Abstract
This application discloses a kind of pipe joints, including：First sleeve, for accommodating flexible pipe, first sleeve includes first end and second end；Second sleeve, for accommodating the flexible pipe, the second sleeve includes first end and second end, wherein the internal diameter of the first end of the second sleeve is less than the internal diameter of the second end of the second sleeve, and the second end of the second sleeve connects the first end of first sleeve；3rd sleeve, for accommodating the flexible pipe, the 3rd sleeve connects the first end of the second sleeve.The pipe joint of the application need not be inserted into flexible pipe due to being arranged in the outside of flexible pipe and transmit internal diameter to change.Simultaneously as the both ends diameter of second sleeve is different, therefore when flexible pipe is placed on inside connector, one end small positioned at second sleeve diameter can block flexible pipe, make to be relatively fixed between flexible pipe and connector.
Description
Technical field
This application involves connectors, more particularly to a kind of pipe joint.
Background technology
The joint connection manner of high pressure flexible tube uses buckle press joint mode at present, connector by core pipe, be sleeved on the set of outer wall
Cylinder and screw nut composition.Core pipe is inserted into flexible tube, then sleeve is sleeved on to the outside of flexible pipe, finally by spiral shell
Line nut fixes core pipe and sleeve, to clamp flexible pipe.
However this connection type has the disadvantage that：
1. can not achieve equal bores transmission.Since core pipe is inserted into flexible pipe, the transition from flexible pipe to core pipe
Internal diameter can be caused to become smaller.Thus turbulent flow is generated, causes stress fluctuation and pipe vibration, joint area easy tos produce shear stress and makes
At fatigue along bad.In addition, the unexpected reduction because transmitting bore, it is more serious to be easy to cause wax deposition phenomenon.
2. because core pipe is mechanically inserted flexible inside pipe wall, pipeline connection, meeting are realized by the contraction elasticity of flexible pipe
Cause the inner wall mechanical failure of flexible pipe.

The outer wall of interconnecting piece is bonded with the inner wall of first sleeve.
Optionally, the flexible pipe is polythene material.
The pipe joint of the application need not be inserted into flexible pipe due to being arranged in the outside of flexible pipe to change
Transmit internal diameter.Simultaneously as the both ends diameter of second sleeve is different, therefore when flexible pipe is placed on inside connector, it is located at the
The small one end of two sleeve diameters can block flexible pipe, make to be relatively fixed between flexible pipe and connector.
Further, the pipe joint of the application of the application, will not due to that need not be inserted into flexible tube firmly
Destroy the inner wall of flexible pipe.
According to the accompanying drawings to the detailed description of the specific embodiment of the application, those skilled in the art will be more
Above-mentioned and other purposes, the advantages and features of the application are illustrated.
Description of the drawings
Some specific embodiments of the application are described in detail by way of example rather than limitation with reference to the accompanying drawings hereinafter.
Identical reference numeral denotes same or similar component or part in attached drawing.It should be appreciated by those skilled in the art that these
What attached drawing was not necessarily drawn to scale.In attached drawing：
Fig. 1 is the schematic diagram according to the pipe joint of the application one embodiment；
Fig. 2 is the schematic diagram according to the pipe joint of the application one embodiment；
Fig. 3 is the diagrammatic cross-section according to the pipe joint of the application one embodiment.
Specific implementation mode
Fig. 1-Fig. 3 is please referred to, in one embodiment of the application, pipe joint includes：First sleeve 1, second sleeve 2 and
Three sleeves 3.Wherein the first sleeve 1 includes first end 11 and second end 12 for accommodating flexible pipe, the first sleeve 1.Second sleeve 2
For accommodating flexible pipe, second sleeve 2 includes first end 21 and second end 22, the wherein internal diameter of the first end 21 of second sleeve 2
Less than the internal diameter of the second end 22 of second sleeve, and the second end 22 of second sleeve 2 connects the first end 11 of the first sleeve 1.The
Three sleeves 3 connect the first end 21 of second sleeve 2 for accommodating flexible pipe, 3rd sleeve 3.
In use, flexible hose is placed in the first sleeve 1, second sleeve 2 and the 3rd sleeve 3 of connector.Pass through
The first end of two sleeves blocks flexible pipe, makes to be relatively fixed between flexible pipe and connector.
In one embodiment of the application, second sleeve 2 is frustum shape.
In one embodiment of the application, pipe joint further includes：Annular groove 4 and lip ring 5.Its annular recess
