Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, an anti-leakage self-sealing valve includes a valve body 1, wherein a valve driver 2 is disposed at the top of the valve body 1, wherein flanges 3 are fixedly mounted on both sides of the valve body 1, wherein an inner wall of the flange 3 is provided with a mounting groove 4, wherein a pipe 6 is fixedly connected to the inside of the mounting groove 4 through bolts 5, wherein a left end of the pipe 6 extends to the inside of the mounting groove 4, wherein a humidity sensor 7 is fixedly mounted below the outer side of the flange 3, wherein a cavity 8 is formed in the flange 3, wherein a dividing block 9 is fixedly mounted in the cavity 8, wherein the cavity 8 is divided into three regions by the dividing block 9, each region corresponds to a discharge pipe 12, wherein a through hole 10 is formed in the dividing block 9, wherein an injection nozzle 11 communicated with the cavity 8 is embedded in the outer side of the flange 3, and the injection nozzle 11 is located at the middle, wherein, the inner wall of the flange 3 is embedded with a discharge pipe 12 communicated with the cavity 8, wherein, the interior of the discharge pipe 12 is embedded with a micro electromagnetic valve 13, wherein, the discharge pipe 12 and one end positioned at the cavity 8 are fixed with a hose 14, the hose 14 ensures that the hose 14 can extend into the filling agent when the flange 3 is installed in any direction.
