The invention discloses a pressure automatic water closing water feeding valve for a solar water heater. The pressure automatic water closing water feeding valve comprises a valve body, a water feeding channel is formed in the valve body, a ball valve element is mounted in the water feeding channel in a sealed manner, a water feeding rod and a control rod are symmetrically mounted at two ends of the ball valve element, and a control cavity and a hydraulic cavity are formed in the valve body. Two sliding sleeves are symmetrically mounted on the inner wall of the control cavity, a toothed bar iscommonly inserted into the two sliding sleeves in a sliding manner, the end, away from the water feeding rod, of the control rod extends into the control cavity and is provided with a control gear, and one end of the toothed bar extends into the hydraulic cavity and is provided with a piston plate. According to the pressure automatic water closing water feeding valve for the solar water heater, the ball valve element and the piston plate are linked through the control gear and the toothed bar, the piston plate and a piston column are linked through the hydraulic cavity and a pressure guide pipe, the ball valve element can be reversely controlled to be closed through the piston column by means of water full overflow water pressure, the function of automatically closing water when water isfull is achieved, electric control is not needed, and the valve is wider in applicability and more reliable.
Description
technical field [0001] The invention relates to the field of control valves, in particular to a pressure-automatic water supply valve for a solar water heater. Background technique [0002] Solar water heaters are the must-have environmentally friendly household water heaters for most residential users. Solar water heaters heat the hot water in the water storage tank through light energy conversion for residents to use. Put the tap water into the water storage tank by using the water supply valve, and then judge whether it is full through the overflow pipe, and then close the valve. It is necessary to pay attention to the overflow pipe at all times to avoid a large amount of water overflowing if the valve is not closed in time. [0003] The existing electric control water shut-off valve solves the problem of needing to pay attention to the overflow at all times, so that the water supply valve is automatically closed when the overflow water is sensed, which can not only avoid...
