Description
Technical field
This utility model is related to a kind of valve actuator field and in particular to a kind of driving based on gas-liquid cluster spring fills
Put and valve actuator.
Background technology
Executor is the control actuator that valve opening is closed, and its structure generally comprises power executive item, execution casing,
And spring cylinder, operating mode typically in case of emergency uses in technique and pipe applications system, be in an emergency when
Wait, when control system loses power supply or source of the gas, single-acting actuator can automatically reset simultaneously again, drive valve in advance
The failsafe position of design, thus be preferably minimized whole device potential danger.Single-acting executor is typically with compression
The energy of metal spring storage, UPS emergency power supply or accumulator tank, other energy of storing in advance such as weight are also had to make
Power for actuator driven.The metal spring of wherein compression is using a kind of most actuator driven modes.
Executor's spring cylinder is a kind of elasticity using compression spring come the mechanical component of work.Spring is to use elastomeric material
The part made, deforms upon under external force, restores to the original state after removing external force again.Spring is typically made with spring steel.With
The raising of system safety integrity level and the continuous lifting of executor's general safety level, the spring as valve actuator will
Ask and also must have enough mechanical lives, fatigue strength and reuse the life-span, the serious thing of spring breakage can not occur
Therefore.

Existing spring fatigue, spring loses original elasticity, reduces the reliability of in emergency circumstances action.
3. normal use during with use time passage and action frequency increase, spring can fatigue failure, thrust by
Step reduces or reduces.Executor's Reliability of Microprocessor and rich safety coefficient reduce continuous.
4. the strength of the spring that executor needs cannot be carried out precise quantification process, and the time of driving valve and speed can not
To finely control.Spring determines that, spring force can not possibly adjust, and unlikely increases once shaping power output.
5. spring is easily deformed and produces abnormal sound, gives people to cause unsafe psychological burden；Executor's spring breakage is also
Happen occasionally.
6., due to the work characteristics of single-acting executor, spring must also have considerable amount of power to drive valve when exporting on earth
Door, therefore conventional metals spring cylinder need special tooling compression assembling, efficiency of assembling, assembling when being assembled to above executor
Risk is big.
7. spring cylinder component is changed at the scene once needing and keeped in repair just becomes very impossible or very difficult.
