In valve rod upper end, be coaxially installed with controller housing, this controller housing upper end is coaxial installs transparent indicator window, indicator window radially on the control shell of one end one be shaped with the arrow of a convex; In the controller housing of dial below, be coaxially installed with an one-sided cam, this one-sided cam is radially provided with a resilient contact in the controller housing of a side, the sidewall contact of this resilient contact and one-sided cam by this one-sided actuated by cams;
One worm gear drive switch is installed on the valve rod between described rack plate and valve positioner, and this worm gear drive switch adopts worm gear structure, and the free end level of worm screw is stretched out worm gear drive switch and drive motor is installed.
And described valve plate bottom is provided with a trimming bolt.
And the middle part, valve plate surface of described valve rod both sides all symmetry is shaped with a stiffening rib.
Advantage of the present utility model and good effect are:
1, the utility model valve plate and valve rod are fixedly mounted with and can regulate by trimming bolt, guarantee that the indication of valve plate and valve rod end is accurate in the same way, and indication is accurate, thereby guarantee that the angle control accuracy of valve is high.
2, the utility model adopts the kiss-coating valve seat of moulding by casting, valve seat two ends are all shaped with the flanging affixed with valve body, can effectively guarantee axial stability and the sealed precision of valve seat, avoid because of the long-term loosening problem of valve seat that causes of using, extend valve working life.
3, valve rod of the present utility model coordinates with lock collar, is convenient to accurately control opening angle, simple in structure, easily controls, and helps operator to be more prone to grasp flow situation, and simple in structure, and the installation of valve part is simple, long service life.
