Description
Technical field
The utility model is a kind of ring type press briquet ting pipe joint, is applicable to the pipe joint on aviation pipeline road, belongs to aviation pipeline road field.
Background technique
Pipeline road in aviation is higher for the stability requirement of pipeline, because the transport pipe material of aviation and performance mostly adopt General Construction, all can meet the requirement of pipeline road, so pipe joint on pipeline road has just become the key link determining pipeline road performance, the sealing of pipe joint, antidetonation, pull resistance and high voltage performance have been the important indicators of beam pipe joint.
Such as CN1321233A disclosed " radial conduit coupling system and method ", provides a kind of radial passage joint.This pipe coupling can comprise one first tubular connection, and it has an external diameter, an internal diameter and the first and second ends.First end is suitable for receiving one first pipeline.The second end can comprise at least one and be configured to the snap close bead matched with at least one shaping depression of the component of a pipe-line system.This snap close bead can extend out from least one prominent the locking of the second end being arranged on the first link.In one embodiment, can be extended out a projection from internal diameter, first end and the second end roughly separate by it.This projection can have the internal diameter that corresponds essentially to the first internal diameter of the pipeline.Can arrange a sealing surfaces between projection and snap close bead, sealing surface can be configured to matches with the second sealing surfaces of one second link and basically form Fluid Sealing between the first link and the second link.
What this pipe coupling adopted is connect in outside threaded passage, after connecting there is gap or breach at jointing in the internal diameter of pipeline road, the existence of these gaps or breach can bring impact to the oil circuit transmission in pipeline road, reduces oil circuit transmission speed, increases transmission pressure.
For another example CN101680590A disclosed " for detecting the method and system be connected with the dry fit in closed conduit assembly ", institute provides a kind of preferred adapter assembly, and this adapter assembly can not connect with a kind of dry fit connection and the one in being not exclusively tightly connected and keep hydrodynamic pressure.This adapter assembly comprises a kind of joiner for identified leakage.Or rather, this joiner comprises the wall section of a tubulose substantially, the passageway that this wall section has an outer surface, an internal surface and settles along this one of internal surface and outer surface.This passageway has one first structure and one second structure, this first is configured to carry a kind of fluid between the inside of this pipe-line system and the outside of a pipe-line system, and this second structure is used for preventing from carrying fluid between the inside and outside of this pipe-line system.When having the sealing material of minimum flow, this passageway can be preferably this second structure from this first tectonic transition further.
This adapter assembly can not make the tubing internal diameter at two ends continuous when in use, and after installation, between two line ports, still there is certain depressed area, this depression also can cause the generation of turbulent flow, reduces the oil transportation speed of pipeline road inside.
So based on foregoing, design a kind of sealing configuration good, mouth of pipe docking location does not exist gap, making the connecting duct that the resistance of tube wall convection cell reduces, is the technical problems to be solved in the utility model.
Model utility content
The purpose of this utility model is to provide a kind of ring type press briquet ting pipe joint, adopts the mode of the molded sealing of external rings, makes the better tightness of connecting pipe structure, extends the working life of connecting duct.
The purpose of this utility model carrys out specific implementation by the following technical programs:
A kind of ring type press briquet ting pipe joint, be applied to the first connecting tube of docking and the connection part of the second connecting tube mutually, comprise integrated body, body cylindrically, the middle part of body is provided with circular protrusion, and the internal diameter of circular protrusion and the first connecting tube, the internal diameter of the second connecting tube is equal, the height of circular protrusion and the first connecting tube, the wall thickness of the second connecting tube is equal, at body internal diameter and first connecting tube of circular protrusion both sides, the external diameter of the second connecting tube is equal, and in the inner body wall of the both sides of circular protrusion, be respectively equipped with 3-5 annular recess, the spacing of two adjacent annular recess is 1-3mm.
The degree of depth of described annular recess is 1-2mm.
The position, base angle of described annular recess arranges destressing arc, concentrates to reduce stress.
The outside caliber of body is identical, is cylinder-like structure, and the identical outside of body that makes of outside caliber is easy to processing, can ensure the attractive in appearance and smooth of external structure simultaneously, is convenient to install, use and clear up.
When using, first the first connecting tube, the second connecting tube are plugged on the two ends of pipe joint body, and port part and the circular protrusion of the first connecting tube, the second connecting tube abut against, now the position of the first connecting tube, the second connecting tube, pipe joint body is interfixed, then utilize ring to be installed with for carrying out the processing of ring pressure to the outside of pipe joint body, the inwall between the annular recess of connecting tube body interior is compressed with the first connecting tube, the second connecting tube and is connected and seals.
A kind of ring type press briquet ting pipe joint described in the utility model, adopts the mode of the molded sealing of external rings, makes the better tightness of connecting pipe structure, extends the working life of connecting duct; The annular projection that body interior is arranged is equal with the internal diameter of the connecting tube at two ends, makes body after being connected with connecting tube, can not there is breach or gap between the inside of body and connecting tube, unimpeded through body of guarantee fluid.
