易燃易爆介質(zhì)-波紋管閘閥

易燃易爆介質(zhì)-波紋管閘閥

應(yīng)用:適用于易燃易爆工況,如熱油,氫氣等。

型號: VK101,VK102,VK103...

口徑: 2”-24“

壓力: 150LB-600LB

材質(zhì): LCB, WCB, CF8,CF8M

使用溫度: -38 to 425 C

應(yīng)用介質(zhì): 導(dǎo)熱油,高溫蒸汽,氫氣等


設(shè)計規(guī)范:

設(shè)計制造:JB/T 11487-2013, API600

結(jié)構(gòu)長度:GB/T 12221, ASME B16.10

連接尺寸:HG/T 20592, ASME B16.25

壓力-溫度: GB/T 9131 ASME B16.34 HG 20592

試驗-檢驗: GB/T13927 GB/T 9092 API 598

氦質(zhì)譜檢漏:API 602 MSS SP-117


設(shè)計特點: 

1.        采用雙層波紋管結(jié)構(gòu),閥門結(jié)構(gòu)合理,更加緊湊;

2.        本公司設(shè)計制造的雙波紋管閘閥安裝高度較同類產(chǎn)品下降20%~30%;

3.        采用雙層波紋管結(jié)構(gòu),閥門在開關(guān)過程中對波紋管的受力減小,

且受力更均勻,延長其使用壽命;

4.        采用雙層波紋管,密封更加可靠。閥門經(jīng)氦檢漏,實現(xiàn)零泄漏,

特別使用于易燃、易爆、劇毒介質(zhì)的管路,環(huán)保又安全;

5.     采用直通式結(jié)構(gòu),優(yōu)化流道設(shè)計,介質(zhì)過流阻力小,流量系數(shù)大,使用更節(jié)能;

6.     采用填料、雙波紋管及閥桿等多層密封,使閥門達(dá)到真正的零泄漏

Application: For flammable and explosive working conditions, e.g. hot oil, hydrogen, etc.
Design features.
1. the use of double bellows structure, the valve structure is reasonable and more compact.
2. the installation height of the double bellow gate valve designed and manufactured by our

company is 20%~30% lower than that of similar products.
3. the use of double bellows structure, the valve in the process of opening and closing the

force on the bellows is reduced, and the force is more uniform, extending its service life.
4. the use of double-layer bellows, more reliable sealing. The valve is leak-tested by helium

to achieve zero leakage.Especially used in flammable, explosive, highly toxic media pipeline,

 environmental protection and safety.

5. adopt straight-through structure, optimize the flow channel design, the medium

overflow resistance is small, the flow coefficient is large, use more energy-saving.
6. the use of packing, double bellows and stem multi-layer seal, so that the valve to

achieve a true zero leakage
