During the installation of the automatic butterfly valve, the preliminary preparation work is crucial. First of all, it is necessary to carefully check the model and specifications of the selected automatic butterfly valve to ensure that it is perfectly matched with the pipeline system. In addition, be sure to conduct a comprehensive inspection of the appearance of the valve to confirm whether the key components such as the valve body, valve plate and valve stem are damaged, deformed or rusted. At the same time, prepare the tools and materials required for installation, including wrenches, screwdrivers, sealing gaskets, bolts and nuts. Cleaning the installation site to ensure that the environment is clean and there is no debris interfering with the installation process is also an important step to ensure smooth installation.
In the pipeline connection link, the pipeline needs to be aligned with the flange end of the automatic butterfly valve to ensure that the two flange surfaces are parallel and the spacing is uniform. At this time, appropriate sealing gaskets should be placed between the flanges, and the material of the gasket should be selected according to the characteristics of the transmitted medium to ensure a good sealing effect. After the bolts are evenly passed through the flange holes, the nuts are gently pre-tightened manually to make the two flanges fit initially. Next, use a wrench to gradually tighten the nuts in diagonal order to avoid flange deformation or sealing gasket damage due to uneven force. During the tightening process, the tightening torque must be strictly controlled to ensure that the bolt connection is firm and the sealing performance is good.
The installation and commissioning of the actuator of the automatic butterfly valve is a refined process. According to the type of actuator and its installation requirements, it needs to be correctly connected to the valve body. For electric actuators, ensure that the connection between the motor and the valve stem is firm, and check the flexibility of the transmission parts to ensure that there is no jamming. When connecting the power cord and the control signal line, be sure to follow the electrical wiring diagram to ensure the accuracy of the wiring. During the commissioning phase, the actuator should be fully functional tested, including manual and electric operation, as well as stroke setting. Check the flexibility of the actuator's movement manually to ensure that the valve plate can open and close normally. During electric operation, observe whether the movement speed and position of the valve plate meet the preset requirements. According to actual needs, accurately set the stroke of the actuator to ensure that the valve can accurately reach the fully open and fully closed positions.
System joint debugging and functional testing are important links after the installation is completed. At this stage, the automatic butterfly valve is connected to the entire control system, and the system joint debugging is carried out to check whether the communication between the valve and the control system is normal and whether the control signal can be accurately transmitted to the actuator. When conducting functional tests, simulate actual working conditions, open, close, and adjust the valve flow, and observe the valve's response speed, motion accuracy, and stability to ensure that it meets the system's control requirements. If any abnormalities are found during the test, such as leakage, obstruction, or inaccurate motion, they must be promptly checked and handled.
