Description
Technical field
Conversion pipe fitting moulded by the steel that the utility model belongs to a kind of fuel gas transportation pipeline in fuel gas transportation pipeline component technology field.
Background technique
Along with the growing of fuel gas transportation pipeline and scientific and technological progress, correspondingly conversion pipe fitting technical requirements moulded to the steel of fuel gas transportation pipeline also more and more higher.In known technology, what the steel of existing fuel gas transportation pipeline moulded that conversion pipe fitting mainly adopts is made up of PE pipe end, support ring, O type cushion rubber, steel pipe end.Steel pipe end is welded by bellmouth and tail pipe.PE pipe end is inserted in the bellmouth position of steel pipe end during assembling, then support ring is pressed into connection part in PE pipe end, be connected with extruding PE pipe end inside and outside bellmouth by support ring.But limit by its structure, its linkage structure is complicated, the subject matter existed is, PE pipe end produces wall thickness because being squeezed in connecting part thinning, cause steel to mould the axial pulling capacity of conversion pipe fitting to decline, cause when using under the severe environmental conditions such as earthquake, landslide, its tensility and sealability cannot ensure, especially when there is potential safety hazard for during steel gas pipe underground system; Inside pipe fitting causes again pipe fitting local latus rectum to diminish because of the existence of support ring, causes pipe fitting to produce larger Pressure Drop in test with actual motion, especially moulds the use impact of conversion pipe fitting to DN63mm and following steel larger; Steel pipe end welding fabrication process produces arc light, flue gas easily produces pollution to working environment, brings inconvenience also to actual use.
Model utility content
In order to overcome the deficiencies in the prior art, it is complicated that conversion pipe fitting joint structure moulded by the steel solving existing fuel gas transportation pipeline, there is potential safety hazard, easily produces the problem polluted.It is simple and practical that the object of the utility model is to provide a kind of linkage structure, effectively can avoid potential safety hazard, free from environmental pollution, when using under the severe environmental conditions such as earthquake, landslide exactly, its tensility and sealability also can ensure, mould conversion pipe fitting to DN63mm and following steel and also do not affect application, conversion pipe fitting moulded by new-type fuel gas transportation pipeline steel easy to use.
The technical scheme in the invention for solving the above technical problem is:
Conversion pipe fitting moulded by a kind of fuel gas transportation pipeline steel, it is provided with: joint for plastic tube, steel pipe joint, telescopic Steel Skeleton, joint for plastic tube is the joint for plastic tube that interface agent inner tube wall is shaped with that annular groove becomes semiclosed G shape interface with the cross section of conjuncted inner sleeve, steel pipe joint is that connector portions outer wall is shaped with undergauge step, undergauge step front portion is shaped with annular groove, and the collar extension limit of annular groove is the steel pipe joint on annular circular arc boss seam edge, telescopic Steel Skeleton sleeve body wall is shaped with several radial direction through hole and sleeve lining is shaped with interior stop ring connected in star, and the collar extension limit of interior stop ring connected in star is the telescopic Steel Skeleton of sleeve convex eave tile opening's edge, between joint for plastic tube and steel pipe joint i.e. joint for plastic tube annular groove in and steel pipe joint undergauge step on be embedded with telescopic Steel Skeleton, the radial direction through hole worn between the conjuncted inner sleeve of joint for plastic tube and its outer body pipe on connected set cartridge type Steel Skeleton sleeve body wall is shaped with conjuncted post.
Conversion pipe fitting moulded by above-mentioned fuel gas transportation pipeline steel, and the pipe joint body of described joint for plastic tube is that arc-shaped transition is conjuncted with the junctor that is connected between interface section.
Conversion pipe fitting moulded by above-mentioned fuel gas transportation pipeline steel, on the connector portions outer wall undergauge step of described steel pipe joint the telescopic Steel Skeleton of setting-in be taperedly to be threaded, be threaded add some points solderedly to connect, interference press-fits connection, any one linkage structure of being welded as a whole.
Conversion pipe fitting moulded by above-mentioned fuel gas transportation pipeline steel, and the outer surface of described telescopic Steel Skeleton is shaped with hatching knurling.
Conversion pipe fitting moulded by above-mentioned fuel gas transportation pipeline steel, described joint for plastic tube be faucet type joint for plastic tube, mouthing joint for plastic tube, bending head type joint for plastic tube, electric smelting mouthing straight tube joint for plastic tube, electric smelting mouthing bend pipe joint for plastic tube any one, and other adaptive type joint for plastic tube.
Conversion pipe fitting moulded by above-mentioned fuel gas transportation pipeline steel, described steel pipe joint be straight tube, bend pipe, branched pipe, reducer pipe be shaped with internal thread, any one steel pipe joint externally threaded with interface.
Conversion pipe fitting moulded by steel of the present utility model is adopt single injection-molded; During use, according to designing requirement, direct load is to fuel gas transportation pipeline.
Because the utility model design have employed technique scheme, conversion pipe fitting moulded by this steel is the material differed greatly by metal and plastics two kinds of physical and chemical performances, the mutual intersection adopted is hooked together formed linkage structure, no matter cold, heat, swollen, contracting, stretch, reverse and wait the steel that even can closely join together under severe environmental conditions to mould conversion pipe fitting, its major technique key point had both ensured its compressive strength, there is again reliable sealing simultaneously, it is complicated that conversion pipe fitting joint structure moulded by the steel efficiently solving existing fuel gas transportation pipeline, there is potential safety hazard, the easy problem producing pollution.Also show through testing result on trial for several times, it compared with prior art, there is linkage structure simple and practical, effectively can avoid potential safety hazard, free from environmental pollution, when using under the severe environmental conditions such as earthquake, landslide exactly, its tensility and sealability also can ensure, mould conversion pipe fitting to DN63mm and following steel and also do not affect application, the advantage such as easy to use, is applicable to fuel gas transportation pipeline.
