First, an overview of intelligent electric valve ROTORK as the world's leading actuator manufacturer, its durable products and world-renowned, with a few decades under various environmental installation, use the experience, has developed a high design reliability. And the actuator is a leader in operational and safety applications. British Rotork (ROTORK) company in the 1990s introduced the intelligent electric actuators (IQ series), the world's first launch of the actuators - can make you do not open the electric box cover can be commissioned and interrogated, and Normal actuator has the following advantages: (1) Convenient remote setting function parameters. Before being put into use, as long as the use of special setting tool provided by the manufacturer, align the actuator can be remote setting parameters. Not only simplifies the set procedures, but also to improve the safe operation of the equipment, especially those requiring proof of the place is particularly important; (2) extensive online display. Using liquid crystal display technology, with built-in liquid crystal display panels, not only can accurately show the valve opening and closing state and a normal valve opening, etc., and at the time of the parameter setting or actuator failure, can also display important information; (3) Perfect self-diagnosis and protection. It is available online diagnosis of the servo motor overload, overheating and power of the state, etc., it can automatically recognize three-phase power phase, in case of emergency, the actuator may secure his position or run to a safe predetermined position; (4) Advanced control functions. Use of computer technology, the advanced control technology is designed to automatically follow it a standard feature. Actuator response speed and size is proportional to the deviation of the actual requirements, the so-called "speed control", greatly improving the quality of the implementation of response. Second, intelligent electric valve actuator performance dual seal, double protection IQ enclosure is rated protection class IP68- 3 meters underwater, 48 hours, NEMA4 / 4X / 6. It is fully waterproof and dust-proofing, and not "breathability." Rotork Double Seal system ensures protection of internal components, because they are waterproof terminal block internal cables and wiring terminal box isolation. Even during field wiring, remove terminal cover, protection is still maintained, and the terminal block individually sealed. Non-invasive sealed for life IQ site commissioning without removing the electrical box cover. All settings and adjustments are set using the supplied infrared to complete. After assembly in the controlled environment of our manufacturing facilities, the gas exchange has been excluded - all internal components are protected for life. Non-intrusive control means without passing through the control box through shaft. Simple, reliable, IQ simplifies the design and specifications, and performance has been expanded. Actuator torque measurement can be precisely measured reliably operate a valve of the force, which is to provide protection for valve and actuator base. IQ using its patented output torque measurement system, which is familiar from such a process similar to the pressure sensor measurement technology developed from. In industry after verification and testing of this technology applied to the valve actuator. In the case with the load, with the varistor sensor installed in the torque sensor, motor worm thrust reaction directly into electrical signal proportional to the output torque obtained accurate, repeatable torque measurement and independent of frequency, voltage and temperature variations. Valve position measurement Reliable process control depends on accurate positioning of the valve stroke end, and hydraulic control depends on accurate positioning of the valve stroke in the middle. Patented non-contact position measuring system is the most simple actuator control design. Only one moving part of the resolver output center sleeve rotation into electrical signals, then the limit is stored in a secure, permanent memory for comparison. Element to reduce sound mechanical and electrical systems and the reliability is improved. IQ as the foundation, structure and control of the chassis to improve the handwheel improve the reliability of the actuator. Latest quot;?. System on Chip "technology has been applied to the IQ control module due to significantly reduce the number of components, thereby reducing the interconnection wiring and printed circuit board complexity with a display function such as data and better system protection. enhancements to improve the performance and reliability of safety integrity IQ was originally developed to improve the integrity of state security valve actuators by re-design and innovation, Rotork can provide solutions, process engineer can determine the security in accordance with Integrity rating select actuator Given IEC615081, ISA-S84.01 and DIN19250, and other international standards become perfect asked to evaluate the safety technology system, Rotork will be happy to discuss your requirements are detailed:. http: //www.chuanhuvalve.com /ddtjf/ddtjf-zrzp.asp
