本閥門(mén)是一種橡膠（NBR）密封蝶閥，廣泛應(yīng)用于電力、水力、冶金、化工、城建等行業(yè)的給排水管路系統(tǒng)，作為控制介質(zhì)流量的啟閉或調(diào)節(jié)裝置。溝槽式（卡箍）蝶閥是引進(jìn)美國(guó)和德國(guó)同類(lèi)先進(jìn)產(chǎn)品而設(shè)計(jì)制造的一種新型連接閥門(mén)。它具有一安裝快速、簡(jiǎn)易、安全不受安裝場(chǎng)地限制、便于管道與閥門(mén)的維修保養(yǎng)，有隔振隔音與一定的角度范圍內(nèi)克服管道連接同軸而產(chǎn)生的偏差。解決溫差所產(chǎn)生的熱脹冷縮等優(yōu)點(diǎn)。

The valve is a rubber (NBR) sealed butterfly valve, which is widely used in water supply and drainage pipeline systems in electric power, hydraulic, metallurgy, chemical industry, urban construction and other industries as an opening and closing or regulating device for controlling medium flow. Grooved (clamp) butterfly valve is a new connecting valve designed and manufactured by introducing similar advanced products from the United States and Germany. The utility model has the advantages of fast, simple and safe installation, is not limited by the installation site, is convenient for the maintenance of pipelines and valves, has vibration isolation and sound insulation, and overcomes the deviation caused by the coaxial connection of pipelines within a certain angle range. Solve the advantages of thermal expansion and cold contraction caused by temperature difference.
