PURPOSE:To always stabilize operation of a float by providing a ball valve for fluid supply under a flat opening. CONSTITUTION:A ball valve 4 is provided on the tip of a fluid supply pipe 3 so as to be located under the opening of a float 1. Hereby, liquefied gas supplied from the fluid supply pipe 3 evaporates in response to the internal pressure of the float 1 when it flows into the float 1, allowing evaporated gas to be filled up in the float 1, so that a gas volume within the float 1 is not reduced even if the pressure within a tank is changed, enabling the float 1 to always make steady operation. |
