Abstract

The utility model discloses a magnetic liquid level gauge, composed of a sleeve, a display circuit in the sleeve, a floating drum and a permanence magnetic block in the floating drum. The magnetic liquid level gauge is characterized in that the floating drum is fixed at the outer wall of the sleeve by a support frame, and the floating drum has relatively big wall thickness according to the need of bearing pressure. The floating drum can turn over under the buoyancy, and the liquid level display circuit realizes the on-off through the permanent magnetic block in the floating drum. The utility model has the advantage that the magnetic liquid level gauge can bear relatively big pressure and is suitable for the liquid level display of liquid which has many impurities and is highly viscous.

Description

A kind of magnetic fluid level gauge

The utility model relates to a kind of liquid level display device, particularly a kind of magnetic floating ball lever meter.

Existing magnetic fluid level gauge kind is more; a kind of floating ball lever meter commonly used is work like this: the sleeve pipe of protection display circuit stretches under the liquid level; sleeve pipe is provided with one outward and the ball float of permanent collision block is housed with sleeve outer wall motion in lower edge on the liquid level; the impact force of magnetic patch acts on the display circuit in the sleeve pipe and shows liquid level; this liquid level gauge requires sleeve outer wall highly polished; the verticality that sleeve pipe is installed requires high; it is few to be used to measure impurity content; no suspended substance; the liquid that viscosity is little; and the deadweight that requires ball float is less than the buoyancy that is produced; usually can only do the ball float wall thinner, thereby can't bear higher pressure in the container.

The purpose of this utility model is to provide a kind of can be applicable to middle and high pressure vessel, and especially impurity is many, and suspension is many, and the magnetic fluid level gauge that the liquid level of the liquid that viscosity is big shows wishes that it has the advantage that making is easy, the installation accuracy requirement is low.

For solving above-mentioned task, scheme of the present utility model is: be provided with show circuit in the closed casing of liquid level display segment in stretching into container, at sleeve pipe 1 outer wall one support 13 is arranged, be fixed with several right cylinder parallel sealing floating drums 6 on it with casing axis, this floating drum 6 can be made thicker wall thickness according to the pressure-bearing demand side, an end is equipped with permanent magnet 8 near sleeve pipe one side in this floating drum 6, by being fixed between support 3 and the sleeve pipe 1 perpendicular to bolster 9 axis and that it is fixedly connected.These bolster 9 present positions with respect to the axis focus point of floating drum 6 have one section near permanent magnet 8 ends and can guarantee that floating drum produces the eccentric distance that overturns under buoyancy function.

Described show circuit is in parallel for to be set to a tongue tube magnetic switch (12) of connecting with resistance 13 corresponding to each permanent magnet 8 position between a plurality of resistance, is two end points output states.

Described show circuit is that the circuit of corresponding each magnetic patch (8) all is independent loops, is the multi-endpoint output state.

The quantity of described floating drum (6) is at least more than two.

The utility model has overcome the ball float of traditional magnetic floating ball lever meter must be with the defective of liquid surface lifting, floating drum is fixed on the sleeve pipe, thereby accuracy requirement reduces greatly to the environment for use installation and processing to make magnetic ball float meter, because being far smaller than, the required buoyancy of floating drum generation deflection overcomes the required buoyancy of deadweight, unrestricted to the ball float oneself requirement, according to the pressure-bearing needs, can have bigger wall thickness.Be applicable to that pressure is higher, impurity content is many, and the liquid level that viscosity is big shows.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the utility model one-piece construction synoptic diagram;

Fig. 2 is the utility model partial enlarged drawing;

Fig. 3 is the user mode figure of floating drum.

Each member partly is as follows among the figure: 1, sleeve pipe, 2, flange, 3, support, 4, the circle open-work, 5, axle sleeve, 6, floating drum, 7, bearing, 8, permanent magnet, 9, bolster, 10, screw, 11, block, 12, magnetic switch, 13, resistance, 14, connect lead.

Sleeve pipe 1 is as shown in Figure 1 linked by flange 2 and container, frame set 3 has been fixedly connected on the sleeve outer wall, with have the round open-work 4 corresponding on one side of the parallel sleeve pipe 1 of support 3 with floating drum 6, be fixed with axle sleeve 5 on the sleeve outer wall of these circle open-work 4 correspondences, an end is near sleeve pipe one side in the described cylindrical seal floating drum 6, if one by a fixing permanent magnet 8 of bearing 7, floating drum 6 holds axle 9 changes by change and holds, and there is one section close permanent magnet 8 one end these bolster 9 present positions and can guarantees that floating drum produces the eccentric distance of upset under buoyancy with respect to the axis focus point of floating drum 6.Floating drum 6 holds axle 9 supportings by change, bolster 9 two ends place axle sleeve center pit and circle open-work 4 respectively, have by screw 10 in arranged outside and to be fixed in block 11 on the support corresponding to each circle open-work 4, be provided with a dry-reed magnetic switch 12 in sleeve pipe 1 inside corresponding to each permanent magnet 8 position, this dry-reed magnetic switch is parallel in the show circuit by being connected lead 14 with resistance 13, this loop also can be adopted corresponding to each floating drum 6 a single-circuit mode is set, the quantity of floating drum 6 also can require increase and decrease according to measuring accuracy, is generally more than 2.

The utility model is work like this: when liquid level rises, floating drum is dipped in and is subjected to buoyancy in the liquid and produces upset, magnetic switch 12 produces action, described resistance 13 promptly is switched on or switched off with circuit, when liquid level descended, floating drum was in action of gravity reversion position next time, and magnetic switch 12 is also corresponding to be resetted, the corresponding variation that resistance value occurs of circuit, this changing value reflects the situation of change of liquid level by display device.
