Technical field
The utility model relates to liquid level sensor, particularly relates to a kind of floating ball type liquid level sensor of long service life.
Background technology
Liquid level sensor is a kind of pressure transducer measuring liquid level, mainly contains float-type liquid level sensor, floating ball type liquid level sensor and static pressure type liquid level sensor.Floating ball type liquid level sensor is primarily of the parts such as ball float, magnet and tongue tube composition, and this kind of liquid level sensor utilizes ball float synchronously to change along with liquid level, and the displacement of ball float band moving magnet, controls the switch of tongue tube further by the displacement of magnet.Existing floating ball type liquid level sensor is owing to will be placed in water tank, usually adopt sealing gasket to carry out water-proofing treatment to the cavity of accommodating tongue tube, but the time one is long, the air inside cavity can be oxidized the pin of tongue tube, make whole product lose function, reduce its serviceable life.
Utility model content
For the problems referred to above that prior art exists, the purpose of this utility model is to provide a kind of floating ball type liquid level sensor with good waterproofing effect and long service life.
For achieving the above object, the utility model adopts following technical scheme: a kind of floating ball type liquid level sensor of long service life, comprises the body of rod, magnetic floating block and control terminal; The described body of rod is the cylindrical structural with hollow cavity, and the bottom of the body of rod is provided with spacing back-up ring, and the top of the body of rod is provided with limit mounting structure; Described limit mounting structure comprises the installation portion of horizontally set and the vertical limiting section arranged; Described installation portion is provided with mounting hole; Be provided with tongue tube in described hollow cavity, described tongue tube is connected with the control terminal be positioned at outside the body of rod by wire, and in described hollow cavity, remaining space is filled with waterproof and sealing material; Be arranged with PVC sleeve pipe outside described wire, the bottom of PVC sleeve pipe abuts with the top of the body of rod, and the top of PVC sleeve pipe abuts with the ligament be connected to outside wire; Described magnetic floating block adopts corrosion resistant plastic material to make, and inside is provided with magnetisable material, and magnetic floating block can be set in outside the body of rod relative sliding, and the part between body of rod upper limit back-up ring and limit mounting structure.
As optimization, as optimization, described magnetisable material is magnet.
Relative to prior art, the utility model tool has the following advantages: the floating ball type liquid level sensor of the long service life that the utility model provides carries out the remaining space of filling the hollow cavity that tongue tube is housed by waterproof and sealing material, thus reach good waterproof effect, also effectively prevent the pin of the air oxidation tongue tube inside hollow cavity simultaneously, extend the serviceable life of tongue tube.
Accompanying drawing explanation
Fig. 1 is the cut-open view of the floating ball type liquid level sensor of long service life.
In figure, the body of rod 10, spacing back-up ring 11, installation portion 12a, limiting section 12b, mounting hole 12c, tongue tube 13, wire 14, PVC sleeve pipe 14a, ligament 14b; Magnetic floating block 20, control terminal 30.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
In description of the present utility model, it will be appreciated that, orientation or the position relationship of the instruction such as term " interior ", " outward ", " top ", " low " are based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
See Fig. 1, a kind of floating ball type liquid level sensor of long service life, comprises the body of rod 10, magnetic floating block 20 and control terminal 30.
The body of rod 10 is for having the cylindrical structural of hollow cavity, the bottom of the body of rod 10 is provided with spacing back-up ring 11, the top of the body of rod 10 is provided with limit mounting structure, limit mounting structure comprises the installation portion 12a of horizontally set and the vertical limiting section 12b arranged, installation portion 12a is provided with mounting hole 12c, conveniently installs floating ball type liquid level sensor, when specifically implementing, limit mounting structure can be one-body molded with the body of rod, convenient processing and installation.The setting of spacing back-up ring and limit mounting structure, effectively limits the working range of liquid level sensor, and placement magnetic floating block and the body of rod depart from.
Tongue tube 13 is provided with in hollow cavity, tongue tube 13 is connected with the control terminal 30 be positioned at outside the body of rod 10 by wire 14, in hollow cavity, remaining space is filled with waterproof and sealing material, reach waterproof effect, also effectively prevent the pin of the air oxidation tongue tube inside cavity simultaneously, extend the serviceable life of tongue tube.
Magnetic floating block 20 can be set in outside the body of rod 10 relative sliding, and the part between the body of rod 10 upper limit back-up ring 11 and limit mounting structure.Magnetic floating block 20 adopts corrosion resistant plastic material to make, and inside is provided with magnetisable material, and magnetisable material is preferably magnet.
As optimization, scribble corrosion-resistant outside wire 14, and the diaphragm of insulation, available protecting wire.PVC sleeve pipe 14a is arranged with outside wire 14, can available protecting wire further, the bottom of PVC sleeve pipe 14a abuts with the top of the body of rod 10, and the top of PVC sleeve pipe 14a abuts with the ligament 14b be connected to outside wire 14, thus reaches spacing object.
The principle of work of the floating ball type liquid level sensor of the long service life that the utility model provides:
Whole liquid level sensor is suspended in the container of liquid level to be measured, magnetic floating block is deep in liquid completely, the buoyancy that magnetic floating block is subject in liquid changes, thus move on the body of rod, because the change of magnetic induction density causes the switch activity of tongue tube in its moving process, the electric signal that tongue tube activity produces to control terminal, thus can to judge in container that liquid level changes by wire transmission.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
