The valve core assembly is arranged above the water flow section 2 13, and the water stop plate 4 seals and opens the water flow hole 14.

[0024] The working principle of the utility model is as follows: Figure 1 As shown, when the water stop plate 4 seals the water hole 14, and water flows from the water section 13 to the water section 1 12, the water in the water section 13 flows to the cavity 6 through the water channel 7, and the pressure on the upper and lower sides of the water stop plate 4 is the same; when the water stop plate 4 seals the water hole 14, and water flows from the water section 1 12 to the water section 2 13, there is no water in the water section 2 13, that is, the pressure below the water stop plate 4 is zero, and due to the obstruction of the valve core body 2, the water in the water section 1 12 will not flow into the upper part of the water stop plate 4, that is, the pressure above the water stop plate 4 is zero, and the pressure on the upper and lower sides of the water stop plate 4 is the same;

[0025] like Figure 2 As shown, when the water stop plate 4 opens the water hole 14 and water flows from the water pass section 2 13 to the water pass section 1, the water pass section 2 13 flows to the cavity 6 through the water channel 7, and the pressure on the upper and lower sides of the water stop plate 4 is the same; when the water stop plate 4 opens the water hole 14 and water flows from the water pass section 1 12 to the water pass section 2 13, a part of the water flowing from the water pass section 1 12 into the water pass section 2 13 flows to the cavity 6 through the water channel 7, and the pressure on the upper and lower sides of the water stop plate 4 is the same.

[0026] The utility model connects the cavity 6 and the second water passing section 13 through the water passing channel 7, effectively balancing the pressure on the upper and lower sides of the water stop plate 4, and effectively preventing the water stop plate 4 from vibrating up and down, thereby reducing noise.

In this embodiment, the horizontal hole 7a is partially arranged in the groove 8.

[0030] In order to reduce the impact of the water flow in the water flow section 12 on the water stop plate 4, the lower end of the sealing seat 5 extends downward to form a fence portion 9 surrounding the outer periphery of the water stop plate 4.

[0031] In order to reduce the number of assembly steps and ensure the connection strength between the fence portion 9 and the sealing seat 5 , the fence portion 9 and the sealing seat 5 are an integrated structure.

[0032] In order to achieve a better sealing effect of the sealing seat 5 , a sealing ring 10 is sheathed outside the sealing seat 5 to seal the gap between the sealing seat 5 and the valve core body 2 .

[0033] The installation structure of the sealing seat 5 and the water stop plate 4, the valve core rod 3 includes a limiting section 3a, a mounting section 3b and a threaded section 3c arranged in sequence from top to bottom, the sealing seat 5 and the water stop plate 4 are sleeved on the mounting section 3b, a nut 11 is screwed on the threaded section 3c, and the sealing seat 5 and the water stop plate 4 are limited between the limiting section 3a and the nut 11.
