Chinese patent 200720303343 discloses " quick joint of corrugated pipe " and has comprised bellows, fittings body and attaching nut, and bellows passes the attaching nut, and the attaching nut is threaded with fittings body, and fittings body and attaching nut are metal body.Can there be the hidden danger of metal joint corrosion in elongated along with service time.
The model utility content
The purpose of the utility model provides a kind of electric smelting formula bellows jointing, adopts the project organization of the direct hot melt of polythene material alternative metals material, is metallic material to overcome known technology middle joint main body.
For realizing above-mentioned purpose; The polythene material electric smelting formula bellows jointing that the utility model provides is the tubular body that is shaped to one by jointing and the corrugated pipe injection with certain-length; Tubular body has transition enlarging reducing; The heavy caliber external diameter is identical with combustion gas polyethylene pipe port outside diameter, and small-bore internal diameter is identical with the bellows trough, on the small-bore pipeline external diameter of jointing fixing hoop is arranged; The small-bore pipe of tubular body is external to be arranged with to the location of outer lug snap ring.
In protruding location card hoop bellows direction is conical surface, and protruding location snap ring meets at right angles toward the outer wall and the body of heavy caliber direction.The external diameter of protruding location snap ring is identical with the bigbore external diameter of enlarging reducing.
Fixing hoop is that the semicircle tubular body by two polythene materials is spliced, and all there is the outer body these two semicircle tubular body both sides.Fixing hoop one end is stuck on the small-bore body of electric smelting formula bellows jointing; The other end is stuck on the metal fuel tube body, has the location snap ring of a groove and electric smelting formula bellows jointing to match in an end inside that is stuck in electric smelting formula bellows jointing.On each outer, semicircle tubular body both sides body of fixing hoop, all have 4 screws, each side is respectively 2, passes two screws on the semicircle tubular body opposite position respectively by 4 bolts, with 4 nut check screw lockings that match with it.The groove inner at fixing hoop also has a cement casting screw hole with the centre that is stuck in the port of metal fuel tube, and this cement casting screw hole is furnished with a polythene material plug that matches with it.
After having adopted such structure; When utilizing electric smelting formula bellows jointing that the metal fuel tube is connected with the combustion gas polyethylene pipe; Heavy caliber one end and the electric smelting of combustion gas polyethylene pipe of electric smelting formula bellows jointing are connected, and the fixing hoop through polythene material is locked metal fuel tube and electric smelting formula bellows jointing.
Pour into slush in the cast screw hole of on fixing hoop, being opened then, fill the back and screw with plug.
The utility model connecting tube mode is easier, can carry out electric smelting to pipeline and connect fast, have simple in structure, sealability is strong, no necking down, easy to assembly, the construction convenient.Long service life, the erosion of anti-various chemical mediators.With polythene material alternative metals material, be the optimum scheme that solves the metal joint corrosion.Also known technology is eager to excel in whatever one does relatively for the fixing that connects.
Description of drawings
