I-API 594 Dual plate check valve isetyenziselwa imibhobho ecocekileyo kunye nemizi-mveliso, ukhuseleko lokusingqongileyo, unyango lwamanzi, unikezelo lwamanzi kunye nemibhobho yokukhupha amanzi kwizakhiwo eziphakamileyo ukuthintela ukuhamba okungasemva kwemidiya. I-check valve isebenzisa uhlobo lwe-wafer, i-butterfly plate inee-semicircles ezimbini, kwaye isebenzisa i-spring ukunyanzelisa ukuseta kwakhona, umphezulu wokutywina unokuba yi-welding surface surface material engagugiyo okanye i-raber lining, uluhlu lokusetyenziswa lubanzi, kwaye ukutywina kuthembekile.

Iindawo zokuvula nokuvala zevalvu yokujonga ye-API 594 zixhomekeke ekuhambeni nasekuqineni kwe-medium ukuze ivuleke okanye ivale ngokwazo ukuthintela i-medium ukuba ingabuyeli umva. Ivalvu ibizwa ngokuba yivalvu yokujonga. Iivalvu zokujonga ziyinxalenye yeevalvu ezizenzekelayo, ezisetyenziswa kakhulu kwiipayipi apho i-medium ihamba kwicala elinye, kwaye zivumela kuphela i-medium ukuba ihambe kwicala elinye ukuthintela iingozi.

Ngokwesakhiwo sevalvu yokujonga, ingahlulwa ibe ziintlobo ezintathu:ivalvu yokujonga ukuphakama, ivalvu yokujonga iswingkwayeivalvu yokujonga i-waferIivalvu zokuhlola iilifti zinokwahlulwa zibe ziintlobo ezimbini: ezithe nkqo nezithe tye. Iivalvu zokujonga iiswing zahlulwe zibe ziintlobo ezintathu: ivalvu enye, ivalvu ephindwe kabini kunye nevalvu ezininzi. Ivalvu yokujonga iiwafer luhlobo oluthe tye. Ivalvu yokujonga yivalvu enokuthintela ngokuzenzekelayo ulwelo ukuba lungabuyeli umva. Iflaphu yevalvu yevalvu yokujonga ivula phantsi kwesenzo soxinzelelo lolwelo, kwaye ulwelo luhamba ukusuka kwicala lokungena ukuya kwicala lokukhupha. Xa uxinzelelo kwicala lokungena luphantsi kunolo lukwicala lokukhupha, iflaphu yevalvu ivalwa ngokuzenzekelayo phantsi kwesenzo somahluko woxinzelelo lolwelo, umxhuzulane kunye nezinye izinto zokuthintela ulwelo ukuba lungabuyeli umva.

Ukuba ufuna iinkcukacha ezithe vetshe malunga neevalvu nceda unxibelelane nesebe lokuthengisa le-NSW (newsway valve)

Ulwazi lobungcali lweevalvu zokujonga ze-API 594

Yintoni i-API 594 Standard

I-API 594, eyasekwa yi-American Petroleum Institute (API), ngumgangatho ocacileyo weshishini onesihloko esithi “Check Valve: Flanged, Lug, Wafer, kunye neButt-welding Types.” Le nkcazelo ibalulekileyo ilawula uyilo, ukukhethwa kwezinto, ubukhulu besakhiwo, ukunyamezela uxinzelelo-ubushushu, kunye neenkqubo zokuhlola/ukuvavanya iivalve zokujonga imboni.

Ububanzi kunye nokusetyenziswa kwe-API 594

I-API 594 isebenza kuzo zombini iivalvu zokujonga zohlobo A (ezimfutshane zobuso ngobuso) kunye nohlobo B (ezinde zobuso ngobuso). Igubungela ngokupheleleyo uyilo olwahlukeneyo lwezakhiwo, kuquka:

• Iivalvu zokujonga iSwing
• Iivalvu zokujonga ukuphakanyiswa
• Ivalvu yokujonga iipleyiti ezimbini /Ivalvu yokujonga iWafers
• Iivalvu zokujonga iibhabhathane
  Lo mgangatho usebenza kwiivalvu zobukhulu obuqala kwi-DN 150 (NPS 6) ukuya kwi-DN 400 (NPS 16). Ulawula iivalvu ezakhiwe ngezinto ezifana ne-grey cast iron, i-ductile iron, i-carbon steel, i-stainless steel, kunye nezinye ii-alloys.

Iimfuno zoYilo kunye nezinto ze-API 594

• Ukuthobela uYilo: Uyilo lwevalvu kufuneka lulandele ngokungqongqo iinkcukacha ze-API 594.
• Imigangatho yoQhagamshelo: Uqhagamshelo lwesiphelo (olune-flanged, i-lug, i-wafer, i-butt-weld) kufuneka luhambelane nobukhulu kunye novavanyo oluchazwe kwimigangatho ekhankanyiweyo efana ne-ASME B16.11 (i-Socket Welding & Threaded) kunye ne-ASME B16.15 (i-Cast Bronze Threaded Fittings - iKlasi 125 kunye ne-250).
• Ukukhethwa kwezinto: Izinto zomzimba ezivumelekileyo ziquka intsimbi engwevu, intsimbi ethambileyo, intsimbi yekhabhoni, intsimbi engatyiwayo, kunye nee-alloys ezahlukeneyo. Okubaluleke kakhulu, izinto zomphezulu wokutywina kufuneka zihambelane nesixhobo esithile senkonzo ukuqinisekisa ukuthembeka nokuthintela ukugqwala okanye ukonakala.

Ulwakhiwo lweValve kunye neendlela zoQhagamshelo

I-API 594 ihlela iivalvu ngokusekelwe kuqhagamshelo lwazo lokugqibela:

• Uhlobo lweFlanged: Isebenzisa iziphelo zeflange ukuze iqhagamshele ii-bolts kwii-flanges zepayipi. Ilungele iinkqubo zeflanges eziqhelekileyo ezifuna ukuhlanganiswa/ukuqhaqhwa okulula.
• Uhlobo lwe-Butt-Weld: Iqulethe iziphelo ezijijekileyo zokuwelda ngqo kumbhobho. Yenzelwe ukusetyenziswa kwizicelo zobushushu obuphezulu, uxinzelelo oluphezulu, okanye iinkonzo ezibalulekileyo apho ukuqina kokuvuza kubaluleke kakhulu.
• Uhlobo lweLug: Ifaka ii-inserts ezinemisonto (ii-lugs) emzimbeni wevalvu, ivumela ukufakwa phakathi kwee-flanges kusetyenziswa ii-bolts kwii-lugs, ezifanelekileyo kwinkonzo engapheliyo.
• Uhlobo lweWafer: Inika uyilo oluncinci nolukhaphukhaphu olufakwe phakathi kweeflanges kusetyenziswa iibholithi ezinde ezigubungela yonke ipayipi. Isebenza kakuhle kwiinkqubo zemibhobho yemizi-mveliso.

Uvavanyo loxinzelelo-lobushushu

I-API 594 ichaza ngokungqongqo ukulinganiswa koxinzelelo-ubushushu (PT) kwiivalvu zokujonga ngokusekelwe kwizinto, uyilo, kunye nobukhulu. Ezi zilinganiso ziqinisekisa ukuba ivalvu inokusebenza ngokukhuselekileyo nangokuthembekileyo phantsi kweemeko zobushushu ezithile kunye noxinzelelo kulo lonke ixesha lokusebenza kwayo. Abayili kunye nabaqhubi kufuneka banamathele ngokungqongqo kule mida ye-PT.

Iimfuneko zoHlolo noVavanyo

Zonke iivalvu zokujonga ze-API 594 ziyahlolwa kwaye zivavanywe ngokunyanzelekileyo ukuqinisekisa ukusebenza kunye nokuthembeka. Iiprotokholi zovavanyo zilandela ngokungqongqo imigangatho yoshishino, ngokuyintloko:

• I-API 598: Ukuhlolwa noVavanyo lweeValve (igubungela iimvavanyo zeqokobhe, iimvavanyo zesihlalo, iimvavanyo zesihlalo esingasemva, njl.njl.).
• I-ASME B16.10: Ubukhulu beeValve zoBuso noBuso kunye noBucala noBucala.
  Uvavanyo oluphambili luquka:
• Uvavanyo lwamandla eShell: Luqinisekisa ukuqina komzimba oqulethe uxinzelelo kunye nokuqina kwebhonethi.
• Uvavanyo lokuVula iSitulo: Luqinisekisa amandla okuvala indlela yokuvala.
• Uvavanyo Lokuvala Uxinzelelo Oluphezulu: Luqinisekisa ukutywinwa phantsi koxinzelelo olulinganisiweyo.
• Uvavanyo Lokuvala Uxinzelelo Oluphantsi: Luqinisekisa ukutywinwa phantsi koxinzelelo oluncinci.
• Uvavanyo lwesihlalo sangasemva (ukuba luyasebenza): Luqinisekisa ukutywinwa kwesiqu phantsi koxinzelelo xa ivalvu ivuliwe ngokupheleleyo.
