Description
Technical field
The utility model relates to valve mounting technology field more particularly to a kind of valve screw-driving apparatus.
Background technique
Most of valves with replaceable sealing pair formula, the position fixation of sealing pair is all by a certain number of spiral shells
What nail was realized, with the increase of valve aperture and rated pressure, the fixing screws quantity and size of sealing pair are also all increase accordingly.
In order to guarantee the reliability of valve seal, the rundown process of these screws can all require the torque for having certain, torque value it is big
Small and uniformity can all produce a very large impact the sealing performance of valve, such as: excessive screw torque can make sealing pair group
Part and screw itself are easily deformed, and when bearing the dynamic loading of medium, life of valve significantly shortens；Screw torque is insufficient or
It is unevenly distributed, and sealing pair discontinuity equalization can be made, optimal valve seal state when design is not only not achieved, or even can make
At the leakage of valve, its sealing function is made to fail.It is inclined for soft, the hard sealing for directly relying on the screw torque to keep sealing performance
For heart butterfly valve, the accuracy of torque then seems even more important.
But at present due to the architectural characteristic of valve itself and many and diverse type, the tightening to be substantially of this kind of screw passes through hand
Formula torque wrench or some easy wrest fixing spanners are held to realize.Operator is wanted in such a way that spanner manually tightens screw
It asks higher, is difficult to obtain accurate screw-driving data, artificial rundown process must have higher sense of responsibility, should anti-leak-stopping
It twists, also to keep uniformly slowly tightening speed, prevent output torque to be deteriorated, otherwise it is difficult to ensure that the stress of screw is equal
It is even；Screw needs tightening for more rounds that can just tend towards stability, large labor intensity, inefficient.It is deposited in operation as it can be seen that actually tightening
The overall performance of valve is reduced so that the fixation of valve seal pair inevitably has risk in numerous uncertainties.
