发明名称 DEVICE FOR PREVENTING SUPPLY OF IMPROPER OIL TO STORAGE TANK
摘要 PURPOSE:To prevent improper oil from being supplied to a storage tank by providing a device for distinguishing the kinds of oils to the oil filling pipe for a storage tank and controlling the opening and closing of the valve provided on the oil filling pipe by means of the output of said oil-kind distinguishing device. CONSTITUTION:An oil filling pipe 14 connected to the storage tank of a filling station is coupled to a hose 21 on the tank-lorry side through a coupling 20. A three-way selector valve 18 is provided to the oil filling pipe 14 and a bypass pipe 22 is connected between one outlet of the selector valve 18 and the oil filling pipe 14. In the bypass pipe 22 is formed a housing 23, in which a float 24 is vertically movable housed, while a float switch SW2 actuated by the float 24 is also provided. When the oil being filled is the right one, the float 24 is not floated up to the dotted-line position 24a, thereby without causing the switch SW2 to be turned on. If the oil is a wrong one, the float 24 is floated up causing the switch SW2 to be turned on. This causes the three-way selector valve 18 to close, stopping the filling of this oil.
