Description

Novel sealing ring

Technical Field

The utility model relates to a sealing washer technical field especially relates to a novel sealing washer.

Background

In industrial machinery, the sealing washer is by the fluid on the wide application sealing machinery, can closely laminate with the sealed face that corresponds through self deformation after the pressurized, improve sealed effect, the sealing washer is at operating pressure and certain temperature range, good sealing performance has, the sealing washer resistance to corrosion is strong, difficult ageing, long service life, the wearability is good, along with the progress of science and technology, people have proposed higher requirement to the sealing washer, current sealing washer includes multiple types such as O type sealing washer, O type sealing washer generally sets up on the sealing washer and installs in the mounting hole, because the clearance of sealing washer and mounting hole is less, the sealing washer takes place to cut the circle phenomenon easily in the installation, and then the leakproofness and the life of sealing washer have been reduced.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is that when current O type sealing washer sets up on the sealing ring and installs in the mounting hole, because the clearance of sealing ring and mounting hole is less, the sealing washer takes place easily and cuts the circle phenomenon in the installation, and then has reduced the leakproofness and the life of sealing washer, the utility model provides a novel sealing washer solves above-mentioned problem.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a novel sealing ring, the sealing ring includes along the first circle body and the second circle body of axial setting, first circle body with the coaxial setting of second circle body, first circle body with the second circle body all is the ring form, the downside of first circle body with the upside of second circle body is connected, the cross-section of first circle body is the rectangle, the cross-section of second circle body is circular.

Further: the sealing ring is made of polyurethane or nitrile rubber.

The beneficial effects of the utility model are that, the utility model relates to a novel sealing washer is through setting up the first circle body and the cross-section that the cross-section is the rectangle for the circular shape second circle body, in the installation, first circle body is one step earlier and the mounting hole contacts mutually, has avoided the second circle body to cut the emergence of circle phenomenon, has guaranteed the leakproofness of sealing washer, and the first circle body of rectangle provides the sealed laminating area more with the mounting hole inner wall simultaneously, has better preventing to extrude the effect, has guaranteed the stability and the life of sealing washer.
