1、安裝時,低溫閥門與管道配置不合理而產(chǎn)生預應力;或管道冷補償能力差,低溫下閥位改變;或閥門缺少支架,在低溫產(chǎn)生變形;或閥門固定不當,保冷箱在低溫下變形而影響閥桿與閥體的同心度。
2、在設計上,由于閥桿與閥套的材質(zhì)不同,線膨脹系數(shù)不同。一般閥桿用不銹鋼,線膨脹系數(shù)為1.73×10-6℃-1;閥套為黃銅,線膨脹系數(shù)為19.9×10-6℃-1,即黃銅的收縮比不銹鋼大,低溫下可能將絲扣咬住。特別是當采用暗桿結(jié)構(gòu)及細牙螺紋時,絲扣的溫度變化范圍大,螺紋間隙小,更容易產(chǎn)生咬住的現(xiàn)象。
3、在運轉(zhuǎn)中,由于低溫閥門處加溫不徹底,或閥門填料處進水,在低溫下造成凍結(jié),或在常溫下將閥門關(guān)閉過緊,使絲扣咬壞等。
