| description | The utility model discloses a vacuum rapid self-closing valve. The vacuum rapid self-closing valve comprises a valve body, wherein an air extraction opening is formed in the top of the valve body. The vacuum rapid self-closing valve further comprises an air pipe and a small ball, wherein the upper section of the air pipe is cone-shaped, an upper valve port is formed in the top of the air pipe, the nearby portion of the upper valve port is screen-clack-shaped, a lower valve port is formed in the lower end face of the air pipe, the inner wall of the valve body is cone-shaped, the cone shape of the upper section of the air pipe coincides with the cone shape of the inner wall of the valve body, the upper section of the air pipe is fixed in the valve body, and the small ball is located in the air pipe. When the vacuum rapid self-closing valve works, the small ball is arranged at the position which corresponds to the screen-clack-shaped portion of the top of the air pipe.
