進(jìn)口鍛鋼法蘭截止閥
德國(guó)巴赫進(jìn)口鍛鋼法蘭截止閥概述：
進(jìn)口鍛鋼焊接截止閥有三種閥蓋設(shè)計(jì)形式。*種是螺栓式閥蓋，按這種設(shè)計(jì)形式設(shè)計(jì)的閥門，其閥體與閥蓋用螺栓螺母連接，纏繞式墊片 (316夾柔性石墨制造)密封。客戶有特殊要求時(shí)也可采用金屬環(huán)連接。第二種設(shè)計(jì)形式是焊接式閥蓋，按這種設(shè)計(jì)形式的閥門，其閥體與閥蓋用螺紋連接，全焊密封。客戶有特殊要求時(shí)也可采用全焊接連接。第三種是壓力自緊式閥蓋，按這種設(shè)計(jì)形式設(shè)計(jì)的閥門，其閥體與閥蓋用螺紋連接，內(nèi)壓自密封環(huán)密封。
Forged steel flange stop valve
Germany Bach imported forged steel flange valve overview:
Forged steel welding globe valve valve cover design in three forms. The first is a bolt type valve cover, according to the design of the design of the valve, the valve body and valve cover with bolts and nuts connected to the winding gasket (316 folder flexible graphite manufacturing) seal. Customers can also use the special requirements of the metal ring connection. The second form of design is the welded valve cover, according to the design of the form of the valve, the valve body and valve cover with threaded connections, all welded seal. Customers can also use special requirements when full welding connection. The third is the pressure from the valve cover, according to the design of the design of the valve, the valve body and the valve cover is connected with the screw, the internal pressure self sealing ring seal.
進(jìn)口鍛鋼法蘭截止閥的定義：
1、結(jié)構(gòu)緊湊、啟閉性好、高度小、維護(hù)方便。
2、閥瓣可變換為節(jié)流型、針型、球型和止回型。
3、具有抗氣蝕作用耐磨、耐蝕、耐沖刷、使用壽命長(zhǎng)。
4、密封面為硬質(zhì)合金不易磨損、擦傷、密封性能好。壽命長(zhǎng)。
5、適用于水、蒸汽、油品管路上、具有耐高溫、耐高壓的特點(diǎn)。
6、閥桿底部的啟閉處為半球體形閥瓣、閥桿及閥瓣表面為硬質(zhì)合金層。
7、流量阻力小、關(guān)閉更嚴(yán)密、潤(rùn)滑油不易流失、摩擦力小、閥門啟閉輕松、動(dòng)作靈敏。
The definition of forged steel flange valve:
1, compact structure, good opening and closing, small height, easy maintenance.
2, the valve flap can be transformed into the throttle type, needle type, ball type and check type.
3, with cavitation erosion resistance, corrosion resistance, erosion resistance, long service life.
4, sealing surface is hard to wear, abrasion, good sealing performance. Long life.
5, suitable for water, steam, oil pipeline, with high temperature, high pressure characteristics.
6, the stem at the bottom of the opening and closing of the valve flap for the hemisphere, valve stem and valve surface is cemented carbide layer.
7, flow resistance is small, close more tightly, the oil is not easy to loss, friction small, easy to open and close the valve, action sensitive.
