Lower movement, meanwhile, the scale when pointer on scotch 9 can be with indicating closing can record scale at this time and use convenient for next time；
When the lower end of screw rod 15 moves down, the compressed power of disc spring 18 deformation, the downward active force of screw rod 15 is transmitted to
On valve rod 2, valve rod 2 is moved down, by engaging for spool 4 and valve seat 3, to achieve the purpose that valve is closed；
When valve opening, the rotation hand wheel 11 counterclockwise under the action of bearing 13, ut socket 12 can be with handwheel 11
Rotation counterclockwise, and ut socket 12 can drive feed screw nut 16 to rotate counterclockwise, upper end and lead screw spiral shell due to lead screw 15
Female 16 threaded engagements, lower end are fixedly connected with housing 17 is connect, when feed screw nut 16 rotates, due to feed screw nut 16 and silk
The screw thread of bar 15 be it is left-handed, therefore, screw rod 15 can only move up, and connect housing 17 and scotch 9 also simultaneously to
Upper movement；
When the lower end of screw rod 15 moves up, drive connection housing 17 moved up with scotch 9, connect housing 17 and
The holding effect of divided ring 10 drives the valve rod 2 being fixedly connected with divided ring 10 to move up, and is detached from spool 4 and valve seat 3
Engagement, to achieve the purpose that valve is opened；The pointer on scotch 9 can indicate scale when opening at this time, can record this
Shi Kedu uses convenient for next time.
The utility model has the advantage that compared with prior art are as follows:
A, when pipeline pressure fluctuates or when valve is using electronic, pneumatic and hydraulic executer or mechanical wear
When, the power up pushed up may make sealing be not closed completely, but due to there is disc spring external force, can rise to the sealing of spool, valve seat
Compensating action makes spool, valve seat be in sealing state always, can increase leakproofness, the expanded service life of valve；
B, two sections of stem designs are convenient for applying external force to valve rod, because valve rod and screw rod are self-existent；Make valve rod just
In processing, intensity is good, and bending resistance is big；Easy to repair, disassembly, replacement；
C, the design of pressing sleeve formula valve cage not only guarantees the airtightness of valve internal, can also replace to the valve seat of abrasion,
When the prooving of valve seat it is larger cannot in use, valve need not be bought again, as long as and replace valve seat, saved and be replaced with
This；The design of pressing sleeve formula valve cage can be applicable to sizes, model, the shell of shape, valve body, realize the effect of multi-purpose valve
Fruit can reduce use cost；
