The technical solution adopted in the utility model is:
A kind of knife gate valve, including valve body, it is critical that the valve body two sides are symmetrical arranged elevating mechanism, the elevator
Structure actuating station is connect with the intracorporal valve plate of valve, and the valve plate has by elevating mechanism and its matched control mechanism to be moved up and down
Freedom degree.
Preferably, including in the elevating mechanism is cylinder.
Preferably, the electric pushrod for including stepper motor in the elevating mechanism and being connect with stepper motor output end.
Further, the valve body is located on pedestal, and the elevating mechanism is mounted on the base.
Further, the elevating mechanism lower end is additionally provided with adjustment bracket.
Further, the valve plate is connect by plate connection frame with the actuating station of two sides elevating mechanism.
Further, the knife gate valve is equipped with sensor in the highest order and lowest order of valve plate stroke.
In above-mentioned technical proposal, a kind of knife gate valve is provided, includes valve body in disconnecting link valve arrangement, is equipped with valve plate, valve in valve body
Plate opening size can control the on-off of fluid, and key Design is, knife gate valve is symmetrical arranged elevating mechanism, lifting in valve body two sides
Mechanism is also mating to be provided with control mechanism, and the actuating station (end) of elevating mechanism is connect with the intracorporal valve plate of valve, in control mechanism
Control under, elevating mechanism drives valve plate connected to it to move up and down, and the adjusting of opening size is formed, to control fluid
On-off.In the structure, elevating mechanism and its control mechanism borrow valve body height, are not take up the unexpected height of valve body height space,
So that knife gate valve entirety occupied space is substantially reduced, it is easily installed.
The beneficial effects of the utility model are: (1) disconnecting link valve arrangement provided by the utility model is simple, ingenious in design, rise
Descending mechanism and control mechanism borrow valve body height, substantially reduce whole height, have saved installation space, extend using model
It encloses;(2) in further improved technical solution, the setting of bottom plate and plate connection frame ensure that the stationarity of knife gate valve work;
The setting of adjustment bracket improves balance when flashboard movement, and convenient for accurate adjustment.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of knife gate valve described in embodiment 2;
In figure, 1, valve body, 1-1, valve plate, 2, electric pushrod, 3, pedestal, 4, plate connection frame, 5, adjustment bracket.
Specific embodiment
The structure and application method of knife gate valve provided by the utility model is described in detail with specific embodiment below, but not
The protection scope of the utility model is limited in any form, and one of ordinary skill in the art repair according to the improvement that technical solution is carried out
