進口氣動閘閥(德國OLES奧萊斯閥門)
【進口氣動閘閥】詳細(xì)說明:
氣動閘閥,借助壓縮空氣驅(qū)動的閥門,閘閥關(guān)閉時 , 密封面可以只依靠介質(zhì)壓力來密封 , 即依靠介質(zhì)壓力將閘板的密封面壓向另一側(cè)的閥座來保證密封面的密封,這就是自密封。大部分閘閥是采用強制密封的 , 即閥門關(guān)閉時,要依靠外力強行將閘板壓向閥座 , 以保證密封面的密封性。
Pneumatic gate valve, with the help of compressed air driven valve, when the gate valve closes, the sealing surface can only rely on the medium pressure to seal, that is, relying on the medium pressure to press the sealing surface of the gate to the other side of the valve seat to ensure the sealing surface sealing, which is self-sealing. Most gate valves are forced to seal, that is, when the valve closes, the gate must be forced to the seat by external force to ensure the sealing of the sealing surface.
【進口氣動閘閥】用途:
氣動閘閥是一種直角回轉(zhuǎn)結(jié)構(gòu),它與閥門定位器配套使用,可實現(xiàn)比例調(diào)節(jié); V型閥芯適用于各種調(diào)節(jié)場合,具有額定流量系數(shù)大,可調(diào)比大,密封效果好,調(diào)節(jié)性能零敏,體積小,可豎臥安裝。適用于控制氣體、蒸汽、液體等介質(zhì)。
Pneumatic gate valve is a right-angled rotary structure, which can be used with valve positioner to achieve proportional adjustment. V-shaped spool is most suitable for various adjustment occasions, with a large rated flow coefficient, large adjustable ratio, good sealing effect, zero-sensitivity regulation performance, small volume, and can be installed vertically and horizontally. It is suitable for controlling gas, steam, liquid and other media.
【進口氣動閘閥】特點:
1、閘板有兩個密封面,密封面形成楔形、楔形角隨閥門參數(shù)而異, 通常為5°
2、楔式閘閥的密封原理是靠楔形閘板上兩個密封面和閥體上兩個 密封面楔入時的緊密結(jié)合,從而達到 密封性能的。
3、楔式閘閥根據(jù)閥桿帶動閘板啟閉方式的不同,可分為明桿閘閥 (升降桿閘閥)和暗桿閘閥(旋轉(zhuǎn)桿閘閥)。
4、楔式閘閥根據(jù)閘板結(jié)構(gòu)形式的不同,可分為彈性閘板閘閥和剛 性閘板閘閥
5、閥體為鑄造成型,閥體與閥蓋采用螺栓連接,中法蘭采用纏繞 式墊片密封,客戶有特殊要求時也可采用金屬環(huán)連接。
6、通道流暢,流量系數(shù)小。密封面受介質(zhì)的沖刷和侵蝕小。
7、密封面采用合金鋼或硬質(zhì)合金,耐磨、抗擦傷性能好。
【進口氣動閘閥】應(yīng)用范圍:
