THERMAL BATTERY WITH SHUT-OFF VALVE

摘要

The present invention relates to a thermal battery (1) including a storage vessel (3) as well as an inlet pipe (7a) and an outlet pipe (7b) for a fluid, connected to a circulation circuit, said thermal battery (1) also including at least two shut-off valves (9) placed on the fluid inlet pipe (7a) and the fluid outlet pipe (7b), respectively, in order to isolate the fluid contained in the storage vessel (3) when the circulation circuit of said fluid is shut off, said shut-off valves (9) being automatic and including: an enclosure (91) containing fluid and including an inlet (93a) and an outlet (93b) for said fluid; and a float (11) movable between an upper position in which the float floats and obstructs at least the outlet (93b) when the circulation circuit is shut off, and a lower position in which the float is submerged and allows the fluid to circulate between the inlet (93a) and the outlet (93b) when the circulation circuit is operational.
