GB Malosi ma vaivai Fa'amaufa'ailoga Valves Fa'a'opeopea Va'aiga lautele: Fa'atinoga, Fa'aoga, ma Tulaga Fa'atonu

O le faʻamaufaʻailoga a le atunuʻu vaivai ma faʻamaufaʻailoga faʻafefe polo valve o se valve faʻaaogaina e pulea ai alavai vai, lea e lelei le faʻamaufaʻailogaina ma le laʻititi vai. I totonu o lenei tusiga, o le a matou faʻaalia uiga, talosaga, ma faʻamatalaga autu o faʻatinoga o faʻamaufaʻailoga a le atunuʻu vaivai ma faʻamaufaʻailogaina polo opeopea.

1. Fa'ailoga oloa

O le tulaga fa'ale-atunu'u vaivai ma fa'amaufa'ailoga fa'afefete polo valve o lo'o i ai uiga nei:

-Low vai resistance: O valve polo e sili ona maualalo le tete'e o le vai i totonu o ituaiga valve uma, e o'o lava mo le fa'aititia o le lautele o polo, e la'ititi la latou vai.

-Tatala vave ma faigofie ma tapuni: Afai lava e faʻasolo le 90 ° le valve valve, o le valve polo o le a faʻamaeʻaina le tatalaina atoa poʻo le tapuni atoa gaioiga, faʻafaigofie ona maua vave tatala ma tapuni.

- Lelei faʻamaufaʻailoga faʻamaufaʻailoga: Ua tapunia le nofoa polo valve, faʻatasi ai ma faʻamaufaʻailoga lelei.

2. Fa'aaogaina o Mea

O le faʻamaufaʻailoga a le atunuʻu vaivai ma faʻamaufaʻailoga faʻafefe polo valve e talafeagai mo le suauʻu, kesi masani, vailaʻau, vailaʻau, meaʻai, eletise, vai, metallurgy, ma fale faufale. Flange floating ball valve o se auala masani fesoʻotaʻiga, talafeagai mo tulaga faigaluega eseese.

3. Fa'amatalaga autu o le faatinoga

Nominal pressure (MPa): O le numera o le mamafa o le vaʻavaʻa faʻafefete faʻafefete faʻamaufaʻailoga a le atunuʻu o le 0.6 ~ 42.0 MPa, ma e mafai ona filifilia le maualuga o le mamafa e tusa ai ma tulaga faigaluega eseese.

Fa'atatau le vevela: O le fua fa'atatau o le vevela mo fa'amaufa'ailoga masani a le atunu'u fa'amama ma fa'amaufa'ailoga fa'afefete polo e -196 ℃ ~ 550 ℃, a'o le sulfur tete'e le atunu'u tulaga vaivai ma fa'amaufa'ailoga fa'afefete polo e talafeagai mo kesi masani, suau'u ma isi fa'asalalauga o lo'o iai H2S. ma le CO2.

Fa'asalalauga talafeagai: Fa'amaufa'ailoga a le atunu'u fa'amaufa'ailoga fa'afefe polo e fetaui lelei mo ala fa'asalalau e pei o vai, ausa, suau'u, kesi fa'afefe, ma kesi fa'alenatura.

4. Mea fa'aoga autu

O mea autu vaega o le atunuu tulaga vaivai ma faamaufaailoga opeopea valve e aofia ai carbon sila faasologa, stainless sila faasologa, sulfur resistant faasologa, ma le maualalo-vevela uamea faasologa. O nei mea e mafai ona fetaui ma manaʻoga o tulaga faigaluega eseese, faʻamautinoa le tumau ma le faʻamaoni o le valve.

5. Tulaga Fa'atinoina

O le faʻamaufaʻailoga a le atunuʻu vaivai ma faʻamaufaʻailoga faʻafefe polo valve ua mamanuina ma gaosia e tusa ai ma tulaga faʻapitoa e pei o GB / T12237, GB / T12221, GB / T12224, ma GB / T12220. O nei tulaga faʻamaonia e faʻamaonia ai manaʻoga mo le umi o le fausaga, faʻafesoʻotaʻi flanges, suʻega ma asiasiga o valve, faʻamautinoaina le lelei o oloa.

I le aotelega, o le faʻamaufaʻailoga a le atunuʻu vaivai ma faʻamaufaʻailoga faʻafefe polo valve o se valve e sili ona lelei le faʻatinoga, faʻaaogaina lautele i fanua faʻapisinisi eseese. O le malamalama i ona uiga, faʻaogaina, ma faʻamatalaga autu o faʻatinoga e mafai ona fesoasoani ia i tatou e sili atu le filifilia ma faʻaoga lenei ituaiga valve.
