Lapho ufaka i-valve yesango, ukuze uvimbele izinto zangaphandle njengensimbi nesihlabathi ukuthi zingangeni ku-valve yesango futhi zilimaze indawo yokuvala;kuyadingeka ukusetha isihlungi kanye ne-valve yokushaya.Ukuze ugcine umoya ocindezelwe uhlanzekile, isihlukanisi samanzi samafutha noma isihlungi somoya kufanele sifakwe ngaphambi kwe-valve yesango.Uma kucatshangelwa ukuthi isimo sokusebenza se-valve yesango singabhekwa ngesikhathi sokusebenza, kuyadingeka ukusetha izinsimbi nokuhlola ama-valve.
Umkhiqizi we-valve wesango uthe ukuze kugcinwe izinga lokushisa lokusebenza, izikhungo zokushisa ezishisayo zifakwe ngaphandle kwe-valve yesango;ukufakwa ngemuva kwe-valve, i-valve yokuphepha noma i-valve yokuhlola idinga ukusetha;ngokucabangela ukusebenza okuqhubekayo kwe-valve yesango, okuyinto elula futhi eyingozi, uhlelo oluhambisanayo noma uhlelo lwe-bypass lusethiwe.
1. Hlola izindawo zokuvikela i-valve yesango:
I-valve yokuvala eyodwa noma amabili afakwe ngaphambi nangemva kwe-valve yokuhlola ukuze kuvinjelwe ukuwohloka kwekhwalithi yomkhiqizo, izingozi kanye neminye imiphumela emibi ebangelwa ukuvuza noma ukugeleza okuphakathi emuva ngemva kokwehluleka kwe-valve yokuhlola.I-valve yokuhlola ingasuswa kalula futhi iseviswe uma i-valve yokuvala emibili inikezwa.
2. Ukuqaliswa kokuvikelwa kwe-valve yokuphepha
I-valve yokuvala ngokuvamile ayisethwa ngaphambi nangemuva kwendlela yokufaka, futhi ingasetshenziswa kuphela ezimweni ezingazodwana.Khumbuza wonke umuntu ukuthi uma amandla aphakathi nendawo equkethe izinhlayiya eziqinile, izophazamisa ivalvu yokuphepha ekukhiyeni ngemva kokusuka.Ngakho-ke, i-valve yesango evalwe ngomthofu kufanele ifakwe ngaphambi nangemva kwe-valve yokuphepha.Amavalvu esango kanye nokuphepha kufanele avuleke ngokugcwele futhi i-valve yokuhlola i-DN20 emkhathini kufanele ifakwe ngokuqondile.Abakhiqizi be-valve yesango
Umkhiqizi we-valve yesango uthe ekushiseni okuvamile, lapho okuphakathi okufana ne-wax ekhishwa kancane kuqinile, noma lapho izinga lokushisa lokufakwa kwe-gasification loketshezi olukhanyayo nokunye okuphakathi liphansi kuno-0 ngenxa yokuwohloka, ukulandelwa kwe-steam kuyadingeka.Uma kuyi-valve yokuphepha esetshenziselwa i-corrosion medium, ngakho-ke ngokusho kokumelana nokugqwala kwe-valve yesango, kuyadingeka ukwengeza ifilimu evimbela ukugqwala ekuqhumeni emnyango we-valve yesango.Imvamisa, amavalvu okuphepha kwegesi afakwe i-bypass valve ukuze kungene umoya ngesandla kuye ngosayizi wawo.
3. Izinsiza zokuvikela ze-valve yokunciphisa ingcindezi:
Ngokuvamile kunezinhlobo ezintathu zezikhungo zokufaka ama-valve okunciphisa ingcindezi.Ama-gauge okucindezela afakwe ngaphambi nangemva kwe-valve yokunciphisa ingcindezi, okulula ukubuka ingcindezi ngaphambi nangemva kwe-valve.Faka i-valve yokuphepha evalwe ngokugcwele ngemuva kwe-valve yesango ukuvimbela ukwehluleka kwe-valve yesango.Lapho ingcindezi ngemuva kwe-valve idlula ingcindezi evamile, uhlelo olungemuva kwe-valve luyagxuma.Abakhiqizi be-valve yesango
Ipayipi lokukhipha amanzi lifakwe phambi kwevalve yokuvala phambi kwe-valve yesango, futhi isetshenziselwa ikakhulukazi ukudonsa umzila wokudonsa amanzi.Abanye babo basebenzisa izicupho ze-steam.Ipayipi le-bypass lisetshenziselwa ikakhulukazi ukuvala i-valve yokuvala, ukuvula i-valve ye-bypass, futhi ulungise ngesandla ukugeleza ngaphambi nangemva kokuhluleka kwe-valve yokunciphisa ingcindezi.Ingaqhutshwa ngebhayisikili bese kulungiswa ivalvu yokukhulula noma ishintshwe.
4. Izinsiza zokuvikela izicupho zesitimu:
Umkhiqizi wamavalvu esango uthe kunezinhlobo ezimbili zezicupho ezinamapayipi adlulayo nangenawo, okuhlanganisa izicupho ezinezidingo ezikhethekile njengokubuyiswa kwe-condensate, ukungabuki kwe-condensate, kanye nezindleko zokukhipha amanzi.Ingafakwa ngokuhambisana.Onjiniyela bethu bakukhumbuza ukuthi lapho useva izicupho, ungakhiphi i-condensate ngomugqa wokudlula, okuzovumela isitimu ukubaleka futhi sibuyele ohlelweni lwamanzi.Ngaphansi kwezimo ezijwayelekile, asikho isidingo sokufaka ipayipi ye-bypass, futhi ifaneleka kuphela imishini yokushisa enezidingo zokushisa eziqinile zokushisa ekukhiqizeni okuqhubekayo.
