Zinceda ekuthinteleni uxinezeleko olugqithisileyo, ngoko ke inkqubo isebenza xa kufuneka.Ivalvu Yokunciphisa Uxinzelelo Lwamanzi, I-Motorized Pressure Reducing ValvekunyeIvalvu Yokunciphisa Uxinzelelo LweeMechanicalzonke zixhasa ukuthotyelwa kwemigangatho yokhuseleko lomlilo ngokuhlola nokulungisa rhoqo.
Uhlobo lweValve yokunciphisa uxinzelelo E: Imisebenzi yokuthobela imithetho
Injongo kunye nokuSebenza
IUhlobo lwevalvu yokunciphisa uxinzelelo EIdlala indima enkulu kwiinkqubo zokukhusela umlilo. Igcina uxinzelelo lwamanzi lukwinqanaba elikhuselekileyo, ngoko ke imibhobho kunye neepayipi azidubuli ngexesha likaxakeka. Le valve isebenza ngokulungelelanisa ukuhamba kwamanzi ukusuka kwindawo ephambili yokuhambisa amanzi. Xa uxinzelelo lokungena lutshintsha, ivalvu ivula okanye ivale ngokuzenzekelayo ukugcina uxinzelelo lokukhupha luzinzile. Abacimi-mlilo banokuthembela kumjelo wamanzi othembekileyo, nokuba uxinzelelo olukwinkqubo luya phezulu okanye luhla. Umzimba wobhedu oqinileyo wevalvu unokusingatha uxinzelelo oluphezulu, ukuya kuthi ga kwi-30 bar, kwaye ingena ngokulula kwiintlobo ezininzi zeenkqubo zokucima umlilo. Abantu badla ngokubona ezi valve kwiindawo ezifana nezibhedlele, iivenkile ezinkulu, kunye nezakhiwo ezinde. Zinceda ekukhuseleni izixhobo ekonakaleni kwaye ziqinisekisa ukuba amanzi ahlala elungile xa kufuneka.
Iimpawu eziphambili ezixhasa iMigangatho yoKhuseleko loMlilo
Uhlobo lwevalvu yokunciphisa uxinzelelo E luza neempawu ezinceda ekuhlangabezaneni nemithetho engqongqo yokhuseleko lomlilo.iqinisekisiwe kwi-BS 5041 Icandelo 1 kunye ne-ISO 9001:2015, ebonisa ukuba iyahlangabezana nemigangatho yokhuseleko lwehlabathi. Ivalvu inokulungisa uxinzelelo lwe-outlet phakathi kweebha ezi-5 nezi-8, nto leyo ibalulekileyo kwiimfuno ezahlukeneyo zesakhiwo. Uyilo lwayo luvumela ukufakwa ngokukhawuleza kunye nokugcinwa lula. Ivalvu ikwaxhasa izinga eliphezulu lokuhamba kwamanzi, ukuya kuthi ga kwiilitha ezili-1400 ngomzuzu, nto leyo enceda abacimi-mlilo ukulawula imililo ngokukhawuleza. Kwizakhiwo eziphakamileyo, le valve ivumela iinjineli ukuba zibeke uxinzelelo olufanelekileyo kumgangatho ngamnye, ziqinisekisa ukuba yonke ipayipi ifumana amanzi aneleyo. Ezi mpawu zinceda ukuthintela ukusilela kwenkqubo kwaye zigcine abantu kunye nempahla bekhuselekile ngexesha lomlilo.
Imigangatho yokunciphisa uxinzelelo kunye nemigangatho yokhuseleko lomlilo
Iikhowudi kunye neMigangatho efanelekileyo (NFPA, IBC, BS 5041)
Iikhowudi zokhuseleko lomlilo zibeka imithetho yendlela izakhiwo ezikhusela ngayo abantu kunye nempahla emlilweni. Uhlobo lweValve E yokunciphisa uxinzelelo lunceda ukuhlangabezana nale mithetho ngokulawula uxinzelelo lwamanzi kwiinkqubo ze-fire hydrant. Amazwe ahlukeneyo kunye nemimandla isebenzisa imigangatho yawo, kodwa uninzi lulandela izikhokelo ezivela kumaqela afana ne-NFPA, i-IBC, kunye ne-BS 5041.
Nantsi ingqwalasela emfutshane yendlela le migangatho ethelekiswa ngayo:
| Umgangatho | Imfuneko Ephambili | Amanqaku Akhethekileyo |
|---|---|---|
| I-NFPA 20 | Ii-PRV ziyafuneka kwiimpompo zedizili ukuba uxinzelelo ludlula umlinganiselo | Iimpompo zombane zifuna ii-PRV kuphela ezinee-drivers zesantya esiguquguqukayo |
| I-NFPA 13 kunye ne-14 | Iivalvu zokulawula uxinzelelo kufuneka zigcine uqhagamshelo lwepayipi lungaphantsi kwe-175 psi | Iivalvu ezahlukeneyo zeeklasi ezahlukeneyo zepayipi ziyavunyelwa |
| I-BS 5041 | Iivalvu kufuneka ziphumelele uvavanyo lokuhamba kwamanzi kunye noxinzelelo | Igxile ekwakhiweni kweevalvu kunye nokuqina kwazo |
| I-IBC | Ilandela i-NFPA kunye neekhowudi zasekuhlaleni zokukhusela umlilo | Ilungelelanisa ubude besakhiwo kunye noyilo lwenkqubo |
Icebiso: Imigangatho yamazwe ngamazwe inokubeka imida eyahlukeneyo yoxinzelelo kunye nemithetho yokufakela, kodwa yonke ifuna ukhuseleko lomlilo olukhuselekileyo noluthembekileyo.
Imigangatho yokhuseleko lomlilo ihlala itshintsha njengoko kuvela ubuchwepheshe obutsha. Umzekelo, i-NFPA 20 ngoku isebenzisa iimpompo zesantya esiguquguqukayo kunye nezixhobo eziphezulu ezikumgangatho ophezulu endaweni yokuxhomekeka kuphela kwiivalvu zokunciphisa uxinzelelo. Imithetho yaseSingapore ngoku icela ii-PRV ezikrelekrele ezinokuqhagamshela kwiinkqubo zolawulo lwezakhiwo kwaye zisebenzise ukuxilongwa ngexesha langempela.
Indlela Uhlobo lweValve E yokunciphisa uxinzelelo oluhlangabezana ngayo neemfuno zokuthobela imithetho
Uhlobo lweValve E yokunciphisa uxinzelelo luhambelana neemfuno ezingqongqo zale migangatho. Ilawula uxinzelelo lwamanzi ukuze imibhobho kunye neepayipi zingadubuli okanye zivuze. Uyilo lwevalve luyivumela ukuba ilungise uxinzelelo lwe-outlet phakathi kweebha ezi-5 kunye nezi-8, oluhambelana neemfuno zezakhiwo ezininzi.

- Izinto zokuvala ezisemgangathweni zithintela ukuvuza kwaye zigcina uxinzelelo lwamanzi luqinile.
- Uyilo olukrelekrele aluvumeli ihamile yamanzi, enokuyonakalisa imibhobho.
Iivalvuumzimba olungeleleneyoivumela amanzi ukuba ahambe lula, kwaye ukulungiswa kwawo ngokuzenzekelayo kugcina uxinzelelo luzinzile. Abacimi-mlilo banokuthemba ukuba inkqubo iya kuhambisa amanzi xa bewafuna kakhulu. Izixhobo ezisemgangathweni ophezulu kunye nokuveliswa ngononophelo kwevalvu kuthetha ukuba iya kuhlala ixesha elide kwaye iqhubeke ikhusela abantu kunye nempahla.
Qaphela: Ulawulo oluthembekileyo loxinzelelo lukhusela izixhobo zokucima umlilo kwaye lunceda izixhobo zokutshiza zisebenze ngokukhawuleza, zimise umlilo ngaphambi kokuba usasazeke.
Uhlobo lweValve E yokunciphisa uxinzelelo lubalasele kuba luhlangabezana nemigangatho yokhuseleko yamazwe ngamazwe, lusebenzisa izixhobo ezihlala ixesha elide, kwaye lubonelela ngolawulo olulula ngesandla. Ezi mpawu ziyenza ibe yinxalenye ebalulekileyo yayo nayiphi na inkqubo ye-fire hydrant, nto leyo enceda izakhiwo ukuba zihlale zikhuselekile kwaye zithobela imithetho yokhuseleko lomlilo.
Ukuhlolwa kunye nokugcinwa kweValve E yokunciphisa uxinzelelo
Iinkqubo zoHlolo zokuthobela imithetho
Ukuhlolwa rhoqo kunceda ukugcina ivalvu yokunciphisa uxinzelelo isebenza ngokukhuselekileyo nangokuthembekileyo. Ngexesha lokuhlolwa, iingcali zijonga ukuvuza, imingxunya, kunye neempawu zokuguguleka kwinkqubo yovavanyo kunye nevalvu ephambili. Zikwajonga ukungcola okanye ukuvaleka kwiistrainers kunye neefiltha. Ukususa umoya kwinkqubo yovavanyo kuthintela ukufundwa okungekho ngqiqweni. Abahloli bavavanya ii-diaphragms ukuze babone ukuvuza kwaye baqinisekise ukuba zonke izibambo kunye nezixhobo zisendaweni yazo. La manyathelo anceda ekufumaneni iingxaki ezifana neevalvu ezaphukileyo, ii-orifices ezivaliweyo, okanye izihlalo ezigugileyo ngaphambi kokuba zibangele iingxaki ezinkulu.
Icebiso: Ukucoca izihluzo kunye nokujonga ukungcola kwiindawo zeevalvu kunokuthintela ukunyuka koxinzelelo kunye nokungaphumeleli kwenkqubo.
Uvavanyo kunye noQinisekiso lokuSebenza
Uvavanyo lubonisa ukuba ivalvu isebenza ngendlela efanele ukuba isebenze ngayo. Ngokwezikhokelo ze-NFPA, iimvavanyo ezimbini eziphambili zigcina ivalvu ikwimo ephezulu:
| Uhlobo lovavanyo | Izihlandlo | Inkcazo |
|---|---|---|
| Uvavanyo lokuGqibela oluPheleleyo | Rhoqo emva kweminyaka emi-5 | Ilinganisa uxinzelelo xa luhamba kakhulu; ijonga ukuba ivalvu iyalunciphisa na uxinzelelo ngokuchanekileyo. |
| Uvavanyo lokuhamba kwenxalenye | Ngonyaka | Ivula ivalvu kancinci ukuze iqhubeke ishukuma kwaye isebenza; iqinisekisa ukuba ayinamatheli. |
Ngexesha lezi vavanyo, iingcali zilinganisa uxinzelelo oluvela phezulu nasezantsi, amazinga okuhamba, kunye nendawo yevalvu. Bajonga indlela ivalvu elawula ngayo iincopho zoxinzelelo kwaye igcina uxinzelelo olujoliswe kulo luzinzile.
Iindlela ezilungileyo zoLondolozo
Ukugcinwa kakuhle kwevalvu kugcina ivalvu ithembekile kwaye yandisa ubomi bayo. Nazi ezinye zeendlela ezilungileyo:
- Lungiselela ukugcinwa kwevalvu ngokwemeko yayo, kungekuphela nje kwikhalenda.
