Description
Technical field
The present invention relates to liquid level alarms, and in particular to a kind of attachment device of liquid level alarm.
Background technology
Liquid level alarm is also floating-ball level switch, water level controller, liquid-level switch.Liquid level alarm refers to pass through machinery
Formula or the method for magnetic induction carry out the alarm of water level and inspection, can control water simultaneously with audible-visual annunciator etc. or magnetic alarm
The equipment such as pump start or stop, and there are many methods, different according to the different product of selection.Liquid level alarm is widely applied to
Water process, chemical industry, household electrical appliance, machinery equipment, electronics industry.
Common liquid level alarm has the liquid level alarm of cable type and the liquid level alarm of float-ball type
1st, the liquid level alarm of cable type：Cable type liquid level alarm principle is to be encapsulated by microswitch for core element
High-low water level detection is carried out in closed plastic shell, when fluid to be measured reaches operating point, exports high or low liquid level signal,
It is output relay switching signal when liquid level is low to certain position or directly supplies electricity to alarm, so as to fulfill to liquid level
Warning function.Cable type liquid level alarm is not required to floating ball and tongue tube, and without mechanical action, resistant is durable, is not afraid of floating for outside
Object influences, and any angle installation is vertically equipped with certain anti-wave function, and this mode is more practical, resistant, long lifespan, peace
Entirely.There are two types of type of alarms for it：Ultra low water level is alarmed and surcharge water level alarm.
2nd, the liquid level alarm of float-ball type：The floating ball of this alarm has plastics/stainless steel, and annular magnetic is carried by inside
Iron floating ball fluctuates to attract the magnetic reed switch with tongue tube inside pole with water level, sends switch alarm signal,
Can high temperature resistant, acid-alkali-corrosive-resisting, multiple alarm signals, 2 points of a floating ball, 2 floating balls, 4 points, 4 floating balls, 4 points can be done
Function, pole length can do 4 meters.
The mounting structure of existing liquid level alarm is complicated, and installation steps are cumbersome.Existing mounting technique is：First needing
The top for installing the cavity of liquid level alarm is set there are one boss, and casting concrete, and when casting concrete installs several simultaneously
A axis is each perpendicular to the screw rod on ground, is then arranged mounting disc on the guide rod of liquid level alarm again, is provided in mounting disc
Several through holes, then by the guide rod bottom of liquid level alarm through boss and in cavity, the through hole difference in mounting disc is each
Coordinate with a screw rod, be then arranged nut on screw rod again, so as to which liquid level alarm is fixed on boss.
Not only installation steps are cumbersome for the liquid level alarm of this structure, dismounting trouble, and the antirust oil of the thread on screw rod
It paints and its easily comes off, thread is caused to get rusty, is not easy to the dismounting of liquid level alarm.
The content of the invention
Present invention aims at a kind of attachment device of liquid level alarm is provided, solve existing liquid level alarm and not only pacify
