Abstract
The utility model relates to a liquid level instrument which is provided with an isolation chamber 6 communicated with the bottom of a liquid storage container 1 and a liquid level display tube 3, and the lower and bottom part of the display tube 3 dips in the isolation chamber. The display tube 3 is filled with disclosing solution which has the same specific weight and different colour with the working medium, and the lower and bottom part of the display tube is also provided with a flexible liquid bursa 5. The liquid level instrument makes the working medium and the disclosing solution divided completely. When wording, the pressure of the working medium is transmitted to the disclosing solution by the liquid bursa. Consequently, the height of the liquid level in the liquid storage container can be correctly displayed by the liquid level position of the disclosing solution at a displaying pipe column.
Description
The utility model relates to a kind of liquid level gauge that is used to show and observe storage liquid container or device interior liquid level position in industry fields such as medicine, chemical industry and water treatment of power plant.
The liquid level gauge of existing use mostly is the through type liquid level gauge greatly, and promptly the liquid that shows in the liquid level gauge is the actuating medium that flows directly in the storage liquid container.The advantage of through type liquid level gauge be simple in structure, easily manufactured, cost is low, but also have following defective: 1, the liquid level gauge display tube is generally glass tube or organic transparent glass tube, his intensity difference, easily aging, become link the weakest in the tankage, in case damage, to cause leaking in a large number even all of actuating medium, when especially the medium of storing was corrosivity or strong corrosive media in container, its consequence was just even more serious; 2, because the demonstration liquid in the display tube is actuating medium, and they are colourless often or light, like this with regard to occurred liquid level gauge show not obvious, be not easy to problem such as operator's observations, particularly when high position installation or distant surveillance, its display effect is poorer; 3,, be difficult to realize the robotization of controlling for some corrosivity or severe corrosive actuating medium.
The purpose of this utility model is prior art is made improvement, and the isolated liquid level gauge that provides a kind of performance and structure more to become perfect is in order to overcome existing defective in the prior art.
In order to realize the foregoing invention purpose, improvement project of the present utility model is such: the isolated liquid level gauge that is provided has an insulated chamber and a lower bottom part that is communicated with storage liquid container bottom and soaks the liquid level charactron that stand tall and upright in insulated chamber, charge and discharge band look identical with actuating medium proportion but that color is totally different in the display tube and show liquid, the lower bottom part that immerses insulated chamber at display tube also is equiped with a towed flexible barge of making and can freely stretching with flexible material under fluid pressure.During work, in fill the display tube and the liquid capsule that show liquid and make actuating medium and show that liquid separates fully, the liquid capsule passes to demonstration liquid with the pressure of actuating medium, and then driving shows liquid upper and lower lifting in showing tubing string, height in order to liquid level in the correct demonstration storage liquid container helps the operator to finish the mission of observing actuating medium in the container.
The utility model is described in further detail below with reference to accompanying drawing.
Fig. 1 is the structural principle synoptic diagram of this isolated liquid level gauge.
In the embodiment shown in fig. 1, insulated chamber 6 by a short tube 7 with in be filled with actuating medium 2 storage liquid container 1 be communicated with, the bottom have towed flexible barge 5 and in be filled with display tube 3 upright being located in the insulated chamber 6 that the band look shows liquid 4, the two has the manufacturing materials in conjunction with liquid capsule 5 of sealing fully and is decided by the character of actuating medium 2, as: liquid capsule 5 can adopt the rubber type of material of oil resistant, acid, alkalescence to make, when actuating medium 2 was corrosivity or strongly corrosion liquid, liquid capsule 5 can adopt such as the resistant material of teflon class and make.Number in the figure 8 and 9 is a joint flange.
In the use, when actuating medium 2 increases in the storage liquid container 1, working medium pressure in the insulated chamber 6 that communicates with short tube 7 increases, its compressed flexible liquid capsule 5, make its contraction, and the demonstration liquid 4 in the extruding fluid capsule 5 makes it flow to display tube 3 when showing that liquid 4 and the liquid level of storing the actuating medium 2 in the liquid container are contour, pressure equilibrium inside and outside the liquid capsule 5, promptly correctly demonstrate the level condition of liquid in container actuating medium like this by display tube 3, otherwise, actuating medium 2 reduces in the storage liquid container, pressure in the insulated chamber 6 descends, liquid capsule 5 external and internal pressure imbalances, 5 diastoles of liquid capsule, show that liquid 4 is back in the liquid capsule 5, the liquid level in display tube 3 posts is with till liquid level in storing liquid container 1 equates.
Compared with prior art, the utlity model has following characteristics: the mode that 1, liquid level gauge is shown is changed into isolated by through type, making the demonstration liquid in the display tube no longer is to store the interior working media of liquid container but special-purpose demonstration liquid, since the two intercropping thoroughly the isolation, mutually obstructed, even if when display tube breaks or damage, also only only have a small amount of demonstration liquid to be leaked like this, so also made things convenient for maintenance and guaranteed the security that container uses; 2, liquid level shows that liquid is the colored liquid of special preparation, very easily observes for the operator; 3, simple in structure, when realizing Long-distance Control, because showing the liquid non-corrosiveness, can add easily a float, by the conversion of electricity-magnetic signal, the situation of liquid level position is transported to controlling organization.
Claims (3)
