三偏心硬密封蝶閥詳細(xì)介紹:
三偏心硬密封蝶閥產(chǎn)品結(jié)構(gòu)及性能簡(jiǎn)介:
產(chǎn)品,我公司生產(chǎn)的長(zhǎng)壽命、節(jié)能型蝶閥。產(chǎn)品符合國(guó)家標(biāo)準(zhǔn)JB/T8527-97(金屬密封蝶閥),GB/T13927-92(通用閥門壓力試驗(yàn))標(biāo)準(zhǔn)及閥門其他相關(guān)標(biāo)準(zhǔn)的規(guī)定。
本產(chǎn)品有閥體、蝶板、密封圈、傳動(dòng)機(jī)構(gòu)等主要部件組成。其結(jié)構(gòu)采用三維偏心原理設(shè)計(jì),彈性密封和硬軟多層密封兼容的加工新工藝,使蝶閥在運(yùn)行工作時(shí),減少其扭矩力,達(dá)到省力、節(jié)能之功能。從而確保整體的抗腐蝕、耐高溫、抗磨損的可靠性。
其主要性能特點(diǎn)是:
1、結(jié)構(gòu)*、型小輕便、操作靈活、省力、方便
2、密封可靠,可達(dá)到氣密封無(wú)泄漏;
3、流量特性趨于直線調(diào)節(jié)性;
4、采用三偏原理,使密封面近似零磨損延長(zhǎng)了閥門的使用壽命;
5、應(yīng)用范圍廣。如:可用于水、蒸汽、油品、空氣、煤氣等介質(zhì)。
6、適用不同溫度及6.4MPa以下的壓力等級(jí),耐腐蝕等各種介質(zhì)。
