Abstract
The utility model relates to a pipe joint, particularly a pipe joint with a variable nominal diameter. A diameter variable connector for plastic pipelines is composed of a main pipe joint pipe and a branch pipe joint pipe which are integrated into one body, wherein the internal diameter of the branch pipe joint pipe is greater than or equal to the internal diameter of the main pipe joint pipe. The utility model has the advantages of simpler structure, smooth pipeline with little possibility of blocking, low cost, arbitrarily variable nominal diameter, etc. The utility model can be widely used in water treating, water supplying and discharging devices, gas distributing plastic pipelines and water distributing plastic pipelines, and can also be used in the fields of chemical industry, etc.
Description
The utility model relates to pipe joint, especially the variable pipe joint of nominal diameter.
Connection pattern commonly used has flange connection, scyewed joint, welding, stuffing box formula to connect in the pipeline, spigot and socket type connects, clamp band type connects and FERRULETYPE connects.With the scyewed joint is example, and existing nominal is variable pipe joint directly, and for example reducing tee, reducing cross etc. when using, all will be cut off the person in charge in pipeline connects, if when being responsible for nominal diameter with arm and differing big, just can match through reducing repeatedly.Exist that structure is complicated, pipeline easily stops up, the more high disadvantage of cost.
The purpose of the utility model is to disclose that a kind of structure is simple, pipeline is difficult for stopping up, cost is lower, nominal directly claims any variable new tube joint.
Plastic pipeline reducing connecting piece is responsible for adapter by all-in-one-piece and the arm adapter is formed, and the internal diameter that arm is taken over is more than or equal to being responsible for the internal diameter of taking over.
Below in conjunction with embodiment shown in the drawings, the utility model will be further described.
Accompanying drawing 1 is the utility model embodiment one a plan view, accompanying drawing 2 is plan views of the utility model embodiment one, accompanying drawing 3 is right elevations of the utility model embodiment one, accompanying drawing 4 is plan views of the utility model embodiment two, accompanying drawing 5 is plan views of the utility model embodiment three, and accompanying drawing 6 is the utility model embodiment one user mode plan views.
Shown in accompanying drawing 1 to 6, plastic pipeline reducing connecting piece 6 is responsible for adapter 1 by all-in-one-piece and arm adapter 2 is formed.Arm is taken over 2 internal diameter more than or equal to the internal diameter of being responsible for adapter 1.Embodiment one and two arm are taken over 2 internal diameter and are taken over 1 internal diameter greater than being responsible for, and after arm 7 inserted arms and takes over 2, the internal diameter of arm 7 equals to be responsible for took over 1 internal diameter.The internal diameter of embodiment three arm adapter 2 equals to be responsible for takes over 1 internal diameter, connects because arm 7 is taken over 2 usefulness flanges with arm, and the internal diameter of arm 7, arm adapter 2 and person in charge's adapter 1 is all identical.
Shown in accompanying drawing 1,4,5 and 6, being responsible for and taking over 1 can be light pipe, also outside thread can be arranged, and can there be the reinforcer 3 of circle, ellipse, polygonal or other geometrical shapies the outside of light pipe.It is light pipe that embodiment one and three be responsible for to take over 1, is fixed on method such as bonding and is responsible on 5, and there is circular reinforcer 3 outside of light pipe, and reinforcer 3 also is fixed on the person in charge 5 with method such as bonding, as shown in Figure 6.There is screw thread the outside that embodiment two is responsible for adapter 1, is screwed on the person in charge 5 the tapped hole.
Shown in accompanying drawing 1,4,5 and 6, it is light pipe that arm takes over 2, and internal thread is perhaps arranged, and outside thread is perhaps arranged, and flange 4 is perhaps arranged.It is light pipe that embodiment one arm takes over 2, and arm 7 just is inserted in the light pipe adapter 2, fixes with method such as bonding, as shown in Figure 6.Embodiment two arm takes over 2 internal thread, is with externally threaded arm 7 just to be screwed in arm and takes in 2.Embodiment three arm takes over 2 flange 4.Flange 4 can be taken over 2 with arm and be integral, and also can be fixed on arm with method such as bonding and take on 2.Flanged (FLGD) arm 7 is taken over 2 usefulness flanges with arm and is connected.
Series product are made in the utility model plastics once-through.
Obviously, the utility model need not cut off and be responsible for 5 when installing and using, as long as perforate just can on the person in charge 5.From being responsible for 5 to arm 7, nominal diameter can change arbitrarily, as long as change the interior external diameter of being responsible for adapter 1 and arm adapter 2.Have advantages such as structure is simple, the smooth and easy difficult obstruction of pipeline, cost is lower, nominal diameter can change arbitrarily, can be widely used in water treatment, the water feeding and draining device gas distribution water distribution plastic piping, also can be used for fields such as chemical industry.
In the embodiment shown in the figures, it is φ 25 that embodiment one the person in charge takes over 1 internal diameter size, and it is φ 32 that arm is taken over 2 internal diameter sizes, and it is φ 30 that embodiment two the person in charge takes over 1 internal diameter size, and it is φ 40 that arm is taken over 2 internal diameter sizes; Embodiment three the person in charge take over 1 and arm take over 2 internal diameter size and be φ 40.
