Description
Technical field
The present invention relates to level sensing control instrument field, be specifically related to a kind of ball float inductor.
Background technology
Ball float inductor mainly acts on the rise or decline that control liquid level, such as pour water in pond with an immersible pump, but need to allow water rate control in pond in certain water level range, just need this time to carry out controlling water level with ball float inductor, reach and neither make the too low object that also can not make outside water spilling pond of pond middle water level.
Ball float inductor is a kind of very conventional liquid-level switch product, and its maximum advantage does not have complicated circuit, and can not be subject to other environmental factor interference, the matter that only needs a person with the qualifications of a general chooses, and it can use under the liquid of any character, temperature, pressure.
The ball float inductor of current domestic production is inserted when using in the more liquid of impurity all unstable; often there will be the stuck motionless phenomenon of ball float, thus exceeded the water level of the highest permission or liquid when causing liquid to increase still can not action to ball float after lowest order.Time in the cutting liquid bath particularly ball float being placed on industrial processes, ball float is easy to be blocked by foreign matter (as iron filings, aluminium bits), ball float is moved up and down and has some setbacks, cause ball float inductor to detect and lost efficacy, need frequent manual maintenance, have a strong impact on production efficiency.
Summary of the invention
For the problems referred to above, the invention provides a kind of efficient ball float inductor, be particularly useful for CNC high water tank and automatically detect, effectively can solve the stuck problem of ball float.
A kind of ball float inductor, comprises ball float, piston rod and outer casing; Described outer casing is provided with cavity, and described piston rod one end connects ball float, and the other end is positioned at the cavity of outer casing; Be provided with at least two inductors along cavity axial distribution in described cavity, the piston rod being positioned at cavity is provided with the touch control component that can trigger inductor, and described ball float drives piston rod and touch control component reciprocating motion along cavity axially reciprocating; The cavity oral area of described outer casing is provided with sealing ring, and piston rod is set on sealing ring.
Preferably, described inductor is magnetic switch; Described touch control component is sheathed annular magnet on the piston rod.
Further, ball float inductor also comprises mounting panel, and described mounting panel fixes the oral area of capping outer casing cavity, and mounting panel is provided with through hole, and described sealing ring is arranged in through hole.
Preferably, described outer casing comprises the outer cover of tubulose and is arranged on the cover plate at outer cover top.
Preferably, the outer wall of described outer cover is axially provided with fixing rib along outer cover, and the fixing rib end that described top cover is corresponding with it is spirally connected; The fixing rib end that described mounting panel is corresponding with it is spirally connected.
The operation principle of ball float inductor is, will one or more magnetic switch (tongue tube) be set in nonmagnetic metal or plastic pipe according to actual needs, again annular magnet is fixed on pipe inner piston rod, piston rod connects ball float, when ball float fluctuates within the specific limits, piston rod and annular magnet is driven to move up and down, annular magnet triggers magnetic switch when moving to the correspondence position of magnetic switch in pipe, triggering signal is sent to main control unit by magnetic switch, main control unit controls water pump again according to the triggering signal of the different magnetic switch feedbacks received to start to add water or stop to add water in tank, thus play the function of ball float inductor sensed water level liquid level.
This ball float inductor low cost of manufacture, efficient, energy-saving and environmental protection, move up and down smooth and easy and respond to sensitive, non-maintaining.The piston rod of ball float inductor rises and in decline process, because piston rod is arranged with sealing ring, so the problem not having foreign material seized piston bar and cause ball float inductor malfunctioning, is applicable in polymictic liquid, responds to sensitive, zero failure.
