Abstract
The utility model discloses an end sealing device for a cable through conduit, which comprises an annular jacket sleeved between a cable conduit and a cable, and a sealing sleeve arranged between the annular jacket and the cable. The sealing sleeve of a micropore structure is made of rubber material mixed with polyurethane material having hydrophilic groups. The inner surface of the cable conduit is provided with a groove. The outer surface of the annular jacket is also provided with a groove corresponding to the groove in the inner surface of the cable conduit. A complete sealing ring groove is formed by the groove in the inner surface of the cable conduit and the groove in the outer surface of the annular jacket. A sealing ring of a micropore structure and made of rubber material mixed with polyurethane material having hydrophilic groups is arranged in the sealing ring groove. The annular jacket is provided with a deflating valve and a suction nozzle. According to the technical scheme of the utility model, the device is used for sealing a cable through conduit and preventing water from leaking into the cable through conduit. Meanwhile, the sealing ring and the sealing sleeve can expand in size by 3-4 times when in contact with water. Therefore, the expansive force between the cable and the annular jacket, and the expansive force between the annular jacket and the cable conduit, are increased, so that the aim of preventing the water seepage is realized. Meanwhile, due to the arrangement of the suction nozzle and the deflating valve, the air pressure in the cable conduit and the outside air pressure are balanced.
Description
Technical field
The utility model belongs to sealing device, relates in particular to a kind of sealing device being applied in frp cable protective pipe.
Background technology
Electric power, communication cable, passing a bridge or when embedded underground, need to putting cable protection pipe, adopt metal pipe material in the past, and protection metal pipe quality is large, valency is high, not corrosion-resistant.In recent years; corrosion-resistant easy working glass fibre reinforced plastic protection starts extensive use; adopt fiberglass reinforced plastics material and distinctive socket fitting type structure conveniently, there is all-in-one-piece loud-speaker shape processed enlarging one end of every section of pipe, and the internal diameter of enlarging is greater than the external diameter of pipe and forms inner face.While connecting sealing, on a headgear of another section of a pipe, sealing ring inserts enlarging, until above-mentioned port.Existing sealing ring adopts flexible quality of rubber materials; its structure is that one end of rubber sleeve is connected with inside bulge loop; the outer wall of rubber sleeve has the spaced saw-tooth ring of all-in-one-piece backbone circle processed; sawtooth hypotenuse is positioned at bulge loop one side; the internal diameter of rubber sleeve is prior to the external diameter of glass fibre reinforced plastic protection, and the aperture of bulge loop is prior to the internal diameter of protection tube, puts the expansion product that insert protection tube after sealing ring; sawtooth pushes against with the inwall that expands product, and its pawl produces sealing and only pulls out effect.In this type of sealing ring construction, work efficiency is higher, also corrosion-resistant, but water permeability resistance can be poor.Also has the glass steel cable protection tube sealing device that a kind of water permeability resistance can be stronger; as Chinese utility model patent 02232219. 1; denomination of invention is " glass fiber reinforced plastics electric cable protective sleeve impervious packing ring "; the inside bulge loop that comprises pipe box and be connected with its one end; outer tube wall has the above saw-tooth ring of all-in-one-piece two circle processed; the remaining limit of sawtooth is positioned at bulge loop one side; sawtooth height lowers gradually to bulge loop aspect; wherein sealing ring is to mix and have hydrophilic radical and polyamine to waste in rubber, is microcellular structure.This utility model mixes and has hydrophilic radical in rubber; its group is being met after water and water molecules; volume increases 3-4 doubly; thereby the expansive force between sealing ring and protection tube is increased; reach the object that prevents infiltration; but after group and water, increase and easily cable protection pipe is burst too much with water molecules volume, so just do not have the object that prevents infiltration.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency a kind of cable pipe end sealing device is provided.
For achieving the above object, the utility model is by the following technical solutions:
A kind of cable pipe end sealing device, comprise the ring-type chuck being set between cable tube and cable, the Polyurethane and the structure that be provided with rubber between ring-type chuck and cable in, are mixed with hydrophilic radical are the sealing shrouds of micropore shape, be provided with groove at cable tube inner surface, on the ring-type chuck outer surface corresponding with cable tube inner surface recesses, groove is also set, the seal groove of the groove complete of the groove of cable tube inner surface and ring-type chuck outer surface, the sealing ring that is mixed with the Polyurethane of hydrophilic radical and structure in rubber and is micropore shape is arranged in seal groove, on ring-type chuck, be provided with a deflating valve and a suction nozzle.
Above-mentioned cable pipe end sealing device, at least two of described seal grooves.
Adopt above-mentioned technical characterictic, the utility model has following advantage: the utility model can hermetically-sealed cable poling, prevent infiltration, sealing shroud and sealing ring are met after water simultaneously, volume increases 3-4 doubly makes expansive force between cable and ring-type chuck and between ring-type chuck and cable tube increase, and reaches the object that prevents infiltration.The setting of suction nozzle and deflating valve can keep cable tube and ambient pressure balance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Embodiment
A kind of cable pipe end sealing device as depicted in figs. 1 and 2, comprise the ring-type chuck 8 being set between cable tube 5 and cable 6, the Polyurethane and the structure that be provided with rubber between ring-type chuck and cable 6 in, are mixed with hydrophilic radical are the sealing shrouds 3 of micropore shape, be provided with groove at cable tube 5 inner surfaces, on the ring-type chuck outer surface corresponding with cable tube inner surface recesses, groove is also set, the seal groove of the groove complete of the groove of cable tube inner surface and ring-type chuck outer surface, the sealing ring 4 that is mixed with the Polyurethane of hydrophilic radical and structure in rubber and is micropore shape is arranged in seal groove, on ring-type chuck, be provided with a deflating valve 2 and a suction nozzle 7.
Above-mentioned cable pipe end sealing device, at least two of described seal grooves.
