Description

The liquid level timer

Technical field

The utility model relates to a kind of liquid level timer, relates in particular to a kind of liquid level timer that is used on the water pump.

Background technology

Water supply pump in the residential block can send very big noise when the bottom of the building layer is worked at present, because water pump is to work according to the liquid level height of water tank, if the liquid level of water tank descends, then water pump will start at any time and carry out work, if water pump started at night, the noise that then sends can have a strong impact on resident's normal rest and life, owing to causing that the reason that water pump sends noise is diversified, for example, pipe vibration, base and bolt are gapped, current and impeller friction, pump body vibrations etc., so produce little effect, brought very big puzzlement for resident's life at the improvement that reduces the water pump noise.

The utility model content

A kind of liquid level timer that the utility model provides can be controlled the startup and the shut-in time of water pump, has avoided water pump to start at night, has guaranteed resident's rest.

In order to achieve the above object, the utility model provides a kind of liquid level timer, comprises time program controller and chronotron that circuit connects;

Described time program controller comprises first relay, timer and first triode, also comprises auxiliary reclay;

The connect base stage of described first triode of the connect collector of described first triode of described first relay, the output terminal of described timer;

Described first relay comprises a normally opened contact, when first relay is worked, and this normally opened contact adhesive;

First stabilivolt also in parallel on described first relay;

Described auxiliary reclay is connected with described normally opened contact; When this auxiliary reclay gets when electric, water pump is started working;

Described time program controller also comprises resistance and the electric capacity that some circuit connect;

Described chronotron comprises second relay, second triode, delay circuit and magnetic sensible switch;

The connect collector of described second triode of described second relay, described delay circuit is connected in parallel between the base stage and emitter of described second triode, and described magnetic sensible switch is connected in parallel between the base stage and collector of described second triode;

Described second relay comprises a normally closed contact, and when first relay was worked, this normally closed contact disconnected;

Second stabilivolt also in parallel on described second relay;

Described delay circuit comprises time delay resistance, variable resistor and the delay capacitor of series connection successively;

Further, described liquid level timer also comprises fuse, rectifier power source, the voltage stabilizer that circuit connects, and some resistance and some electric capacity;

The liquid level timer that the utility model provides is when work, timer is set, set the startup and the shut-in time of timer, when having arrived the start-up time of setting, timer is triggered, the first triode conducting, first relay is got, normally opened contact is closed to be connected, and gets electricly by auxiliary reclay, and water pump is started working and inject water in water tank;

When water is filled with the waterline that reaches setting, magnetic sensible switch is by instantaneous triggering and conducting, thereby make the second triode conducting, second relay gets, normally closed contact disconnects, the auxiliary reclay dead electricity, water pump stops to inject water to water tank, owing to also be in the start-up time of timer this moment, so the normally opened contact of first relay also is in closed on-state, if this section in start-up time the water level in the water tank decline is arranged, then magnetic sensible switch disconnects, second relay electric-loss, the normally closed contact closure, water pump continues water filling in water tank, thus, between the starting period of timer, the cistern water level fluctuation can cause the frequent start-stop of water pump, be unfavorable for normal operation, so value over head time of utilizing chronotron that timer is set is discharged: when water was filled with the waterline that reaches setting, magnetic sensible switch was by instantaneous triggering and conducting, thereby make the second triode conducting, second relay gets electric, and normally closed contact disconnects, the auxiliary reclay dead electricity, water pump stops to inject water to water tank, this moment under the delay circuit effect, second relay always electric, make normally closed contact be in off-state always, after the delay capacitor discharge surpasses the shut-in time of timer, just recover original state, the variable resistor in delay circuit, scalable discharge delay time.

A kind of liquid level timer that the utility model provides, can control the startup and the shut-in time of water pump, can avoid after water pump temporarily quits work simultaneously, because the frequent start-stop of water pump that cistern water level fluctuates and causes, thereby avoided water pump working at night, guaranteed resident's rest.
