When the sealing valve seat 13 completely enters the inside of the valve body 1, the snap ring 15 is pressed to make Its top is lower than the top of the mounting ring 14, and then the mounting ring 14 is continued to be squeezed. When the snap ring 15 is in the mounting groove 11 inside the valve body 1, the strong spring 16 inside the mounting ring 14 begins to rebound, causing the snap ring 15 to enter the mounting groove 11, limiting the mounting ring 14 and the sealing valve seat 13, and then rotating the valve core 12 to realize the operation of the valve. The first guide angle 17 plays a guiding role when the first guide angle 17 enters the interior of the valve body 1. When the valve seat is in use, as the use time increases, its own sealing performance will gradually decline and needs to be replaced. However, the steps for installing the valve seat are cumbersome, so the sealing valve seat 13 is allowed to enter the interior of the valve body 1 by squeezing the mounting ring 14, and then the sealing valve seat 13 is limited by the cooperation between the mounting groove 11 and the snap ring 15, making the steps for installing the sealing valve seat 13 more convenient and increasing the efficiency of installing the sealing valve seat 13.
