Description

Rubber sealing ring

Technical Field

The utility model relates to a pipe seal device field, concretely relates to rubber seal.

Background

In the prior art, a sealing ring is generally adopted as a sealing system for pipeline connection in pipeline connection, the sealing ring is sleeved into the end parts of two connecting pipelines, and two external half circular pipe cards are fastened through bolts to realize steel pipe sealing connection. The diameter of the sealing lip surface of the sealing ring is based on the outer diameter of the steel pipe, the larger the medium pressure is, the tighter the sealing is, and the sealing ring can realize the sealing of the vacuum pipeline and the pressure pipeline.

Chinese patent CN201020573739.9 discloses a pipe socket, wherein an annular rubber ring is composed of an outer ring and an inner ring, one edge of the inner ring is connected with the outer ring as a whole, the inner ring is a conical ring in a natural state, the outer ring is provided with a circle of convex edges, and the convex edges are arranged at the connection position of the inner ring and the outer ring. The utility model discloses an inner circle is cylindrical ring under the user state, and the outer lane is engaged with the cast iron pipe bellmouth, and after the cast iron pipe socket inserted the inner circle, made the inner circle warp and compress the outer lane, warp through rubber and reach sealed effect.

However, due to long-term use and environmental changes of the pipeline, the pipeline and the sealing element thereof are easy to deform, and the maintenance and replacement cost at the later stage is greatly increased.

SUMMERY OF THE UTILITY MODEL

The utility model is directed to the above problem, a rubber seal that simple structure, leakproofness are strong is provided.

The utility model provides a technical scheme that above-mentioned problem adopted is:

the utility model provides a rubber seal, includes retainer plate layer and rubber ring layer, be equipped with a plurality of bosss on the retainer plate layer, rubber ring layer bottom symmetry is equipped with a plurality of recesses, retainer plate layer and rubber ring layer adaptation joint.

Furthermore, a stop block is arranged in the middle of the upper portion of the rubber ring layer, and annular oblique edges which are inclined inwards are symmetrically arranged on two sides of the stop block.

Furthermore, a reinforcing lug is further arranged on one side of the fixing ring layer and forms a clamping groove with the boss, and the reinforcing lug is used for reinforcing the clamping connection of the fixing ring layer and the rubber ring layer.

Furthermore, the fixed ring layer and the required butt joint pipe outer pipe are integrally formed.

The utility model has the advantages that:

1. the utility model has convenient installation, and the structure is firmer and is not easy to loose and break away through the clamping of the fixed ring layer and the rubber ring layer;

2. the utility model has long service life and is not easily influenced by environment and deformation;

3. the utility model has the advantages of easy manufacture, stable structure and durability.

In addition to the above-described objects, features and advantages, the present invention has other objects, features and advantages. The present invention will be described in further detail with reference to the drawings.
