Abstract

The utility model relates to an automatic miniature water supply device with stable pressure. A one-way check valve, a water pressure double control relay and a pressure control air chamber are orderly connected to a pipeline between a water pump and a water using device; the water pressure double control relay has the two-stage control of a normally closed contact and a normally open contact, a circuit of the water pressure double control relay is connected with a power supply and a motor of the water pump, and is provided with a main switch of a control circuit. The utility model obtains the purpose of the automatic and stable water supply of a self-provided water pump, and the self-provided water pump can also supply water for automatic washing machines and water heaters. The utility model has the advantages of high sensitivity and reliability, simple structure, small size, low cost, convenient installation and operation, etc.

Description

Small-sized automatic voltage regulation water feeder

The utility model relates to domestic water supply equipment, refers in particular to a kind of small-sized automatic voltage regulation water feeder.

Particularly the rural area is used and to be provided water pump for oneself in the many areas of China, and unshared housing's self-contained water source does not also have automatic water supply equipment now, generally need drive electric switch, goes the pump of cutting off the water after seeing the water vat full water, must be regularly, and trivial operations, trouble, very inconvenient.Some modernized household electrical appliances such as washing machine, geyser etc. can not use at all.

The purpose of this utility model provides a kind of small-sized automatic voltage regulation water feeder, can control automatic water-supply by hydraulic pressure, and is easy to use, and cheap.

The purpose of this utility model is achieved in that a kind of small-sized automatic voltage regulation water feeder, is made up of pump motor and related valve, electrical equipment:

Single-phase flap valve has been linked in sequence on the pipeline between water pump and the watering equipment, the two controlled relays of hydraulic pressure pressure, pressure control air chamber, the two controlled relays of described hydraulic pressure pressure have constant close contact and the control of constant open contact twin-stage, the circuit of this relay is connected with power supply and pump motor, and is provided with the control circuit master switch.

During enforcement, on the pipeline between described water pump and the watering equipment, between water pump and one way stop peturn valve, be connected with stop valve.

The utility model has following actively useful effect:

1. realize that automatic stabilisation supplies water, make and provide water pump for oneself and also can give automatic washing machine, water supply of water heater;

2. sensitive reliable: use the open and close of hydraulic signal by air chamber pressure switch control of pump motor, performance sensitive is reliable;

3. simple in structure, volume is little, and weight is less than one kilogram, and is cheap, is fit to the vast rural area level of consumption;

4. the rural area of becoming better-off now presses for tap water, adds a small-sized water supplying apparatus in the middle of the water pump supply channel, just can deal with problems fully, and is easy for installation.

Now in conjunction with the accompanying drawings with preferred embodiment:

Fig. 1 is pipeline and the circuit diagram of the utility model embodiment.

Small-sized automatic voltage regulation water feeder of the present utility model, form by pump motor and related valve, electrical equipment:

At water pump 1 and watering equipment (for example running water pipe A, B, automatic washing machine C, geyser D, shower E) between pipeline on the single-phase flap valve 2 that has been linked in sequence, the two controlled relays 3 of hydraulic pressure pressure, pressure control air chamber 4, the two controlled relays 3 of described hydraulic pressure pressure have constant close contact 5 and the control of constant open contact 6 twin-stages, the circuit of this relay is connected with power supply and water pump 1 motor, and is provided with control circuit master switch K.

During enforcement, on the pipeline between described water pump 1 and the watering equipment, between water pump 1 and one way stop peturn valve 2, be connected with stop valve 7.

Operating principle of the present utility model:

Open leading A, pipe network water pressure reduces, and water pump is opened and supplied water under the pressure switch effect, when leading A closes, pipe network water pressure raises, and is high to a certain degree (levelling is pressed generally at 0.3Mpa pressure), and pump motor is under the pressure switch effect and close, flap valve in the water pipe works simultaneously, the water of water pipe is not flow backwards, make ductwork pressure keep the long period (if not water, experimental results show that hydraulic pressure can keep more than one month) by the small air chamber again.If water, pipe network water pressure is reduced again, drop to a certain degree (levelling is pressed and is 0.05Mpa), motor and water pump is opened by pressure switch, make ductwork pressure keep within the specific limits (general levelling is pressed in 0.3-0.05Mpa) like this, thereby reach the purpose of full automatic water supply.If used water pump is bigger; hydraulic pressure can occur raises rapidly; before pressure switch and air chamber, add an adjustment valve; control inflow; (general small-sized submersible pump can not occur or not startup frequently and shutdown phenomenon when making it to hold tap; few water pump, the water yield occur when big, just can remove fully as long as adjust the water transfer valve.)。

Vast rural area has a lot of water pumps that oneself opens to supply water, trivial operations, modern household electrical appliances, automatic washing machine, Water-heating shower can't use at all, and (volume does not also have the medium-sized of geyser to add a very cheap of the present utility model small-sized water supplying apparatus on pipe network, weight is less than one kilogram), cost is also very low, just can reach the purpose of automatic water-supply fully, uses very convenient.

Claims

1. small-sized automatic voltage regulation water feeder is made up of pump motor and related valve, electrical equipment, it is characterized in that:

2. small-sized automatic voltage regulation water feeder as claimed in claim 1 is characterized in that: on the pipeline between described water pump and the watering equipment, be connected with stop valve between water pump and one way stop peturn valve.
