Unless otherwise defined, all of technologies and scientific terms used here by the article is led with belonging to technology of the present utility model
The implication that the technical staff in domain is generally understood that is identical.It is simply in term used in the description of the present utility model herein
The purpose of description specific embodiment, it is not intended that in limitation the utility model.Term as used herein " and/or " include
The arbitrary and all combination of one or more related Listed Items.
Fig. 1 is the structural representation of the tank level control system of oil storage tank 100 provided by the utility model.With reference to figure 1, this practicality
A kind of new tank level control system of oil storage tank 100 of offer.The tank level control system of oil storage tank 100 includes oil storage tank 100 and oil transportation
Pipeline 200, the oil pipeline 200 is to the transporting oil of oil storage tank 100.The system also includes：On-off valve 400, oil transfer pump
500th, high report tuning fork 300 and programmable logic controller (PLC) (hereinafter referred to as controller).Wherein, the on-off valve 400 and described
Oil transfer pump 500 is installed on the oil pipeline 200, and height report tuning fork 300 is arranged at the side of the oil storage tank 100 so that the height
The fork of report tuning fork 300 is in inside the oil storage tank 100, and programmable logic controller (PLC) electrically connects with the high report tuning fork 300
To receive the electric signal of the high report tuning fork 300, and electrically connected with the on-off valve 400 and the oil transfer pump 500 with basis
The electric signal controls the oil transfer pump 500 to close and the delay scheduled time of on-off valve 400 disconnection.
For height report tuning fork 300 when not with fluid level contacts, the signal exported to controller is 1, defeated when with fluid level contacts
The signal gone out is 0.Height report tuning fork 300 is arranged at the safe altitude opening position of the side of oil storage tank 100, is installed additional in oil storage tank 100
During oil product, the progressively lifting of oil product liquid level, when the liquid level of oil product is reached at the high place of report tuning fork 300, oil is represented
Product amount has reached standard, if oil product liquid level continues lifting, will exceed oil product safe range, produce negative consequence.
Now, high report tuning fork 300 contacts with oil product, and the signal that height report tuning fork 300 is sent to controller is changed into 0 from 1 immediately,
Controller controls oil transfer pump 500 to close according to the control logic of internal preset, and oil transfer pump 500 stops pump oil, delay scheduled time
(being usually after several seconds) afterwards, control on-off valve 400 disconnects, i.e., on-off valve 400 disconnects the connection of oil pipeline 200.
Conversely, in the installation process of oil product, oil product does not contact with height report tuning fork 300, and height report tuning fork 300 is defeated to controller
The signal gone out is 1, closes the chain control of delivery pump and on-off valve 400, and delivery pump continues pump oil, and on-off valve 400 connects oil transportation
Pipeline 200, oil storage tank 100 continue to install oil product additional.
Thus, the chain control by oil transfer pump 500 and on-off valve 400 in circuit, safe liquid is reached in oil storage tank 100
The very first time sends instruction to oil transfer pump 500 and on-off valve 400 during position, it is ensured that the liquid level of oil storage tank 100 is in safe model
Within enclosing, and oil transfer pump 500 and on-off valve 400 act in the interval scheduled time, it is thus achieved that quick response, effectively keeps away
Exempt from roof fall, avoid economic loss, avoid being unfavorable for the event of environmental protection, be effectively prevented from water hammer, ensure oil pipeline
200 safety, the storage satety of oil depot is improved, also saves human resources.
Preferably, the scheduled time is the scope between 3 seconds to 5 seconds.Reasonably set what the delay of on-off valve 400 disconnected
Time, water hammer can be effectively avoided, that is, avoid flow rate of liquid in pipeline from drastically changing and cause pressure to fluctuate widely,
Improve storage satety.
It is further preferable that the scheduled time is 4 seconds.
Above-mentioned on-off valve 400 is preferably pneumatic on-off valve 400, in this way, when receiving the control instruction of control, action is more
For sensitivity, it is better able to disconnect oil pipeline 200 in time, ensures promptness.
Fig. 2 is the structure diagram of the oil storage tank 100 in Fig. 1.With reference to figure 2, in a preferred embodiment, oil storage tank
100 include body 101 and are convexly equipped in the protuberance 102 of the side wall of the body 101, protuberance 102 and the liquid of body 101
Connection, the protuberance 102 protrude the preset distance of body 101 to accommodate the high report tuning fork 300 completely in the horizontal direction
Fork.
The body 101 of oil storage tank 100 is used to accommodate oil product, protuberance 102 and the fluid connection of body 101, thus protuberance
Also oil product is accommodated in 102.The length of protuberance 102 in the horizontal direction is enough the fork for accommodating high report tuning fork 300, so can
The high report tuning fork 300 for being enough accurately perceives the liquid level in oil storage tank 100 so as to start above-mentioned chain control, can also avoid
The fork of height report tuning fork 300 is extend into the body 101 of oil storage tank 100, so as to ensure that the safety of the floating plate of oil storage tank 100 rises
Drop.
Preferably, the protuberance 102 is welded in the body 101, and the high report tuning fork 300 is threadedly connected to described convex
Go out portion 102, the junction of the high report tuning fork 300 and the protuberance 102 is provided with seal washer.
In this embodiment, the connected mode of welding and seal washer can be it is effectively guaranteed that the connection of whole system be close
Feng Xing.
Preferably, the protuberance 102 forms general cylindrical shape space.Cylindrical space is more easy to shape compared with other shapes space
Into also advantageously in the easy of processing technology.It is of course also possible to form the space of other shapes, such as hexahedral space.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, the scope that this specification is recorded all is considered to be.
Embodiment described above only expresses several embodiments of the present utility model, and its description is more specific and detailed,
But therefore it can not be interpreted as the limitation to utility model patent scope.It should be pointed out that the common skill for this area
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
