The present invention relates to a kind of stainless steel joint for pipeline, including joint body, joint body includes interior joint, reducing joint and external connector, joint and external connector in reducing joint connection, inside internal thread is provided with inside joint, external screw thread is provided with outside external connector, is provided with interior buffer gasket between the internal and internal thread of reducing joint, be provided with outer buffer gasket between the outside and external screw thread of reducing joint.The present invention has following advantages compared with prior art：Overall structure is simple, and manufacture craft is easy, reduces the limitation of connection, extends service life, also saves cost, and connection is reliable, the effect for fundamentally preventing stainless steel tube from departing from from socket component.
Description
Technical field
The present invention relates to a kind of stainless steel joint for pipeline, belongs to steel pipe technical field.
Background technology
Stainless steel tube is a kind of hollow strip circular steel, is widely used mainly in oil, change
The industrial transportation pipe lines such as work, medical treatment, food, light industry, machinery instrument and frame for movement portion
Part etc..In addition, when bending, torsional strength are identical, lighter in weight, so also extensively use
In manufacture machine components and engineering structure.In this kind of conveyance conduit and frame for movement, stainless
Coupling is the requisite part of each section of stainless steel tube of connection, of the prior art stainless
The service life of coupling is short, complex structure, and connection effect is not desired to reason.
Therefore, it should a kind of new technical scheme is provided and is solved the above problems.
Content of the invention
The present invention provides a kind of stainless steel joint for pipeline.
For reaching above-mentioned purpose, the technical solution used in the present invention is：
A kind of stainless steel joint for pipeline, including joint body, joint body include interior joint,
Reducing joint and external connector, joint and external connector in reducing joint connection, inside connect
Head is internal to be provided with internal thread, is provided with external screw thread outside external connector, inside reducing joint with interior
Interior buffer gasket is provided between screw thread, is provided with outer buffering between the outside and external screw thread of reducing joint
Packing ring.
The relevant content of technique scheme is explained as follows：
In technique scheme, the diameter of external connector is less than the diameter of interior joint.
Further technical scheme, internal thread and external screw thread are on same vertical direction.
Preferably, inside joint and external connector port are respectively equipped with seal washer.
As technique scheme is used, the present invention has following excellent compared with prior art
Point：
Overall structure is simple, and manufacture craft is easy, reduces the limitation of connection, extends
Service life, also saves cost, and connection is reliable, fundamentally prevents stainless steel tube from holding
The effect that plug-in unit departs from.

Specific embodiment
Below in conjunction with the accompanying drawings and embodiment the invention will be further described：
Embodiment one：
As shown in figure 1, a kind of stainless steel joint for pipeline of the present invention, including joint body, connects
Head body include in joint 1, reducing joint 2 and external connector 3, external connector 3 straight
Less than the diameter of interior joint 1, reducing joint 2 connects interior joint 1 and external connector 3 in footpath,
Inside internal thread 4 is provided with inside joint 1, be provided with external screw thread 5, interior spiral shell outside external connector 3
Line 4 and external screw thread 5 facilitate the making of body, reducing joint 2 on same vertical direction
Interior buffer gasket 6,2 outside and external screw thread 5 of reducing joint is provided between internal and internal thread 4
Between be provided with outer buffer gasket 7, inside joint 1 and 3 port of external connector are respectively equipped with sealing
Packing ring 8, increases air-tightness, and overall structure is simple, and manufacture craft is easy, reduces connection
Limitation, extends service life, also saves cost, and connection is reliable, fundamentally prevents
The effect that only stainless steel tube departs from from socket component.
Above-described embodiment technology design only to illustrate the invention and feature, its object is to allow ripe
The personage for knowing technique will appreciate that present disclosure and implement according to this, can not be limited with this
Protection scope of the present invention processed.All equivalence changes that is made according to spirit of the invention are repaiied
Decorations, should all be included within the scope of the present invention.
