Water inlet valve device installed in water tank

Abstract

The invention discloses a water inlet valve device installed in a water tank, which comprises a valve body, a control valve, a control rod and a floating bucket. The valve body internally forms a water inlet channel, the control valve fits in the water inlet channel, the floating bucket is connected with the control valve through the control rod, a connecting block is installed on the control rod,the control rod is connected with the control valve through the connecting block, a first magnetic attraction piece is arranged at the lower end of the connecting block, and a second magnetic attraction piece matched with the first magnetic attraction piece is arranged at the position, near the connecting block, on the valve body. According to the water inlet valve device, the first magnetic attraction part and the second magnetic attraction part which are matched in a magnetic attraction mode are arranged, before the water tank is supplied fully with water, the water inlet channel supplies water to the water tank with the maximum water flow, so that the water inlet valve device has the advantage of being rapid in water supplying; and after magnetic attraction is lost between the connecting block and the valve body, water in the water tank can quickly lift the floating bucket, the floating bucket quickly closes the water inlet channel through the control rod linked with the control valve, and water supplying to the water tank is quickly stopped.

Description

technical field [0001] The invention relates to the technical field of water inlet valves, in particular to a water inlet valve device installed in a water tank. Background technique [0002] The water inlet valve device installed in the water tank in the prior art generally includes a valve body, a control valve, a control rod and a floating barrel; the valve body is installed in the water tank, and a water inlet channel is formed in the valve body; the control valve is installed on the valve body Cooperate in the water inlet channel to control the flow of water in the water inlet channel; the floating bucket is movably fitted on the valve body through the control rod, and connected to the control valve through the control rod to open or close the control valve. [0003] However, it is found through observation that when the floating bucket needs to close the control valve through the control rod, the floating bucket slowly raises the control rod as the water level in the w...

Problems solved by technology

[0003] However, it is found through observation that when the floating bucket needs to close the control valve through the control rod, the floating bucket slowly raises the control rod as the water level in the water tank rises slowly, and the control valve is slowly closed through the control rod. The water channel, and as the water inlet channel is slowly closed, the water supply is gradually reduced, the water level in the water tank rises more slowly, and the speed at which the floating bucket closes the control valve through the control rod also becomes slower, which is obvious Yes, the existing water inlet valve device cannot quickly fill up the water, nor can it stop the water quickly
