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 of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a butterfly valve with theftproof function, including valve body 1, the top of valve body 1 is provided with opening mechanism 6, and one side of opening mechanism 6 is rotated and is connected with commentaries on classics 7, and the top of valve body 1 be provided with valve block welded connecting axle 8, the top welding of valve body 1 has connecting pipe 3, and the top welding of connecting pipe 3 has fixed plate 4, the cover is established between connecting pipe 3 and the connecting axle 8, and the inside of connecting pipe 3 is provided with fixed cover 10, and fixed connection between fixed cover 10 and the connecting axle 8, through 5 fixed connection of bolt between fixed cover 10 and the connecting axle 8, fixed cover 10 can be changed, thereby the sunken shape in top to fixed cover 10 changes, the joint between fixed plate 4 and the opening mechanism 6.
