Butterfly valve electric actuator

With the development of marine ships, the highly automated remote Control Valve pressure system has become one of the necessary equipment in the ship, and its actuator  is the key component to drive the valve. In view of the requirements of the ballast water system of marine butterfly valve in oil tankers and chemical tankers, a special Hydraulic Actuator was designed, and the actuator's actuator execution, structural layout and key technology were described. Keywords:Structural layout of valve remote control Hydraulic Actuator CLC Number:TH122:TC751 Literature identification code:A Marine valve ballast water system plays a very important role in adjusting the longitudinal and transverse stability and safe centering height of the ship's hull, and the butterfly valve remote control system is a very important part of the ballast water system. The butterfly valve remote control system is mainly divided into two parts: hydraulic drive system and upper and lower computer control system, of which the hydraulic drive system mainly includes hydraulic pump station, solenoid valve box group, liquid shimmer circuit element, hydraulic actuator, butterfly valve, etc., and the hydraulic actuator directly drives the butterfly valve, which is the key component of the butterfly valve remote control system, which directly affects the stability, reliability and safety of the whole system. Although there are many domestic enterprises producing hydraulic actuators, there is still a large gap between the technical level and foreign countries, and the overall structure of the product is often sacrificed in order to ensure the safety of the product, so it is bulky compared with foreign products, with low execution efficiency and short service life. Therefore, it is necessary for domestic relevant enterprises and scientific research institutes to work together to improve the design and manufacturing level of actuators .
