характеристики герметизации клапана в низкотемпературных условиях

герметичностьindustrial valveTypes of Valve Sealing Performance To address this issue, low-temperature valve designs typically avoid using traditional non-metallic sealing materials, especially in environments where temperatures fall below -70°C. Non-metallic materials can be combined with metals through special processes to form composite structures to improve low-temperature sealing performance. However, some non-metallic materials still perform well at low temperatures. For example, polyethylene...

концентрические клапан-бабочка: простая конструкция

The concentric butterfly valve is a straightforward and widely used control valve, primarily employed in low-pressure piping systems for the control of medium flow and shut-off. Its main characteristic is the use of a disc-shaped valve disc (also known as the butterfly plate) as the closing element, which rotates around the valve shaft to open and close the valve. This type of butterfly valve is suitable for a variety of fluids, including air, water, steam, various corrosive media, sludge, oils,...
