Turn, spool 2 is enable to move up and down by guide thread 11, also can by instruction screw thread 10 while the rotation of guide rod 5
The up and down motion of lifting nut 8 is controlled, so as to indicate the scale on dial gauge 6, can ensure the synchronism of display, adopt
Carrying out control with two different screw threads can avoid influencing each other between spool and lifting nut, can be clearly spool 2
Opening and closing situation fed back in real time on dial gauge 6, indicate screw thread 10 screw pitch for 11 screw pitch of guide thread on guide rod 5
2 times, guide rod 5 rotates a circle, and the distance that spool 2 rises along guide thread 11 is the lift along instruction screw thread 10 of lifting nut 8
From half, lifting situation of the spool 2 in valve body can be more intuitively observed in dial gauge in this way, can be
2 smaller lifting distance of spool is amplified, by indicating that indicating positions of the pointer 7 on dial gauge 6 is indicated, user
It becomes apparent from intuitively understanding state of the spool 2 in valve body.
In use, rotation rotation handle 4 is converted to turning moment and completes descending operation to the thrust of spool 2,
Spool 2 is moved up and down along guide rod 5, observation instruction pointer 7 scale value signified in dial gauge 6, can by scale value
It is apparent from the lifting degree of spool 2；During closing gate valve, handle 4 is rotated by rotation, spool 2 is controlled to fall completely, spool 2
It is fully sealed between valve body 1, flow cannot pass through, and instruction pointer 7 is directed toward the bottommost of dial gauge 6, when opening gate valve, rotation
Rotation handle 4 controls spool 2 to rise, and gap is generated between spool 2 and valve body 1, and when opening completely, spool 2 rises to highest point,
Any interception is no longer played to the flowing of flow, instruction pointer 7 is directed toward the highest point of dial gauge 6.
This specific embodiment is only explanation to the utility model, is not the limitation to the utility model, ability
Field technique personnel can as needed make the present embodiment the modification of no creative contribution after this specification is read, but
