Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
The blocking device for preventing valve from opening certainly as shown in figures 1 to 6, is installed in shut-off valve valve door rod 1, door rod 1
On be provided with keyway 11 and be located in door frame 4, be set with the differential 5 of sealed valve in door rod 1, the lower section of differential 5 is equipped with packing, closes
Locking device includes fixation kit 2 and positioning key 3, and fixation kit 2 includes that card embraces the tiles armful plate 21 of door rod 1, connection bolt 22
With baffle 23, two outsides for embracing plate 21 are respectively welded with a connecting plate 24, the company of insertion connection bolt 22 are provided on connecting plate 24
Hole is connect, is opened on baffle 23 there are two bolt hole corresponding with connection bolt 22, connection bolt 22 is inserted into the connection of connecting plate 24
The bolt hole of hole and baffle 23 makes an armful plate 21 be connected with baffle 23, is screwed into bolt in the bottom of connection bolt 22, makes to embrace a plate 21
It is fastened with baffle 23, one end end point of positioning key 3, which is inwardly cut, forms plush copper 31 and step 32, and positioning key 3 is inserted in keyway 11
It is interior, step 31 is stuck on the edge of 5 inner circle of differential in the gap that plush copper 31 is inserted between door rod 3 and differential 5,23, baffle
In positioning key 3 outside and be in contact with positioning key 3.
After dismantling Electric Actuator, positioning key 3 is first caught in keyway 11, slide downward positioning key 3 makes plush copper 31 be inserted into door
