Abstract
The invention relates to a connector sealing device which comprises an internal threaded connector, an external threaded connector and a threaded bushing. The internal surface and the external surface of the threaded bushing are provided with threads. The external threads of the threaded bushing are matched with the internal threaded connector. The internal threads of the threaded bushing are matched with the external threaded connector. The threads, matched with the internal threaded connector, of the threaded bushing are fine threads, and thread seal tape is arranged between the threads, matched with the external threaded connector, of the threaded bushing. Due to the fact that the threaded bushing is adopted between the external threaded connector and the internal threaded connector and the fin threads on the threaded bushing are matched with the external threaded connector, the connector sealing performance is improved, and the internal threaded connector is effectively protected.
Description
Technical field
The present invention relates to a kind of interface sealing device.
Background technology
For the sealed interface that seal request is tighter, as in specific type of electric machine, bosh is provided with between electric machine stand inwall and outer wall, the sealing of the interface that tank is connected with outside is generally and is wound around raw material band on screw thread, but, when carrying out vacuum pressure impregnation together with support after stator built-in line, can there is impregnating varnish enters in the bosh of support, be stranded in tank after dry, the impregnating varnish entered particularly cannot be removed for spirality tank, when motor is run, cooling water can not enter support and circulates, motor does not reach cooling effect, and the helicitic texture that bosh is connected with outside, tearing open repeatedly, very easily impaired in process of assembling.
Summary of the invention
The object of the invention is to overcome above defect, provide that a kind of not damage interface thread, sealing reliable and can be adapted to the interface sealing device of vacuum pressure environment.
Technical scheme of the present invention is: a kind of interface sealing device, it comprises internal thread interface, external screw joint, also comprise thread bush, the surfaces externally and internally of thread bush is equipped with screw thread, external screw thread and the internal thread interface of thread bush match, internal thread and the external screw joint of thread bush match, and the screw thread that described thread bush and external screw joint match is fine thread, are provided with raw material band between the screw thread that thread bush and external screw joint match.
In order to improve sealing effectiveness further, also comprise O type circle, described O type circle is located between the end contact face of external screw joint and thread bush.
In order to improve the life-span of thread bush, the hardness of described thread bush material and intensity are higher than the hardness of internal thread interface material and intensity.
In order to improve sealing, also comprise alignment pin, described alignment pin is located between the end contact face of internal thread interface and thread bush.
In order to improve sealing, the connecting end surface cylindrical of described thread bush and internal thread interface is provided with symmetrical chamfering, and the chamfering of the connecting end surface of thread bush and internal thread interface forms a V-ring groove, is provided with fluid sealant in described V-ring groove.
Advantageous Effects of the present invention have employed thread bush between external screw joint and internal thread interface, and the hardness of thread bush material and intensity are higher than the hardness of internal thread interface material and intensity, effectively protect internal thread interface; Symmetrical chamfering is provided with at the connecting end surface cylindrical of thread bush and internal thread interface, fluid sealant is scribbled in the V-ring groove formed, and the end contact face of internal thread and thread bush is fixed with alignment pin, thread bush and external screw joint are fine thread, O type circle is provided with between external screw joint and the end contact face of thread bush, improve the sealing property of interface entirety, effectively prevent impregnating varnish from entering.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
