Problems solved by technology

[0003] When lubricating oil is added to the existing valve stem nut, the lubricating oil is generally sprayed directly to the outside of the nut. This way of adding lubricating oil, because the nut is in a tightened state when fixing the screw rod, it is impossible to lubricate. The oil is added to the inside of the nut, and there is no good lubrication effect between the nut and the valve stem, which will cause rust inside the valve stem

Abstract

The invention relates to the field of valve rod nut lubrication, in particular to a valve rod nut lubricating device for a petroleum pump valve. The device comprises an oil storage bottle and further comprises a driving spraying box fixed to the top face of the oil storage bottle, wherein the bottom face of the driving spraying box communicates with the oil storage bottle; a filtering assembly, wherein the filtering assembly is located in the middle of the oil storage bottle and is in sealed sliding connection with the middle of the oil storage bottle; a micro oil pump located on the lower side of the middle of the driving spraying box, wherein one end of the micro oil pump is connected with the bottom of the oil storage bottle, and the other end of the micro oil pump is connected to the outer side of a spiral nozzle; a pressurizing motor located on the top face of the micro oil pump, wherein one end of the pressurizing motor communicates with the outer side of the top face of the driving spraying box, and a one-way valve is arranged at the joint of the driving spraying box and the pressurizing motor; and a sealing nozzle spirally arranged on the outer side of the spiral nozzle in a sleeving mode, wherein and the spiral nozzle is formed in the bottom of the outer wall of one side of the driving spraying box.

Description

technical field [0001] The invention relates to the field of valve stem nut lubrication, in particular to a valve stem nut lubrication device for petroleum pump valves. Background technique [0002] The stem nut is composed of a nut cap and a nut rod; the nut cap is provided with a dust-proof sealing groove, the inner surface of the nut rod is provided with upper and lower ring grooves in turn, and the outer peripheral surface of the nut rod is provided with ring grooves, and the valve stem nut has a certain Strength and pressure resistance, because the stem nut directly gives the stem nut the strength of the stem shaft during the operation of the valve, the stem nut and the stem rotate with the thread, and the friction coefficient of the stem nut is small, so that It can avoid the phenomenon of seizure or rust. [0003] When lubricating oil is added to the existing valve stem nut, the lubricating oil is generally sprayed directly to the outside of the nut. This way of addi...
