Ukufakwa kwamavalvu ebhola ahlanganiswe ngokuphelele
(1) Ukuphakamisa. Ivalvu kufanele iphakanyiswe ngendlela efanele. Ukuze uvikele isiqu sevalvu, ungabophi iketanga lokuphakamisa esondweni lesandla, ebhokisini legiya noma ku-actuator. Ungasusi izivalo zokuvikela kuzo zombili iziphetho zesikhafu sevalvu ngaphambi kokushisela.
(2) Ukushisela. Ukuxhumeka nepayipi eliyinhloko kushisele. Ikhwalithi yomthungo wokushisela kumele ihlangabezane nezinga le-“Radiography of Welded Joints of Disk Flexion Fusion Welding” (GB3323-2005) Grade II. Ngokuvamile, ukushisela okukodwa akukwazi ukuqinisekisa ngokugcwele zonke izimfanelo. Ngakho-ke, lapho u-oda ivalvu, umenzi kufanele acele umenzi ukuthi engeze u-1.0m kuzo zombili izinhlangothi zevalvu. Ishubhu lesleeve, uma umthungo wokushisela ungashiseleki, ubude obanele bokunquma umthungo wokushisela ongashiseleki bese ushiseleka kabusha. Lapho ivalvu yebhola kanye nepayipi kushiseleka, ivalvu kufanele ibe sesimweni esivulekile ngokuphelele esingu-100% ukuvimbela ivalvu yebhola ukuthi ingonakaliswa yi-slag yokushisela echithekayo, futhi ngesikhathi esifanayo iqinisekise ukuthi ivalvu Izinga lokushisa le-seal yangaphakathi alidluli ama-degree Celsius angu-140, futhi izinyathelo zokupholisa ezifanele zingathathwa uma kudingeka.
(3) Ukwakhiwa kwemithombo yamavalvu. Yamukela ukwakheka okukhethekile kwesakhiwo futhi inezici zokunganakekelwa. Ngaphambi kokungcwaba, faka i-Pu ekhethekile yokulwa nokugqwala ngaphandle kwevalvu. Isiqu sevalvu seluliwe ngokufanele ngokuya ngokujula komhlabathi, ukuze abasebenzi bakwazi ukuqedela imisebenzi ehlukahlukene emhlabathini. Ngemva kokungcwaba okuqondile, kwanele ukwakha umthombo omncane wevalvu. Ngezindlela ezivamile, awukwazi ukungcwaba ngqo, futhi kudingeka kwakhiwe imithombo emikhulu yamavalvu, okuholela endaweni evaliwe eyingozi, engahambisani nokusebenza okuphephile. Ngesikhathi esifanayo, umzimba wevalvu uqobo kanye nezingxenye zokuxhumanisa i-bolt phakathi komzimba wevalvu kanye nepayipi kuzogqwala, okuzothinta impilo yesevisi yevalvu.
Yini okufanele inakwe ekunakekelweni kwevalvu yebhola ehlanganisiwe ngokugcwele?
Iphuzu liwukuthi esimweni sokuvalwa, kusekhona uketshezi olucindezelekile ngaphakathi komzimba wevalvu.
Iphuzu lesibili ukuthi ngaphambi kokulungisa, qala ukhulule ingcindezi yepayipi bese ugcina ivalvu isendaweni evulekile, bese usika umthombo wamandla noma wegesi, bese ukhipha i-actuator kusuka ku-bracket, futhi kuphela ngemva kokuba konke okungenhla sekulungisiwe.
Iphuzu lesithathu ukuthola ukuthi ingcindezi yamapayipi angenhla nangezansi kwevalvu yebhola ikhululeke ngempela, bese ukuhlukaniswa nokubola kungenziwa.
Amaphuzu amane kufanele aqaphele enkambisweni yokuqaqa nokuhlanganisa kabusha, ukuvimbela umonakalo ebusweni bokuvala izingxenye, ukusebenzisa amathuluzi akhethekile ukususa i-O-ring, nokuqinisa amabhawodi eflangeni ngokulinganayo nangokuhamba kancane nangokulinganayo ngesikhathi sokuhlanganiswa.
Amaphuzu amahlanu: Lapho kuhlanza, i-ejenti yokuhlanza esetshenziswayo kufanele ihambisane nezingxenye zerabha, izingxenye zepulasitiki, izingxenye zensimbi kanye nendawo yokusebenza ku-ball valve. Uma indawo yokusebenza iyigesi, uphethiloli ungasetshenziswa ukuhlanza izingxenye zensimbi, futhi Ezingxenyeni ezingezona ezensimbi, udinga ukusebenzisa amanzi ahlanzekile noma utshwala ukuhlanza. Izingxenye ezibolile zihlanzwa ngokucwiliswa emanzini, kanti izingxenye zensimbi zezingxenye ezingezona ezensimbi ezingakaboli zihlanzwa ngendwangu kasilika ehlanzekile necolekile efakwe ku-ejenti yokuhlanza, futhi wonke amafutha anamathele odongeni kumele asuswe. , ukungcola nothuli. Futhi, ayikwazi ukuhlanganiswa ngokushesha ngemva kokuhlanza, futhi ingenziwa kuphela ngemva kokuba i-ejenti yokuhlanza isiphelile.
