The introduction of sanitary butterfly valve parameters and working principle adopts standards: structural length: GB/T12221-1989 pressure test: GB/T13927-1992; JB/T9092-1999 design standard: GB/T2238-1989 flange connection size: GB/T9113. 1-2000; GB/T9115.1-2000; JB78 sanitary stainless steel quick-install butterfly valve Product details: sanitary stainless steel quick-install butterfly valve uses advanced standard electronic polishing technology to make the surface of the valve smoother and cleaner, and will not appear during time use The medium accumulation area can effectively avoid potential pollution. The valve is easy to assemble and disassemble, and the maintenance time is fast, which can be shortened to the greatest extent. This product is mainly used in the process control occasions of dairy products, food, pharmaceuticals, beer, cosmetics, clean steam, beverages, and biochemical industries. The main characteristics of the sanitary stainless steel quick-install butterfly valve are: 1. Novel structure, reasonable design, simple operation, light weight, fast and agile opening and closing. 2. The operating torque is small, the assembly and disassembly are convenient, and the use is dexterous. 3. It can be installed in any position, easy to maintain. 4. The sealing material has the advantages of aging resistance, corrosion resistance and long service life. ·The working principle of the quick-install butterfly valve The quick-install butterfly valve is a valve that uses a circular butterfly plate as the opening and closing part, and uses the valve stem to rotate the opening and closing and adjust the fluid passage. The butterfly plate of the butterfly valve is installed in the diameter direction of the pipeline. The butterfly valve body is in the cylindrical channel, and the disc-shaped butterfly plate can be rotated around the axis. The standard rotation angle is about 0°~90°. When the rotation is 90°, it will reach the fully open state. When the valve is fully opened, it has a small flow resistance. When the opening direction is 15° to 70°, fast flow control can be performed. Therefore, the butterfly valve should have a very wide range for large-diameter adjustment. The valve plate of this butterfly valve has a wipe movement function. When welding the butterfly valve, the medium with suspended fixed particles can be used. According to the strength of the seal, it can also be applied to powder and granular media.
