不銹鋼304電動(dòng)閘閥開(kāi)關(guān)型介紹

一、不銹鋼304電動(dòng)閘閥開(kāi)關(guān)型是又閘閥與電動(dòng)執(zhí)行器組成，控制方式為開(kāi)關(guān)型，閘閥的關(guān)閉件（閘板）沿通路中心線的垂直方向移動(dòng)的閥門，在管路中只能作全開(kāi)或全關(guān)切斷用，不能作調(diào)節(jié)和節(jié)流。需要轉(zhuǎn)很多圈才能實(shí)現(xiàn)閥門的開(kāi)關(guān)。公稱壓力16公斤，密封材質(zhì)為合金鋼，法蘭連接。閥體材質(zhì)為不秀綱，是閘閥中比較常見(jiàn)的一種型號(hào)。

二、不銹鋼304電動(dòng)閘閥開(kāi)關(guān)型具有以下特點(diǎn):

①閥門采用壓力自緊式密封或閥體、閥蓋墊片密封結(jié)構(gòu)，值得信賴！使用安全可靠。 

②閥瓣采用雙閘板中間帶萬(wàn)向頂結(jié)構(gòu)，能自動(dòng)調(diào)整閥瓣與閥座密封面吻合度，保證閥門的密封。同時(shí)此結(jié)構(gòu)維修方便，節(jié)約費(fèi)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(zhǎng)。 

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(zhǎng)。 

⑤電動(dòng)裝置配有轉(zhuǎn)矩控制機(jī)構(gòu)、現(xiàn)場(chǎng)操作機(jī)構(gòu)和手、電動(dòng)切換機(jī)構(gòu)。除就地操作外，還可以進(jìn)行遠(yuǎn)距離操作、PLC控制、4~20mA電流輸入輸出智能控制等。 

⑥手動(dòng)閥門由手動(dòng)機(jī)構(gòu)或撞擊時(shí)手輪開(kāi)啟。減小閥門操作力。 

⑦閥門可安裝在管道的任何位置，同時(shí)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(shí)，必須手動(dòng)把閥門開(kāi)到約一半的位置，以免電機(jī)相序接反導(dǎo)致閥門或電裝損壞。
