Electric valve positioner is designed according to the principle of force balance, and its working principle is based on the pneumatic valve positioner developed from the current signal control valve positioner. When a current signal from the electric regulator is input to the coil of the torque motor assembly, a magnetic field is generated in the air-gap of the torque motor, which interacts with the magnetic field generated by the permanent magnet to cause the armature to generate a leftward force, Lever (armature) around the fulcrum ⒂ rotation, the baffle close to the nozzle, the nozzle back pressure amplified by the amplifier, the film into the actuator chamber, the valve stem down, and drive the feedback lever around the fulcrum rotation, connected to the same axis The feedback cam rotates in the counterclockwise direction, the pay lever rotates around the fulcrum by the roller, and the feedback spring ⑾ is stretched. When the pulling force of the spring on the main lever and the torque motor act on the main lever are equal, Balanced state. At this moment, a certain signal current corresponds to the position of a certain person's valve. Spring is used to adjust the zero. The above mode of action is a positive role, to change the mode of action, as long as the cam flip, A to B and so on, you can. The so-called positive positioner, is the signal current increases, the output pressure also increases; the so-called reaction positioner, is the signal current increases, the output pressure is reduced. A positive acting actuator can act as a reactionary actuator as long as it is fitted with a reaction positioner. On the contrary, a reactionary actuator can act as a positive acting actuator as long as it is equipped with a reaction positioner.
Tech Grade Phosphate
Tech grade phosphate refers to a type of phosphate that is used in various technological applications. It is typically a high-purity form of phosphate that has been processed and refined to meet specific requirements for use in industries such as electronics, ceramics, and metallurgy.
Tech grade phosphate is often used as a raw material in the production of phosphoric acid, which is a key ingredient in the manufacturing of fertilizers, detergents, and other chemical products. It can also be used as a flux in the production of ceramics, helping to lower the melting point of materials and improve their flow during firing.
In the electronics industry, tech grade phosphate can be used in the production of semiconductors and other electronic components. It can help to improve the electrical conductivity and performance of these devices.
In metallurgy, tech grade phosphate can be used as a flux in the production of steel and other metals. It helps to remove impurities and improve the quality of the final product.
Overall, tech grade phosphate is an important material in various technological applications, providing key properties and functionalities that contribute to the performance and quality of the end products.
