Model 61 Vacuum isolating stop valve
Chief features and usages:1/The main body of the series valve uses a casting and forging structure and has a double direction seal of parallel secondary semi-forced,double sealing and the motions of both the sealing face to its due position duue position due podition and the tapered block to wedge up are seprated to have zero leadage come ture.2/The sealing face is of a small frictional force if motion.Lightly opened and closed and has a self copensation function for wearing.3/Simple and compact sturcture easy to more than 10 years of long duration.4/A vacuum sealing structure is set in the sealing with the expansice material of high strength to completely isolate the system from air.5/Two connecting ways of flange and welding, two ways to drive of hand and electric operation. the valve can be used as the open and close device for the pipelines under the working temperature≤425°C,the working medium of water,steam or air ,especialy suitable to act as the vacuum isolating sealing for the system of eteam turbine's condesation and vacuum negative pressure in steam power plants. |
