Detailed Description

Because current electronic airtight valve inner structure is all comparatively accurate, but application scope is smaller, and the long dust of live time gathers easily in airtight valve to influence inside control circuit, use very inconvenient, in order to solve above-mentioned problem, the utility model provides a novel electronic airtight valve.

The present invention is described in detail with reference to the accompanying drawings, as shown in fig. 1-3, the electric sealing valve mainly includes a sealing valve body 1, a rotating shaft 5 inserted into the sealing valve body 1, and an electric actuator 3 connected to the rotating shaft 5, wherein the connecting portion between the rotating shaft 5 and the sealing valve body 1 is provided with a shaft sleeve 8, so as to ensure that the rotating shaft 5 can smoothly rotate on the sealing valve body 1, inside the sealing valve body 1, a plurality of connecting rod members 6 for fixing the blades 7 are provided on the rotating shaft 5, the connecting rod members 6 are arranged side by side on the sides of the blades 7, and are fixedly connected to the rotating shaft 5, one end of the rotating shaft 5 outside the sealing valve body 1 is prism-shaped, so as to facilitate the connecting of the rotating shaft 5 and the electric actuator 3, the rotating shaft 5 is driven to rotate by the electric actuator 3, thereby driving the blades 7 to rotate by the connecting rod members 6, so that the blades 7 completely block up the sealing valve port, and play a role of sealing.
