Problems solved by technology
[0004] The object of the present invention is to provide a valve stem nut lubricating device with good lubricating effect for petroleum pump valves, which has the advantages of storing lubricating oil, uniform coating of lubricating oil on the surface of the valve stem and recycling lubricating oil, and solves the problems of existing pump valves. It has the function of storing lubricating oil, and lubricating oil can only be added once at a time, and the lubricating oil can only be partially added to the surface of the valve stem, and the user needs to turn the valve stem back and forth to make the surface of the valve stem completely coated with varnish. Lubricating oil is time-consuming and labor-intensive, causing inconvenience to users

The invention discloses a valve stem nut lubricating device with a good lubricating effect for a petroleum pump valve. The valve stem nut lubricating device comprises a valve body; a valve cover is fixedly installed at the top of the valve body through first bolts; a nut base is fixedly connected to the top of the valve cover; and a valve stem body is arranged in an inner cavity of the nut base. According to the valve stem nut lubricating device, lubricating oil is injected into an oil collecting annular groove through an oil injection mechanism, the oil collecting annular groove can store thelubricating oil, and when the lubricating oil needs to be added to the surface of the valve stem body, a downward pressing mechanism is adjusted through an adjusting mechanism to move downwards to compress the lubricating oil in an inner cavity of the oil collecting annular groove; and the lubricating oil in the inner cavity of the oil collecting annular groove is evenly sprayed to the surface ofthe valve stem body through a plurality of oil leaking holes, the purposes of storing the lubricating oil and evenly coating the lubricating oil on the surface of the valve stem can be achieved, redundant lubricating oil can fall into the inner cavity of a hopper body to be recycled and is discharged through an oil discharging mechanism, and the purpose of recycling the lubricating oil can be achieved.
Description
technical field [0001] The invention relates to the technical field of petroleum pump valves, in particular to a valve stem nut lubricating device with good lubricating effect for petroleum pump valves. Background technique [0002] Pump valve is a general term for pumps and valves. It is an industrial equipment used for liquid transportation. It is not used for pump valves or valves with pump functions. The reason why pumps and valves are often associated is the use occasion, that is, there are pumps Some places generally have valves, and some places often need pumps. They are all used for liquid transportation. Of course, valves are also used for gases, and vacuum pumps are also related to gases. [0003] Long-term use of petroleum pump valves requires regular addition of lubricating oil to reduce wear and prevent rust and reduce the service life of petroleum pump valves. The existing pump valves do not have the function of storing lubricating oil, and lubricating oil can ...
