Abstract

The utility model provides a high elastic gasket, includes the oval -shaped sealing ring, and the sealing ring is become by the last ring body of arc and convex runner band body group, and the inside and outside circle of last ring body is in the same place with the inside and outside ring of welded fastening who descends the ring body respectively, internal and the internal distribution of runner band of fitting with a contraceptive ring is pegged graft has magnet ring under the last magnet ring sum, goes up under the magnet ring sum magnet ring and repels each other and press respectively on last ring body and ring body down, and it has a plurality of counter bores to go up on the terminal surface that the magnet ring is relative under the magnet ring sum shaping respectively, and the upper end of spacing post is pegged graft in the counter bore that last magnet encircled, in the lower extreme grafting counter bore that magnet encircled under, cladding rubber sleeve circle on the surface of last ring body and lower ring body. It establishs oval -shaped flexure strip structure continuously to put forward ammunition feed power for the rubber pad at the rubber pad, increases sealing rubber pad's sealing performance, reduces the emergence of leaking.

Description

A kind of high resiliency sealing gasket

Technical field：

This utility model is related to the technical field of seal connector, more specifically to a kind of high resiliency sealing gasket.

Background technology：

At present in some chemical industry, the industry of pharmacy, its medicinal liquid is conveyed by pipeline, and its pipeline is generally and splices Pipeline, the mouth of pipe of its pipeline forms flange, thus being attached by bolt assembly, and in order to ensure between pipeline Sealing, can add rubber washer between the flanges；And rubber washer is subject to such environmental effects very big, appearance of being such as heated is shunk, and goes out The flange of existing rubber washer and pipeline is not fitted, then be easy for leaking.

Utility model content：

The purpose of this utility model is aiming at the deficiency of prior art, and provides a kind of high resiliency sealing gasket, its energy Increase the sealing property of sealing rubber pad, reduce the generation of leakage.

A kind of high resiliency sealing gasket, including oval sealing ring, sealing ring is by the upper ring body of circular arc and circular arc Lower ring body forms, and the inside and outside circle of upper ring body is welded and fixed together with the inside and outside circle of lower ring body respectively, in described upper ring body and In lower ring body, distribution is plugged with upper magnet ring and lower magnet ring, and upper magnet ring and lower magnet ring repel each other and press up against upper ring body On lower ring body, the upper magnet ring end face relative with lower magnet ring forms some counterbores, the upper end grafting of limited post respectively In the counterbore of upper magnet ring, lower end is plugged in the counterbore of lower magnet ring；Wrap on the outer surface of described upper ring body and lower ring body It is covered with rubbery loop.

The ellipsoidal cross section of described rubbery loop, rubbery loop is non-enclosed lasso, the outer ring molding of rubbery loop There is grooving, rubbery loop is pasted and fixed on upper ring body and the outer surface of lower ring body.

Described counterbore is ringwise evenly distributed on upper magnet ring or lower magnet ring.

The deep equality of the counterbore on counterbore and lower magnet ring on described upper magnet ring, the length of limited post is less than upper magnetic The distance of the bottom surface of counterbore to lower magnet ring counterbore bottom surface on iron hoop, the length of limited post is more than upper magnet ring lower surface to lower magnetic The distance of iron hoop counterbore bottom surface.

The beneficial effects of the utility model are：

1st, the elastic chip architecture that it sets up ellipse in rubber blanket persistently provides elastic force for rubber blanket, increases sealing rubber pad Sealing property, reduce leakage generation.

2nd, in its rubber blanket, elastic chip architecture is provided with position limiting structure, is avoided that flexure strip oversteps the extreme limit active force and occurs Elastic failure.

Specific embodiment：

Embodiment：As shown in Fig. 1 to 3, a kind of high resiliency sealing gasket, including oval sealing ring, sealing ring is by circular arc The lower ring body 2 of the upper ring body 1 of shape and circular arc forms, and the inside and outside circle of upper ring body 1 connects with the inside and outside lap welding of lower ring body 2 admittedly respectively Be scheduled on together, distribution in described upper ring body 1 and in lower ring body 2 is plugged with upper magnet ring 3 and lower magnet ring 4, upper magnet ring 3 and under Magnet ring 4 repels each other and presses up against on upper ring body 1 and lower ring body 2, and upper magnet ring 3 end face relative with lower magnet ring 4 divides Do not form some counterbore a, the upper end of limited post 5 is plugged in the counterbore a of upper magnet ring 3, lower end is plugged on lower magnet ring 4 In counterbore a；It is coated with rubbery loop 6 on the outer surface of described upper ring body 1 and lower ring body 2.

The ellipsoidal cross section of described rubbery loop 6, rubbery loop 6 is non-enclosed lasso, and the outer ring of rubbery loop 6 becomes Type has grooving 61, and rubbery loop 6 is pasted and fixed on upper ring body 1 and the outer surface of lower ring body 2.

Described counterbore a is ringwise evenly distributed on upper magnet ring 3 or lower magnet ring 4.

The deep equality of the counterbore a on counterbore a and lower magnet ring 4 on described upper magnet ring 3, the length of limited post 5 is little The distance of the bottom surface of counterbore a to lower magnet ring 4 counterbore a bottom surface on upper magnet ring 3, the length of limited post 5 is more than upper magnet ring 3 The distance of lower surface to lower magnet ring 4 counterbore a bottom surface.

Operation principle：This utility model is oval caulking gum packing ring, and feature is its rubber washer (i.e. rubber sleeve Circle 6) in be provided with ellipse flexure strip (i.e. upper ring body 1 and lower ring body 2 composition sealing ring), the pressurized meeting of its flexure strip itself Produce elasticity, its interior upper magnet ring 3 and lower magnet ring 4 produce active force by flexure strip simultaneously, so that flexure strip is possessed high-elastic Property, can be continuously rubber blanket provides elastic force, realizes excellent sealing；Between upper magnet ring 3 and lower magnet ring 4, setting limits again simultaneously Position post 5, can avoid flexure strip to be depressed beyond the limit of elastic deformation, it is to avoid flexure strip elastic failure.
