Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

as shown in fig. 1-2, a water control valve for a water tank of a solar water heater comprises a valve body 1 and a float chamber 2, wherein the valve body 1 is provided with a water inlet pipe 3 and a water outlet pipe 4, the valve body 1 and the float chamber 2 are both arranged in a protective shell 5, the bottom of one side surface of the protective shell 5 is provided with a communication interface 6 connected with the inner container of the water tank of the solar water heater, the top of the protective shell 5 is provided with a through hole 7, and the water inlet pipe 3 penetrates out of the through hole 7 and is fixed with the protective shell 5; the water outlet pipe 4 is connected with a water guide pipe 8, the lower end of the water guide pipe 8 is positioned in the communicating interface 6, an annular channel 9 is arranged between the water guide pipe 8 and the communicating interface 6, and when the communicating interface 6 is communicated with the inner container, the water guide pipe 8 is also communicated with the inner container. By adopting the technical scheme, when the water inlet pipe 3 is communicated with an external water source, water enters the water tank inner container of the solar water heater through the water inlet pipe 3, the valve body 1, the water outlet pipe 4 and the water guide pipe 8, when the water level in the water tank inner container of the solar water heater reaches a certain height, the water in the water tank inner container of the solar water heater enters the protective shell 5 from the annular channel 9 and enters the float chamber 2 from the hole at the lower end of the float chamber 2, and the float automatically closes the valve clack under the action of buoyancy to stop water inflow.
