以上各種連接形式，都是利用外力來抵消介質壓力，實現密封的。下面介紹利用介質壓力進行自緊的連接形式。它的密封圈裝在內錐體處，跟介質相向的一面成一定角度，山東橡膠軟接頭閥門直銷，介質壓力傳給內錐體，又傳遞給密封圈，在一定角度的錐面上，產生兩個分力，一個與閥體中心線平行向外，另一個壓向閥體內壁。后面這個分力便是自緊力。介質壓力愈大，自緊力也愈大。所以這種連接形式，適合于高壓閥門。它比法蘭連接，山東橡膠軟接頭閥門直銷，要節(jié)省許多材料和人力，但也需要一定的預緊力，以便在閥內壓力不高時，使用可靠。利用自緊密封原理做成的閥門，山東橡膠軟接頭閥門直銷，一般是高壓閥門。 </p> <p> 閥門連接的形式還很多，例如有的不必拆除的小閥門，跟管子焊接在一起；有的非金屬閥門，采用承插式連接，等等。閥門使用者要根據具休情況具體對待。山東橡膠軟接頭閥門直銷</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

自動閥是指不需要外力驅動，而是依靠介質自身的能量來使閥門動作的閥門。如安全閥、減壓閥、疏水閥、止回閥、自動調節(jié)閥等。 </p> <p> (2) 動力驅動閥：動力驅動閥可以利用各種動力源進行驅動。分為電動閥、氣動閥、液動閥等。電動閥：借助電力驅動的閥門。氣動閥：借助壓縮空氣驅動的閥門。液動閥：借助油等液體壓力驅動的閥門。 </p> <p> 此外還有以上幾種驅動方式的組合，如氣-電動閥等。 </p> <p> (3) 手動閥：手動閥借助手輪、手柄、杠桿、鏈輪，由人力來操縱閥門動作。當閥門啟閉力矩較大時，可在手輪和閥桿之間設置齒輪或蝸輪減速器。必要時，也可以利用萬向接頭及傳動軸進行遠距離操作。山東橡膠軟接頭閥門直銷</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

（1）截斷類：如閘閥、截止閥、旋塞閥、球閥、蝶閥、針型閥、隔膜閥等。截斷類閥門又稱閉路閥，截止閥，其作用是接通或截斷管路中的介質。 </p> <p> (2) 止回類：如止回閥，止回閥又稱單向閥或逆止閥，止回閥屬于一種自動閥門，其作用是防止管路中的介質倒流、防止泵及驅動電機反轉，以及容器介質的泄漏。水泵吸水關的底閥也屬于止回閥類。 </p> <p> (3) 安全類：如安全閥、防爆閥等。安全閥的作用是防止管路或裝置中的介質壓力超過規(guī)定數值，從而達到安全保護的目的。 </p> <p> (4) 調節(jié)類：如調節(jié)閥、節(jié)流閥和減壓閥，其作用是調節(jié)介質的壓力、流量等參數。 </p> <p> (5) 分流類：如分配閥、三通閥、疏水閥。其作用是分配、分離或混合管路中的介質。 </p> <p> (6）特殊用途類：如清管閥、放空閥、排污閥、排氣閥、過濾器等。排氣閥是管道系統(tǒng)中必不可少的輔助元件，廣泛應用于鍋爐、空調、石油天然氣、給排水管道中。往往安裝在制高點或彎頭等處，排除管道中多余氣體、提高管道路使用效率及降低能耗。 </p><p> 閥門介紹 </p> <p> 閥門是用來開閉管路、控制流向、調節(jié)和控制輸送介質的參數（溫度、壓力和流量）的管路附件。根據其功能，可分為關斷閥、止回閥、調節(jié)閥等。閥門是流體輸送系統(tǒng)中的控制部件，具有截止、調節(jié)、導流、防止逆流、穩(wěn)壓、分流或溢流泄壓等功能。用于流體控制系統(tǒng)的閥門，從**簡單的截止閥到極為復雜的自控系統(tǒng)中所用的各種閥門，其品種和規(guī)格相當繁多。閥門可用于控制空氣、水、蒸汽、各種腐蝕性介質、泥漿、油品、液態(tài)金屬和放射性介質等各種類型流體的流動。閥門根據材質還分為鑄鐵閥門，鑄鋼閥門，不銹鋼閥門（201、304、316等），鉻鉬鋼閥門，鉻鉬釩鋼閥門，雙相鋼閥門，塑料閥門，非標訂制閥門等。

閥門的密封性能是指閥門各密封部位阻止介質泄漏的能力，它是閥門**重要的技術性能指標。閥門的密封部位有三處：啟閉件與閥座兩密封面間的接觸處；填料與閥桿和填料函的配合處；閥體與閥蓋的連接處。其中前一處的泄漏叫做內漏，也就是通常所說的關不嚴，它將影響閥門截斷介質的能力。對于截斷閥類來說，內漏是不允許的。后兩處的泄漏叫做外漏，即介質從閥內泄漏到閥外。外漏會造成物料損失，污染環(huán)境，嚴重時還會造成惡事件。對于易燃易爆、或有放射的介質，外漏更是不能允許的，因而閥門必須具有可靠的密封性能。浙江閥門價格</p><p
