uamea uamea si'isi'i alavai siaki H71W/u'amea u'amea tasi-ala valve/wafer si'isi'i alavai le toe fo'ifa'aaogaina le tele o le fausaga pupuu ma le mamanu tisiki tasi.Pe a faatusatusa i le masani siaki siaki valve, o lenei faasologa o valves e leai se Leakage fafo, e mafai ona faapipiiina i so o se tulaga, faatinoga lelei faamauga, vibration laina maualalo, pa'ū maualalo mamafa ma leai nofoa mama ofu lelei.O lana galuega autu o le mamafa o le samala vai e laʻititi tele, o le valve flap stroke e puupuu, o le valve flap e mama, faʻatasi ai ma le puna fesoasoani e tapunia, ma le saoasaoa o le tapuni valve e vave tele.O le fausaga e puupuu le umi, laʻititi i le lapopoa, ma le mama i le mamafa, lea e aumaia ai le faʻaogaina tele i le faʻapipiʻiina o valve, felauaiga, teuina ma le faʻaogaina o paipa.
Fa'avae galue:
O lo'o tu'u le fa'alava o le valve i le ogatotonu e fa'agasolo i luga ma lalo.Ona o le tapuni pupuu pupuu o le valve fugalaʻau ma le tautotogo uta, o le tapuni saoasaoa e vave, lea e mafai ona faʻaitiitia ai le faʻaalia o le samala vai.O le oloa ei ai uiga o le laʻititi laʻititi, mama mama, gaioiga maaleale, faʻamaufaʻailoga faʻalagolago, ma faʻapipiʻi faigofie.E fetaui lelei mo taimi e faʻatapulaʻa ai avanoa faʻapipiʻi.
Vaega:
1. E tapuni vave le tapuni o le valve ma e laʻititi le mamafa o le samala vai.
2. E puupuu lona fausaga, laʻititi laʻititi ma mama mama.
3. E le faʻalavelaveina le ala tafe, e laʻititi le tetee o le vai;o le gaioiga e maaleale, ma o le faʻamaufaʻailoga e lelei.
4. Ona o le vave tapunia, e mafai ona taofia le ala mai le tafe i tua ma aveese le samala vai.
5. Faʻafaigofie ona faʻapipiʻi, e mafai ona faʻapipiʻi i luga o paipa i itu uma e lua ma faʻasaga.
6. O le ipu valve faʻaaogaina le mamanu o le faʻaopoopoina o puna torsion e lua i luga o le ipu mating, lea e mafai ona faʻapipiʻi vave ai le ipu valve.
Avanoa o le talosaga:
E fetaui lelei mo laina paipa eseese ma le mamafa PN1.6Mpa～42.0Mpa, Vasega150～2500LB;tamimita fa'aigoa DN15~1200mm, PNS1/2~48″;vevela galue: -196 ~ 540 ℃, faʻaaoga e puipuia ai le toe foʻi.Valve.O mea a le tino o: carbon steel, stainless steel, etc., lea e mafai ona faʻaaogaina mo vai, ausa, kesi, suauʻu, faʻasalalauga acid, ma isi.
