Pipeline valves are controlled fluid delivery system components, which is used to change the channel section and flow direction of medium heating valve, with diversion, off, throttling, non-return, diversion or overflow relief functions. For fluid control valves, valves off from the most simple to the most complex automatic control valve used in the system, and its many varieties and specifications, the valve nominal diameter from large to tiny instrument valve diameter up to 10m Industrial pipeline valves. Can be used to control the water, steam, oil, gas, mud, corrosive media, liquid metals and radioactive fluids and other types of fluid flow, the valve working pressure from 0.0013MPa to 1000MPa EHV inlet valve work temperature from -270 ℃ ultra-low temperature to a high temperature of 1430 ℃. 1, the valve should pay attention to the storage environment, should be stored in dry and ventilated room, and blocked both ends of the path. 2, the valve should be checked regularly and remove dirt on it, apply anti-rust oil coating on its surface. 3. Install the valve after application, it should carry out regular maintenance valve to ensure proper operation. 4, you should check the valve sealing surface wear of the exhaust valve, and repair or replacement under the circumstances. 5, check the stem and stem nut trapezoidal thread wear, packing Obsolescence failure, etc., and replace as necessary. 6, to deal with the valve sealing performance tested to ensure their performance.
