The role of electronically controlled regulators in industrial production cannot be ignored. After years of development, the regulators produced by valve manufacturers have also been greatly improved. One of the most commonly used control valves is the electric control valve. Compared with the traditional pneumatic control valve, the ultra-high pressure solenoid valve has the advantages of high reliability, stable function, light weight and easy installation.
The company traditionally uses pneumatic control valves. The installation is not only the valve itself, but also the valve positioner for in-situ use. This not only increases the cost, but the increase in intermediate links reduces the reliability. In addition to saving the construction cost of the gas source station, the electronically controlled adjustment gearbox solenoid valve can also save the maintenance cost of the valve positioner, thereby reducing intermediate links and reducing maintenance workload.
Of course, the electric control valve itself has some shortcomings. When the internal heat generated during the operation of the motor causes thermal protection, the control valve stops working. In addition, compared with the pneumatic control valve, the internal mechanism of the electric control valve is more and more complicated, and it is more prone to failure in frequent use. Therefore, when selecting the control valve, the most suitable one should be selected according to the actual situation of the process site.
In the modern production environment, the role of electric control valve is very important, it is an important execution unit in industrial automatic control. Compared with conventional pneumatic control valves, electric control valves have the advantages of energy saving, environmental protection, convenient installation, safety and reliability.
The operating environment of the power regulator is also required. During installation, the installation layout should be carried out in accordance with the operating instructions of the valve model to meet its design requirements. In actual use, many problems are often not caused by the quality of the camshaft solenoid valve electric regulating valve itself, but caused by improper installation and use, such as the installation environment, improper installation position and direction, or dirty pipelines. The electronic control device is a field instrument, and the ambient temperature and humidity must be maintained at normal temperature. If it is installed outdoors, it must take waterproof and cooling measures, while avoiding seismic sources and electromagnetic interference.
Before installing the electric control valve, the inside must be cleaned to remove dirt and welding slag. In order to ensure that no impurities are left in the valve after installation, the valve should be cleaned again to prevent the circulating medium from being affected by impurities during subsequent use. In order to continue production when the electric control valve fails or is repaired during use, a bypass pipe must be installed on the control valve.
