In said structure, the handwheel is rotated, the worm screw rotates together with the driving of the handwheel, due to the snail
Wheel is engaged on the worm screw, therefore drives central axial direction of the worm gear along the valve rod while worm screw rotation
Gyration is done, and drives the valve rod to rotate together with, the valve element is under the driving of the valve rod in the endoporus of the valve body
In realize angles shifts, by handwheel described in forward or reverse, realize gate valve and open a sluice gate or close lock.
In order to further improve the use function of gate valve, the valve body is hollow cylinder, the spacing rib be with it is described
The concentric annulus of valve body inner bore, and be connected as a single entity with the valve body, the interior circular diameter of the spacing rib is less than the valve element
Outside diameter.
In order to further improve the use function of gate valve, the adpting flange is structure as a whole with the valve body, by cast iron
Casting is formed, and mounting hole is provided with the adpting flange.
In order to further improve the use function of gate valve, the valve element upper end is welded with the stem bottom.
In order to further improve the use function of gate valve, the worm gear passes through key connection with the valve rod.
In order to further improve the use function of gate valve, the eccentric bushing is structure as a whole with the overcoat, cast by cast iron
Make and form.
In order to further improve the use function of gate valve, the handwheel is connected with the worm screw by spline, and has tightening
Screw lock.
Beneficial effect is：Coordinated by the worm gear and the worm screw, the handwheel is changed into side by top installation
Face is installed, and is substantially reduced the height of gate valve, is effectively avoided severing the handwheel in use.
