Qinisekisa ukuthi ipayipi endaweni yokufakwa kwe-i-valve yebholaisendaweni ye-coaxial, futhi ama-flange amabili epayipini kufanele agcinwe ahambisana ukuze kuqinisekiswe ukuthi ipayipi lingathwala isisindo se-valve yebhola ngokwalo.Uma kutholakala ukuthi ipayipi alikwazi ukuthwala isisindo se-valve yebhola, hlinzeka ngokusekelwa okuhambisanayo kwepayipi ngaphambi kokufakwa.
1. Qinisekisa ukulungiswa kwe-valve yebhola ngaphambi kokufakwa
1. Qinisekisa ukuthi ipayipi endaweni yokufaka i-valve yebhola isendaweni ye-coaxial, futhi ama-flange amabili epayipi kufanele agcinwe ahambisana ukuze kuqinisekiswe ukuthi ipayipi lingathwala isisindo se-valve yebhola ngokwalo.Uma kutholakala ukuthi ipayipi alikwazi ukuthwala isisindo se-valve yebhola, hlinzeka ngokusekelwa okuhambisanayo kwepayipi ngaphambi kokufakwa.
2. Qinisekisa ukuthi kukhona ukungcola, i-welding slag, njll. epayipini, futhi ipayipi kufanele ihlanzwe.
3. Hlola i-nameplate ye-valve yebhola, futhi wenze imisebenzi yokuvula ngokugcwele nokuvala ngokugcwele ku-valve yebhola izikhathi eziningana ukuze uqinisekise ukuthi i-valve ingasebenza ngokujwayelekile, bese uhlola ngokucophelela imininingwane ye-valve ukuze uqinisekise ukuthi i-valve iyasebenza. iphelele.
4. Khipha ikhava yokuvikela kuzo zombili iziphetho zevalvu, hlola ukuthi umzimba wevalvu uhlanzekile yini, bese uhlanza imbobo yomzimba.Njengoba indawo yokuvala ye-valve yebhola iyindilinga, ngisho nemfucumfucu encane ingase ibangele umonakalo endaweni yokuvala.
2. Ukufakwa kwe-valve yebhola
1. Noma iyiphi ingxenye ye-valve yebhola ingafakwa ekugcineni komfula, futhi i-valve yesibambo yebhola ingafakwa kunoma iyiphi indawo epayipini.Uma i-valve yebhola ene-actuator (njengebhokisi legiya, i-electro-pneumatic actuator) imisiwe, kufanele ifakwe iqonde, endaweni yokungena nokuphuma kwe-valve.endaweni evundlile.
2. Faka i-gasket phakathi kwe-flange ye-valve yebhola kanye ne-flange yepayipi ngokuvumelana nezidingo zokuklanywa kwepayipi.
3. Ama-bolts ku-flange kufanele aqiniswe ngokulinganayo, ngokulandelana futhi ngokulinganayo.
4. Uma i-valve yebhola ithatha i-pneumatic, kagesi nezinye i-actuator, qedela ukufakwa komthombo womoya kanye nokunikezwa kwamandla ngokuvumelana neziqondiso.
3. Ukuhlolwa ngemva kokufakwa kwe-valve yebhola
1. Ngemuva kokufakwa, qala i-valve yebhola ukuze uvule futhi uvale izikhathi eziningana.Kufanele iguquguquke futhi ifane, futhi i-valve yebhola kufanele isebenze ngokujwayelekile.
2. Ngokwezidingo zokuklama zokucindezela kwepayipi, hlola ukusebenza kokuvala kwendawo ehlangene phakathi kwe-valve yebhola kanye ne-flange yepayipi ngemva kokufakwa kwengcindezi.
Okwesine, ukugcinwa kwe-valve yebhola
1. I-valve yebhola ingahlakazwa futhi ihlakazwe kuphela ngemva kokucindezela ngaphambi nangemva kokukhishwa kwe-valve yebhola.
2. Enkambweni yokuhlakaza nokuhlanganisa kabusha i-valve yebhola, kuyadingeka ukuvikela izingxenye zokuvala, ikakhulukazi izingxenye ezingezona ezensimbi.Kungcono ukusebenzisa amathuluzi akhethekile ezingxenyeni ezifana ne-O-rings.
3. Lapho umzimba we-valve yebhola uhlanganiswa kabusha, ama-bolts kufanele aqiniswe ngokulinganayo, kancane kancane futhi ngokulinganayo.
4. I-ejenti yokuhlanza kufanele ihambisane nezingxenye zenjoloba, izingxenye zepulasitiki, izingxenye zensimbi kanye nendawo yokusebenza (njengegesi) ku-valve yebhola.Lapho indawo yokusebenza iyigesi, uphethiloli (GB484-89) ungasetshenziswa ukuhlanza izingxenye zensimbi.Hlanza izingxenye ezingezona ezensimbi ngamanzi ahlanzekile noma utshwala.
5. Izingxenye ezibolile zingahlanzwa ngokucwiliswa.Izingxenye zensimbi ezinezingxenye ezingezona ezensimbi ezingaboli zingakhuhlwa ngepompo yerotor eyomile ngendwangu ecolekile nehlanzekile efakwe i-ejenti yokuhlanza (ukuvimbela imicu ukuthi ingawi futhi inamathele ezingxenyeni).Lapho uhlanza, wonke amafutha, ukungcola, iglue, uthuli, njll okunamathela odongeni kufanele kukhishwe.
6. Izingxenye ezingezona zensimbi kufanele zisuswe ku-ejenti yokuhlanza ngokushesha ngemva kokuhlanza, futhi akufanele zifakwe isikhathi eside.
7. Ngemuva kokuhlanza, kudinga ukuqoqwa ngemuva kokuthi i-ejenti yokuhlanza odongeni ukuze igezwe iguquguquke (ingasulwa ngendwangu kasilika engazange ifakwe ku-ejenti yokuhlanza), kodwa akufanele ibanjwe. isikhathi eside, kungenjalo izogqwala futhi ingcoliswe uthuli.
8. Izingxenye ezintsha nazo zidinga ukuhlanzwa ngaphambi kokuhlanganiswa.
9. Gcoba ngamafutha.Ukugcoba kufanele kuhambisane nezinto zensimbi ze-valve yebhola, izingxenye zenjoloba, izingxenye zepulasitiki kanye nendawo yokusebenza.Lapho indawo yokusebenza iyigesi, amafutha angasetshenziswa.Gcoba ungqimba oluncane lwamafutha ebusweni bomsele wokufaka uphawu, sebenzisa ungqimba oluncane lwamafutha esigxivizweni senjoloba, bese ufaka ungqimba oluncane lwamafutha endaweni yokuvala kanye nangaphezulu kokungqubuzana kwesiqu se-valve.
10. Izinsimbi zensimbi, imicu, amafutha (ngaphandle kwalawo ashiwo ukuthi asetshenziswe), uthuli nokunye ukungcola, izinto zangaphandle akufanele zivunyelwe ukungcolisa, ukunamathela noma ukuhlala phezu kwezingxenye noma ukungena emgodini ongaphakathi ngesikhathi sokuhlanganisa.
