Practical novel content
The utility model provides a kind of cable duct seal bag and valve thereof, by gas nozzle structure is improved, it is achieved repeated inflation and venting, and utilization ratio height, and it is not easy to be subject to the destruction of muroid, sealing property is reliable and stable.
For a valve for cable duct seal bag, comprising:
The outer parts being fixed on sealing bag outer wall, these outer parts have the inlet pipe stretching into sealing bag inside;
The tapered plug being positioned at described inlet pipe, the big head end of tapered plug is inner towards sealing bag;
The inner part being fixed on sealing bag inwall, this inner part has the block piece stoping tapered plug to depart from described inlet pipe.
In the utility model, described inner part and outer parts adopt plastic material, and described tapered plug adopts elastic material.
During inflation, by inlet pipe to sealing bag inner inflatable, tapered plug to offseting with block piece, is formed gas circulation gap by air propels between tapered plug and inlet pipe, and air-flow enters sealing bag inside by gas circulation gap; After inflation, under the air pressure effect of sealing bag inside, tapered plug is pushed into big head end and inlet pipe inwall is fitted completely, it is achieved sealing.
When needing venting, promoting tapered plug and block piece to offset via inlet pipe, sealing bag internal gas is gone out by the gas circulation interstitial row between tapered plug and inlet pipe. The valve that the utility model provides can realize the function inflated and be vented simultaneously, and sealing bag is reused.
As preferably, described outer parts comprise the first chassis being fixed on sealing bag outer wall, and the described inlet pipe being fixed on the first chassis, the first chassis is provided with the inlet mouth being connected with inlet pipe.
Described inner part comprises the 2nd chassis being fixed on sealing bag inwall, and the sleeve pipe being fixed on the 2nd chassis and arranging around described inlet pipe, sleeve pipe is provided with the seal closure of band air inlet port away from the one end on the 2nd chassis, and described block piece is arranged on this seal closure.
When being arranged on sealing bag by valve, the first chassis and the 2nd chassis being placed on the inside and outside both sides of sealing bag respectively, heating and melting realizes the fixing of the first chassis and the 2nd chassis and sealing bag.
In order to proof strength, and make the course of processing simple, it may be preferred that described first chassis and inlet pipe are structure as a whole. Described 2nd chassis, sleeve pipe, seal closure and block piece are structure as a whole. Namely inner part or outer parts are processed by an injection moulding or extruded mode.
As preferably, described block piece is be fixed on seal closure and towards the lug boss of tapered plug. Block piece for preventing tapered plug the air inlet port on sleeve pipe is closed. Described lug boss is multiple, and the gap between each lug boss is induction trunk.
As preferably, described lug boss is 3��6, is evenly arranged around the periphery of air inlet port. Further preferably, described lug boss is 4, is evenly arranged around the periphery of air inlet port.
As preferably, the inner chamber of described inlet pipe is the conical passage matched with tapered plug.
The utility model additionally provides a kind of cable duct seal bag, comprises described valve.
The cable duct seal bag that the utility model provides and valve thereof, by gas nozzle structure is improved, it is achieved repeated inflation and venting, utilization ratio height, and the overall inside being positioned at sealing bag of valve, it is not easy to being subject to the destruction of muroid, sealing property is reliable and stable.
