進(jìn)口偏心蝶閥質(zhì)優(yōu)價(jià)廉德國(guó)洛克

一、進(jìn)口偏心蝶閥產(chǎn)品簡(jiǎn)介：

德國(guó)《LOCKE》洛克進(jìn)口偏心蝶閥（Eccentric butterfly valve）是為了解決同心蝶閥的蝶板與閥座的擠壓?jiǎn)栴}、由此產(chǎn)生了單偏心蝶閥、其結(jié)構(gòu)特征為閥桿軸心偏離了蝶板中心、從而使蝶板上下端不再成為回轉(zhuǎn)軸心、分散、減輕了蝶板上下端與閥座的過(guò)度擠壓。但由于單偏心構(gòu)造在閥門(mén)的整個(gè) 開(kāi)關(guān)過(guò)程中蝶板與閥座的刮擦現(xiàn)象并未消失、在應(yīng)用范圍上和同心蝶閥大同小異、故采用不多。

The eccentric butterfly valve imported by Locke in Germany is to solve the extrusion problem between the butterfly plate and the valve seat of the concentric butterfly valve, resulting in a single eccentric butterfly valve. Its structural feature is that the valve stem axis deviates from the center of the butterfly plate, so that the upper and lower ends of the butterfly plate are no longer the rotation axis, dispersed, and the excessive extrusion between the upper and lower ends of the butterfly plate and the valve seat is reduced. However, due to the single eccentric structure in the whole process of valve opening and closing, the scraping phenomenon between the butterfly plate and the valve seat has not disappeared, and it is similar to the concentric butterfly valve in the application scope, so it is rarely used.
