Abstract
The utility model relates to a thermal shrinkage sleeve pipe for a communication cable joint, particularly a connection structure between the thermal shrinkage sleeve pipe and a charge valve. The thermal shrinkage sleeve pipe 1 comprising an inner lining sleeve 2 and a valve hole 3 is provided with a valve seat 9 assembled with the valve hole and the charge valve 8 of a seal and firm piece. The connection structure is arranged between the valve seat and the inner lining sleeve of the thermal shrinkage sleeve pipe. The valve hole is provided with a hole protection structure composed of washers 5, 6 and a hole sleeve 7 which are riveted. In the installation engineering of the cable joint, the charge valve can not fall into the thermal shrinkage sleeve pipe. When heated and packaged, the valve hole can not deform and can not be enlarged. The utility model has the advantages of firmness, reliability, convenient installation, and guarantee of cable communication quality.
Description
The utility model relates to the draw bail of communication cable joint heat-shrinkable T bush, particularly heat-shrinkable T bush and charge valve.
The draw bail of existing heat-shrinkable T bush and charge valve, by the valve opening on the heat-shrinkable T bush tube wall, the valve seat of charge valve and clamp nut constitute.The valve seat pipe portion of charge valve is passed valve opening from the heat-shrinkable T bush inner chamber,, charge valve is packed on the heat-shrinkable T bush with the gas thread of clamp nut and the valve seat pipe portion connection that matches.Valve seat pipe portion is being passed in the installation process of valve opening from the heat-shrinkable T bush inner chamber, and charge valve is easy to fall into the heat-shrinkable T bush inner chamber, and this moment is partition cable joint and heat-shrinkable T bush all, re-assemblies, and has both expended built-up time, causes waste of material again.In addition, during the heat hot Heat-Shrinkable Tubings, under the effect of convergent force, valve opening can be out of shape and even tear in cable installation work, makes heat-shrinkable T bush forfeiture air-tightness, influences communication quality.
Given this, the purpose of this utility model is to provide the draw bail of a kind of solid and reliable, easy for installation heat-shrinkable T bush and charge valve.
The heat-shrinkable T bush of band charge valve of the present utility model (referring to accompanying drawing), the heat-shrinkable T bush (1) that includes neck bush (2) and valve opening (3), have and the equipped mutually valve seat (9) of valve opening and the charge valve (8) of close firmware thereof, between the neck bush of above-mentioned valve seat and heat-shrinkable T bush draw bail is arranged.
Above-mentioned draw bail can have riveting button (12), and this riveting button can be into a single integrated structure and become the flange riveting with valve seat; Also can have and neck bush welded structure mutually.
Above-mentioned valve opening (3) can have the ring washer (5,6) and the annular borehole jack (7) that match.Above-mentioned packing ring can have the jog (4) of annular.
The utility model when assembling, earlier with its draw bail with after the neck bush of heat-shrinkable T bush connects, again charge valve and close the connecting firmly of heat-shrinkable T bush are connect.
The utility model is compared with original structure, has following advantage and effect.
One, draw bail at first is contained in charge valve on the neck bush in advance, passes valve opening and connects firmly when connecing with heat-shrinkable T bush is mutually close at charge valve, and charge valve can not fallen into the heat-shrinkable T bush inner chamber, has eradicated the hidden danger of doing over again and installing, and can not cause expending and waste of material of time.
Two, the packing ring of heat-shrinkable T bush valve opening portion and borehole jack constitute the protection structure of valve opening; in the cable joint engineering; when contracting heat-shrinkable T bush with flame is roasting; the valve opening of heat-shrinkable T bush can not be out of shape expansion; more can not be torn and lose air-tightness; particularly when employing had the packing ring of annular concave-convex portion, the valve opening peritreme forms concavo-convex ring-type thereupon, and was more excellent to the valve opening protection.
Below, use embodiment and accompanying drawing thereof again, the utility model is described in further detail.
Brief description of drawings.
Fig. 1 is the structural representation of a kind of heat-shrinkable T bush with charge valve of the present utility model.Show the state after the cable joint assembling is finished, omit cable joint portion among the figure.
Fig. 2 is the heat-shrinkable T bush of Fig. 1 and the local structure for amplifying schematic diagram of charge valve connection part.
A kind of heat-shrinkable T bush of the present utility model with charge valve, as shown in drawings.By heat-shrinkable T bush, charge valve and close firmware constitute.
Above-mentioned heat-shrinkable T bush 1 is made tubular with common material contracting with heat.The metal neck bush 2 that matches is arranged in the heat-shrinkable T bush.Open at the suitable position of the two tube wall and to be shaped on the valve opening 3 that matches.A metallic packing ring 5 and a packing ring 6 that concentric annular concave-convex portion 4 is arranged is respectively arranged inside and outside the valve opening of heat-shrinkable T bush 1, borehole jack 7 with the metallic annular runs through valve opening, packing ring 5 and packing ring 6 and this valve opening portion rivet clasp of heat-shrinkable T bush are in the same place, constitute the valve opening structure of composite material.The valve opening portion of neck bush 2 is recessed to the tube cavity direction.
Above-mentioned charge valve 8, main body adopts common structure, and the valve seat 9 of pipe portion is arranged, spool 10 is arranged in the valve seat 9, and the pipe portion of valve seat is shaped on external screw thread, and there is the chassis 11 with valve seat all-in-one-piece toroidal ring piece shape the valve seat lower end, the below, chassis has and chassis all-in-one-piece riveting button 12, and before unassembled, riveting is fastened as cylindrical shape.
The common seal washer 13 of the useful flexibility heat-resisting material system of above-mentioned close firmware and with the clamp nut 14 of the pipe portion threads engaged of valve seat.
During assembling, earlier the cylindrical shape riveting button 12 of valve seat is inserted the valve opening of neck bush 2, turn over button cylinder limit and become the riveting button, charge valve is contained on the neck bush in advance.Again with valve seat 9 pipe portions covers sealing filler ring 13, then with neck bush, the heat-shrinkable T bush 1 of packing into, and the pipe portion of valve seat 9 passed the valve opening of heat-shrinkable T bush from inner chamber, at last with the clamp nut rotation set in valve seat pipe portion and tighten up.
Above-mentioned charge valve connects with neck bush, also can adopt welding to connect.
Use the utility model, cable joint 15 is placed the neck bush of heat-shrinkable T bush,, make heat-shrinkable T bush shrink and be airtight shape, after the charge valve inflation, can put into operation with heating tool heat hot Heat-Shrinkable Tubings such as blowtorch.
