Abstract
The utility model discloses a kind of high-precision rotary seal nipples, including pipeline, mechanical seal sleeve, flange and gland；The mechanical seal axle is sheathed on inside the connector of pipeline；The flange protrudes into the connector of pipeline, and is connected by gland with mechanical seal sleeve；Bearing is equipped between the connector inner wall and flange outer wall of the pipeline, the bearing uses NSK deep groove ball bearing to improve its load-carrying ability.Solve the problems, such as that traditional nitrile rubber sealing ring is easy season cracking；Unstable, the weaker problem of stress is rotated when solving the work of rotary joint caused by traditional single roller bearing, extends service life.
Description
Technical field
The utility model relates to seal for pipe joints technical field, especially a kind of high-precision rotary seal nipple.
Background technique
Rotation seal joint is generally used for the components being sealed when transmitting the liquid such as oil, water to pipe joint.
Traditional rotation seal joint uses nitrile rubber sealing ring, is easy season cracking, sealing ring is made to fail, from
And it leaks；General rotation seal joint uses single roller bearing simultaneously, rotates not when rotary joint being caused to work
Steadily, stress is weaker, influences the leakproofness of rotary joint, and service life shortens.
Utility model content
For various deficiencies existing in the prior art, the purpose of the utility model is to provide a kind of sealings of high-precision rotary
Connector, can be with the problems in effective solution background technique.
A kind of high-precision rotary seal nipple of the utility model, including pipeline, mechanical seal sleeve, flange and pressure
Lid；The mechanical seal axle is sheathed on inside the connector of pipeline；The flange protrudes into the connector of pipeline, and passes through gland
It is connected with mechanical seal sleeve；Bearing is equipped between the connector inner wall and flange outer wall of the pipeline, the bearing uses
NSK deep groove ball bearing is to improve its load-carrying ability.The rotation that the high-precision rotary seal nipple can be used for mechanical equipment simultaneously is close
At envelope.
Preferably, the high-precision rotary seal nipple further includes auxiliary seal ring, and the auxiliary seal ring is set to pipeline
Connector inner wall and mechanical seal sleeve outer wall between.
Preferably, the mechanical seal sleeve selects 316L stainless steel.
Preferably, the gland selects 316L stainless steel.
Preferably, the auxiliary seal ring selects fluorubber.
The utility model has the beneficial effects that by the way that the mechanical seal sleeve inside pipe joint is arranged in and passes through gland
The flange being connected with mechanical seal sleeve solves the problems, such as that traditional nitrile rubber sealing ring is easy season cracking；Pass through setting
NSK deep groove ball bearing between the connector inner wall and flange outer wall of pipeline, solves caused by traditional single roller bearing
Rotary joint rotates unstable, stress weaker problem when working, extend service life.
Detailed description of the invention
It, below will be right in order to illustrate more clearly of specific embodiment of the present invention or technical solution in the prior art
Specific embodiment or attached drawing needed to be used in the description of the prior art are briefly described.In attached drawing, each element or part

Novel protection scope.
As shown in Figure 1-3, a kind of specific embodiment of the utility model proposes a kind of high-precision rotary seal nipple, packet
Include pipeline 1, mechanical seal sleeve 2, flange 3 and gland 4；The mechanical seal sleeve 2 is set to inside the connector of pipeline 1；
The flange 3 protrudes into the connector of pipeline 1, and is connected by gland 4 with mechanical seal sleeve 2；The connection of the pipeline 1
Bearing 5 is equipped between head inner wall and 3 outer wall of flange, the bearing 5 uses NSK deep groove ball bearing to improve its load-carrying ability.It should
High-precision rotary seal nipple can be used at the rotary seal of mechanical equipment simultaneously.
As a specific embodiment, the high-precision rotary seal nipple further includes auxiliary seal ring 6, described auxiliary
Sealing ring 6 is helped to be set between 2 outer wall of connector inner wall and mechanical seal sleeve of pipeline 1.
As a specific embodiment, the mechanical seal sleeve 2 selects 316L stainless steel.
As a specific embodiment, the gland 4 selects 316L stainless steel.
As a specific embodiment, the auxiliary seal ring 6 selects fluorubber.
Finally, it should be noted that the above various embodiments is only to illustrate the technical solution of the utility model, rather than it is limited
System；Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should
Understand: it is still possible to modify the technical solutions described in the foregoing embodiments, or to some or all of
Technical characteristic is equivalently replaced；And these are modified or replaceed, it does not separate the essence of the corresponding technical solution, and this is practical new
The range of each embodiment technical solution of type, should all cover in the claim of the utility model and the range of specification.
