In order to solve the above technical problems, the technical solution adopted in the utility model is: a kind of novel seal lower resistance knot
Structure valve rod, including valve-rod body, the valve-rod body are divided into linkage section, light bar segment and thread segment from top to bottom, and the linkage section is used for
Connect with torque handle, be provided with the oil fuel tube of perforation among linkage section and light bar segment, the oil fuel tube lateral openings with it is fuel-displaced
Hole, the oil outlet are located on the side wall of light bar segment；The light bar segment upper/lower terminal is respectively arranged with the first sealing ring and second
Sealing ring, the oil outlet are set between the first sealing ring and the second sealing ring；
First sealing ring and the second sealing ring are two annulars arranged in a crossed manner, corresponding position in the light bar segment
It is provided with the first sealing ring fixing groove and the second sealing ring fixing groove, first sealing ring and the second sealing ring pass through respectively
One sealing ring fixing groove and the second sealing ring fixing groove are fixed in light bar segment.
Further, frosted section is provided in the light bar segment, the side wall of the frosted section is frosted structure, the frosted
Section is arranged between the first sealing ring and the second sealing ring.
Further, the oil outlet totally four, are arranged along shaft length direction, and two neighboring oil outlet is opened on respectively
The opposite direction of light bar segment.
Further, equadag coating is provided on the outside of the frosted section.
The utility model provides a kind of novel seal lower resistance structure valve rod, after valve rod comes into operation, by oiling
Pipe oiling, provides lubrication between valve body and valve rod, it is possible to reduce friction, while air or liquid between being discharged, into
One step prevents from corroding；The oil injected in order to prevent flows out between valve rod and valve body squeeze, and pollutes fluid in valve body or valve, this reality
A kind of sealing ring is further devised with novel, which is different from the sealing ring of traditional monocycle, intersects annular setting for two.
In valve rod rotation, such sealing ring setting can make spatial variations between valve body and valve rod, be uniformly distributed lubricating oil.
The oil outlet being arranged oppositely can guarantee that in valve rod unbalance stress, side oil outlet resorption parts of lubricating oil is prevented
Only lubricating oil is excessive.Equadag coating on the outside of frosted section can be acted on auxiliary lube oil.
The utility model can provide sealing simultaneously, prevent lubricating oil from leaking, have good practical function.
Detailed description of the invention
