Do many customers have it, how to install the flange butterfly valve? How to install the wafer butterfly valve? Are the flanges used in butterfly valves common? For such questions, let's talk about the installation method of the butterfly valve. 1. Before installing the upper pipe, check whether the parts of the stainless steel butterfly valve are damaged, whether there are impurities in the pipe, and whether there is any abnormality in the solenoid valve, and check the valve model. Second, the butterfly valve and the cylinder should be debugged to close. 3. Install the cylinder horizontally or vertically on the butterfly valve, check whether the screw holes are on the right, if not, fix the screw after the cylinder is debugged.
4. After the butterfly valve is installed on the cylinder, it is debugged. Generally, the pressure value is PN4~PN6. During the adjustment process, the solenoid valve switch can be connected. Check the switch status of the stainless steel butterfly valve during operation.
5. After the butterfly valve is put into storage, remember not to put it in harsh environments such as humidity, and not to place it in the open air. 6. Before the butterfly valve is installed on the upper pipe, make sure that there is no debris in the pipe. 7. Wafer or flanged butterfly valves should be equipped with standard flanges, or directly use standard butterfly valve flanges, and do not support the installation of flat welding flanges.
8. After installing the flange in the pipeline, pay attention to check the welding points. After the butterfly valve is installed, it is not allowed to weld again. The high temperature of electric welding may damage the sealing rubber ring of the butterfly valve (hard-sealed butterfly valve does not have this problem). When the butterfly valve is installed on the pipeline, the corner mounting bolts and nuts should be tightened in sequence.
