一、產品概述
偏心半球閥 PQ40H 屬于直通式半球閥，無縮徑，閥體通道與管線連接的管道成直管相通，截面積相等，阻力小于縮徑，全開、全閉只要轉動90度即可達到，方便長距離管線輸送控制。采用偏心結構原理，通過傳動機構達到閘緊、調節、關閉的目的。雙偏心結構球閥在開啟時球體藏于閥腔內，流通載面大，關閉時閥芯球面沿閥座漸進，具有剪切功能，有效地切除結垢障礙，實現可靠密封。
全通徑偏心半球閥用來控制含塵氣體、顆粒流體的煤粉噴吹等固體輸送的理想設備，廣泛應用于冶金、選礦、電力等生產工藝中高爐煤粉噴吹、制粉系統以及除塵系統中的各種管線控制。它采用直通式結構，流道暢通，不會出現積灰堵塞現象，密封副采用合金材質，經過特殊熱處理，閥門抗沖刷耐磨損，同時閥門偏心球面具有自動補償的性能，通過蝸輪上的調節螺栓，使密封副在一定程度磨損的情況下，仍可達到重新密封的效果。
偏心半球閥產品特點：
1．產品采用半球結構，臥裝方式，開啟后半球體位于通道上方，完全脫離通道，因此閥門流通能力大，不沉積雜質.
2．半球體采用三偏心結構，開啟時迅速脫離閥座，有效防止密封面的摩擦損傷，并減小了操作力矩，延長了閥門的壽命。
3．半球體高硬度密封面與金屬閥座配合具有剪切作用，能剪斷鐵絲及各種纖維織物，不纏繞，不沉積。是污水處理系統首選閥門。
