Abstract
The present invention relates to a special plastic composite pipe with a reliable connection property and a reliable sealing property, which comprises the special plastic composite pipe and a connecting method thereof. The present invention is characterized in that the composite pipe is composed of two layers, wherein the inner layer is a wear-resistant and corrosion-resistant layer made of PPR plastics or polyethylene plastics, and the outer layer is a corrosion-resistant and pressure-resistant layer made of polyethylene plastics or polyvinyl chloride plastics which is mixed with a steel net; both of end parts of the inner layer of the special plastic composite pipe are turned outwards for an angle of 30 degrees or 60 degrees; the outer layer is gradually thickened in the deformation zone of the inner layer and forms an included angle of 120 degrees or 150 degrees with the inner layer, and the outer layer is in the shape of a Chinese character 'tu' (convex); a 'tu'-shaped ferrule which is matched with the 'tu'-shaped surface, namely a clamping head, is designed on the surface, and the clamping head is connected by a clamp; an annular sealing ring of which the cross section is an isosceles triangle with an angle of 30 DEG or 60 DEG is designed in a space formed by two opposite pipe heads, and the clamp is connected by a bolt and a nut.
Description
One, technical field: the invention discloses the special plastic composite of a kind of connection reliable sealing.
Two, background technique: PVC, polyethylene, PVC steel netting pipe, the steel plate webmaster of domestic production at present, pressure is applicable to more than the 2Mpa, can be adapted to the pressure requirement as pipe itself, accomplishes not to be seeped into and leaks.But leakage problem takes place in pipe and pipe joint often.Even do not leak during pressure testing, but because the variation of variation of temperature or pressure in pipe gas transmission or the infusion process causes the vibrations and the distortion of pipeline, the joint will produce and leak or seepage this moment.Special plastic composite is promoted not opened, and except that the high factor of price, main is that joint connection sealing does not pass a test.
Three, summary of the invention: purpose of the present invention is exactly the above-mentioned defective that exists at prior art, provides a kind of connection reliable sealing special plastic composite.
Technological scheme of the present invention is achieved through the following technical solutions:
The present invention includes plastic composite and Placement.This special plastic composite is made up of two-layer, its internal layer is that PPR plastics or polyvinyl plastics are made the wear-and corrosion-resistant layer, it is outer makes anti-corrosion Withstand voltage layer for polyethylene or igelite and steel netting, it is characterized in that internal layer with the two end part of special plastic composite is to 30 ° or the 60 ° of angles of turning up, skin is thickeied gradually in the texturing zone of internal layer, form 120 ° or 150 ° of angles with internal layer, be convex shape, at one of convex shape top layer design convex shape cutting ferrule that matches with it is clip, the clip head is by clip connected, at the loop type seal ring that cross section of spatial design that two tube heads form relatively is 30 ° or 60 ° isosceles triangles, clip is connected by bolt and nut.Cutting ferrule is symmetrical two lobe formulas, is provided with protruding tongue or groove separately at the rear portion of cutting ferrule two lobes; Be provided with steel ring in ring type seal ring inside.
The present invention has compared following advantage with existing special plastic composite:
1, the good of envelope sealed at the interface tube place, and bulge explosion string hole is scurried into, caused to liquid that can not along steel wire head.
2, pipe connection sealing means is good, and it is reliable that sealing is reliable withstand voltage.
Four, description of drawings:
Fig. 1-structural representation of the present invention;
Five, embodiment:
Be described in detail by embodiment below in conjunction with Figure of description for further disclosing technological scheme of the present invention:
The present invention includes special plastic composite and Placement, it is characterized in that special plastic composite is made up of two-layer, its internal layer 4 is made the wear-and corrosion-resistant layer for PPR plastics or polyvinyl plastics, it outer 3 makes anti-corrosion Withstand voltage layer for polyethylene or igelite and steel netting, with the internal layer at the two end part of special plastic composite to 30 ° or the 60 ° of angles of turning up, its skin is thickeied gradually in the texturing zone of internal layer, form 120 ° or 150 ° of angles with internal layer, be convex shape, at one of convex shape top layer design convex shape cutting ferrule that matches with it is clip 2, the clip head is connected by clip 1, the loop type seal ring 6 that is 30 ° or 60 ° isosceles triangles in cross section of spatial design that two ends forms relatively, establish steel loop 5 in the seal ring, clip is connected by bolt 7 nuts 8.The clip head makes protruding tongue relative with recess relatively, and isosceles triangle ring type seal ring is clipped in the centre of two tube heads, and the card front band gets final product.
Claims (3)
1, the special plastic composite of a kind of connection reliable sealing, the Placement of special plastic composite specifically, this composite pipe is made up of two-layer, its internal layer is that PPR plastics or polyvinyl plastics are made the wear-and corrosion-resistant layer, it is outer makes anti-corrosion Withstand voltage layer for polyethylene or igelite and steel netting, it is characterized in that internal layer at the two end part of special plastic composite is to 30 ° or the 60 ° of angles of turning up, skin is thickeied gradually in the texturing zone of internal layer, form 120 ° or 150 ° of angles with internal layer, be convex shape, at one of convex shape top layer design convex shape cutting ferrule that matches with it is the clip head, the clip head is by clip connected, at the loop type seal ring that cross section of spatial design that two tube heads form relatively is 30 ° or 60 ° isosceles triangles, clip is connected by bolt and nut.
2, the special plastic composite of connection reliable sealing according to claim 1 is characterized in that cutting ferrule is symmetrical two lobe formulas, is provided with protruding tongue or groove separately at the rear portion of cutting ferrule two lobes.
3, the special plastic composite of connection reliable sealing according to claim 1 is characterized in that being provided with steel ring in ring type seal ring inside.
