Abstract
The utility model provides an extrusion metal-plastic multiple tube fitting, comprising a metal casing (1) with a bell (A) and a sealing groove (5), and a sealing connection elastic sealing ring (4) installed in the sealing groove (5). The utility model is characterized in that the void non-bell portion of the metal casing (1) is further provided with a plastic inner covering (2), the end-face of the plastic inner covering (2) is provided with an end-face elastic sealing ring (3). The plastic inner covering (2) and the end-face elastic sealing ring (3) are used to obstruct the transported medium from contacting with the metal casing and the metal-plastic multiple tube, and the deforming of the bell pressing portion (B) of a casing 1 and the sealing connection elastic sealing ring (4) is used to achieve the leak-free firm connection of the metal-plastic multiple tube fitting and the metal-plastic multiple tube fitting. Realizing keeping the pureness of the transported medium, the utility model has the advantages of little resistance in transport, wear resistance, corrosion prevention, thermal insulation, perfect sealing property, high construction efficiency, energy conservation, reducing consumption and the like. The utility model is applied to water supply and sewerage, chemical industry, petroleum, mineral extraction, food, medicine and the like metal-plastic multiple tube conduit project.
Description
One, technical field
The utility model belongs to a kind of extruding type composite tube of metal and plastic.Be applicable to the application on the composite metal-plastic pipes engineerings such as plumbing, chemical industry, oil, mining, food, medicine.
Two, background technique
At present, used the extruding type stainless steel pipe of JWWAG166 " water channel stainless steel pipe " the specification standards manufacturing of formulating in the composite metal-plastic pipes engineering, replaced traditional thread type pipe fitting by Japanese water channel association.This extruding type pipe fitting has advantages such as easy construction, work efficiency height, good airproof performance than thread type pipe fitting.But the shortcoming that this class extruding type metal pipe element exists a maximum is the medium of being carried can directly be contacted with metal, and influence is transferred the purity of medium.And the metallic walls friction ractor is big, and is easy to wear, can reduce the conveying capacity and the working life of pipeline.So this metal pipe element can't satisfy the strong medium of high-purity medium, corrosivity and the conveying of solidliquid mixture, does not also meet energy-saving and cost-reducing requirement.
Three, summary of the invention
The utility model provides and a kind ofly can keep that fed sheet of a media purity, transporting resistance are little, wear-resistant, the extruding type composite tube of metal and plastic of insulation.
Extruding type composite tube of metal and plastic of the present utility model, the metal shell that comprises band bellmouth and seal groove be contained in seal groove in be connected elastic seal ring, it is characterized in that it comprises that also the described plastic inner lining layer of plastic inner lining layer is positioned at the non-bellmouth of metal shell inner chamber position, and fit tightly with metal shell.
Better for the end face seal degree of the plastic inner lining layer that makes composite tube of metal and plastic and composite metal-plastic pipe, can add the upper-end surface elastic seal ring at plastic inner lining layer end face.This end face elastic seal ring and plastic inner lining layer end face and metal shell inwall closely cooperate.
For making plastic inner lining layer and metal shell inner chamber bonding fastening, available adhesive layer adhering junction between plastic inner lining layer and the metal shell.
For guaranteeing the sanitation performance of fed sheet of a media, the available plastic inner lining layer that is added with antimicrobial agent of plastic inner lining layer.
Metal shell can be made with stainless steel, copper, aluminium or carbon steel material, and wall thickness is 0.8-1.5mm.The available PE of plastic inner lining layer, PP or PB plastic materials are made, and wall thickness is 0.5-2mm.
When using the utility model, only need composite metal-plastic pipe is injected in the bellmouth of extruding type composite tube of metal and plastic, and firmly extruding makes the end of composite metal-plastic pipe press the end face elastic seal ring, make not have to leak between the plastic inner lining layer of composite metal-plastic pipe and extruding type composite tube of metal and plastic and be connected, with the extruding position of compression tool extruding bellmouth, make the distortion of bellmouth position again.At this moment, the composite tube of metal and plastic bellmouth be extruded outward position and this place composite metal-plastic pipe be squeezed into hexagon, the diameter of seal groove is compressed and diminishes, both just can not have to leak firmly and connect.
Extruding type composite tube of metal and plastic of the present utility model is the medium that utilizes plastic inner lining layer and end face elastic seal ring to intercept to be transferred and the metal layer contacting of metal shell and composite metal-plastic pipe, and the distortion that utilizes the housing bellmouth extruding position of extruding type composite tube of metal and plastic and the elastic seal ring that is tightly connected reaches composite tube of metal and plastic and does not have leakage with the composite metal-plastic pipe material and firmly be connected, realized keeping being transferred the purity of medium, and it is little to have a transporting resistance, wear-resistant, corrosion-resistant, insulation, good airproof performance, easy construction, advantage such as energy-saving and cost-reducing.Be applicable on the composite metal-plastic pipes engineerings such as plumbing, chemical industry, oil, mining, food, medicine and use.
Four, description of drawings
Accompanying drawing 1 is the schematic representation of the utility model extrusion metal plastic composite pipe.
1 is metal shell among the figure, the 2nd, and the plastic inner lining layer, the 3rd, the end face elastic seal ring, the 4th, the elastic seal ring that is tightly connected, the 5th, seal groove, A are bellmouths, B is bellmouth extruding position.
Five, specific embodiments
Referring to accompanying drawing 1, making wall thickness with stainless steel material through machining and welding method is the band bellmouth A of 1mm and the metal shell 1 of seal groove 5, with the plastic inner lining layer 2 of injection molding technique at metal shell 1 non-bellmouth position lining wall thickness 1.2mm, the plane end face elastic seal ring 3 of making thick 2mm with silicone rubber is installed on the end face of plastic inner lining layer 2, again the O type made from the silicone rubber elastic seal ring 4 that is tightly connected is installed in the seal groove 5 of metal shell 1 bellmouth A end, can make extruding type composite tube of metal and plastic of the present utility model.
