hydraulic device float type level gauge and this liquid level gauge is attached

摘要

To provide a visual form liquid level gauge which is attached to the liquid tank side wall, with a simple structure and small number of parts, it is possible to check the liquid level is not limited to the direction and further to combine the air breather and injected opening feature It provides a liquid level gauge. A flange 6 of the upper end portion in the opening 4 of the ceiling of the liquid tank 2 has been suspended from the hanging sealed with the liquid tank 2, free access possible annular body is vertically divided liquid by a partition 5 7, a first piston 11 having a small diameter cylindrical body 10 which Expressway bottom together are vertically movably provided inside of the partition 5 at the top of the partition 5, and a vertically movable upper portion of the partition 5 together are internally provided to become the second piston 12. which is inserted in the cylindrical body 10 of the small diameter, the first piston 11 is floated until it abuts against the partition 5 by the buoyant force, then the second piston 12 is floated We want to display the liquid surface Te. .BACKGROUND
