Abstract
The utility model discloses a crossing wall pipeline sealing ring which is made of elastomer. A circular groove whose cross section is rectangular is arranged on the external circumference of the elastomer sealing ring along the circumference direction. The width of the notch of the circular groove is fitted with the size of a wall surface thickness of a pipeline passing through the wall surface. The internal circumference of the elastomer sealing ring is in the shape of cylindrical surface. The internal diameter of the cylindrical surface of the internal circumference of the elastomer sealing ring is fitted with the size of the external diameter of the pipeline. Sealing lines whose cross section is triangular are arranged on the cylindrical surface of the internal circumference of the elastomer sealing ring along the circumference direction. A circular groove whose cross section is rectangular is arranged on the external circumference of the utility model along the circumference direction. Sealing lines whose cross section is triangular are arranged on the cylindrical surface of the internal circumference along the circumference direction. The utility model can be installed between the pipeline of the crossing wall pipeline and the wall surface, which realizes the seal between the pipeline and thewall surface. Because the utility model is made of elastomer, the crossing wall pipeline sealing ring has the advantages of easy installation, strong corrosion resistance, lower fabrication cost and good sealing performance.
Description
Technical field
The utility model relates to a kind of pipeline of wall and seal ring between wall of passing.
Background technique
In the occasion that some pipeline passes wall, requiring has better seal between pipeline and wall.As be embedded in underground distribution reservoir, branch family water meter is arranged in the distribution reservoir, the outlet conduit of branch family water meter will pass the wall of distribution reservoir to the user, pass between the pipeline of wall and wall and have certain clearance, since distribution reservoir be embedded in underground, the gas of underground water and underground humidity might enter from the gap between pipeline and wall in the distribution reservoir, for the gas that prevents underground water and underground humidity enters in the distribution reservoir by the gap between the pipeline wall, between pipeline and wall seal ring will be installed.In the prior art, the seal ring of useful stainless steel, not only cost is higher for this stainless steel seal ring, and sealing effect is also bad.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, and it is lower to propose a kind of cost, the crossing wall pipeline seal ring of good sealing effect.
The utility model is realized with the following method.
The crossing wall pipeline seal ring is the seal ring made from elastomer, excircle at the elastomeric seal ring, it is the annular groove of rectangle that cross section is along the circumferential direction arranged, the axis of the cylndrical surface at the place, bottom surface of annular groove and the axis of elastomeric seal ring are on same straight line, the plane, place, side of annular groove and the axis of elastomeric seal ring are perpendicular, the width of rebate of annular groove is the size that matches with the thickness of the wall that pipeline will pass, the inner circumference of elastomeric seal ring is a cylindrical so, the axis of the axis of inner circumference cylndrical surface and elastomeric seal ring is on same straight line, the internal diameter of elastomeric seal ring inner circumference cylndrical surface is the size that matches with the external diameter of pipeline, and it is leg-of-mutton potted line that cross section is along the circumferential direction arranged on the inner circumference cylndrical surface of elastomeric seal ring.
During use, on the wall that pipeline will pass, open a circular hole with the equal diameters of the annulus at the place, bottom surface of annular groove of the present utility model, the utility model is set in the circular hole, allow the internal circle edge of circular hole be inserted in the annular groove of the present utility model, allow pipeline pass cylndrical surface of the present utility model inner circumference.
Excircle of the present utility model, along the circumferential direction cross section to be arranged be the annular groove of rectangle, on the inner circumference cylndrical surface, along the circumferential direction cross section to be arranged be leg-of-mutton potted line, the utility model can be installed between the pipeline and wall of crossing wall pipeline, realize the sealing between pipeline and wall, because the utility model is to make with elastomer, simple installation, corrosion resistance is strong, cost is lower, good sealing effect.In installing engineering, has bigger application prospect.
Below in conjunction with accompanying drawing, the utility model is further described.
Description of drawings
Fig. 1 is that the master of crossing wall pipeline seal ring looks and partly cuts open schematic representation;
Fig. 2 is that schematic representation is partly cutd open in the side-looking of Fig. 1.
Embodiment
Fig. 1, among Fig. 2, the crossing wall pipeline seal ring is the seal ring made from elastomer 1, excircle at the elastomeric seal ring, it is the annular groove 2 of rectangle that cross section is along the circumferential direction arranged, the axis of the cylndrical surface at 3 places, bottom surface of annular groove and the axis 4 of elastomeric seal ring are on same straight line, the plane, 5 place, side of annular groove and the axis of elastomeric seal ring are perpendicular, the width of rebate of annular groove is the size that matches with the thickness of the wall that pipeline will pass, the inner circumference 6 of elastomeric seal ring is a cylindrical so, the axis of inner circumference cylndrical surface and elastomeric seal ring is on same straight line, the internal diameter of elastomeric seal ring inner circumference cylndrical surface is the size that matches with the external diameter of pipeline, and it is leg-of-mutton potted line 7 that cross section is along the circumferential direction arranged on the inner circumference cylndrical surface of elastomeric seal ring.
Distance between the cylndrical surface at the place, bottom surface of the annular groove of above-mentioned crossing wall pipeline seal ring and seal ring inner circumference cylndrical surface is 3～5 millimeters.
The elastomer of above-mentioned seal ring can be rubber material, soft plastic material or rubber and plastic material.
