Ii-valve yokukhulula umoyaiyithuluzi elidingekayo lokususwa ngokushesha kwegesi epayipini, elisetshenziselwa ukuthuthukisa ukusebenza kahle kwemishini yokuhambisa amanzi nokuvikela ipayipi ekuguquguqukeni nasekuqhumeni.Ifakwe lapho kuphuma khona imbobo yepompo noma emgqeni wokuhambisa amanzi kanye nokusabalalisa ukuze kukhishwe umoya omkhulu epayipini ukuze kuthuthukiswe ukusebenza kahle kwepayipi nepompo.Uma kwenzeka kuba nomfutho ongemuhle epayipini, i-valve ingamunca ngokushesha emoyeni ukuze ivikele umonakalo odalwe ukucindezela okubi.
Lapho iphampu yamanzi iyeka ukusebenza, ukucindezela okungalungile kuzokhiqizwa nganoma yisiphi isikhathi.I-float iyawa noma nini.Esimeni sokuphuma, i-buoy idonsela phansi ingxenye eyodwa ye-lever ngenxa yesenzo samandla adonsela phansi.Ngalesi sikhathi, i-lever isesimweni sokuthambekela, futhi kukhona igebe engxenyeni yokuxhumana ye-lever kanye nembobo yokukhipha.
Umoya ukhishwa ngembobo yokungena kulesi sikhala.Ngokuphuma komoya, izinga lamanzi liyakhuphuka futhi i-buoy intanta phezulu ngaphansi kokuhamba kwamanzi.Ubuso bokuphela kokuvala ku-lever bucindezela kancane kancane imbobo ye-vent engenhla kuze kube yilapho yonke imbobo ye-vent ivinjwe ngokuphelele futhi i-valve yokukhulula umoya ivalwe ngokuphelele.
Izinyathelo zokusetha i-valve yokukhishwa komoya:
I-1.I-valve yokukhulula umoya kufanele ifakwe ngokuqondile, okungukuthi, kufanele iqinisekise ukuthi i-buoy yangaphakathi isesimweni esiqondile, ukuze ingathinti ukuphuma.
2.Lapho ii-valve yokukhulula umoyaifakiwe, kungcono ukuyifaka nge-valve yokuhlukanisa, ukuze uma i-i-valve yokukhulula umoyaidinga ukususwa ukuze ilungiswe, ingaqinisekisa ukuvala uhlelo futhi amanzi awaphumi.
3.Ii-valve yokukhulula umoyangokuvamile ifakwe endaweni ephakeme kakhulu yesistimu, ekulungele ukuthuthukisa ukusebenza kahle kwe-exhaust.
Umsebenzi we-i-valve yokukhulula umoyaikakhulukazi ukususa umoya ngaphakathi kwepayipi.Ngoba ngokuvamile kunesilinganiso esithile somoya esincibilikisiwe emanzini, futhi ukuncibilika komoya kuncipha ngokwanda kwezinga lokushisa, ngakho-ke ngesikhathi sokujikeleza kwamanzi igesi ihlukaniswa kancane kancane emanzini, futhi kancane kancane ihlangene ndawonye ukuze yenze amabhamuza amakhulu noma ngisho negesi. ikholomu, ngenxa yokwengezwa kwamanzi, ngakho-ke kuvame ukukhiqizwa kwegesi.
Isetshenziswa ngokujwayelekile ohlelweni lokufudumeza oluzimele, isistimu yokushisisa emaphakathi, i-heater boiler, i-central air conditioning, i-floor heat kanye nesistimu yokushisisa ngelanga kanye nokunye ukuphuma kwamapayipi.
Izidingo zokusebenza kwe-valve yokukhishwa komoya:
1.Ii-valve yokukhulula umoyakufanele ibe nevolumu enkulu yokukhipha umoya, futhi lapho ipayipi elingenalutho lepayipi ligcwele amanzi, lingakwazi ukubona ukuphuma ngokushesha futhi libuyisele umthamo ojwayelekile wokuphakelwa kwamanzi ngesikhathi esifushane kakhulu.
2.Lapho ii-valve yokukhulula umoyainomfutho ongemuhle epayipini, i-piston kufanele ikwazi ukuvula ngokushesha futhi ihogele inani elikhulu lomoya wangaphandle ngokushesha ukuze kuqinisekiswe ukuthi ipayipi ngeke lonakaliswe ukucindezela okungalungile.Futhi ngaphansi kwengcindezi yokusebenza, umoya wokulandela umkhondo oqoqwe epayipini ungakhishwa.
3.Ii-valve yokukhulula umoyakufanele ibe nomfutho wokuvala komoya ophezulu uma kuqhathaniswa.Esikhathini esifushane ngaphambi kokuba i-piston ivalwe, kufanele ibe namandla anele okukhipha umoya epayipini futhi ithuthukise ukusebenza kahle kokulethwa kwamanzi.
4.Ingcindezi yokuvala amanzi ye-i-valve yokukhulula umoyaakufanele kube ngaphezu kuka-0.02 MPa, kanye ne-i-valve yokukhulula umoyaingavalwa ngaphansi kwengcindezi ephansi yamanzi ukuze kugwenywe ukugeleza kwamanzi amaningi.
5.I-valve yokukhulula umoyakufanele yenziwe ngebhola lokuntanta lensimbi engagqwali (ibhakede elintantayo) njengezingxenye zokuvula nokuvala.
6.Umzimba we-valve wokukhipha umoya kufanele ufakwe isilinda sangaphakathi sokuvikela umthelela ukuvimbela ukulimala ngaphambi kwesikhathi kwebhola elintantayo (ibhakede elintantayo) okubangelwa umthelela oqondile wokugeleza kwamanzi ngesivinini esiphezulu kwibhola elintantayo (ibhakede elintantayo) ngemuva kokukhipha okuningi.
7.Okwe-DN≥100i-valve yokukhulula umoya, isakhiwo sokuhlukaniswa siyamukelwa, esakhiwe ngenani elikhului-valve yokukhulula umoyafuthii-automatic air release valveukuhlangabezana nezidingo zokucindezela kwepayipi.Ii-automatic air release valvekufanele isebenzise indlela ye-lever ephindwe kabili ukuze ikhulise kakhulu ukuhamba kwebhola elintantayo, futhi izinga lamanzi lokuvala liphansi.Ukungcola emanzini akulula ukuthintana nendawo yokubeka uphawu, futhi i-port yokukhipha ngeke ivinjwe, futhi ukusebenza kwayo kokuvimbela ukuvimbela kungathuthukiswa kakhulu.
Ngesikhathi esifanayo, ngaphansi kwengcindezi ephakeme, ngenxa yomphumela we-lever ehlanganisiwe, i-float ingakwazi ukwehla ngokuhambisana nezinga lamanzi, futhi izingxenye zokuvula nokuvala ngeke zimunywe ukucindezela okukhulu njengama-valve endabuko, ukuze kukhishwe ngokujwayelekile. .
8. Ezimweni ezinezinga eliphezulu lokugeleza, ukuqala njalo kwepompo yamanzi nobubanzi DN≧100, i-buffer plug valve kufanele ifakwei-valve yokukhulula umoyaukuze unciphise umthelela wamanzi.I-valve yepulaki ye-buffer kufanele ikwazi ukuvimbela inani elikhulu lamanzi ngaphandle kokuphazamisa inani elikhulu lokukhipha umoya, ukuze ukusebenza kahle kokulethwa kwamanzi kungeke kuthinteke, futhi kuvimbele ngokuphumelelayo ukwenzeka kwesando samanzi.
