四、Warranty 氣動三通煙氣閥技術協議書 保修

本實用新型公開了一種有機廢氣凈化處理回收設備氣動三通閥，它涉及有機廢氣凈化領域，它包含氣缸、氣缸接座、上端蓋、上閥體法蘭、進氣接口、上閥體、拉桿、半對開環、密封圈、進出氣接口、中閥體、排氣孔、中閥體連接法蘭、閥板和下閥體；它結構設計合理，造型新穎*，操作簡單，使用方便，法蘭和閥座之間采用整體成型的方式降低了設備的加工難度、加工量和焊接難度、焊接量，也可降低閥座在閥體上焊接后產生變形，氣缸拉桿下部半圓形連接頭臥在連接法蘭上的半圓形凹槽內，由半對開環與連接法蘭固定，使拉桿的半圓頭鑲嵌在閥板上，從而閥板可以小幅度上下旋轉一定角度，使閥板能更有效、更穩妥的壓在密封圈上。由于這種閥門的工作環境處于經常處于高溫煙氣中，因此業內也常稱之為高溫煙氣三通閥。目前，現有的高溫三通閥包括閥體、閥桿、螺桿、螺母；安裝后，閥桿的下端伸入閥體內，閥桿的上端和螺桿的下端通過銷軸連接起來，螺桿的中部安裝有螺母，螺母安裝于軸承座內且螺母的上端部分伸出軸承座；螺母旋轉時，帶動螺桿做直線運動，進而通過閥桿帶動閥體的閥瓣完成閥門的操作。但是現有的這種閥門，閥體受到高溫煙氣的熱傳導作用，而由于螺桿的一部分還是伸入到閥體內，因此閥體將熱量傳遞給螺桿，進而傳遞給螺母，這造成螺桿、螺母之間潤滑脂的不斷揮發，不斷增大螺桿、螺母之間的運動阻力，影響閥門的正常工作運行。 Regarding the guarantee issue please see the Commercial Contract.關于保修條款見商務合同。
①齒輪齒條雙活塞對稱結構設計，動作快速平穩，精度高，輸出功率大，通過簡單的改變活塞裝配位置可得到反方向旋轉。
②擠壓的鋁合金缸體，經精密加工的內孔和外部表面進行硬質陽極氧化處理（特殊情況下陽極氧化+特氟隆涂層），使用壽命更長，摩擦系數低。
③一體式設計，所有的雙作用和單作用執行器型號，都具有相同的缸體和端蓋，很方便通過加裝彈簧或拆除彈簧來改變作用方式。
④組合式預符荷安全彈簧組，不論在裝配過程或使用現場中，都能方便而安全的安裝或增減彈簧數量。
⑤外部側面兩個單獨調節螺釘對于已安裝在閥門上的執行器更是方便，調節閥開和閥關位置，如需全行程調節時則另外在兩個端蓋處配置較長調節螺釘。
⑥多功能位置指示器，現場可視化指示，符合VID/VIE3845、NAMUR標準槽，能安裝并輸出所有附件，如限位開關盒、電氣定位器、位置傳感器（倍加福、圖爾克）。
⑦氣源接口符合NRMAR標準，可直接安裝NUMAR標準電磁閥。
⑧齒條背面的復合材料軸瓦和活塞導向環以及輸出軸的軸承等為防止金屬對金屬的摩擦，并且增加潤滑,使其低摩擦、長壽命。
⑨所有的緊固件均采用不銹鋼材料，抗腐蝕。
⑩連接部分符合全新標準規范ISO5211，DIN3337（F03-F25）使產安裝具有互換性、通用性。
