[0002] A valve is a control component in a fluid conveying system. It has functions such as shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion or overflow pressure relief. When factories use valves to control material conveying, valve leakage or damage often occurs. In this case, if the valve leakage is small or the damage is small, a simple sealing treatment is often performed to ensure the progress of material conveying. However, during continued use, the valve leaks or the degree of damage gradually increases. Simple sealing treatment still causes material leakage. If the valve leaks or is severely damaged, it is necessary to stop the conveying work and carry out repairs and replacements, which greatly reduces work efficiency. Summary of the invention
