Description

[Detailed Description of the Invention] The present invention relates to a water supply device such as a heater, and its purpose is to appropriately store water.

In a general water supply system, water is stored in a so-called distillation tank, and this water is supplied to a heating system or the like by an appropriate means.

The distern tank has a ball tap that opens and closes a valve according to the water level in the distern tank to keep the water level in the tank constant.

However, since the water supply control using the ball tap is performed by throttling the valve according to the water level in the tank, when the water level approaches the set water level, water spouts at the valve part, causing noise.

Furthermore, the above-mentioned system has a problem in that the water flow meter does not operate when a minute flow rate is consumed.

The present invention has been devised in view of the above-mentioned points, and the present invention will be described below based on examples.

1 is a box-shaped gas tank with an open top, and a water outlet pipe 3 connected to a water heater or other appliance is attached to the side wall 2 near the bottom.
Further, an overflow pipe 4 is connected above the set water level, and a water supply pipe 5 connected to a water source such as a water supply is connected further above this.

6 has screws 7, 7 on the inner surface of the side wall 2 of the distern tank 1.
・・・・・・A main body 11 formed by appropriately bending sheet metal to form at least a pair of vertical walls 8, 9 and a mounting wall 10 with a fixed pivot bracket, and a horizontal support to the vertical walls 9, 9 of this main body. It consists of a pivot pin 13 which is detachably attached in the direction and is prevented from being removed by an E ring 12.

Reference numeral 14 denotes a ball shaft whose one end is connected at a substantially right angle to a prismatic horizontal rotating shaft 15 rotatably supported by the pivot pin 13, and a floating ball 16 is fixed to the other end. The ball 16 rotates up and down about the rotating shaft 15.

Reference numeral 17 denotes a switch body mounted slightly above the pivot pin 13, which is a hollow cylindrical guide screwed onto the side wall 2 perpendicular to the pivot pin 13 and housing the reed switch 18 in a proper position inside. It consists of a cylinder 19 and an annular actuating body 21 which is slidably fitted loosely around the outer periphery of the guide cylinder and has a magnet 20 for actuating the reed switch 18 fixed to its inner surface.

Reference numeral 22 denotes a U-shaped frame-shaped drive body that slides the actuating body 21 in conjunction with the rotating shaft 15, and a pair of opposing pieces 23 and 23' are connected to the guide cylinder 19 so as to sandwich the actuating body 21 with a play gap. They are provided at intervals in the longitudinal direction and are fixed to the upper surface of the rotating shaft 15 with screws 25.

26 is a solenoid valve installed in the middle of the water supply pipe 5;
As shown in the figure, it is connected in series to a commercial power source 27 via the reed switch 18.

When the water level in the stern tank 1 drops below the set amount, the ball 16 lowers in accordance with the water level, and the rotating shaft 1
5 rotates and the pair of meat pieces 23 of the driving body 22 engages the actuating body 21.
slide it closer to the reed switch 18.

When the operating body 21 approaches the reed switch 18 to the set position, the magnet 20 causes the reed switch 18 to
is closed, the solenoid valve 26 is opened, and water is supplied into the gas turbine tank 1 through the water supply pipe 5.

Further, when the water level in the gas turbine tank 1 rises due to this water supply, the ball 16 rises and rotates the rotating shaft 15.

Then, the driving body 22 is moved by the rotating shaft 15,
First, it moves by the distance of the gap 24, and then moves while sliding the actuating body 21 with the opposing piece 23'.

When the operating body 21 moves away from the reed switch 18 by a set distance, the reed switch 18 is opened and the solenoid valve 26 is closed, stopping the water supply.

As mentioned above, the present invention consists of a gas turbine tank in which a water supply pipe communicating with a water source and having a solenoid valve interposed therein and a water outlet pipe communicating with appliances, etc. are connected at appropriate locations, and a tank that is rotatable above the tank. It is fixed to the end of a pivoted horizontal axis of rotation and a ball shaft connected approximately at right angles to this axis of rotation, and rotates up and down around the axis of rotation depending on the water level in the gas tank. a ball, a horizontal guide tube which is spaced from the rotating shaft in the vertical direction and fixed to the gas turbine tank with its longitudinal direction perpendicular to the rotating shaft, and the solenoid valve housed within the guide tube. A reed switch that controls opening and closing, an annular actuating body that has a magnet for activating the reed switch and is slidably fitted loosely around the outer periphery of a guide tube, and a guide tube that sandwiches the actuating body with a play gap. It consists of a pair of opposing pieces spaced apart in the longitudinal direction and a driving body fixed to the rotating shaft, and by controlling the water supply with a solenoid valve, it is similar to a conventional valve. What?
It is possible to prevent noise from being generated due to valve throttling.

Further, by interlocking the actuating body and the driving body with play, the ON/OFF time of the reed switch can be extended, and the durability of the solenoid valve etc. can be improved.
