Njengevalvu esetyenziswa kakhulu, ivalvu yebhola ikwayeyona valvu isetyenziswa kakhulu. Iindidi ezahlukeneyo zeentlobo ziyahlangabezana nokusetyenziswa ngumsebenzisi kwiimeko ezahlukeneyo eziphakathi, kwiindawo ezahlukeneyo zobushushu kunye neemfuno ezahlukeneyo zenkqubo kwinkqubo yokwenyani. Oku kulandelayo kwazisa iimpawu zeevalvu zebhola eziqhelekileyo ezininzi ezifana neevalvu zebhola ezidadayo, iivalvu zebhola ezizinzileyo, iivalvu zesiqingatha sebhola ezingaqhelekanga, iivalvu zebhola ezimile okwe-V kunye neevalvu zebhola ezine-fluorine.
Ngokwesakhiwo kunye nomsebenzi, ingahlulwahlulwa ibe:
1. Kukho iintlobo ezahlukeneyo zeevalvu zebhola. Zithini iivalvu zebhola ezidadayo: Iivalvu zebhola ezidadayo zisetyenziswa njengezitywini kwaye ibhola iyadada. Isebenzisa uxinzelelo lwesixhobo ukutyhala ibhola ukuhambisa umgama kunye nokucinezela isihlalo sevalvu elastiki ukuze kufezekiswe isiphumo sokutywina. Olu hlobo lwevalvu edadayo lunokumelana okukhulu kokuvula kwaye lufanelekile kuphela kwiipayipi kunye nezixhobo ezine-caliber ye-DN "200 kunye noxinzelelo lwe-PN "100. Ukuba ububanzi bebhola bukhulu kakhulu, buya kugoba umzimba wevalvu kwaye bungaphumeleli phantsi koxinzelelo lwesixhobo; ukuba uxinzelelo luphezulu kakhulu, ivalvu yebhola iya kucinezelwa kwaye i-elastic kwaye isihlalo sevalvu elastiki siya konakala ngonaphakade, nto leyo enokonakalisa isitywini kwaye ichaphazele ubomi bevalvu yebhola.
2. Ivalvu yebhola ezinzileyo iqiniswe ziziqu ezibini eziphezulu nezisezantsi. Isihlalo sevalvu sixhotyiswe ngentwasahlobo yamagqabi okanye intwasahlobo ejikelezayo esisilinda. Xa ixhotyiswe, intwasahlobo yesihlalo sevalvu iyacinezelwa ukuvelisa amandla okuqinisa kwangaphambili ukuze kufunyanwe uphawu lokuqala lwevalvu. Uxinzelelo lutyhala ivalvu ngexesha lokusetyenziswa. Isihlalo siya ebholeni ukuze kufunyanwe uphawu. Ngenxa yokuba ibhola ayishukumi, ibizwa ngokuba yivalvu yebhola ezinzileyo. Olu hlobo lokuqinisa luthembeke ngakumbi kunevalvu zebhola ezidadayo ngenxa yokuthembeka kwayo kokuvala. Ingasetyenziswa kuluhlu olubanzi, kungekuphela nje kwiidayamitha ezincinci ezinoxinzelelo oluphantsi, kodwa nakwiidayamitha ezinkulu ezinoxinzelelo oluphezulu. Kodwa ulwakhiwo lwayo luyinkimbinkimbi ngakumbi.
Ixabiso liphezulu, xa ukhetha, kufuneka ukhethe ngokweemfuno zokwenyani.
3. Ivalvu ye-hemispherical eccentric. Olu hlobo lwevalvu yebhola lusebenzisa isakhiwo esingaqhelekanga. Umgaqo wesakhiwo ufana nowevalvu yebhabhathane enezingqimba ezintathu engaqhelekanga eqinileyo etywiniweyo. Isihlalo sevalvu kunye nebhola azigugi kwaye zinomsebenzi wokutywina oqinileyo. Ibhola yi-1/4 kuphela yevalvu yebhola eqhelekileyo. Inomphezulu ogobileyo, ubunzima obulula kunye nexabiso eliphantsi. Oku kunempembelelo yokucheba kwaye kungasetyenziswa kumbhobho ophakathi oqulethe imicu emide ngaphandle kokuxinana.
4. I-flange yevalvu yebhola yokugquma ubushushu ineenkcukacha ezi-1 ukuya kwezi-2 ezinkulu kunevalvu yebhola yeflange eqhelekileyo. Isebenzisa umzimba wevalvu odibeneyo kunye noyilo lwebhola olufakwe ecaleni. Ijakethi yesinyithi idityaniswe phakathi kweeflanges ezandisiweyo ngaphandle komzimba wevalvu. Ikwabizwa ngokuba yivalvu yebhola egquma ubushushu. Ii-interfaces zejakethi zifakelwe kumacala omabini omzimba wevalvu, ezinokutshizwa ngomphunga okanye enye igesi eshushu kakhulu ukuthintela ukuba i-medium iqine okanye i-crystallization kubushushu begumbi. Iivalvu zebhola zokugquma ubushushu zisetyenziswa kakhulu kwiipayipi kunye nezixhobo ezilula ukuzinyibilikisa kwaye zifuna ukugquma ubushushu kwiinkqubo zepetroleum, chemical, metallurgical, kunye neyeza.
5. Ivalvu yebhola enomfanekiso we-V yivalvu yebhola elawulayo. Umngxuma wokuhamba kwebhola wahlukile kakhulu kumngxuma othe tye wevalvu yebhola eqhelekileyo. Ibhola inesakhiwo esinomfanekiso we-V kwaye idla ngokuthatha isakhiwo esizinzileyo esineziqu ezibini eziphezulu nezisezantsi.
6. Ivalvu yebhola ene-fluorine isetyenziswa rhoqo kwiipayipi zezixhobo eziphakathi ezinobushushu obuphantsi kunye nezomeleleyo. Olu hlobo lwevalvu yebhola lufakwe iiplastiki zobunjineli ezimelana nokugqwala ezifana ne-PFA okanye i-FEP kuzo zonke iindawo zetshaneli yokuhamba ezidibana ne-medium. Ingathatha indawo yentsimbi engagqwaliyo neHastelloy ebizayo phantsi kwemeko yokuba ingadluli kubushushu benkonzo yerabha ye-fluorine kwipayipi yoxinzelelo oluphantsi. , i-Monel alloy, i-No. 20 alloy, isombulula ingxaki yokuthutha imidiya egqwala kakhulu kwiipayipi ze-petrochemical kunye neekhemikhali.

INortech ngomnye wabavelisi beevalvu zoshishino abaphambili eTshayina abanesiqinisekiso somgangatho se-ISO9001.

Iimveliso eziphambili:Ivalvu yebhabhathane,Ivalvu yeBhola,Ivalvu yeSango,Jonga iValve,IGlobe Vavlve,Ii-Y-Strainers,Isixhobo sombane,Ii-Acurators ze-Pneumatic.
