Description
Technical field
The utility model relates to a kind of assembling pipe joint, particularly relates to a kind of connection set that heavy caliber (diameter more than or equal to 90mm, as follows) polyvinyl plastics pipeline uses that is used to connect.
Background technique
The connection of general employing flange, gluing connecing with hot melt are connected between the existing heavy caliber vinyl tube.
Flange connects and to receive the influence of packing ring and can not give full play to its pressure, make tube fluid (liquid/gas) medium fully not isolate with the external world; Be subject to the influence of effects such as thermalization influence, dielectric corrosion and resonance destroy, have short, shortcomings such as anti-leakage is poor, sealing effect difference of operation cycle.
Gluing connect have that join strength is not high, poor reliability, construction intensity is big, efficient is low, technology shortcoming such as complicacy comparatively.
Hot melt connect exist technological requirement high, to professional skill require high, welding to the restriction of temperature rise, can not use shortcoming such as the anticorrosion or high-abrasive material of thermoplasticity.
Above-mentioned several kinds of Placements are only applicable to conventional execution conditions; Be difficult to be applicable to unconventional execution conditions; Like the end, lake (storehouse), seabed and the mountain region etc. of complicated topographical conditions, and still there is not the polyvinyl plastics pipe connection that is specially adapted for these unconventional execution conditions at present.
The model utility content
The purpose of the utility model provides a kind of simple in structure, low cost of manufacture, connection is reliable, installations is simple and direct and sealing is strong heavy caliber polyvinyl plastics pipe connection, and this connection set is applicable to being connected between the heavy caliber vinyl tube under routine and the unconventional execution conditions.
To achieve these goals, the technological scheme that the utility model is taked is following: a kind of heavy caliber polyvinyl plastics pipe connection comprises the bolt of connected two sections vinyl tubes, flange plate and mounting flanges; It is characterized in that: the polyvinyl plastics tube opening is provided with flange, and this connection set also comprises internal lining pipe, pressure ring, sleeve pipe and seal ring; Internal lining pipe outer wall middle part is provided with convexity; Internal lining pipe is positioned at two sections vinyl tubes; Convexity is positioned at two sections vinyl tube connecting ports, internal lining pipe external diameter and polyvinyl plastics bore adaptive and with the vinyl tube stationary fit, seal ring is installed in protruding both sides; Pressure ring is installed at flange reducing place, and pressure ring internal diameter and polyvinyl plastics external diameter of pipe are adaptive; Flange and pressure ring outside mounting sleeve, casing inner diameter and flange outside diameter are adaptive; Flange plate is installed in the sleeve pipe two ends.
The convexity that the utility model is provided with through physical action crush seal circle and internal lining pipe middle part is to reach tube fluid (liquid/gas) and the extraneous effect of cutting off; Be applicable to being connected of heavy caliber vinyl tube under conventional and the unconventional execution conditions, compare with traditional Placement have good sealing effect, long service life, simple in structure, characteristics such as making is easy, easy for installation, quick.
Description of drawings
Fig. 1 is the structural relation schematic representation of the utility model.
Among the figure: 1-internal lining pipe, 101-convexity, 2-pressure ring, 3-sleeve pipe, 4-seal ring, 5-flange plate, 6-bolt, 7-vinyl tube, 701-flange.
Embodiment
Through accompanying drawing, the utility model is done further detailed description below.As shown in the figure: a kind of heavy caliber polyvinyl plastics pipe connection comprises the bolt 6 of connected two sections vinyl tubes 7, flange plate 5 and mounting flange; The polyvinyl plastics tube opening is provided with flange 701, and this connection set also comprises internal lining pipe 1, pressure ring 2, sleeve pipe 3 and seal ring 4; Internal lining pipe 1 outer wall middle part is provided with protruding 101; Internal lining pipe 1 is positioned at two sections vinyl tubes 7; Protruding 101 are positioned at two sections vinyl tube 7 connecting ports, internal lining pipe 1 external diameter and vinyl tube 7 internal diameters adaptive and with vinyl tube 7 stationary fits, protruding 101 both sides installation seal ring 4; Pressure ring 2 is installed at flange 701 reducing places, and pressure ring 2 internal diameters and vinyl tube 7 external diameters are adaptive; Flange 701 and pressure ring 2 outside mounting sleeves 3, sleeve pipe 3 internal diameters and flange 701 external diameters are adaptive; Flange plate 5 is installed in sleeve pipe 3 two ends.
Seal ring 4 is the rubber material, and internal lining pipe 1, pressure ring 2, sleeve pipe 3 etc. are stainless steel; Sleeve pipe 3 is the corrugated bushings with resiliently deformable; Protruding 101 width are about 10mm, are generally 10～15mm; Seal diameter is not less than 5mm, is generally 5～15mm.
The flange 701 that the polyvinyl plastics tube opening is provided with, unnecessary processing factory at vinyl tube makes.Vinyl tube is the port common polythene plastic tube consistent with main body caliber and shape, behind process that two sections vinyl tubes 7 is connected heating and follow-up assembling internal lining pipe, forms flange 701.
The connecting end preheating of two sections vinyl tubes that before assembling, will connect earlier; Then immediately two sections vinyl tubes are enclosed within on the stainless steel inner lining tube; After being set to stainless steel inner lining tube to vinyl tube, form flange in the vinyl tube port; Both sides at internal lining pipe intermediate annular high spot add seal ring; The mounting flange at the reducing place, flange both sides of vinyl tube; Press ring in the flange plate; The pressure ring outside adds the corrugated bushing with resiliently deformable, in order to protection pressure ring and auxiliary seal, at last with bolt with the fastening connection purpose that reaches of flange plate.
