Abstract
The utility model discloses a quick installing pipe joint with variable diameters, which is composed of a nut of a big pipe, a thread connector of a big pipe, a nut of a small pipe, a connector of a small pipe, big tapered semicircular rings, sealing rings of big pipe, a T-shaped thread connecting sleeve, small tapered semicircular rings and sealing rings of a small pipe, wherein an inner hole of the thread connector of a big pipe is a taper hole, big tapered semicircle rings of two big half clamping pipes are arranged in the taper hole, and the sealing rings of a big pipe are arranged in the big tapered semicircle rings. An inner hole of the connector of a small pipe is a taper hole, two small tapered semicircle rings are arranged in the taper hole, and the sealing rings of a small pipe are arranged in the small tapered semicircle rings. The utility model has the advantages of convenient construction, time saving and labor saving because threads do not need to be made on connected pipelines.
Description
The utility model relates to the diameter reducing type pipe coupling of two kinds of diameter pipelines that vary in size of a kind of connection.
At present, existing diameter reducing type pipe coupling generally all is to produce screw thread in the hole of its different-diameter, need on connected pipeline, produce the screw thread identical during use with pipe coupling, connected pipe could be connected with pipe coupling then, because this pipe coupling need produce screw thread in use on connected pipeline, therefore exist constructional difficulties, time-consumingly take a lot of work, use very inconvenient shortcoming.
The purpose of this utility model is: provide a kind of fast holding pipe joint of diameter reducing type that need not make screw thread on connected pipeline, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: it is by bassoon nut (1), bassoon threaded connector (2), tubule nut (3), little tubular union (4), the more than half annulus of taper (5), bassoon seal ring (7), the T type cover (8) that is threaded, taper smaller part annulus (9), tubule seal ring (11) is formed, bassoon nut (1) is threaded with bassoon threaded connector (2), the endoporus of bassoon threaded connector (2) is a taper hole, the more than half annulus of taper (5) that two halves fix bassoon is housed in its taper hole, one step hole (6) is arranged in the more than half annulus of taper (5), bassoon seal ring (7) is housed in this step hole (6), between the end face of bassoon nut (1) and the more than half annulus of taper (5), fix the T type cover (8) that is threaded is arranged, tubule nut (3) cover (8) that is threaded with the T type is threaded, the boss of little tubular union (4) is contained in tubule nut (3) and is threaded between the cover (8) with the T type, the endoporus of little tubular union (4) is a taper hole, the taper smaller part annulus (9) that two halves fix tubule is housed in its taper hole, one larger-diameter boss hole (10) is arranged in taper smaller part annulus (9), tubule seal ring (11) is housed in this boss hole (10); In order to use easy to adjust and to strengthen sealing effect, the end face of the more than half annulus of taper (5) is threaded the end face of cover (8) with the T type between, can fill up one deck large washer (12), between the T type is threaded the end face of the other end of cover (8) and taper smaller part annulus (9), also can fill up one deck small washer (13).
Owing to adopted technique scheme, the utility model is compared with existing pipe coupling, has the advantage that need not make screw thread on connected pipeline.During use, earlier large-diameter pipeline is injected in the bassoon seal ring (7), small diameter pipeline is injected in the tubule seal ring (11), tighten bassoon nut (1) and tubule nut (3), the taper hole that can be by bassoon threaded connector (2) and the taper hole of little tubular union (4) make more than half annulus of taper (5) and tapered smaller part annulus (9) that connected pipe is held tightly and link together.Because the utility model need not make screw thread on connected pipe, therefore construct very convenient, save time, laborsaving.
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the structural representation of the more than half annulus of the utility model taper;
Accompanying drawing 3 is the structural representation of the utility model taper smaller part annulus.
Embodiment of the present utility model: bassoon nut (1), bassoon threaded connector (2), tubule nut (3), little tubular union (4), the more than half annulus of taper (5), the T type cover (8) that is threaded, taper smaller part annulus (9) all can adopt cast iron or the higher metallic material of other intensity to make, bassoon nut (1) is threaded with bassoon threaded connector (2), the endoporus of bassoon threaded connector (2) is made as taper hole, in its taper hole, load onto the more than half annulus of taper (5) that two halves can fix connected large pipeline, the more than half annulus of taper (5) outer surface tapering is made into the same with the internal taper hole tapering of bassoon threaded connector (2), in the more than half annulus of taper (5), make the bigger step hole (6) of a diameter, in this step hole (6), load onto bassoon seal ring (7), the length of bassoon seal ring (7) is identical with step hole (6), between the end face of bassoon nut (1) and the more than half annulus of taper (5), fix and go up the T type cover (8) that is threaded, tubule nut (3) cover (8) that is threaded with the T type is threaded, the boss of little tubular union (4) is contained in tubule nut (3) to be threaded between the cover (8) with the T type, the endoporus of little tubular union (4) is made as taper hole, in its taper hole, load onto the taper smaller part annulus (9) that two halves can fix connected small pipeline, it is the same with the taper hole tapering of little tubular union (4) that the outer surface tapering of this taper smaller part annulus (9) is made into, in taper smaller part annulus (9), produce a larger-diameter boss hole (10), in this boss hole (10), load onto the tubule seal ring and (11); For easy to adjust and strengthen the sealing effect of pipe coupling in use, the end face of the more than half annulus of taper (5) is threaded the end face of cover (8) with the T type between, can fill up one deck large washer (12), between the T type is threaded the end face of the other end of cover (8) and taper smaller part annulus (9), also can fill up one deck small washer (13).
