Description
Technical field
This utility model is related to a kind of valve actuator field and in particular to a kind of held based on the valve of gas-liquid cluster spring
Row device.
Background technology
Valve actuator is the drive mechanism realizing valve opening or closing, its structure generally comprise power executive item,
Execution casing, and spring cylinder, operating mode typically in case of emergency uses in technique and pipe applications system, is occurring promptly
When situation, when control system loses power supply or source of the gas again simultaneously, single-acting actuator can automatically reset, and drives valve
Door to the failsafe position being pre-designed, thus whole device potential danger is preferably minimized.Single-acting executor is typically
With the energy of the metal spring storage of compression, UPS emergency power supply or accumulator tank, other store in advance to also have weight etc.
Energy is used as the power of 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.
But situation in actual applications is, pipeline valve more and more more uses heavy caliber, high pound level high pulling torque, different
Open in the case of often or close these quick action emergency valves, we are got over as the valve actuator of supporting needs using conventional springs
Come more inadaptable：Weight is heavy, volume is big, take up room, spring is chronically at pressured state, and rigidity reduces, elastic force reduces, appearance
Fatiguability inefficacy, camber of spring, motion abnormal sound, even occur spring fracture major accident.Difficult, manufacture process is changed at scene
The middle consumption energy.
Following defect is primarily present as the valve actuator (as shown in Figure 1) of supporting needs using conventional springs cylinder：
1. the executor's spring cylinder driving large scale valve is always a difficult problem：Quality weight, volume is big, take up room,
Waste of resource.
2. the work characteristics according to single-acting spring executor, spring is chronically at compressive state, and easy compression goes out
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 changed at the scene once needing and keeped in repair just become very can not possibly or very
Difficult.
