Abstract

The utility model discloses a water level controller for a water tank of a solar water heater, which is composed of a self-control electromagnetic valve and a detecting float. The middle part of a valve body is provided with a valve disc and a seal ring which is provided with two holes A and B, and a pressure spring is arranged between a valve core and a valve body which are arranged at the upper part of the valve disc. A permanent magnet is fixedly connected with a button, and a spring is arranged between the button and the valve body. The valve body arranged at the lower part of the permanent magnet is provided with an electric magnet, an electromagnetic coil and a spring piece. An inner switch is composed of the permanent magnet and the spring piece, and the inner of a valve cover is provided with a battery warehouse. The detecting float is composed of a float, a conducting wire and a mercury switch which is arranged on the float. The utility model effectively solves the problem of automatic water level control of the solar water heater.

Description

The solar water heater water tank water-level control apparatus

The utility model relates to the cistern water level control device, refers in particular to use water level automatic control device in the solar water heater water tank water filling.

Modes such as water spill-over stream, electric bell warning, water level demonstration, water meter indication are adopted in the present full prompting of solar water heater water tank water filling more.These modes must be carried out under people's supervision and operation, carelessly slightly just the phenomenon of metalling run out can occur, and waste people's time and efforts.

Use existing magnetic valve on tap water pipe line, an external controller and condensate tank of dehumidifier can solve the last water level of water tank and control automatically.But the opening of existing magnetic valve needs keeping of electricity, uses civil power not susceptible to user acceptance, and then battery life is too short to use battery.

The purpose of this utility model is to provide a kind of solar water heater water tank water-level control apparatus, and it is unattended that it can make the water process accomplish, and only depends on dry cell just can normally use.

The purpose of this utility model is achieved in that

The solar water heater water tank water-level control apparatus, form by the detection float two parts that can be loaded on the automatic control solenoid valve on the tap water pipe line and can be contained on the water tank, it is characterized in that: sealing ring and the valve disc of establishing A, B two holes are housed at the middle part of valve body, are contained between the spool on valve disc top in the valve body and the valve body compression spring is housed; Permanent magnet is fixedlyed connected with button, and a compression spring also is housed between button and the valve body, and electromagnet, solenoid and spring leaf are housed on valve body below the permanent magnet, switch in permanent magnet and spring leaf constitute; In valve gap, be provided with battery compartment; Detect float by float and the mercoid switch on being contained in float reach the lead that links to each other with magnetic valve and constitute.

When float was sagging naturally, mercoid switch disconnected, and pressed the button of automatic control solenoid valve, switch is logical in the valve, valve open, the water tank water filling, cistern water level rises and makes the float levitating, mercoid switch is connected, button automatically springs open, and buzzer is sent out a minor, and switch disconnects in the valve, water filling stops, and controls automatically thereby realize going up water level.

The utility model has the advantages that:

Automatic control solenoid valve is without external power supply, and that self realizes the water route manually opens automatic pass with external condition, and it is simple to detect Floater Structure, uses reliable.

Further specify in conjunction with the accompanying drawings with regard to concrete structure of the present utility model and circuit theory below.

Fig. 1 is the utility model automatic control solenoid valve water route closed condition cutaway view;

Fig. 2 is the utility model automatic control solenoid valve water route opening cutaway view;

Fig. 3 detects Floater Structure figure for the utility model;

Fig. 4 is the utility model circuit theory diagrams.

Automatic control solenoid valve is by carrying out and controlling two unit and form.Performance element mainly comprises valve body 11, valve disc 12, sealing ring 13, spool 14, spring 15 and gland 16, two aperture A and B are arranged on sealing ring 13 and valve disc 12, spool 14 can be realized displacement under the effect of magnetic force and spring force, open or blind hole B, when hole B is closed, as Fig. 1, sealing ring 13 and valve disc 12 cut off water inlet and delivery port under the effect of hydraulic pressure.When hole B is opened, under the effect of hydraulic pressure, lift water inlet and delivery port UNICOM as Fig. 2 sealing ring 13 and valve disc.

The control power supply mainly comprises permanent magnet 22, spring 24, solenoid C, electromagnet 23, button 25, buzzer D binding post X and housing 26.

Spring leaf

28,29 and permanent magnet 22 are formed switch (see figure 4) in the valve.Establish battery compartment on the housing 26, electromagnet 23 is fixedly connected with valve body 11, and permanent magnet 22 is fixedly connected with button 25.When permanent magnet 22 was pressed and contacts with electromagnet 23, K switch A was switched in the valve, referring to Fig. 4.If the outer mercoid switch KW of valve is in off-state, then solenoid C does not power up, and electromagnet 23 is subjected to the attraction of permanent magnet 22, and this moment, spool 14 was picked up valve open.When mercoid switch was in conducting state, solenoid C powered up, and permanent magnet 22 is by pop into position, and K switch A disconnects in the valve closing, valve.

Referring to Fig. 3, detect float and mainly comprise float 30, mercoid switch KW, lead 31, steel wire 32, sleeve pipe 33 and Si Sai 34, when float was sagging, mercoid switch KW disconnected, when float is floated by water, mercoid switch KW conducting.
