Kwiinkqubo zokukhusela umlilo,Iivalvu ze-OS&Y(Iivalufa zeSkruf kunye neYoke zangaphandle) zizinto ezibalulekileyo ezisetyenziselwa ukulawula ukuhamba kwamanzi, igwebu, okanye ezinye izinto zokucima umlilo ngokusebenzisa iinkqubo zemibhobho. Ezi valufa zixhaphake kakhulu kwiinkqubo zokutshiza kunye neenkqubo zemibhobho ezimiyo ezenzelwe ukukhusela izakhiwo kunye neziseko zophuhliso kumonakalo womlilo. Kwesi sikhokelo, siza kuhlola indima ebalulekileyoIivalvu ze-OS&Y, ukusebenza kwazo, kunye nesizathu sokuba zibalulekile ekukhuseleni umlilo.
1. Yintoni iValve ye-OS&Y
Ivalvu ye-OS&Y luhlobo lwevalvu yesango esetyenziswa kakhulu kwiinkqubo zokukhusela umlilo. Igama elithi OS&Y limele "iScrew and Yoke yangaphandle," elibhekisa kulwakhiwo lwesiqu sevalvu, isikrufu, kunye nokuhlanganiswa kwejoko. Ivalvu yenzelwe ukubonelela ngendlela ethembekileyo nebonakalayo yokuvala okanye yokulawula ukuhamba kwamanzi kwiindawo ezibalulekileyo zokukhusela umlilo, njengeenkqubo zokucima umlilo okanye iinkqubo zokutshiza.
Isikrufu singaphandle komzimba wevalvu, sinamathele kwijoko ebamba isiqu.
Njengoko ivalvu isebenza, isiqu siya phezulu nasezantsi ngaphakathi kwidyokhwe, siphakamisa okanye sihlisa isango ngaphakathi komzimba wevalvu.
Isalathisi esibonakalayo (isiqu) esingaphandle komzimba wevalvu sivumela abaqhubi ukuba babone imeko yevalvu ngokujonga nje, oko kukuthi, nokuba ivuliwe okanye ivaliwe.
2.NjaniIivalvu ze-OS&YUmsebenzi
Iivalvu ze-OS&YZidla ngokuba zezezandla, oko kuthetha ukuba zifuna ukwenziwa ngesandla ukuze zivuleke okanye zivale. Ivalvu isebenza ngokujika ivili okanye ivili lesandla, elijikeleza isiqu. Njengoko ivili lijika, isikrufu emzimbeni wevalvu sishukumisa idyokhwe, siphakamise okanye sehlise isango elingaphakathi kwevalvu. Xa ivalvu ivuliwe, amanzi ahamba ngokukhululekileyo kwinkqubo, kwaye xa ivaliwe, ukuhamba kwamanzi kuvaliwe ngokupheleleyo.
3. Kutheni UsebenzisaIivalvu ze-OS&YkwiiNkqubo zoKhuseleko loMlilo
Ukubonakala kwesimo seValve: Enye yezona zinto zibalulekileyoIivalvu ze-OS&Yluphawu olubonakalayo olubonisa ukuba ivalvu ivuliwe okanye ivaliwe. Olu phawu lubaluleke kakhulu kwiinkqubo zokukhusela umlilo, apho ukwenza izigqibo ngokukhawuleza kunokusindisa ubomi kunye nepropathi. Kwimeko engxamisekileyo, umcimi-mlilo okanye ingcali yokulungisa unokuchonga ngokukhawuleza ukuba ivalvu ivuliwe na, ukuqinisekisa ukuba akukho kulibaziseka ekusebenzeni kwenkqubo yokucima umlilo.
Ukusebenza okuthembekileyo:Iivalvu ze-OS&YZithembeke kakhulu ekulawuleni ukuhamba kwamanzi, kwaye zenzelwe ukusebenza ngokufanelekileyo phantsi kweemeko ezinzima, njengeenkqubo zoxinzelelo oluphezulu ezisetyenziswa ekukhuseleni umlilo. Uyilo lwazo oluqinileyo luzivumela ukuba zikwazi ukumelana neemeko ezinzima kwaye zisebenze ngokuchanekileyo, nto leyo ebalulekileyo ekuthembekeni kwenkqubo yonke yokukhusela umlilo.
Ukulungiswa okulula: Ngenxa yoyilo lwabo olulula nolucacileyo,Iivalvu ze-OS&YKulula ukuzilungisa nokuzilungisa. Uyilo oluvulekileyo lwevalvu luvumela ukuhlolwa ngokukhawuleza kwezinto ezibalulekileyo ezifana nesiqu, ijoko, kunye nesango. Ukongeza, ezi valve azifuni lubrication eninzi, nto leyo enciphisa ngakumbi isidingo sokugcinwa rhoqo.
Ukuthintela ukuvuza:Iivalvu ze-OS&Yzenzelwe ukubonelela ngokuvala okuqinileyo xa zivaliwe. Oku kuthintela ukuvuza, okunokuphazamisa ukusebenza kakuhle kwenkqubo yokukhusela umlilo. Nokuba ivalvu iyinxalenye yenkqubo yemibhobho emileyo, inkqubo yokutshiza, okanye i-fire hydrant, ukuqinisekisa ukuba akukho kuvuza kubalulekile ukuqinisekisa ukuba amanzi ayafumaneka xa kutsha.
Ukumelana nokugqwala: Ngenxa yokubaluleka kweenkqubo zokukhusela umlilo,Iivalvu ze-OS&Yzihlala zenziwe ngezinto ezikumgangatho ophezulu ezifana nebronzi, ibronzi, okanye intsimbi engatyiwayo. Ezi zinto zibonelela ngokumelana okuhle nokugqwala, ziqinisekisa ukuba iivalvu zisebenza kakuhle nakwiindawo ezinomswakama ophezulu okanye ukuvezwa emanzini.
4. Iingenelo zeIivalvu ze-OS&Ykwiinkqubo zokukhusela umlilo
Ukuthembeka Nokuqina:Iivalvu ze-OS&Yzenzelwe ukunyamezela iimeko ezinzima, ukuqinisekisa ukuthembeka nokuqina kwexesha elide.
Ukulula Kokusebenza: Zisebenza ngesandla, nto leyo eyenza kube lula ukuzisebenzisa nokuzilungiselela.
Izalathisi zeMeko ecacileyo: Isiqu esibonakalayo sibonisa ngokucacileyo indawo yevalvu, kunciphisa amathuba okwenza iimpazamo kwiimeko ezingxamisekileyo.
Iimfuno Ezincinci Zokugcinwa: Ezi valve azifuni ukugcinwa okuninzi kwaye kulula ukuzilungisa xa zifuneka.
5.Ukukhetha iValve ye-OS&Y efanelekileyo yeNkqubo yakho yoKhuseleko loMlilo
Ubungakanani: Ubungakanani bevalvu kufuneka buhambelane nobukhulu benkqubo yemibhobho ukuqinisekisa ukuhamba kwamanzi kunye noxinzelelo olufanelekileyo.
Izinto ezisetyenzisiweyo: Khetha izinto ezifanelekileyo (ezifana nobhedu, ubhedu, okanye intsimbi engatyiwayo) ukuqinisekisa ukuba ziyamelana nokugqwala kwaye zihlala ixesha elide, ingakumbi kwiindawo apho amanzi kunye nokufuma kuxhaphakileyo.
Uvavanyo loxinzelelo: Qinisekisa ukuba ivalvu ilinganiswe ngoxinzelelo olungaphakathi kwenkqubo ukuze kuthintelwe ukuvuza okanye ukungaphumeleli.
Imithetho Yengingqi: Qaphela imithetho yomlilo yengingqi kunye nemigaqo, enokuthi ichaze uhlobo lweevalvu ezifunekayo kwiintlobo ezithile zeenkqubo.
