Detailed Description

Referring to fig. 2, the upper valve body 2 is provided with an inner cavity 3;

referring to fig. 3 and 4, the lower valve body 4 is provided with a water inlet groove 5, a water outlet hole 6 and a water sealing part 7;

referring to fig. 5, a leather bowl seat 8 is provided with a delay hole 9;

referring to fig. 6, the control shaft 10 has a convex portion 11, a thick portion 12, and a thin portion 13;

referring to fig. 7, the pressing plate 14 has a shaft hole 15;

referring to fig. 8, the water sealing plate 16 is provided with a shaft hole 15;

referring to fig. 9, the leather cup 17 is provided with a communicating hole 18;

referring to fig. 10, the pressure relief piece 19 has a pressure relief hole 20;

wherein, the water sealing plate 16, the leather cup 17, the pressure relief piece 19 and the water sealing piece 21 are made of elastic colloid;

referring to fig. 1 to 16, a leather cup 17 is sleeved on a leather cup seat 8, a pressure relief piece 19 is fixed inside the leather cup seat 8 by a fixing piece 22, a water sealing piece 21 is fixed on the lower part of the leather cup seat 8 by the fixing piece 22, the leather cup seat 8 and a lower spring 24 are sequentially installed in a lower valve body 4, the water sealing plate 16 is arranged in a water sealing part 7, a pressing plate 14 is arranged on the water sealing plate 16, a control shaft 10 is arranged in a shaft hole 15, an upper spring 23 is sleeved on the control shaft 10 and is arranged between a convex part 11 and the pressing plate 14, an upper valve body 2 is arranged on the pressing plate 14 and is fixed with the lower valve body 4, a pressing piece 1 is arranged in an inner cavity 3, the upper end of the pressing piece 1 extends out of; wherein the delay hole 9 is opposite to the communication hole 18;

in the state shown in fig. 13, the control shaft 10 moves downwards by pressing the pressing piece 1 downwards, the upper spring 23 compresses and moves downwards to a certain position, the thin part 13 is arranged in the pressure relief hole 20, as shown in fig. 14, the pressure relief hole 20 is opened, the leather cup 17 and the leather cup seat 8 are flushed away from the water drainage hole 6 by water pressure, the water sealing piece 21 moves upwards to leave the water drainage hole 6, and the water drainage hole 6 is opened, as shown in fig. 15;
