高性能密閉蝶閥，普遍适用于建材、玻(bō)璃、礦山、電力、輕工、造紙等行業的通風、環保工(gōng)程等管道系統中。對管道(dào)中氣體介質(zhì)按不同控制信号調節(jiē)流量大小和切斷。
This valve is widely used in the pipe system such as venting and environment protection in building material, glass, mining, power, light industry and papermaking departments. It can change the flow and cut off gas medium in the pipe by the different control signal.
結(jié)構特點：
Structure characteristic:
高(gāo)性能密閉蝶閥具有重量輕、結構緊(jǐn)湊、耐磨損、流阻損失小、工作壓力高、密封壓差大、操作靈活、指示方位(wèi)明确、維(wéi)護方便、使用(yòng)壽命長(zhǎng)等優點。可(kě)任意角度安裝，特别适(shì)用于調(diào)節切斷和要求快速自保的場合。配用DKJ、ZKJ、伯(bó)納德等電動執行(háng)器(qì)及有關配件，可(kě)實現(xiàn)手動、自動無(wú)幹擾切換，微機程控、自動控制或中央集中控制，是實(shí)現自動化控制操(cāo)作、調節流量的理想設備。
The valve has the features of lightweight, compact structure, endurance, little in the lost of flow resistance, high working pressure, flexible operation, definite direction, easy to maintenance and long life. It can be installed at any angle. It is suitable in the condition of adjusting, cutting off and self-protecting quickly. The valve is used with DKJ, ZKJ, Bernard electric actuator and other accessory to form a complete set to realize manual and automatic exchange without interference, micro-computer long-range control, automatic control or center concentrating control. It is the ideal equipment of realizing operation of automatic control and adjusting flow.
