Fa'aogaina o Valves Fa'amau Fa'ailoga Fa'alua Fa'ailoga Fa'amau i Metallurgy System

Fa'ailoga fa'amaufa'ailoga fa'ailoga fa'alua luae faasolosolo faʻaleleia mai le valve butterfly masani e faʻafetaui i tulaga faigaluega eseese (e pei o le vevela galue ma le mamafa galue).O loʻo i ai le lelei o le fausaga faigofie, faʻamaufaʻailoga faʻalagolago, tatala malamalama, ola umi o le auaunaga ma le tausiga lelei.I le taimi nei, faʻatasi ai ma le atinaʻeina o suiga tetele o le ogaumu faʻapipiʻi masini i totonu o Saina, faʻaogaina faʻamaufaʻailoga faʻamaufaʻailoga lua faʻamaufaʻailoga faʻamaufaʻailoga i le tuʻuina atu o le vai ma alavai, fale puipui afi, metallurgy ma isi faiga paipa.

Fa'avae Galuega:
I le talitonuga, o le valve butterfly masani e faʻamaufaʻailogaina e pei o fesoʻotaʻiga laina.Ae mo le tele-tulagau'amea fa'ailoga fa'alua fa'amaufa'ailoga fa'ailoga pepe, O le tulaga o le paʻu faʻamaufaʻailogaina e fausia ai se fusi mama lautele mai le laina muamua ona o le faʻalavelave lona lua (o le tulaga o le valve stem e alu i luga).O le umi lava o le faʻafesoʻotaʻi luga o le paga faʻamaufaʻailogaina o loʻo i totonu o lenei fusi mama, e mafai ona iloa le faʻamaufaʻailoga e aunoa ma se vaega faʻapipiʻi pe a tatalaina le tisiketi valve.
I le taimi o le tatalaina o le valve disc, o le fa'amaufa'ailogaina o le fa'amaufa'ailoga fa'afefete masani o lo'o fa'agaoioi i luga o le ala fa'ata'ita'i o le pasi o nofoa valve conical.Ma o loʻo i ai se faʻaliliuga faʻatusatusa i le va o paga faʻamaufaʻailoga.O lea la, e telē le malosi o le friction.Peitai, o le faaliliuga i le va o paga faamau o leu'amea fa'ailoga fa'alua fa'amaufa'ailoga fa'ailoga pepee matua itiiti lava.Ma o vaega ta'itasi o le fa'amaufa'ailoga fa'afeso'ota'i i luga e vave ona vavae'ese i luga o le tagent trajectory itu o le pasi nofoa valve conical.O le mea lea, e laʻititi laʻititi le faʻafefeteina, lea e faʻaitiitia ai le ofuina i le va o paga faʻamaufaʻailoga.

I le faiga metallurgy, o le lua eccentric faigata faamaufaailoga butterfly e masani ona faaaoga i le preheating faiga ma mago efuefu aveesea faiga o le ogaumu uʻamea uʻamea ma le tele nominal diameter, mamafa galuega mamafa, maualalo tatala & tapunia eseese mamafa ma maualuga vevela (200°C. ~ 350°C).

E pei o lelua fa'ailoga fa'amaufa'ailoga fa'ailoga pepepeo loʻo i ai se faʻamaufaʻailoga lelei tele, lautele o le vevela talafeagai, mamafa tele o galuega, faʻaofuofu teteʻe, teteʻe corrosion ma le ola tautua umi.O le mea lea, o ana matafaioi e pei o se ea mu ea tapuni-off valve, mu kasa tapuni-off valve, kesi totonu & fafo tapuni-off valve o le vevela faiga, kesi kasa totonu & fafo tapunia-off valve o le vevela exchanger faiga ma kesi tapunia. -off valve o le pefu fa'amamago faiga.
