一、礦用防爆型電動閘閥詳細介紹
礦用防爆型電動閘閥，帶煤安電動閘閥，防爆礦用電動閘閥，礦用防爆電動閘閥，MZ941H-64C主要用于煤礦，井下，一般這種防爆礦用電動閘閥，帶煤安電動閘閥，礦用防爆電動閘閥電源電壓有380V和660V,這種電動閘閥必須帶有煤安證才能進礦接觸器等組成。控制線為220V，50Hz（特殊訂貨60Hz）；遠程控制為24VDC。調(diào)節(jié)模塊可接收和輸出4～20ma標準信號。電氣元件安裝在一塊可翻轉(zhuǎn)的板上，以便對力矩控制、行程控制器、開度機構進行調(diào)整。按鈕盒上有三個按鈕，中間為現(xiàn)場/遠控轉(zhuǎn)換按鈕，其左邊現(xiàn)場關閥按鈕，右邊為現(xiàn)場開閥按鈕，蓋上按鈕盒為遠方控制，打開蓋子為現(xiàn)場操作。2. 礦用電動閘閥，礦用防爆型電動閘閥，
礦用防爆型電動閘閥特點:
①閥門采用壓力自緊式密封或閥體、閥蓋墊片密封結構，值得信賴！使用安全可靠。
②閥瓣采用雙閘板中間帶萬向頂結構，能自動調(diào)整閥瓣與閥座密封面吻合度，保證閥門的密封。同時此結構維修方便，節(jié)約費用，閥瓣互換性較好。
③閥瓣、閥座密封面用鈷鉻鎢硬質(zhì)合金由等離子噴焊而成，密封面硬度高，耐磨擦，抗擦傷，使用壽命長。
④閥桿用滲氮鋼制成，表面氮化處理，硬度高，抗擦傷，耐腐蝕，使用壽命長。
⑤電動裝置配有轉(zhuǎn)矩控制機構、現(xiàn)場操作機構和手、電動切換機構。除就地操作外，還可以進行遠距離操作、PLC控制、4~20mA電流輸入輸出智能控制等。
⑥手動閥門由手動機構或撞擊時手輪開啟。減小閥門操作力。
⑦閥門可安裝在管道的任何位置，同時根據(jù)介質(zhì)和介質(zhì)的溫度選擇碳鋼或合金鋼閥門。⑧初次安裝和調(diào)試時，必須手動把閥門開到約一半的位置，以免電機相序接反導致閥門或電裝損壞。
