Water flow monitoring control reversing valve for solar water heater and control method thereof

Abstract

The invention relates to a water flow monitoring control reversing valve for a solar water heater and a control method thereof. The water flow monitoring control reversing valve comprises a reversing valve, a water flow monitor, a motor and a control driver. The water flow monitoring control reversing valve is characterized in that: the reversing valve comprises a fixed valve core with four runners and a dynamic valve core with a single runner, the shapes of the dynamic valve core and the fixed valve core are matched, the dynamic valve core is coaxially and rotationally arranged on the fixed valve core, the runner on the dynamic valve core simultaneously covers two or three runners on the fixed valve core, the dynamic valve core is electrically connected with a motor, the motor is electrically connected with a control driver, the water flow monitor is connected in series between a user head water resource and a water tap, and the water flow monitor is electrically connected with the control driver. By coordination of the water flow monitor, the control driver and the motor, the position of the dynamic valve core in the reversing valve can be automatically sensed and adjusted, and water injection, water utilization and emptying of the solar water heater can be automatically controlled; and the reversing valve is convenient, fast and safe to use.

Description

technical field [0001] The invention relates to a water flow monitoring control reversing valve used for a solar water heater and a control method thereof. Background technique [0002] At present, the hot water in ordinary non-pressurized solar water heaters flows out by natural drop, so the hot water outlets are all set at the bottom of the water tank, and the solar hot water pipeline emptying solenoid valve and the mountain water solenoid valve are installed at the bottom of the solar water heater. Shuikou. Since scale is mainly composed of minerals with high density, the failure of solenoid valves and sensor probes due to the precipitation of a large amount of scale has been a difficult problem that has not been completely solved in the industry in the past 20 years. In addition, a large amount of water level and water temperature monitoring systems need to be configured additionally, which also increases the cost of use. In particular, it violates the principle of flu...

Problems solved by technology

The regulating spool includes a fixed spool and a movable spool that can rotate or move on the fixed spool, four through holes are opened on the fixed spool, two grooves are opened on the movable spool, and The two grooves match the four through holes on the fixed valve core. Although this patent is different from the principle of conventional solar water heaters relying on natural drop water, the structure of the control valve disclosed in this patent is relatively complicated and needs to be installed at each water point. The above-mentioned control valve uses a special matching faucet, so the cost of popularizing and using the equipment is relatively high

In addition, the entire water control process needs to be completed manually, which is inconvenient to use
