Abstract
The utility model relates to a non-sliding contact point type oil tank liquid level device which is composed of a plurality of floating balls connected to a chain bar in a sleeved mode, and each floating ball is provided with a magnet, magnetic induction switches are arranged in positions, corresponding to the floating balls, in the chain bar, and each magnetic induction switch is electrically connected with a conversion device. According to the non-sliding contact point type oil tank liquid level device, by the adoption of a magnetic floater type liquid level device, under the premises that the requirement for functions of an original automobile oil tank liquid level device is met and an original automobile liquid level control circuit is not changed, the problems that a contact point makes contact with liquid so as to generate electrolytic oxidation, service life is shortened and unsafe factors exist are solved. For example, methanol gasoline, ethanol gasoline, methanol, ethyl alcohol and the like are used for replacing the fuel of gasoline which performs oxidation corrosion on a traditional liquid level contact point. The non-sliding contact point type oil tank liquid level device can be used for liquid level detection besides an automobile oil tank, convenience is wide, controlling is easy, precision is high, use cost is low, stability is good, and liquid level measuring of other liquid (including conducting liquid and corrosive liquid) can also be achieved.
Description
Technical field
The utility model relates to the liquid level meter for motor vehicle oil tank, is specifically related to non-sliding contact formula oil tank liquid level device.
Background technology
The main effect of oil tank liquid level device is to measure liquid level and control height of liquid level, realize the signal is far passed function, concrete function is according to kind and the Configuration of liquid level meter, automotive oil tank sliding contact formula liquid level meter for example, it is installed in fuel tank internal, and Electrolysis often appears in the meeting generation current but contact work is slided, contact serviceable life is reduced in the oxidation contact.The generation of problems has been avoided in the appearance of magnetic-float type liquid level meter, and the magnetic-float type liquid level meter is take magnetic float as sensing element, and by magnetic float and the coupling that shows magnetic in the vitta, reflects the measurement instrument at tested liquid level or interface.It is eye-catching that the magnetic-float type liquid level meter has intuitive display, easy installation and reliable, and maintenance is little, and the advantage that maintenance cost is low is glass tube, the upgraded product of glass plate liquid level meter.Can be widely used in oil, chemical industry, the power station, pharmacy, metallurgy, shipping industry, the tank of the industries such as water/wastewater treatment, groove, the liquid level of the containers such as case detects.
The utility model content
In order to overcome defective of the prior art, the utility model provides non-sliding contact formula oil tank liquid level device, has solved contact work slip generation current, and the problem of oxidation contact has prolonged serviceable life of contact.
The utility model provides by a plurality of ball floats that are socketed on the chain bar and has consisted of, and is equipped with magnet in each ball float; In the chain bar of the relevant position of described each ball float, magnetic induction switch is installed all, and each magnetic induction switch and conversion equipment electrically connect.
Preferably, described ball float and chain bar are slidingly connected.
Preferably, described chain bar vertically is installed in the fuel tank, and the length of chain bar and the fuel tank degree of depth are basically identical.
Preferably, described conversion equipment is installed in chain bar outside.
Preferably, described magnet is fixed on the ball float middle part.
The beneficial effects of the utility model are:
The utility model is by adopting the magnetic-float type liquid level meter, at the function needs that satisfy original automotive oil tank liquid level meter with do not change under the prerequisite of former automobile liquid level meter control circuit, solve the oxidation that produces electrolysis of contact contact liq, reduced the unsafe factor of serviceable life and existence.
But range of application and usability are wider stronger, solve automobile in Future New Energy Source is promoted the use of, and the contact oxidation corrosion phenomenon because using the traditional liquid level device to occur reduces its serviceable life, thus the potential safety hazard of avoiding.Such as use methanol gasoline, ethanol petrol, methyl alcohol, ethanol etc. replace gasoline fuel and to the oxidation corrosion of traditional liquid level device contact.
Can be applicable to except the automobile fuel tank liquid level and detect, convenience is wide, and control is simple, and is accurately high, and the low and good stability of use cost can also be realized the level gauging of other liquid (contain conducting liquid, liquid is corrosive).
