Background
In the production process of the petroleum industry, the flow is controlled and switched by a valve frequently, and due to the fact that a valve lead screw is exposed in the air for a long time, rainwater, oil stains and other dirt are corroded, the abnormal phenomenon of valve use is easy to occur, accident potential is formed, the maintenance workload is increased, and the production cost is increased. If the valve which is out of service for a long time is corroded for a long time, the valve cannot be normally opened or closed, normal production is affected, potential safety hazards exist, and a valve screw rod must be protected. Because the lead screw is easy to rust, and needs to be cleaned and maintained with oil in time, if daily manual cleaning and maintenance are adopted, the labor intensity is high, the time is long, the cost is high, the influence of weather and environment is large, the environmental pollution is large, and the cleaning production, the energy conservation and the consumption reduction are not facilitated. A valve lead screw cleaning and protecting device is disclosed in the patent number: 201220484787.X, its fixed steel bushing is fitted with the cleaner, cleaner and fixed steel bushing are cylindrical with one end sealed, the cleaner is connected with steel wire card bed and sponge card bed of the oil, the fixed steel bushing is fixed on hand wheel of the valve through the internal thread, the apparatus not only dust-proof, rain-proof and greasy dirt proof, can better protect the lead screw, reduce the unnecessary corrosion, and can get effects of derusting, cleaning, oiling and maintaining while opening and closing the valve; the steel wire and the oil-containing sponge are fixed by the clamping grooves, so that the replacement is convenient, the cost is low, and the cost is further saved. This patent has only solved the lead screw maintenance problem on valve upper portion, but has not solved the maintenance problem of valve support mid portion lead screw.
