Valve is an important part of the oilfield facilities, especially for gathering and conveying system, the valve is more widely used. At present, the oilfield enters the period of high water cut development, and the corrosion caused by high water content on the valve is also increasingly serious. Valve often see the phenomenon of leakage. Tips to deal with oil field valve leakage problems: 1, the valve packing sealing method to seal, packing seal and other sealing methods combined, the oil seal into the step for the interference fit. 2, Throughout the assembly process, leave some space in the stuffing box, add a compression spring between the lower part of the oil seal and the remaining packing, so that the compression spring has an upward force on the oil seal, and there is a downward force on the packing force. 3. Add a circular asbestos cushion between the packing gland and stuffing box. Finally, the gland and packing box's surface are closely fitted by the bolts of packing gland. Through a period of popularization and application, in the production to eliminate the leakage phenomenon, extending the maintenance cycle, reducing the labor intensity of workers, to avoid the occurrence of crude oil pollution.
