Title:
LEAK-PROOF DEVICE FOR WATER INLET VALVE
Document Type and Number:
WIPO Patent Application WO/2018/137053
Kind Code:
A1
Abstract:
Disclosed is a leak-proof device for a water inlet valve. A water inlet channel (11) and a water outlet channel (12) are formed in a valve body (1), a control valve (9) is installed in the valve body (1), and the control valve (9) controls the opening and closing of the water inlet channel (11) and the water outlet channel (12). An outer water tank (2) is installed on the valve body (1), and a water inlet hole (21) is disposed at the bottom of the outer water tank (2); an inner water tank (3) is disposed in the outer water tank (2), with the height of the inner water tank (3) being lower than that of the outer water tank (2); and water overflows into the inner water tank (3) from the outer water tank (2). A lever (8) is pivotally connected to the valve body (1); an outer floating bucket (5) is installed at one end of the lever (8), the outer floating bucket (5) being placed in the outer water tank (2), and an inner floating bucket (6) is installed at the other end of the lever (8), the inner floating bucket (6) being placed in the inner water tank (3); and a plug (61) is installed on a lower end of the inner floating bucket (6). A leak-proof water tank (4) is installed on the valve body (1); the leak-proof water tank (4) is in communication with the inner water tank (3) via a water-passing channel (41); and the lever (8) swings to make the plug (61) close the water-passing channel (41) or open the water-passing channel (41). A leak-proof floating bucket (7) is placed in the leak-proof water tank (4); the leak-proof floating bucket (7) is connected to the control valve (9); and the leak-proof floating bucket (7) rises and then drives the control valve (9) to close the water inlet channel (11) of the valve body (1), so as to stop the feeding in of the water of the water inlet valve in a timely manner when the water tank leaks, thus saving on water resources.
