Abstract
The utility model relates to a joining device for thin-wall stainless steel pipes, which is simultaneously suitable for the join between other nonmetal pipes or composite pipes. The utility model is characterized in that the joining device is composed of an outer sleeve pipe, a sealed ring and a spiral pipe plug, wherein, the outer sleeve pipe is connected and matched with the spiral pipe plug through threads; the sealed ring is arranged at the end surface side of the spiral pipe plug or the inner side of the outer sleeve pipe or on the outer surface of a thin-wall pipe; the inner end of the outer sleeve pipe is crossed with the end surface of the thin-wall pipe. When the thin-wall pipe is sheathed in the outer sleeve pipe, the spiral pipe plug is screwed tightly; the sealed ring is extruded to generate radial deformation; thus, the thin-wall pipe and the joining device are firmly joined and sealed. The joining method has the advantages of convenient installation, firm structure and favorable sealing performance. The reality that the thin-wall stainless steel pipes are used as water pipes becomes true. The utility model can also be used for joining other liquid and gas pipelines.
Description
The utility model relates to a kind of thin-wall stainless steel pipe connection, is applicable to the connection between other nonmetallic pipe or the composite pipe simultaneously.
Replace galvanizing pipe with thin-wall stainless steel, have advantages such as corrosion-resistant and beautiful shape, but because tube wall is very thin, can not resemble and cut with scissors spiral shell the galvanized pipe and connect.Also not having other to link firmly again at present can leakproof and simple in structure, by adorning Placement easily, to such an extent as to thin-wall stainless steel can't be used for water supply pipe.
The purpose of this utility model is will overcome the deficiency that prior art exists and design a kind of connection set, and thin walled tube is coupled together, and is applied to water supply pipe, and the thin walled tube connection set of other transfusion, gas pipeline.
These connection set characteristics are to be made up of outer sleeve, seal ring and screwed pipe plug, and outer sleeve is threaded with the screwed pipe plug and cooperates, and seal ring places on the inboard thin walled tube outer surface of screwed pipe plug end face outer sleeve, and outer sleeve is inner to intersect with the thin walled tube end face.
When thin walled tube packs into outer sleeve, screw the screwed pipe plug, extrude seal ring and make seal ring produce radial deformation, thin walled tube and connection set are linked up and make it sealing securely.This connecting means, easy for installation, sound construction, favorable sealing property makes thin-wall stainless steel etc. use as water pipe and becomes a reality, and also can be used as other liquid steam pipe road and connects and use.
Further illustrate the utility model below in conjunction with description of drawings, provide embodiment simultaneously.
Fig. 1 is the utility model embodiment's a structure sectional view.
Wherein: 1, outer sleeve; 2, seal ring; 3, screwed pipe plug; 4, inner sleeve; 5, thin walled tube; 6, interior projection.
As shown in the figure, the connection set of present embodiment is by outer sleeve 1, screwed pipe plug 3, seal ring 2 is formed, seal ring 2 places on screwed pipe plug 3 end face outer sleeves 1 inboard thin walled tube 5 outer surfaces, and outer sleeve 1 is threaded with screwed pipe plug 3 and cooperates, outer sleeve 1 the inner intersects with thin walled tube 5 end faces, preferably this infall have that interior projection 6 shoulder rank make thin walled tube 5 cover is fashionable can be not excessive, the outer sleeve 1 of this moment can be inner and thin walled tube 5 welding, for example with thin walled tube welding such as elbow or threeways, it also can be middle projecting inward sleeve pipe, this outer sleeve 1 two all can sheathed thin walled tube 5, and it is the most suitable to be used to connect straight tube.In the time of in thin walled tube 5 packs into outer sleeve 1, screw screwed pipe plug 3 and extrude seal ring 2, make seal ring 2 generation radial deformations couple together thin walled tube 5 and outer sleeve 1 securely and make it and seal.The pressure that produces in the time of standing seal ring 2 radial deformations for the end that makes thin walled tube 5, present embodiment adds inner sleeve 4, the preferably middle scrobicular ring that is provided with of this inner sleeve 4, this can make thin walled tube 5 generations " directional deformation " make connection more firm, these inner sleeve 4 end faces cooperate with thin walled tube 5 end faces shoulder rank, nonmetallic material manufacturings such as seal ring 2 usefulness nylon, plastics, four fluorine ethylenes, can be that filler is formed seal ring 2, also has multiple other structural type, for example be made up of two annular rings, also available a plurality of annular rings are formed.
