[0019] In specific embodiments, referring to Figure 1 、 Figure 2 , valve hole 31 is table type, plug body 6 is disc-shaped, and the edge of plug body 6 close to valve hole 31 is provided with an inverted bevel 61. In the application, valve hole 31 is table type, the caliber of one end of valve hole 31 close to drive mechanism 4 is smaller than the caliber of one end of valve hole 31 close to plug body 6, the diameter of plug body 6 is between the caliber of two ends of valve hole 31, plug body 6 enters valve hole 31 from the larger caliber and gradually reduces the distance with the inside of valve hole 31, and finally completely plugs valve hole 31, the inverted bevel 61 of the edge of plug body 6 is used for guiding plug body 6 into valve hole 31.

[0020] In specific embodiments, referring to Figure 1 、 Figure 2 , plug body 6 is located on one side of partition layer 3 away from drive mechanism 4. In the scheme, plug body 6 can be located on both sides of partition layer 3, and in the application, plug body 6 is located on one side of partition layer 3 away from drive mechanism 4, so that plug body 6 can pass through partition layer 3 when drive mechanism 4 is retracted, which can ensure the stability of plug body 6 plugging valve hole 31.

[0021] In specific embodiments, referring to Figure 1 、 Figure 2 , the middle part of plug body 6 is connected with a rod body 91, one end of rod body 91 close to drive mechanism 4 is hinged with the end of drive rod 5, and the end of drive rod 5 of drive mechanism 4 is hinged with plug body 6, which can realize universal function. Universal joint or spherical rotating part can be used to realize universal function.

[0022] In further embodiments, referring to Figure 1 、 Figure 2This design employs a spherical rotating component. The end of the drive rod 5 is provided with a cap 51, which has a first hemispherical groove 511 facing the plug 6. The cap 51 is connected to a cover 52 with a second hemispherical groove 521. When the cover 52 and the cap 51 are closed, they form a movable groove. The cover 52 is also provided with a hole 522 communicating with the movable groove. The rod 91 passes through the hole 522 and is located in the movable groove and is connected to the ball 92. In this design, the first hemispherical groove 511 and the second hemispherical groove 521 can be spliced ​​to form a complete spherical groove. The ball 92 connected to the end of the rod 91 is located in the complete spherical groove. The diameter of the hole 522 is larger than the diameter of the rod 91 but smaller than the diameter of the spherical groove. Therefore, the rod 91 can rotate omnidirectionally relative to the spherical groove under the action of the ball 92.

[0023] In a specific embodiment, refer to Figure 1 , Figure 2 An elastic element 7 is fitted onto the rod 91 on the side of the plug 6 away from the drive mechanism 4.

The two ends of the elastic element 7 respectively abut against the nut 8 and the side of the plug 6 away from the drive mechanism 4. In this solution, the contraction of the drive device requires controlling the plug 6 to close or open. However, when controlling the plug 6 to close, there is no buffering effect. That is, if the plug 6 is already tightly closed, excessive closure may cause the plug 6 to get stuck in the valve hole 31. In this solution, when the drive mechanism 4 contracts, the plug 6 is already tightly closed with the valve hole 31. Excessive contraction of the drive mechanism 4 will compress the elastic element 7 and buffer it within the elastic element 7, preventing the plug 6 from being over-closed and improving stability.
