A47H安全閥|A47H帶扳手彈簧微啟式安全閥|彈簧安全閥
本實用新型涉及一種防爆波閥門,包括閥體、進水法蘭、出水法蘭、閥座、閥板、支撐桿、消波室;閥座設(shè)置在閥體內(nèi)部靠近進水法蘭一端,位于閥座的右側(cè)設(shè)置有支撐架;支撐桿的右端與支撐架螺紋連接,支撐桿的左端安裝有閥板;支撐架與閥板之間安裝有彈簧,彈簧套在支撐桿上;消波室設(shè)置在閥座與出水法蘭之間;彈簧外套有橡膠套;閥體內(nèi)部靠近進水法蘭一端設(shè)置有消波槽Ⅰ。在閥體內(nèi)部靠近進水法蘭一端設(shè)置有消波槽Ⅰ,使得沖擊波在到達閥板前已被消波處理,避免閥板受到過大的沖擊力;消波槽Ⅰ的深度由左向右依次遞增這一特征增大了消波效果。
