Through adopting above-mentioned technical scheme, the setting of stopper lets the one end of pull rod handle be in the rotating block all the time.

The utility model discloses further set up to: and a spring is arranged between the limiting block and one side of the inside of the rotating block.

Through adopting above-mentioned technical scheme, the setting of spring lets the pull rod handle can not rock and let the inserted block can be steadily in the card is downthehole.

The utility model discloses further set up to: and a set screw is in threaded connection between the valve rod and the rotating block.

Through adopting above-mentioned technical scheme, holding screw can let valve rod and rotatory piece fixed connection, can let both separation after extracting holding screw, the convenient maintenance.

The utility model discloses further set up to: and a sealing ring positioned at the outer side of the valve rod is arranged in the valve body.

Through adopting above-mentioned technical scheme, the setting of sealing washer can increase the tight degree of being connected between valve rod and the valve body.

The utility model discloses further set up to: one end of the pull rod handle is integrally connected with a handle ball.

Through adopting above-mentioned technical scheme, the setting of handle ball can conveniently be controlled the pull rod handle.

To sum up, the utility model discloses following beneficial effect has:

with the outside pulling of pull rod handle, rotatory pull rod handle after that, the pull rod handle will rotate round the axial lead of valve rod, and then drive rotatory piece, the rotation of rotatory piece can drive the valve rod and rotate, thereby it rotates to drive the dish board, thereby realize opening and closing of butterfly valve, after a locating piece removes to another card hole from a card hole, promote the pull rod handle and then drive the fixture block card and go into in the card hole, realize the fixed of pull rod handle, thereby the rotation of restriction dish board, thereby can accurately open and close. The rotating block can not move in the moving process of the pull rod handle, and when the pull rod handle rotates, the rotating block can rotate along with the pull rod handle.
