Nuclear steam self-pressurized water filling rod

Abstract

The invention discloses a nuclear energy steam self-compression water adding rod, wherein the top part of a water adding tank is connected with a steam inlet pipe; a first steam inlet elbow is arranged in a steam inlet pipe orifice; first pressurization space is arranged at the top of the water adding tank; the bottom surface of the first pressurization space is a first water level line; one route of the steam inlet pipe is connected with a nuclear energy steam generator through a pressurization valve, and the other route of the steam inlet pipe is connected with a water delivery tank through an upper-and-lower communicated valve; the bottom part of the water adding tank is connected with the part, below the water level line, of the nuclear energy steam generator through a check valve and a water outlet pipe; an inlet pipeline is arranged at the top of the water delivery tank; one route of the inlet pipeline is connected with the nuclear energy steam generator through a pressurization water delivery valve, and the other route of the inlet pipeline is connected with a steam-water switch tank through a steam-water switch valve; a second steam inlet elbow allowing the incoming steam to rotate on a plane surface is arranged in the inlet of the inlet pipeline; second pressurization space is arranged at the top of the water delivery tank; a second water level line is arranged at the bottom of the second pressurization space; the other route of the bottom of the water delivery tank is connected with the steam-water switch tank through a water delivery check valve; and the water adding tank, the steam-water switch tank and the water delivery tank are mounted in an outer shell entirety from top to bottom.

Description

technical field [0001] The invention relates to a water dispenser, more precisely a nuclear energy steam self-pressurized water filling rod which utilizes the nuclear energy steam's own pressure to add water to a steam generator without additional power. Background technique [0002] Today's world energy crisis is imminent, and the safety of nuclear power has become the focus of controversy. Therefore, the application of this technology can not only reduce the large cost of "adding water" in nuclear power plants, but also reduce the number of large-scale generator sets prepared for emergency by nuclear power plants; it also adds a reliable guarantee to the safety of nuclear power plants . [0003] Since steam was applied to the industry for more than 200 years, the water supply method of the steam generator is still used up to now by using a high-pressure water pump higher than the internal pressure of the container to add water under pressure, especially for large boilers....
