style="text-indent:25px">鍛鋼閘閥按密封面配置可分為楔式閘板式鍛鋼閘閥和平行閘板式鍛鋼閘閥。楔式閘板式鍛鋼閘閥又可分為:單閘板式、雙閘板式和彈性閘板式；平行閘板式鍛鋼閘閥可分為單閘板式和雙閘板式。 1）平行式鍛鋼閘閥：密封面與垂直中心線平行，即兩個(gè)密封面互相平行的鍛鋼閘閥。在平行式鍛鋼閘閥中，以帶推力楔塊的結(jié)構(gòu)較為常為常見，既在兩閘板中間有雙面推力楔塊，這種鍛鋼閘閥適用于低壓中小口徑（DN40—300mm）鍛鋼閘閥。也有在兩閘板間帶有彈簧的，彈簧能產(chǎn)生予緊力，有利于閘板的密封。 2）楔式鍛鋼閘閥：密封面與垂直中心線成某種角度，即兩個(gè)密封面成楔形的鍛鋼閘閥。密封面的傾斜角度一般有2°52′，3°30′，5°，8°，10°等，角度的大小主要取決于介質(zhì)溫度的高低。般工作溫度愈高，所取角度應(yīng)愈大，以減小溫度變化時(shí)發(fā)生楔住的可能性。在楔式鍛鋼閘閥中，又有單閘板，雙閘板和彈性閘板之分。單閘板楔式鍛鋼閘閥，結(jié)構(gòu)簡(jiǎn)單，使用可靠，但對(duì)密封面角度的精度要求較高，加工和維修較困難，溫度變化時(shí)楔住的可能性很大。日本YAMATAKE閥門價(jià)格</p><p style="text-indent:25px">日本YAMATAKE閥門價(jià)格</p><p style="text-indent:25px">隨著市場(chǎng)上對(duì)于氣動(dòng)蝶閥越來(lái)越高的使用率，已經(jīng)促進(jìn)了它慢慢成為人們非常實(shí)用的一種工具了。對(duì)于氣動(dòng)蝶閥的定時(shí)清潔與保養(yǎng)就顯得尤為重要了。氣動(dòng)蝶閥的保養(yǎng)維護(hù)的方法： 1、安裝前，必須仔細(xì)核對(duì)本閥標(biāo)志的壓力，通徑是否符合使用要求，避免運(yùn)輸過(guò)程所造成的損傷，并去除閥件的污垢。 2、安裝時(shí)，可將閥門按連接方式直接裝置在管路上。一般情況下，可安裝在管路任意位置上，但需便于操作的檢修，注意截止閥介質(zhì)流向應(yīng)是縱閥瓣下面往上流，升降式止回閥只能水平安裝。 3、填料壓蓋的螺栓應(yīng)均勻地?cái)Q緊，不應(yīng)壓成歪狀態(tài)，以免碰傷阻礙閥桿運(yùn)動(dòng)或造成泄漏。 4、氣動(dòng)蝶閥使用時(shí)，只作全開或全閉，不允許做調(diào)節(jié)流量用，以免密封面受沖蝕，加速磨損。閘閥和上螺紋截止閥內(nèi)有倒密封裝置，手輪旋至頂上位置擰緊，即可阻止介質(zhì)從填料處泄漏。 5、氣動(dòng)蝶閥開、關(guān)時(shí)應(yīng)用手輪，請(qǐng)勿借助杠桿或其它工具，以免損壞閥件。手輪順時(shí)針旋轉(zhuǎn)為關(guān)閉，反之為開啟。 6、長(zhǎng)期存放的閥門，應(yīng)作定期檢查，對(duì)外露的加工表面須保持清潔，去除污垢，存放時(shí)球閥應(yīng)兩端堵塞并處于開啟狀態(tài)，氣動(dòng)蝶閥，通道的兩端應(yīng)堵塞并處于關(guān)閉狀態(tài)，整齊地存放在室內(nèi)通風(fēng)干燥的地方，嚴(yán)禁堆置或露天存放。日本YAMATAKE閥門價(jià)格</p><p
