According to a kind of flat gate valve with limited location groove of one embodiment of the present utility model, specific works mode is such as
Under：Flat gate valve as shown in Figure 1 is in opening, due to the first stopper slot 601, the second stopper slot 602 and the 3rd limit
Position groove 611 setting, have certain gap between the inclined-plane of main gate-board 60 and auxiliary gate-board 61, the bearing pin 612 on auxiliary gate-board 61 with
The lower end of gathering sill 603 offsets, while the limited block 610 on auxiliary gate-board 61 leans with bonnet 1, main gate-board 60 can be relative to
Auxiliary gate-board 61 is moved a certain distance, and when needing to be closed flat gate valve, rotates handwheel 5, and handwheel 5 is promoted with ovable valve stem 3
Main gate-board 60 starts to move downward, due to the presence in gap between main gate-board 60 and auxiliary gate-board 61, now 3 promotion main switch of valve rod
Plate 60 is moved downward, and as main gate-board 60 is moved downward, the gap between main gate-board 60 and auxiliary gate-board 61 is progressively smaller until master
It is brought into close contact between flashboard 60 and auxiliary gate-board 61, now the bearing pin 612 on the upper end of gathering sill 603 of main gate-board 60 and auxiliary gate-board 61
Offset, main gate-board 60 starts to drive auxiliary gate-board 61 while moving downward, when main gate-board 60 runs to terminal downwards, main gate-board 60
Both sides strut the main gate-board 60 for being with the axial force of the inclined-plane generation horizontal direction of auxiliary gate-board 61 to the left and right with auxiliary gate-board 61, are formed
Compression seal, valve closing, now the center line of pod apertures occurs one on the center line of the pod apertures of main gate-board 60 and auxiliary gate-board 61
Fixed deviation；During valve opening, active handwheel 5, handwheel 5 is rotated with ovable valve stem 3, and valve rod 3 drives main gate-board 60 to move upwards, extremely
When the center line of the pod apertures of main gate-board 60 overlaps with the center line of the pod apertures of auxiliary gate-board 61, main gate-board 60 drives auxiliary gate-board 61 together
Motion upwards, run up until lower end and the bearing pin 612 of gathering sill 603 offset, limited block 610 and bonnet on auxiliary gate-board 61
61 when leaning, and pod apertures 62 overlap with valve seat 4, and flat gate valve is in the state for fully opening, limited block 610, gathering sill 603
And the setting of bearing pin 612 can ensure to be completely superposed between pod apertures 62 and valve seat 4, it is to avoid between pod apertures and valve seat
The generation of dislocation, when being moved to full open position, the spacing groove between main gate-board 60 and auxiliary gate-board 61 causes main gate-board 60
It is softened between auxiliary gate-board 61 and has certain gap, while main gate-board 60 is also limited and stop motion by auxiliary gate-board 61.
Although embodiments of the invention have been shown and described above, it is to be understood that above-described embodiment is example
Property, it is impossible to limitation of the present invention is interpreted as, one of ordinary skill in the art within the scope of the invention can be to above-mentioned
Embodiment is changed, changes, replacing and modification.
