Description

Water-closing sealing ring for corrugated pipe sleeve connection

Technical Field

The utility model relates to a sealing washer field especially relates to a bellows muffjoint is with sealing washer that closes water.

Background

The double-wall corrugated pipe has wide application range in the field of drainage and pollution discharge, and has more connection defects in the long-term use process, such as easy deformation and damage of a socket, difficult settlement resistance of a connection part and easy looseness. The connection can thus be made using a connecting sleeve. In the conventional corrugated pipe connection scheme, the sealing ring can be dislocated, so that a gap or a notch appears at the sealing position, and the sealing effect of the sealing ring is lost. When using connecting sleeve to connect, need design the sealing washer, the sealed effect of guarantee.

The utility model discloses the purpose is to the problem that exists among the background art, provides a bellows muffjoint is with sealing water sealing washer that bearing capacity is strong, difficult dislocation and sealed effectual.

The technical scheme of the utility model is that the water-closing sealing ring for the connection of the corrugated pipe sleeve comprises a rubber ring and spring steel, wherein the rubber ring is of an annular structure; the spring steel is of an annular structure, and the spring steel is embedded in the rubber ring.

Preferably, the rubber ring and the spring steel are both circular ring structures.

Preferably, the spring steel is sheet-like.

Preferably, the rubber ring has an inner peripheral surface and two side surfaces connected with two ends of the inner peripheral surface, and the distance between the two side surfaces is gradually increased along the direction away from the inner peripheral surface.

Preferably, the side surface is provided with a plurality of grooves.

Preferably, the outer peripheral surface of the rubber ring is provided with a positioning clamping groove which is an arc-shaped groove or an annular groove, and when the positioning clamping groove is the arc-shaped groove, the positioning clamping grooves are arranged in a plurality of positions around the rubber ring.

Preferably, the outer peripheral surface of the rubber ring is provided with a tightly-abutting ring line a and a tightly-abutting ring line b which are aligned, and the tightly-abutting ring line a and the tightly-abutting ring line b are contour lines of the radially outermost ends of the rubber ring.

Compared with the prior art, the utility model discloses following profitable technological effect has:

the utility model discloses the bearing capacity is strong, difficult dislocation and sealed effectual. The spring steel is arranged in the rubber ring to support the rubber ring, so that the pressure resistance of the whole sealing ring is improved. The sealing ring can be stably maintained at the mounting position and is not easy to shift or misplace.

Detailed Description

Example one

As shown in fig. 1-4, the water-tight sealing ring for connecting a corrugated pipe sleeve provided by the present invention comprises a rubber ring 1 and spring steel 2, wherein the rubber ring 1 is of an annular structure, and the rubber ring 1 can be made of a silica gel material; spring steel 2 is the loop configuration, and spring steel 2 embedding sets up in rubber ring 1, and spring steel 2 will have excellent creep resistance. The rubber ring 1 and the spring steel 2 are both of circular ring structures, so that coaxial manufacturing is facilitated, and uniformity of pressure resistance is guaranteed. The spring steel 2 is in a sheet shape and can resist pressure in a balanced manner. The rubber ring 1 is provided with an inner peripheral surface 11 and two side surfaces 12 connected with two ends of the inner peripheral surface 11, and the distance between the two side surfaces 12 is gradually increased along the direction away from the inner peripheral surface 11 so as to be adapted to the wave crest structure of the corrugated pipe, fully contact with the wave crest and ensure the sealing effect.

Be provided with positioning groove 13 on the 1 outer peripheral face of rubber ring, positioning groove 13 is arc wall or ring channel, and when positioning groove 13 was the arc wall, positioning groove 13 set up a plurality ofly around rubber ring 1 altogether, and positioning groove 13 can block on the locating piece or the holding ring of preset at the connecting sleeve inner wall to fix a position rubber ring 1's mounted position. The outer peripheral surface of the rubber ring 1 is provided with a tight abutting ring line a141 and a tight abutting ring line b142 which are aligned, the tight abutting ring line a141 and the tight abutting ring line b142 are contour lines of the radial outermost ends of the rubber ring 1, the outer peripheral surface of the rubber ring 1 can gradually change inwards on two sides of the tight abutting ring line, and sealing can be achieved through inward deformation at the two tight abutting ring lines because the rubber ring 1 has certain deformation capacity.

The embodiment has strong bearing capacity, is not easy to misplace and has good sealing effect. The spring steel 2 is arranged in the rubber ring 1 to support the rubber ring 1, so that the pressure resistance of the whole sealing ring is improved. This sealing washer has two kinds of using-way, to a first kind of using-way, can install this sealing washer in advance in connecting sleeve, then with the bellows penetrate connecting sleeve in, the bellows butt carries out waterproof sealing through rubber ring 1 on rubber ring 1. To the second kind of use, can install this sealing washer in advance in the trough department of bellows, then penetrate the bellows in the connecting sleeve, rubber ring 1 seals with the connecting sleeve inner wall. The sealing ring can be stably maintained at the mounting position and is not easy to shift or misplace.

Example two

As shown in fig. 1-4, compared with the first embodiment, the present invention provides a water-sealing ring for bellows sleeve connection, in this embodiment, a plurality of grooves 121 are disposed on the side surface 12, so as to form a plurality of protruding structures, and effectively seal with the bellows in a plurality of places.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made without departing from the gist of the present invention within the scope of knowledge possessed by those skilled in the art.
