The status quo and development trend of China's gate valve market

Gate valves have the longest history of use, and are still used in various countries around the world, especially below DN300mm, which still dominate in various types of valves. The characteristic is that the pressure difference between the front and rear of the valve plate forces the valve plate to press on the valve seat on the right side of the outlet, with good sealing performance, and when the valve plate is fully opened, the pressure loss is small because the valve plate does not remain in the flow path. Used to cut off the medium in the pipeline.

The formation and harm of carbon deposits in air compressor

The reasons for the formation of carbon deposits in air compressors are more complicated. In terms of air compressor oil lubrication, the main reason is that the oil used in the internal lubrication system of the air compressor is often in the form of mist and high temperature, high pressure, high oxygen partial pressure air and metal The contact of the catalyst causes the air compressor oil to rapidly oxidize and deteriorate.
