Abstract
The utility model relates to a two -layer structure inside and outside compound elbow of stainless steel, the body of elbow are divided into, inlayer are nonrust steel pipe, and be outer for the plastics elbow body, ectonexine composite component integrative, the elbow both ends that compound there is the bellmouth, the bellmouth internal diameter is greater than the stainless steel external diameter of pipe, the bellmouth is stretched into at nonrust steel pipe both ends, leaves the holding chamber promptly between nonrust steel pipe and the bellmouth internal diameter. The utility model discloses a stretch into the bellmouth so that leave the holding chamber between nonrust steel pipe and bellmouth internal diameter with nonrust steel pipe both ends, when tubular product was connected with the elbow hot melt, unnecessary plastics were clamp -oned the holding chamber and are avoided forming the bank at pipe inner wall, increase the joint strength of tubular product and elbow simultaneously.
Description
Technical field
The utility model relates to running water pipe pipe connecting field, particularly a kind of stainless steel composite elbow.
Background technique
Elbow is for changing the flow direction of water body, elbow of the prior art adopts plastic material, especially pvc pipe is the most common, in the process of conveying tap water, when water body is detained in elbow, the microbes precipitation in water body rests in elbow, cause producing secondary pollution to water quality, Long-Time Service can cause the decline of domestic water quality, and the microorganism therefore how realized in water body can flow away along with water body, becomes the problem that inventor needs to solve.Stainless steel composite elbow CN103899866A as open in Chinese patent is now also had to relate to the accessory that a kind of metallo-plastic composite elbow pipe fitting is the outer plastic drain-pipe of architecture indoor in order to improve water quality, belong to plastic composition pipeline field, it is that double layer construction is by metal bends internal layer and the outer complex group all-in-one-piece of plastic elbow.It adopts Stainless Steel Tube end face to flush with described bellmouth joint in joint, with tubing by hot-melt adhesive paste time, together with being formed with elbow joint at tubing, the bank of irregularity, not only affects water delivery, and easy in bank limit breed bacteria.
Model utility content
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of stainless steel composite elbow.
The utility model solves the technological scheme that its technical problem adopts: described a kind of stainless steel composite elbow, the body of elbow is divided into inside and outside double-layer structure, internal layer is Stainless Steel Tube, skin is plastic elbow body, described internal and external layer complex group is integral, and there is bellmouth at composite elbow two ends, and described bellmouth internal diameter is greater than Stainless Steel Tube external diameter, bellmouth is stretched at described Stainless Steel Tube two ends, namely leaves holding cavity between described Stainless Steel Tube and described bellmouth internal diameter.
By bellmouth being stretched at Stainless Steel Tube two ends to leave holding cavity between Stainless Steel Tube and described bellmouth internal diameter in above-mentioned design, when tubing and elbow hot-melt adhesive paste, unnecessary plastics are clamp-oned holding cavity and are avoided forming bank at inner-walls of duct, increase the join strength of tubing and elbow simultaneously.
As the further improvement of the design, it is 2-5mm that described Stainless Steel Tube stretches into described bellmouth length, is convenient to the plastics of accommodation melting and can prevents from forming a large amount of hole at holding cavity.
As the further improvement of the design, it is 2mm that described Stainless Steel Tube stretches into described bellmouth length.
As the further improvement of the design, it is 3mm that described Stainless Steel Tube stretches into described bellmouth length.
As the further improvement of the design, it is 5mm that described Stainless Steel Tube stretches into described bellmouth length.
As the further improvement of the design, described Stainless Steel Tube outer wall is provided with wire drawing lines or air marks, increases the join strength of Stainless Steel Tube and plastic elbow body.
As the further improvement of the design, described bellmouth inside and outside wall is equipped with along the axially extended projection of described bellmouth.Described bellmouth outer wall projection is convenient to clamping elbow to be connected with tubing, and described bellmouth inwall projection is convenient to tubing to insert elbow, easy for installation.
The beneficial effects of the utility model are: the utility model is by stretching into bellmouth by Stainless Steel Tube two ends to leave holding cavity between Stainless Steel Tube and described bellmouth internal diameter, when tubing and elbow hot-melt adhesive paste, unnecessary plastics are clamp-oned holding cavity and are avoided forming bank at inner-walls of duct, increase the join strength of tubing and elbow simultaneously.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is overall structure schematic diagram of the present utility model.
1. plastic elbow bodies in the drawings, 2. protruding, 3. bellmouth, 4. holding cavity, 5. Stainless Steel Tube.
Embodiment
The utility model is described in detail, illustrative examples wherein and illustrate and be only used for explaining the utility model below in conjunction with accompanying drawing and specific embodiment, but not as to restriction of the present utility model.
As shown in the figure, described a kind of stainless steel composite elbow, the body of elbow is divided into inside and outside double-layer structure, internal layer is Stainless Steel Tube 5, and skin is plastic elbow body 1, and described internal and external layer complex group is integral, there is bellmouth 3 at composite elbow two ends, described bellmouth 3 internal diameter is greater than Stainless Steel Tube 5 external diameter, and bellmouth 3 is stretched at described Stainless Steel Tube 5 two ends, namely leaves holding cavity 4 between described Stainless Steel Tube 5 and described bellmouth 3 internal diameter.
By bellmouth 3 is stretched into leave holding cavity 4 between Stainless Steel Tube 5 and described bellmouth 3 internal diameter in Stainless Steel Tube 5 two ends in above-mentioned design, when tubing and elbow hot-melt adhesive paste, unnecessary plastics are clamp-oned holding cavity 4 and are avoided forming bank at inner-walls of duct, increase the join strength of tubing and elbow simultaneously.
As the further improvement of the design, it is 2-5mm that described Stainless Steel Tube 5 stretches into described bellmouth 3 length, is convenient to the plastics of accommodation melting and can prevents from forming a large amount of hole at holding cavity 4.
As the further improvement of the design, it is 2mm that described Stainless Steel Tube 5 stretches into described bellmouth 3 length.
As the further improvement of the design, it is 3mm that described Stainless Steel Tube 5 stretches into described bellmouth 3 length.
As the further improvement of the design, it is 5mm that described Stainless Steel Tube 5 stretches into described bellmouth 3 length.
As the further improvement of the design, described Stainless Steel Tube 5 outer wall is provided with wire drawing lines or air marks, increases the join strength of Stainless Steel Tube 5 and plastic elbow body 1.
As the further improvement of the design, described bellmouth 3 inside and outside wall is equipped with along described bellmouth 3 axially extended protruding 2.Described bellmouth 3 outer wall projection 2 is convenient to clamping elbow to be connected with tubing, and described bellmouth 3 inwall projection 2 is convenient to tubing to insert elbow, easy for installation.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
