Abstract
The utility model discloses a pipe live knot without sealing ring, comprising a male part, a female part and a nut, which is characterized in that: the interface end of the female part is shown as a bell type conical surface and the interface end of the male part is shown as a spherical radius; the conical surfaces of the male part and the female part are closely matched (spherical radius sealing); a male thread is arranged at the interface end of the female part; after the male part is joined with the female part, a boss is arranged at the outer end of the joining part for the male part; the nut is screwed at the joint of the female part and the male part. The utility model has the advantages of no needing sealing for the sealing ring, simple structure, low cost and convenient connection.
Description
Technical field
The utility model relates to a kind of pipe movable joint.
Background technique
The pipe movable joint of prior art is that the interface end of parent part and component is straight mouthful, and component is connected with parent part must dose seal ring, and component is connected the back and uses nut sleeve on the outside thread of junction point with parent part.The shortcoming of this pipe movable joint is to increase seal ring, and cost is higher, and connects also inconvenient.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of no seal ring pipe movable joint, and simple in structure, cost is low, and is easy to connect.
No seal ring pipe movable joint of the present utility model, comprise component, parent part, nut, the interface end that it is characterized in that parent part is the conical surface of flare, the interface end of component is the mode of structure with the conical surface close fit of parent part, the interface end place of parent part has outside thread, component is with after parent part engages, and component has boss in the junction point outer end, and nut is threaded onto parent part and component junction point.
The interface end of the above component preferably is spherical radius, is into the spherical radius sealing configuration with the conical surface of parent part.
Parent part can be a straight tube as known technology still, also can be bend pipe.Specification, material are not limit.Material such as various non-ferrous metal and ferrous metal and various plastic material.Format diameter (external diameter of pipe of parent part and component) can be 3～3000 millimeters.
Pipe movable joint of the present utility model comprises various valve sealing elements equally.
Can be provided with two or more fixedly raised line on the internal diameter of component, be convenient to and being connected of other object (as pipe).
Parent part, component can be outer silks with the connecting end of pipe respectively, can be internal threads also, and Placement is flexible.
Advantage of the present utility model:
Do not need seal ring to seal between parent part and component, simple in structure, cost is low, makes between pipe or other object easy to connect.
Description of drawings
Fig. 1 is the structural representation of the utility model parent part;
Fig. 2 is the structural representation of the utility model component;
Fig. 3 is the left view of Fig. 1;
Fig. 4 is the nut structure schematic representation.
Among the figure: 1 parent part, 2 parent part interface end, 3 tubaeform conical surface 4 outside threads 5 components 6 boss 7 component interface end 8 nuts 9 are raised line fixedly
Embodiment
As Fig. 1, be straight tube parent part 1 structure, parent part interface end 2 flare conical surfaces 3.Component interface end 7 is spherical radius, matches into spherical radius sealing configuration mode with parent part interface end 2.During connection, component 5 is snapped in the parent part interface end 2 by its interface end 7, and parent part interface end place has outside thread 4, and nut is fixed on outside thread and boss 6 places (screw-internal thread fit of outside thread, boss and nut), and parent part and component are fixed together.On the component internal diameter two fixedly raised line 9 be convenient to and being connected of other pipe fitting.
When parent part was bend pipe, also just interface end engages with component, and was still as described above.
Claims (6)
1, no seal ring pipe movable joint, comprise component, parent part, nut, the interface end that it is characterized in that parent part is the conical surface of flare, the interface end of component is the mode of structure with the conical surface close fit of parent part, the interface end place of parent part has outside thread, component is with after parent part engages, and component has boss in the junction point outer end, and nut is threaded onto parent part and component junction point.
2, pipe movable joint according to claim 1 is characterized in that the interface end of component is spherical radius, becomes the spherical radius sealing configuration with the conical surface of parent part.
