The utility model provides a valve control device. The valve control device comprises a maintenance module and an electric control module. The maintenance module comprises a gearbox, a transmission mechanism and a motor, wherein the gearbox controls speed changes, the transmission mechanism is connected with the gearbox, and the motor supplies the gearbox and the transmission mechanism with power. The electric control module comprises a control clamp piece, a power source and a circuit, wherein the power source supplies power for the control clamp piece, and the circuit connects the electric control module with the outside. The valve control device is characterized in that the maintenance module and the electric control module are packaged in a split structure. Therefore, components of the electric control module are protected from affections from the severe environment of the maintenance module, and stability of the valve control device is improved.
Description
Technical field
The utility model relates to the control gear of valve, relates in particular to a kind of valve control device that engineering module is separated with electronic control module.
Background technique
Valve, as element conventional in each industrial field, no matter be simple, or complicated system all be unable to do without valve, and the control accuracy of valve has directly determined the precision and stability of system.And the operation of valve is divided into manual and telecontrol on the spot, telecontrol has again dividing of electronic control and pneumatic control.Along with the development of industrial level, automatically controlledly become a kind of very common control mode.
If the thermal power plant valve in China is exactly indispensable element, and control these valves well, directly have influence on the safety of generating efficiency and whole system, the valve control device therefore choosing seems most important.
But in prior art, valve is generally all arranged on that environment is severe, vibrations are large, temperature is high, corrode strong place; And the electric actuator of electro motion control valve be all be generally arranged to integrated, particularly: electric actuator is generally made up of engineering part (gear-box, driving mechanism, motor etc.) and automatically controlled part (power supply, control fastener, circuit etc.), most of actuators are integrated, be convenient to installation, transport, adjusting etc., but vibrations are large, temperature is high, corrode the environment such as strong severe under, easily cause the bad or Damage by Short Circuit of Control card in integrated electric final controlling element shake, thereby cause the valve cannot telecontrol.
Model utility content
Hold flimsy problem in order to solve in prior art electric actuator in valve control device, the utility model provides a kind of valve control device that can adapt to various rugged environment.
A kind of valve control device that the utility model provides comprises:
Engineering module, described engineering module comprises the gear-box that control rate changes, the transfer mechanism being connected with described gear-box provides the motor of power to described gear-box and described transfer mechanism;
Electronic control module, described electronic control module comprise control fastener, to described control fastener the power supply of energy is provided, by described electronic control module and the circuit that is connected of outside; It is characterized in that,
Described engineering module and electronic control module are packaged into split type structure.
Further, described engineering module is connected by cable with electronic control module.
Further, described engineering module and described electronic control module are directly also provided with control module.
Further, described control fastener is provided with the port being connected with outside Field bus.
Further, the setting of described control fastener and the radio communication unit that can exchange with outside signal.
By engineering module and electronic control module are packaged into split type structure, just electronic control module can be arranged on to environment compared with engineering module and valve position far away, vibrations in the work of engineering module or engineering module, valve are in compared with rugged environment like this, and the assembly in electronic control module can not be affected; Improve the stability of valve control device.And, control fastener be provided with the port that is connected with outside Field bus and with the radio communication unit that can exchange with outside signal; So just can realize Field Bus Control Technology and wireless control technology, make valve control system more intelligent.
