礦用防爆電動閘閥閥門特點:

·                                         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)介質和介質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。
