I-API 594 Dual plate check valve isetshenziselwa amapayipi ahlanzekile kanye nezimboni, ukuvikelwa kwemvelo, ukwelashwa kwamanzi, ukuhlinzekwa kwamanzi kanye namapayipi okukhipha amanzi ezakhiweni eziphakeme ukuvimbela ukugeleza okuphambene kwemidiya. I-check valve isebenzisa uhlobo lwe-wafer, ipuleti le-butterfly liyi-semicircles ezimbili, futhi isebenzisa isiphethu ukuphoqelela ukusetha kabusha, indawo yokuvala ingaba yi-welding surface body material engagugi noma i-raber lining, ububanzi bokusetshenziswa bubanzi, futhi ukuvala kuthembekile.

Izingxenye zokuvula nokuvala zevalvu yokuhlola ye-API 594 zithembele ekugelezeni nasemandleni e-medium ukuze zivuleke noma zivale zodwa ukuze kuvinjelwe i-medium ukuthi igeleze emuva. Ivalvu ibizwa ngokuthi ivalvu yokuhlola. Amavalvu okuhlola angaphansi kwesigaba samavalvu azenzakalelayo, asetshenziswa kakhulu emapayipini lapho i-medium igeleza khona ohlangothini olulodwa, futhi avumela kuphela i-medium ukuthi igeleze ohlangothini olulodwa ukuvimbela izingozi.

Ngokwesakhiwo se-check valve, ingahlukaniswa ngezinhlobo ezintathu:ivalvu yokuhlola ukuphakama, ivalvu yokuhlola ukujikafuthiivalvu yokuhlola i-waferAmavalvu okuhlola ukuphakama angahlukaniswa ngezinhlobo ezimbili: aqondile navundlile. Amavalvu okuhlola ukujika ahlukaniswe ngezinhlobo ezintathu: ivalvu eyodwa, ivalvu ephindwe kabili kanye nevalvu eminingi. Ivalvu yokuhlola i-wafer iwuhlobo oluqondile. Ivalvu yokuhlola iyivalvu engavimbela ngokuzenzakalelayo uketshezi ukuthi lugeleze emuva. I-flap yevalvu yokuhlola ivuleka ngaphansi kwesenzo sokucindezela koketshezi, futhi uketshezi lugeleza lusuka ohlangothini lokungena luye ohlangothini lokukhipha. Uma ingcindezi ohlangothini lokungena iphansi kunaleyo ohlangothini lokukhipha, i-flap yevalvu ivalwa ngokuzenzakalelayo ngaphansi kwesenzo somehluko wokucindezela koketshezi, amandla adonsela phansi kanye nezinye izinto zokuvimbela uketshezi ukuthi lugeleze emuva.

Uma udinga imininingwane eyengeziwe ngama-valve sicela uxhumane nomnyango wokuthengisa we-NSW (newsway valve)

Ulwazi lobuchwepheshe lwama-valve okuhlola e-API 594

Iyini i-API 594 Standard

I-API 594, eyasungulwa yi-American Petroleum Institute (API), iyindinganiso ecacile embonini enesihloko esithi “Hlola Amavalvu: Izinhlobo Zokushisela Ezine-Flanged, Lug, Wafer, kanye Nezinqe.” Le ncazelo ebalulekile ilawula ukwakheka, ukukhethwa kwezinto, ubukhulu besakhiwo, ukubekezelelana kokucindezela nokushisa, kanye nezinqubo zokuhlola/zokuhlola zamavalvu okuhlola ezimbonini.

Ububanzi kanye Nokusetshenziswa kwe-API 594

I-API 594 isebenza kokubili kumavalvu okuhlola ohlobo A (olufushane ubuso nobuso) kanye nohlobo B (olude ubuso nobuso). Ihlanganisa ngokuphelele imiklamo eyahlukene yesakhiwo, okuhlanganisa:

• Amavalvu Okuhlola Ukujika
• Amavalvu Okuhlola Ukuphakamisa
• I-Dual Plate Check Valve /I-Wafer Check Valves
• Amavalvu Okuhlola Uvemvane
  Indinganiso iyasebenza kuma-valve osayizi asukela ku-DN 150 (NPS 6) kuya ku-DN 400 (NPS 16). Ilawula ama-valve akhiwe ngezinto ezifana ne-grey cast iron, i-ductile iron, i-carbon steel, i-stainless steel, nezinye izinhlobo ze-alloys.

Izidingo Zomklamo Nezinto Ezibalulekile ze-API 594

• Ukuhambisana Nomklamo: Umklamo wevalvu kumele unamathele ngokuqinile ezimisweni ze-API 594.
• Izindinganiso Zokuxhumana: Ukuxhumeka kokugcina (okune-flanged, i-lug, i-wafer, i-butt-weld) kumele kuhambisane nobukhulu kanye nezilinganiso ezichazwe ezindinganisweni ezibhekiselwe kuzo njenge-ASME B16.11 (Socket Welding & Threaded) kanye ne-ASME B16.15 (Cast Bronze Threaded Fittings – Class 125 & 250).
• Ukukhethwa Kwezinto: Izinto zomzimba ezivunyelwe zifaka phakathi insimbi empunga, insimbi ethambile, insimbi yekhabhoni, insimbi engagqwali, kanye nezinhlobo ezahlukene ze-alloys. Okubaluleke kakhulu, izinto zokuvala kumele zihambisane nendawo ethile yesevisi ukuqinisekisa ubuqotho nokuvimbela ukugqwala noma ukuwohloka.

Isakhiwo seValve kanye Nezindlela Zokuxhuma

I-API 594 ihlukanisa ama-valve ngokusekelwe ekuxhumekeni kwawo kokuphela:

• Uhlobo Olugobekile: Isebenzisa iziphetho ezigobekile ukuze kuxhunywe amabhawodi kuma-flange amapayipi. Ilungele izinhlelo ezijwayelekile zamapayipi e-flange ezidinga ukuhlanganiswa/ukuhlukaniswa okulula.
• Uhlobo Lokushisela Izinqe: Iqukethe iziphetho ezigobile zokushisela ngqo epayipini. Yakhelwe ukusetshenziswa kwezinga lokushisa eliphezulu, umfutho ophezulu, noma isevisi ebalulekile lapho ubuqotho obungavuzi bubaluleke kakhulu.
• Uhlobo Lwesigubhu: Sifaka ama-insert anezintambo (ama-lugs) emzimbeni we-valve, okwenza kube lula ukufaka phakathi kwama-flange kusetshenziswa ama-bolts phakathi kwama-lugs, afanelekela isevisi engapheli.
• Uhlobo lwe-Wafer: Inikeza umklamo omncane, olula ofakwe phakathi kwama-flange kusetshenziswa amabhawodi amade ahlanganisa lonke ipayipi. Isebenza kahle kakhulu ezinhlelweni zamapayipi ezimboni.

Izilinganiso Zokushisa Nokucindezela

I-API 594 ichaza ngokunembile izilinganiso zokucindezela-ukushisa (PT) zama-valve okuhlola ngokusekelwe ezintweni ezibonakalayo, umklamo, kanye nosayizi. Lezi zilinganiso ziqinisekisa ukuthi i-valve ingasebenza ngokuphephile nangokuthembekile ngaphansi kwezimo zokushisa ezicacisiwe kanye nezingcindezi kuyo yonke impilo yayo yokusebenza. Abaklami nabaqhubi kumele banamathele ngokuqinile kule mikhawulo ye-PT.

Izidingo Zokuhlola Nokuhlola

Wonke ama-valve okuhlola e-API 594 ahlolwa futhi ahlolwe ngokuphoqelekile ukuqinisekisa ukusebenza kanye nobuqotho. Izinqubo zokuhlola zilandela ngokuqinile amazinga omkhakha, ikakhulukazi:

• I-API 598: Ukuhlolwa Nokuhlolwa Kwevalvu (ihlanganisa ukuhlolwa kwegobolondo, ukuhlolwa kwesihlalo, ukuhlolwa kwesihlalo sangemuva, njll.).
• I-ASME B16.10: Ubukhulu Bobuso Nobuso kanye Nobuphelele Bama-Valve.
  Ukuhlolwa okubalulekile kufaka phakathi:
• Ukuhlolwa Kwamandla Egobolondo: Kuqinisekisa ubuqotho bomzimba oqukethe ingcindezi kanye ne-bonnet.
• Ukuhlolwa Kokuvuza Kwesihlalo: Kuqinisekisa ikhono lokuvala lendlela yokuvala.
• Ukuhlolwa Kokuvalwa Kokucindezela Okuphezulu: Kuqinisekisa ukuvalwa ngaphansi kwengcindezi elinganisiwe.
• Ukuhlolwa Kokuvalwa Okuphansi Kokucindezela: Kuqinisekisa ukuvalwa ngaphansi kwengcindezi encane.
• Ukuhlolwa Kwesihlalo Sangemuva (uma kusebenza): Kuqinisekisa ukuvalwa kwesiqu ngaphansi kwengcindezi lapho ivalvu ivuliwe ngokuphelele.
