Without intuitively alarm and safety guarantee when too low, so as to cause oil pump idle running damage and other dangerous situations to occur.
Utility model content
For the problems referred to above that prior art is present, the purpose of this utility model be to provide one kind can realize it is remaining in oil tank
The device of oil quantity alarming.
For achieving the above object, the technical solution adopted in the utility model is as follows：
A kind of device for realizing remaining oil quantity alarming in oil tank, including source of the gas, the first liquid level valve, first pressure switch, warning
Device, the second liquid level valve, second pressure switch and bottom valve, first liquid level valve, second liquid level valve and the bottom valve root
It is successively set in oil tank from high to low according to place liquid level, the source of the gas is logical with first liquid level valve and second liquid level valve
Trachea connection is crossed, the first pressure switch is connected with first liquid level valve by trachea, the alarm and described first
Pressure switch is electrically connected, and the second pressure switch is connected with second liquid level valve by trachea with the bottom valve.
Preferably, first liquid level valve is located at 600～800 liters of liquid levels of oil tank, second liquid level valve
At 50～150 liters of liquid levels of oil tank.
Preferably, the alarm is audible-visual annunciator.
Compared to prior art, Advantageous Effects of the present utility model are：
What this utility model was provided realizes that the device of remaining oil quantity alarming in oil tank is capable of achieving in timely automated prompting oil tank
Excess oil amount situation, can effectively prevent oil pump idle running from causing device damage or causing more serious safety problem, with practical value.
Description of the drawings
Fig. 1 is a kind of apparatus structure schematic diagram for realizing remaining oil quantity alarming in oil tank that this utility model is provided.
In figure, label is schematically as follows：1- oil tanks；2- sources of the gas；The first liquid level valves of 3-；4- first pressures are switched；5- alarms；
The second liquid level valves of 6-；7- second pressures are switched；8- bottom valves.
Specific embodiment
The technical solution of the utility model is described in further detail below in conjunction with accompanying drawing.
As shown in figure 1, a kind of device for realizing remaining oil quantity alarming in oil tank that this utility model is provided, including oil tank 1, gas
Source 2, the first liquid level valve 3, first pressure switch 4, alarm 5, the second liquid level valve 6, second pressure switch 7 and bottom valve 8, first
Liquid level valve 3, the second liquid level valve 6 are successively set in oil tank 1, in the present embodiment according to place liquid level from high to low with bottom valve 8,
First liquid level valve 3 is arranged at 750 liters of liquid levels of oil tank 1, and the second liquid level valve 6 is arranged at 100 liters of liquid levels of oil tank 1, but this
Not with this level set as limiting, technical staff can be designed utility model according to practical situation, and bottom valve 8 is arranged at low
To fuel-displaced at the liquid level of the second liquid level valve 6.Source of the gas 2 is connected by trachea with the first liquid level valve 3 and the second liquid level valve 6, is used
To provide compressed air.First pressure switch 4 is connected with the first liquid level valve 3 by trachea, and alarm 5 switchs 4 with first pressure
Electrical connection.Second pressure switch 7 is connected with the second liquid level valve 6 by trachea with bottom valve 8.
Operation principle of the present utility model is as follows：
In the case that the liquid level of oil is higher than the first liquid level valve 3 and the second liquid level valve 6 in the oil tank 1, the first liquid level valve 3 with
And second liquid level valve 6 all in open mode, the compressed gas that now source of the gas 2 is provided are transmitted through pipeline, respectively by first
Liquid level valve 3 and the second liquid level valve 6 are input into first pressure switch 4 and second pressure switch 7, in the effect of compressed gas
Under, first pressure switch 4 and second pressure switch 7 are remained off, therefore, will not report to the police and termination of pumping action.
In the case that in oil tank 1, oily liquid level is less than the first liquid level valve 3 and is higher than the second liquid level valve 6, the first liquid level valve 3
Close, the second liquid level valve 6 is remained on, now the tracheal strips between first pressure switch 4 and the first liquid level valve 3 are died,
Therefore first pressure switch 4 will be closed, and so as to send the signal of telecommunication to alarm 5, triggering alarm 5 works, and second pressure
Switch 7 is still remained off in the presence of compressed gas, will not trigger termination of pumping action.
In the case that the liquid level of oil is less than the first liquid level valve 3 and the second liquid level valve 6 in the oil tank 1, the first liquid level valve 3 with
And second liquid level valve 6 all in closed mode, the compressed gas that now source of the gas 2 is provided cannot pass through the first liquid level valve 3 and the
Two liquid level valves 6 for into first pressure switch 4 and second pressure switch 7, therefore, first pressure switch 4 and second pressure
All in closure state, now, the closure of first pressure switch 4 can send the signal of telecommunication to alarm 5 to power switch 7, and triggering is reported to the police
Device 5 works, and the closure of second pressure switch 7 causes bottom valve 8 to lose compressed gas and closes and second pressure switch is 7 to outside
Oil pump sends the signal of telecommunication, so that oil pump quits work.
Visible in sum, it is timely automated that what this utility model was provided realizes that the device of remaining oil quantity alarming in oil tank is capable of achieving
Excess oil amount situation in prompting oil tank, can effectively prevent oil pump idle running from causing device damage or causing more serious safety problem,
With practical value.
Finally be necessary it is pointed out here that be：The foregoing is only this utility model preferably specific embodiment, but this
The protection domain of utility model is not limited thereto, and any those familiar with the art is disclosed in this utility model
In technical scope, the change or replacement that can be readily occurred in should all be covered within protection domain of the present utility model.
