Abstract

The invention provides a ball falling valve dust filtering device for an absorption ball shutdown system of a high temperature gascooled reactor. The ball falling valve dust filtering device is characterized by comprising a ball falling valve dust filtering stainless steel sheet (1), a ball falling valve head tray (3), a dust discharge screw (4), a ball falling valve head (5), a dust discharge hole plate (8) on the stainless steel plate (1) and an elastic movable plate (9) on the stainless steel sheet (1), wherein the dust discharge screw (4) is connected to the lower surface of the ball falling valve head (5), and the stainless steel sheet (1) is fixed at the bottom part of the valve head tray (3). The dust filtering device is designed for dust accumulated in the ball falling valve head, and can be used for reasonably discharging fine dust collected, and guaranteeing the normal operation of the ball falling valve of the absorption shutdown system driving mechanism.

Description

technical field [0001] The invention relates to the technical field of nuclear reactor engineering and safety, in particular to a ball valve dust filtering device used for a high-temperature gas-cooled reactor absorption ball shutdown system. Background technique [0002] In nuclear reactor safety technology, the high temperature gas-cooled reactor absorber ball shutdown system sends the absorber ball out of the core through the gravity drop of the graphite absorber ball containing boron carbide and helium gas transportation, and cooperates with the use of control rod components to change the neutron absorption of the core rate, thereby changing the reactivity and realizing the control of the fission reaction, that is, realizing the power control. In addition, when the absorbing ball shutdown system is put into use alone, it can also fully realize the cold shutdown function. And considering the principle of fail-safe design and implementing it into the design of important s...
