Abstract
The invention refers to a kind of pip which is used to connect with the plastic steel pipe, which is mainly applied to the supplying and discharging of fluid, the connection part of the pipe screw connection piece is made up of a hollow cylinder and a hollow circle platform, the plastic steel pipe covers out of the hollow cylinder, the lining covers the outer surface of the plastic steel pipe and under the hollow cylinder, a circlip is set in the concave slot of the plastic steel pipe, the cover covers the plastic steel pipe and connected with the pipe screw connection piece. The merits of the invention are: at first, it needn't any flaring device, it can realize the connection; second, it not only applies to civil pipe, but also applies to industry pipe; the third, the operation is convenient.
Description
Technical field:
The present invention relates to a kind of pipe fitting of being connected with plastic steel pipe of being used for, be mainly used in the supply and the discharging of fluid, belong to tubular union and make the field.
Background technique:
All number of patent application 03100833.X of the applicant, title " the stainless steel pipeline link that is used for the plastic steel composite pipe road ", its pipe connecting body adopts stainless steel, plastic steel composite pipe connecting body in the pipe connecting body is hollow round table-like, be positioned on the pipe connecting body at plastic steel composite pipe connecting body rear portion and be shaped on screw thread, stainless steel card pipe reducing nut is screwed on the screw thread.Encapsulating method: be positioned at stainless steel card pipe reducing nut and stainless steel card pipe reducing connecting body the plastic steel composite pipe connecting body about two ones end form line with the enlarging inwall of plastic steel composite pipe respectively, face combines, when stainless steel card pipe reducing nut was tightened on stainless steel card pipe reducing connecting body, the end of plastic steel composite pipe connecting body formed line with the enlarging inwall of plastic steel composite pipe, face seal combines.Its deficiency: plastic steel pipe needs enlarging equipment when connecting with tubular union, for the user of industrial pipe, its ability to bear still can, for commercial tubes, its purchase and use of protecting jaws equipment exists certain difficulty and inconvenience.
Summary of the invention:
Purpose of design: design a kind of enlarging equipment that need not, can realize plastic steel composite pipe tubular union and crush seal method that plastic steel pipe connects with the tubular union reliable sealing.
Design proposal: 1. the joint of pipe thread link is made of hollow cylinder and hollow round platform, it is one of feature of the present invention, both can guarantee that pipe thread link open circles cylinder was connected with the reliable sealing of plastic steel pipe, and can need enlarging equipment that plastic steel pipe is carried out enlarging again; 2. lining is set on the outer wall of plastic steel pipe end is two of feature of the present invention, when purpose makes the inherent compressive deformation of the tube wall of plastic steel pipe, its outer wall remains unchanged, the open circles cylinder in inwall and the pipe thread link forms high pressure sealing and combines, thereby improves its crushing resistance.3. Baltimore groove is set and the structural design of jump ring is set in Baltimore groove at the plastic steel pipe joint, it is three of feature of the present invention, purpose is under the effect of overcoat and pipe thread link, strengthens its pulling capacity, guarantees that plastic steel pipe is connected with the reliable sealing of pipe thread link.
Technological scheme 1: plastic steel composite pipe tubular union, the joint of pipe thread link (1) is made of hollow cylinder (6) and hollow round platform (7), plastic steel pipe (5) is enclosed within on the hollow cylinder (6), lining (3) is enclosed within on the outer wall of plastic steel pipe and is positioned at the hollow cylinder top, jump ring (4) is stuck in the groove of plastic steel pipe, and overcoat (2) is enclosed within on the plastic steel pipe and with the pipe thread link and spins.
Technological scheme 2: the crush seal method of steel-plastic composite pipe tubular union, according to claim 1, lining is enclosed within on the tube wall of plastic steel pipe end, the plastics of plastic steel pipe end inwall are forced to be enclosed within on the hollow cylinder of pipe thread link and are formed sealing with the open circles cylinder and combine by extrusion-deformation, jump ring is stuck in the groove of plastic steel pipe, overcoat is enclosed within on the plastic steel pipe, the inwall of its overcoat forms clamping with jump ring on being positioned at plastic steel pipe and cooperates, to stop plastic steel pipe to be subjected to displacement, the internal thread of overcoat and pipe thread link are forced to spin, and make the plastic steel pipe inwall form sealing with the open circles cylinder of pipe thread link and combine.
The present invention compares with background technique, and the one, need not any enlarging equipment, can realize that plastic steel pipe connects with the reliable sealing of pipe thread link; The 2nd, be not only applicable to civilian using and manage, and be applicable to industrial pipe; The 3rd, easy to operate, easy to utilize, obtained beyond thought economic benefit and social benefit.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the structural representation of pipe thread link.
Embodiment:
Embodiment 1: with reference to attached Fig. 1 and 2.The plastic steel composite pipe tubular union, the joint of pipe thread link 1 is made of hollow cylinder 6 and hollow round platform 7, plastic steel pipe 5 is enclosed within on the hollow cylinder 6, lining 3 is enclosed within on the outer wall of plastic steel pipe 5 and is positioned at hollow cylinder 6 tops, jump ring 4 is stuck in the groove of plastic steel pipe 5, and overcoat 2 is enclosed within on the plastic steel pipe 5 and with pipe thread link 1 and spins.The inboard of one end of pipe thread link 1 has internal thread, is mainly used in outer tube and is connected (as having the steel pipe of screw thread or tubular union or the like).After pipe thread link 1 and overcoat 2 adopted the casting technique casting, processing got final product.Lining 3 and jump ring 4 adopt prior art to make, and are not described herein at this.Plastic steel pipe 5 is adopted all pipelines of the applicant and is made, and during installation, its pipe jointing part rolls fluted.
Embodiment 2: the crush seal method of steel-plastic composite pipe tubular union, according to claim 1, lining is enclosed within on the tube wall of plastic steel pipe end, the plastics of plastic steel pipe end inwall are forced to be enclosed within by extrusion-deformation to form on the hollow cylinder of pipe thread link and with the open circles cylinder and are tightly connected, jump ring is stuck in the groove of plastic steel pipe, overcoat is enclosed within on the plastic steel pipe, the inwall of its overcoat forms clamping with jump ring on being positioned at plastic steel pipe and cooperates, to stop plastic steel pipe to be subjected to displacement, the internal thread of overcoat and pipe thread link are forced to spin, and make the plastic steel pipe inwall form sealing with the open circles cylinder of pipe thread link and combine.
What need understand is: the foregoing description is just to explanation of the present invention, rather than limitation of the present invention, and any innovation and creation that do not exceed connotation of the present invention all fall within the scope of protection of the present invention.
