Description

Technical Field

[0001] The utility model mainly relates to the technical field of electric regulating valves, in particular to a corrosion-resistant 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), quick and easy to install (no need for complicated pneumatic pipelines and air pump workstations), and valves are divided into three types according to the power used by their actuators, their functions and characteristics: linear characteristics, equal percentage characteristics and parabolic characteristics.

[0003] For example, Chinese patent publication number CN216009620U discloses a corrosion-resistant electric regulating valve, including an electric regulating valve body, a support seat is fixedly installed on the upper end of the electric regulating valve body, support plates are fixedly installed on the left and right sides of the upper end of the support seat, an electric control box is fixedly installed on the upper end of the support plate, a valve stem is rotatably installed on the lower end of the electric control box, the valve stem extends into the interior of the electric regulating valve body, a spherical valve is fixedly installed on the lower end of the valve stem, a liquid inlet channel is fixedly arranged on the left side of the upper end of the electric regulating valve body, a cooling pipe is fixedly connected to the lower end of the liquid inlet channel, and a liquid outlet channel is fixedly arranged on the right end of the cooling pipe.

[0004] The corrosion-resistant electric regulating valve in the above application is installed with a cooling pipe, which is a serpentine structure. When the temperature of the electric regulating valve is too high, coolant is injected from the inside of the cooling pipe of the liquid inlet channel box. The cooling pipe with a serpentine structure can make the coolant cool and dissipate the heat of the electric regulating valve more evenly, thereby improving the cooling effect. The existing electric regulating valve will accumulate a lot of debris after long-term use, causing the regulating valve to be blocked, especially at the valve. The debris will also erode the valve, causing valve corrosion, affecting the sealing performance, and affecting the service life of the device. Utility Model Content
