[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0006] The bellows ball valve comprises a ball valve body, a first flange plate, a metal bellows, a second flange plate, an extension plate and an extension adjusting mechanism. The right end of the ball valve body is fixed with the first flange plate. The left side of the ball valve body is fixed with the metal bellows. The left end of the metal bellows is fixed with the second flange plate. The lower side of the ball valve body is fixed with the extension plate. The extension plate is installed with the extension adjusting mechanism for driving the extension of the second flange plate and the metal bellows. The extension adjusting mechanism comprises a threaded sleeve, a threaded rod, a support frame and a limiting guide rod. The threaded sleeve is rotationally connected to the extension plate. The threaded sleeve is installed with the threaded rod penetrating through it. The front end of the threaded rod is fixed with the support frame. The upper end of the support frame is fixed with the second flange plate. The threaded rod is fixed with the limiting guide rod penetrating through the extension plate.

[0007] Preferably, the limiting guide rod is slidingly connected with the extension plate.

[0008] Preferably, the outer side of the threaded sleeve is fixed with a rotating handle.

[0009] Preferably, the metal bellows is made of stainless steel.

[0010] The utility model discloses a beneficial effect is: the bellows valve, when using, rotates the handle and drives the threaded sleeve rotation with hand, and the threaded sleeve rotation drives the threaded rod movement, moves through the threaded rod and drives the support frame, moves through the support frame and drives the second flange plate, and the metal bellows telescopic is driven through the second flange plate movement, thereby adjusting the length of the whole, to satisfy different installation demand.
