Coding in attached drawing is respectively as follows: 1 for general piping for liquids, and 2 be fluid reservoir, and 3 be feed flow branch pipe, and 4 be liquidometer, and 5 be confession
Liquid pump, 6 be automatic regulating valve, and 7 be flowmeter.
Specific embodiment
The utility model is not limited by following embodiments, can technical solution according to the present utility model and actual conditions
Determine specific embodiment.
In the present invention, for ease of description, the description of the relative positional relationship of each component is according to specification
The Butut mode of attached drawing 1 is described, such as: the positional relationship of upper and lower, left and right is the Butut according to Figure of description
Direction determines.
The utility model is further described below with reference to examples and drawings:
As shown in Fig. 1, which includes fluid reservoir 2 and the storage of general piping for liquids 1, at least two
The feed flow branch pipe 3 that 2 quantity of flow container matches；The tank bottom of each fluid reservoir 2 is connected with one end of a feed flow branch pipe 3, and every
The other end of feed flow branch pipe 3 is connected with general piping for liquids 1, is equipped with and can monitor in tank in the outside of each fluid reservoir 2
The liquidometer 4 of liquid level is serially connected with solution feed pump 5 on every feed flow branch pipe 3, concatenates on every feed flow branch pipe 3 after solution feed pump 5
There is automatic regulating valve 6, flowmeter 7, each fluid reservoir 2 and the formation of feed flow branch pipe 3 communicated therewith are serially connected in general piping for liquids 1
One feed flow branch, in every road feed flow branch: the signal output end of liquidometer 4 and the signal input part of automatic regulating valve 6 are electrically connected
It is connected together.
Start the solution feed pump 5 in every road feed flow branch, automatic adjustment is manually opened according to the case where each liquidometer 4
Valve 6, adjusts the rate of discharge of each solution feed pump 5 respectively, observes flowmeter 7 in adjustment process, this process be an artificial, middle control by
The process for walking compounding practice, while paying close attention to the measurement result of flowmeter 7, when regulating valve manual adjustment is to certain valve location
It waits, flowmeter 7 stablizes output simultaneously, and without obvious fluctuation, system is manually switched to automatic adjustment, enters multi-level at this time and adjusts automatically
The process of section, automatic regulating valve 6, liquidometer 4 and flowmeter 7 finally realize dynamic auto adjusting in real time.The utility model is realized
The process of multi-level automatic adjustment: firstly, on the control panel, liquid level summation after being added is shown according to each liquidometer 4, and
The liquid level of each fluid reservoir 2 proportion in liquid level summation is calculated, the ratio of the liquid level summation shared by the liquid level of some fluid reservoir 2
Example is big, then the automatic regulating valve 6 in the road feed flow branch is just opened greatly, the liquid level summation shared by the liquid level of some fluid reservoir 2
Ratio is small, then the automatic regulating valve 6 in the road feed flow branch just open it is small, secondly, the total aperture of all automatic regulating valves 6 is to want
With flowmeter 7 set regulated value variation and change, on the control panel when flowmeter 7 show it is bigger than the regulated value of setting,
The total aperture of all automatic regulating valves 6 will turn down at this time, all at this time automatic when the value for the ratio setting that flowmeter 7 is shown is small
The total aperture of regulating valve 6 will be opened greatly, also, when the total aperture of all automatic regulating valves 6 changes with flowmeter 7 and changed,
The scale of each automatic regulating valve 6 liquid level summation according to shared by respective 2 liquid level of fluid reservoir, auto-open-close adjust automatic adjust
Save valve 6；Meanwhile each liquidometer 4 is equipped with low alarm, low alarm, height alarm, the high alarm of height, controls operation in prompt and connects
Lock movement, when the extreme cases such as occur alarming have: 1, when some liquidometer 4 low alarm, alarm message reminding operator's tank
The low alarm of interior liquid level, 2, when the low alarm of some liquidometer 4, the automatic regulating valve 6 in the road feed flow branch is fixed on 10% and opens
The valve position of degree, prevent the automatic regulating valve 6 in the road feed flow branch from closing the feed flow avoided in the road feed flow branch entirely
Pump 5 out of service, valve can be manually operated in operator at this time, when the liquidometer 4 of the fluid reservoir 2 in the road feed flow branch is aobvious
When indicating value is restored to the automatic adjustment value of setting, the automatic regulating valve 6 in the road feed flow branch is automatically added in regulating loop,
According to target value automatic regulating valve 6,3, when some liquidometer 4 reaches high alarming value, alarm message reminding technique liquid level is high
Alarm, 4, when some liquidometer 4 reaches high linkage value, the automatic regulating valve 6 in the road feed flow branch cuts out regulating loop,
Valve can be manually operated in operator at this time, after the liquid level of the fluid reservoir 2 in the road feed flow branch restores normal setting, throw
Enter automatic regulating system.
The utility model provides a kind of multi-level self-checking device, is related to the automatic adjustment of multi-parameter, the device
The problem of multi-level influences each other can be effectively solved, is automatically adjusted by multiple automatic regulating valves 6 so that all fluid reservoirs 2
Liquid level and rate of discharge reach dynamic equilibrium.Operator only needs to put into automatically after steady production, and according to production
Need to be arranged alarming value and control target value, operator need to only do data monitoring appropriate, and this method alleviates behaviour
Make personnel labor intensity, improves labor productivity.
The above technical characteristic constitutes the most preferred embodiment of the utility model, with stronger adaptability and best implementation
Effect can increase and decrease non-essential technical characteristic, according to actual needs to meet the needs of different situations.
