Valve is an important part of oilfield facilities, especially for the gathering and transportation system, the valve is more widely used. At present, the oil field has entered the development period of high water cut, and the corrosion of high water cut to valves has become increasingly serious. The valve often leaks.
Tips for dealing with oil field valve leakage:
1. The sealing method of valve packing is changed to the combination of oil seal, packing seal and other sealing methods, and the oil seal is installed into the step for interference fit.
2. During the whole assembly process, a certain space is reserved in the stuffing box, and a compression spring is added 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 a downward force on the packing.
3. A round asbestos pad is added between the packing gland and the stuffing box, and then the surface of the gland and the stuffing box is closely bonded through the bolts of the packing gland. Through a period of promotion and application, the leakage phenomenon has been eliminated in production, the maintenance cycle has been extended, the labor intensity of employees has been reduced, and the occurrence of crude oil pollution has been avoided.
