Abstract
The utility model relates to a metallic reinforced polyethylene composite socket and faucet joint, which consists of a socket head and a faucet head. The utility model is characterized in that the socket head is of a straight-round shape. A groove is arranged inside the socket hole of the faucet head and a sealing ring is arranged inside the groove. The outside diameter of the socket head is slightly smaller than the inside diameter of the socket hole. With a socket and faucet joint arranged on both ends of a steel-strip reinforced polyethylene helical corrugated pipe, the metallic reinforced polyethylene composite socket and faucet joint has the advantages that the connection between pipes is made rapidly and conveniently, the sealing effect is excellent, the joint strength is enhanced and the cost is saved.
Description
Technical field
The utility model relates to a kind of metal and strengthens the compound bell and spigot joint of polyethylene.Particularly a kind of bell and spigot joint of being located at the steel band reinforced polyethylene spiral ripple pipe two ends.
Background technique
From in recent years, steel band reinforced polyethylene spiral ripple pipe maintains the leading position at the large-bore plastics pipeline with high ring rigidity, high performance-price ratio China's large-bore plastics pipeline in development.But because pipe structure factor, the Placement that tubing adopts at present is that hot melt is extruded to be welded to connect with the electric smelting band and is connected, these two kinds of connecting means are affected by environment very big when construction and installation, as water or soft sandy soil, in addition because of tube end face twist, the port of pipe is difficult for alignment during installation, causes that the tubing installation rate is slow, construction cost is high.
Summary of the invention
The purpose of this utility model, be to provide a kind of metal to strengthen the compound bell and spigot joint of polyethylene, bell and spigot joint is divided into the two ends of composite screw bellows, has strengthened the heavy caliber pipe joint strength, has also solved composite screw bellows end face injustice and the difficult problem that connects.Construction is simple, connects fast, and good sealing effect.
A kind of metal described in the utility model strengthens the compound bell and spigot joint of polyethylene, and it comprises socket joint head and bellmouth head, it is characterized in that: the socket joint head is for straight circular; Be provided with groove in the socket joint hole of bellmouth head, seal ring is set in the groove; The external diameter of socket joint head is small in the internal diameter in socket joint hole.
In order to make the connecting part good sealing effect of two tubing, be provided with two circles or a circle groove in the socket joint hole of bellmouth head, high elastic rubber seal ring and hydro-expansive rubber seal ring or any one seal ring wherein are set respectively.
In order to improve the intensity of tube connector, the metal surface of socket joint head and bellmouth head innermost layer is followed successively by adhering resin layer and polyethylene layer from inside to outside.
For smooth and easy in the two tubing jointing pipes, the socket joint hole of bellmouth head is an enlarging, and the size of its expansion equals the tube wall size of socket joint head.
The beneficial effects of the utility model are, owing to be provided with bell and spigot joint at the steel band reinforced polyethylene spiral ripple pipe two ends, make that the connection between the tubing is efficient and convenient, and good sealing effect, and joint strength improves, and save cost.
Description of drawings
Fig. 1 is the utility model cut-away view.
Fig. 2 is the mutual socket joint cut-away views of the utility model two pipes.
Among the figure: 1. the socket joint head is straight circular, 2. bellmouth head, 3. socket joint hole, 4. groove, 5. high elastic rubber seal ring, 6. hydro-expansive rubber seal ring, 7. steel plate, 8. enlarging.
Embodiment
A kind of metal described in the utility model strengthens the compound bell and spigot joint of polyethylene, and as depicted in figs. 1 and 2, bell and spigot joint is divided into the steel band reinforced polyethylene spiral ripple pipe two ends, and the socket joint head is straight circular 1; Be provided with in the socket joint hole 3 of bellmouth head 2 high elastic rubber seal ring 5 and hydro-expansive rubber seal ring 6 are set respectively in twice groove 4, two grooves, make sealing effect better; The external diameter of socket joint head 1 is small in the internal diameter in socket joint hole 3, with convenient coincide (as the Fig. 2) that peg graft.
In order to improve the intensity of tube connector, the metal of socket joint head and bellmouth head innermost layer is a steel, steel plate 7 surfaces are followed successively by adhering resin layer and polyethylene layer from inside to outside, just coat the adhering resin layer earlier in the upper and lower surface of steel plate, coat polyethylene layer again, make the jointing of tubing like this, firmer and have more antiseptic effect.The socket joint hole of bellmouth head is an enlarging 8, and the size of its expansion equals the tube wall size of socket joint head.Such two tubing pipe inner joint places are smooth smooth and easy.The utility model good airproof performance, sturdy and durable, the convenient installation saved cost.
