進(jìn)口鍛鋼焊接截止閥
德國(guó)巴赫進(jìn)口鍛鋼焊接截止閥概述：
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?？蛻粲刑厥庖髸r(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?？蛻粲刑厥庖髸r(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 welded globe valve
Overview of imported Bach forged steel welded globe valves:
There are three types of valve cover design for imported forged steel welding globe valve. 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)口鍛鋼焊接截止閥的定義：
1、產(chǎn)品設(shè)計(jì)制造按ANSIB16.34、E101標(biāo)準(zhǔn)，可與進(jìn)口設(shè)備配備使用。
2、閥門中腔采用壓力自緊式密封結(jié)構(gòu)，內(nèi)腔壓力越高密封性能越好。
3、閥瓣和閥座的密封面采用司太立（slite）鈷基硬質(zhì)合金堆焊而成。
4、閥蓋填料函深度合理，填料加緩蝕劑，密封可靠，開關(guān)平穩(wěn)。
5、閥門具有上密封結(jié)構(gòu)，保證閥門開啟運(yùn)行時(shí)不經(jīng)閥桿外漏。
The definition of the cut-off valve welding forged steel:
1, product design and manufacture according to ANSIB16.34, E101 standard, can be equipped with imported equipment.
2, the valve cavity pressure self sealing structure, the higher the pressure inside the sealing performance is better.
3, the valve and the valve seat sealing surface with Slite (Slite) cobalt based alloy welding and.
4, the valve cover packing depth is reasonable, filler and corrosion inhibitor, reliable sealing, stable switch.
5, the valve has a sealing structure to ensure that the valve is not open to the outside of the valve stem when running.
