ImiGangatho yokuVelisa
Ukuvelisa phantsi kwe-API 6D kufuna ulawulo olungqongqo lwekhwalithi kunye nokuthotyelwa kwemigangatho yehlabathi. Zonke iivalvu kufuneka zenziwe kusetyenziswa iindlela ezichanekileyo eziqinisekisa ukuchaneka kunye nokuhambelana kwimilinganiselo yevalvu kunye nokusebenza. Inkqubo yokuvelisa ibandakanya uvavanyo olubanzi, olufana noxinzelelo kunye novavanyo lokuvuza, ukuqinisekisa ukuba ivalve nganye isebenza ngokugqibeleleyo ngaphambi kokuba isetyenziswe kwinkqubo yepayipi.
Amanqaku oxinzelelo kunye nobushushu
Uxinzelelo kunye neqondo lokushisa kwiivalvu ezigutyungelwe phantsi kwe-API 6D zixhomekeke kwizinto ezahlukeneyo, kubandakanywa uhlobo lwevalve, izinto ezisetyenzisiweyo, kunye nesicelo esithile. Apha ngezantsi kujongwe ngokubanzi kunye nedatha eqhelekileyo esekwe kwimigangatho yoshishino:
Ixabiso loxinzelelo
● Ukulinganiswa koxinzelelo lwevalve kubhekiselele kuxinzelelo oluphezulu olunokuthi ivelu ikwazi ukuphatha ngokukhuselekileyo kwiqondo lobushushu elithile ngaphandle kokubeka esichengeni isidima sayo sesakhiwo okanye ukusebenza kokutywina.
● Kwii-valve ze-API 6D, ukulinganiswa koxinzelelo kuhlelwe kwiiklasi zoxinzelelo (iiklasi ze-ANSI), ngokuqhelekileyo ukusuka kwi-150 ukuya kwi-2500. Olu didi lumisela uxinzelelo oluvumelekileyo lokusebenza lwe-valve ngokusekelwe kuyilo kunye nezinto eziphathekayo.
Imizekelo yeKlasi yoxinzelelo
● Udidi lwe-150: Isetyenziselwa iinkqubo zoxinzelelo oluphantsi, ngokuqhelekileyo ukuya kwi-285 psi (iipounds nge-intshi yesikwere).
● Udidi lwe-300: Ukusingatha uxinzelelo ukuya kwi-740 psi.
● Iklasi ye-600: Ilinganiswe kwiinkqubo ezisebenza kwi-1480 psi.

Izinto eziphathekayo
Izinto ezisetyenziselwa ii-valve ze-API 6D kufuneka zihambelane nesethi yezikhokelo ezithile eziqinisekisa ukuqina kunye namandla. Iimpawu eziphambili zemathiriyeli ziquka:
Umzimba kunye neMathiriyeli yeBhonethi:Imizimba yevalvu kunye neebhonethi kufuneka zenziwe kwizinto ezinokumelana noxinzelelo lwangaphakathi kunye neemeko zokusingqongileyo. Izinto eziqhelekileyo ziquka i-carbon steels, i-stainless steels, kunye ne-alloy steels. Ukukhethwa kwezinto kuxhomekeke kubungakanani bevalve, iklasi yoxinzelelo, kunye nobushushu bokusebenza.
Izinto zokutywina:Izinto zokutywina kwii-valve ze-API 6D, kubandakanywa i-gaskets, i-seal, kunye nokupakisha, zenzelwe ukukhusela ukuvuza phantsi koxinzelelo oluphezulu. Ezi zixhobo kufuneka zihlangabezane nokumelana neekhemikhali kunye neemfuno zokunyamezela ubushushu ezichazwe yi-valve ekujoliswe kuyo.
Iibholidi kunye neFasteners:I-bolting esetyenziswa kwiivalvu ze-API 6D kufuneka ihambelane nemigangatho eyongezelelweyo, efana ne-API 20E ye-carbon steel kunye ne-API 20F ye-corrosion{3}}i-resistant bolting. Ibholithi iqinisekisa ubume besakhiwo phantsi kweemeko zoxinzelelo olukhulu kwaye kufuneka ithathwe kubavelisi abafanelekileyo.
Sika izixhobo:Ukunquma iindawo ezifana nezihlalo, iziqu, kunye neediski zihlala zenziwe kwizinto ezifana nentsimbi engatyiwa okanye i-alloys ephezulu ukuqinisekisa ukuxhathisa ukunxiba, ukubola, kunye namaqondo obushushu aphezulu.
-Imida yoxinzelelo:Izixhobo ezinjengeenkxaso, iziqhotyoshelo ze-actuator, kunye nezixhobo aziyonxalenye yomda woxinzelelo kodwa kufuneka zenziwe kwizinto ezihlala ixesha elide ukuxhasa umsebenzi wevalve kunye nokuthembeka.
