Abstract

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.

When unloading gasoline or diesel oil from a tanker truck to an oil storage tank, a single oil supply pipe is shared, so it is possible to mistake the type of oil (gasoline, diesel oil, etc.) and unload oil of a different type. . When such a situation occurs, the mixed oil becomes a mixture of gasoline and diesel oil, or gasoline and kerosene, which cannot be used. Therefore, if an oil type discrimination device is provided in the oil supply pipe when unloading, there is no possibility that such an inconvenient situation will occur.

When W< turns on, the current flows through the normally closed contacts T Ra and R
3d, the relay R1 works, and the relay R1
The normally open contact R1a is closed, and the three-way switching valve 18 is switched from the closed state to allow oil to flow into the bypass pipe 22. Therefore, the oil in the tank chamber 2 is supplied to the housing 23 little by little through the bypass pipe 22. Then, after a certain number of seconds, for example 5~
After 6 seconds have elapsed, the inside of the 70-]-chamber 23a is filled with oil, and the oil begins to flow down from the hole 26 of the A-bar 70.

The timer relay TR, which is set to longer than the time required for the float chamber 23a to be filled with oil to determine the oil type, for example 10 seconds, operates after the set time of 10 seconds, and the relay contact TR
Open al and close relay contact T Rb. As a result, the relay R2 is activated, closing the contact R2a, and the three-way switching valve 18 is switched to close the bypass pipe 22 side and open the lubrication @14 side, and the oil storage tank 7 is refilled. The regular gasoline in the float chamber 23a flows out from the small hole 27 into the oil supply pipe 14 and is prepared for the next oil type determination.

Also, the relay contact R3c is closed and the alarm 12 is activated. Further, the relay contact R3d is heard, and as a result, the relay R1 is deenergized, the relay contact R1a is opened, and the three-way switching valve 18 is closed to stop the inflow of light oil. If it is determined that erroneous refueling has occurred in this manner, the starting switch S W t is turned off, the tank chamber is selected again, and correct refueling is performed.

J5 The above embodiment prevents the malfunction of pouring light oil into the gasoline filler pipe, but in order to prevent the malfunction of pouring gasoline into the light oil filler pipe, the specific gravity n1 is set to the specific gravity H1 for light oil. If the correct light oil is in the float chamber 23a
The flow 1 switch turns on in 5 to 6 seconds when gasoline flows into the tank, and the float switch remains off even after 5 to 6 seconds when gasoline accidentally flows in, so the float switch is turned on and off. All you have to do is to use the signal to control the alarm and three-way switching valve.
