Description

The trigger mechanism of water level switch
Technical field
The utility model relates to the water level control field, relates in particular to the improvement of the trigger mechanism of water level switch.
Background technology
At present, on the market switch used from move mostly can be divided in form following several: 1), early stage pullswitch; 2), be contained in the tumbler switch on wall; 3), operating switch, i.e. isolating switch; 4), the touching switch of push button, 5), rotary switch, or switch.Its effect normally forms a kind of often opening or normally closed state.
And, at the water level control field, generally in the light current state, the concrete application mode of water level switch generally has following several:
1), float type level switch (immersion), its electrical wiring is immersed in water all the time, its safety coefficient is lower; Simultaneously, electric wire drifts about with current, therefore, stirring machine can't be installed in pond; Secondly, the heavy ball requirement level fluctuation in ball float can not be too large; In addition, due to the electric wire own wt, require the range of control can not be too large.
2), ultrasonic level gage (liquid above formula), need external power supply, linear quadratic control and running environment preferably, have uneconomical, to user's the high defect that requires.
3), pressure switch (liquid above formula), set more loaded down with trivial detailsly, need to carry out linear quadratic control.
4), electric pole type level switch (immersion), need secondary power supply and linear quadratic control, limit, in water, is absolutely unsafe during use;
5), the sweet reed pipe switch of magnetic (immersion), be divided into Direct Action Type and convertible, wherein under water it doesn't matter for magnet, but electric wire need to be received sweet reed pipe, safety coefficient is low, also higher to the requirement of environment.
For above-mentioned some, how to make water level switch can evade above defect becomes those skilled in the art's technical matters urgently to be resolved hurrily simultaneously.To this, State Bureau has announced the document that a by name " elastic force type fluid level controller ", application number are " 99202140.5 " on June 14th, 2000, in this case when low-water level by the leave behind afterbody of shift bar of outstanding son and the sub deadweight that suspends, make the reservoir water inlet; After water level rises, outstanding son and the son that suspends shed the pulling force to shift bar under the effect of buoyancy, make shift bar lift, and stop into water.
Yet people find after reality is used, 1), during low-water level still there is following some problem in this case:, outstanding son and the son that suspends remain the pulling force to the switch handle tail, make shift bar that non-response distortion or fracture very easily occur, thereby significantly reduced serviceable life and the reliability of equipment; 2) although, to be provided with weight be anti-tangle thing for outstanding son and the son below that suspends, outstanding son and suspension still can be along with current drift about, thereby cause switch to open by mistake, serious impact the reliability of equipment; 3), in this case, as long as water level is lower than peak level, suspension just can the Drawing switch handle, and starts water inlet; On the one hand, if water tank go out the water intake velocity that water speed is less than pump, very easily cause the water level superelevation; On the other hand, the continuous firing of pump, also brought great load to equipment, thereby significantly reduced the serviceable life of equipment.
