Amavalvu okuphephazidlala indima ebalulekile ekuvikeleni izinhlelo zokucindezela ezimweni zokucindezela ngokweqile. Lapho ingcindezi ikhuphuka ngaphezu komkhawulo ophephile, ivalvu yokuphepha ivuleka ngokuzenzakalelayo ukuze ikhulule ingcindezi eyengeziwe, isize ekuvimbeleni umonakalo wemishini, ukwehluleka kohlelo, noma izingozi ezinkulu. Ngenxa yokuthi izinhlelo zokucindezela ziyahlukahluka kakhulu kuzo zonke izimboni, amavalvu okuphepha eza ngezinhlobo eziningana, ngayinye yenzelwe izimo zokusebenza ezithile kanye nemidiya.
1. Ivalvu Yokuphepha Egcwele Intwasahlobo
Ivalvu yokuphepha efakwe entwasahlobo iyindlela esetshenziswa kakhulu kuzo zonke izinhlelo zokusebenza zezimboni.
Isiphethu esilinganisiwe sigcina ivalvu ivaliwe ngaphansi kwengcindezi evamile. Uma ingcindezi yesistimu idlula iphuzu elibekiwe, amandla anqoba isiphethu bese ivalvu ivuleka. Uma ingcindezi isibuyele ezingeni eliphephile, ivalvu ivala ngokuzenzakalelayo.
Izici ezibalulekile:Isakhiwo esilula.Ithembekile futhi ingabizi kakhulu.Impendulo esheshayo ekucindezelekeni ngokweqile
Izinhlelo zokusebenza ezijwayelekile:Ama-boiler omusi, imikhumbi yokucindezela, izinhlelo zomoya ocindezelwe, amapayipi kawoyela negesi, izinhlelo ezisizayo zasolwandle.
2. Ivalvu Yokuphepha Eqhutshwa Yibhanoyi
Amavalvu okuphepha aqhutshwa yi-pilot asebenzisa ingcindezi yesistimu ukulawula ukuvulwa nokuvalwa kwevalvu eyinhloko ngevalvu encane ye-pilot.
Uma ingcindezi ifika endaweni ebekiwe, ivalvu yokushayela iyavuleka kuqala, okubangela ukungalingani kwengcindezi okuvula ivalvu eyinhloko. Lo mklamo uvumela ukulawulwa kwengcindezi okunembile ngokuvuza okuncane ngaphansi kwezimo ezijwayelekile.
Izici ezibalulekile:Ukunemba okuphezulu kwengcindezi yokusetha.Ifanele izinhlelo ezinomfutho ophezulu.Ukuvuza kwesihlalo okuncishisiwe
Izinhlelo zokusebenza ezijwayelekile:Izinhlelo zegesi ezinomfutho ophezulu, izindawo zokuhluza, iziteshi zikagesi, imikhumbi yokucindezela enamandla amakhulu.
3. I-Balanced Bellows Safety Valve
Amavalvu okuphepha e-bellows alinganisiwe aklanyelwe ukunciphisa ithonya lokucindezeleka komhlane ekusebenzeni kwamavalvu.
I-bellow yensimbi ihlukanisa indawo yesipilingi kanye nebhonethi ekucindezelekeni okuphansi komfula. Lokhu kusiza ukugcina ingcindezi eqinile ngisho nalapho ingcindezi yangemuva ishintshashintsha.
Izici ezibalulekile:Ukusebenza okuzinzile ngaphansi kwengcindezi eguquguqukayo yangemuva.Ukusebenza kokuvala okuthuthukisiwe.Umphumela oncishisiwe wezimo ezingezansi komfula
Izinhlelo zokusebenza ezijwayelekile:Ukucubungula amakhemikhali, izinhlelo zomusi ezinepayipi lokukhipha amanzi isikhathi eside, izinhlelo zokukhipha umoya olwandle kanye nezinhlelo zokungenisa umoya.
4. I-Valve Yokuphepha Ejwayelekile
I-valve yokuphepha evamile incike ngqo ekucindezelweni kwesistimu okusebenza kudiski ye-valve ukuvula i-valve.
Nakuba ilula futhi ihlala isikhathi eside, ukusebenza kwayo kungathinteka yingcindezi yangemuva emgqeni wokukhipha. Ngenxa yalesi sizathu, isetshenziswa kangcono lapho ingcindezi yangemuva iphansi noma izinzile.
Izici ezibalulekile:Idizayini elula.Ukulungiswa okulula.Izindleko eziphansi
Izinhlelo zokusebenza ezijwayelekile:Ama-boiler anomfutho ophansi, izinhlelo zamanzi, izinhlelo zokunciphisa umfutho ezingabalulekile.
5. I-Valve Yokusiza Ukuphepha
Ivalvu yokusiza ukuphepha ihlanganisa imisebenzi yevalvu yokuphepha kanye nevalvu yokusiza ekwakhiweni okukodwa.
Ingaphatha kokubili uketshezi olucindezelwayo, njengegesi noma umusi, kanye noketshezi olungacindezelwayo, njengoketshezi. Ivalvu ivuleka kancane kancane noma ngokushesha kuye ngokukhuphuka kwengcindezi.
Izici ezibalulekile:Ukusebenza okuguquguqukayo.Ifanelekela imidiya exubile.Ukukhishwa kwengcindezi okubushelelezi
Izinhlelo zokusebenza ezijwayelekile:Izinhlelo zikawoyela negesi, izitshalo zamakhemikhali, izinhlelo zikaphethiloli zasolwandle kanye nokugcoba.
6. Amavalvu Okuphepha Aphansi Naphezulu Kakhulu
Ama-valve okuphepha nawo ahlukaniswa ngokuthi i-disc iphakamisa ibanga elingakanani ngesikhathi sokusebenza.
A ivalvu yokuphepha ephansiIvula ibanga elincane kuphela futhi ifanelekela izinsizakalo zoketshezi.
A ivalvu yokuphepha egcweleIvula ngokugcwele cishe ngokushesha futhi ilungele igesi noma umusi.
Izinhlelo zokusebenza ezijwayelekile
-
①I-Low-lift: amapayipi oketshezi, izinhlelo ze-hydraulic
-
②Full-lift: ama-steam boilers, izinhlelo zegesi, imikhumbi yokucindezela
Kungani Kubalulekile Ukukhetha I-Valve Yokuphepha Efanele
Uhlobo ngalunye lwe-valve yokuphepha lusabela ngendlela ehlukile ekucindezelweni, ezokuxhumana, izinga lokushisa, kanye nokucindezeleka kwangemuva. Ukusebenzisa uhlobo olungalungile kungaholela ekusebenzeni okungazinzile, ukuvuza, noma ukukhululeka okunganele kwengcindezi. Ukukhetha kahle kuthuthukisa ukuphepha kohlelo, kwandisa isikhathi sokuphila kwemishini, futhi kuqinisekisa ukuhambisana nezindinganiso zomhlaba wonke.
