Description

[0001] The utility model relates to the technical field of electric valves, in particular to a modular electric regulating valve. Background Art

[0002] Electric control valves are important actuator instruments in industrial automation process control. With the increasing degree of automation in the industrial field, they are being used more and more in various industrial production fields. Compared with traditional pneumatic control valves, they have obvious advantages: electric control valves are energy-saving (only consume electricity when working), environmentally friendly (no carbon emissions), and quick and easy to install (no complicated pneumatic pipelines and air pump workstations are required). At present, a lot of debris will accumulate in the electric control valve after long-term use, which is easy to corrode the inside of the control valve, and the accumulated debris is extremely easy to clog the device. Most of the existing electric control valves are not convenient for cleaning the debris. At the same time, the electric control valve will be impacted by the water flow when switching, and most electric control valves cannot buffer the impact, which is inconvenient to use.

However, the regulating valve is additionally provided with a second motor in the pipeline through which the fluid flows, which not only affects the smoothness of the fluid when it flows, but also increases the impact effect of the fluid on the regulating valve, and makes the internal structure of the regulating valve more complicated, which in turn increases the probability of damage to the regulating valve. Moreover, the vulnerable structure of the regulating valve is mostly arranged in the pipeline of the electric regulating valve body, so that when the internal structure of the regulating valve is damaged, it cannot be conveniently maintained, which increases the difficulty of maintenance for workers.
