It is fixedly connected with valve ball, airtight and watertight padding is installed between valve rod and bonnet, the valve body is provided with valve seat keeper, and the valve seat is provided with
The location division being engaged with valve seat keeper；The bellows component that the one end of the valve seat is provided with, the bellows component bag
Include bellows and the sealing shroud being set on bellows；The other end of the valve seat and valve ball are inconsistent, and the end
Leaf spring is arranged with successively and adjustment is enclosed, and the adjustment circle is threadedly coupled with the valve seat；The end face and valve body of the sealing shroud
Madial wall it is inconsistent, other end is inconsistent with leaf spring, when rotation adjustment circle, it is described adjustment circle by leaf spring compress sealing
Set.
It is of the invention further to set：The bellows-sheathed is located on valve seat, and one end and the sealing shroud of the bellows are welded
Fixed, the other end is welded and fixed with valve seat.
It is of the invention further to set：The sealing shroud is provided with gasket seal and fire-protection ring with the inconsistent end face of valve seat.
It is of the invention further to set：The end face of the bonnet towards valve body is fixedly connected with support plate, and the valve rod is passed through
Support plate is fixedly connected with valve ball.
It is of the invention further to set：The location division processes the level table to be formed, valve seat positioning for the lateral wall of valve seat
Part and the level table are inconsistent.
It is of the invention further to set：The location division processes the chute to be formed for the lateral wall of valve seat, and chute is along valve seat axle
Line direction is set, and the valve seat keeper is placed in chute.
Beneficial effect of the present invention：Sealing shroud be set on bellows and by welding be fixedly connected, then together with
Valve seat is welded and fixed to be formed in one loading valve body, then loads valve ball in valve body, and the wherein one end of valve seat and valve ball is inconsistent
Sealed, the other end is sealed by the way that the madial wall of sealing shroud and valve body is inconsistent, because valve seat is also arranged with successively
Leaf spring and adjustment are enclosed, and because the valve body is provided with valve seat keeper, the valve seat is provided with the positioning being engaged with valve seat keeper
Portion, can prevent valve seat from being rotated with respect to valve body, when rotation adjustment circle, and the adjustment circle compresses sealing shroud by leaf spring, together
When valve seat can be done towards valve ball mobile and compress valve ball so that apply close between valve seat and valve ball and between sealing shroud and valve body
Feng Li, plays sealed function, simple in construction, reduction manufacturing cost.
