Introduction to dome valve:
Dome valve DN150 P30660D-00 is specially used in pneumatic conveying system, and can also be provided to customers as an independent product. Its application fields in industry include power, food, medicine, chemical, plastic, mining, steel and other industries. Commonly used conveying materials are: abrasives, particles, powders, ash, chemicals, ores, coal, fragile products, etc.
Dome valve DN150 P30660D-00 main configuration: linear cylinder DN150 P22457E-00, limit switch A1011 , V -type dust ring ￠67 DN150 M1346 , coupling DN 150 CP4965C-00, shaft seat DN150 CP46780E-00, drive shaft DN150 CP4675D-00, spring cylindrical pin DN150 GB879-86, dome DN150 CP4677B-00, top joint DN150 CP29756B-00, collar DN150 CP29615D-00, support ring DN150 CP29614D-00, plug-in seal DN150 P4665B-01, high temperature plug-in seal DN150 P17459C-00, combined bearing DN150 P8010D-00, spacer ring DN150 CP5406D-00, VARI seal ring ￠40 DN150 M1365 O-type seal ring DN150 M5205, quick exhaust valve DN150 3/8” A1790, seal assembly DN150 M3229, top plate DN150 CP29668D-00, etc.
Dome valve principle:
①. The exhaust dome valve can cut off the flowing material flow or static material column entering the pressure tank, and then close to achieve sealing. This ensures that the filling rate in the tank is 100% , and there is no need to rely on the level meter of the sending tank, so the control principle is simple and reliable.
② When handling abrasive materials, the expandable pressure seal ring embedded in the dome valve seat ensures the working pressure difference before and after the valve. The elastic expandable seal ring can be sunken into the material particles, avoiding the sliding of the material particles due to the pressure difference and the wear of the valve seat and seal ring.
③ When slurry, bulk powder, particles, lumps or dust filled with gas will wear the seal ring, resulting in ineffective sealing. The expandable seal ring provides continuous wear compensation. The pressure difference will accelerate the wear of the traditional hard seal valve, and the expandable seal ring provides continuous wear compensation.
④. Thermal expansion will hinder the continuous operation of the dome valve; the expandable sealing ring can provide wear compensation in the temperature range of -40 ℃ to 320 ℃; the specially constructed dome valve can perform work above this temperature range.
⑤ The displacement of the rotating dome valve core in the valve body enables the dense material column to rotate, so that the dome valve completely filled with material can pass through the filled material to close and seal.
Characteristics of dome valve:
① Unhindered material flow throughout the chamber
②. Simple and reliable design
③. Flexible opening and closing, can shut down dynamic and static material columns
④. Complete specifications and sizes: DN50-DN300
⑤. A strong pressure seal can be formed when closed
⑥, can withstand temperatures from -20℃ to 480℃
⑦. Long service life and low maintenance
⑧. The material conveying system of the power plant operates normally, and the service life of the plug-in seal ring is more than one year
