Work performance and installation: The utility model has the advantages of simple and compact structure, reasonable design, light material, reliable sealing, light and flexible operation, small volume, smooth passage, small flow resistance, light weight, easy installation, and easy disassembly. It can work normally under working pressure of 1.0MPa-2.5MPa and using temperature of -29-650°C. Knife-type gate valve has a shearing function, which can scrape off the sticky material on the sealing surface and remove debris automatically. The stainless steel gate plate can prevent the sealing leakage caused by corrosion.
