Abstract
The utility model discloses a filament winding epoxy FRP cable duct tube, containing a tube shaft and a tube fitting. The inner wall of the tube fitting is divided into a straight section and a contraction section; the inner wall of the straight section is straight and the inner wall of the contraction section shows gradually contracted shape; a seal ring is sleeved at the mouth of the tube. The joint of the utility model is characterized by good sealing performance and no water leakage, therefore, the utility model can be applied as duct tube for cable and can effectively guarantee the safety of the cable wire and the free flow of electric line.
Description
Technical field
The utility model relates to a kind of pipe fitting, and specifically a kind of fiber twines the fiber glass epoxy cable duct tube.
Background technology
Existing cable conduit, the interface of conduit and conduit has the gap more, when running into water, water can be invaded catheter interior along the gap, has in catheter interior under the situation of water existence, is easy to cause wire short-circuiting, when serious, the meeting breaking out of fire is so now use the fail safe of this conduit relatively poor.
Summary of the invention
The technical problems to be solved in the utility model is at above-mentioned deficiency, designs a kind of fiber and twines the fiber glass epoxy cable duct tube.
Embodiment of the present utility model is: it comprises pipe shaft and tube head, and the inwall of tube head is divided into flat segments and contraction section, and the inwall at flat segments place is flat, and it is contraction-like gradually that the inwall at contraction section place is, and the place is with seal washer at the mouth of pipe.
The utlity model has joint good airproof performance, impermeable advantage, thereby it is as the cable conduit, can effectively guarantees the safety of cable, guarantee the unimpeded of supply line.

Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in the figure, comprise pipe shaft 1 and tube head 2, the inwall of tube head 2 is divided into flat segments and contraction section, and the inwall at flat segments place is flat, and it is contraction-like gradually that the inwall at contraction section place is, and is with seal washer 9 at mouth of pipe place.
Flat segments comprises big flat segments 7 and little flat segments 5, contraction section 6 and after-contraction section 4 before contraction section comprises; Big flat segments 7 is positioned at the mouth of pipe, is preceding contraction section 6 between big flat segments 7 and the little flat segments 5, and after-contraction section 4 is between little flat segments 5 and pipe shaft inner wall section 3.The bore at big flat segments 7 places is greater than the bore at little flat segments 5 places.Before the bore of contraction section 6, from its with the joint of big flat segments 7 to the joint of little flat segments 5, dwindle gradually.The bore of after-contraction section 4, the joint from the joint of itself and little flat segments 5 to pipe shaft inner wall section 3 dwindles gradually.
Seal washer 9 is a flange formula seal washer, and a circle flange 10 is arranged on the flange formula seal washer, and its inner surface has projection circle line 8, and flange 9 turns over and is buckled in the tube head port.
Seal washer 9 also can be used the combined labyrinth and carbon gland packing ring, and this combined type packing ring comprises packing ring body 11 and guide collar 13, and packing ring body 11 1 ends have wedge mouth 15, and the inner surface of packing ring body 11 has projection circle line 12.Guide collar 13 1 ends have the wedge head 14 that is complementary with wedge mouth 15.Packing ring body 11 is filled in tube head port inboard, and guide collar 13 is buckled in the wedge mouth 15 by wedge head 14 covers.
