As the further of technique scheme improved and replenish, the utility model also comprises following additional technical feature:
The axis of described valve rod mounting hole and described body cavity axes intersect and vertical.
Described limiting stopper protruding part is provided with two side planes that are parallel to described valve rod mounting hole axis, and these two side planes are vertical mutually, and the distance between the intersection of the intersection of these two side planes and each side plane and valve rod mounting hole inwall equates.
Described limiting stopper is 2, is that center line is symmetrically distributed with described valve rod mounting hole axis.
The fixture block of described valve rod one end is provided with 2 and is parallel to each other and all parallel with valve rod axis plane, and the valve rod the other end is provided with 2 and is parallel to each other and the plane parallel with valve rod axis, and the plane at aforementioned valve rod two ends is vertical mutually.
Described valve rod mounting hole is a step hole, and the aperture of close described body cavity one side is less than the aperture of opposite side.
Be provided with at least one seal ring between described valve rod and the valve rod mounting hole.
Described valve rod erection column outer round surface is provided with screw thread, lid can be installed with the sealing of valve rod mounting hole, is beneficial to the protection of valve rod.
Use the utility model can reach following beneficial effect: limiting stopper of the present utility model can be with the direct drawing of punch press, and valve rod has been cancelled and is used for spacing pin-and-hole, makes structure become simply, and processing becomes is easier to; The dismounting of valve rod is directly inserted or is extracted from the valve rod mounting hole and gets final product, and has avoided installing from body cavity, makes to install to become than being easier to.
