Abstract
The utility model discloses a reduced tee fitting with a middle or large aperture used for PVC pipelines, which belongs to the drainage pipe material technical field and is used to solve the strength problem of tee fittings. The reduced tee fitting consists of a main pipe and a branch pipe, a branch pipe bell mouth which is convex toward the outside of the main pipe is arranged at the joint of the main pipe and the branch pipe, the inner diameter of the branch pipe bell mouth is matched with the outer diameter of the branch pipe, the branch pipe is inserted into the branch pipe bell mouth, and the branch pipe and the branch pipe bell mouth are connected by hot melt socket or bonding by adhesive. In the utility model, the convex branch pipe bell mouth is arranged outside the main pipe of the reduced tee fitting, the branch pipe is inserted into the branch pipe bell mouth, and the whole strength of the fitting is improved by arranging a coupling agent layer and an FRP reinforcing layer. The reduced tee fitting can improve the strength of the tee fittings, also has the advantages of simple processing technology, low production cost, and high production efficiency and so on, and can be widely used in fields such as water supply and sewerage, pollution discharge, chemical industry, wires, cables and so on.
Description
Technical field
The utility model relates to a kind of plumbing tubing special purpose parts, and the middle heavy caliber reducing tee pipe fitting especially for the pvc pipe road connects belongs to the tubing technical field.
Background technique
Along with the extensive use of PVC plastic pipe, use amount increases year by year, and the gesture of replacing various metallic conduits is gradually arranged greatly, and pipe joint all the more demonstrates its significance thereupon.In known technology, what existing tee pipe fitting mainly used is pipe fittings such as cast iron threeway, plastic three-way, stainless steel threeway.Though cast iron threeway intensity is high, corrosion resistance is relatively poor, corrosion easily, and production process is many, the cost height, application area is narrower; Stainless steel pipe cost height connects difficulty with plastic tube.The reducing tee pipe fitting that uses in the present thermoplastic pipeline product, the molding and forming of general employing injection machine, for small-bore pipe fitting, the molding and forming mode of production is comparatively economical, but for middle heavy caliber pipe fitting, just need to use large size plastic jetting-moulding device and injection mould, especially the reducing tee that uses of large diameter pipeline, injection mould processing is very complicated, has production cost height, process-cycle is long, and drawback such as involve great expense.Bore can't be processed substantially the above person of 400mm.In addition, general plastic three-way pipe fitting connects that plastic tube is easy, rotproofness is strong, but its intensity is lower.Tee pipe fitting is the stressed critical component of concentrating in the whole pipe, produces water hammer sometimes in the pipeline, and instantaneous pressure exceeds several times of normal values, therefore the plastic three-way fracture easily takes place in actual applications and cause weeping, directly influences the proper functioning of pipeline.
Summary of the invention
The utility model is used for overcoming the defective of prior art and provides a kind of low production cost, mechanical strength high and can save the heavy caliber reducing tee pipe fitting that is used for the pvc pipe road of material.
The alleged problem of the utility model is that following technological scheme solves:
A kind of heavy caliber reducing tee pipe fitting that is used for the pvc pipe road, constitute by the person in charge and arm, its specialization is: the described person in charge and arm joint are provided with to being responsible for an outside tube faucet that protrudes, described tube faucet internal diameter is complementary with an external diameter of pipe, and arm is plugged in the tube faucet, both are by thermofusible spigot or tackiness agent is bonding is integral.
The above-mentioned heavy caliber reducing tee pipe fitting that is used for the pvc pipe road, the described person in charge and arm joint outer surface are provided with coupling agent layer, are provided with the FRP reinforced layer outside coupling agent layer.
The above-mentioned heavy caliber reducing tee pipe fitting that is used for the pvc pipe road, the described person in charge and a tube faucet are an overall structure.
The utility model is low at large-bore plastics tee pipe fitting mechanical strength in existing, and the problem that cost of production is high is improved, be responsible for outer installment and be responsible for tube faucet one, that protrude to person in charge outside at the reducing tee pipe fitting, arm is arranged in the tube faucet, again the coupling agent layer by being arranged on persons in charge, arm joint and the bulk strength of FRP reinforced layer raising pipe fitting.The utility model has processing technology when improving heavy caliber reducing tee pipe fitting intensity simple, cheap, and cost of production is low, the manufacturing efficiency advantages of higher.Fields such as heavy caliber urban water supply and sewerage, blowdown, chemical industry, electric wire, cable in can being widely used in.
Description of drawings
Fig. 1 is the utility model structural representation.
Each parts label is expressed as follows among the figure: 1. be responsible for; 2. prop up tube faucet; 3. arm; 4.FRP reinforced layer; 5. coupling agent layer.
Embodiment
Referring to Fig. 1, the utility model by be responsible for 1 and arm 3 constitute, is responsible for differently with the arm diameter, be responsible for and the joint of arm is provided with to what be responsible for the outside protrusion and props up tube faucet 2, this tube faucet and the person in charge are an overall structure.Described tube faucet internal diameter is complementary with an external diameter of pipe, and arm is plugged in the tube faucet, and both are by thermofusible spigot or the bonding connection of tackiness agent.For improving the mechanical strength of pipe fitting, be provided with coupling agent layer 5 the person in charge and arm joint outer surface, outside coupling agent layer, be provided with FRP reinforced layer 4.
When making, the utility model intercepts the person in charge from corresponding specification tubing earlier, the position punching of arm is set on being responsible for, behind the heating and melting of perforation place cross section, utilize frock from being responsible for the inner outwards outstanding tube faucet of outside tube wall, pulling out through this hole, then arm bellmouth end face is cut flat the processing, again arm is plugged in the tube faucet, with prop up the tube faucet thermofusible spigot or tackiness agent is bonding is connected, being responsible for and arm joint outer surface coated with coupling agent layer 5, outside coupling agent layer, be provided with FRP reinforced layer 4 at last.
Claims (4)
