Abstract

The invention provides a delay shutoff valve which comprises a valve body of which two ends are opened, wherein a hollow driving seat can be rotationally arranged in an upper end port of the valve body; a moving plate is arranged below the driving seat; an accommodation cavity for allowing water current to flow into is formed between the moving plate and the driving seat; a central water outlet is formed in the moving plate; a fixed plate with a central water outlet is arranged below the moving plate; a valve cap is arranged below the fixed plate; a hollow connecting piece is fixedly arranged in the driving seat; the upper part of the connecting piece extends out of the driving seat and is fixedly inserted into a lower cover; a driving shaft unit can be arranged in the connecting piece in a sliding way and at an interval from a V-shaped sealing ring; an upper cover is fixedly connected to the upper part of the driving shaft unit; a spring is clamped between the upper cover and the lower cover; and the lower part of the driving shaft unit downwards extends out of a water outlet of the moving plate. The delay shutoff valve provided by the invention not only has a delay closing function, but also can be used for adjusting the temperature and the flow of water current.

Description

technical field [0001] The invention relates to a valve, in particular to a time delay closing valve. Background technique [0002] Now, time-delay shut-off valves are widely used in public places such as public toilets, stations, hotels, etc. On the one hand, they can effectively save water. It is very convenient to operate without having to touch the faucet with your hands. Just disclose a kind of time-delay valve as CN2733129Y, it comprises the valve body of belt inlet, outlet, and the baffle plate of separating water inlet and outlet and the time-delay cavity of controlling water discharge time are arranged in the valve body, and the middle of baffle plate is provided with through hole A floating body is installed in the delay chamber through the through hole, a valve core is installed above the floating body, and a water diversion groove is opened on the inner side wall of the delay chamber and at the matching place with the floating body. However, the existing time-d...
