Description
Technical field
The present invention relates to oil-gas mining safety control technology fields, and in particular to a kind of petroleum tank for being exclusively used in carried of crude oil
Fluid level control device.
Background technology
Existing crude oil storage tank is in operation, it is necessary to field observation liquid level, control electrical heating and oil-well motor control manually
Device, such as operation not in time, are susceptible to security incident, particularly winter, do not start electric heater unit in time such as, be easy to cause
Crude oil is congealed in tank, and the accidents such as oil are run in pipeline bursting by freezing.When the liquid level in crude oil storage tank reaches the safety levels upper limit, if not and
Shi Faxian be easy to cause crude oil storage tank tank boil-overs accident；When the liquid level in crude oil storage tank reaches safety levels lower limit, if not and
Shi Faxian be easy to cause heating unit dry combustion method and triggers fire incident.
The patent of invention that number of patent application is 201420365658.8 discloses a kind of crude oil storage tank and is filled with security control
It puts, the crude oil storage tank is arranged on safety control between crude oil storage tank, distribution box, electric heater unit and oil-well motor,
Buoy is equipped in the crude oil storage tank, the electric heater unit and the oil-well motor are connected with the distribution box, the safety
Control device includes liquid level gauge and driving member, and the liquid level gauge includes Liquid level scale cylinder and in the Liquid level scale cylinder
The "painted-face" character in opera in portion, upper magnetic sheet, lower magnetic sheet, upper magnetic attraction switch and lower magnetic attraction switch, the "painted-face" character in opera pass through the driving member
It is connected with the buoy, the upper magnetic sheet is mounted on the lower magnetic sheet on the "painted-face" character in opera, the upper magnetic attraction switch and institute
It states electric heater unit to be connected, the lower magnetic attraction switch is connected with the oil-well motor.When liquid level reaches the peace of crude oil storage tank
During full liquid level lower limit, by the movement of "painted-face" character in opera, magnetic sheet is attracted with upper magnetic attraction switch in drive, control electric heater unit circuit
It is automatic to disconnect, stop electrical heating, avoid oil-free electrical heating dry combustion method in crude oil storage tank；When liquid level rises to the safe liquid of crude oil storage tank
It during the upper limit of position, is moved by "painted-face" character in opera, lower magnetic sheet is driven to be attracted with lower magnetic attraction switch, control oil-well motor circuit disconnects automatically
Stop well, stop to crude oil storage tank oil inlet, prevent crude oil storage tank tank boil-overs, therefore the present invention has safety coefficient high, stability is good,
Not only the advantages of security incident can be avoided, but also can guarantee equipment normal operation.In addition, the safety control can be long-range indoors
Control, grasps liquid level convenient for employee, realizes and automatically control operation in time, therefore can also effectively reduce labor intensity, simultaneously also
There is simple operation.
But substantially, above-mentioned petroleum tank heating unit is electrical heating, and safety control is also solenoid valve, with what is used
It carries out, it is understood that there may be problems with：
Short circuit occurs for the 1st, electric heating line aging, generates electric spark, and local environment is the higher environment of gas concentration,
Once electric spark generates, security incident easily occurs；
2nd, the circuit-line of petroleum tank liquid level is controlled once to break down, it is impossible to play the purpose of control petroleum tank liquid level；
3rd, for heating crude oil temperature, it is only necessary to crude oil temperature be controlled to maintain 20-40 DEG C in winter, electrical heating
Temperature-controllable is poor, and heating temperature is excessively high to be easy to cause in petroleum tank that gas evaporation amount is big so that and air pressure is excessively high in petroleum tank,
And then security incident may be caused, while electrically heated mode is used, electric heating wire can generate part with petroleum tank contact position
The situation of temperature excursion, there is also security risks.
The content of the invention
The present invention provides a kind of petroleum tank fluid level control device for being exclusively used in carried of crude oil, to solve existing control petroleum tank
The technical issues of circuit-line of liquid level once breaks down and cannot play the purpose of control petroleum tank liquid level.
In order to solve the above technical problems, the present invention uses following technological means：
A kind of petroleum tank fluid level control device for being exclusively used in carried of crude oil, including floating on the floating of petroleum tank inner fluid surface
Plate and at least three leads being fixed on inside petroleum tank, set in the kickboard with the corresponding pilot hole of lead,
