Description
Technical field
The utility model tee pipe fitting, specifically refers to a kind of Three way type metal framework plastic composite pipe fitting.
Background technique
Metal framework plastic composite pipe, a kind of tubing that recent year is emerging, its structure is that internal and external layer is plastics, mesosphere is metal frame (as steel mesh framework etc.), adopt special bonding resin that metal frame is mutually compound with internal and external layer plastics, because of its special structure, the advantages such as tubing has that bearing capacity is strong, good corrosion resistance, wear-resisting property are good, being widely used in the fields such as urban construction, petrochemical industry, power communication, metallurgical mine and agricultural irrigation, is the best substitute products of the conventional pipelines such as steel pipe, cast iron tube and cement pipe.
Existing metal framework plastic composite pipe, when pipeline construction, often needs to connect upper tee pipe fitting, realizes the threeway of pipeline.In prior art, the tee pipe fitting connecting for the threeway of metal framework plastic composite pipe generally is the tee pipe fitting of pure plastic materials.The intensity of this tee pipe fitting is low, and bearing capacity is poor, is difficult to meet piping layout needs.In addition, also have a kind of composite three-way pipe fitting with metal frame in prior art, this composite three-way pipe fitting is by being arranged on the metal frame of three-way pipe shape, by injection moulding mode at metal frame outer cladding plastic layer.This mode machining needs shot capacity large, and equipment cost is high.
Summary of the invention
The purpose of this utility model is the shortcoming and defect existing in order to overcome prior art, and provide, a kind of structural strength is strong, bearing capacity good, and the low Three way type metal frame composite pipe fitting of production and processing cost.
For achieving the above object, the technical solution of the utility model is to comprise the compound supervisor of metal framework plastic, on the described compound supervisor's of metal framework plastic sidewall, be provided with attachment hole, on described attachment hole, sealing is fixedly installed side pipe, the lower end of described side pipe extend in attachment hole and outwards and laterally bends and be provided with annular urosome, this annular urosome is sealingly fastened on the inwall of the relative attachment hole periphery of the compound supervisor of metal framework plastic, the sidepiece of described side pipe is fixedly installed outer retaining ring, the lower end surface of this outer retaining ring is sealedly and fixedly connected with the outer wall of the relative attachment hole periphery of the compound supervisor of metal framework plastic.By this setting, the compound supervisor of the metal framework plastic of take is basal body pipe, then connects side pipe in attachment hole thereon, and not only processing and assembling is convenient, and cost is low, and has utilized the compound supervisor's of metal framework plastic the strong advantage of bearing capacity itself.
Further arranging is that described side pipe is plastic tube.This setting, can directly adopt injection moulding mode, by side pipe injection moulding by mold injection on supervisor, shot capacity is little, cost is low, quality of processing is stable.
Further arrange is that described side pipe includes side pipe metal frame and the coated plastic layer that is arranged at side pipe metal frame outside.By this setting, described side pipe also adopts the structure of metal framework plastic composite pipe, and this structure has metal framework plastic composite pipe itself and has outside the advantages such as bearing capacity is strong, or this side pipe is when injection molding, reduce shot capacity, and then reduced injection molding cost.
Further arranging is that described side pipe metal frame is punching steel mesh pipe, and the lower end of this punching steel mesh pipe is provided with the annular punching steel mesh body being placed in annular urosome.By this setting, punching steel mesh pipe itself just has stronger structural strength, when the plastic layer injection moulding of side pipe, keeps the accuracy of its position, has improved injection moulding quality.
Further arranging is that the described inner side surface of outer retaining ring and the plastic layer compound seal in the outside of side pipe are fixed, and the downside of described outer retaining ring and the compound supervisor's of metal framework plastic outer wall compound seal is fixed.By this setting, outer retaining ring and side pipe are the structure of two splits, can carry out at twice injection moulding, and then assemble compound fixing, and the compound fixing mode of its assembling preferably adopts hot melt composite joint.
Further arrange is described outer retaining ring and the plastic layer integrated injection molding in side pipe outside.This designs simplification the assembling of outer retaining ring and side pipe, improved work efficiency.
Further arranging is that described outer retaining ring is that half section is leg-of-mutton rotation body structure.This support structure is effective.
In sum, the utility model has the advantages that: structure arranges rationally, and processing cost is low, and have that bearing capacity is strong, the advantage such as good corrosion resistance, wear-resisting property are good.
Below in conjunction with specification drawings and specific embodiments, the utility model is described further.
