雙關(guān)雙斷閥在AMOT的應(yīng)用

                       雙關(guān)雙斷閥在AMOT的應(yīng)用

                    上海申弘閥門有限公司


      AMOT采購那一臺(tái)DN50,壓力為16公斤，閥材質(zhì)為鑄鋼，應(yīng)用在控制系統(tǒng)中，將軍閥、雙關(guān)雙斷閥、雙密封導(dǎo)軌閥適用于：煤油、原油、輕質(zhì)油、天然氣、液化氣、管道煤氣、化工介質(zhì)等管道上，作為截?cái)嘟橘|(zhì)的理想裝置。上海申弘閥門有限公司主營(yíng)閥門有：減壓閥(氣體減壓閥,可調(diào)式減壓閥,波紋管減壓閥,活塞式減壓閥,蒸汽減壓閥,先導(dǎo)式減壓閥,空氣減壓閥,氮?dú)鉁p壓閥,水用減壓閥,自力式減壓閥,比例減壓閥)、安全閥、保溫閥、低溫閥、球閥、截止閥、閘閥、止回閥、蝶閥、過濾器、放料閥、隔膜閥、旋塞閥、柱塞閥、平衡閥、調(diào)節(jié)閥、疏水閥、管夾閥、排污閥、排氣閥、排泥閥、氣動(dòng)閥門、電動(dòng)閥門、高壓閥門、中壓閥門、低壓閥門、水力控制閥、真空閥門、襯膠閥門、襯氟閥門。管道減壓是儲(chǔ)罐區(qū)管匯設(shè)計(jì)中需要重點(diǎn)考慮的問題，即當(dāng)罐前閥關(guān)閉后，管網(wǎng)中仍然充滿了介質(zhì):隨著環(huán)境溫度的升高，管網(wǎng)中介質(zhì)的壓力會(huì)迅速增大;當(dāng)溫差變化較大時(shí)，增加的壓力會(huì)超過管道的承受能力，容易造成管道泄漏因此，管道應(yīng)配備減壓設(shè)備管道 減 壓 設(shè)計(jì).在主切斷閥的上、下游之間連接管道減壓系統(tǒng)，該系統(tǒng)由兩個(gè)截?cái)嚅y(閘閥、球閥或截止閥)及這兩個(gè)截?cái)嚅y之間的一個(gè)減壓閥組成該套系統(tǒng)成本高，而且占用空間，不方便現(xiàn)場(chǎng)管理。主切斷閥選用雙密封導(dǎo)軌閥的管道道設(shè)計(jì)原理，減壓系統(tǒng)附在主切斷閥上，其設(shè)計(jì)結(jié)構(gòu)簡(jiǎn)單，占用空間小，且成本低廉。
     特 點(diǎn)：
①閥門在開關(guān)過程中，閥體密封面與滑片密封面沒有任何接觸，因此，密封面無摩擦、磨損、閥門的使用壽命長(zhǎng)，開關(guān)力矩小；
②閥門在維修時(shí)，不需將閥門從管線上拆下，只需將閥門底蓋拆開，調(diào)換一對(duì)滑片即可，維修十分方便；
③閥體及旋塞為全通徑，介質(zhì)在通過閥門時(shí)無流阻，并且可通球?qū)艿肋M(jìn)行清洗，克服了縮徑閥門的缺點(diǎn)；     
     ④ 閥體內(nèi)腔鍍有硬鉻，密封區(qū)域堅(jiān)硬光滑；
⑤ 滑片上的彈性密封采用氟橡膠，并且模壓成型在滑片表面溝槽中。具有防火功能的金屬對(duì)金屬的密封作為彈性密封的背襯；
⑥ 閥門具有自動(dòng)泄放裝置（備選），在閥門*關(guān)閉后，防止閥腔異常升壓并檢驗(yàn)閥門的效果；
⑦ 閥門開關(guān)指示器與開關(guān)位置同步，可以準(zhǔn)確顯示閥門的開關(guān)狀態(tài)。
In 1948 AMOT began operating in Richmond, California USA with the invention of the industrial thermostatic valve developed for the marine industry. Today the AMOT thermostatic valve family is the accepted standard in various industrial applications around the world. Our products and solutions are still breaking new ground in temperature and pressure sensing and control as well as in new areas such as diesel engine safety and condition monitoring technologies. Our team of highly skilled engineers and manufacturing experts are highly focused and directed towards developing highly specialized controls solutions across a wide variety of applications and industries. We continue to partner with the technical teams of our customers to ensure the solutions we provide meet or exceed their expectations. 




In 2007 the AMOT Group expanded with the acquisition of Roda Deaco Valve Company, of Edmonton, Canada and again in 2008 with the acquisition of Chalwyn Ltd. of Poole, Dorset UK. With the addition of these two product lines and the expertise acquired, AMOT is the leading manufacturer of emergency diesel engine shut down systems in the world.  

Our global capability is unmatched. With manufacturing facilities and engineering design capability in Houston, TX USA, Edmonton, Canada, Bury St. Edmunds, United Kingdom and Shanghai, China we have the local support and global infrastructure to meet your needs effectively and efficiently
