Abstract

The utility model provides an automatic liquid level controller. The upper limit liquid level makes a liquid pump stop, and the lower limit liquid level makes the liquid pump start. The automatic liquid level controller comprises a float and a mercury switch used to control the liquid pump, and the mercury switch is fixed on a rising wane. The rising wane uses a float driving lever, a top plate (block) and a press plate (block) to drive the mercury switch to switch on and switch off following the limit liquid level, and the mercury switch has two stable states: the switch on and the switch off which are inter-switched. The mercury switch can control if the liquid pump is operating. The utility model has the advantages of simple structure, stable and reliable operation and no environmental influence.

Description

Automatic liquid level controller

The utility model relates to a kind of upper limit liquid level quits work liquid pump, the leve automatic controller that bottom limit level starts liquid pump, and it includes float and liquid pump switch.

The patent No. is that 90218643.4 " Full Automatic Liquid level controller " discloses a kind of leve automatic controller, it is provided with high, medium and low three liquid level rapiers, these three rapiers are in cistern, by the lifting of liquid level, make rapier connect conducting or disconnection, the actuating of relay, whether control liquid pump work, the assurance liquid level is controlled within the specific limits all the time, and this fluid level controller is because the corrosion of rapier easily causes control malfunctioning.

Task of the present utility model provides a kind of simple in structure, the stable and reliable operation leve automatic controller.

Task of the present utility model is finished as follows, it is a kind of switch that includes float and control liquid pump, switch is a disconnection that has that has been fixed on the seesaw, the mercury cut-off of closed two steady state (SS)s, it has a seesaw that can press down when the bottom limit level that is driven by float and drive link thereof, and to make mercury cut-off be the pressing plate (piece) of the bottom limit level startup liquid pump of closure state by the off-state upset, also has one by floating and drive link drives when the upper limit liquid level, the jack-up that can make progress is played seesaw, and the upper limit liquid level that makes mercury cut-off switch to off-state by closure state is stopped the top (piece) of liquid pump.It adopts mechanical drive principle, drives mercury cut-off, makes mercury cut-off come closed or disconnection with limit liquid level, and whether it directly controls liquid pump work with mercury cut-off, and it is simple in structure, and cost is low, is not subjected to environment, water quality, temperature limitation, and working stability is reliable.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Fig. 1 is a mechanical schematic diagram of the present utility model.

The structural representation of the horizontal leve automatic controller that Fig. 2 provides for the utility model.

The structural representation of the vertical leve automatic controller that Fig. 3 provides for the utility model.

1-pressing plate (piece) 2-plays seesaw 3-mercury cut-off 4-top board 5-drive link 6-float in Fig. 1, Fig. 2, Fig. 3

Below further specify structure of the present utility model and working condition by accompanying drawing.

The float of this leve automatic controller (6) is with the liquid level lifting, when liquid level drops to bottom limit level, float (6) descends, drive pressing plate (piece) (1) by drive link (5) and pressed down seesaw (2), make the mercury cut-off (3) that has been fixed on the seesaw (2) switch to group and close state, liquid pump work by off-state.With liquid pump work, liquid level constantly rises, when liquid level reaches upper limit liquid level, float (6) rises, drive top board (piece) (4) jack-up seesaw (2) by drive link (5), make the mercury cut-off (3) that has been fixed on the seesaw (2) switch to off-state by closure state, liquid pump quits work.

Claims

1, a kind of leve automatic controller, it includes the switch of float and control liquid pump, it is characterized by: switch is a disconnection that has that has been fixed on the seesaw, the mercury cut-off of closed two steady state (SS)s, it have one by float and drive link thereof drive when the bottom limit level, can having pressed down seesaw, to make mercury cut-off be the pressing plate (piece) that the bottom limit level of closure state starts liquid pump by off-state upset, also have one by float and drive link thereof drive when the upper limit liquid level, the jack-up that can make progress is played seesaw, and the upper limit liquid level that makes mercury cut-off switch to off-state by closure state is stopped the top board (piece) of liquid pump.
