Technical field
The utility model relates to a kind of automatic control of liquid level equipment, particularly one oil refining tower bottom liquid level control device.
Background technique
During oil refining tower goes into operation and produces, pump running at full capacity is with governor valve control flow thus control the height of liquid level, and the control operation of adjustment in use valve is frequently unfavorable for that the stability of equipment increases again the use amount of electricity.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and provide a kind of oil refining tower bottom liquid level control device, structure is simple, easy to use, effectively improves pressure release treatment effeciency.
Its technological scheme is: comprise oil refining tower, control valve, oil outlet tube, support, frequency variator, overflow storehouse, oil refining tower is fixed on support, the bottom of described oil refining tower is connected by oil outlet tube overflows storehouse, described oil outlet tube is provided with control valve, described control valve passes through Frequency Converter Control, described control valve comprises feed line, flow line, valve body, spool, valve rod, valve port, diaphragm seal, superpressure definite value sheet, control switch, valve inner is provided with valve pocket, the valve port being communicated with flow line and feed line is provided with in valve pocket, valve body is connected spool with the top of valve pocket, valve rod is provided with in the middle of described spool, valve rod connects diaphragm seal through bottom valve port, described valve rod is provided with superpressure definite value sheet, superpressure definite value sheet connection control switch, control switch is by the action of Frequency Converter Control valve rod.
Be provided with seal ring between above-mentioned valve rod top and valve pocket, improve sealing effect.
The beneficial effects of the utility model are: structure is simple, easy to use, effectively improves pressure release treatment effeciency, improves the pressure release processing time, by Frequency Converter Control control valve switch, improve working efficiency, realize automatically switching, improve the stability of work.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is structural representations of control valve;
In upper figure: oil refining tower 1, control valve 2, oil outlet tube 3, support 4, frequency variator 5, spilling storehouse 6, feed line a, flow line b, valve body 2.1, spool 2.2, valve rod 2.3, valve port 2.4, diaphragm seal 2.5, superpressure definite value sheet 2.7, control switch 2.8.
Embodiment
1-2 by reference to the accompanying drawings, the utility model will be further described:
The utility model comprises oil refining tower 1, control valve 2, oil outlet tube 3, support 4, frequency variator 5, overflow storehouse 6, oil refining tower 1 is fixed on support 4, the bottom of described oil refining tower 1 is connected by oil outlet tube 3 overflows storehouse 6, described oil outlet tube 3 is provided with control valve 2, described control valve 2 is controlled by frequency variator 5, described control valve 2 comprises feed line a, flow line b, valve body 2.1, spool 2.2, valve rod 2.3, valve port 2.4, diaphragm seal 2.5, superpressure definite value sheet 2.7, control switch 2.8, valve body 2.1 inside is provided with valve pocket, the valve port 2.4 being communicated with flow line b and feed line a is provided with in valve pocket, valve body 2.1 is connected spool 2.2 with the top of valve pocket, valve rod 2.3 is provided with in the middle of described spool 2.2, valve rod 2.3 connects diaphragm seal 2.5 through bottom valve port 2.4, described valve rod 2.3 is provided with superpressure definite value sheet 2.7, superpressure definite value sheet 2.7 connection control switch 2.8, control switch 2.8 controls valve rod 2.3 action by frequency variator 5.
Wherein, between valve rod 2.3 top and valve pocket, be provided with seal ring 2.6, improve sealing effect.
Working principle:
In oil refining tower refinery operations process, control valve rod 2.3 action by control switch 2.8 to realize diaphragm seal 2.5 and be elevated, when the inner fluid of oil refining tower is too high, the pressure of control valve 2 inside exceedes the setting value of superpressure definite value sheet 2.7, control switch 2.8 controls valve rod 2.3 and moves downward, valve port 2.4 opened by diaphragm seal 2.5, flow line b is communicated with feed line a, realize the pressure release of oil refining tower, when the inner fluid of oil refining tower is too low, the pressure of control valve 2 inside is lower than the setting value of superpressure definite value sheet 2.7, control switch 2.8 controls valve rod 2.3 and moves upward, diaphragm seal 2.5 shutoff valve port 2.4, valve port 2.4 is closed.
The above is only preferred embodiment of the present utility model, and any those of ordinary skill in the art all may utilize the technological scheme of above-mentioned elaboration to the utility model correct or are revised as equivalent technological scheme.Therefore, any simple modification of carrying out according to the technical solution of the utility model or substitute equivalents, belong to the greatest extent the scope that the utility model is claimed.
