Umgangatho we-API 6D uchaza iimfuno zeevalvu zemibhobho, kubandakanywa neenkcukacha zeentlobo ezininzi zeevalvu, ukusuka kwiivalvu zesango ukuya kwiivalve zokukhangela. Ivalve yokujonga ujingi yezibuko eyenzelwe ngokwe-API 6D ihlangabezana nemigangatho ethile yoshishino kunye neemfuno zoyilo, izixhobo, imilinganiselo, kunye neenkqubo zovavanyo. Ubungakanani obufana nombhobho ofakwe kuwo. Olu luyilo lunciphisa ukuhla koxinzelelo kunye noxhathiso lokuqukuqela, nto leyo evumela ukuhamba kakuhle kolwelo kwivalvu.Ivalve yokujonga ujingi isebenza ngokuvumela ukuqukuqela kwicala elinye ngelixa ukuthintela ukubuyela umva kwelinye icala. I-disc ejikelezayo ngaphakathi kwevalve ivula kwicala lokuhamba kwaye ivale ukuthintela ukuhamba okubuyela emva. Olu hlobo lwevalve lusetyenziswa ngokuqhelekileyo kwizicelo apho uthintelo lokubuyela umva lubalulekile, njengemibhobho, iindawo zokucoca, kunye nezityalo zenkqubo.Iivalve ezihambelana ne-API 6D ziyilelwe kwaye zivavanywe ukumelana noluhlu lweengcinezelo zokusebenza, amaqondo obushushu, kunye neentlobo zolwelo, ukuqinisekisa. umsebenzi othembekileyo nokhuselekileyo kwiindawo ezifunayo zoshishino.Ukuba ufuna ulwazi oluthe ngqo malunga ne-API 6D epheleleyo ye-port swing check valve okanye unemibuzo engaphezulu, zikhululeke ukubuza iinkcukacha ezithe vetshe.
1. Ubude besakhiwo bufutshane, kwaye ubude besakhiwo buyi-1/4 ukuya kwi-1/8 kuphela ye-valve yokukhangela i-flange;
2. Ubungakanani obuncinci, ubunzima obukhanyayo, kunye nobunzima bayo bu-1/4 ukuya kwi-1/20 kuphela ye-valve ye-micro-retarding check valve;
3. I-disc ye-valve ivala ngokukhawuleza kwaye uxinzelelo lwehamile yamanzi luncinci;
4. Imibhobho ethe tyaba okanye ethe nkqo ingasetyenziswa, kulula ukuyifaka;
5. Umjelo wokuhamba kakuhle, ukunganyangeki kwamanzi aphantsi;
6. Isenzo esibuthathaka, ukusebenza kakuhle kokutywina;
7. Ukubetha okufutshane kwediski ye-valve, impembelelo encinci ye-valve yokuvala;
8. Isakhiwo ngokubanzi, ilula kwaye idibene, imilo emihle;
9. Ubomi benkonzo ende kunye nokuthembeka okuphezulu.
Ngethuba lokuvula kunye nokuvala i-valve yeglobhu yentsimbi ekhandiweyo, ngenxa yokuba i-friction phakathi kwe-disc kunye ne-surface yokutywina ye-valve yomzimba incinci kune-valve yesango, ayigugi.
Ukuvula okanye ukuvala i-stroke ye-valve stem ifutshane, kwaye inomsebenzi othembekileyo wokusikwa, kwaye ngenxa yokuba utshintsho lwe-valve seat port lulingana ne-stroke ye-valve disc, ilungele kakhulu ukulungiswa. yesantya sokuhamba. Ke ngoko, olu hlobo lwevalve lufanelekile kakhulu ukunqunyulwa okanye ukulawulwa kunye ne-throttling.
