氣動圓頂閥閥芯表面經過超聲波振打處理，硬度及抗疲勞強度顯著提高，可以應對惡劣工況，橡膠密封圈采用進口特種材料制成，耐高溫性、耐腐蝕性、抗老化及抗磨損性能優越滿足各種環境安裝The surface of the (gas filled) imported pneumatic dome valve core has been treated by military level ultrasonic vibration, and its hardness and fatigue strength have been significantly improved to perfectly cope with severe working conditions. The rubber seal ring is made of imported special materials, and its high temperature resistance, corrosion resistance, aging resistance and wear resistance can be superior to meet the installation requirements in various environments
進口氣動圓頂閥性能參數 Performance description
氣動圓頂閥閥芯是一個半球體，氣動執行器通過擺臂驅動半球體轉動。在開閉過程中，半球體與橡膠密封圈保持有約0.2mm一0.4mm的間隙，因此避免了它們之間的接觸磨損。圓頂閥在完全關閉狀態時，橡膠密封圈自動充氣，膨脹后就緊緊裹持住半球體，從而形成一條可靠的密封環帶，阻止物料的流動 retz品牌 The (inflatable) inlet pneumatic dome valve core is a hemisphere, and the pneumatic actuator drives the hemisphere to rotate through the swing arm. During the opening and closing process, the clearance between the hemisphere and the rubber seal ring is about 0.2mm-0.4mm, so the contact wear between them is avoided. When the dome valve is fully closed, the rubber seal ring automatically inflates, and after expansion, it tightly wraps the hemisphere, forming a reliable seal ring to prevent the flow of materials.
公稱壓力∶1.0MPa ，密封試驗∶1.1MPa， 強度試驗∶1.5MPa
介質溫度∶≤250℃
氣缸的工作壓力為0.4MPa一0.6MPa，密封圈的充氣壓力為0.4MPa一0.6MPa且高于輸送壓力0.15MPa，使用潔凈、干燥、無油壓縮空氣 The working pressure of the cylinder is 0.4MPa - 0.6MPa, and the inflation pressure of the seal ring is 0.4MPa - 0.6MPa, which is 0.15 MPa higher than the delivery pressure. Clean, dry, oil-free compressed air is used
1.在關閉指令下，氣動執行器通過擺臂驅動半球體轉動90°，當擺臂上的調整螺栓壓住二位三通機械滑閥的頂桿時，氣源對橡膠密封圈充氣。壓力表顯示出密封圈內的壓力 Under the closing command, the pneumatic actuator drives the hemisphere to rotate by 90 ° through the swing arm. When the adjusting bolt on the swing arm presses the ejector rod of the two position three-way mechanical slide valve, the air source inflates the rubber seal ring. The pressure gauge shows the pressure in the seal ring
2.在打開指令下，氣動執行器通過擺臂反向驅動半球體轉動90°，在擺臂上的調整螺栓脫離二位三通機械滑閥的頂桿瞬間，密封圈中的氣從二位三通機械滑閥的排氣孔排出，密封圈回縮，保證了半球體轉動過程中與橡膠密封圈之間無接觸運動 Under the opening command, the pneumatic actuator reversely drives the hemisphere to rotate by 90 ° through the swing arm. At the moment when the adjusting bolt on the swing arm breaks away from the ejector pin of the two position three-way mechanical slide valve, the air in the seal ring is discharged from the exhaust hole of the two position three-way mechanical slide valve, and the seal ring retracts, ensuring no contact movement between the half sphere and the rubber seal ring during rotation
適用介質氣體、液體、半流體及固體粉末 Suitable for medium gas, liquid, semi liquid and solid powder
進口氣動圓頂閥結構特點/Structural Features
圓頂閥由于其獨特的閉合和密封步驟，避免了閥門的動靜件的摩擦，且閥門開啟時，料口全流通無阻擋，關閉時密封嚴實，橡膠密封圈采用特種橡膠制造具有耐高溫、耐腐蝕、耐老化等優點 Due to its unique closing and sealing steps, the dome valve avoids the friction between the moving and static parts of the valve. When the valve is opened, the full flow of the material port is unblocked, and when it is closed, the seal is tight. The rubber seal ring is made of special rubber, which has the advantages of high temperature resistance, corrosion resistance, aging resistance, etc
