Valve fa'apipi'i mana'oga fa'aogaina alavai fa'atonuga lelei ma fa'amatalaga fa'apitoa

Valve o loʻo i totonu o le faʻaogaina o le vai, faʻaaogaina e pulea le itu o le vai, mamafa, masini tafe, o le faia lea o paipa ma meafaigaluega i totonu o le ala (vai, gas, paʻu) tafe pe taofi ma mafai ona pulea le tafe o le masini. Valve o le vaega pulea o le pipeline fluid conveying system, faʻaaogaina e sui ai le vaega o le ala ma le ala o le tafe o le itu, faʻatasi ai ma le faʻafefe, tipi-off, throttling, siaki, shunt poʻo le faʻafefe o le mamafa o le mamafa ma isi galuega. Valve mo le fa'atonutonuina o le vai e amata mai i alavai faigofie o le kelope e o'o atu i mea e fa'aaogaina i faiga fa'aototometi lavelave, fa'atasi ai ma le tele o ituaiga ma fa'amatalaga, e amata mai i lapopo'a fa'apitoa mai alavai meafaifa'aili laiti e o'o atu ile 10m. E mafai ona faʻaaogaina e pulea le tafe o le vai, ausa, suauu, kesi, palapala, ituaiga uma o ala o faasalalauga corrosive, uʻamea vai ma vai leitio ma isi ituaiga o vai, valve galue mamafa e mafai ona mai le 0.0013mpa i le 1000MPa maualuga maualuga, vevela galue mafai c-270 ℃ i le 1430 ℃ maualuga vevela. E mafai ona faʻaogaina e le valve le faʻaogaina o le tele o faʻasalalauga, e pei o le tusi lesona, eletise, hydraulic, pneumatic, turbine, electromagnetic, electromagnetic hydraulic, eletise eletise, pneumatic, spur gear, bevel gear drive, ma isi; I le mamafa, vevela poʻo isi fomu i lalo o le gaioiga o faʻailoga faʻapitoa, gaioiga, e tusa ai ma le manaʻoga o le faʻapolopolo pe le faʻalagolago i faʻamaufaʻailoga mo le faigofie tatala pe tapuni, faʻalagolago i le taʻavale poʻo le masini otometi e tatalaina ai ma tapunia valve mo si'i, fa'ase'e, tu'u po'o le fe'avea'i, ina ia suia ai le tele o le taulaga ina ia iloa ai le galuega fa'atonutonu. Manaoga faʻapipiʻi 1, aʻo leʻi faʻapipiʻiina le valve, e tatau ona siaki ma le totoa le faʻataʻitaʻiga valve, faʻamatalaga ma le mamanu; 2, e tusa ai ma le valve faʻataʻitaʻiga ma faʻatonuga fale gaosi e siaki pe mafai ona faʻaogaina le valve i tulaga manaʻomia; 3. Pe a sii i luga le valve, e tatau ona nonoa le maea i le fesoʻotaʻiga flange o le tino valve ma le ufiufi valve, ae le nonoa i le uili lima poʻo le au, ina ia aua neʻi faʻaleagaina le au ma le uili lima; 4. Pe a faʻapipiʻi le valve i luga o le paipa faʻalava, e tatau ona tuʻu i luga le vaʻa o le valve, ma e le faʻatagaina ona faʻapipiʻi i lalo; 5, pe a faʻapipiʻi le valve, e le tatau ona faʻaogaina le faiga faʻafesoʻotaʻi paʻu faʻamalosi, ina ia aua neʻi faʻaleagaina ona o le malosi le tutusa; 6, e le tatau ona faʻapipiʻiina le alatoto o le faitotoa i lalo o le eleele susu, ina ia aua neʻi oʻo i le ele. Fa'apotopotoga mana'oga vaega mama e tatau ona fa'amaufa'ailogaina mo le fa'apipi'iina. O mea e manaʻomia mo le faʻapipiʻiina e faʻapea: 1. E tatau ona mama le faleaoga faʻapipiʻi, poʻo le faʻatulagaina o nofoaga mama le tumau, e pei o le faʻatau fou o ie lanu lanu poʻo se ata palasitika, e puipuia ai le pefu mai le ulufale i le taimi o le faʻapipiʻiina. 2, e tatau i tagata faigaluega faʻapotopotoga ona ofuina ni ofu faigaluega mama mama, ofuina se pulou mama mama, lauulu e le mafai ona tafe, vae ofuina seevae mama, lima e fai totigilima palasitika, degreasing. 3, e tatau ona degreased meafaigaluega faʻapotopotoga aʻo leʻi faʻapotopotoga, ina ia mautinoa mama. Manaoga Talia O le taliaina e tusa ma le HG 20202-2000 Code mo le Fausiaina ma le Taliaina o le Degreasing Engineering. A'o le'i fa'apotopotoina, solo ia vaega ta'itasi i pepa faamama sa'o mama, filifili tulimanu mate o vaega, ma le pepa faamama e le suia le lanu e agava'a. 1, o le valve faʻataʻitaʻiga e tatau ona faʻaalia e tusa ai ma le NATIONAL tulaga manaʻomia numera. Afai o le tulaga tau atinaʻe, e tatau ona faʻaalia le faʻamatalaga talafeagai o le faʻataʻitaʻiga. 2, o le valve galue mamafa, manaʻoga ≥ paipa galue mamafa, e aunoa ma le afaina o le tau o le fale, o le valve e mafai ona tauaveina le mamafa e tatau ona sili atu nai lo le mamafa o paipa. 3, valve gaosiga tulaga, e tatau ona faʻamatalaina le faʻavae o le NATIONAL standard numera, pe a fai o le atinaʻe tulaga, e tatau ona faʻapipiʻi le konekarate faʻatau i le pepa pisinisi. Mo nisi faʻamatalaga, faʻamolemole faʻafesoʻotaʻi i: Faʻapipiʻiina manaʻoga o le valve Structure Tulaga lelei ma faʻamatalaga faʻapitoa o le eletise eletise eletise "Power station valve", e lauiloa foi o le valve station valve, e masani ona faʻaoga i le paipa o faiga eseese o nofoaga eletise, tipi ese. po'o feso'ota'i ala fa'asalalau paipa. Fa'aoga auala: vai, ausa ma isi mea e le pala. Pe a faatusatusa i isi oloa valve, o le eletise eletise o loʻo faʻaalia i le maualuga o le vevela ma le maualuga o le mamafa, faʻailoga faʻamaufaʻailoga faʻapitoa, o le maualuga o le mamafa, o le faʻalagolagoina o le faʻamaufaʻailoga. Ona o le faʻatinoga faʻapitoa, uiga faʻapitoa ma tulaga faigaluega, o le oloa na fausia ai uiga e le mafai ona suia isi oloa. O le nofoa o le valve ma le fa'amaufa'ailoga fa'amau e faia i le cobalt-based carbide plasma spray welding, fa'atasi ai ma le lelei o le abrasion resistance ma le abrasion resistance.
I. Fa'atomuaga pu'upu'u ole alavai nofoaga eletise
"Power station valve" ua lauiloa foi o le eletise eletise, e masani lava ona talafeagai mo nofoaga eletise vevela i faiga eseese o le paipa, tipi ese pe tuʻu i totonu o le paipa. Fa'aoga auala: vai, ausa ma isi mea e le pala. Pe a faatusatusa i isi oloa valve, o le eletise eletise o loʻo faʻaalia i le maualuga o le vevela ma le maualuga o le mamafa, faʻailoga faʻamaufaʻailoga faʻapitoa, o le maualuga o le mamafa, o le faʻalagolagoina o le faʻamaufaʻailoga. Ona o le faʻatinoga faʻapitoa, uiga faʻapitoa ma tulaga faigaluega, o le oloa na fausia ai uiga e le mafai ona suia isi oloa.
