Iimpawu zeValvezizinto ezibalulekileyo kwizicwangciso zobunjineli, ingakumbi kwiimizobo yemibhobho kunye nezixhobo (I-P&IDPhakathi kwezi mpawu,uphawu lwevalvu yebhabhathaneIvelele ngoyilo lwayo olwahlukileyo kunye nokusetyenziswa kwayo ngokubanzi kwezoshishino. Eli nqaku liphonononga ukubaluleka kophawu lwevalvu yebhabhathane, liluthelekisa nezinye iimpawu zevalvu ezifanauphawu lwevalvu engabuyisiyo, kwaye igxininisa indimaAbavelisi kunye nababoneleli ngeevalvu zebhabhathane ezisekwe eTshayinaekunikezeleni izisombululo ezikumgangatho ophezulu kukhuphiswanoamaxabiso evalvu yebhabhathane.
Yintoni uphawu lweValve yeButterfly
Iuphawu lwevalvu yebhabhathaneyimifanekiso elula esetyenziswa kwimizobo yobunjineli ukubonisa ubukho bevalvu yebhabhathane kwinkqubo yepayipi. Ngokwesiqhelo inemigca emibini ethe nkqo (emele idiski) edibana nomgca othe tye (umbhobho), okwenza "ibhabhathane"imilo." Olu phawu lunceda iinjineli kunye neengcali ukuba zichonge ngokukhawuleza iintlobo zeevalvu ngexesha loyilo lwenkqubo, ukugcinwa, okanye ukusombulula iingxaki.
Iivalvu zebhabhathanezithandwa ngenxa yoyilo lwazo oluncinci, ukusebenza ngokukhawuleza, kunye nokusebenza kakuhle kweendleko. Zilawula ukuhamba kwamanzi ngokujikeleza idiski ngama-90 degrees, nto leyo ezenza zilungele imibhobho emikhulu kumashishini afana nokucoca amanzi, ioyile negesi, kunye neenkqubo ze-HVAC.
Iimpawu zeValve eziqhelekileyo: iValve yeButterfly vs. iValve engabuyiyo
Ukuqonda iimpawu zevalvu kuqinisekisa ukuchaneka koyilo lwenkqubo. Nantsi uthelekiso lweempawu ezimbini eziphambili:
1. Uphawu lweValve yeBhabhathane
– Imele ivalvu ejikelezayo yekota enediski ejikelezayo.
– Izotywe njengomgca othe nkqo odibana nomgca wepayipi othe tye.
– Idla ngokuphawulwa ngolu hlobo “BV"okanye ezinye izichazi-magama ukuze kucace."
2. Uphawu lweValve engabuyiyo (Jonga iValve)
– Yenzelwe ukuvumela ukuhambahamba kwicala elinye kuphela.
– Iboniswe njengentloko yotolo ekhomba kwicala elivumelekileyo lokuhamba, idla ngokuba nomgca othe tyaba okanye ukuvalwa okugobileyo.
Nangona iivalvu zebhabhathane zilawula indlela yokuhamba kunye nomthamo, iivalvu ezingabuyiyo zithintela ukubuya kwamanzi. Zombini ezi mpawu zibalulekile ekugcineni ukusebenza kakuhle kwenkqubo kunye nokhuseleko.
Kutheni Umthombo Uvela Kwincwadi EthembekileyoUmvelisi weValve yeButterflyeTshayina
I-China ivele njengesikhungo sehlabathi sokuvelisa iivalvu zoshishino, inika:
- Izisombululo Ezisebenza Ngexabiso Eliphantsi: Ukhuphiswanoamaxabiso evalvu yebhabhathanengenxa yeenkqubo zokuvelisa ezilungelelanisiweyo kunye noqoqosho oluphezulu.
- Ubuchwepheshe obuPhambili: Ukukhokelaababoneleli ngeevalvu zebhabhathaneeTshayina sebenzisa imigca yemveliso ezenzekelayo kwaye ulandela imigangatho yamazwe ngamazwe (ISO, API, CE).
- Ukwenziwa ngokwezifiso: Abavelisi banikezela ngoyilo olulungiselelweyo lwemilinganiselo ethile yoxinzelelo, izixhobo (isinyithi esenziwe ngentsimbi, intsimbi engatyiwayo), kunye neendlela zokusebenzisa (ngesandla, ngomoya, ngombane).
- Ubuchule bokuthumela ngaphandle kwihlabathi liphela: Ababoneleli baseTshayina babonelela abathengi kwihlabathi liphela, beqinisekisa ukuhanjiswa ngexesha elifanelekileyo kunye nokuthobela iziqinisekiso zengingqi.
Izinto Ezichaphazela Ixabiso leValve yeButterfly
Iixabiso levalvu yebhabhathaneiyahluka ngokusekelwe kwi:
- Izinto eziphathekayoIivalvu zentsimbi engatyiwayo zibiza ngaphezulu kunentsimbi ephosiweyo kodwa zinokumelana nokugqwala okuphezulu.
- Ubungakanani kunye novavanyo loxinzeleloIivalvu ezinkulu (umz., ububanzi obuziisentimitha ezingama-48) okanye iimodeli ezinoxinzelelo oluphezulu zifuna ulwakhiwo oluqinileyo, nto leyo enyusa iindleko.
- Uhlobo Lokusebenza: Iivalvu ezizenzekelayo ezinee-actuator zibiza kakhulu kunezo zenziwe ngesandla.
- Indawo yoMboneleli: Ukufunyanwa ngqo kwiAbathengisi bevalvu yebhabhathane eTshayinakudla ngokunciphisa iindleko xa kuthelekiswa nabalamli.
Ukukhetha umthengisi weValve yeButterfly efanelekileyo
Xa ukhethaumthengisi wevalvu yebhabhathane, beka phambili:
1. Iziqinisekiso: Qinisekisa ukuba iyathotyelwa imigangatho yoshishino.
2. Amava: Khetha abavelisi abanembali eqinisekisiweyo kwicandelo lakho.
3. Inkxaso Emva Kokuthengisa: Khangela iwaranti, uncedo lobuchwephesha, kunye nokufumaneka kwezixhobo ezingasetyenziswanga.
Ababoneleli abaninzi baseTshayina, abafanaUmvelisi weValve ye-NSW, dibanisa ukufikeleleka kunye nokuthembeka, nto leyo ebenza babe ngamaqabane akhethwayo kwiiprojekthi zehlabathi.
Isiphelo
Iuphawu lwevalvu yebhabhathanelilungu elibalulekileyo kwimizobo ye-P&ID, ebonisa indima yevalvu kulawulo lokuhamba kwamanzi. Kumashishini afuna izisombululo ezihlala ixesha elide nezingabizi kakhulu, ukusebenzisana nomvelisi weevalvu zebhabhathane odumileyo eTshayina** kuqinisekisa ukufikelela kwiimveliso ezikumgangatho ophezulu ngamaxabiso akhuphisanayo. Nokuba ufuna iivalvu ezisemgangathweni okanye uyilo olulungiselelwe wena, uthotho lokubonelela oluqinileyo lwaseTshayina kunye nobuchule bobuchwephesha kwenza ukuba ibe lolona khetho luphezulu lokufumana iivalvu zoshishino.
Ngokuqonda iimpawu zeevalvu nokusebenzisana nababoneleli abathembekileyo, amashishini angenza ngcono iinkqubo zawo ukuze zisebenze, zikhuseleke, kwaye zibe nexabiso lexesha elide.
