Fa'atomuaga o mea e fa'amau ai alavai—TWS Valve

O mea fa'amau fa'amau o se vaega taua o fa'amaufa'ailoga valve. O a mea e fa'amau ai valve? Matou te iloa o mea faʻamau faʻamaufaʻailoga e vaevaeina i ni vaega se lua: uʻamea ma le leai. O loʻo i lalo se faʻamatalaga puupuu i tulaga faʻaogaina o mea faʻamaufaʻailoga eseese, faʻapea foʻi ma ituaiga valve masani.

 

1. Pa'u fa'akomepiuta

O mea fa'apitoa o le pa'u fa'apipi'i e pei o le suau'u, fa'afefe vevela ma fa'ama'i e sili atu nai lo le pa'u fa'anatura. E masani lava, o le faʻaaogaina o le vevela o le paʻu gaosia o le t≤150 ℃, ma o le vevela o le paʻu faʻanatura o le t≤60 ℃. Faʻaaogaina le paʻu e faʻamaufaʻailogaina ai le kelope,pa'u nofoia alatoto faitotoa, alatoto o le diaphragm,ralafa'a lele lele, ruber nofo i le alavai siaki suigi (siaki valve), pine faʻamau ma isi vaʻa faʻatasi ma le mamafa PN≤1MPa.

2. Nailoni

O le nailon o lo'o iai uiga o le fa'asa'o la'ititi ma le lelei o le fa'afefe. O le nailoni e masani ona faʻaaogaina mo valve polo ma valve globe ma le vevela t≤90℃ ma le mamafa PN≤32MPa.

3. PTFE

PTFE e masani ona faʻaaogaina mo valve kelope,alatoto faitotoa, valve polo, ma isi ma le vevela t≤232 ℃ ma le mamafa o le PN≤6.4MPa.

4. Uamea lafo

E fa'aaogaina le u'ameaalavai faitotoa, valve globe, valve plug, ma isi mea mo le vevela t≤100 ℃, fa'aigoa fa'aoso PN≤1.6MPa, kesi ma le suauʻu.

5. u'amea Babbitt

O loʻo faʻaogaina le uʻamea Babbitt mo le ammonia globe valve ma le vevela t-70 ~ 150 ℃ ma le mamafa PN≤2.5MPa.

6. apamemea apamemea

O mea masani mo apamemea apamemea 6-6-3 apa apamemea ma 58-2-2 apamemea manganese. O le u'amea apamemea e lelei le ofuina ma e talafeagai mo le vai ma le ausa ma le vevela t≤200℃ ma le mamafa PN≤1.6MPa. E masani ona faʻaaogaina ialatoto faitotoa, valve kelope,siaki valve, alatoto fa'apipi'i, ma isi.

7. Chrome uamea uamea

O togi masani o le chromium stainless steel o le 2Cr13 ma le 3Cr13, lea na tineia ma faʻafefe, ma e lelei le faʻafefe. E masani ona faʻaaogaina i valve mo faʻasalalauga e pei o le vai, ausa ma le suauʻu ma le vevela t≤450℃ ma le mamafa PN≤32MPa.

8. Chromium-nickel-titanium sila uamea

O le faʻaaogaina masani o le chromium-nickel-titanium stainless steel o le 1Cr18Ni9ti, lea e lelei le faʻafefeteina, faʻafefeteina ma le vevela. E talafeagai mo le ausa, nitric acid ma isi ala o faasalalauga ma le vevela t≤600 ℃ ma le mamafa o le mamafa PN≤6.4MPa, faʻaaogaina mo le kelope valve, polo valve, ma isi.

9. Nitrided uamea

O le vasega masani faʻaaogaina o le uamea faʻamaʻi o le 38CrMoAlA, lea e lelei le faʻafefeteina ma le maoaʻe pe a uma togafitiga carburizing. E masani ona faʻaaogaina i le alatoto faitotoa nofoaga eletise ma le vevela t≤540℃ ma le mamafa PN≤10MPa.

10. Boronizing

Boronizing tuusa'o fa'agasolo le fa'amaufa'ailoga mai mea o le valve tino po'o le tino tisiketi, ona fa'atinoina lea o le togafitiga o le boronizing, o le fa'amaufa'ailoga e lelei le ofuina. Fa'aoga ile alavai fa'ato'ilalo ile nofoaga eletise.
