Abstract

The utility model discloses a fixed rubber ring's AGR pipe, including tube head, rubber ring and pipe tail, the tube head internal diameter is the same with pipe tail external diameter, be equipped with on the tube head with the endocentric uplift of tube head, the body cladding is in the uplift, and the body inner wall is parallel with the tube head inner wall, and the body inner wall is equipped with cyclic annular flange and elasticity and seals the ring, cyclic annular flange perpendicular to the body inner wall, elasticity seal the ring tangent plane and be the wedge, and the slope is followed the pipe tail direction slope. The utility model has the advantages that: the utility model discloses fix the rubber ring in the tube head, cyclic annular flange and elasticity seal ring diameter ratio tube tail external diameter are little slightly, and after the tube tail inserted the tube head, cyclic annular flange can cramp the tube tail, and wedge elasticity seal ring is because the inclined plane is along the setting of tube tail direction, and the tube tail inserts back elasticity seal ring and can prevent that the tube tail from withdrawing from, has and prevents moving back sealed function, the utility model discloses AGR pipe leakproofness is good, need not other auxiliary materials, convenient construction.

Description

AGR pipe of fixed rubber ring

Technical Field

The utility model relates to a field especially relates to a AGR pipe of fixed rubber ring.

Background

Agr (acrylic Graft resin) is a novel resin material prepared by fully mixing ultrafine acrylic elastomer into polyvinyl chloride molecules in a chemical copolymerization and combination mode, and the name of the agr (acrylic Graft resin) is acrylic copolymer polyvinyl chloride. The material has excellent impact resistance and low temperature resistance (less than or equal to minus 10 ℃), is safe, sanitary, stable and reliable, has long service life, has quality completely meeting the requirement of the drinking clean water pipe standard of the national ministry of health, and is one of the water supply pipes preferred by urban and rural high-standard water supply networks, national large-scale basic engineering and permanent engineering.

Compared with pipelines such as PP-R, PE, the AGR pipeline is not easy to deform due to heat, is suitable for both open installation and concealed installation, needs few supports in the construction process, is attractive, and has low construction cost. The high rigidity also ensures that the AGR pipe fitting can bear larger pressure resistance, the wall thickness of the AGR pipe fitting is thinner than that of pipelines such as PP-R, PE and the like under the condition of equal pressure, and the same water flow can be achieved by using the AGR pipeline with smaller pipe diameter, so that the cost can be saved and the installation efficiency can be improved.

For the convenience of connection, the two ends of the pipeline are generally designed to be insertable, that is, one end of the pipeline is expanded, the other end of the pipeline of the same type is inserted, and then the joint is sealed by using sealing paint. The pipeline connection mode is difficult to construct, leakage is easy to occur, and pollution is also generated in the pipeline.

SUMMERY OF THE UTILITY MODEL

The utility model discloses to the poor problem of current pipeline connection effect, provide a AGR pipe of solid fixed rubber ring.

The utility model provides an above-mentioned technical problem's technical scheme as follows: the utility model provides a AGR pipe of fixed rubber ring, includes tube head, rubber ring and pipe tail, its characterized in that, the tube head internal diameter is the same with pipe tail external diameter, be equipped with on the tube head with the endocentric uplift of tube head, the body cladding is in the uplift, the body inner wall with the tube head inner wall is parallel, the body inner wall is equipped with cyclic annular flange and elasticity and seals the ring, cyclic annular flange perpendicular to the body inner wall, elasticity seals the ring tangent plane and is the wedge, and the inclined plane is followed the slope of pipe tail direction slope.

The utility model has the advantages that: the utility model discloses fix the rubber ring in the tube head, cyclic annular flange and elasticity seal ring diameter ratio tube tail external diameter are little, and after the tube tail inserted the tube head, cyclic annular flange can cramp the tube tail, and wedge elasticity seal ring is because the inclined plane sets up along the tube tail direction, and the tube tail inserts back elasticity seal ring and can prevent that the tube tail from withdrawing from, has and prevents moving back sealed function. The utility model discloses AGR pipe leakproofness is good, need not other auxiliary materials, convenient construction.

Furthermore, the included angle between the inclined plane of the elastic sealing ring and the inner wall of the pipe head is 15-30 degrees.

Furthermore, the body is uniformly provided with slotted holes. The utility model discloses the AGR pipe is under uncooled molten state with the rubber ring cladding in the uplift, sets up the slotted hole on the body, and the fuse-element gets into to make the rubber ring fixed better firm after the slotted hole cooling, is difficult for droing.
