Abstract

The utility model discloses a long-term sealing and energy-saving piston ring, relating to the technical field of a piston ring. The design of the long-term sealing and energy-saving piston ring mainly solves the technical problems that the existing piston ring has daily serious air leakage and shorter service life when the existing piston ring is used. The long-term sealing and energy-saving piston ring is characterized in that an arc pin block (2) is made on the outer lower edge on one end of a ring body, and an arc pin opening (3) is made on the other end of the ring body. The arc pin block (2) and the arc pin opening (3) are mutually matched in work, which makes an end gap always blocked by the arc pin block (2), and thereby, the long-term sealing performance and the long used life performance of the ring body in a cylinder are realized.

Description

Long-term sealing and energy-saving piston ring

Long term seal energy-saving piston ring relates to the piston ring technical field.

At present, the piston ring that domestic and foreign current is used has a shortcoming to be to use the time to increase, and gas leakage is on the rise, and working life is also shorter.This long term seal energy-saving piston ring designs for solving this contradiction.

This novel piston ring, roughly the same with existing piston ring, two end constructions of different is ring body have special adaptations.Concrete technology is shown in Figure of description.(1) is the piston ring body among the figure.(2) be to link to each other, and be in external lower margin that length is the arc bolt piece of 10-15 millimeter (also being the part of ring body) with ring body one end.(3) the arc bolt mouth that can mutually coincide with bolt piece (2) for making at ring body the other end external lower margin.(4) be the vertical ringwall that links to each other at the ring body inward flange and with ring body, its effect is to stop high-pressure gas to release from the annular groove bottom.(5) be the ring eaves of arc bolt mouth top, its effect is to stop high-pressure gas to release from top to bottom.(6) be the ring body splaying.

Stop high-pressure gas from ring body splaying (6), to release, mainly ring body splaying (6) are blocked and realize by arc bolt piece (2).For this reason, shape, the size of arc bolt piece (2) and arc bolt mouth (3) all must be manufactured identically, to guarantee that they have good stretchability and coincide under the effect of external force and ring body elastic force, make arc bolt piece (2), can block ring body splaying (6) all the time.Because the length of arc bolt piece (2) is much larger than the limiting value (being generally about 2mm) of ring body splaying, so, although the ring body periphery is frayed in cylinder, ring body splaying (6) is constantly increased, arc bolt piece (2) is when protruding, also will not lose resistance envelope effect, thereby realize the long term seal effect of piston ring cylinder to ring body splaying (6).

The tolerance limit of existing piston ring end gap is about about 2mm, and this novel piston ring, because the long-term resistance envelope effect of arc bolt fast (2) to the ring body splaying arranged, so, even its splaying value reaches 5 to 6mm, the phenomenon that also can not leak air is so prolong greatly than existing piston ring working life.

Use this novel piston ring, following advantage and good effect are arranged: can make the compression ratio and the power output of motor, remain on the ideal designs state for a long time; Long service life can reduce the number of times and the trouble that more renew ring; Save fuel oil and lubricant oil greatly; It is more approaching complete to burn, and reduces environmental pollution; Can reduce the sheet number of cylinder inner seal ring; Reduce the human and material resources and the financial resources of social production piston ring, the significant social economic benefit is arranged.

This novel piston ring is produced material, technology, flow process is identical with existing piston ring, simple in structure, cost is not high, and manufacturing mechanism does not have special, former single-cast piston ring producer, and under original manufacturing mechanism condition, the operation of just being satisfied with.

Claims

1, long term seal energy-saving piston ring, it includes ring body (1) and ring body splaying (6).It is characterized in that the ring body two ends are shaped on arc bolt piece (2) and arc bolt mouth (3) respectively.

2, as claim 1, described long term seal energy-saving piston ring, it is characterized in that the external lower margin in ring body one end is shaped on arc bolt mouth (3), inward flange has a vertical ringwall (4) that links to each other with ring body, and top edge has a ring eaves (5).

3, long term seal energy-saving piston ring as claimed in claim 1 is characterized in that arc bolt piece (2) is positioned at the external lower margin of ring body the other end, and links to each other with ring body, shape, size and the shape of arc bolt mouth (3), big or small identical.
