Abstract
This invention discloses one wire joint sealing device for sea use, which comprises sealing tube, tamper and press cover, wherein, the press cover is set with inner screw beam; the both ends of sealing tube inner circle is set with match able inner tamper surface to the tamper joint; the sealing tube two ends outside circle is set with outside screw and the tamper joint is pressed to the inner tamper through press cover; the said tamper joint and presser cover are separately opened with match able holes with wire through the sealing tube.
Description
Technical field
The present invention relates to a kind of cable joint sealing apparatus with Yu Haiyang.
Background technology
When ocean platform is worked, can some devices be installed under the sea usually, this will inevitably relate to lead as power line or holding wire.And because the limited length of lead, need sometimes several leads are coupled together uses, so terminal will appear.If directly joint is exposed in the seawater, may cause short circuit on the one hand, the metal of Bao Luing can be subjected to the corrosion of seawater on the other hand.
Addressing this problem at present mainly is that adhesive plaster with waterproof is wrapped in the joint, although can play certain waterproof purpose, is immersed in the water for a long time and still comes off easily.
Summary of the invention
At the problem of above-mentioned existence, the object of the present invention is to provide a kind of cable joint sealing apparatus with Yu Haiyang, this device can improve sealing effectiveness greatly.
For achieving the above object, a kind of cable joint sealing apparatus with Yu Haiyang of the present invention comprises: sealed tube, cone wedge head and gland, gland is provided with internal thread, the two ends inner peripheral surface of sealed tube is provided with the inner conical surface that matches with described cone wedge head shapes, sealing pipe two ends outer circumference surface is provided with the external screw thread that the internal thread with described gland matches, the cone wedge head is pressed on the inner conical surface by gland, have the perforate suitable on described cone wedge head and the gland with diameter of wire, lead passes perforate, and the joint of described lead is positioned at sealed tube.
Further, described sealed tube is made by metal material, and described cone wedge head is made by elastomeric material.
Further, the position that is positioned at described terminal in described sealed tube also is filled with silica gel, leaves the gap between silica gel and the described cone wedge head.
The present invention can be sealed in the sealed tube joint of lead by sealed tube and cone wedge head are set well, particularly in the position at past more deep-sea, because the pressure of seawater is pressed in the sealed tube cone wedge first watch, thereby has guaranteed the sealing of lead.In addition, in sealed tube, insert suitable silica gel, more strengthened the sealing effectiveness of terminal.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1, the present invention includes: sealed tube 1, cone wedge head 6 and gland 3, gland 3 is provided with internal thread, the two ends inner peripheral surface of sealed tube 1 is provided with the inner conical surface that matches with cone wedge head 6 shapes, sealing pipe 1 two ends outer circumference surface is provided with the external screw thread that the internal thread with gland 3 matches, and cone wedge head 6 is pressed on the inner conical surface by gland 3, has on cone wedge head 6 and the gland 3 and the suitable perforate of lead 5 diameters, lead 5 passes perforate, and the joint 2 of lead 5 is positioned at sealed tube 1; Wherein, sealed tube 1 is made by metal material, preferably has decay resistance by stainless steel etc. and has preferably the metal material of toughness make, and cone wedge head 6 is made by elastomeric material, for example rubber etc.
In addition, the position that is positioned at terminal 2 in the sealed tube 1 also is filled with silica gel 4, leaves gap 7 between silica gel 4 and the cone wedge head 6, can further strengthen sealing effectiveness like this.
When the present invention is used Yu Haiyang, because seawater can apply a pressure to cone wedge head 6, therefore cone wedge head 6 more closely can be pressed against sealed tube 1 two ends, past more seabed then effect is good more, has therefore solved sealing problem well.
