Description
Technical field
The utility model relates to the liquid height detecting element in a kind of tank mounting being applied to the system such as hydraulic pressure, lubrication, is specifically related to a kind of liquid level gauge by multiple elements combination.
Background technology
A fuel tank is all provided with in the system such as hydraulic pressure, lubrication, for the hydraulic pressure wet goods medium that splendid attire hydraulic system uses, because the hydraulic oil in fuel tank can because to leak or replenisher force feed or water enter in fuel tank and causes liquid level to change, therefore, fuel tank is all provided with can the liquid level gauge of electric sender, whether is used for detecting the height of liquid level in normal range.The structural principle of existing conventional liquid level gauge is all by the magnetic attraction tongue tube with magnetic float, close loop, thus sends electric signal.This liquid level gauge is applicable in common environment, but in the occasion that some magnetic fields are larger, as potroom, just can not be suitable for, because the magnetic field in environment can reach 200GAS, just can automatically tongue tube adhesive, because tongue tube adhesive is not realized by magnetic float, can error signal be caused like this, the truth of liquid level can not be reflected.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of liquid level gauge be applicable in the environment of magnetic field induction.
The utility model solves the technical scheme that its technical matters adopts: a kind of anti-magnetic-type liquid level gauge, be made up of electrical connector, erection joint, tongue tube sleeve pipe, antimagnetic sleeve pipe, tongue tube, electrical wiring, magnetic float, axle elastic washer, described electrical connector one end and tongue tube complete electrical connection by electrical wiring, and the other end is connected with external electrical; Described erection joint is provided with at center can not the through hole of magnetized tongue tube sleeve pipe for installing, described tongue tube sleeve pipe one end open, and the other end is closed, and one end of opening is fixedly mounted in the through hole of erection joint; In described tongue tube sleeve pipe, one or more tongue tubes are installed, each tongue tube correspondence arranges a magnetic float, described magnetic float is annular, be placed on tongue tube sleeve pipe, respectively establish an axle elastic washer up and down at described magnetic float, described axle elastic washer elasticity is clamped on tongue tube sleeve pipe; Described erection joint fixedly mounts an antimagnetic sleeve pipe, and tongue tube sleeve pipe and magnetic float are encapsulated by described antimagnetic sleeve pipe, are provided with the aperture for being communicated with outside fluid at described antimagnetic sleeve bottom.
As the improvement of technique scheme, be also provided with installation crossover sub, electrical connector and erection joint are threaded connection by described installation crossover sub.
As the improvement of technique scheme, the material of described tongue tube sleeve pipe is that copper or stainless steel etc. can not magnetized materials.The material of described antimagnetic sleeve pipe is the magnetizable material such as steel or iron.
The beneficial effects of the utility model are: because tongue tube and magnetic float are closed by antimagnetic sleeve pipe of the present utility model, and itself makes for magnetisable material, a shielding space is formed like this in antimagnetic sleeve pipe, make the magnetic field of outside can not carry out adhesive to the tongue tube of the inside, the work of liquid level gauge can not be affected, therefore, the utility model can be applicable in the environment of magnetic field induction.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic diagram that the utility model is arranged in mailbox.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
With reference to Fig. 1, Fig. 2, a kind of anti-magnetic-type liquid level gauge, is made up of electrical connector 1, erection joint 3, tongue tube sleeve pipe 4, antimagnetic sleeve pipe 5, tongue tube 6, electrical wiring 7, magnetic float 8, axle elastic washer 9.Electrical connector 1 one end and tongue tube 6 complete electrical connection by electrical wiring 7, and the other end is connected with external electrical.Between electrical connector 1 and erection joint 3, be provided with crossover sub 2, electrical connector 1 and erection joint 3 are threaded connection by crossover sub 2.Erection joint 3 is provided with through hole at center, and for installing tongue tube sleeve pipe 4, tongue tube sleeve pipe 4 can not be made by magnetized material by copper or stainless steel etc., its one end open, and the other end is closed, and one end of opening is fixedly mounted in the through hole of erection joint 3.One or more tongue tubes 6 are installed in tongue tube sleeve pipe 4, the present embodiment is two, each tongue tube 6 correspondence arranges a magnetic float 8, magnetic float 8 is annular, be placed on tongue tube sleeve pipe 4, respectively establish an axle elastic washer 9 up and down at magnetic float 8, axle elastic washer 9 elasticity is clamped on tongue tube sleeve pipe 4.Erection joint 3 fixedly mounts an antimagnetic sleeve pipe 5, and antimagnetic sleeve pipe 5 is made by the magnetizable material such as steel or iron, and tongue tube sleeve pipe 4 and magnetic float 8 are encapsulated by it, bottom antimagnetic sleeve pipe 5, be provided with aperture, for being communicated with outside fluid.
Erection joint 3 is connected with the outer erection joint 10 of liquid level gauge by screw thread, and outer erection joint is directly welded on the casing of mailbox 11, completes the installation of liquid level gauge and mailbox like this.
Principle of work of the present utility model is: the proportion of magnetic float is less than the proportion of fluid medium, can float on above fluid medium, and along with the rising of liquid level or decline.If when magnetic float rises to position (i.e. the desired location of tongue tube) of high point or superelevation point, the radial suction that magnetic float produces is tongue tube adhesive, circuit closed electrically, send high point or superelevation point signal, if liquid level continues to rise, define the position of the rising of magnetic float due to axle elastic washer, magnetic float continues can to tongue tube adhesive, holding signal; If when magnetic float drops to position (i.e. the desired location of tongue tube) of low spot or ultralow point, the radial suction that magnetic float produces is tongue tube adhesive, circuit closed electrically, send low spot or ultralow some signal, if liquid level continues to decline, because axle elastic washer defines magnetic float position down, magnetic float continues can to tongue tube adhesive, holding signal.Because tongue tube and magnetic float are closed by antimagnetic sleeve pipe, and itself makes for magnetisable material, a shielding space is formed like this in antimagnetic sleeve pipe, make the magnetic field of outside can not carry out adhesive to the tongue tube of the inside, the work of liquid level gauge can not be affected, therefore, can be applicable in the environment of magnetic field induction.
Although describe embodiment of the present utility model by reference to the accompanying drawings above, those skilled in the art can make various distortion or amendment within the scope of the appended claims.
