Abstract
A universal movable joint is composed of centering joint, movable joint, sealing washer and connecting nut. The centering joint of the universal movable joint has an included angle alpha between the normal of the movable joint and the axes thereof1Or alpha2. The pipeline direction can be changed according to different angles. The contact position of the centering joint and the loose joint is adjusted. Causing the angle between their axes to change. And the pipeline connection in different directions is realized. Thereby saving a large amount of manual pipe bending work.
The universal movable joint has novel and simple structure. The preparation is convenient. Is suitable for connecting industrial water and domestic water pipelines and has practical and popularization values.
Description
A kind of universal union that is applicable to that industry and domestic water pipeline connect.Belong to the F16L15/00 class.
Before these innovation and creation.Be used for the union that industrial water pipeline and domestic water pipeline connect.Its structure and profile differ from one another.Applicability is also very wide; But deficiency is all more complicated of structure.It is little convenient to make maintenance.
The purpose of this utility model is to provide a kind of new-type practical again universal union for the user.The maximum characteristics of this universal union be its centering connect and the heart of living to connect contacted surface normal be α with the angle between their axis
1With α
2Duct orientation according to different occasions.A selected cover α
1(or α
2) the universal union of a fixed value arranged.Connect the contact position that (1) and the heart of living connect (4) by regulating centering.The pipeline that just can adapt to different direction connects.
Below in conjunction with accompanying drawing the utility model is done detailed explanation.
Accompanying drawing 1 is the structure cross-sectional schematic of universal union.
Accompanying drawing 2 connects the cross-sectional schematic of (1) for centering.
Accompanying drawing 3 connects the cross-sectional schematic of (4) for the heart of living.
Accompanying drawing also is embodiment of the present utility model.
Adopt general process for machining to make this universal union.
As shown in the figure.When making the universal union of a certain cover.Connect in centering and to produce one on (1) and protrude partly (5).Connect at the heart of living and to produce a recessed part (6) on (4).The diameter that protrudes part (5) is littler 1.0～5.0 millimeters than the diameter of recessed part (6); The degree of depth of the recessed part of aspect ratio (6) of protrusion part (5) is big 0.5～3.0 millimeter.It is EF that centering connects the surface of contact that (1) and the work heart connect (4).Reach organic and cooperate for centering being connect connecing with the work heart.The normal of the surface of contact EF that must making during making feels relieved connects (1) and the angle α between its axis
1The heart that equals to live meets the angle α between the normal of surface of contact EF of (4)
2Can make the α that sends as an envoy to
1(or α
2) series product that between 0～45 °, change.
The protrusion part (5) that seal washer (3) places centering to connect (1) connects between the recessed part (6) of (4) with the heart of living, and its material is the micarta of waterproof.
During use.Earlier selected α
1(or α
2) connect at the heart universal alive of a certain angle.Size according to domestic water pipeline or the required trend of industrial water pipeline or institute's bending angle is selected.
Regulate centering simultaneously and connect the contact position that (1) and the heart of living connect (4).I.e. centering connects (1) and protrudes partly (5) and can freely rotate in the heart of living connects the recessed part (6) of (4).Along with connecing (1), centering connects the different of (4) contact position with the heart of living.Angle between their axis is also along with changing.When changing to desired location.Being tightened against the heart alive with coupling nut (2) connects on (4).Centering is connect (1) and contact position that the heart of living connects (4) is fixed up.Just can connect (1) in centering this moment or external pipe is located at (or going out) mouth of a river of advancing that the heart of living connects (4).Realize the different trends of pipeline.
The profile of coupling nut is circle, square, hexagon or octagon etc.
The most preferred embodiment of this case is α
1(or α
2) at 0～30 °, then the angle that centering connects (1) and the heart of living connects between (4) axis can change between 0～60 °, the profile of coupling nut (2) is a hexagon.
Claims (8)
1, a kind of universal union, by centering connect (1), the heart of living connects (4), coupling nut (2) and seal washer (3) and forms, it is characterized in that centering connects (1) part of protrusion (5) is arranged, the heart of living connects recessed part (6) on (4), and coupling nut (2) is twisted in the heart of living and connect on (4).
2, universal union according to claim 1 is characterized in that centering connects (1) and connects a surface of contact EF is arranged between (4) with the work heart.
3, universal union according to claim 1 and 2 is characterized in that centering meets the normal of surface of contact of (1) and the angle α between its axis
1The heart that equals to live meets the normal of surface of contact of (4) and the angle α between its axis
2
4, according to the described universal union of claim 1, it is characterized in that α
1(or α
2) can between 0～45 °, change.
5, universal union according to claim 1, its feature connect (1) in centering the protrusion partly diameter of (5) is littler 1.0～5.0 millimeters than the diameter that the heart alive connects the recessed part (6) on (4).
6, partly live universal according to claim 1 or 5 union, its feature connect (1) in centering protrusion to connect the degree of depth of recessed part (6) of (4) big 0.5～3.0 millimeter for the heart by the aspect ratio of (5).
7, universal union according to claim 1 is characterized in that seal ring (3) places centering to connect (1) protrusion part (5) and connects between the recessed part (6) of (4) with the heart of living.
8, universal union according to claim 1, the profile that it is characterized in that coupling nut (2) is circle, square, hexagon or octagon etc.
