Special For Oil Field Globe Valve
Description
Product Usage
Oilfield-specific valves are forced-sealed valves, so when the valve is closed, pressure must be applied to the valve flap to force the sealing surface to not leak. When the medium enters the valve from below the clapper, the resistance to be overcome by the operating force is the friction force of the valve stem and the packing and the thrust generated by the pressure of the medium. The diameter should be large, otherwise the failure to bend the valve stem will occur.
Installation Requirements
1. The inner cavity of the oilfield special valve should be cleaned before installation, and the defects caused during transportation should be removed;
2. Fully add lubricating oil before commissioning the various lubrication parts of the oilfield special valve transmission device;
3. The installation of the oilfield special valve should keep the butterfly valve drive shaft in a horizontal state and the piston valve vertically upward;
4. Before using the oil field special valve, the transmission device should be debugged to keep the various functions of the transmission device intact, and the limit stroke and over-torque protection control are reliable;
5. Before starting the electric device, you should carefully read the manual provided with the electric device.
Product parts materials
1. After using the oil field special valve, the opening and closing operation status should be regularly observed, and the problems should be dealt with in time;
2. Add lubricating oil regularly to maintain good lubrication conditions of all moving parts;
3. After using for a period of time, if you find that the piston of the oil field special valve is not closed tightly, you should check and replace the piston ring.
