The function of the packing is to prevent the medium inside the valve body from leaking along the valve stem.
3) The main function of شیر بلند کننده گلوب in chemical pipelines is to cut off or connect fluid. شیر بلند کننده گلوب's regulating flow is better than gate valves, but شیر بلند کننده گلوب cannot be used to regulate pressure and flow for a long time. Otherwise, شیر بلند کننده گلوب sealing surface It may be eroded by the medium and damage the sealing performance.
4) شیر بلند کننده گلوب can be used in pipelines such as water, steam, and compressed air, but it is not suitable for medium pipelines with high viscosity, easy coking, and easy precipitation, so as not to damage the sealing surface.
