Description
Technical field
the utility model related to boiler water level control field, particularly related to a kind of boiler float-ball type liquid
Level sensor.
Background technology
boiler is generating, oil refining, the important energy source equipment of the industrial sectors such as chemical industry.Boiler is wanted can safety, and reliably, effectively run, operational factor can arrive design load, except boiler in-house facility and various subsidiary engine intact except, also necessarily require that instrument and meter for automation is working properly and design proposal that is automatic control system is correct.
Boiler water level controls to be one of essential condition ensureing boiler safety use, water lev el control can allow people grasp the height of boiler internal water level timely accurately, thus determine that boiler is interior the need of water inlet, prevent boiler internal cause to lack the generation causing security incident.
Controlling middle water level sensor at boiler water level is indispensable Important Components, electrode sensor is used when boiler feed water level sensor level sensor starts most, developed into electromagnetic sensing formula afterwards, the performance of traditional electrode sensor is very big by the impact of incrustation scale, serviceable life is of short duration, within a short period of time will because of incrustation scale problem can not be correct the accurate water level signal of transmission to controller, thus affect the normal use of boiler, there is great potential safety hazard, and electromagnetic sensing formula causes boiler overall price expensive because its production cost is too high, can not get the accreditation of users, be difficult to popularize.
Utility model content
The technical matters that the utility model mainly solves is to provide a kind of New-type boiler floating ball type liquid level sensor, overcome the impact that incrustation scale transmits water level signal, can transmission water level signal promptly and accurately to controller, guarantee boiler use safety, simultaneously easy for installation, price economy material benefit.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of boiler floating ball type liquid level sensor, comprise water level cylinder, float switch, ball float signal wire, signal processor and control system, described float switch comprises low level float switch, meta float switch and high-order float switch, described low level float switch, meta float switch and high-order float switch are disposed in parallel on water level cylinder inwall up and down, and described float switch is connected successively with ball float signal wire, signal processor machine control system.
In the utility model preferred embodiments, in described float switch, comprise high temperature magnet and tongue tube.
In the utility model preferred embodiments, the spacing between described low level float switch, meta float switch and high-order float switch is 5cm ~ 6cm.
The beneficial effects of the utility model are: a kind of New-type boiler floating ball type liquid level sensor of the utility model, overcome the impact that incrustation scale transmits water level signal, can transmission water level signal promptly and accurately to controller, guarantee boiler use safety, simultaneously easy for installation, price economy material benefit.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of a kind of New-type boiler floating ball type liquid level sensor one of the utility model preferred embodiment;
Fig. 2 is the utility model frame principle;
In accompanying drawing, the mark of each parts is as follows: 1, water level cylinder, and 2, float switch, 3 ball float signal wires, 4, signal processor, 5, control system, 21, low level float switch, 22, meta float switch, 23, high-order float switch.
Embodiment
Be clearly and completely described to the technical scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 to Fig. 2, the utility model embodiment provides following technical scheme.
In one embodiment, a kind of boiler floating ball type liquid level sensor, comprise water level cylinder 1, float switch 2, ball float signal wire 3, signal processor 4 and control system 5, described float switch 2 comprises low level float switch 21, meta float switch 22 and high-order float switch 23, described low level float switch 21, meta float switch 22 and high-order float switch about 23 are disposed in parallel on water level cylinder inwall, and described float switch 2 is connected successively with ball float signal wire 3, signal processor 4 machine control system 5.
In above-mentioned, there are high temperature magnet 25 and tongue tube 24 in described float switch inside, after the ball float on float switch is because of water level rising, tongue tube 24 action because of the magnetic of high temperature magnet 25, signal is given control system 5 by low level float switch 21, meta float switch 22 or high-order float switch 23 output terminal, thus reaches the effect of controlling water level.
In the utility model preferred embodiments, the spacing between described low level float switch 21, meta float switch 22 and high-order float switch 23 is 5cm ~ 6cm.
In sum, a kind of New-type boiler floating ball type liquid level sensor of the utility model, overcomes the impact that incrustation scale transmits water level signal, can transmission water level signal promptly and accurately to controller, guarantee boiler use safety, simultaneously easy for installation, price economy material benefit.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
