Abstract
The utility model discloses a kind of pipe line made up of full plastics reducing connection set, comprise the first interior threaded hole aperture that the first joint is provided with and be greater than the first male-pipe; The first described male-pipe connects the second interior threaded hole on the second joint, the second joint the other end is provided with the 3rd interior threaded hole that aperture is greater than the second interior threaded hole, 3rd interior threaded hole connects the second male-pipe on the 3rd joint, and the 3rd joint is provided with the 3rd male-pipe; Be provided with circular jogger hole outside the first described joint and the 3rd joint, jogger hole surface is provided with arc and arches upward or waveform arches upward.The utility model is by the repeatedly reducing of interconnective first joint, the second joint, the 3rd joint, form repeatedly the technical pattern of reducing, to adapt to the repeatedly change requirement of pipe diameter, and 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 the first joint and the 3rd coupler bore to change.
Description
Technical field
The utility model relates to a kind of pipe connecting part, specifically a kind of pipe line made up of full plastics reducing connection set.
Background technique
Joint all to be used in traditional pipeline connection procedure to carry out pipeline connection, particularly often need the joint using reducing when pipeline generation diameter changes.Its material of existing reducer union can be divided into metal, plastics or metal and plastics compound, metal current reducer union due to expensive and exist get rusty, the technology disadvantage such as corrosion, exit plumbing pipe industry gradually.Metal and the reducer union of plastics compound and the main Problems existing of plastics reducer union be exactly plastics reducer union its in injection moulding process, there is shrinkage, often cause the circularity of precision and reducer union endoporus to be guaranteed, often occur seepy question.How to manufacture and a kind ofly prevent the reducer union of leaking from being the object that those skilled in the art study.In addition existing reducer union its only there is a reducing ability, reducing technical requirements repeatedly cannot be adapted to.
Summary of the invention
The utility model provides that a kind of structure is simple, leak source is few, circularity well can the pipe line made up of full plastics reducing connection set of repeatedly reducing.
A kind of pipe line made up of full plastics reducing connection set, comprise the first joint, the second joint, the 3rd joint that connect successively, first described joint one end is provided with the first male-pipe, the other end is provided with the first interior threaded hole, first interior threaded hole aperture is greater than the first male-pipe, form the pipeline concatenation ability of two kinds of diameters, reach first time reducing object.The first described male-pipe is threaded the second interior threaded hole on the second joint, and the second joint the other end is provided with the 3rd interior threaded hole that aperture is greater than the second interior threaded hole, forms the third caliber, reaches second time reducing object.3rd interior threaded hole is threaded the second male-pipe on the 3rd joint, the 3rd joint the other end is provided with the 3rd male-pipe, the 3rd described male-pipe aperture is greater than or less than the second male-pipe, form the 4th kind of caliber, reach third time reducing object, form repeatedly the technical pattern of reducing, to adapt to the repeatedly change requirement of pipe diameter.The second described interior threaded hole and the 3rd interior threaded hole axially contact with each other and run through the second joint, reduce the first male-pipe, the leak source of the first male-pipe in connection procedure, prevent from leaking.Be provided with circular jogger hole outside the first described joint and the 3rd joint, jogger hole surface is provided with arc and arches upward or waveform arches upward.This kind of jogger hole structure avoids push rod in traditional injection moulding process, jack-up first joint and the 3rd joint are by the technological deficiency of the distortion on endoporus top, 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 the first joint and the 3rd coupler bore to change.
Be provided with expanding annulus as inside structure preferably the second interior threaded hole end face, annulus is built-in with seal ring, increases the flow of current in the second interior threaded hole, prevents line clogging, and improve sealability.
The utility model is by the repeatedly reducing of interconnective first joint, the second joint, the 3rd joint, form repeatedly the technical pattern of reducing, to adapt to the repeatedly change requirement of pipe diameter, and 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 the first joint and the 3rd coupler bore to change.
Accompanying drawing explanation
Be illustrated in figure 1 the utility model pipe line made up of full plastics reducing connection set solid and blow mounting structure schematic diagram.
Embodiment
A kind of pipe line made up of full plastics reducing connection set as shown in Figure 1, comprise the first joint 3, second joint 2, the 3rd joint 1 that connect successively, first joint 1 one end is provided with the first male-pipe, the other end is provided with the first interior threaded hole, and the first interior threaded hole aperture is greater than the first male-pipe and forms first time reducing.First male-pipe is threaded the second interior threaded hole on the second joint 2, and the second joint the other end is provided with the 3rd interior threaded hole that aperture is greater than the second interior threaded hole, forms second time reducing.3rd interior threaded hole is threaded the second male-pipe on the 3rd joint 1, the 3rd joint the other end is provided with the 3rd male-pipe, 3rd male-pipe aperture is greater than or less than the second male-pipe and forms third time reducing, to adapt to the repeatedly diameter change of pipeline.
Be provided with circular jogger hole 4 outside first joint 3 and the 3rd joint 1, jogger hole 4 surface is provided with arc and arches upward or waveform arches upward, and prevents the endoporus circularity of the first joint 3 and the 3rd joint 1 from changing.Second interior threaded hole and the 3rd interior threaded hole axially contact with each other and run through the second joint 2, to reduce the leak source in connection procedure.
In order to expand flow and improve sealability, be provided with expanding annulus inside the second interior threaded hole end face, annulus is built-in with seal ring.
Claims (3)
1. a pipe line made up of full plastics reducing connection set, comprise the first joint, the second joint, the 3rd joint that connect successively, it is characterized in that: first described joint one end is provided with the first male-pipe, and the other end is provided with the first interior threaded hole, and the first interior threaded hole aperture is greater than the first male-pipe; The first described male-pipe is threaded the second interior threaded hole on the second joint, the second joint the other end is provided with the 3rd interior threaded hole that aperture is greater than the second interior threaded hole, 3rd interior threaded hole is threaded the second male-pipe on the 3rd joint, and the 3rd joint the other end is provided with the 3rd male-pipe; Be provided with circular jogger hole outside the first described joint and the 3rd joint, jogger hole surface is provided with arc and arches upward or waveform arches upward; The second described interior threaded hole and the 3rd interior threaded hole axially contact with each other and run through the second joint.
