Description
Technical field
The utility model belongs to nuclear fuel reprocessing technology field, and in particular to a kind of to be torn open for the remote of channel seal
The flange apparatus of dress.
Background technology
Element shearing hot cell walkthrough wind filtration system original design is using the pre- air draft of push-in type being arranged on the wall of hot cell
Filter system, because the design can not set filter positioner, and former design duct push-in, apart from long, operating personnel can not
Accurate observation is installed in place, and it is inaccurate to be easily caused positioning, so that air draft duct and hot cell are led directly to, does not have cartridge sealing
Effect, cause in follow-up exhaust Air Cleaning case just, high efficiency particulate air filter core dosage it is exceeded, need to frequently change.Therefore it is to original filtering
System is rectified and improved, and pre- exhaust-air filter is arranged on inside hot cell, and exhaust duct is connected by the air draft duct on former hot cell wall,
The connected mode is connected using flange.To solve the sealing problem in hot cell and former air draft duct, while being easy to exhaust duct
Demolition, installation, flange apparatus need to possess simple in construction, firm, while the features such as being easy to the remote demolition, installation of power hand.Therefore need to set
Meter is a kind of to be applied to hot working environment, strong dust, and favorable sealing property, is easy to the flange apparatus far torn open.
The content of the invention
The purpose of this utility model be to provide it is a kind of with stabilized structure, simple and favorable sealing property be used for hole
The flange apparatus of the sealed remote disassembling in road.
To reach above-mentioned purpose, technical solution adopted in the utility model is：
In a kind of flange apparatus of remote disassembling for channel seal, including flange plate A and flange plate B, flange plate A
Surface is provided with annular groove, and flange plate B inner surface settings have annular boss, flange plate A annular groove and flange plate B annular
Boss is docked；Averagely it is disposed with flange plate A on aperture identical bolt hole, flange plate B and is averagely disposed with aperture identical spiral shell
Keyhole, flange plate A is bolted with flange plate B.
Described annular groove 1 is a diameter ofPolytetrafluoroethylene gasket is installed in annular groove 1.
Described annular boss 5 is a diameter of
Described flange plate A is welded with former air draft duct.
Described flange plate B is welded with filter housings airduct.
Described annular groove 1 and the rounded at the edge of annular boss 5 are sharp.
The measurement pipe that two a diameter of 17 × 3mm of Φ are provided with described flange plate B stretches out duct 6.
Having the beneficial effect that acquired by the utility model：
The utility model meets the sealing index request of radioactive dust place air draft, and filter pressure difference change is little,
In process operation requirement, favorable sealing property, and it is easy to remote disassembling to operate, step is simple, and usage cycles are long.
