Abstract
The utility model relates to a small-bore polyethylene plastic pipe connection device. The device comprises two sections of connected polyethylene plastic pipes, an inner lining pipe, a sleeve, tightening rings and seal rings, wherein a flange is arranged at the port of each polyethylene plastic pipe; the inner lining pipe is positioned in the two sections of the polyethylene plastic pipes, and the outer diameter of the inner lining pipe adapt to the inner diameter of the polyethylene plastic pipes and are in static fit with the polyethylene plastic pipes; a sleeve is arranged outside the two sections of the polyethylene plastic pipes; an annular bump is formed in the middle of the inner wall of the sleeve, the inner diameter of the annular bump adapts to the outer diameter of the flange, and the annular bump corresponds to the assembly position of the flange; the seal rings are arranged at reducing positions of two sides of the annular bump, and the tightening rings are arranged at two ends of the sleeve; the tightening rings are closely contacted with the seal rings; and a flange ring is arranged in the middle of the outer wall of the inner lining pipe, and corresponds with the joint of the two sections of the polyethylene plastic pipes. The small-bore polyethylene plastic pipe connection device has the characteristics of good seal effect, long service life, simple structure and the like, is, easy to manufacture and convenient and quick to assemble, and is suitable for unconventional constriction fields with complicated landform conditions, such as lakebed, seabed, mountainous regions and the like.
Description
Technical field
The utility model relates to a kind of assembling pipe joint, particularly relates to a kind of connection set that small-bore (diameter less than 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, sealing is strong small-bore polyvinyl plastics pipe connection, and this connection set is applicable to conventional and unconventional execution conditions lower small mouth being connected between the vinyl tube directly.
To achieve these goals, the technological scheme that the utility model is taked is following: a kind of small-bore polyvinyl plastics pipe connection comprises connected two sections vinyl tubes; It is characterized in that: the polyvinyl plastics tube opening is provided with flange, and this connection set also comprises internal lining pipe, sleeve pipe, tighten ring and seal ring; Internal lining pipe is positioned at two sections vinyl tubes, internal lining pipe external diameter and polyvinyl plastics bore adaptive and with vinyl tube stationary fit, two sections polyvinyl plastics tube outside mounting sleeves; The internal surface of sleeve pipe middle part is provided with annular protrusion; Annular protrusion internal diameter and flange outside diameter are adaptive, and annular protrusion is corresponding with the flange mounting point, and seal ring is installed at reducing place, annular protrusion both sides; Tighten ring is installed at the sleeve pipe two ends, and tighten ring closely contacts with seal ring.
Further, internal lining pipe outer wall middle part is provided with bulge loop, and bulge loop is corresponding with two sections vinyl tube joints.
Internal lining pipe plays support connecting piece, and sleeve pipe can play connection, seal action through being threaded with tighten ring, guarantees inner and outer sealing.
The utility model compare with traditional Placement have good sealing effect, long service life, simple in structure, make characteristics such as easy, easy for installation, quick; Be applicable to the unconventional job sites such as the end, lake (storehouse), seabed and mountain region of complicated topographical conditions.
Description of drawings
Fig. 1 is the structural relation schematic representation of the utility model.
Among the figure: 1-seal ring, 2-sleeve pipe, 201-annular protrusion, 3-tighten ring, 4-internal lining pipe, 401-bulge loop, 5-polyvinyl plastics, 501-flange.
Embodiment
Through accompanying drawing the utility model is done further detailed description below.As shown in the figure: a kind of small-bore polyvinyl plastics pipe connection comprises connected two sections vinyl tubes 5; Vinyl tube 5 ports are provided with flange 501, and flange 501 is in the process of two sections vinyl tubes 5 being carried out the connection heating, to form, and this connection set also comprises internal lining pipe 4, sleeve pipe 2, tighten ring 3 and seal ring 1; Internal lining pipe 4 is positioned at two sections vinyl tubes 5, internal lining pipe 4 external diameters and vinyl tube 5 internal diameters adaptive and with vinyl tube 5 stationary fits, two sections vinyl tube 5 outside mounting sleeves 2; Sleeve pipe 2 inwalls middle part is provided with annular protrusion 201; Annular protrusion 201 internal diameters and flange 501 external diameters are adaptive, and annular protrusion 201 is corresponding with flange 501 mounting points, and seal ring 1 is installed at reducing place, annular protrusion 201 both sides; The sleeve pipe 2 two ends tighten ring 3 that is threaded, tighten ring 3 closely contacts with seal ring 1.Through the threaded engagement extruding, make seal ring 1 reach better seal action.
Further, internal lining pipe 4 outer walls middle part is provided with bulge loop 401, and bulge loop 401 is corresponding with two sections vinyl tube 5 joints; Make the internal lining pipe supporting & stablizing firm.
The connecting end preheating of two sections vinyl tubes 5 that will connect earlier before the assembling; Then immediately two sections vinyl tubes are enclosed within on the stainless steel inner lining tube 4; After being set to stainless steel inner lining tube to vinyl tube, form flange 501 in the vinyl tube port; Insert again in the stainless steel sleeve pipe 2; Make the annular protrusion 201 of sleeve pipe 2 and flange 501 alignment of polyethylene pipe joint; Add seal ring 1 in the annular protrusion both sides then, be installed in the two ends of sleeve pipe 2 to tighten ring 3 through internal and external threads at last, reach the effect that connects sealing; Seal ring 1 reaches tube fluid (liquid/gas) and the extraneous effect of cutting off also through the physics squeezing action.
