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 yesiqhelo yokuvalwa okucothayo.
3. i-disc ye-valve yokujonga i-clamp ivala ngokukhawuleza, kwaye uxinzelelo lwehamile yamanzi luncinci
4. itshekhi ivalve 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 wokusika, kwaye ngenxa yokuba ukutshintshwa kwe-valve seat port ilingana ne-stroke ye-valve disc, ikulungele kakhulu ukulungiswa. yesantya sokuhamba.Ke ngoko, olu hlobo lwevalve lufanelekile kakhulu ukunqunyulwa okanye ukulawulwa kunye ne-throttling.
