Fa'amatalaga pu'upu'u o le fa'atinoga o le masini eletise fa'ato'a liliu (ituaiga Z)

Fa'amatalaga pu'upu'u o le fa'atinoga o le masini eletise e tele-liliu (ituaiga Z) O se masini mo le fa'atonutonuina o le tafe, mamafa, ma le fa'atonuga o le tafe o se vai (suavai, kesi, kesi-suavai, po'o le fa'afefiloi malō-vai). E taʻua o le "valve. E masani ona aofia ai le valve body, valve cover, nofoa, tatala ma tapuni vaega, faʻaogaina o masini, faʻamaufaʻailoga ma faʻamau. , swinging po'o le liliu e sui le tele o le vaega o le tafe e ausia *** e faʻaaogaina i fale gaosi oloa ma faʻatoʻaga ma mea faigaluega i aso taʻitasi na faia i Saina Aʻo leʻi oʻo i le 2000 TLM, o paipa ofe ma alalaupapa laupapa sa faʻaaogaina i paipa vai. i Saina mulimuli ane, na faʻaaogaina vaivai i alavai faʻafefeteina, faʻaoga siaki siaki i le faʻafefeteina, ma faʻaoga paipa faʻapipiʻi ma faʻaogaina i le vaʻaia masima e suʻe vai masima Faʻatasi ai ma le atinaʻeina o tekinolosi faʻafefeteina ma masini eletise. fa'alava apamemea ma ta'ita'i na fa'aalia i Europa I le 1681, na fa'aalia ai le va'a o le samala o le Butterfly i le 1769. Ona o'o mai ai lea o le va'a fa'ase'e i le 1840, o lo'o i ai ni fa'a'au fa'a'au fa'ama'i fa'alava. Mulimuli ane, ona o le atinaʻeina o le eletise, suauu, vailaʻau vailaʻau ma fale fau vaa, o le faʻaaogaina o mea fou fou, o ituaiga uma o valve ua fananau mai ma faʻavavevave, o le gaosiga o valve ua faasolosolo malie ona avea ma vaega taua o le alamanuia masini. Valve e maua lautele. E tusa ai ma le faʻaaogaina o galuega, e mafai ona vaevaeina i: ① poloka valve. Fa'aaogaina e tipi ese pe tu'u i totonu o le ala, e aofia ai le faitotoa valve, globe valve, diaphragm valve, plug valve, polo valve, butterfly valve, ma isi. ② Control valve. Mo le faʻatonutonuina o le tafe ma le mamafa o le vai, o vaʻa na faia i Saina e aofia ai vaʻa faʻatonutonu, vaʻa faʻafefe, faʻaitiitiga faʻaitiitia o le mamafa ma isi. ③ Siaki valve. Fa'aaoga e taofi ai le tafe i tua o le vai. (4) alatoto suisui. Fa'aoga mo le tu'uina atu, tu'u'ese'ese ma fa'afefiloi vai, e aofia ai va'a fa'ase'e, alavai fa'atele, mailei, ma isi mea. ⑤ Valau saogalemu. Faʻaaogaina mo le puipuia o le saogalemu o le overpressure, puipuia le pusa, vaʻa mamafa poʻo le faʻaleagaina o paipa, ma isi. E tusa ai ma le vevela galue e mafai ona vaevaeina i valve vevela maualuga, valve vevela vevela, valve vevela masani, valve vevela maualalo; E tusa ai ma le auala avetaʻavale, e mafai ona vaevaeina i valve tusi lesona, valve eletise, valve pneumatic, valve hydraulic, ma isi. E tusa ai ma uiga o le matagaluega faʻaoga, e mafai ona vaevaeina i le gataifale valve, vai faʻavevela valve, eletise eletise ma isi. O ta'iala autu o le valve o le mamafa galue, vevela galue ma le caliber. Vave eseese o pipelines alamanuia, e masani ona faaaogaina nominal pressure pN (o le mamafa o galuega mamafa faatagaina e tauave i lalo o le vevela faamaoti) ma nominal diameter DN (nominal diameter o le tino valve ma le paipa sootaga pito) e fai ma faavae autu. O le valve e masani lava ona faʻamaufaʻailogaina, malosi, tulafono faatonutonu, faʻasalalauga, tatala ma tapuni faʻatinoga, e aofia ai le lua muamua e sili ona taua le faʻatinoina o valve uma. Ina ia faʻamautinoa le faʻamaufaʻailogaina ma le malosi o le valve, i le faʻaopoopoga i tulaga talafeagai e tatau ona tausisia le faʻatulagaina o mamanu talafeagai, faʻamautinoa le lelei o le faagasologa, ae tatau foi ona saʻo filifilia mea. Faʻamatalaga o le faʻatinoga o le tele-turn valve masini eletise (ituaiga Z) Tele-turn valve masini eletise e iai le atoatoaga o galuega, faʻalagolago i le faʻatinoga, faʻatonuga faʻaleleia, laʻititi laʻititi, mama mama, faigofie ona faʻaoga ma tausia, ma isi *** faʻaaogaina i le eletise eletise, metallurgy, petroleum, alamanuia kemikolo, fai pepa, togafitiga otaota ma isi matagaluega. Tele - liliu valve masini eletise, ua ta'ua o le ituaiga Z. E fetaui lelei mo le tele-turn valve eletise masini faʻatasi ma le saʻo saʻo, e taʻua o le ituaiga Z. E talafeagai mo le valve saʻo, e pei o le valve gate, globe valve, diaphragm valve, vai faitotoa, ma isi. Faʻaaogaina mo le tatalaina o le valve, tapunia poʻo le fetuunaiga, o le alatoto e ausia ai le pulea mamao, pulea tutotonu ma le pulea otometi o le masini avetaavale taua. Tele - liliu le masini eletise, masini ta'avale, ulu eletise, fa'ata'ita'iga fa'apipi'i fa'apipi'i fa'ata'ita'iga fa'apipi'i fa'apipi'i masini eletise eletise fa'aogaina le si'osi'omaga galue: 3.2.1 Ambient vevela: -20 + 60 ℃ (poloaiga fa'apitoa -60 + 80 ℃) 3.2.2 Va'aiga vevela : 90%(i le 25 ℃) 3.2.3 Tulaga lautele ma ituaiga fafo o loʻo faʻaaogaina i nofoaga e aunoa ma ni faʻasalalauga faʻafefe / pa ma faʻafefe; O oloa e fa'asa'o fa'alavelave o le D ⅰ ma le D ⅱ BT4, D ⅰ e talafeagai mo le fa'aogaina o foliga galue ole maina koale; D ⅱ BT4 faʻaaogaina i fale gaosimea, talafeagai mo le siʻosiʻomaga o ⅱ A, ⅱ B T1-T4 vaega o faʻafefiloi kasa feusuaʻiga. (Vaai GB3836.1 mo faʻamatalaga) 3.2.4 Puipuiga grade: IP55 mo fafo ma le pa-faʻaalia ituaiga (IP67 e mafai ona faʻapitoa). 3.3.5 Faʻasologa o galuega: 10 minute (30 minute e mafai ona faʻatulagaina). Tele-turn valve eletise masini (ituaiga Z) masini taʻavale, ulu eletise, masini eletise eletise, faʻaogaina o le valve, faʻataʻavale afi, faʻaogaina o le eletise eletise e tusa ai ma le faʻaogaina o le siosiomaga: Z o le ituaiga masani; ZW o fafo ituaiga; ZB e le mu; O le ZZ o le ituaiga tu'ufa'atasi; ZT o le ituaiga faʻatonutonu. E tusa ai ma le malosi o le gaosiga: ituaiga torque ma le tui. O le faʻatinoga o le oloa e faʻatatau i le JB / T8528-1997 "General type valve eletise manaʻoga faʻapitoa". O le faʻatinoga o le faʻataʻitaʻiga o ituaiga faʻataʻitaʻiga e ogatasi ma aiaiga o le GB3836.1-83 "Manaoga lautele mo mea faʻapolofesa eletise mo le siosiomaga faʻafeusuaiga", GB3836.2-83 "Meafaigaluega eletise faʻafefete mo feusuaiga Siosiomaga afi mumu Meafaigaluega D" ma le JB/T8529-1997 "Tulaga faʻainisinia mo afi afi eletise eletise".
