A device for controlling water inlet of a pressure water valve with a rheostat box

Abstract

The invention discloses a method for controlling water feeding of a pressure water valve by using a water current resistance change box. The method comprises a solar water tank; the water current resistance change box is mounted on the solar water tank; the upper part of the water current resistance change box is an overflow storage cavity; a valve hole is formed in a valve hole plate at the lower part of the overflow storage cavity; a floating valve cavity is below the valve hole plate; a valve cover is on a floating object in the floating valve cavity; a floating pipe is inserted in a hole between the floating object and the valve cover; a thin through hole is in the floating pipe; when no water is in an impedance box, the floating object falls down to enable the valve cover to leave from the valve hole; the thin through hole can enable an air clearance to become smooth in middle of the valve hole; at this time, the pressure in the water tank is lower; when water fed in the solar water tank is ascended into the water current resistance change box, the floating object upwards floats to close the valve hole; only the thin through hole is remained for passing through water; at this time, the pressure in the water tank is suddenly increased; and the suddenly increased pressure closes a self-locking pressure water valve. The method for controlling water feeding of the pressure water valve by using the water current resistance change box has no need to pull conduction wires into user homes, is liable to adjust and excellent in reliability, and is a good helper for water conversion of the solar water tank.

Description

technical field [0001] The invention belongs to the field of automatic control of the liquid level of a solar water tank, in particular to a device for controlling the water inlet of a pressure water valve with a rheostat box. Background technique [0002] Many of the existing solar water tank liquid level controllers are combined with electric heaters, but the electric heating of the water tank has poor safety and high maintenance costs; another kind is to install a float valve in the water tank to control the water level, but this kind of valve Because the tap water is directly controlled, the float valve must be closed tightly, and it is often repaired due to water seepage. There is also a pressure valve that uses the water pressure difference between the water level in the water tank to automatically close the water inlet valve. The biggest advantage of this valve is that it does not need to pull the signal transmission line from the roof to the user's home, but directly...
