| Q647氣動固定式球閥 一、氣動固定式球閥產品概述 挺揚公司生產的"挺揚"牌Q647氣動固定式球閥是新一代高性能氣動球閥，適用于長輸管線和一般工業管線，其強度、安全性、耐惡劣環境性等在設計時進行了特殊考慮，氣動固定式球閥適用于各種腐蝕性和非腐蝕性介質。Q647氣動球閥它與浮動球閥相比，工作時，閥前流體壓力在球體上產生的作用力全部傳遞給軸承，不會使球體向閥座移動，因而閥座變形小，密封性能穩定、使用壽命長，適用于高壓、大口徑場合。的彈簧預閥座組件，具有自緊特性，實現上游密封。每閥有兩個閥座，每個方向都能密封因而安裝沒有流向限制，是雙向。本閥有二塊式和三塊式兩種閥體結構，中法蘭用螺栓連接，密封采用增強聚四氟乙烯鑲入不銹鋼圈內，鋼圈后部設有彈簧保證閥座緊貼球體，保持密封。上下閥桿均設有PTFE軸承，減少磨擦，操作省力，小軸底部沒有調整片，保證球與密封圈的接處位置。氣動硬密封固定球閥采用全通徑的結構使閥門流量孔么與管線內徑*，以便管線清掃。與電氣閥門定位器配套，輸入4～20mADC信號及0.4～0.7MPa氣源即可控制運轉，實現對壓力、流量、溫度、液位等參數的調節。
二、氣動固定式球閥產品特點 （1）氣動固定式球閥采用固定球設計，相對運動部位均采用磨擦系數極小自潤滑材料，因而操作扭矩小，此外密封潤滑脂的長期密封，使得操作更加靈活。 （2）氣動固定式球閥采用全通徑或縮徑設計，流通阻力小。 （3）氣動固定式球閥閥采用固定球設計，并增加了預緊力彈簧，使得球閥具有自動泄壓功能。 （4）每個球閥都有兩個可動密封座，兩個方向都能密封，因而安裝時不須考慮介質的流向。 （5）具有防火防靜電結構，在閥桿與閥體及閥桿與球體之間設置導電彈簧，避免靜電打火點燃易燃介質。確保系統安全。 （6）耐火結構雙重保護，當萬一發生火災而使密封圈燒損時，球閥的各個密封部位均能形成金屬對金屬的硬密封結構。 三、氣動固定式球閥主要技術參數及性能
