Description
Technical field
The present invention relates to a kind of valve actuator fields, and in particular to a kind of valve execution based on gas-liquid cluster spring
Device.
Background technology
Valve actuator is the driving mechanism for realizing valve opening or closing, structure generally comprise power executive item,
Babinet and spring cylinder are executed, operating mode generally in case of emergency is occurring promptly using in technique and pipe applications system
When situation, while when control system loses power supply or air source again, single-acting executing agency can automatically reset, and drive valve
Door is to the failsafe position being pre-designed, to which whole device potential danger is preferably minimized.Single-acting executor is typically
The energy, UPS emergency power supplies or the accumulator tank that are stored with the metal spring of compression, also having weight etc., other are stored in advance
Energy is used as the power of actuator driven.The metal spring wherein compressed is a kind of most commonly used actuator driven mode.
Actuator spring cylinder is a kind of elasticity using compressed spring come the mechanical component of work.Spring is to use elastic material
Manufactured part, deforms upon under external force, restores to the original state again after removing external force.Spring is generally made of spring steel.With
The continuous promotion of the raising and actuator general safety level of system safety integrity level, the spring as valve actuator is wanted
Enough mechanical lives, fatigue strength must be had and reuse the service life by asking also, and the serious thing of spring breakage can not occur
Therefore.
However in practical applications the case where, is, pipeline valve is more and more using heavy caliber, high pound grade large torque, different
These quick action emergency valves are opened or close in the case of often, we are got over using conventional springs as the valve actuator of mating needs
Come more inadaptable：Weight weight, volume are big, occupied space, spring are chronically at pressured state, and rigidity reduces, elastic force reduces, is easy
Fatigue failure, camber of spring, movement abnormal sound, the major accident that spring fracture even occurs.It replaces in difficult, manufacturing process at scene
Consume the energy.
Valve actuator using conventional springs cylinder as mating needs（As shown in Figure 1）It is primarily present following defect：
1. it is always a problem to drive the actuator spring cylinder of large scale valve：Quality weight, volume be big, occupied space,
Waste of resource.
2. according to the work characteristics of single-acting spring actuator, spring is chronically at compressive state, is easy compressive deformation,
There is spring fatigue, spring loses original elasticity, reduces the reliability in emergency circumstances acted.
3. as usage time elapses and acts the increase of frequency during normal use, spring can fatigue failure, thrust by
Step reduces or reduces.Actuator Reliability of Microprocessor and rich safety coefficient are constantly reducing.
4. the strength of spring that actuator needs can not carry out precise quantification processing, drive valve time and speed not
It can finely control.Spring determines that spring force can not possibly adjust, and unlikely increase once shaping power output.
5. spring is easily deformed and generates abnormal sound, to artificial at unsafe psychological burden；Actuator spring breakage is also
It happens occasionally.
6. must also have considerable amount of power drive valve due to the work characteristics of single-acting executor, when spring is output to bottom
Door, thus conventional metals spring cylinder is assembled to above actuator when need special tooling compression assembly, efficiency of assembling, assembly
Risk is big.
7. spring cylinder component becomes very once needing to be replaced and repaired at the scene it is not possible that very
It is difficult.
