Description
Technical field
The utility model relates to pipe fitting and connects field of sealing technology, particularly relates to a kind of heat-shrinkable T bush connected for pipe fitting.
Background technique
Material contracting with heat also known as polymer shape memory material, to be macromolecular material with radiation processing technology the intersect a kind of intelligent material combined.Common high molecular materials is as the normally linear structure such as polyethylene, PVC＝polyvinyl chloride, after the radiation effects of the radioactive sources such as electron accelerator becomes reticular structure, these materials will possess unique " memory effect ", and the material of expansion, cooling and shaping again can shrink and return to the original form after being heated.
Pipework heat-shrinkable product is the internal surface at radiant crosslinked polyethylene material contracting with heat, coating one deck High performance hot melt adhesive, during installation, material contracting with heat outside, because " memory effect " shrinks after being heated, internal layer hot melt adhesive is endothermic melting simultaneously, is tightly coated on outside pipeline.Because hot melt adhesive has good adhesive property, entering of external moisture can be stoped, thus play insulation, protection against the tide, the effect such as seal, protect and continue.
Heat-shrinkable T bush is being widely used in the connection of polyvinyl plastics waste pipe on the market.Existing heat-shrinkable T bush comprises plastic drain-pipe body and thermal shrinkable sleeve, thermal shrinkable sleeve is sleeved on body, the outer surface of body is provided with spiral helicine stiffening rib (stiffening rib had is PE material, and some stiffening ribs are that PE expects liner steel band), forms groove between stiffening rib and body.Helical is rectangular coil or ripple spiral.
Usual thermal shrinkable sleeve shrinks less than root of notch, and form gap, water can ooze out along gap spiral.Need to use plastic welding gun built-up welding, first a segment base of port recess is is originally filled and led up.But due to processing conditions restriction, built-up welding place is very lack of standardization, narrow and out-of-flatness, after installing, heat-shrinkable T bush often piles surperficial blow-by with weldering, can cause effluent seepage.Make the normal mechanical sealing adopting liner rubber plate and stainless steel anchor ear in existing engineering, owing to adopting the mechanical sealing of liner rubber plate and stainless steel anchor ear, make present technology there is high cost, the defect that sealing effect is also undesirable.
