Ufakelo lwevalvu yebhabhathane, imiyalelo yokusetyenziswa kunye nokugcinwa kwayo—Ivalve ye-TWS

1. Ngaphambi kofakelo, kuyimfuneko ukujonga ngononophelo ukuba uphawu kunye nesatifikethi seivalve yebhabhathaneukuhlangabezana neemfuno zokusetyenziswa, kwaye kufuneka icocwe emva kokuqinisekiswa.

2. Ivalve yebhabhathane inokufakwa kuyo nayiphi na indawo kumbhobho wesixhobo, kodwa ukuba kukho isixhobo sokuhambisa, kufuneka sifakwe ngokuthe tye, oko kukuthi, isixhobo sokuhambisa kufuneka sime nkqo kwindawo yombhobho othe tye, kunye nofakelo. isikhundla sikulungele ukusebenza kunye nokuhlolwa.

3. Iibholiti zokudibanisa phakathi kwevalve yebhabhathane kunye nombhobho kufuneka ziqiniswe amaxesha amaninzi kwicala lediagonal ngexesha lofakelo. Iibholiti zokudibanisa akufanele ziqiniswe ngexesha elinye ukukhusela uxhulumaniso lwe-flange ukuba lungavuzi ngenxa yamandla angalinganiyo.

4. Xa uvula i-valve, vula i-handwheel counterclockwise, xa uvala i-valve, vula i-handwheel nge-clockwise, kwaye uyijikeleze ngokuhambelana nezikhombisi zokuvula nokuvala.

5. Niniivalve yebhabhathane yombaneushiya umzi-mveliso, ukubetha kwendlela yokulawula kuhlengahlengiswe. Ukuze uthintele indlela engafanelekanga yoxhulumaniso lwamandla, umsebenzisi kufuneka ayivule ngesandla kwindawo evulekileyo yesiqingatha ngaphambi kokuvula amandla okokuqala, kwaye ukhangele isalathiso sepleyiti yesalathisi kunye nokuvulwa kwevalve. isalathiso siyafana.

6. Xa i-valve isetyenziswa, ukuba kukho impazamo efunyenweyo, yeka ukuyisebenzisa ngokukhawuleza, fumana isizathu kwaye ucime impazamo.

7. Ukugcinwa kwevalvu: Iivalvu ezingafakwanga nezingasetyenziswanga kufuneka zigcinwe kwigumbi elomileyo, zipakishwe kakuhle, yaye zingavunyelwa ukuba zigcinwe kwindawo evulekileyo ukuze kuthintelwe umonakalo nokudleka. Iivalvu ezigcinwe ixesha elide kufuneka zihlanjululwe rhoqo, zomiswe, kwaye zifakwe ngeoli echasene ne-rust. Iipleyiti ezingaboniyo kufuneka zisetyenziswe kuzo zombini iziphelo zevalve ukukhusela i-flange yokutywina indawo kunye nokukhusela ukungcola ekungeneni ngaphakathi ngaphakathi.

8. Ukuthuthwa kwe-valve: I-valve kufuneka ifakwe kakuhle xa ithunyelwa, kwaye kufuneka ifakwe ngokwekhontrakthi ukuqinisekisa ukuba iinxalenye azonakaliswanga okanye zilahlekile ngexesha lokuthutha.

9. Iwaranti yesivalo: Isivalo sisetyenziswa kunyaka omnye, kodwa hayi ngaphezulu kweenyanga ezili-18 emva kokuziswa. Ukuba ngokwenene kungenxa yeziphene zezinto eziphathekayo, umgangatho wokuvelisa okungenangqiqo, uyilo olungenangqiqo kunye nomonakalo ekusebenziseni okuqhelekileyo, kuya kuqinisekiswa lisebe lokuhlola umgangatho wefektri yethu. Inoxanduva lwewaranti ngexesha lewaranti.
