Q:Measure the temperature with a thermocouple, and then how to make the valve open when the temperature reaches a certain value. When the temperature is lowered, will the valve be closed?Or tell my brother what is the knowledge, I can see it myself. Good. How much extra?!

A relay or PID controller can achieve this operation, only need to set out, the valve can use electromagnetic valve, which belongs to a rapid opening and closing valves, only need to control the electric power to the valve can automatically open or closed, but the temperature change is large, if you want to keep the temperature constant. The best selection of regulating valve, constant temperature control valve will be before or after the valve, the main electrical control knowledge, do not know what I said is clear, remember the points, thank you!

Q:What are the advantages and disadvantages of this method? Are there any other ways to adjust the flow rate?

With the advantages of the pump outlet valve adjustment, 1, you can control the pump outlet pressure, 2, you can control the motor current is not more than the process conditions, 3, control motor power, to ensure the normal operation of the pump.

Q:What valve is the FCV?

FCV is the control valve, you can adjust the valve opening according to the required flow.1, also known as the valve control valve, in the field of industrial automation and process control by adjusting the control unit outputs the control signal, the final control element with the power to change the media flow, pressure, temperature, level and other parameters. Generally composed of actuators and valves.2, according to the characteristics of the trip, the control valve can be divided into straight stroke and angular stroke. According to the power used by the executing agency, according to its function and characteristics are divided into linear characteristics, such as percentage characteristics and parabolic characteristics of the three. Control valve applies to air, water, steam, a variety of corrosive media, mud, oil and other media.

Q:Is the filter also valve?

Classification, filter does not belong to the valve filter is indispensable to a device on the pipe conveying medium, usually installed in the valve, pressure relief valve, inlet water valves or other equipment end, used to remove impurities in the medium, to protect the normal use of valves and equipment. When the fluid enters the filter cartridge has a certain size, the impurities are blocked, and clean filtrate from the filter outlet, when cleaning, as long as the removable cartridge is removed, you can reload after treatment, therefore, maintenance is extremely easy to use.
