Abstract
The utility model provides a double-seal cable sealing joint which comprises a two-way external thread joint, a nut and a one-way external thread joint; grooves are arranged at two ends of the nut respectively; the axial section of the side wall of the nut is I-shaped; threads are arranged in the grooves; and the two-way external thread joint and the one-way external thread joint are inserted in the grooves respectively and are in threaded connection with the nut. The double-seal cable sealing joint has the beneficial effects that two-way sealing ensures better leak tightness of a cable and double-layer threads in the nut lead connection to be tighter, and has the advantages of simple structure, convenience in maintenance, low machining cost, high production efficiency, good sealing effect and the like.
Description
Technical field
The utility model relates to a kind of cable sealed joint, especially relates to a kind of double containment cable sealed joint.
Background technology
The method of the anti-explosion cable seal nipple clamping cables in existing technology; Be to adorn rubber seal between hex nut and hex union body; Tighten through hex nut and hex union body and to make rubber gasket distortion clamping cables; Though this method meets requirement of explosion proof, have that clamping force is big inadequately, sealing is good inadequately, receive influence and the loose cables of external pull and being connected of equipment easily, thereby reduced explosion-proof reliability.
Summary of the invention
The problem that the utility model will solve provides a kind of double containment cable sealed joint, has double sealing structure, connects stable more, good sealing effect, especially is fit to industries such as oil, chemical industry, oil, chemical industry, metallurgy, electric power, pharmacy and cement.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of double containment cable sealed joint; Comprise two-way male connection, nut and unidirectional male connection, said nut two ends all are provided with groove, and the sidewall axial cross section of said nut is I-shaped; Be provided with screw thread in the said groove, said two-way male connection is inserted in the groove with unidirectional male connection and is connected with said nut thread.
Also comprise the seal washer that is arranged in the groove.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme; The shaft section that the nut two ends are respectively equipped with a circular groove and nut is I-shaped; Said two-way male connection one end screws in nut, and the male end of said individual event male connection screws in nut.Also comprise the seal washer in the groove.Two way seal makes that Seal of Cables property is better, double-deck screw thread makes connection tightr in the nut; Have advantages such as simple in structure, easy to maintenance, processing cost is low, production efficiency is high, good sealing effect.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure:
1, two-way male connection 2, nut 3, unidirectional male connection
4, groove 5, O-ring seal
Embodiment
As shown in Figure 1; The utility model provides a kind of double containment cable sealed joint; Comprise two-way male connection 1, nut 2 and unidirectional male connection 3, said nut 2 two ends all are provided with groove 4, and the sidewall axial cross section of said nut 2 is I-shaped; Be provided with screw thread in the said groove 4, said two-way male connection 1 is inserted in the groove 4 and with said nut 2 with unidirectional male connection 3 and is threaded.
Also comprise the seal washer 5 that is arranged in the groove 4.
The course of work of this instance: said two-way male connection 1, nut 2 are connected with unidirectional male connection 3 successively.Nut 2 two ends are respectively equipped with a circular groove 4 and are used to put seal washer 5.The diameter at said two-way male connection 1 two ends is different.During work, in the groove 4 of the approaching end of nut 2 and two-way male connection 1, place seal washer 5, the butt end of two-way male connection 1 screwed in the groove 4 of nut 2, double-deck screw thread make connect more firm; The butt end of two-way male connection 1 compresses seal washer 5, plays sealing function.The thin end of two-way male connection 1 is used to connect other parts away from nut 2.Unidirectional male connection (3) screws into nut 2 and compresses seal washer 5, and internal thread one side is used to connect other parts.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
Claims (2)
