Automatic water feeding control device of solar water container

Abstract

The invention provides an automatic water inlet controlling device with simple structure, low cost, durable service and zero energy consumption for the water tank, which aims at solving the problems in the existing automatic water inlet controlling device of the water tank of the solar water heater, such as the complex structure, high cost, electricity consumption and poor safety. When the water tank is filled with water, the automatic water inlet controlling device can automatically close a water inlet valve; when the water level of the water tank is lowered, the automatic water inlet controlling device can open the water inlet valve automatically, thus saving the manual labor, power source and water resource. The automatic water inlet controlling device comprises an outer container with an air outlet, a floater on the water surface and in the outer container, and an admission pipe with a valve and communicated with the upper part of the outer container; the lower part of the outer container is communicated with the inlet of the water tank; and the valve comprises a valve base, a valve core and a switch; wherein, a water inlet channel in the valve base is communicated with a water inlet of the valve; driven by the rising floater, the switch renders the valve core to move and close the valve; and the air outlet is arranged higher than the water inlet of the valve.

Description

technical field [0001] The invention relates to a water tank automatic water inlet control device, in particular to a water tank automatic water inlet switch control device on a solar water heater. Background technique [0002] Solar water heaters are very practical energy-saving products. Generally, a gate valve is installed on the water inlet pipe of the water tank. When the water enters, the gate valve is opened; when the water tank is full, the gate valve is closed. Since the switch of the gate valve needs to be controlled manually, someone needs to wait to see if the water tank is full (see if there is return water in the return pipe of the solar water tank) when the water enters, which wastes valuable human resources. In addition, even if someone closes the valve, it will still waste of water. Also on some solar water heaters, an automatic water inlet control device has been used to automatically stop the water inlet after the water tank is full. Just because of abov...
