Description
The application is for to enjoy the applying date be on March 7th, 2006 and be called the dividing an application of application number 200680054515.3 of " for valve acutator generates electricity ".
Technical field
Present invention relates in general to valve acutator (or valve actuator), more particularly, be related to the electronic equipment generating of described valve acutator.
Background technique
Valve acutator is used to control valve, and with various shape, size, form is manufactured, and serves many purposes.For the operator of valve acutator, usually wish to understand the particular location of valve.Already absolute encoder and incremental encoder were applied on the valve acutator, to determine the position of valve.The position of the described valve acutator of described encoders monitor is in order to determine the corresponding position of valve.
Absolute encoder is used for the graphical symbol of uniqueness each position of valve acutator.Absolute encoder generally includes single disk or a plurality of disk, and these disks are rotated when valve acutator moves to diverse location.The single or multiple disks of absolute encoder have a plurality of marks, and the different combination of these marks provides the graphical symbol of uniqueness of each position of valve acutator.Can analyze at any time the graphical symbol of this uniqueness, to determine the position of described valve acutator.
On the other hand, incremental encoder does not possess the graphical symbol for the uniqueness of each position of described valve acutator.Means as an alternative, the described valve acutator of incremental encoders monitor are the variation of starting point relatively arbitrarily, such as the position of the complete closure of valve.Incremental encoder is known as again the relative coding device, and it can be the single disk that a series of repeating labels are arranged around the edge of disk.When described disk is rotated, one of them mark is arranged at every turn by a point, the change of record position.For example, if disk has 100 marks around the edge of this disk, this disk just can rotate repeatedly, and therefore can add up hundreds of marks, with the change of indicating positions.As long as described mark is recorded in the storage of computer, then just can understand the position of described valve acutator, and can be presented in the readable data register of user or the data bit on Alpha's digital display by the airborne electronic equipment device that uses status contact.
Valve acutator also has dashboard (or steering wheel) usually, breaks down or occurs in the situation of power failure at motor, so that can carry out manual operations to described valve.But, the position indication that runs out of steam and can lead to errors, if described dashboard is moved, simultaneously outage, and the words that do not have back-up power or redundant power to supply with.After described dashboard was moved, the shortage of renewal may cause valve acutator to indicate a kind of position, and simultaneously, in fact described valve is in different positions.Use the actuator of absolute encoder when power recovers, automatically to correct as early as possible the indication of described position.Use the actuator of incremental encoder must have back-up power or redundant power supply, in order to allow them to avoid the overall forfeiture of location status being understood in outage.For this situation, when losing electric energy (or power), incremental encoder or recover its initial position, or its magnitude of current is kept at the non-volatile memory location of the electronic equipment that carries.If described dashboard is moved in the incremental encoder system, described electronic equipment can continue to follow the tracks of described position, as long as described back-up power or redundant power are remained valid.But, if back-up power or redundant power exhaust (for example, the battery of inefficacy), will lose correct perception to the position based on the actuator system of incremental encoder so, if user's mobile operating dish after back-up power or redundant power exhaust.Conversely, incorrect position information may cause again the damage of valve and the incorrect operating process of being controlled by described valve.Can keep correct position information when the loss of normal power based on the system of absolute or incremental encoding type, as long as possess back-up power or redundant power.The absolute coding system also may lose the ability of its indicating correct position during total power forfeiture, but, it can recover when recovering power at once.On the other hand, described incremental system need to be proofreaied and correct after total loss of power again, if the user has moved dashboard in outage.The user keeps movement of valve usually, and this valve operates in active process, in order to again proofread and correct described position transducer.For this reason, even on single valve, usually need comprehensive plant shut down.
Sensing absolute or the incremental encoder location information needs electric energy.In addition, when using incremental encoder, need extra electric energy that position information is kept in the storage.Absolute encoder does not need to preserve position information, because described information can be determined easily by absolute encoder.Utilize the valve acutator of incremental encoder when power failure occurring, to need reserve battery retention position information.For absolute and incremental encoder, during mains power failure, must come display position information by standby power supply.
There is a need in the art for the up-to-date position information of electronical display during the manually-operable of valve acutator, and don't need reserve battery.Related domain need to be to other electronic unit power supply of valve acutator.In addition, there is a need in the art for the power supply of hydraulic pressure and pneumatic valve actuator, and don't need to be by external power source.
