Yintoni ivalve yokujonga

Kwilizwe leenkqubo ze-fluid i-fluid kunye neenkqubo zokwenza imibhobho, iiValves zidlala indima ebalulekileyo ekuqinisekiseni ukuhamba ngokukhuselekileyo nangokhuseleko lotywala kunye neegesi. Njengecandelo elibalulekileyo kwizicelo ezahlukeneyo zemizi-mveliso, ukuqonda ukuba yeyiphi ivali yokukhangela, iindidi zayo kunye nabavelisi banokunceda iinjineli kunye neengcali zokuthengwa kweengcali zenza izigqibo ezizizo. Eli nqaku liza kuqhuba ebubini leevalves, egxile kwiindidi zayo, imisebenzi kunye nabavelisi beVova, ngakumbi eTshayina.

Ukuqonda iivalva

Ivalve yokujonga, ebizwa ngokuba yiValve yendlela enye, sisixhobo esivumelekileyo esivumela amanzi ukuba ahambe kwicala elinye ngelixa ekhulisa ukubuyela umva. Oku kubalulekile kwizicelo ezininzi, ezinjengeenkqubo zokubonelela ngamanzi, unyango lotywala, kunye neenkqubo ezahlukeneyo zeshishini. Umsebenzi ophambili we-valve yokukhusela izixhobo kunye nokugcina ingqibelelo ngokuthintela ukuhamba okuguqukayo, okunokubangela ungcoliseko, ukonakala kwezixhobo, okanye ukungaphumeleli kwezixhobo.

Umgaqo oSebenzayo weValve

Umgaqo wokuSebenza weValve yokujonga kukusebenzisa umahluko woxinzelelo phakathi kwe-upstream kunye ne-downngream. Xa uxinzelelo kwicala le-inletty lingaphezulu koxinzelelo kwicala lokuphuma, ivalve iya kuvula kwaye ivumele ulwelo ukuba luhambe. Kwelinye icala, ukuba uxinzelelo kwicala lokuphuma luba lungaphezulu, ivalve iyakuvala kwaye ithintele i-backflow. Le ndlela ilula kodwa esebenzayo yenza ukuba i-valve ibonakale ibalulekile kwiinkqubo ezininzi.

Iindidi zeevali zokujonga

Zininzi iindidi zee valves, yenzelwe iZicelo ezithile kunye neemeko zokuhamba. Ezona ntlobo ziqhelekileyo zibandakanya:

1. I-wing wing valve

I-valve yokujonga i-swing yenye yezona ntlobo zisetyenzisiweyo. Inika i-disc disc eguqukayo kwi-hinge, ivumela amanzi ukuba ahambe kwicala elinye ngelixa evaliwe ukuba i-backfflow yenzeka. I-windows yokujonga i-valves ilungele izicelo eziphantsi eziphakathi kwaye isetyenziswa rhoqo kwiinkqubo zamanzi, iinkqubo ze-HVAC, kunye neenkqubo ezahlukeneyo zeshishini.

2. I-valt yeplate yeplate

I-Poveli ye-disc ephindwe kabini iqulathe iipleyiti ezimbini ezi-pivot kwi-axis eqhelekileyo. Oluyilo luvumela i-compact kunye nevalve elula ethe tye xa kuthelekiswa neValve yesiqhelo yokujonga. I-vals disc disc isebenza ikakhulu kwizicelo eziphezulu zokuhamba kwaye zihlala zisetyenziswa kwimibhobho, izityalo zamanzi, kunye nemveliso yeoyile negesi.

I-3. I-Stainess Syve ye-Steele

I-valves yentsimbi engenasitayile yenzelwe izicelo ezifuna ukumelana nokunganyangeki kunye nokuqina. Ezi valves zihlala zisetyenziswa ekuqhubelweni kwamachiza, ukutya kunye namashishini esikhuselo, kunye nezicelo zaselwandle. Ulwakhiwo lwensimbi olungahambelaniyo luqinisekisa ukuba ubomi benkonzo bakudala kunye nokuthenjwa okuphezulu, kuyenza ukuba kukhetho lweenjineli ezininzi.

Ukubaluleka kokukhetha i-valve efanelekileyo

Ukukhetha i-valve efanelekileyo yokujonga iValve kubaluleke kakhulu ekuqinisekiseni umgangatho kunye nokuthembeka kweeValves kwinkqubo yakho. Umenzi weValve oKhangelekayo uya kubonelela ngeemveliso ezihlangabezana nemigangatho kunye neenkcazo, ukuqinisekisa ukusebenza kakuhle kunye nokhuseleko.

Kutheni ukhetha umenzi weValve waseTshayina?

I-China iye yeyona ndawo iphambili yokwenza izinto ezahlukeneyo zemveliso yemizi-mveliso, kubandakanya i-valves. Ilizwe linoluhlu olubanzi lweendawo zokujonga iiVolve, zinika yonke into ukusuka kwi-swing jonga i-valves kwi-valves yeplate yepleyiti ezimbini kunye neevallo ze-stail. Nazi ezinye zeenzuzo zokukhetha umenzi weValve waseTshayina:

1. Isebenza kakuhle emalini: Abavelisi baseTshayina badla ngokubonelela ngamaxabiso okhuphiswano kuba iindleko zemveliso ziphantsi. Oku kunokubangela ukonga iindleko ezibalulekileyo kwiinkampani ezifuna ukuthenga i-valves yokuthenga nge-bulk.

2. Uluhlu lwemveliso eyahlukeneyo: Abathengisi baseTshayina Abathengisi beValve bahlala benikezela ngeentlobo ngeemveliso ezahlukeneyo, abavumela abathengi ukuba bafumane uhlobo oluthile lwevalve ethile ehlangabezana neemfuno zabo.

3. Ukuqinisekisa umgangatho: Abavelisi basesiTshayina banamathela kwimigangatho esemgangathweni yamanye amazwe ukuqinisekisa ukuba iimveliso zabo zinokuthenjwa kwaye ziqinile. Iziqinisekiso ezinje nge-ISO 9001 inokubonisa ukuzibophelela komenzi.

4. Imveliso entsha kunye netekhnoloji: Abavelisi baseTshayina bayandisa utyalomali lwabo kwiitekhnoloji zokwenza imveliso kunye neenkqubo zokuphucula uyilo lwemveliso kunye nokusebenza.

5. Ubukho behlabathi: Uninzi lwabathengisi beValve basungula imisebenzi yehlabathi, besenza iimveliso kunye neenkonzo zabo zifikeleleke kubathengi bamanye amazwe.

Ukuqwalaselwa okuphambili xa kuthengwa i-valves

Xa ifumana i-valves yokukhangela kubavelisi, ngakumbi e China, kukho iinkalo ezininzi eziphambili zokugcina engqondweni:

1. Imigangatho esemgangathweni

Qinisekisa ukuba umenzi unamathele kwimigangatho efanelekileyo kunye nokuqinisekiswa. Oku kubandakanya isiqinisekiso se-ISO, kunye nokuhambelana nemigangatho ethile yeshishini efana ne-API, i-ASME okanye i-ASTM.

I-2. Jonga i-velove yemveliso

Vavanya imveliso yemveliso yoMvelisi ukuqinisekisa ukuba banikezela ngohlobo oluthile lweValve oyifunayo, nokuba yivali yokujonga i-swing, ivuthulo lwe-disc ephindwe kabini okanye ivalve ye-disve.

I-3. Ukukhetha ngokwezifiso

Izicelo ezithile zinokufuna ivalve yesiqhelo. Jonga ukubona ukuba umenzi ubonelela ngokukhetha iziko lokufezekisa iimfuno zakho ezithile.

4. Ixesha lokukhokela kunye nokuhanjiswa

Cinga ngexesha lokukhokelwa komenzi kunye nokukwazi ukuhambisa. Ukuhanjiswa kwexesha elifanelekileyo kubalulekile ukugcina iprojekthi yakho kwishedyuli kwaye ukuphepha ukulibaziseka okuxabisekileyo.

I-5. Inkxaso yentengiso yasemva kwentengiso

Vavanya inqanaba lenkxaso yentengiso yasemva kokuba inikezelwe ngumenzi. Oku kunokubandakanya ulwazi lwewaranti, inkxaso yezobugcisa, kunye nofakelo kunye noncedo lolondolozo.

ukuququmbela

Kwisishwankathelo, ii-valves zexabiso zizinto ezibalulekileyo kwiinkqubo ezahlukeneyo ze-fluid, zibonelela ngendlela ethembekileyo yokuthintela ukubuyela umva nokuqinisekisa ukunyaniseka kwenkqubo. Ukuqonda iintlobo ezahlukeneyo zeValves, ezinje ngeValves, i-valves ephindwe kabini, kunye neeVali zeSoftware eziPhezulu, zibalulekile ekukhetheni imveliso efanelekileyo yesicelo sakho.

Xa ifumana i-valves yokujonga, ngakumbi kumvelisi waseTshayina, kubalulekile ukuba uqwalasele izinto ezinje ngemigangatho esemgangathweni, uluhlu lwemveliso, izithuba zokuthengisa, kunye nenkxaso yasemva kwentengiso. Ngokwenza isigqibo esinolwazi kwaye sisebenza ngomenzi weVovolo oludumileyo, unokuqinisekisa ukusebenza ngokukuko nokhuseleko lwenkqubo yakho.
