Hand in hand teaching you how to install and use regulating valves
The installation of the regulating valve is a key issue that should be paid attention to, and the quality of installation directly affects the use of the regulating valve. What are the following issues to pay attention to during the installation process.
Before installing the regulating valve, it is necessary to carefully remove the accumulated dust during storage and maintain cleanliness during installation. Because dust can damage the valve seat and internal components. To maintain cleanliness, a cover plate is usually installed at the end of the flange that has not been welded on the same day.
When installing the regulating valve, the arrow on the valve body should be aligned with the flow direction of the medium.
3 regulating valves are precision components, and if they are subjected to the force of pipeline deformation, it will affect their normal operation. Therefore, the flange and pipeline installation should be vertical and accurately positioned to avoid deformation of the pipeline, and the pipeline should be appropriately supported to prevent bending and deformation under the weight of the valve.
