Fig. 1 is the structural drawing of an embodiment of the utility model liquid level control experimental provision.
Embodiment
The utility model is elaborated below in conjunction with accompanying drawing.
With reference to figure 1, illustrate the structural drawing of an embodiment of the utility model liquid level control experimental provision.As shown in the figure, comprise the substrate 100 of vertical placement, and settle water tank 1, water tower 2, water pump 3, valve 4, fluid level measuring gauge 5, signaling interface 6, first pipeline 7, second pipeline 8, index dial 9 and voltage table dial plate 10 on this substrate 100.
Wherein, described water pump 3 is fixed in the interior rear wall of described water tank 1 by screw 31, and the water delivering orifice of this water pump 3 is communicated to the top of described water tower 2 by first pipeline 7; Described first pipeline 7 passes the roof of described water tank 1, and finally is communicated with the top of described water tower 2;
Described fluid level measuring gauge 5 and water tower 2 all are fixed in the end face of described water tank 1, and described fluid level measuring gauge 5 is communicated to the bottom of described water tower 2 by the 3rd pipeline 51; Described water tower 2 is fixed in the end face of described water tank 1 by the gluing ways of connecting, described fluid level measuring gauge 5 by gluing ways of connecting or screw retention in the end face of described water tank 1;
The water inlet of described valve 4 is communicated with the bottom of described water tower, and its water delivering orifice is communicated with described water tank 1 by second pipeline 8; Wherein, described second pipeline 8 passes the roof of described water tank 1, with described water tank internal communication;
Wherein, the back 11 of described water tank 1, just rear wall is fixed on the described substrate 100 by the gluing mode, and then described water tower 2, fluid level measuring gauge 5 be fixed on the described water tank 1, and described valve 4 by with have realized water tower 2 and being connected of water tank 1 the fixing of position.
Need to prove, because described liquid level control experimental provision is to be used for experiment and to need observing, thereby described at least water tank 1 and water tower 2 employing transparent materials, for example organic glass, resin material etc., preferably, described first pipeline 7, second pipeline 8, the 3rd pipeline 51 also all can adopt transparent material, to observe whole experiment more intuitively.
In a preferred embodiment of the present utility model, the inside of described water tower 2 also is provided with liquid level observation tube 21, this liquid level observation tube 21 is thin bar-shaped and hollow, its end sealing and be fixed in the inner top surface of described water tower 2, for example adopt the gluing fixed form, its bottom end opening, and the inner bottom surface of the described water tower 2 of described bottom distance is nearer, with sensitivity with described water tower 2 in and the outer space of described liquid level observation tube 21 constitute linker, and then the interior liquid level of the liquid level in the described liquid level observation tube 21 and described water tower 2 is at same position; Owing to the reason that water in using flows, make that the liquid fluctuating in the water tower 2 more easily detects by an unaided eye, the liquid level in the described liquid level observation tube 21 then fluctuates less, is easier to observe.In addition, described liquid level observation tube 21 cooperates reading with described index dial 9, then can obtain comparatively accurate values.
In addition, also be provided with signaling interface zone 6 on the described substrate 100, be distributed with various switches and interface on it, for example the liquid level output signal interface of fluid level measuring gauge 5, the speed controling signal interface of water pump 3, manual switching interface/switch, start interface/switch, direct supply interface, serial ports and setting value input interface etc., knob is adjusted in the analog input that also comprises pre-set parameter, and it can show reading etc. by voltage table dial plate 10 intuitively.Described liquid level output signal interface is connected with described fluid level measuring gauge or water pump by circuit respectively with the speed controling signal interface.Equally, remain described interface or switch and all is connected with inner circuit yet, owing to be the connection of routine, and inventive point of the present utility model do not lie in this, thereby no longer further sets forth.
In another embodiment of the utility model liquid level control experimental provision, its each ingredient all can be fixed on the described substrate, and then has improved the intensity of whole device.
Need to prove, the position of described water pump 3 also is limited to position embodiment illustrated in fig. 1, it can also be arranged at any position of water tank 1 inside, madial wall etc. for example, even can be placed in the outside of described water tank 1, its water sucking mouth becomes the housing that need pass described water tank 1 and contacts with water by pipeline like this, and its water delivering orifice is communicated in the top of described water tower 2 equally.In addition, described first pipeline 7 there is no concrete qualification with the position of the connector on the top of water tower 2, but in order to observe by index dial 9, the height of so described connector should be higher than the maximum scale of described index dial 9, and this maximum scale can be the maximum scale or the actual maximum scale that uses of portrayal physically.
On the other hand, because described fluid level measuring gauge 5 needs to measure the height of the liquid level in the described water tower 2, thereby it must be communicated with the bottom of described water tower 2, must specifically not limit equally for concrete connection position, but in order to observe by index dial 9, described connection position need be lower than the minimum scale of described index dial 9, and this minimum scale can be the minimum scale or the actual minimum scale that uses of portrayal physically.In like manner, the water inlet of described valve 4 also can be determined with the position that is communicated with of described water tower 2 by reference level meter 5 with the position that is communicated with of described water tower 2.
Described index dial 9 is not limited to be arranged on the left side of described water tower 2, and it can also all have etc. in the right side or the both sides of water tower 2.
It should be noted that because described fluid level measuring gauge 5, water pump 3 and valve 4 are existing equipment, and then it is not described further.
Above disclosed only is a kind of preferred embodiment of the utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalent variations of being done according to the utility model claim still belongs to the scope that the utility model is contained.
