Abstract
The utility model discloses a kind of overall plastic threeway preventing leaking, comprise inner shafts and be the first straight length of interior threaded hole and the second straight length and the 3rd straight length to whole process, first straight length contacts the internal thread on connection the 3rd straight length respectively with interior threaded hole one side on the second straight length, and the remaining part do not contacted between the first straight length, the second straight length and the 3rd straight length is connected by arc body integrated injection molding; The first described straight length, is equipped with circular jogger hole outside the second straight length and the 3rd straight length, and jogger hole surface is provided with arc and arches upward or waveform arches upward.The utility model is by three Full Thread FT endoporus contacted with each other in the first straight length, the second straight length and the 3rd straight length, after pipeline is screwed, some contacts with each other, decrease the leak source leaked in pipeline connection procedure, substantially increase the technical performance preventing from leaking, and adopt jogger hole structure to avoid the circularity change of threeway endoporus.
Description
Technical field
The utility model relates to a kind of pipe connecting part, specifically a kind of overall plastic threeway preventing leaking.
Background technique
Joint all to be used in traditional pipeline connection procedure to carry out pipeline connection, particularly need when tube furcation to use threeway to connect.Its material of existing threeway can be divided into metal, plastics or metal and plastics compound, metal current threeway due to expensive and exist get rusty, the technology disadvantage such as corrosion, exit plumbing pipe industry gradually.Metal and plastics composite tee and the main Problems existing of plastic three-way be exactly plastic three-way its in injection moulding process, there is shrinkage, often cause the circularity of precision and elbow endoporus to be guaranteed, often occur seepy question.How to manufacture and a kind ofly prevent the threeway of leaking from being the object that those skilled in the art study.
The Chinese utility model patent patent No.: 201320762880.7 disclose a kind of plastic tube tee union, its three connecting port cylindricals are provided with end step, end step is provided with the stiffening ring of twice projection, circumferentially evenly stiffening rib is set between two stiffening rings, the endoporus of connecting port is taper hole, and the port part diameter of endoporus is greater than inner stopper place diameter.Although this kind of plastic three-way improves airtight performance by stiffening ring and carry out waterproof, structure is relatively single.
Summary of the invention
The utility model provides the overall plastic threeway preventing leaking that a kind of structure is simple, leak source is few, circularity is good.
A kind of overall plastic threeway preventing leaking, comprise the first straight length and second straight length of integrated injection molding, first straight length and the second straight length are positioned on same axis, the 3rd crossing straight length is provided with between first straight length and the second straight length, the first described straight length, second straight length and the 3rd straight length inner shafts are interior threaded hole to whole process, first straight length contacts the internal thread on connection the 3rd straight length respectively with interior threaded hole one side on the second straight length, first straight length, the remaining part do not contacted between second straight length and the 3rd straight length is connected by arc body integrated injection molding, the internal thread on connection the 3rd straight length is contacted respectively due to the first straight length and interior threaded hole one side on the second straight length, and above-mentioned internal thread is at the first straight length, omnidistance tapped hole is in second straight length and the 3rd straight length, thus achieve after the pipeline be connected with the first straight length and the second straight length and the 3rd straight length screws that some contacts with each other, decrease the leak source leaked in pipeline connection procedure, substantially increase the technical performance preventing from leaking.Circular jogger hole is equipped with outside the first described straight length, the second straight length and the 3rd straight length, jogger hole surface is provided with arc and arches upward or waveform this kind of jogger hole structure that arch upward avoids push rod jack-up threeway in traditional injection moulding process, by the technological deficiency of the distortion on the endoporus top of threeway, to be arched upward by arc or waveform arches upward and effectively dissolved the jack-up impact force of push rod, avoid the circularity of threeway endoporus to change.
The first described straight length, the second straight length and the 3rd straight length end face are equipped with expanding port, are provided with arc angling outside expanding port.Expanding port organization adds the anti-pressure ability of connecting end, avoids occurring cruelly splitting seepy question, and arc angling structure is by increasing area of contact, is further airtightly connected to pipeline.
Be provided with expanding annulus inside described first straight length, the second straight length and the 3rd straight length end face, increase the flow of current in threeway, prevent line clogging.
The utility model is by three Full Thread FT endoporus contacted with each other in the first straight length, the second straight length and the 3rd straight length, after pipeline is screwed, some contacts with each other, decrease the leak source leaked in pipeline connection procedure, substantially increase the technical performance preventing from leaking, and adopt jogger hole structure to avoid the circularity change of threeway endoporus.
Accompanying drawing explanation
Be illustrated in figure 1 the overall plastic threeway perspective view that the utility model prevents from leaking.
Embodiment
A kind of overall plastic threeway preventing leaking as shown in Figure 1, comprise the first straight length 2 and the second straight length 3 of integrated injection molding, first straight length 2 and the second straight length 3 are positioned on same axis, the 3rd crossing straight length 1 is provided with between first straight length 2 and the second straight length 3, first straight length 2, second straight length 3 and the 3rd straight length 1 inner shafts are interior threaded hole to whole process, first straight length 2 contacts the internal thread on connection the 3rd straight length 1 respectively with interior threaded hole one side on the second straight length 3, first straight length 2, the remaining part do not contacted between second straight length 3 and the 3rd straight length 1 is connected by arc body 4 integrated injection molding, to reduce the leak source in pipeline connection procedure.Be equipped with circular jogger hole 5 outside first straight length 2, second straight length 3 and the 3rd straight length 1, jogger hole 5 surface is provided with arc and arches upward or waveform arches upward, and prevents push rod by the distortion on threeway endoporus top.
As structure preferably the first straight length 2, second straight length 3 and the 3rd straight length 1 end face be equipped with expanding port, be provided with arc angling outside expanding port.
In order to the flow improving threeway prevents blocking, inside the first straight length 2, second straight length 3 and the 3rd straight tube 1 section of end face, be provided with expanding annulus.
