Yintoni iValve yentsimbi engagqwaliyo

A ivalvu yentsimbi engatyiwayoyivalvu eyenziwe ngentsimbi engagqwaliyo. Ingasetyenziselwa ukulawula ukuhamba kweentlobo ezahlukeneyo zolwelo, kuquka umoya, amanzi, umphunga, iindidi ezahlukeneyo zezinto ezibolayo, udaka, ioyile, iintsimbi ezingamanzi, kunye nezinto ezisebenzisa i-radioactive.

1. Isishwankathelo esiSiseko kunye neentlobo eziphambili zeevalvu zentsimbi engagqwaliyo

Inkcazo kunye neempawu eziphambili:

A ivalvu yentsimbi engatyiwayoyivalvu enezixhobo zayo eziphambili, ezifana nomzimba wevalvu kunye nesigqubuthelo sevalvu, ezenziwe ngentsimbi engagqwaliyo.

Luhlobo lwevalvu olungenamhlwa, olumelana nokugqwala, kwaye olunenkxwaleko entle.

Uluhlu loxinzelelo olusebenzayo lweevalvu zentsimbi engagqwaliyo lunokuqala kuxinzelelo oluphantsi kakhulu lwe-0.0013MPa ukuya kuxinzelelo oluphezulu kakhulu lwe-1000MPa, kwaye uluhlu lobushushu olufanelekileyo lunokuqala kubushushu obuphantsi kakhulu be--269℃ ukuya kubushushu obuphezulu be-1430℃. Ingalawula iintlobo ezahlukeneyo zolwelo, kubandakanya amanzi, umphunga, ioyile, igesi, i-slurry, izixhobo ezahlukeneyo zokubola, iintsimbi zolwelo, kunye nolwelo olune-radioactive.

• Ukumelana nobushushu obuphezulu: Intsimbi engatyiwayo inendawo yokunyibilika ephezulu kwaye inokumelana nokusetyenziswa kwiindawo ezinobushushu obuphezulu.
• Ukumelana Nokugqwala: Intsimbi engagqwaliyo ayinakugqwala kwaye inokumelana nokusetyenziswa kwezinto ezigqwala.
• Ukumelana okugqwesileyo koxinzelelo: Intsimbi engatyiwayo inamandla kwaye iqinile, nto leyo eyenza ukuba ikwazi ukumelana neendawo ezinoxinzelelo oluphezulu.

2. Uhlu lweeValve zeNtsimbi engaGciniyo:

Iivalvu zentsimbi engenasici ziza ngeentlobo ezahlukeneyo, kunye neentlobo eziqhelekileyo eziquka:

2.1. Uhlu ngokweValve Uhlobo:

• I-Valve yeSango leNtsimbi engaGciniyo
• I-Stainless Steel Globe Valve
• I-Stainless Steel Check Valve
• Ivalvu yeButterfly yentsimbi engagqwaliyo
• I-Stainless Ball Valve

Phakathi kwazo, iivalvu zebhola zentsimbi engagqwaliyo zivula kwaye zivale ngokukhawuleza ngokujikeleza isiseko sevalvu ngama-90 degrees. Ngokusekelwe kwisakhiwo sazo, zinokwahlulwahlulwa zibe ziintlobo ezidadayo, ezizinzileyo, nezizinzileyo.

2.2. Uhlulo ngokwezixhobo zeValve:

• Ivalvu yeCF8 (ivalvu engama-304)
• Ivalvu yeCF8M (ivalvu engama-316)
• Ivalvu yeCF3 (ivalvu ye-304L)
• Ivalvu yeCF3M (ivalvu ye-316L)

Ezinye izinto zeevalvu zentsimbi engagqwaliyo ziquka iivalvu ezingama-321, iivalvu ezingama-201, njl.

3. Yintoni iStainless Steel

Intsimbi engagqwaliyo ligama elithetha intsimbi engagqwaliyo nengagqwaliyo. Iintsimbi ezingagqwaliyo kwizixhobo ezibuthathaka ezifana nomoya, umphunga, namanzi, okanye ezo zineempawu ezingagqwaliyo, zibizwa ngokuba yintsimbi engagqwaliyo. Iintsimbi ezingagqwaliyo kwizixhobo zekhemikhali ezingagqwaliyo (ii-asidi, ii-alkali, iityuwa, njl.njl.) zibizwa ngokuba yintsimbi engagqwaliyo.

Iingcali zesinyithi ziye zaphuhlisa amanqanaba amaninzi amatsha entsimbi ngokongeza izinto ezifana neMo, Cu, Nb, kunye neTi kwintsimbi engagqwaliyo okanye izinto zokunciphisa ezifana neC, Si, Mn, S, kunye neF, ngeenjongo ezahlukeneyo kunye nokusetyenziswa. Ukuqina kwemvula (ukuqina kwesedimentation) intsimbi engagqwaliyo kunye nentsimbi engagqwaliyo ephindwe kabini nazo ziye zaphuhliswa ngempumelelo.

Qaphela: Izinto zentsimbi engagqwaliyo ezisetyenziswa rhoqo kwiivalvu ziquka i-CF8, i-CF8M, i-CF3, kunye ne-CF3M. Kukwakho neentsimbi ze-super duplex, ezifana ne-4A, i-5A, kunye ne-6A.

Iimpawu zeNtsimbi Engagqwaliyo

4. Izinto kunye nezinto ekufuneka uziqwalasele xa ukhetha i-Stainless Steel Valve

4.1. Uhlalutyo lweMigangatho yoSebenzayo kunye neNdalo esiNgqongileyo:

Izinto eziphambili ekufuneka ziqwalaselwe xa kukhethwa kukubola, ubushushu, uxinzelelo, kunye nesantya sokuhamba kwesixhobo. Umzekelo, kwiindawo eziqulethe ii-ion ze-chloride (ezifana namanzi olwandle okanye i-brine) okanye i-chemical media ebola kakhulu, intsimbi engagqwaliyo ye-316 okanye ye-316L enganyangekiyo kukubola kufuneka ibekwe phambili kunentsimbi engagqwaliyo yesiqhelo ye-304.

4.2. Ukhetho lwezinto zentsimbi engagqwaliyo:

Iindidi ezahlukeneyo zentsimbi engagqwaliyo zibonisa umahluko omkhulu ekusebenzeni, zifuna ukufana okuchanekileyo ngokusekelwe kwiimeko zokusebenza.

• I-304 Stainless Steel: Iqulethe i-18% ye-chromium kunye ne-8% ye-nickel (i-18/8 stainless steel), inokumelana nokugqwala okuhle kunye neempawu zoomatshini, ifanelekile kwiindawo ezininzi ezingezizo ezigqithisileyo, ezifana nokunikezelwa kwamanzi kamasipala, ishishini lokutya, kunye neenkqubo ze-HVAC. Amandla ayo okuxinana ≥520MPa kunye nokwandiswa ≥40%.
• I-316/316L Stainless Steel: Ngokusekelwe kwi-304, i-molybdenum (Mo) yongezwa, nto leyo ephucula kakhulu ukumelana nokugqwala, ingakumbi ukumelana nokugqwala. Ifanelekile kwiinjineli zaselwandle, ukususwa kwetyuwa emanzini olwandle, iitanki zokugcina iikhemikhali, kunye nezinye iindawo eziqulethe ii-ion ze-chloride okanye ezinobuthi obuqinileyo. I-316L inomxholo ophantsi wekhabhoni (≤0.03%), nto leyo ethintela ngempumelelo ukugqwala kwe-intergranular emva kokugqwala, nto leyo eyenza ifaneleke kwiivalvu ezinkulu ezifuna ukugqwala.
• 3. Ezinye Izinto: Kwizinto ezifuna amandla aphezulu kunye nokumelana nokuguguleka (ezifana neziqu zevalvu kunye neentloko zevalvu), intsimbi engagqwaliyo ye-martensitic (efana ne-410) ingasetyenziswa; kwiimeko ezigqithisileyo zoxinzelelo oluphezulu, ukugqwala okuphezulu, kunye nesantya sokuhamba kwamanzi aphezulu (njengokukhupha ioyile negesi), intsimbi engagqwaliyo ye-duplex (efana ne-2205), enamandla aphindwe kabini kune-304, ingaqwalaselwa.

4.3. Iiparameter zeValve kunye neemfuno zokutywina:

Ubungakanani bevalvu efanelekileyo (i-nominal diameter DN) kufuneka ikhethwe ngokusekelwe kubungakanani bombhobho kunye neemfuno zokuhamba kwenkqubo, kwaye kufuneka ihambelane ngokungqongqo nomlinganiselo woxinzelelo lokusebenza kwenkqubo. Ukusebenza kokutywina kuchaphazela ngokuthe ngqo ukusebenza; ke ngoko, isakhiwo sokutywina esifanelekileyo kunye nezinto (ezifana nezitywina ezithambileyo ze-PTFE okanye izitywina eziqinileyo ze-alloy) kufuneka zikhethwe ngokweempawu zesixhobo.

5. Iimpawu kunye nosetyenziso lweeValve zeNtsimbi Engagqwaliyo

5.1. Iimpawu zoBume kunye noHlelo:

Ngaphandle kokuba zihlelwe ngokwesakhiwo ngokweentlobo ezidadayo, ezizinzileyo, nezizinzileyo, iivalvu zebhola zentsimbi engagqwaliyo zinokuhlelwa ngokwesakhiwo somzimba weevalvu zibe yinxalenye enye (imbobo encitshisiweyo, isakhiwo esincinci), iziqwenga ezimbini (imbobo epheleleyo), kunye neziqwenga ezintathu (isakhiwo esidibeneyo, ukuqhaqhwa nokugcinwa lula, ukumelana noxinzelelo oluphezulu). Uluhlu lobubanzi oluqhelekileyo lubanzi, luqhele ukuba phakathi kwe-DN15 ukuya kwi-DN200.
