Abstract
The utility model provides a connection structure for connecting plastic drain pipes with outer walls having spiral reinforcing ribs. The connection structure comprises water stoppers and a thermoplastic plastic connecting layer, wherein at least one water stopper is arranged at each spiral channel inlet formed by the reinforcing ribs in a connection area of a pipe end, the water stoppers are made of materials the same with the plastic materials of the pipes, are connected with lateral sides of the reinforcing ribs and the outer walls of the pipes by means of fusion welding, and are thick enough so as to guarantee that enough contact welding surfaces are reserved for the top ends thereof and the plastic connecting layers, and curve surfaces at the top ends of the water stoppers are flat and located on a coaxial cylindrical surface together with the top ends of the reinforcing ribs. Further, the thermoplastic plastic connecting layer which is made of the same materials with the plastic materials of the pipes covers the curve surfaces at the top ends of the reinforcing ribs and the curve surfaces at the top ends of the water stoppers, and is in a corrugated natural-shrinking state. In addition, the surface of the plastic connecting layer is coated with an electric melting tape.
Description
Technical field
The utility model relates to a kind of syndeton that outer wall has the plastic drain pipe of spiral ribs that is used to connect.
Background technology
The groundwork load of plastic draining pipeline is the pressure of outside soil and surface car etc., therefore requires it that enough ring stiffness are arranged.In order to save the ring stiffness that cost of production effectively improves product, most of plastic drain-pipes have all adopted the structure wall construction, wherein a kind of is the spiral ribs that uniform pitch is arranged on outer pipe wall, the steel band that also is compounded with in ribs that has is strengthened, and ZL200520112528.4 has just stipulated this product (see figure 1).Adopting Electric thermal smelting belt to connect the plastic pipe with solderability, have advantages such as good seal, anti-corrosive properties are good, pipe-line system life-span unanimity, is a kind of comparatively desirable plastic draining pipe connecting method that generally adopts.But above-mentioned outer wall has the plastic drain pipe of rib-like structure, directly adopt Electric thermal smelting belt to connect the following problem that exists: the plastics of moulding compound ribs top owing to steel are thinner, very easily cause heating wire to contact when adopting Electric thermal smelting belt to connect and form short circuit with steel band, in addition, because the uneven employing Electric thermal smelting belt of outer wall is connected in the operation also extremely difficult.For addressing the above problem, the applicant once adopted following handling a case: at the formed spiral channel inlet of ribs water bloking piece is set 1., space between the ribs is filled and led up with packing material, form one and comprise the coaxial of fin top curved surface, water bloking piece top end face, packing material outer round surface with the diameter circle cylinder, at this surface, face of cylinder parcel one deck thermoplastic material articulamentum, thereby form a smooth articulamentum that does not produce ripple, afterwards the hot melt band is coated on thermoplastic material articulamentum surface, implements to connect the electric heating of tubing is molten; 2. at the formed spiral channel inlet of ribs water bloking piece is set, form one and comprise the coaxial of fin top curved surface, water bloking piece top end face with the diameter circle cylinder, at this surface, face of cylinder parcel one deck shrink belt articulamentum, the hot melt band is coated on shrink belt articulamentum surface, enforcement connects the electric heating of tubing is molten, be heated to shrink to pack tightly by shrink belt this moment and eliminate issuable ripple form, realization is tightly connected with Electric thermal smelting belt.Yet show such scheme 1 through practical application: the process that the space between the ribs is filled and led up with packing material is cumbersome, has increased the complexity and the cost of production of process; Scheme 2: because Electric thermal smelting belt is the polythene material with polarity, it is not firm with combining of the shrink belt that contains glue-line, after after a while, breaks away from.
The utility model content
The purpose of this utility model provide a kind of can overcome above-mentioned defective connect the syndeton that external surface has the plastic pipe of spiral ribs from the outside with Electric thermal smelting belt.
For achieving the above object, the utility model provides is used to connect the union of thermoplastic plastic pipe that external surface has the spiral ribs of protrusion, at least one water bloking piece that comprise 1, formed each the spiral channel inlet of ribs is provided with in the pipe end join domain, 2, in the pipe end join domain, coat one deck thermoplastic articulamentum of being corrugated natural contraction state identical of ribs top curved surface and water bloking piece top curved surface, 3, at the surface coated Electric thermal smelting belt of this plastics articulamentum with the tubing plastic material.The technical scheme that the utility model adopted is: the plastic drain-pipe that has the spiral ribs for outer wall, in its end join domain according to a number of spiral ribs, formed all conduit entrance between ribs are provided with at least one water bloking piece, prevent that medium crossheading road from flowing.This water bloking piece must have adequate thickness to guarantee its top certain area to be arranged, its material must be identical with the tubing plastics, must melting welding link to each other with reinforcing rib sides and outer pipe wall, guaranteeing fixation and sealing, its top curved surface answer smooth and with the ribs top on a coaxial circles cylinder.Then ribs top curved surface and water bloking piece top curved surface coat again a layer thickness evenly, satisfy electric heating melting welding requirement and the thermoplastic articulamentum identical with the tubing plastics.This thermoplastic articulamentum must combine with ribs and water bloking piece top curved surface in melting welding, and is corrugated nature contraction state after the cooling.At last, adopt conventional Electric thermal smelting belt that this articulamentum is carried out the electric heating fusion welding.In this technical scheme, Electric thermal smelting belt is connected with the melting welding of union outer layer plastic articulamentum and the melting welding of this thermoplastic plastic layer and ribs and water bloking piece end face has been connected to form the complete sealing of tubing pumped (conveying) medium.This technical scheme is compared with former scheme 1, removed the packing material that the space is used between the ribs, this makes plastics articulamentum surface be corrugated nature contraction state, but by facts have proved of inventor, because the mobile compensating action of molten thermoplastic plastics in the electric heating fusion process, make the gap that may exist between itself and the Electric thermal smelting belt that is that the ripple state causes owing to thermoplastic articulamentum surface be compensated filling, electric heating melting welding finish and cool off after can make fully between thermoplastic articulamentum and the Electric thermal smelting belt and to form even gapless welding, thereby guarantee the excellent sealing of the utility model tubing connector.
The utility model is compared with former scheme 1, owing to removed the packing material that the space is used between the ribs, process is become simply, and reduced cost of production; Compare with former scheme 2, owing to no longer adopt shrink belt, thus the situation of having avoided breaking away from Electric thermal smelting belt takes place.
