產(chǎn)品介紹
德國RBT進口節(jié)流閥是指通過改變通道面積達到控制或調(diào)節(jié)介質(zhì)流量與壓力的閥門,在管路中主要作節(jié)流使用。最常見的進口節(jié)流閥是采用截止閥改變閥瓣形狀后作節(jié)流用。但用改變截止閥或閘閥開啟高度來作節(jié)流用是極不合適的,因為介質(zhì)在節(jié)流狀態(tài)下流速很高,必然會使密封面沖蝕磨損,失去切斷密封作用。同樣用進口節(jié)流閥作切斷裝置也是不合適的,因此截止閥的流動阻力較高于其它閥門。
Germany imports RBT throttle valve is to control or adjust the media flow and pressure of the valve by changing the channel area, in the pipeline is mainly used for cutting. Inlet throttle valve is the most common used cut-off valve change the valve shape made after cutting with. But by changing the cut-off valve or throttle valve opening height to be used is not appropriate, because the state of media flow in throttling is very high, will make the sealing surface erosion, loss of seal cutting. The same inlet throttle valve as cutting device is not appropriate, so a higher cut-off valve flow resistance in the other valve.
