style="text-indent:25px">ZCRB防爆燃氣緊急切斷閥功能和工作原理：該系列閥門是常開脈沖觸發(fā)式電磁閥，具有事故自鎖和手動復位功能。閥門在日常工作中處于常開狀態(tài)，電磁閥線圈處于斷電狀態(tài)，不消耗電能。當事故發(fā)生時，閥門線圈立即通電，觸發(fā)閥門快速關(guān)閉并進入自鎖狀態(tài)。此時，即使斷電，閥門仍處于自鎖閉合狀態(tài)，不會自動重新打開。該閥采用先導式閥瓣，易于打開。即使壓力達到6bar，也很容易打開。直徑大于DN125。杠桿手柄用于使閥門以較低的力度和速度到達目標開關(guān)。當工作人員處理事故并手動重新打開閥門時，將恢復供氣。可根據(jù)要求提供帶斷電關(guān)閉功能的常閉緊急切斷閥。電磁式燃氣緊急切斷閥廣泛應用于供氣管網(wǎng)系統(tǒng)、燃氣熱能工廠、燃氣鍋爐房及住宅居所等場所。南京防爆緊急切斷閥采購</p><p style="text-indent:25px">傳統(tǒng)結(jié)構(gòu)是在閥瓣上設(shè)置隔膜。南京防爆緊急切斷閥采購</p><p style="text-indent:25px"> 　燃氣緊急切斷閥的結(jié)構(gòu)分類特點：拔銷式：使用一根動鐵心卡住主閥桿使閥門處于打開位置，在需要切斷閥關(guān)閉時，使用電磁線圈產(chǎn)生電磁力拔出動鐵心，使主閥桿落下關(guān)閉閥門。這種結(jié)構(gòu)優(yōu)點是，結(jié)構(gòu)簡單，易于加工和組裝，生產(chǎn)成本相對較低。但缺點是動鐵心摩擦力相對較大，動作時所需電能相對較多。球柵式：使用一組限位用圓球（球柵），在動鐵心的擠壓下固定于限位槽內(nèi)，將閥瓣置于開啟位置，在需要關(guān)閉時，使用電磁線圈產(chǎn)生電磁力拔出動鐵心，圓球在閥桿擠壓下彈出限位槽，閥桿連帶閥瓣落下關(guān)閉閥門。圓球材質(zhì)可根據(jù)需要選用。優(yōu)點是相對于拔銷式，所需電磁力較小，能耗較少。但由于零件較多，且對尺寸要求比較嚴格，為加工和裝配帶來一定的困難。另外，由于限位圓球與閥桿的硬度存在一定差異，若在壓力較高的情況下長時間運行，會在圓球與閥桿接觸面上出現(xiàn)壓痕，增大受力面積，導致阻力的增大，圓球不能脫出限位槽，從而導致不能切斷。因此，球柵式觸發(fā)機構(gòu)多用于低壓燃氣緊急切斷閥。南京防爆緊急切斷閥采購</p><p
