Rapid water draining inflating device and method of nuclear island water system container

Abstract

The invention discloses a rapid water draining inflating device and method of a nuclear island water system container, and solves the technical problems that an existing nuclear island water system container drains water slowly, and the water cannot be evacuated completely. The inflating device comprises a safety water draining pressure intensity calculating module 100 and an inflating assembly (200), wherein the safety water draining pressure intensity calculating module 100 is used for determining safety water draining pressure intensity of the container (1); the inflating assembly (200) is used for inflating the container (1) so that water is drained when the container (1) is pressurized to the safety water draining pressure intensity; the inflating assembly (200) comprises an air inlet pipeline (2) which communicates with the container (1) and a nuclear island public compressed air distributing system (SAT); and the air inlet pipeline (2) comprises first and second air inlet pipe sections (21 and 22), a first isolating valve (3) and a pressure measuring device (4). High-efficiency and high-quality water draining of the nuclear island water system container is realized; meanwhile, labor can be simplified greatly during water draining adjustment of the container, safety factors of water draining are increased, investment is low, and practicality is good; and the inflating assembly is simple in structure, simple to mount and convenient to carry.

Description

technical field [0001] The invention relates to the technical field of commissioning and operation of a nuclear power plant water system, in particular to a device and method for rapidly draining and inflating containers of a nuclear island water system. Background technique [0002] During the commissioning process of the water system of a nuclear power plant, it is inevitable to encounter the problem of "container drainage". At the end of a large-scale joint commissioning of a nuclear power plant, a single system test, or a flushing, etc., it is inevitable to drain and eliminate deficiencies. "Drainage" has always been a common problem in various nuclear power plant systems. Usually drainage is done according to the water level and gravity of the water in the container, but for some containers (especially large and medium-sized containers), from a design point of view, they cannot be installed at a higher position due to their own volume and weight. This factor seriously...
