The utility model is combined to move or is closed to replenish the liquid quantity through the induced magnetic reed switch. A control switch of the liquid-level meter does not contact with the liquid and is free from the liquid temperature influence; no leakage of the tightness of a liquid storage container is caused by the liquid-level meter.

Description

Liquid level gauge

The utility model relates to a kind of hydraulic pressure position, particularly relates to a kind of liquid and does not contact with gauge tap, the liquid level gauge of magnetic inductive control.

The switch of prior art liquid level gauge has numerous species, for example limit switch, touch switch, floating switch ... Deng; But which kind of mode no matter, itself all must be installed in its switch body in the tested liquid, and the lead of its connection must pick out outside the container of carrying liquid, and following shortcoming is arranged in use unavoidably:

1. must be installed in the tested liquid owing to gauge tap, may be subjected to etch or influence the sensitivity of induction because of the temperature change of liquid through the long-term character that is soaked in the liquid because of liquid, construct not only that effect is not good and install antiseep additional, and consumption cost on foot.

2. because the lead that connects must pick out outside the container of carrying liquid, make the leakproofness of container be difficult for keeping, causing the situation of leakage, especially pressure vessel more obvious.

The utility model aims to provide a kind of liquid level gauge, it is different from the liquid level gauge of prior art, but the magnetic control system of being applied to principle its objective is such realization: the utility model is mainly by the airtight conduit of a liquid storing barrel, an end, magnetic reed switch, one group of lead, a buoyancy aid, a magnetic element, upper positioning body, once the location division is formed.When combination with not an induced magnetism and the airtight conduit of an end, its sealed end stretches in the container, again with a magnetic reed switch and lead, be installed in the conduit near bottom position, and the buoyancy aid that device one can slide up and down along tube wall outside conduit, install magnetic element on the buoyancy aid, the outer setting element that is provided with in the appropriate location of catheter wall reaches location division down, make buoyancy aid movable in preset range, when liquid level rises or following time falls buoyancy aid and rises thereupon, fall, during to desired location, be installed in the magnetic element on the buoyancy aid, promptly with the interior magnetic reed switch induction of pipe, magnetic reed switch is started carry out deliberate action, form a Switch main body and need not to contact, not the character of liquid body itself with the liquid that will measure, it opens factor affecting such as temperature, close the structure of function, this is the utility model fundamental purpose.

Above-mentioned utility model liquid level gauge, with not an induced magnetism and the airtight conduit of an end, openend connects airtight on the default external tapping in appropriate location on the container, sealed end stretches into and is subjected in the xylometer, magnetic reed switch and lead are installed in the conduit, it is interior for airtight fully to store tested liquid container again, reaches to make to be certain air-tight state in the reservoir vessel, do not leak because of the installing of liquid level gauge causes, this is another purpose of the present utility model.

Below in conjunction with embodiment and accompanying drawing, describe the utility model liquid level gauge in detail.

Fig. 5 is the three-dimensional combination figure of the main structure part of another preferred embodiment of the utility model;

Fig. 6, Fig. 7, Fig. 8 are the buoyancy aid of the utility model one preferred embodiment and the unitized construction stereographic map of magnetic element;

Fig. 9 is the three-dimensional combination figure of the utility model one preferred embodiment.

Can find out that by Fig. 1, Fig. 2, Fig. 3, Fig. 9 the utility model comprises: the conduit 1 of the airtight not induced magnetism of an end (wherein be best with the aldary, also can aluminium alloy or other do not have a material of magnetic induction), magnetic reed switch 2, lead 3, buoyancy aid 4, a magnetic element 5, setting element 6, location division 7, a liquid storing barrel 8, air valve body 9, a liquid level gauge structure that external opening 10 is formed.

By Fig. 1, shown in Figure 3, when combination, openend when the airtight conduit 1 of an end, be installed in the default appropriate location, air valve body 9 bottoms that is fixed on the liquid storing barrel 8, magnetic reed switch 2 and lead 3, be installed in conduit 1 near bottom position, the buoyancy aid 4 that is installed in magnetic element 5 is socketed on the outer wall of conduit 1, the appropriate location of conduit 1 outer wall, be provided with setting element 6 and location division 7, buoyancy aid 4 only can slide up and down along tube wall in setting range, and unlikely getting loose is by Fig. 1, shown in Figure 2, when liquid level 11 liftings, buoyancy aid 4 promptly is being with magnetic element 5 to slide up and down thereupon, drops to when being lower than conduit 1 bottom as liquid level 11, and buoyancy aid 4 promptly is being with magnetic element 5 to descend, and be parked in the position that location division 7 sets, this moment magnetic element 5, promptly with conduit 1 in magnetic reed switch 2 produce induction, make it start external liquid measure and replenish motor.

By shown in Figure 5, when aforementioned magnetic element 5 slips rise to setting element 6, then promptly cut off the power supply of the additional motor of external liquid measure in the conduit 1 after corresponding another magnetic reed switch 2 inductions that are provided with, finish and replenish suitable liquid measure effect; The part of conduit 1 in liquid storing barrel 8 is for airtight fully, magnetic reed switch 2 and lead 3 are because of being installed in conduit 1 inside, so contacting fully with tested liquid, magnetic reed switch 2 and lead 3 can effectively not finish the effect that detects and show liquid level, make magnetic reed switch 2 and lead 3 not liquid body etch or influence its precision because of changes such as fluid temperatures, and because the structures in the liquid storing barrel 8 all are material than the tool rigidity makes and very easily reach airtight effect in the bucket, these characteristics have under the situation of pressure more outstanding in bucket.

Aforementioned magnetic element 5 except that ringwise embedding as shown in Figure 3 or in be embedded outside the state, also can be as shown in Figure 6, form with at least two or two above correspondence positions, be installed on the buoyancy aid 4, its installation position can outer embedding (as shown in Figure 7), also can (as shown in Figure 8) be set embedded mode, and magnetic element 5 quantity are at least more than two, to any corresponding right quantity of the chimeric mode of ring-type.

By shown in Figure 9, the installation position of the utility model liquid level gauge, remove and to be installed on the aperture position that original annex air valve body 9 is provided with in the container (shown in Figure 1), also can add external opening 10 places in other appropriate locations of shell of tank is installed, can reach fully airtight effect equally, and this installing mode demonstrates promptly, the utility model liquid level gauge structure also can be separately set in any liquid level that needs to detect, or fill the post of the effect that liquid measure is replenished switch, be the design of a true tool practicality in fact.

In sum, the utlity model has display switch and lead need not be contacted with tested liquid, can correctly detect, show the liquid level situation, the not etch of liquid body, or, fluid temperature influences its precision because of changing, and can replenish the switch of motor (or other devices) as any external power supply control liquid measure, really reach and make liquid storage container keep airtight, switch must contact with liquid in the prior art and above-mentioned effect has been improved, be vulnerable to etch and easily influence its precision because of fluid temperature changes, the connection that reaches because of lead causes the internal tank leakproofness to be difficult to the fraud of guaranteeing.
