Description
Technical field
The present invention relates to pipe joint, be specifically related to a kind of aluminium-plastic composite pipe rapid pipe joint.
Background technique
At present, the on-the-spot aluminium-plastic composite pipe Placement used, adopt spigot and socket type, flange-type or pipe thread formula more, link used is generally made with metallic material, and their corrosion resistancies are poor, often in the lifetime of body, joint area just damages because of corrosion prematurely, leaks, cause damage, and when installing, site operation speed is slow, workmen's labor intensity is large.In addition, these three kinds of mode connection construction times are long, also want supporting relevant construction tool, and require higher to constructing operation person, complicated operation, easily occurs operate miss, problem during installation fee.
Summary of the invention
The object of the present invention is to provide and a kind of aluminium-plastic composite pipe rapid pipe joint quick, corrosion-resistant and simple to operate is installed.
For achieving the above object, technological scheme of the present invention is as follows: aluminium-plastic composite pipe rapid pipe joint, comprise sleeve and connected element, described connected element comprises integrated interior steel belt layer and fiberglass plastic layer from outside to inside, sleeve is provided with pipeline slot and outside outward flange, pipeline slot is provided with down kerf, kerf of falling is interior is disposed with shackle member and clamp ring along the bottom of pipeline slot on notch direction, the cell wall of kerf and the outer wall of clamp ring are conical surface and contact with each other, the inwall of fiberglass plastic layer is provided with the inner groovy matched with outward flange.
The principle of this programme: during operation, pipeline slot is for inserting the pipe fitting needing to connect, when pipe fitting is inserted pipeline slot and firmly drawing time, first shackle member can be blocked pipe fitting rapidly and follow pipe fitting and outwards offset, shackle member also can drive clamp ring outwards to offset together simultaneously, but because the cell wall of kerf and the outer wall of clamp ring are conical surface, this cuts effect with regard to making down kerf have to the card of clamp ring, this effect can stop rapidly the movement of shackle member and clamp ring, and clamp ring is constantly tightened up so that tightly pin pipe fitting, thus pipe fitting is connected in the rapid pipe joint of this aluminium-plastic composite pipe firmly.In addition, connected element be by interior steel belt layer and fiberglass plastic layer integrated, fiberglass plastic layer can play good anticorrosion ability, long service life, also can reveal by anti-water stopping tube simultaneously, inner groovy on fiberglass plastic layer inwall and the outward flange on pipeline match, and can play the spacing effect with locating fast.
The advantage of this programme is: the quick-fit location of outward flange on the inner groovy on fiberglass plastic layer inwall and pipeline, and have by falling kerf effect is cut to the card of clamp ring, stop the movement of shackle member and clamp ring, clamp ring is constantly tightened up so that tightly pin pipe fitting, whole process makes this aluminium-plastic composite pipe rapid pipe joint have installation fast, advantage simple to operate; Meanwhile, the fiberglass plastic layer in connected element can play good anticorrosion ability, long service life, also can reveal by anti-water stopping tube.
Further, described shackle member includes snap ring and back-off slideproof tooth, back-off slideproof tooth is evenly equipped with several along snap ring circumference, and back-off slideproof tooth closes up towards the medial axis inclination of snap ring, such setting just makes back-off slideproof tooth can guiding pipe elements insert in pipeline slot easily on the one hand, and another aspect effectively can be blocked pipe fitting again and stop the outside skew of pipe fitting.
Further, the joint of described connected element and sleeve is provided with ring for the sealing liquid and seal ring, guarantees the sealing that pipeline junction is good.
Accompanying drawing explanation
Fig. 1 is the structural representation of aluminium-plastic composite pipe rapid pipe joint embodiment of the present invention;
Fig. 2 is the schematic diagram of shackle member in aluminium-plastic composite pipe rapid pipe joint embodiment of the present invention;
Fig. 3 is the schematic diagram of clamp ring in aluminium-plastic composite pipe rapid pipe joint embodiment of the present invention.
Embodiment
Below by embodiment, the present invention is further detailed explanation:
Reference character in Figure of description comprises: sleeve 1, interior steel belt layer 2, fiberglass plastic layer 3, pipeline slot 4, outward flange 5, kerf 6, shackle member 7, snap ring 71, back-off slideproof tooth 72, clamp ring 8, inner groovy 9, ring for the sealing liquid 10, seal ring 11.
Embodiment is basic as accompanying drawing 1, shown in Fig. 3: aluminium-plastic composite pipe rapid pipe joint, comprise sleeve 1 and connected element, described connected element comprises integrated interior steel belt layer 2 and fiberglass plastic layer 3 from outside to inside, sleeve 1 is provided with pipeline slot 4 and outside outward flange 5, pipeline slot 4 is provided with down kerf 6, on notch direction, be disposed with shackle member 7 and clamp ring 8 along the bottom of pipeline slot 4 in kerf 6, by reference to the accompanying drawings shown in 2, shackle member 7 includes snap ring 71 and back-off slideproof tooth 72, back-off slideproof tooth 72 is evenly equipped with multiple along snap ring 71 circumference, and back-off slideproof tooth 72 closes up towards the medial axis inclination of snap ring 71, the cell wall of kerf 6 and the outer wall of clamp ring 8 are conical surface and contact with each other, the inwall of fiberglass plastic layer 3 is provided with the inner groovy 9 matched with outward flange 5, the joint of connected element and sleeve 1 is provided with ring for the sealing liquid 10 and seal ring 11.
In the present embodiment, during operation, pipeline slot 4 is for inserting the pipe fitting needing to connect, when pipe fitting is inserted pipeline slot 4 and firmly drawing time, first shackle member 7 can be blocked pipe fitting rapidly and follow pipe fitting and outwards offset, shackle member also can drive clamp ring 8 outwards to offset together simultaneously, but because the cell wall of kerf 6 and the outer wall of clamp ring 8 are conical surface, this cuts effect with regard to making down kerf 6 have to the card of clamp ring 8, this effect can stop rapidly the movement of shackle member 7 and clamp ring 8, and clamp ring 8 is constantly tightened up so that tightly pin pipe fitting, thus pipe fitting is connected in the rapid pipe joint of this aluminium-plastic composite pipe firmly.In addition, connected element be by interior steel belt layer 2 and fiberglass plastic layer 3 integrated, fiberglass plastic layer 3 can play good anticorrosion ability, long service life, also can reveal by anti-water stopping tube simultaneously, inner groovy 9 on fiberglass plastic layer 3 inwall and the outward flange 5 on pipeline match, and can play the spacing effect with locating fast.
