Abstract
The utility model relates to a compound tee bend of stainless steel, including three -way pipe, nonrust steel pipe, the three -way pipe includes first direct pipe, the direct pipe of second, the third is direct manages, and the stainless steel is intraductal to be served as a contrast in the three -way pipe, and each exit of three -way pipe all is equipped with holds the mouth of a river, holds mouth of a river internal diameter and is greater than the stainless steel external diameter of pipe, and nonrust steel pipe stretches into and holds the mouth of a river, and nonrust steel pipe forms the holding cavity with holding mouth of a river inner wall promptly, and nonrust steel pipe stretches into the direct pipe range degree of third and stretches into first direct pipe, the direct pipe range degree weak point of second. The utility model discloses have nonrust steel pipe to realize seamless butt joint with the butt joint of external tubular product after cross the sweat soldering at the direct pipe of first direct pipe, second, the direct intraductal equal inside lining of third, the holding cavity prevents that the plastics surplus behind the hot melt from forming the bank at the stainless steel inside pipe wall, effectively prevents to multiply the bacterium and does not influence the water delivery, and nonrust steel pipe stretches into that the direct pipe range degree of third stretches into first direct pipe, the direct pipe range degree of second is short, is convenient for a nonrust steel pipe side blanking play, and processing is convenient, saves raw and other materials.
Description
Technical field
The utility model relates to running water pipe pipe connecting field, particularly a kind of stainless steel composite tee.
Background technique
Threeway is a kind of pipe fitting for alter direction, be generally plastic material, its deficiency is that water body can produce microorganism after staying for some time in water pipe, microbes is adsorbed on link inwall, water quality is caused to produce secondary pollution, and adopting metal material Long-Time Service, scale can produce water quality equally and pollute, and cost is higher.The plastic composite pipe of stainless steel inner lining CN203500730U as open in Chinese patent is now also had to relate to a kind of threeway with internal thread structure, relate to running water pipe pipe connecting field and include water end (W.E.), waterexit end and water service pipe, described water service pipe is connected with described water intake end, waterexit end, described water intake end and described waterexit end be plastic material, described water service pipe is divided into internal layer and skin, described skin is polypropylene or polyethylene material, and described internal layer is stainless steel; The internal diameter of described water intake end is greater than the internal diameter of described waterexit end, and the inwall of described water intake end is inlaid with the internal thread of stainless steel, and the bottom of described internal thread is provided with projection, and described skin is heated by injection moulding and to be connected with described internal layer.Its stainless steel only in be lining in water service pipe, water intake end embed internal thread make to leave gap between internal thread and stainless steel inner lining, very easily occur bank when melting welding, easy breed bacteria, affects water delivery.
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 tee.
The utility model solves the technological scheme that its technical problem adopts: described a kind of stainless steel composite tee, comprise three-way pipe, Stainless Steel Tube, described three-way pipe comprises the first straight-through tube, second straight-through tube, 3rd straight-through tube, be lining in described Stainless Steel Tube in three-way pipe, each outlet port of described three-way pipe is equipped with holds the mouth of a river, the described mouth of a river internal diameter that holds is greater than described Stainless Steel Tube external diameter, described Stainless Steel Tube stretches into and holds the mouth of a river, namely described Stainless Steel Tube with hold mouth of a river inwall and form accommodating cavity, described Stainless Steel Tube stretches into the 3rd straight-through tube length and comparatively stretches into the first straight-through tube, second straight-through tube length is short.
Be lined with after Stainless Steel Tube docks with external tubing in equal in the first straight-through tube, the second straight-through tube, the 3rd straight-through tube in above-mentioned design and realize slitless connection through sweat soldering, plastics surplus after accommodating cavity prevents hot melt forms bank at stainless steel inside pipe wall, effectively prevents breed bacteria and does not affect water delivery.
As the further improvement of the design, holding mouth of a river length described in described Stainless Steel Tube stretches into is 2mm.
As the further improvement of the design, holding mouth of a river length described in described Stainless Steel Tube stretches into is 3mm.
As the further improvement of the design, described in hold bottom the mouth of a river as cambered surface, be convenient to the accommodating cavity of filling plastic and not easily form hole.
The beneficial effects of the utility model are: be lined with after Stainless Steel Tube docks with external tubing in the utility model is equal in the first straight-through tube, the second straight-through tube, the 3rd straight-through tube and realize slitless connection through sweat soldering, plastics surplus after accommodating cavity prevents hot melt forms bank at stainless steel inside pipe wall, effectively prevents breed bacteria and does not affect water delivery.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. first straight-through tubes in the drawings, 2. the 3rd straight-through tube, 3. the second straight-through tube, 4. Stainless Steel Tube, 5. hold the mouth of a river, 6. accommodating cavity, 7. cambered surface.
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.
Embodiment 1: as shown in the figure, described a kind of stainless steel composite tee, comprise three-way pipe, Stainless Steel Tube 4, described three-way pipe comprises the first straight-through tube 1, second straight-through tube 3, 3rd straight-through tube 2, be lining in three-way pipe in described Stainless Steel Tube 4, each outlet port of described three-way pipe is equipped with holds the mouth of a river 5, the described mouth of a river 5 internal diameter that holds is greater than described Stainless Steel Tube 4 external diameter, described Stainless Steel Tube 4 stretches into and holds the mouth of a river 5, namely described Stainless Steel Tube 4 with hold the mouth of a river 5 inwall and form accommodating cavity 6, described Stainless Steel Tube 4 stretches into the 3rd straight-through tube 2 length and comparatively stretches into the first straight-through tube 1, second straight-through tube 3 length is short, be convenient to go out at a Stainless Steel Tube 4 side stamping-out, easy to process, save raw material.
Be lined with after Stainless Steel Tube 4 docks with external tubing in equal in the first straight-through tube 1, second straight-through tube 3, the 3rd straight-through tube 2 in above-mentioned design and realize slitless connection through sweat soldering, accommodating cavity 6 prevents the plastics surplus after hot melt from forming bank at Stainless Steel Tube 4 inwall, effectively prevents breed bacteria and does not affect water delivery.
