Abstract
The utility model discloses a driving structure of a knife gate valve, which comprises a valve body. The two ends of the valve body are respectively an inlet end and an outlet end. A valve seat is installed on the valve body. A valve stem penetrates through the valve seat. The lower end of the valve stem is connected with a knife-shaped valve plate. The upper end of the valve stem is a worm. The worm is engaged with a worm wheel in a driving way. The external part of the worm wheel is connected with a driving hand wheel. Since the knife-shaped valve plate is used as a gate, the structure design is simple, the driving structure of the knife gate valve is convenient to manufacture, the sealing performance is good, and the working stability of the gate valve can be ensured.
Description
Technical field
The utility model relates to valve field, specifically belongs to the drive mechanism of cutter type gate valve.
Background technique
The open-shut device of the drive mechanism of cutter type gate valve is a flashboard, and the moving direction and the flow direction of flashboard are perpendicular, and gate valve can only be made standard-sized sheet and complete shut-down, can not do to regulate and throttling.Flashboard has two sealing surfaces, and two sealing surfaces of the most frequently used pattern gate valve form wedge shape, and different, the flashboard of Wedge gate valve can be made an integral body to key groove with the valve parameter, is called the rigidity flashboard; Also can make the flashboard that can produce micro-deformation, to improve its manufacturability, remedy the deviation that the sealing surface angle produces in course of working, this flashboard is called Flexible disc.
The model utility content
The purpose of this utility model provides the drive mechanism of cutter type gate valve, and structural design is simple, and is easily manufactured, and good seal performance has guaranteed the stability of gate valve work.
The technical solution of the utility model is as follows:
The drive mechanism of cutter type gate valve includes valve body, and two ends of valve body is respectively entrance point, outlet end; Valve seat is installed on the valve body, has passed valve rod in the valve seat, the lower end of valve rod connects the valve plate of knife-edge, and the upper end of valve rod is a worm screw, and worm drive is engaged with worm gear, and worm gear is externally connected with the transmission handwheel.
The utility model adopts the valve plate of knife-edge as gate, and structural design is simple, and is easily manufactured, and good seal performance has guaranteed the stability of gate valve work.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
