7、 Precautions for installation and use of electric telescopic butterfly valve

1. The telescopic butterfly valve must be placed flat before installation and must not be bumped randomly.
2. The structural length of the telescopic butterfly valve is the minimum length when it leaves the factory, and during installation, it is pulled to the installation length (i.e. the design length).
3. When the length between pipelines exceeds the installation length of the expansion valve, please adjust the pipeline spacing and do not forcefully stretch the expansion valve to avoid damaging it.
4. The telescopic butterfly valve can be installed at any time. When used for temperature compensation, after the pipeline installation is completed, brackets need to be added at both ends along the axis direction of the pipeline to prevent the telescopic valve from pulling out. The support force of the bracket is calculated according to the following formula, and it is strictly prohibited to remove the bracket during operation.
5. When the telescopic butterfly valve does not perform temperature compensation and is only used for installation, replacement, and maintenance of the valve for convenience, a butterfly bolt can be used to limit and symmetrically clamp the telescopic butterfly valve to prevent the telescopic pipe from pulling out, damaging the telescopic butterfly valve and pipeline equipment or buildings. The bolt diameter can be calculated according to the flange bolt diameter, its bolt strength, and the test pressure and pipeline tension it can withstand, using the above formula. During operation, it is strictly prohibited to remove the limit bolt (bolts are provided separately)
6. It is strictly prohibited to dismantle and dismantle the telescopic butterfly valve at the pipeline construction site.
7. This scalabilityelectric butterfly valveThe processing is fine and the fit is tight. Please do not repeatedly elongate or shorten the telescopic butterfly valve on site. When installing the pipeline, it is required that the two ends of the expansion valve pipeline must be concentric, and the two flange surfaces on the pipeline must be parallel.
8. The flange fixing bolts should be symmetrically tightened, and do not forcefully tighten the flange fixing bolts on one side.
9. The expansion pipe is installed behind the valve.
10. The expansion part of the expansion valve shall not be installed at the corner or end of the pipeline.
