Abavelisi beValve yeBhola yaseTshayina: Imibuzo yakho ephambili iyaphendulwa

Ukukhetha ivalvu yebhola efanelekileyo kubandakanya ukuqonda umahluko obalulekileyo phakathiabavelisi, ababoneleli, kunye nabasasaziEsi sikhokelo siphendula imibuzo ebalulekileyo ukukunceda wenze ukhetho olunolwazi malunga nokuthengwa kweevalvu zemizi-mveliso.

Abavelisi vs. Ababoneleli: Yintoni umahluko

A umenzi wevalvu yebholaUngumnikazi wezakhiwo zemveliso, ejonga yonke into ukusuka kuyilo ukuya kulawulo lomgangatho. Ababoneleli okanye abasasazi bathengisa kwakhona iimveliso zomntu wesithathu. Ngelixa ababoneleli benikezela ngokuhanjiswa ngokukhawuleza, abavelisi banikezela:

- Amaxabiso aphantsingokuphelisa abantu abaphakathi

- Izisombululo ezenziwe ngokwezifisokwizicelo ezizodwa

- Ulawulo oluqinileyo lomgangathokunye nobuchule bobuchwephesha

Kutheni kufuneka ube ngumlingani ngqo nabavelisi bevalvu yebhola

1. Ulawulo Lomgangatho Ophezulu: Imveliso yangaphakathi iqinisekisa ukuthotyelwa kwemigangatho ye-ISO/API.

2. Ukusebenza kakuhle kweendleko: Amaxabiso ngqo agcina i-20-40% xa kuthelekiswa neekowuteshini zomsasazi.

3. Ukwenziwa ngokwezifiso: Yila iivalvu ezilungele uxinzelelo oluthile, ubushushu, okanye iimfuno zezinto eziphathekayo.

4. Uxhaso lobuchwepheshe: Isikhokelo seengcali malunga nokukhetha nokugcina iivalvu.

Abavelisi beValve yeBhola yaseTshayina ngokuchasene nabaKhuphisani beHlabathi

I-China ilawula imveliso yeevalvu zoshishino ngeenzuzo ezinomtsalane:

- Ukusebenza kakuhle kweendleko: Amaxabiso akhuphisanayo ngaphandle kokunciphisa umgangatho.

- UkukhulaIifektri ezinkulu zijongana nee-odolo ezinkulu ngokukhawuleza.

- Iziqinisekiso: Abavelisi abaphambili bathobela imigangatho ye-ANSI, DIN, kunye ne-API.

- Ubuchwepheshe: Utyalo-mali lwemveliso ezenzekelayo kunye notyalo-mali lwe-R&D luqinisekisa izisombululo ezisemgangathweni.

Nangona iimpawu zaseYurophu/zaseMntla Melika zigqwesa kwiivalvu ezichanekileyo kakhulu,Abavelisi baseTshayinazibonelela ngezakhono ezibanzi kwiizicelo ezininzi zoshishino ezingconoamanqaku exabiso.

Izizathu ezi-4 zokukhetha abavelisi beValve yeBhola yaseTshayina

1. Amaxabiso Anzima: Gcina i-20-40% ngaphezu kwezinye iindlela zaseNtshona.

2. Iziseko zoPhuhliso eziPhambiliIifektri zanamhlanje ziqinisekisa imveliso ehambelanayo kunye nokukhula kwayo.

3. Ukuthobela imithetho kwihlabathi liphela: Ubuchule kwimigangatho yamazwe ngamazwe yokudibanisa okungenamthungo.

4. Ubuchule bokuthumela ngaphandle: Uthutho olulungelelanisiweyo kumazwe angaphezu kwe-100.

Indlela yokukhetha umenzi othembekileyo waseTshayina

Landela olu qinisekiso lunezinyathelo ezi-6:

1. Jonga iziqinisekiso: Qinisekisa ukuthobela i-ISO, i-API 6D, okanye i-CE.

2. Ubungakanani bokuVeliswa koPhicotho-zincwadi: Qinisekisa ukuba uyakwazi ukuphatha ivolumu yeodolo yakho.

3. Cela iisampuli: Izixhobo zovavanyo, umlinganiselo woxinzelelo, kunye nokuqina.

4. Thelekisa iingcaphuno: Beka ixabiso (umgangatho + inkonzo) phambili kunexabiso eliphantsi.

5. Uhlolo lweeNgqinisekisoJonga izifundo zeemeko ezivela kubathengi behlabathi.

6. Qinisekisa emva kokuthengisa: Qinisekisa inkxaso yobugcisa ephendulayo kunye nokugubungela iwaranti.

Into ephambili yokuthatha

Ukusebenzisana ngokuthe ngqo neumenzi wevalvu yebhola—ingakumbi eTshayina—inika ulawulo olufanelekileyo kumgangatho, iindleko, kunye nokwenza ngokwezifiso. Umxube wabo weiifektri eziphambili, ukusetyenziswa kakuhle kweendleko, kunye nobuchule bobuchwephesha kuzenza zibe zilungele iiprojekthi zoshishino ezifuna ukuthembeka kunye nexabiso.

Umthengisi weValve yeBhola ocetyiswayo

Umthengisi weevalvu zebhola zobungcali kunye nomzi-mveliso – Umvelisi weValve yeNSW

I-NSW yenye yezonaIimpawu zeValve zeBhola ezili-10 eziphezulu eTshayina.Banemizi-mveliso yanamhlanje kunye nezixhobo eziphambili zokucubungula iivalvu. Baziingcali ekuveliseni iintlobo ezahlukeneyo zeevalvu zebhola kunye neevalvu zebhola ezenziwe ngezinto ezahlukeneyo, ezifanaiivalvu zebhola ezifakwe kwi-trunnion, iivalvu zebhola ezidadayo, iivalvu zebhola zokungena eziphezulu, iivalvu zebhola zentsimbi yekhabhoni, iivalvu zebhola zentsimbi engatyiwayo, iivalvu zebhola zentsimbi ezimbini, iivalvu zebhola ze-cryogenic, iivalvu zebhola ezinobushushu obuphezulu, njl.

I-NSW ilandela ngokungqongqo imigangatho yoyilo ye-API6D kunye ne-ISO14313 kunye nemigangatho yovavanyo ye-API 6D kunye ne-API 598. Kwangaxeshanye, i-NSW ikwaphumelele nezinye iimvavanyo zamazwe ngamazwe ezifana ne-ISO 15848-1, i-ISO 15848-2, i-API 607, i-API 6FA kunye nezinye iziqinisekiso.
