style="font-size:16px;">內螺紋閘閥，也叫截門，是使用的一種閥門，屬于強制密封式閥門，它的閉合原理是，依靠閥杠壓力，使閥瓣密封面與閥座密封面緊密貼合，阻止介質流通。其按不同方式分為多個種類。內螺紋閘閥的啟閉件是塞形的閥瓣，密封面呈平面或錐面，閥瓣沿流體的中心線作直線運動。閥桿的運動形式，有升降桿式（閥桿升降，手輪不升降），也有升降旋轉桿式（手輪與閥桿一起旋轉升降，螺母設在閥體上）。紋管截止閥只適用于全開和全關，不允許作調節(jié)和節(jié)流。手輪、手柄操作的紋管截止閥可安裝在管道的任何位置上。手輪、手柄及傳動機構，不允許作起吊用。介質的流向應與閥體所示箭頭方向一致。內螺紋閘閥，也叫截門，是使用*****的一種閥門，它之所以廣受歡迎，是由于開閉過程中密封面之間摩擦力小，比較耐用，開啟高度不大，制造容易，維修方便，不僅適用于中低壓，而且適用于高壓。它的閉合原理是，依靠閥杠壓力，使閥瓣密封面與閥座密封面緊密貼合，阻止介質流通。內螺紋閘閥只許介質單向流動，安裝時有方向性。它的結構長度大于閘閥，同時流體阻力大，長期運行時，密封可靠性不強。</span>

style="font-size:16px;">彈性座封閘閥又被稱為軟密封閘閥，是普通中低壓閥門的更新?lián)Q代的產品，被稱為綠色環(huán)保產品，被用于飲用水，給排水、污水處理、消防、能源系統(tǒng)等流體管道上作為截流裝置使用。彈性座封閘閥主要零部件有閥體、閥蓋、閥桿及閘板等，閘板采用球墨鑄鐵外全覆無毒橡膠（直接硫化丁腈橡膠或三元已有丙橡膠）制作而成。整個閥門的密封主要依靠橡膠閘板與鑄件接觸，通過橡膠因受力而產生微量彈性變形達到良好的效果，密封可靠，可達到零泄漏,而且摩擦因很小，磨損小，閥門在啟閉時力矩小，操作輕便，使用壽命長，無污染，耐蝕且外形美觀。平底式閥座傳統(tǒng)的金屬閘閥常常在通水清洗后即因外物如石頭，木塊、水泥、鐵屑、雜物等淤積于閥底凹槽內，容易造成無法開關緊密，而形成漏水現(xiàn)象。彈性座封閘閥采用內腔底部無凹槽，</span><span style="font-size:16px;">底部與水管相同的平底設計，不易造成雜物淤積，密封始終如一。</span> </p><p><span style="font-size:16px;">閘閥安裝注意事項1.安裝前須檢查閥門腔內和密封面等部位，不允許有污物或砂粒附著。2.各連接部位螺栓，要求均勻擰緊。3.檢查填料部位要求壓緊，既保證填料的密封性，也要保證閘板開啟靈活。4.用戶在安裝鍛鋼閘閥前，必須校對閥門型號，連接尺寸及注意介質流向，保證與閥門要求一致性。5.用戶在安裝鍛鋼閘閥時，必須預留閥門驅動的必要空間。6.驅動裝置的接線須按線路圖進行。7.鍛鋼閘閥必須定期保養(yǎng)，不得隨意碰撞及擠壓，以免影響密封。很多閥門能夠適應多種工況，但是如果選擇不合理，閥門的性能和使用壽命會大打折扣。正確、合理的選擇閥門，首先要了解閥門各零部件的材質適應的工況，根據(jù)其使用范圍進行選擇才能使其發(fā)揮比較好性能。閥體、閥蓋和閥瓣是閥門主要零件，直接承受介質壓力，</span><span

style="font-size:16px;">閘闊的種類,按密封面配置可分為楔式閘板式閘閥和平行閘板式閘閥,楔式閘板式閘閥又可分為:單閘極式、雙閘板式和彈性閘板式；平行閘板式閘閥可分為單閘板式和雙閘板式。按閥桿的螺紋位置劃分，可分為明桿閘閥和暗桿閘閥兩種。法蘭閘閥整體包膠：閘板采用***的橡膠進行整體內、外包膠，歐洲前列的橡膠硫化技術使得硫化后的閘板能夠保證精確的幾何尺寸，且橡膠與球墨鑄閘板接著牢靠，不易脫落及彈性記憶佳。精鑄閥體：閥體采用精密鑄造，精確的幾何尺寸使得閥體內部無需任何精加工即可保證閥門的密封性。閘閥具有以下優(yōu)點1、流體阻力小,密封面受介質的忡刷和侵蝕小。2、開閉較省力。3、介質流向不受限制,不擾流、不降低壓力。4、形體簡單,結構長度短，制造工藝性好，適用范圍廣。</span>
