How to Clean and Lubricate a Trap?

These places, such as the surface of a valve, the stem, the trapezoidal thread, the nut, the gear, worm and worm whee and so on, are easy to accumulate dusts, greasy dirt and medium residues, which will wear and corrode valves greatly.

So, it is important to keep the valve outside and moving parts clean, and to keep the intact of valve paint. It is suitable to use a brush and compressed air to clear dust in valves; it is suitable to use a rag to scrub the acme threads and the edges; as for the greasy dirt residues in a valve, they can be cleaned by steam sweeping, or use cooper wire to scrub so that the finished surfaces and mating surfaces can show a metallic luster and the paint surfaces show its original color. Traps should be checked regularly by special personnel in charge. Open the flushing valve and the plug below the trap regularly to clean them, or disassemble them regularly to rinse to avoid blocking of valves by dirt.

Lubricant has various categories, such as engine oil, butter, molybdenum disulfide, graphite,etc.Engine oil and butter are not suitable for high-temperature valves since these lubricants melt and run away in high temperature, while molybdenum disulfide and graphite powder are more suitable for these valves.Uncovered parts lubricated with butter or other oils are liable to be contaminated with dust, for example, the trapezoidal thread,the gear and so forth. If molybdenum disulfide and graphite powerder are adopted for lubrication, these parts will not be contaminated with an lubricating effect better than that of butter.

It’s not easy to daub the graphite powder directly, but you can use it by adding some engine oil or water. Plug valves sealed by oil must be injected with oil according to time, or it is easy to abrade or leak.
