Abstract
The utility model discloses an air bag for sealing the main pipe of a steam generator of nuclear power station, which comprises a chamber, a cover plate adhered with the chamber to form a sealed chamber, a handle fixed at the outer side of the cover plate, an aeration rubber tube for aerating the sealed chamber and an air nozzle for plugging the rubber tube, wherein a balance tube is provided at the middle of the chamber, the outer end of the chamber is provided with a reinforce pad, the cover plate is a nitrile rubber plate, and the handle is a nylon embedded type handle. The air bag can quickly and simply discharge foreign materials with confirmed foreign material discharge of the main pipe of steam generator and the liquid level fluctuation of the main system, to shorten working time and reduce the labor strength and radiation dosage on repair personnel.
Description
Technical field
The utility model belongs to a kind of air bag, is specifically related to a kind of air bag that is used for blocking pipe.
Background technique
Steam generator is the key equipment in the nuclear power station owner heat-transfer system, the service work relevant with steam generator, need take effectively anti-foreign matter measure, the main pipe of steam generator is carried out shutoff in order to avoid cause foreign matter to enter in the main system other key equipment in the system (as main heat transport pump, reactor etc.) is damaged.The traditional foreign matter eliminating measure of nuclear power station is to adopt metal cover board, and the installation steps of the anti-foreign matter metal cover board of steam generator main pipe are: open the primary side of steam generator manhole; Primary side of steam generator silt water white-out; Tapped hole on the cleaning primary side of steam generator inwall; Personnel enter primary side of steam generator; At the main pipe opening metal cover board is installed; Fastening cover plate attachment bolt; Personnel withdraw from primary side of steam generator.
In order to prevent intrasystem level fluctuation, metal cover board adopts engage thread to connect with the inwall of steam generator; Install time-consuming, consumption power and personnel and will enter the internal work of steam generator, the radiation dose of reception is very big.
Summary of the invention
The purpose of this utility model be to provide a kind of can guarantee steam generator main pipe foreign matter got rid of and the prerequisite of main system level fluctuation under, can conveniently carry out the foreign matter eliminating measure, shorten working hours, reduce maintainer's the labor intensity and the air bag that is used for shutoff nuclear power station steam generator main pipe of radiation dose.
Realize the technical solution of the utility model: a kind of air bag that is used for shutoff nuclear power station steam generator main pipe, it comprises the air bag cavity, is bonded to the valve that the cover plate of sealed cavity, the handle that is fixed in the cover plate outside, the inflation sebific duct that can inflate and energy jam-pack are inflated sebific duct with the air bag cavity in sealed cavity, wherein, in the middle of the air bag cavity, be provided with a balance tube, the external end of airbag chamber is provided with strengthens pad, cover plate is the nitrile butadiene rubber plate, and handle is the nylon material flush type handle.
The beneficial effects of the utility model are: change traditional metal cover board into air bag that main material is nitrile butadiene rubber and folder cloth nitrile butadiene rubber, tightly fit to play fixing effect with steam generator main pipe inwall behind the airbag aeration, can cross the shutoff that realizes effectively the steam generator main pipe, and the installation of air bag and the dismounting all very time saving and energy saving.Balance tube on the air bag cavity can be monitored the variation in pressure of balance main pipe level fluctuation, prevents that air bag is ejected or the inspiration main pipe; The handle of air bag adopts embedded with convenient installation in narrow space, dismounting air bag; Can play leading role behind the reinforcement pad gas of air bag inside; Enough conveniently carry out the foreign matter eliminating measure, shorten working hours, reduce maintainer's labor intensity and radiation dose.
