Iinkqubo zokulwa umliloKubalulekile ukukhusela ubomi kunye nepropathi kwimeko yomlilo. Elinye lawona macandelo aphambili kwezi nkqubo yivalve yesango, elawula ukuhamba kwamanzi kwinethiwekhi yenethiwekhi. Phakathi kweentlobo ezahlukeneyo zedonga lesango, isiqu sokunyuka(NRS) I-Palve yesangolukhetho olukhethwayo kwizifako ezininzi. Uyilo lwayo olukhethekileyo lwenza ukuba lubekwe ngokukhethekileyo kwizicelo ezithile, ngakumbi apho indawo inyanzelekile okanye ikwimeko yokusingqongileyo. Kweli nqaku, siza kuyifaka kwinkcazo, iimpawu, izibonelelo, kunye nokusetyenziswa kwesango lesango le-NRS kwiinkqubo zokulwa umlilo.
Inkcazo ye-NRS ye-NRS
I-NRS (i-steting stem) ye-valve yesango luhlobo lwe-valve yesango apho isiqu singahambi ngokuthe nkqo njengoko ivalve ivuliwe okanye ivaliwe. Endaweni yoko, isango okanye umtshato ngaphakathi kwi-valve sinyuka siye ezantsi ukulawula ukuhamba kwamanzi, ngelixa isiqu sihlala sikwisikhundla esimisiweyo. Ukujikeleziswa kwesiqu, kusetyenziswa i-handheel, ukuqhubela phambili ukuhamba kwesango.
Olo hluko loyilo luhamba nge-valves yesango, apho i-stem ngokubonakala ihambahamba okanye ezantsi njengoko ivalve isebenza. Ngokugcina i-story story, i-ns yesango ye-NRS inika i-compact and fact yoyilo elilungele iindawo ezinokunqongophala kwendawo okanye apho intshukumo ye-stem yangaphandle inokuphazamisa ukusebenza.
Iimpawu eziphambili ze-NRS
1.Uyilo olugcina indawo
Isimo se-stem sesango leSango le-NRS IVOVE iqinisekisa ukuba incinci indawo ethe nkqo. Oku kwenza ukuba ilungele ukufakelwa kwiinkqubo eziphantsi komhlaba, amagumbi okusebenza, okanye nayiphi na indawo apho indawo iyiprimiyamu.
2.Ifakwe isiqendu sokukhusela
Isiqu sivalwe ngaphakathi kwi-vanven, siyikhusela kwizinto ezizesingqongileyo ezinje ngobumdaka, ubushushu, okanye izixhobo ezinobunkunkqele. Lowo uyila uqhotyoshelweyo uqinisekisa ukusebenza ngokuthembekileyo ngexesha elongezelelekileyo, nkqu nakwiimeko ezinzima.
3.Isalathiso sesikhundla
Kuba isiqu singaphumi, uninzi lwesango le-NRS luxhotywe ngesalathiso sesikhundla kwi-valve okanye i-activator ukubonisa ukuba ivalve ivuliwe okanye ivaliwe. Eli linqaku elibalulekileyo leenkqubo zokulwa imililo, njengoko ivumela ukuqinisekiswa okukhawulezayo kwe-vali ngexesha likaxakeka ngexesha likaxakeka okanye uhlolo lwendlela.
4.Ukuqina kwempahla
I-NRS yesango isetyenziswa kwiinkqubo zokulwa umlilo zihlala zakhiwa kwizinto ezomeleleyo ezinjengesinyithi, intsimbi engenasigaba, okanye ibronze. Ezi zixhobo zibonelela ngokuchasene nokunganyangeki kakuhle, kuqinisekisa ukuthembeka kwexesha elide kwiindawo ezinamanzi okanye ezonakalisayo.
5.Ukusebenza kakuhle phantsi koxinzelelo oluphezulu
Iinkqubo zokulwa imililo zihlala zibandakanya uxinzelelo lwamanzi aphezulu, kunye ne-valve yesango i-NRS ezenziweyo ukuze zisingise iimeko ezinjalo. Umsebenzi wabo ogudileyo kukunciphisa ukuxhathisa kwaye kuqinisekisa ukuhanjiswa kwamanzi okusebenzayo ngexesha lokucima umlilo.
Izicelo ze-valve zesango zeNks kwiNkqubo yokuBinisa imililo
I-valve yesango ye-NRS idlala indima ebalulekileyo kwiinkalo ezahlukeneyo zokulwa umlilo, kubandakanya:
1. Ulawulo lwamanzi aphambili
I-valve yesango ye-NRS ifakwe kwi-valves yesango ephambili yokuhambisa amanzi ngeenkqubo zokulwa komlilo ukulawula ukuhamba kwamanzi ukuya kwizinto zokuma, ii-hydds, kunye neenkqubo ze-sprinkler. Bavumela abacimi-mlilo ukuba bakwazi ukwahlula amacandelo enkqubo okanye bathumele amanzi kwakhona njengoko kufuneka.
2. Ukufakelwa phantsi komhlaba
Ngenxa yoyilo lwabo lwe-Compact, i-NRS yesango isetyenziswa rhoqo kwiinkqubo eziphambili zomlilo eziphantsi komhlaba. Uyilo lwe-sth elivalelweyo luthintele umonakalo ovela kumhlaba, inkunkuma, okanye i-ingeress yamanzi, ukuqinisekisa ukusebenza okuthembekileyo ngokuhamba kwexesha.
3. Iinkqubo zokuma kunye ne-spinkler
Kwiinkqubo zokuma, i-NRS yesango ilawula ukuhamba kwamanzi kwiindawo ezahlukeneyo okanye imigangatho yesakhiwo. Ngokufanayo, kwiinkqubo ze-spinkler, ezi valves zivumela ukwahlukana okuthile, ukuqhubela phambili ukugcinwa okanye ukulungiswa ngaphandle kokuphazamisa yonke inkqubo.
4. Unxibelelwano lomlilo
I-valve yesango ze-NRS zihlala zisetyenziselwa ukulawula ukubonelela ngamanzi kwi-chydrants yomlilo. Uyilo lwabo lwe-compact kunye nolomeleleyo lubenza balungele zombini ukufakelwa kwe-hydrant hyddrant.
5. Izixhobo ezinkulu zemveliso okanye zorhwebo
Iindawo zokugcina izinto, iifektri, kunye nezinye iindawo ezinkulu zixhomekeke kwi-valve yesango ye-NRS zokulawula ukuhamba kwamanzi kwiinkqubo zabo zokukhusela umlilo. Ezi valve zibonelela ngokuqina kunye nokusebenza ngokukuko kwiindawo apho ukusebenza kobhono kubalulekile.
IINGOZI ZOKUGQIBELA ZALWROS KWI-POLDS KWI-STALM YOKUGQIBELA
Ukuthandwa kwee-valve zesango ze-NRS kwiinkqubo zokulwa komlilo zinokuchazwa kwiinzuzo ezininzi:
lUkusebenza kwendawo: Uyilo lwe-sth lonyukayo lulungele i-compact okanye ufakelo oluphantsi komhlaba.
lUkulungiswa kwesondlo: Uyilo lwe-STE evalelweyo linciphisa ukuvezwa kwenkunkuma, ukunciphisa isidingo sokucoca rhoqo okanye ukulungiswa.
lUkusebenza ngendleko: Izinto ezihlala ixesha elide kunye neemfuno zolondolozo eziphantsi zikhokelela kwiindleko ezisezantsi zobomi.
lUkuchongwa kweSikhundla esikhawulezayo: Izalathisi zibonelela ngesalathiso esicacileyo sokuba ivalve ivuliwe okanye ivaliwe.
lUkuhambelana noxinzelelo oluphezulu: Yenzelwe ukwenza ngokuthembekileyo kwiinkqubo ezinexinzelelo oluphezulu lwamanzi, ukuqinisekisa ukucinezelwa komlilo.
Ukulungiswa kunye nokuhlolwa
Ukulungiswa rhoqo kubalulekile ukuqinisekisa ukusebenza kunye nokuthembeka kweebhova zesango ze-NRS kwiinkqubo zokulwa umlilo. Ezi zinto zilandelayo kufuneka zibe yinxalenye yenkqubo yesondlo:
1.Uvavanyo olubonakalayo
Jonga i-valve ye-valve kunye nesalathiso sesikhundla semiqondiso yokunxiba, ukusulelwa, okanye ukonakala. Qinisekisa ivalve ifakwe ngokucacileyo kwaye ifikeleleke.
2.Uvavanyo lokusebenza
Ngamaxesha athile uvule kwaye uvale i-valve ukuqinisekisa ukusebenza kakuhle kunye nokutywinwa ngendlela efanelekileyo. Qinisekisa ukuba isalathiso sesikhundla sibonisa ngokuchanekileyo imeko yevali.
3.Ukuvavanywa koxinzelelo
Vavanya ivalve phantsi koxinzelelo lwenkqubo ukuqinisekisa amandla ayo okumelana nokulawula iimeko zoxinzelelo oluphezulu ngaphandle kokuvuza okanye ukungasebenzi kakuhle.
4.I-Lubrication
Faka isicelo se-phumela kwi-valve stem kunye nezinto zangaphakathi njengoko kucetyiswa ngumenzi ukuqinisekisa intsebenzo efanelekileyo.
5.Ukutshintshwa kwezinto ezinxibe
Faka endaweni yazo naziphi na iinxalenye ezonakalisiweyo okanye ezonakeleyo, ezinjengamatywina, i-galls, okanye isalathiso sendawo, ukugcina intsebenzo kunye nokhuseleko lwevali.
Ukuqukumbela
I-NRSRUVE yesango licandelo elibalulekileyo leenkqubo zokulwa umlilo, ukubonelela ngolawulo lokuhamba kwamanzi okusebenzayo kwizicelo ezahlukeneyo. Uyilo lwecawe, ulwakhiwo oluhlala luhleli, kunye nokukhululeka kuyenza ukhetho olufanelekileyo lokufakelwa phantsi komhlaba, iinkqubo zokutshiza, kunye namaxabiso omlilo. Ngokuthobela iindlela ezifanelekileyo zokufakelwa kunye nokuqhuba ulondolozo rhoqo, i-valve yesango ye-NRS iqinisekisa ukusebenza ixesha elide kunye negalelo elibonakalayo kukhuseleko kunye nokuthembeka kweenkqubo zokukhusela umlilo.
Kuyo nayiphi na inkqubo yokulwa umlilo, ukukhetha ivalve efanelekileyo kubalulekile ukukhusela ubomi kunye nepropathi, kunye ne-valve yesango ye-NRS iyaqhubeka isisombululo esithembileyo kwicandelo lokhuseleko lomlilo.
