Selection of electric butterfly valve for butterfly valve in various equipment
In steel plants, power plants, oil plants, cement plants and other industries, there are various types of pipelines and equipment, and they will choose to add some components for maintenance according to the request. These industries have a high demand for pipelines, so most of the center uses butterfly valves and electric butterfly valves. But electric butterfly valve
There are many varieties, so there is a request for its selection.
1. The outer surface of the shell and butterfly valve shall be treated by: paint baking, galvanizing, zinc aluminum treatment and other methods to prevent the vibration isolator from rusting in a short time, which will affect the service life of the electric butterfly valve. It is better not to use the products treated by painting;
2. The longitude between the operating frequency of the equipment and the natural frequency of the electric butterfly valve of the butterfly valve shall be greater than
3. How to ensure that the vibration isolation efficiency is above 85% under this condition;
4. The stiffness and vertical rigidity of the butterfly valve shall be greater than or equal to 1, and the ratio between the requested butterfly valve diameter and the height of the butterfly valve after the rated negative pressure shall be greater than 0.7, so as to ensure the stability of the degree direction of the electric butterfly valve of the butterfly valve;
5. Suitable butterfly valve electric butterfly valve shall be selected as the guide line of the convenient device.
As long as the right electric butterfly valve is selected, it can play its role more effectively. If the wrong model is selected, it may not only fail to maintain, but may backfire, causing unnecessary damage to the pipeline or equipment.
