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, the present invention provides a technical solution: a leak-proof self-adaptive safe stainless steel butterfly valve comprises a valve seat 1, wherein a valve plate 2 is rotatably mounted in the valve seat 1, a connecting part 3 is arranged at the top of the valve seat 1, a valve rod 4 is rotatably mounted in the connecting part 3, the bottom of the valve rod 4 extends into the valve seat 1 and is welded with the top of the valve plate 2, an adjusting disc 5 is welded at the top of the valve rod 4, mounting grooves 6 are formed in the inner walls of two sides of the connecting part 3, and a self-adaptive structure 7 is arranged in each mounting groove 6;
self-adaptation structure 7 includes two drums 701 and two slide bars 702, the same mounting panel 703 is installed in the rotation on slide bar 702, one side of mounting panel 703 is equipped with sealing strip 704, slidable mounting has telescopic link 705 on the inner wall of one side of drum 701, spring 706 and roof 707 have been welded respectively to telescopic link 705's both ends, the top and the bottom of roof 707 respectively with two slide bar 702 sliding connection, the steady movement of mounting panel 703 can be guaranteed in the setting of slide bar 702, sealing strip 704 is close to the convex of one side of valve rod 4, and sealing strip 704 is made by rubber, be equipped with the round hole on the mounting panel 703, round hole inner wall and slide bar 702 sliding connection, the welding has the baffle between spring 706 and the telescopic link 705, the top and the bottom of baffle all are equipped with the ball, two balls are in the same place with the top inner wall and the bottom inner wall laminating of drum 701 respectively, the bottom welding of adjustment disk 5 has a plurality of connecting rods, the bottom of a plurality of connecting rods all welds with valve rod 4.
