Through the cooperation between the water inlet valve body 1 and the protection mechanism 2, the liquid is repeatedly decompressed through the drain grooves 202 by the cooperation between the labyrinth ring 201 and the drain groove 202, thereby slowing down the impact on parts such as the valve ball 205. At the same time, due to the performance of the elastic ball 204, the inner sealing sleeve 203 drives the sealing block 207 to fully contact the sealing groove 206 to realize the sealing of the valve ball 205, and the tin layer on the surface of the sealing groove 206 is used to reduce the loss of the sealing block 207, so as to improve the protection of parts such as the valve ball 205 while ensuring the sealing, thereby improving the service life.
