STATION FOR STORING, COLLECTING AND RECIRCULATING A FLUID SUBSTANCE

摘要

Station (10) for internally and externally storing, collecting and recirculating a fluid substance, said station (10) comprising a tank (11) and a recirculation circuit (14) of the fluid substance contained in said tank (10). The circuit (14) is provided with a first end associated with a lower supply opening (12) and a second end associated with an upper loading opening (13); the circuit (14) being provided with a pump (15) and a first valve (16) associable with an external tank (17) through a loading conduit (18), the valve (16) being configurable for selectively defining the conditions of recirculation of the fluid substance contained in said tank (11) from the lower opening (12) to the upper opening (13) isolating said external tank (17), and loading the fluid substance from said external tank (17) to said tank (11) isolating the lower supply opening (12) of said tank (11). The recirculation circuit (14) comprises a second valve (19) being configurable for selectively defining the conditions of advancement of the fluid substance coming from the first valve (16) along the recirculation circuit (14) towards the upper opening (13) and diverting the fluid substance coming from the first valve (16) of the recirculation circuit (14) towards the external tank (17) through a return duct (20).

主权项

1. A storage, collection and internal and external recirculation station of a fluid substance, said station comprising a tank equipped with a lower supply opening and an upper loading opening and a recirculation circuit of the fluid substance contained in said tank; said recirculation circuit being equipped with a first end associated with said lower supply opening and a second end associated with said upper loading opening; between said first and second end of said recirculation circuit, there being provided a pump and a first valve, said valve being associable with an external tank through a loading duct and being configurable to selectively define the conditions of:
recirculation of the fluid substance contained in said tank through said recirculation circuit from said lower supply opening to said upper loading opening, isolating said external tank; and charging the fluid substance from said external tank to said tank, isolating the lower supply opening of said tank; wherein said recirculation circuit comprises a second valve downstream of said first valve following the flow of the fluid substance; said second valve being associable with said external tank through a return duct and being configurable to selectively define the conditions of: advancement of the fluid substance coming from said first valve along said recirculation circuit towards said upper loading opening; and deviation of the fluid substance coming from said first valve in said recirculation circuit towards said external tank through said return duct.
