Valve leakage is how is it? How to solve the problem of leakage valves? Valve is an important part of the oil facilities, especially for gathering and transportation system, the more extensive application of the valve. At present, the development of high water cut oilfield, high water content of the corrosion of the valve has become increasingly severe. This phenomenon often leak valve.
Germany indicated rod valve
Valve leakage is how how to solve the problem of leakage of the valve tips?:
1, the way to seal the valve packing, packing and other sealing method combined oil seal into the step interference fit.
2, the entire assembly process, the stuffing aside some space between the seal portion and the remaining filler is added under a compression spring, compression spring on the seal has an upward force on the packing with a downward force.
3, between the packing gland and stuffing added a circular pad of asbestos, and finally through the packing gland bolts so that the surface of the gland and stuffing tight fit. Through the promotion of a period of application in production to eliminate the leakage, extended maintenance intervals, reducing the labor intensity of workers, to avoid oil contamination. |
