Description
Technical field
The utility model relates to a kind of pipe laying unit, the gas-flow closure bag that specifically adopts when installing cables and pipeline.
Background technology
Present cable carries out provided underground mostly, and the pipeline of the underground extending transversely of cable process stretches in cable shaft and continues; But at cable shaft borehole wall end, shutoff must be carried out in the space that stays between pipeline and cable, enters to stop sewage, avoids causing that cable is aging, and prevents muroid destruction cable, guarantees the normal operation of cable.Close measure is to adopt the cable pressurization sealing bag to carry out the shutoff sealing comparatively easily at present.
The structure of conventional cable pressurization sealing bag adopts aluminium plastic composite material as the sealing bag bag, is manufactured with the gas-filled tube of inflation use on bag, has also configured to be used for stopping up the self-healing packing material that small opening is used.During use first with sealing bag around being coated on the cable that is positioned at pipeline opening, then inflation makes the sealing bag expansion that the space between pipeline and cable is stopped up, extract at last gas-filled tube, utilize the self-healing packing material in sealing bag inner chamber to block the aperture that gas-filled tube stays, prevent that the internal gas in sealing bag from leaking.
The defective of said structure is: the performance of self-healing packing material shutoff small opening is limited, can't keep the expanded air pressure in sealing bag in long-time, and then affected plugging effect; And self-healing packing material and gas-filled tube can only disposablely use (can't reuse), and utilance is too low.In addition, the aluminium skin resists as the sealing bag bag fold limited in one's ability; Folding slightly several under, the fold position will form breach and cause gas leakage; Cause sealing bag to reuse.
The utility model content
The purpose of this utility model is the deficiency that overcomes in the above-mentioned background technology, and a kind of improvement of cable duct seal bag is provided, and this cable duct seal bag should have that gas be difficult for to leak, sealing characteristics is good, reusable characteristics.
The technical solution of the utility model is: cable duct seal bag, comprise that one has the strip bag of closed cavity, two side external surfaces of described bag are applying respectively the pitch adhesive tape that stretches along its length, one pneumatic element that is communicated with closed cavity also is housed on bag, it is characterized in that: described pneumatic element is valve cock; Described bag is flexible bag or plastic-aluminum combined bag.
The wall section bonding of the pedestal of described valve cock and bag is fixing.
The making material of described flexible bag is polyurethane coating cloth or PVC film or woven dacron or airtight cloth.
The outer surface of described bag one side is also being pasted two foam adhesive tape, and two foam adhesive tape are arranged in parallel and are positioned at separately the both sides of pitch adhesive tape.
Described pitch adhesive tape or foam adhesive tape extend to whole bag on the length direction of bag.
The beneficial effects of the utility model are: the utility model selects valve cock as pneumatic element, not only can guarantee sealing effectiveness, and can repeatedly fill, exit, and meets the reusable requirement of sealing bag; Select polyurethane (TUU) coated fabric, guaranteed that not only gas can not leak, and also can be not damaged in folding situation, be fit to the reusable requirement of sealing bag fully.The utility model can adapt to repeatedly, reusable reality needs, can significantly reduce use cost, has promotion prospect preferably.

Fig. 2 is plan structure schematic diagram of the present utility model.
Fig. 3 is backsight structural representation of the present utility model.
Fig. 4 is the A-A cross-sectional view in Fig. 2.
Embodiment
As shown in Figure 1, the main part of this cable duct seal bag is that length, the width of strip bag 1(bag all can be determined as required), this bag adopts flexible bag (nonmetallic materials) to make flexible bag, perhaps adopts aluminium plastic composite material to make plastic-aluminum combined bag; Flexible bag can adopt PVC film, woven dacron, airtight cloth to make, and as recommendation, (this coated fabric directly outsourcing obtains can to select polyurethane (TUU) coated fabric.
The bag that weldering forms through high frequency Hot has an inflatable closed cavity 2; Also be shaped with pneumatic element 3 on bag, make closed cavity be in communication with the outside.The preferred valve cock of described pneumatic element (disposing valve inside in valve cock) is the conventional components of buyable acquisition.As shown in Figure 4, be shaped with on the pedestal of valve cock (plastic base body) circumferential hoop around groove, bag wall section is shaped with an aperture that is complementary; After the aperture edge embeds groove, namely be connected as a single entity securely through high frequency Hot postwelding.Valve cock the position is set, can be as shown in the figure on the side of bag, also can at the central part of two side external surfaces of bag, determine according to user's needs.
The middle part of two side external surfaces of described bag is applying respectively the pitch adhesive tape 4 with water-proof function
(this pitch adhesive tape can keep good adhesive property in-30 ℃ of-250 ℃ of scopes), this pitch adhesive tape extends to whole bag along the length direction of bag, and the width of pitch adhesive tape can be 3-5cm usually; Wherein the outer surface of bag one side is also being pasted 5, two foam adhesive tape of two foam adhesive tape and is being arranged in parallel, and is positioned at separately the both sides of pitch adhesive tape, and also extends to whole bag.
During use, the cable seal bag is shaped with a side surface of gas-filled tube as outer surface, first around the outer surface that wraps cable, sealing bag is bonded as one under the viscous force effect of pitch adhesive tape with cable; Then inflate the cable pressurization sealing bag is expanded, the pitch adhesive tape on bag surface will tightly touch inner-walls of duct, isolates the space of cable and pipeline enclosure fully, reaches Water-proof mouse, guarantees the purpose of the normal operation of cable.
The equal buyable of the above all material obtains.
