Detailed Description

As shown in fig. 1-6, a hough section repairing device comprises two hough section half bodies 10 which are enclosed to form a hough pipe section, wherein a straight groove 11 arranged on the axial side edge of the hough section half body 10 and an arc-shaped groove 12 circumferentially arranged at the end part of the hough section half body 10 are respectively used for embedding a sealing element straight section 21 and a sealing element arc section 22 of a sealing element half body 20, the sealing element straight sections 21 respectively exposed outside the straight groove 11 of the hough section half body 10 are pressed mutually, the sealing element arc sections 22 respectively exposed outside the arc-shaped groove 12 of the hough section half body 10 are enclosed and extruded on the pipe wall of a pipeline a to be repaired, an embedded convex rib groove type fit is formed between the groove bottom of the arc-shaped groove 12 and a corresponding binding surface of the sealing element arc section 22 arranged in the arc-shaped groove 12, and the length direction of a convex rib or groove is consistent with the arc direction of the arc-shaped groove 12.

When the pipeline A is damaged and leaked, the two half-half-half Haff sections 10 embedded with the half-half sealing element 20 are covered on the periphery of the pipeline A, at the moment, the two straight sections 21 of the sealing element are pressed mutually, the two arc sections 22 of the sealing element are encircled and extruded on the pipe wall of the pipeline A to be repaired, the leakage point is enclosed and blocked, and the bottom of the arc-shaped groove 12 and the corresponding binding surface of the arc-shaped section 22 of the sealing element arranged in the arc-shaped groove 12 form embedded convex rib groove type matching, so that the axial positions of the half sealing element body 20 and the half Haff section body 10 are limited, the half sealing element body 20 is prevented from being misplaced or even falling off under the water flow impact, meanwhile, the half sealing element body 20 is prevented from being bonded by glue, and the water pipe sealing device is more environment-friendly and can be suitable for repairing drinking water pipes. Three scenarios are included here: in the first scheme, the convex rib is arranged on the bottom of the arc-shaped groove 12, and the groove is arranged on the outer peripheral surface of the arc-shaped section 22 of the sealing element; in the second scheme, the convex rib is arranged on the outer peripheral surface of the arc-shaped section 22 of the sealing element, and the groove is arranged on the bottom of the arc-shaped groove 12; according to the third scheme, the outer peripheral surface of the arc-shaped section 22 of the sealing element is provided with a convex rib and a groove, and the bottom of the arc-shaped groove 12 is provided with a groove and a convex rib; as the case may be.

Compared with the technical scheme in the document 1, instead of providing a plurality of radial seal grooves on the half-half haff joint 10 and providing radial seal bodies between the radial seal bodies at the end parts in addition to the radial seal bodies at the two ends, a middle seal structure is omitted, an arc-shaped groove 12 is only provided at the end part of the half haff joint 10, and an embedded convex rib groove type fit is formed between the groove bottom of the arc-shaped groove 12 and a bonding surface corresponding to an arc-shaped section 22 of the seal member arranged in the arc-shaped groove 12, and during installation, only the arc-shaped section 22 of the seal member 20 which is soft is required to be installed in place with the arc-shaped groove 12, so that the structural stability of the half-half haff joint is ensured on the premise of ensuring high sealing performance, the assembling steps are simple and many, and the repair time of the pipeline a is greatly shortened.

As the preferred embodiment of the present invention, the groove bottom of the arc-shaped groove 12 is provided with the convex rib 121 protruding from the flat groove bottom of the flat groove bottom, and the concave portion 221 corresponding to the convex rib 121 is provided in the periphery of the arc-shaped section 22 of the sealing member, considering the processing problem and the convenient factor of assembly, the first preferred embodiment herein.

In order to ensure the positioning reliability, the rib 121 is arranged at the middle position of the groove bottom of the arc-shaped groove 12, and correspondingly, the concave part 221 is arranged at the middle position of the arc-shaped section 22 of the sealing element.

The inner side edge of the sealing element straight section 21 is formed by an external flange 211, a clamping groove 222 is formed between the flange 211 and the inner wall of the sealing element straight section 21, and the clamping groove 222 is clamped on the edge of the inner side groove wall of the straight groove 11. The flange 211 and the body part of the sealing element straight section 21 are of an integrated structure, after the flange 211 is additionally arranged, the contact area between the periphery of the inner side of the sealing element straight section 21 and the half-half-body 10 can be increased, on one hand, the sealing element half body 20 plays a role in clamping and fixing, so that the stability of the sealing element half body 20 is better, on the other hand, the sealing effect of the sealing element half body 20 can be improved, and the pipeline repairing device has stronger pressure resistance.

The intrados of the seal arcuate segment 22 is provided with a toothed seal 223. The cross section of the tooth-shaped sealing part 223 can be isosceles teeth or right-angle teeth with right-angle sides facing the repaired part, so that an anti-skid sealing structure is formed.

The two ends of the arc-shaped groove 12 are in a dovetail groove structure with a small notch and a large groove bottom, so that the sealing element half body 20 is further prevented from falling off.

The two ends of the inner diameter of the arc-shaped section 22 of the sealing element protrude out of the binding surface of the half-half huff section 10, and the two ends of the outer diameter of the arc-shaped section 22 of the sealing element are flush with the binding surface of the straight section 21 of the sealing element to form a wedge-shaped sealing end 23. Because this position is the junction of sealing member straight section 21 and sealing member arc section 22, and this rubber thickness is the biggest, consequently the probably compression sealing force of this department is not enough after other positions accomplish compression sealing, consequently sets up wedge seal end 23 at this position and has formed wedge compensation compression structure, and the side of wedge seal end 23 can be triangle-shaped or trapezium structure, avoids hough festival both ends to leak because of the local that the compression is not enough causes.

Further ensuring the sealing reliability, and a sealing flat gasket 30 is arranged between the pressing surfaces of the two sealing element half bodies 20 in a cushioning mode, so that the possibility of leakage is eliminated.

In order to realize the connection between the two half-huff sections 10, the outer walls of the two half-huff sections 10 are provided with connecting parts 13 along the axial direction at intervals, and in view of the fact that a gas or liquid medium exists in the damaged pipeline A and the pressure is possibly appropriate, one half-huff section 10 is further provided with a pressure relief opening 14, so that the half-huff sections can be conveniently connected, and then the pressure relief opening 14 is plugged by a plug.
