In head chamfering, so phase gas can be vented outward by gap before foaming, when the drained foamed material of air touches institute
After stating foam rods annulus, foam rods by foamed material crimp, so as to block gap so that foamed material will not overflow,
So both accomplish exhaust, in turn ensure that foamed material does not outflow, change the unnecessary waste for needing superfilled material feeding over, section
Raw material has been saved, has improved product quality, economic benefit is very notable.
In order to further improve it is a kind of be incubated channel closure material leak-proof exhaust apparatus use function, the foam rods annulus by
Diameter phi 15mm polyurethane foam pole is through docking and being bonded circlewise.
In order to further improve a kind of use function of being incubated channel closure material leak-proof exhaust apparatus, the working steel tube is
DN200, the working steel tube are spiral weld steel pipe.
In order to further improve a kind of use function of being incubated channel closure material leak-proof exhaust apparatus, the end socket chamfering is in institute
State the inner side at the position that integrated end socket is combined with the working steel tube, the size of the end socket chamfering and the foam rods annulus
Size match.
In order to further improve a kind of use function of being incubated channel closure material leak-proof exhaust apparatus, on the integrated end socket
Provided with the end socket through hole, the size and the external diameter of the working steel tube of the end socket through hole match.
In order to further improve a kind of use function of being incubated channel closure material leak-proof exhaust apparatus, the hard polyaminoester hair
The support is provided with bubble heat-insulation layer, the alarming line is worn in through hole on the bracket.
Beneficial effect is：It machined on the inside of the position that the device combines end socket with steel pipe according to the size of foam rods
Chamfering, exhaust is so both accomplished, in turn ensure that foamed material does not outflow, changed the unnecessary wave for needing superfilled material feeding over
Take, save raw material, improve product quality, economic benefit is very notable.
