I-API 594 ngumgangatho weAmerican Petroleum Institute oquka uyilo, imathiriyeli, imilinganiselo, uvavanyo, kunye nokuhlolwa kweevalvu zokutshekisha. Ngokukodwa, igxininise kwiinkcukacha zee-valve zokujonga iipleyiti ezimbini, ezikwabizwa ngokuba yi-wafer check valves, esetyenziswa ngokubanzi kumashishini ahlukeneyo kuquka i-oyile kunye negesi, i-petrochemical, kunye nokucoca. ngokubhekiselele kulwakhiwo lwabo, ukulinganiswa kobushushu boxinzelelo, izixhobo, ukuqinisekiswa koyilo, kunye neenkqubo zokuvavanya. Lo mgangatho uqinisekisa ukuba i-valve ihlangabezana nemilinganiselo ethile yokusebenza kunye nokhuseleko lwezicelo ezibandakanya ukukhuselwa kwe-reverse. ulwakhiwo olulula olufanelekileyo ukufakwa phakathi kweeflange. Ezi valves zidla ngokuthandwa ngenxa yokuhla koxinzelelo oluphantsi, ukutywinwa okuthembekileyo, kunye nokulula ukufakela kunye nokugcinwa.Ukuba unemibuzo ethile malunga neevalvu zokujonga ipleyiti ezimbini ezenziwe kwimigangatho ye-API 594 okanye zifuna iinkcukacha ezingaphezulu malunga neenkcukacha zabo, izinto, okanye iimfuno zokuvavanya, nceda uzive ukhululekile ukubuza ulwazi oluthe kratya.
1. ubude besakhiwo bufutshane, ubude besakhiwo buyi-1/4 ukuya kwi-1/8 kuphela yevalve yokukhangela iflange.
2. ubungakanani obuncinci, ubunzima obukhanyayo, ubunzima bayo buyi-1/4 ukuya kwi-1/20 yevalve yokujonga ukuvalwa okucothayo.
3. i-disc ye-valve yokujonga i-clamp ivala ngokukhawuleza, kwaye uxinzelelo lwehamile yamanzi luncinci
4. itshekhi umbhobho othe tyaba okanye othe nkqo ungasetyenziswa, kulula ukuyifaka
5. i-clamp check valve flow path igudile, ukuxhathisa ulwelo kuncinci
6. isenzo esibuthathaka, ukusebenza kakuhle kokutywina
7. i-disc stroke imfutshane, i-clamping check valve yokuvala impembelelo incinci
8. Isakhiwo esipheleleyo, esilula kwaye sihlangene, isimo esihle
9. ubomi benkonzo ende, ukuthembeka 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.
