Description
Technical field
It the utility model is related to a kind of fluid of the field apparatus for technique productions equipment and make dynamic formula drive device, such as gas
Pressure type driving device or fluid pressure type driving device and especially stroke driving device (Hubantrieb).Technique productions equipment is for example
It is chemical plant and especially petrochemical plant, power plant, food technology production equipment such as brewery etc..Fluid makees dynamic formula drive device
This is designed for the regulating valve for adjusting field apparatus, and operating physical force is produced such as control valve and/or safety valve.Fluid makees dynamic formula
Drive device includes at least one working chamber, that it can receive fluid and preferably air pressure or hydraulic regulation pressure, to provide use
In the pressure component of operating physical force, the fluid makees drive rod or the drive that dynamic formula drive device also includes extending from these drive devices
Moving axis, to adjust the regulating valve by operating physical force.
Background technology
Making dynamic formula drive device in the fluid of stroke driving device form has drive rod, and drive rod can mainly extend at it
Translational movement from drive device by operating physical force to be transferred to regulating valve on direction.Device for revolving and driving possesses drive shaft, and it can be around
Its axis is rotated so that operating physical force is transferred into regulating valve as operational torque from device for revolving and driving.Fluid makees dynamic formula drive device
Including at least one working chamber, working chamber can receive fluid, such as the process fluid of air pressure or hydraulic pressure, to produce relative to ring
The pressure difference of border pressure and/or the second operating pressure being present in the second working chamber, and will act on fluid and make dynamic formula driving
Pressure difference on the acting surface of device is converted to the adjusting force or operating physical force for adjusting the regulating valve.
Drive device housing can be had according to the air pressure adjustment drive device of foreword, housing includes acceptable pneumatic fluid
Driving chamber and reseting cavity provided with compression spring.Generally, working chamber is opened by drive disk and barrier film with reseting cavity seal interface
And compression spring is provided with reseting cavity, on the one hand the compression spring is supported in an inner walls and on the other hand supported
On drive disk.The drive rod of common regulation drive device is so permanently connected with drive disk position, i.e. drive rod is without prolonging
Behindhand follow each motion of drive disk.The action direction of compression spring corresponds essentially to the longitudinal direction of drive rod, and drive rod can be
The longitudinally upper transverse movement.Drive rod extends through working chamber and the housing of air pressure adjustment drive device from drive disk.Bar connects
Drive rod can be connected by part with adjusting rod, and regulation valve member is provided with adjusting rod.Regulation valve member is consolidated generally relative to position
Fixed valve seat can also transverse movement, therefore valve seat and valve member define valve aperture area, and it depends on valve element position and can be
Moved between closure state and full open position, under full open position, it is transversal that open cross-section can correspond to valve seat
Face.
Such regulation drive device can be with so configured, i.e., compression spring is directed to valve member closing fortune in reseting cavity
It is dynamic, until the completely closed state of regulating valve.Utilize the air pressure process fluid in the working chamber of known regulation drive device
Atmospheric pressure can be produced, its action direction is opposite with the spring force of back-moving spring so that valve member enters open position from closed mode
Put.That is, the operating physical force of valve member is acted on from regulation drive device can typically be divided into pressure component and spring force component substantially, should
Pressure component by working chamber pressure work pressure produce, the spring force component depend on back-moving spring spring constant and from
The spring travel that its unloaded position rises.Operating physical force can enter opening position by entering the sealing of drive device housing in drive rod
Perhaps adjusting rod influences into the sealing of valve body into the frictional force of opening position.In regulating valve to be added on valve seat upper and lower
Under differential pressure conditions between the part of trip, the operating physical force of the regulation drive device is on closed position with acting on the pressure of valve member
Act on the contrary.The measuring force acted on due to the measurement of such as drive rod position of position sensor is compared to the pressure for valve member
Power and small several orders of magnitude of frictional force on sealing are appeared in, and the operation for valve is actually meaningless.
Need reliably to seal in the completely closed state of valve, the power applied by process fluid is less than the behaviour for acting on valve member
Make power.Therefore back-moving spring must be suitable to be pre-compressed enough in drivingly maximum unloaded state at it on closed position
Spring travel to provide required closing force.When the fluid using the two-way function without spring return function function makees dynamic formula driving
During device, the minimum differntial pressure between two working chambers for producing closing force is always needed in closure state to provide
The closing force needed.
In order to which by opening the valve according to the drive device of foreword, it is necessary to which the driving chamber provides air pressure force component, its is big
In the reset adjusting force of back-moving spring, back-moving spring is compressed under the maximum open mode of adjusting means with spring travel, should
Spring travel corresponds to valve member regulation stroke plus the back-moving spring pretensioned spring stroke required for safety shutdown.
Such as DE102010014668A1 describes a kind of known air pressure adjustment driving dress for being used to adjust regulating member
Put.The structure space of known air pressure adjustment drive device is decisively determined by back-moving spring axial length and in working chamber
The acting surface that pressure difference between environmental pressure or another working chamber is acted on, i.e. such as drive disk.It fact proved, air pressure adjustment
The required structure space of drive device is reduced, without reducing available closing force and available regulation stroke.
