The working principle of the water-saving valve of the application is as follows: when water is needed, the valve cap 14 is pressed down, the valve cap 14 pushes the flow stopping mechanism 15, the flow stopping mechanism 15 is opened to drain water, and after a hand leaves the valve cap 14, the valve cap 14 is slowly reset under the cooperation of the reset spring 16 and the slow reset rubber ring 41 until the flow stopping mechanism 15 is closed;

when the single-time water discharging time is longer, the adjusting handle 72 is rotated to extend the adjusting rod 71 towards the valve body 11, so that the adhesion degree of the anti-skid rubber block 73 and the side wall of the valve body 11 is increased, the friction force is increased, and the resetting time of the valve cap 14 is prolonged;

when the valve cap 14 needs to be in a water discharging state for a long time, after the valve cap 14 is pressed down, the locking rod 81 extends towards the valve body 11 by rotating the locking handle 82, the locking rod is clamped into the clamping groove 83 to lock the valve cap 14, at the moment, the flow stopping mechanism 15 is in a normally open state, after water is used, the locking handle 82 is rotated reversely, the locking rod 81 is withdrawn from the clamping groove 83, and the valve cap 14 is automatically reset.

In a preferred embodiment, the flow stop mechanism 15 includes a valve stem 51 disposed in the middle of the bottom end of the bonnet 14 and extending into the valve body 11; the return spring 16 is sleeved on the valve rod 51, so that the return spring 16 extends and retracts along the axial direction of the valve rod 51, and the positioning effect on the return spring 16 is good; the valve rod 51 extends into the end part of the valve body 11 and is fixedly provided with a circular valve clack 52 positioned between the water inlet 12 and the water outlet pipe 13; a check ring 53 is arranged on the inner side wall of the valve body 11 and clings to the valve clack 52; the inner diameter of the flow stopping ring 53 is smaller than the outer diameter of the valve clack 52, and the valve clack 52 is matched with the flow stopping ring 53 to play a role in sealing and water breaking.

In a preferred embodiment, a sealing rubber strip 54 is fixedly arranged between the check ring 53 and the valve clack 52, so that the sealing effect of the check ring 53 and the valve clack 52 is increased; the through part of the valve rod 51 extending into the valve body 11 is provided with a sealing rubber ring, so that the waste caused by leakage from the joint when water is drained is prevented.

In a preferred embodiment, the end of the water outlet pipe 13 far away from the valve body 11 is bent to form a vertically downward water outlet 31, so that the water can be taken and used conveniently when water is discharged.
