• Working principle and structure composition of electric valve

    Introduction to the working principle of the electric actuator: The electric valve is usually connected by an electric actuator and a valve, which becomes an electric valve after installation and commissioning. The electric valve uses electric energy as power to connect the electric actuator drive valve to realize the valve switch and adjust the action.In order to achieve the pipeline medium switch or adjustment purposes. Electric Valve drive is generally with the motor, on or off the completion of the…

  • Three-way electric valve selection method?

    Electric three-type regulator valve selection basis: First, according to the pipeline parameters to choose the electric two-way regulator valve: diameter Specifications (that is, DN), interface mode 1, according to the field pipeline diameter size or flow requirements to determine the diameter (DN) size. 2, interface mode, General >DN50 to choose Flange Interface, ≤DN50 can be freely selected according to user needs. Second, according to the fluid parameters to choose the electric two-way regulator valve: material, temperature group 1, corrosive fluid:…

  • Fault and treatment method of electric regulator valve

         The working performance of the electric regulator valve will directly affect the working quality of the whole regulation system. Because the electric regulating valve is in direct contact with the tuned medium in the field, the working environment is very bad, so it is easy to produce all kinds of faults. In addition to troubleshooting these faults at any time during the production process, regular maintenance and regular repairs are required. Especially for the use of the environment…

  • Features of explosion-proof electric valve electric device

    Valve using tight seal or valve pressure, valve cover seal washer structure, trustworthy, safe and reliable. The valve adopts an intermediate double plate universal top structure, which automatically adjusts the fit between the valve and the seat sealing surface to ensure that the valve is sealed, while this structure is easy to maintain, saves cost and better valve interchangeability. Seat sealing surface spraying tungsten carbide, by the plasma formation of cobalt chromium alloy, sealing surface hardness is high, wear-resistant, wear-resistant,…

  • What are the requirements for valves when the Qoto electric actuator is installed

    The valves of the QOTO electric actuator will have a variety of assembly standards during the actual assembly process, but such electric actuators do not work alone, but they basically need to have a comprehensive device link with the valve or some other solenoid valve so that they can be used,And when the QOTO electric actuator is installed, there are a variety of mounting methods that can be divided into direct-attached mounting methods, or base-type mounting methods. Generally speaking, when…

  • Internet + agriculture, intelligent irrigation, the inevitable trend of the development trend of the times!

    In the Internet era, under the social form of intelligent commerce, agricultural enterprises need to take the wings of the Internet and carry out a profound intelligent transformation in order to get out of their own way in the torrent of the Times. How to make intelligent change?–Internet + agriculture, intelligent irrigation. Mobile phone remote irrigation, mobile phone in hand, irrigation do not worry. Now can also be through the pump room or mobile phone, the farmland remote real-time monitoring,…

  • Valve mobile phone control based on IoT control

    As mentioned above:part 1   5. Type of sensor used Several types of sensors are used to transfer data to the irrigation multi-controller unit. Each cell is dedicated to capturing and transferring specific data. The first unit is the Soil Moisture sensor (or SMS), which checks the dielectric constant of the soil surface to estimate the volume water content of the surface. The humidity level is proportional to the dielectric constant reading. An SMS controller can be “On demand” (with…
