Abstract
PURPOSE: To have an accurate control of liquid level by providing a pressure sensing valve, which opens and shuts the pressure control conduit in accordance with pressure change in the lower liquid chamber, and thereby eliminating variation of the quantity of liquid in the buoyancy control chamber.
CONSTITUTION: When the level of liquid in a tank T sinks ΔL from the valve closing level L1 to form a level L3, the upper part of the liquid in a pressure control cylinder 2 is blocked by a float valve 13 at the auxiliary line 11 while a pressure control conduit 21 is blocked by a pressure sensing valve 17 and isolated from the atmosphere, so that sink of the liquid level in the tank T down to L3 does not require sink of liquid level in the pressure control cylinder 2 and the liquid level continues to be at the valve closing level L1. Accordingly, the float 3 does not move at all to provide an accurate level control.
