Description
Affiliated technical field
The present invention relates to the liquid-level switch of automatic controlling liquid height in a kind of container.
Background technology
As everyone knows, need automatic controlling liquid height in many containers.Traditional liquid-level switch mainly contains magnetic float-type, cable float-ball type, conductance type, photoelectric type, tuning-fork type, ultrasonic type, condenser type and radio frequency admittance formula etc.The traditional liquid level switch exists following defective:
1, magnetic float-type liquid-level switch can not use in containing the liquid of ferromagnetic impurity, because ferromagnetic impurity absorption can cause the magnetic float not fluctuate with liquid level, and make its Control Failure after on the magnetic float in the liquid.
2, cable float-ball type liquid-level switch volume is big and cost is higher.
3, conductance type liquid-level switch electronic control circuit complexity, out of control easily in the bigger liquid of resistance variations, in the too little liquid of resistance, can short circuit damage.
4, photoelectric liquid-levle switch electronic control circuit complexity needs frequent cleaning glass transparent surface during use, use out of control easily in the liquid that transparency is low and impurity is more.
5, tuning-fork type, ultrasonic type, condenser type and radio frequency admittance formula stuff level switch or liquid-level switch, its electronic control circuit complexity, cost an arm and a leg, and it is out of control easily when outside electromagnetic interference, be mainly used in the control of container endoparticle height of materials position, and the control of liquid height under the particular surroundings.
Summary of the invention
The object of the present invention is to provide a kind of wide adaptability, safe and reliable, safeguard simple, volume is less, cost is lower, long service life, electronic control circuit are fairly simple, the not influence of ferromagnetic impurity in the liquid body, not the liquid body resistance variations influence, not the liquid body transparency influence, be not subjected to the liquid-level switch of outside electromagnetic interference.For reaching this purpose, technical scheme of the present invention is as follows:
A kind of switch is assembled by nut, pole, knit nylon flexible cord, spiral electric wire, heat-shrinkable T bush, float, ball switch (or mercoid switch), protective cover and mount pad.
Described switch is by the installing hole of mount pad, when being installed in a certain liquid height position of required control in the container, rising or reduction with the liquid in container height, liquid passes through the last filtering holes and the inflow of following filtering holes of protective cover or flows out in the protective cover of switch, float is under the effect of liquid buoyancy, rise and rotation decline around pole rotation: when the float rotation rises to certain angle, the ball switch in the float (or mercoid switch) closure; When the float rotation dropped to certain angle, the ball switch in the float (or mercoid switch) disconnected.Closed and disconnection control driven by power makes the inflow and the discharge of liquid in container by the ball switch in the float (or mercoid switch), reaches the requirement of control liquid in container height.When a plurality of switch is installed in the differing heights position in the container, can reach the purpose of a plurality of liquid heights position in the control container.
Described switch is by pack into the through hole of mount pad of pole, through being threaded of pole and nut, with strut fixation on mount pad; Cooperating of four claws of protective cover by its four bayonet sockets and mount pad, mount pad and protective cover are assembled into one; The knit nylon flexible cord passes from the threaded hole of spiral electric wire spiral part, the two ends colligation of knit nylon flexible cord and spiral electric wire spiral part; Spiral electric wire short leg end is connected with the lead-in wire soldering of ball switch (or mercoid switch), and heat-shrinkable T bush is sleeved on the wire bonds place of spiral electric wire and ball switch (or mercoid switch); The two circle spirals of spiral electric wire spiral part short leg end and the end of knit nylon flexible cord, by the fluid sealant in the float counterbore, fixing seal is bonded in the top of float counterbore together, and ball switch (or mercoid switch) is sealed in the bottom of float counterbore; Spiral electric wire long lead end is drawn from the closed hole and the through wires hole of pole, the two circle spirals of spiral electric wire spiral part long lead end and the end of knit nylon flexible cord, and by the fluid sealant in the pole closed hole, fixing seal is bonded in the closed hole of pole together.After the switch assembling, float can freely rotate up and down in the space between protective cover and the mount pad.
The length of knit nylon flexible cord colligation is identical with the drift of spiral electric wire spiral part threaded hole in the described switch, be used to support the weight of float and spiral electric wire spiral part, the fixing length of spiral electric wire spiral part is to guarantee the useful life of spiral electric wire.
Ball switch in the described switch (or mercoid switch) fixing seal guarantees that in the bottom of the counterbore of float the work of ball switch (or mercoid switch) is not subjected to external influence.
The protective cover of described switch is provided with filtering holes and following filtering holes on several, is used for the foreign material of filter liquide, to eliminate the influence that foreign material float to float, guarantees that switch can use in more dirty liquid.
Described switch can be cancelled the protective cover and the mount pad of switch as using in cleaner liquid.
The present invention compared with prior art has following advantage:
One, ball switch (or mercoid switch) is enclosed in the float, and its break-make is not subjected to external influence.
Two, ball switch (or mercoid switch) is a kind of mechanical type light current contact switch, and product reliable operation, long service life, electronic control circuit more simply, are not subjected to the interference of external electromagnetic, not influence, not influence, the not influence of liquid body transparency of liquid body resistance variations of ferromagnetic impurity in the liquid body.
Three, the part that contacts with liquid of switch is engineering plastics or rubber, all can use for a long time in inoic acid caustic corrosion liquid and the oil-based liquid.
Four, simple in structure and cost is lower.
