Ziya zisanda iivalvu zaseTshayina zithunyelwa kumazwe ahlukeneyo kwihlabathi liphela, kwaye ke uninzi lwabathengi bangaphandle abaqondi ukubaluleka kwenombolo yevalvu yaseTshayina, namhlanje siya kukuthatha ekuqondeni okuthile, sinethemba lokunceda abathengi bethu.
E-China, iintlobo zeevalvu kunye nezixhobo ngakumbi nangakumbi, ukulungiswa kweemodeli zevalve kunzima ngakumbi nangakumbi;Iimodeli zevalvu kufuneka zibonise uhlobo lwesivalo, imowudi yokuqhuba, uhlobo loqhagamshelo, iimpawu zesakhiwo, uxinzelelo lwegama, imathiriyeli yomphezulu wokutywina, imathiriyeli yomzimba wevalvu kunye nezinye izinto.Imodeli yomgangatho wevalve yoyilo lwevalve, ukhetho, ukuhanjiswa, ibonelela ngendlela efanelekileyo yokuvumela abasebenzisi ukuba bajonge i-nameplate baya kukwazi ubume bohlobo oluthile lwevalve, izixhobo kunye neempawu.
Ngoku makhe sithathe umzekelo:

Iyunithi 6, imodeli yoxinzelelo lweValve
Amaxabiso oxinzelelo lwegama achazwa ngokuthe ngqo kwii-numerals zesi-Arabhu (__MPa) Ixabiso le-MPa liphindwe ka-10 inani leekhilogram.Phakathi kweeyunithi zesihlanu kunye nesithandathu, ibha enqamlekileyo isetyenziselwa ukudibanisa.Emva kwebar ethe tye, ibonakaliswe kwixabiso eliphantsi loxinzelelo lweyunithi yesithandathu.Into ebizwa ngokuba yi-nominal pressure luxinzelelo olunokuthi ivalve ikwazi ukumelana nayo.

Indima yokuchongwa kwevalvu
Ukuchongwa kwevalve ngokungabikho kwemizobo yevalvu, ukulahleka kweplate yegama kunye neenxalenye zevalvu azigqitywanga, ukusetyenziswa okuchanekileyo kweevalvu, iinxalenye zevalve ye-welding, ukulungiswa kunye nokutshintshwa kweendawo zevalve kubalulekile.Ngoku ukuphawulwa kwevalve, ukuchongwa kwezinto kunye nokuchongwa kwevalve kuchazwe ngezantsi:
Ukusetyenziswa "kolwazi olusisiseko lwesivalo" ulwazi olufundiweyo, ngokweplate yegama kunye nelogo ekwivalvu kunye nevalve kumbala wepeyinti.Unokwazi ukuchonga ngokuthe ngqo udidi lwe-valve, ifom yesakhiwo, izinto eziphathekayo, i-diameter yegama, uxinzelelo lwegama (okanye uxinzelelo lokusebenza), imidiya eguquguqukayo, ubushushu kunye nolwalathiso lokuvala.
1.I-nameplate igxininiswe kumzimba wevalvu okanye ivili lesandla.Idatha kwi-nameplate iphelele ngakumbi kwaye ibonisa iimpawu ezisisiseko zevalve.Ngokomenzi kwi-nameplate, kumenzi wevalvu enxibe imizobo yamalungu kunye nolwazi;ngokomhla wefektri yereferensi yokulungiswa;ngokwenameplate ibonelela ngemiqathango yokusetyenziswa, ukumisela ukutshintshwa kweegaskets, imathiriyeli yepleyiti yevalve kunye neefom kwakunye nokumisela ukutshintshwa kwezinye iindawo zevalvu yento.
2.Ukumakishwa kusetyenziswa ukuphosa, ukubhala kunye nezinye iindlela kumzimba wevalve ephawula ivalve yegama loxinzelelo, uxinzelelo lokusebenza, i-caliber yegama kunye ne-medium flow direction.
3.I-Valve kukho uhlobo lokumakisha imiyalelo evulekileyo evulekileyo, ivule isikali somlawuli okanye ibonise ukuvulwa nokuvalwa kotolo.Iivalve ze-Throttle, iivalve zesango ezimnyama zibhalwe ngemiyalelo yokutshintsha kwincam engaphezulu ye-handwheel ibhalwe ngotolo olukhomba kwicala lokuvala.
