and other units, in May 1991, self-financing, the use of new technologies, new technology, new materials, successfully developed bus hydrants, two locomotives crane New railway water butterfly valve. It has the following main technical features: (1) small size, light weight. The length of the gate valve, globe valve 1 / 5-1 / 9, the weight of the gate valve, globe valve 1 / 6-1 / 7. (2) Long service life, full opening and closing times up to 10,000 times
