Sealing lubrication of flat valve for water well drilling rig accessories

The flat plate valve thrust bearing of manual water well drilling rig accessories adopts lithium grease. The consumption of grease should be checked after each maintenance. If deterioration, pollution or lack is found, it should be replaced or supplemented immediately. In the process of maintenance, if slight leakage occurs at the valve stem sealing packing sealing place, sealing grease can be injected through the sealing grease injection valve on the valve cover to prevent leakage, but after the completion of construction, the sealing should be replaced in time. Before filling the valve sealing grease, must consider the internal pressure of the valve body, the pressure of the high-pressure injection gun used must be greater than the internal pressure of the valve, in order to successfully inject the sealing grease. Fill the injection gun with 7903 sealing grease and connect it to the injection valve on the valve cover through the hose. Operate injection gun and inject seal grease.
