Abstract
The utility model provides a quick-mounting pipe joint which is composed of a pipe and end heads. The pipe is sheathed on the jointing parts of two steel pipes which are needed to be connected together. Both the end heads are clamped at both ends of the pipe. The external circles of both ends of the pipe are cone-shaped. Embedded with sealing rings made of nylon plastics or rubber, the internal circles of both ends of the pipe are also cone-shaped, and corrugated grooves are arranged on the surface of the cone. The quick-mounting pipe joint has the advantages of simple structure, easy production, flexible disassembly, convenient operation, etc., and can be widely used in fast assembling construction of water pipes, gas pipes and heating pipes of industrial facilities, agricultural facilities, mining facilities and civil facilities.
Description
The utility model relates to a kind of assembling pipe joint, specifically a kind of fast holding pipe joint.
The conveying of various liquid, gas be unable to do without pipeline, and as pipeline, gas pipe, heating pipe or the like from the beginning, pipeline has the branch of stereoplasm tube and soft pipe again, and stereoplasm tube has various metal tubes, plastic conduit, and flexible pipe then is various plastic flexible pipes.No matter be stereoplasm tube or soft pipe, being connected of pipeline and pipeline in use all unavoidably arranged, the connection ratio between the flexible pipe is easier to, and two sections flexible pipes can be coupled together with one section hard tube.The connection of hard tube is then more bothersome, the mode that connects stereoplasm tube with prior art is mainly welded two kinds with threaded pipe joint connection or with electrogas welding, the stereoplasm tube of medium and small straight warp generally is to connect with threaded pipe joint, the steel pipe of big straight warp or the connection of the copper pipe of ultra-fine diameter generally are to connect with the mode of welding, and then are to connect with electric welding or gas welding as bigbore gas pipe line, small-bore refrigerator radiator pipeline.But in daily life and industrial production, use maximum stereoplasm tubes to be mostly steel pipe, when connecting the steel pipe of medium and small straight warp with screwed pipe joint, at first be on connected steel pipe tube head, to put silk, just can be screwed on the pipe joint then, though the pipe joint that the connection steel pipe is used all is a standard piece, just available in the shop, but on the steel pipe tube head, mantle fiber not a nothing the matter just, instruments such as pipe tong and pipe thread chaser must be arranged, pipeline spread is the most time-consuming in pipeline construction, is exactly the mantle fiber of pipeline.Again by washing machine manufacturing enterprise, employed many criteria of right and wrongs of pipeline part in the washing machine, so the connection of pipeline will be used the dedicated pipe joint, these threaded pipelines and pipe joint use on mounting production line, not only increased cost of production, and time-consuming, manufacturing efficiency is low, incompatibility production line operation fast.The fast holding pipe joint that does not also have at present pipeline just can couple together pipeline and pipeline without mantle fiber.
The purpose of this utility model provides on a kind of steel pipe tube head the fast holding pipe joint that just can couple together steel pipe without mantle fiber.
The purpose of this utility model is by realizing with the lower direction formula, screw thread is gone up in the processing of the cylindrical of one tube coupling end, the end of tube coupling adds a rubber-plastic sealing ring and a taper bail wire, with the end not the pipeline of mantle fiber inject the tube coupling from the end of tube coupling, then threaded nut with cone-shaped inner hole is screwed in the end of tube coupling, with taper bail wire and rubber-plastic sealing ring and not the pipeline of mantle fiber be fixed on the end of tube coupling in the lump.During installation, the taper bail wire in the fast-assembling tube coupling head clamps distortion with the rubber-plastic sealing ring under the compressing of nut taper hole, make tube coupling and sealing for tubing joints.
Figure of description is the linkage structure schematic representation between fast holding pipe joint and the pipeline.
Explain below with reference to Figure of description fast mounting pipe joint of the present utility model being done.
Fast mounting pipe joint of the present utility model, its structure be by nut 4, tube coupling 1, pipeline 6, Taper bail wire 3, anti-rotation pad 7, rubber-plastic sealing ring 2 consist of, and the end of pipeline 6 is inserted in pipe Among the joint 1, nut 4 is with pipeline 6, taper bail wire 3, anti-rotation pad 7 and rubber-plastic sealing ring 2 are fixed on the end of tube coupling 1.
Be processed with screw thread on the end cylindrical of tube coupling 1, half is processed with screw thread the interior circle of nut 4, half is processed into taper, the cylindrical of taper bail wire 3 is processed into taper, taper in its tapering and the nut 4 in the circle matches, also be processed with circumferential wave groove 5 on the interior circle of taper bail wire 3, circumferential wave groove 5 is stuck on the cylindrical of pipeline 6.
Embodiment:
The processing and fabricating of fast holding pipe joint of the present utility model is very simple and convenient, process screw thread on the end cylindrical with tube coupling shown in the by specification accompanying drawing, screw thread is gone up in half processing in the interior circle of nut, half is processed into taper, the outer fenestra of taper bail wire is processed into taper, want consistent with the angle of taper in the nut, and in the taper bail wire, process the circumferential wave groove on the circle.When installing and using, taper bail wire, anti-rotation pad, rubber-plastic sealing ring can be placed to successively and be screwed to the tube coupling two ends in the nut, and then the pipeline that will connect fast holding pipe joint two ends injects in the tube coupling from the center hole of nut, at last nut and tube coupling are tightened, with this two pipelines are coupled together, the rubber or the plastic seal ring that are clipped in taper snap ring and tube coupling end are subjected to squeeze distortion with fast holding pipe joint and seal for pipe joints.The effect of anti-rotation pad is when preventing upper cap nut because the taper bail wire is lost its sealing with the rotation meeting of nut with the rubber seal damage.Tube coupling described in the above-mentioned article comprise straight-through tube coupling, threeway tube coupling, four-way tube coupling and elbow, reducing tube coupling, and other play all kinds of pipe connectors of interconnect function.Pipeline is meant the various stereoplasm tubes that are used to carry liquid, gas.
Fast holding pipe joint of the present utility model generally only is used for the quick connection of civilian electromechanical equipment or hot-water heating facility, do not have family's hot-water heating installation of steel pipe machining tool, can be used for the ventilating drainage operation of the frequent farmland discharging-irrigating of piping erection dismounting, building site, mine etc. yet.
Fast mounting pipe joint of the present utility model be compared with existing technology have simple in structure, be easy to processing, Dismantle flexible, easy to use, etc. characteristics, can be widely used in industry, agricultural, mine, civilian establishing The Fast Installation construction in the water of executing, gas, heating coil road, thereby, have good value for applications.
