Abstract
The utility model relates to a pipe connection component of the fluid pressure and air pressure actuator of the mechanical engineering. On the installed pipes of tap water, range fume, and heating, if a fault especially a fault in a main pipe is discovered, the processing along the unmovable part in the pipe axial direction is difficult. Therefore, the utility model discloses a telescopic connecting pipe composed of a sleeve pipe sealing nut and a rubber ring, one end of the sleeve pipe is directly connected with a pipe passage, and the other end is connected with the pipe passage through the rubber ring and the sealing nut to serve for expansion joint.
Description
The utility model belongs to the tubular union of hydrodynamic pressure in the mechanical engineering, gas pressure actuator.On the tap water that has installed, kitchen range gas, heating pipeline, as find that certain pipe fitting or pipeline section break down and need to change.If this faulty section appears at the terminal of whole pipe, directly replacing gets final product; If faulty section appears among the main pipe, promptly can not the section of moving along duct orientation, make it can't loading or unloading pipeline section or pipe fitting.The way that solves, the most stupid least desirable way are whole full pipeline to be removed reinstall, and this is impossible certainly.Existing common way is sawed-off at its faulty section, adorning one common " mimeograph " that we are commonly called as connects pipeline by " mimeograph " again, because the axial distance that " mimeograph " is adjustable is too little, by dress " mimeograph " pipelines on two sides the time, must there be a pipeline tilting to insert, and then it is fastening, pipeline tilting installation method can also adapt to for the access than long tube like this, and just bigger for the access difficulty of short distance pipeline, to such an extent as to develop into infeasible stage." mimeograph " side joint pipeline length of going into is difficult to transfer suitablely in a word, even transfer appropriately, owing to also can produce tension force after fastening " mimeograph ", causes the danger of damage to pipeline.Use when the purpose of this utility model is to overcome existing maintenance pipeline " mimeograph " make it pipeline length should not mix up with fastening " mimeograph " after to make pipeline produce the danger design that tension force causes pipeline to damage a kind of by sleeve pipe, the scalable connection pipe fitting that envelope jack panel and rubber ring are formed.The utility model is mainly realized by following structure: it is made up of sleeve pipe, envelope jack panel and cushion rubber.Described sleeve pipe is a CONCENTRIC REDUCER, and is shaped on internal thread respectively at two ends.The envelope jack panel is shaped on outside thread, and can screw in the sleeve pipe major part.The rubber ring pad is between envelope jack panel and sleeve pipe major part.Envelope jack panel internal orifice dimension, rubber ring internal diameter sleeve pipe cella are directly for just pass the pipeline that is connected with the sleeve pipe microcephaly.Screw thread is made along a thickness aspect part in above-mentioned envelope jack panel outer ring, and another part is made " hexagonal " or " anise " shape, and makes wedge being threaded an end.Hexagonal or octagon are made in the major part outer ring of described sleeve pipe.Use the scalable connection pipe fitting of the utility model design, fundamentally solved maintenance and be among the main pipe, promptly prolong the fault that duct orientation can not the place of moving appearance, and can finish at short notice.
Describe in detail below in conjunction with accompanying drawing.Accompanying drawing 1 is a structural representation of the present utility model.Fig. 2-the 5th, use scheme of installation of the present utility model.(1) sleeve pipe in the accompanying drawings, (2), envelope jack panel, (3) rubber ring (4) pipeline.Shown in the accompanying drawing 1, the utility model is by sleeve pipe (1), and envelope jack panel (2) rubber ring (3) is formed.Sleeve pipe is a CONCENTRIC REDUCER, and is shaped on internal thread respectively in two ends, and the gradual change form is not adopted in the CONCENTRIC REDUCER transition, and adopts the ladder transition.Big more between the CONCENTRIC REDUCER apart from the scalable scope of big more connection pipe fitting of the present utility model.Some makes outside thread to the envelope jack panel along thickness direction in its outside, and another part is made hexagonal or octagon.This outside thread can screw among the sleeve pipe major part.Make wedge shape being shaped on an externally threaded termination.Be used to compress the rubber ring that places between sleeve pipe major part and the envelope jack panel.Sleeve pipe cella diameter, envelope jack panel diameter of bore, the rubber ring inner ring diameter is advisable for the pipe that pipeline promptly is connected with the sleeve pipe microcephaly slides to pass.Its rubber ring internal diameter can be made into and is slightly smaller than envelope jack panel internal diameter and sleeve pipe cella footpath.With pipeline (4) diameter than drive fit, it is long greater than internal thread that envelope jack panel external thread length will be a bit larger tham sleeve pipe, seals jack panel and compress rubber ring so that add can make behind the rubber ring.
Specify of the present utility model installing and using below.Be the part of a main line as shown in Figure 2.If pipeline two is fixing, be that pipeline two ends or both sides have pipeline connected vertically with it, this part pipeline can not be moved along its axial direction, change three links wherein, at first with three links together with a part of pipeline saw down, this is by the long 45-65mm that generally gets of the pipeline under sawing.As shown in Figure 3, then envelope jack panel of the present utility model, rubber ring and sleeve pipe are enclosed within pipeline one end as shown in Figure 4 successively.Again new three links are contained in the pipeline the other end, and are connected with the sleeve pipe microcephaly by outer silk, at this moment pipeline (4) one ends in sleeve pipe (1), and moving axially can guarantee that sleeve pipe (1) microcephaly is connected with three links the time.As shown in Figure 5, at last rubber ring is pushed in the sleeve pipe, tighten, pipeline (4) can not be moved vertically, play seal action between pipeline and the sleeve pipe simultaneously with the envelope jack panel.The scalable connection pipe fitting of the utility model design is applicable to the civilian industrial pipeline of all size.By to the water supply pipe caliduct, the test of kitchen range feed channel, effect is fine.The difficulty that it has occurred when not only having solved the maintenance pipeline is not brought the poor problem of sealing simultaneously yet.
Claims (3)
1, a kind of scalable connection pipe fitting, by sleeve pipe (1), envelope jack panel (2) and rubber ring (3) are formed, and it is characterized in that sleeve pipe (1) is CONCENTRIC REDUCER, and are shaped on internal thread respectively at its two ends; The envelope jack panel
(2) be shaped on outside thread, and can screw in sleeve pipe (1) major part; The rubber ring pad is at the envelope jack panel
(2) and between the sleeve pipe major part; Envelope jack panel internal orifice dimension, rubber ring internal diameter, sleeve pipe cella are directly for just pass the pipeline (4) that is connected with the sleeve pipe microcephaly.
2, scalable according to claim 1 connection pipe fitting is characterized in that sealing jack panel.(2) screw thread is made along a thickness direction part in the outer ring, and another part is made hexagonal or octagon; And make wedge shape being threaded a termination.
