[0029] like Figure 1 - Figure 4 As shown, a water-saving valve of the utility model comprises a valve body 1, a valve core 3 and a blocking portion 32;

[0030] One end of the valve body 1 is closed, and the other end is provided with a sealing valve cover 2. A low-position water inlet 10 and a high-position water outlet 11 are respectively provided on both sides of the valve body 1.

[0031] The valve core 3 is sleeved in the valve body 1, and a spring 4 is arranged between the valve core 3 and the inner top surface of the valve body 1;

[0032] A through hole 30 is formed through the bottom and side of the valve core 3;

[0033] A spring 4 is set in the water-saving valve. When the water is cut off, the valve core 3 is pushed downward during the recovery process of the spring 4 from compression, so that the through hole 30 on the side of the valve core 3 cannot be connected with the high-position water outlet 11, and the water flow is blocked. The valve core 3 can actively stop the flow, avoiding the waste of water when the water valve is not closed in time or forgotten to be closed.

[0034] A sliding plate 31 is provided at the edge of the valve core 3, and the sliding plate 31 extends from the bottom of the valve core 3 to the upper edge of the low-position water inlet 10;

[0035] The blocking portion 32 is disposed at one end of the sliding plate 31 close to the low-position water inlet 10;

[0036] After the valve core 3 is acted upon by the spring 4 , it moves along the setting direction of the valve body 1 , the through hole 30 is disconnected from the high-position water outlet 11 , and the blocking portion 32 cooperates with the low-position water inlet 10 .

[0037] A sliding plate 31 is provided at the bottom of the valve core 3. When the valve core 3 moves, the blocking portion 32 can be driven to move downward together, thereby blocking the flow of the low-position water inlet 10 at the same time, and the blocking effect is further enhanced.

[0038] Specifically, the sliding plate 31 and the blocking portion 32 are combined to form an L-shape.

[0039] A groove 320 may be formed in the blocking portion 32 , and a ball 321 may be placed in the groove 320 .

[0040] In addition, ridges 33 are provided on both sides of the valve core 3, and the ridges 33 extend along the moving direction of the valve core 3. A slide groove (not shown in the figure) matching the ridges 33 is provided on the inner wall of the valve body 1. The ridges 33 and the slide groove can guide the movement of the valve core 3 to avoid the valve core 3 shaking and causing a gap between the through hole 30 and the high-position water outlet 11, thereby preventing water leakage.

[0041] A guide rod 5 is connected to the top of the valve core 3 , one end of the guide rod 5 passes through the sealing valve cover 2 , and the spring 4 is sleeved on the outer periphery of the guide rod 5 .

[0042] In addition, a retaining ring 13 can be provided on the inner wall of the valve body 1. The retaining ring 13 is located above the valve core 3. After the water supply is restored to normal, the valve core 3 is pushed downward under the action of water pressure and the spring 4 is compressed. The retaining ring 13 is provided so that when the valve core 3 contacts the retaining ring 13, the valve core 3 is at the highest point in the valve body 1.
