Desalted water treatment filtering device

The utility model belongs to the technical field of nuclear power plant debugging, and particularly relates to a demineralized water treatment filtering device which comprises a body, a power mechanism, a connecting mechanism, a valve mechanism, a pressurizing mechanism, a filtering barrel and a high-density permeation pipe. The connecting mechanism is fixedly connected to the upper side of the outer side wall of the filter barrel, the valve mechanism is slidably connected to the middle of the left side of the outer side wall of the body in a penetrating mode, the pressurizing mechanism is connected to the middle of the right side of the outer side wall of the body through a bolt, and the filter barrel is clamped to the upper side of an inner cavity of the body through the connecting mechanism. And the high-density permeation tube is positioned on the lower side of the inner cavity of the body. By using the sectional type shielding device, under the condition that maintenance and inspection activities are not
