</p><p> <span style="font-size:16px;">有些閥門還須有外部保護，這就是保溫和保冷。保溫層內有時還要加拌熱蒸汽管線。什么樣的閥門應該保溫或保冷，要根據(jù)生產要求而定。閥門起吊時，繩子不要系在手輪或閥桿上，以免損壞這些部件，應該系在法蘭上。對于閥門所連接的管路，一定要清掃干凈。可用壓縮空氣吹去氧化鐵屑、泥砂、焊渣和其他雜物。這些雜物，不但容易擦傷閥門的密封面，其中大顆粒雜物（如焊渣），還能堵死小閥門，使其失效。安裝螺口閥門時，應將密封填料（線麻加鋁油或聚四氟乙烯生料帶），包在管子螺紋上，不要弄到閥門里，以免閥內存積，影響介質流通。安裝法蘭閥門時，要注意對稱均勻地把緊螺栓。閥門法蘭與管子法蘭必須平行，間隙合理，以免閥門產生過大壓力，甚至開裂。對于脆性材料和強度不高的閥門，尤</span><span style="font-size:16px;">其要注意。須與管子焊接的閥門，應先點焊，再將關閉件全開，然后焊死。</span> 閥門在各類化工活動中十分常見，有“管道咽喉”之稱。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

style="font-size:16px;">閥門密封性原理密封就是防止泄漏，那么閥門密封性原理也是從防止泄漏研究的。閥門的種類繁多，但是基本的作用卻是一致的，那就是連通或者截斷介質流。因此，閥門的密封問題就顯得十分突出。要保證閥門能夠良好的截斷介質流，不發(fā)生泄漏，就要保證閥門的密封完好。而造成閥門泄漏的原因很多，包括結構設計上的不合理、密封接觸面有缺陷、緊固零件發(fā)生松動、閥體與閥蓋間</span><span style="font-size:16px;">的配合不緊密等等，所有這些問題都可能導致閥門密封不好，從而產生泄漏問題。所以，閥門密封技術是關系到閥門性能和質量的一項重要技術，需要進行系統(tǒng)深入的研究。閥門從產生到現(xiàn)在，其密封技術也經歷了很大的發(fā)展。到目前為止，閥門密封技術主要體現(xiàn)在兩大方面，即靜密封和動密封。</span>

style="font-size:16px;">常用閥門介紹閥門種類多、品種復雜，主要有閘閥、截止閥、節(jié)流閥、蝶閥、旋塞閥、球閥、電動閥、隔膜閥、止回閥、安全閥、減壓閥、蒸汽疏水閥和緊急切斷閥等，其中常用的有閘閥、截止閥、節(jié)流閥、旋塞閥、蝶閥、球閥、止回閥、隔膜閥。明確閥門在設備或裝置中的用途確定閥門的工作條件：適用介質的性質、工作壓力、工作溫度和操縱控制方式等。2、正確選擇閥門的類型閥門型式的正確選擇是以設計者對整個生產工藝流程、操作工況的充分掌握為先決條件的，在選擇閥門類型時，設計人員應首先掌握每種閥門的結構特點和性能。確定閥門的端部連接在螺紋連接、法蘭連接、焊接端部連接中，前兩種常用。螺紋連接的閥門主要是公稱通徑在50mm以下的閥門，如果通徑尺寸過大，連接部的安裝和密封十分困難。法蘭連接的閥門，其安裝和拆卸都比較方便，但是較螺紋連接的閥門笨重，價格較高，故它適用于各種通徑和壓力的管道連接。焊接連接適用于較荷刻的條件下，比法蘭連接更為可靠。但是焊接連接的閥門拆卸和重新安裝都比較困難，所以它的使用于通常能長期可靠地運行，或使用條件荷刻、溫度較高的場合。</span>
