the utility model provides a novel stagnant water sealing washer is restoreed in non-excavation part, includes the sealing washer body, its characterized in that: the water retaining ring is characterized by further comprising a steel ring, a circle of water retaining bulges protruding towards the center are arranged at one end of the inner wall of the sealing ring body, the steel ring is formed by curling a steel plate, the steel ring is sleeved in the sealing ring body, one end part of the steel ring abuts against the water retaining bulges, and the ring wall of the steel ring abuts against the inner wall of the sealing ring body.
And, the sealing washer body include rubber body, the two-way water seal structure of single lip, isobaric seal structure and outside tang seal structure, be provided with the two-way water seal structure of single lip at the outer wall middle part bilateral symmetry of rubber body, be provided with isobaric seal structure at the outside interval of two-way water seal structure of single lip, leave the deformation cavity between the two-way water seal structure of single lip and the isobaric seal structure, be equipped with outside tang seal structure on the rubber body outer wall that is equipped with the protruding one end of manger plate.
And the single-lip bidirectional water seal structure is a unilateral water-facing seal structure, and a water storage cavity is reserved between the two single-lip bidirectional water seal structures.
The isobaric sealing structure is composed of a rubber boss and grooves which are arranged on the rubber boss at intervals along the circumferential direction.
And the outer spigot sealing structure is obliquely arranged from inside to outside, and the end part of the outer spigot sealing structure abuts against the inner wall of the pipeline.
The utility model discloses an advantage and beneficial effect do:
1. this novel stagnant water sealing washer is restoreed to non-excavation part combines together through the steel ring that will expand and sealing washer body, has solved the problem that current sealing washer is weak because of the poor sealing ability that leads to of resilience ability. Thereby continuously expand along with the steel sheet and exert pressure with the sealing washer body on laminating the pipeline inner wall of preliminary repair better, then rely on two-way seal lip blade again, change along with the hydraulic pressure and increase radial force, play the effect of axial seal to the stagnant water satisfies local quick prosthetic requirement.
2. This novel stagnant water sealing washer is restoreed to non-excavation part, through the setting of each seal structure, reachs stronger sealed effect. The outside tang is sealed for unilateral meeting water seal, and isobaric seal is two sets of seals side by side, and the two-way water seal of single lip is a set of relative setting, and it can warp along with the change of pressure, plays sealed effect of high efficiency to reach non-excavation local repair's purpose.
3. The utility model has the advantages of structural design scientific and reasonable, have that the resilience is good, waterproof ability is strong, easily realize, applicable in culvert, the restoration pipeline that has certain pathological change, not only have good pressure-bearing nature and leakproofness, can also reach national drainage pipe's acceptance standard, have the road surface of not excavating simultaneously, quick prosthetic advantage is a novel non-excavation local repair stagnant water sealing washer that has higher novelty.
