Abstract
The utility model is an Al-plastic pipe connecting structure, relating to the technical field for pipeline connection. The utility model comprises a joint, a pressing nut and a connected Al-plastic pipe, is characterized in that a pressing nut, a butterfly spring washer, a lock ring and an O-shaped seal ring connected on the outer wall of Al-plastic pipe in turn, a plug and a connection from inside to outside for connected end and joint, a pressing screw cap pressing tightly to the butterfly spring washer which is connected with the joint by screw. The Al-plastic pipe connecting structure is simple, easily assembling, low production cost and good for environment protection.
Description
Technical field
The utility model relates to the pipeline connection technology field, is specially a kind of plastic-aluminum pipe connecting structure.
Background technique
Plastic-aluminum pipe (aluminium-plastic composite pipe) is a kind of tubing that generally adopts in the prior art, and its moderate cost, light weight, durable are because the bendability characteristics of plastic-aluminum pipe makes construction and installation convenient.In addition, a large amount of uses of solar water heater and the increase of building gas pipe, service pipe, indoor pipe application quantity further improve the installation and the quality requirement of corresponding tubing, and the plastic-aluminum pipe has satisfied the usage requirement of this respect preferably, are one of preferential novel tubes of recommending of the Ministry of Construction.But existing plastic-aluminum pipe, usually adopt the structure of copper sleeve cutting ferrule connection, be provided with inner core, inner core seal ring, copper snap ring in the copper sleeve, the plastic-aluminum pipe box is connected on the inner core, clamping nut reaches sealing effect by pressing snap ring, its complex structure, the assembling loaded down with trivial details, the cost of material height, the easy pig copper rust of long-time use influences water quality.
The model utility content
For overcoming the above-mentioned problems in the prior art, the utility model design provides a kind of technological scheme of plastic-aluminum pipe connecting structure simple in structure, easy for installation.
Described plastic-aluminum pipe connecting structure, comprise connecting head, clamping nut and connected plastic-aluminum pipe, it is characterized in that on the plastic-aluminum pipe outer wall that socket is provided with clamping nut, dish-shaped bullet pad, back-up ring, O RunddichtringO successively, plastic-aluminum pipe connecting end cooperates with inside and outside the pegging graft of connecting head, and clamping nut presses dish-shaped bullet pad and connecting head threaded.
Described plastic-aluminum pipe connecting structure is characterized in that the thin ring structure of taper that dish-shaped bullet pad is made for the sheet metal punching press, and its awl limit edge inserts between the inside and outside wall of back-up ring and plastic-aluminum pipe.
Described plastic-aluminum pipe connecting structure is characterized in that connecting head is straight joint, elbow connection or tee union.
Above-mentioned plastic-aluminum pipe connecting structure, simple in structure, easy to assembly, cost of production is low, is beneficial to environmental protection.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in the figure, on plastic-aluminum pipe 5 outer walls successively socket clamping nut 6, dish-shaped bullet pad 4, back-up ring 3, O RunddichtringO 2 are set, plastic-aluminum pipe 5 connecting ends and connecting head 1 inside and outside pegging graft cooperates, clamping nut 6 presses dish-shaped bullet pad 4 and connecting head 1 threaded.The straight joint that connecting head 1 is made for plastics, elbow connection or tee union have reduced cost of production, and can not get rusty.The thin ring structure of taper that dish bullet pad 4 is made for the sheet metal punching press, its awl limit edge inserts between the inside and outside wall of back-up ring 3 and plastic-aluminum pipe 5.Press down at clamping nut 6, dish-shaped bullet pad 4 tightly nips plastic-aluminum pipe 5, and pressure is tight more more, plays the effect that close-fitting connects.
