Abstract

The utility model provides special-shaped double-peak seal ring which comprises a seal ring body as well as a first peak and a second peak which are positioned above the seal ring body, wherein a groove is arranged between the first peak and the second peak; the section of the first peak is the shape of a right triangle; the section of the second peak is the shape of an isosceles triangle; and one side of the first peak, close to the second peak, is a right-angle side. The special-shaped double-peak seal ring has the beneficial effects that by utilizing the technical scheme, the leakproofness and firmness in connection are guaranteed, the project construction is smoother, and the quality potential is reduced.

Description

The bimodal seal ring of a kind of abnormity

Technical field

The utility model belongs to the water and wastewater piping engineering technical field, especially relates to a kind of special-shaped bimodal seal ring that connects double-wall corrugated pipeline, belongs to elastomer seal.

Background technique

At present, bury ground draining use the plastic pipe industry, the peak shape of the bimodal seal ring of known double-wall corrugated pipeline is even distributable type.Notice of authorization number has disclosed a kind of multiple spot lip PE double-wall corrugated pipe special sealing ring for the Chinese patent of CN201396549Y; Though in design, match with the tubing waveform; Realized the better seal effect, but under the slightly little situation of pipeline bellmouth, caused seal ring distortion turnover easily even bellmouth is broken.

Summary of the invention

The purpose of the utility model is the deficiency that overcomes existing technology, and a kind of requirement that can not only satisfy sealing is provided, and can guarantee to connect the special-shaped bimodal seal ring of smoothness and soundness.

The technological scheme of the utility model is: the bimodal seal ring of a kind of abnormity, and comprise the seal ring body and be positioned at the first peak and second peak on the seal ring body, be provided with groove between the said first peak and second peak; The rectangular triangle in said first peak cross section; Cross section, said second peak is isosceles triangle; Said first peak is a right angle side near a side at second peak.

The height at the height of said first peak and second peak equates.

The width in said first peak cross section is less than the width in cross section, second peak, and preferable width is 3/4ths of second peak width.

The bimodal seal ring of said abnormity is a rubber ring.

Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, in the seal and fastness that guarantee to connect, make engineering construction more smooth and easy, reduce hidden danger of quality.

Embodiment

As shown in Figure 1, the bimodal seal ring of a kind of abnormity of the utility model comprises seal ring body 3 and is positioned at the first peak 1 and second peak 2 on the seal ring body 3 that seal ring body 3 is upwards broadened by the bottom gradually, is provided with groove 4 between the first peak 1 and second peak 2; The rectangular triangle in first peak 1 cross section; 2 cross sections, second peak are isosceles triangle; First peak 1 is a right angle side near a side at second peak 2, and the height at the height of first peak 1 and second peak 2 equates; The width in first peak 1 cross section is less than the width in 2 cross sections, second peak, and preferable width is 3/4ths of second peak, 2 width.The bimodal seal ring of abnormity can adopt rubber ring.

In use, as shown in Figure 2, special-shaped bimodal seal ring is inserted in the wave trough position of double-wall corrugated pipe 5 terminations; Make first peak 1 be in double-wall corrugated pipe 5 termination sides; The double-wall corrugated pipe 5 termination socket joints that are with special-shaped bimodal seal ring are gone into double-wall corrugated tube faucet 6, accomplish the connection of double-wall corrugated pipe 5, because first peak 1 forward active force reduction than second peak 2; Make seal ring be easy to get into double-wall corrugated tube faucet 6 parts, the soundness that second peak, 2 configurations do not change and connect to guarantee.

More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
