Ivalve yokunciphisa uxinzelelo lwevalve E Uhlobo lugcina iinkqubo zombhobho womlilo zikhuselekile ngokulawula uxinzelelo lwamanzi. Banceda ukuthintela uxinzelelo olugqithisileyo, ngoko ke inkqubo isebenza xa kufuneka.IValve yokunciphisa uxinzelelo lwamanzi, IValve yokuNcitshiswa koxinzelelo lweMoto, kwayeI-Valve yokuNcitshiswa koxinzelelo lomatshinizonke zixhasa ukuthotyelwa kwemigangatho yokhuseleko lomlilo ngokujongwa rhoqo kunye nokugcinwa.

Uxinzelelo lokuNcitshiswa kweValve E Uhlobo: Imisebenzi yokuThobela

Injongo kunye noMsebenzi

IIvalve yokunciphisa uxinzelelo lwe-E Uhloboidlala indima enkulu kwiinkqubo zokukhusela umlilo. Igcina uxinzelelo lwamanzi kwinqanaba elikhuselekileyo, ngoko ke imibhobho kunye nemibhobho ayiqhumi ngexesha likaxakeka. Le valve isebenza ngokulungelelanisa ukuhamba ukusuka kumthombo oyintloko wamanzi. Xa uxinzelelo lokungena lutshintsha, i-valve ivula ngokuzenzekelayo okanye ivale ukugcina uxinzelelo lwe-outlet luzinzile. Abacimi bomlilo banokuthembela kumlambo othembekileyo wamanzi, nokuba uxinzelelo kwinkqubo yenyuka okanye yehla. Umzimba wobhedu oqinileyo wevalve unokumelana noxinzelelo oluphezulu, ukuya kuthi ga kwi-30 bar, kwaye ingena lula kwiindidi ezininzi zeenkqubo zombhobho womlilo. Abantu bahlala bebona ezi zivalo kwiindawo ezifana nezibhedlele, iivenkile ezinkulu, kunye nezakhiwo ezide. Banceda ukukhusela izixhobo emonakalweni kwaye baqinisekise ukuba amanzi ahlala elungile xa kufuneka.

Iimpawu eziphambili ezixhasa iMigangatho yoKhuseleko loMlilo

I-valve yokunciphisa uxinzelelo lwe-E Type iza neempawu ezinceda ukuhlangabezana nemithetho engqongqo yokhuseleko lomlilo. Yiiqinisekisiwe kwi-BS 5041 iCandelo 1 kunye ne-ISO 9001: 2015, ibonisa ukuba iyahambelana nemigangatho yokhuseleko yehlabathi. I-valve inokulungelelanisa uxinzelelo lwe-outlet phakathi kwe-5 kunye ne-8 imivalo, ebalulekileyo kwiimfuno ezahlukeneyo zokwakha. Uyilo lwayo luvumela ukufakwa ngokukhawuleza kunye nokugcinwa lula. I-valve iphinda ixhase izinga lokuhamba okuphezulu, ukuya kwi-1400 ilitha ngomzuzu, okunceda abacimi bomlilo balawule umlilo ngokukhawuleza. Kwizakhiwo eziphakamileyo, le valve ivumela iinjineli ukuba zibeke uxinzelelo olufanelekileyo kumgangatho ngamnye, ziqinisekisa ukuba umbhobho ngamnye ufumana amanzi awoneleyo. Ezi mpawu zinceda ukuthintela ukusilela kwenkqubo kunye nokugcina abantu kunye nepropathi zikhuselekile ngexesha lomlilo.

Uxinzelelo lokunciphisa iValve kunye neMigangatho yoKhuseleko loMlilo

Iikhowudi kunye neMigangatho efanelekileyo (NFPA, IBC, BS 5041)

Iikhowudi zokhuseleko lomlilo zibeka imigaqo yendlela izakhiwo ezikhusela ngayo abantu kunye nepropathi emlilweni. Uxinzelelo lwe-Valve E Uhlobo lunceda ukuhlangabezana nale mithetho ngokulawula uxinzelelo lwamanzi kwiinkqubo zokucima umlilo. Amazwe ahlukeneyo kunye nemimandla basebenzisa imigangatho yabo, kodwa abaninzi balandela izikhokelo ezivela kumaqela afana ne-NFPA, IBC, kunye ne-BS 5041.

Nantsi ukujonga ngokukhawuleza ukuba le migangatho ithelekiseka njani:

Ingcebiso: Imigangatho yamazwe ngamazwe inokumisela imida yoxinzelelo eyahlukeneyo kunye nemithetho yokufakela, kodwa zonke zifuna ukhuseleko, ukhuseleko lomlilo oluthembekileyo.

Imigangatho yokhuseleko lomlilo iyaqhubeka itshintsha njengoko kubonakala ubugcisa obutsha. Ngokomzekelo, i-NFPA 20 ngoku isebenzisa iimpompo zesantya eziguquguqukayo kunye neengxenye eziphezulu zoxinzelelo endaweni yokuxhomekeka kuphela kwiivalve zokunciphisa uxinzelelo. Imithetho yaseSingapore ngoku icela ii-PRV ezihlakaniphile ezinokuxhuma kwiinkqubo zokulawula izakhiwo kunye nokusebenzisa ukuxilongwa kwexesha langempela.

Njani Uxinzelelo lokuNcitshiswa kweValve E Uhlobo ludibana neeMfuno zokuThobela

Uhlobo lweValve E yokuNcitshiswa koxinzelelo luhambelana neemfuno ezingqongqo zale migangatho. Ilawula uxinzelelo lwamanzi ukuze imibhobho kunye nemibhobho ingagqabhuki okanye ivuze. Uyilo lwevalve luyivumela ukuba ilungelelanise uxinzelelo lokuphuma phakathi kwe-5 kunye ne-8 imivalo, ehambelana neemfuno zezakhiwo ezininzi. Umzimba wayo owomeleleyo wobhedu kunye nokuphosa okukumgangatho ophezulu kuyinceda ukuba iphumelele ukuhamba kwamanzi okunzima kunye novavanyo loxinzelelo, njengoko i-BS 5041 ifuna.

• Ivalve igcina uxinzelelo lwamanzi luzinzile, nangona unikezelo lutshintsha.
• Ixhasa amazinga aphezulu okuhamba, ngoko ke abacimi bomlilo bafumana amanzi aneleyo ngokukhawuleza.
• Ulawulo lwe-valve ye-manual kunye ne-cap yokukhusela yenza kube lula ukuyisebenzisa kunye nokugcina.
• Ixhathisa ukubola, oku kuthetha ukuba isebenza kakuhle iminyaka.

Uhlobo lweValve E yokuNcitshiswa koxinzelelo lukwangena kwiinkqubo ezilandela i-NFPA 13 kunye ne-NFPA 14. Ezi khowudi zibeka uxinzelelo oluphezulu lokuxhunyelelwa kwe-hose kwaye zifuna izixhobo zokulawula uxinzelelo xa loo mida idlulisiwe. Ukukwazi kwevalve ukujongana noxinzelelo oluphezulu lokungena kunye nokunciphisa ngokukhuselekileyo kunceda ukuba izakhiwo zihlale ngaphakathi kwale mida.

Ukuthintela Ukungaphumeleli kweNkqubo kunye nokuqinisekisa ukusebenza okuthembekileyo

Iinkqubo zombhobho womlilo kufuneka zisebenze ngalo lonke ixesha kukho unxunguphalo. Uhlobo lwe-E lokunciphisa uxinzelelo lweValve lunceda ukukhusela iingxaki eziqhelekileyo ezinokumisa inkqubo ekusebenzeni.

• Ukugcinwa rhoqoigcina ivalve isebenza kakuhle.
• Umzimba wobhedu umelana nomhlwa kunye nokubola, ngoko ke ivalve ayibambeki.
• Izitywini ezilungileyo zimisa ukuvuza kwaye zigcine uxinzelelo lwamanzi lomelele.
• Uyilo oluhlakaniphile luthintela isando samanzi, esinokuyonakalisa imibhobho.

Ivalve yeumzimba ophuculweyoivumela amanzi ukuba ahambe ngokulula, kwaye ukulungelelaniswa kwawo ngokuzenzekelayo kugcina uxinzelelo oluzinzileyo. Abacimi-mlilo banokuthemba ukuba inkqubo iya kuhambisa amanzi xa bewafuna kakhulu. Izinto ezikumgangatho ophezulu wevalve kunye nokuveliswa ngononophelo kuthetha ukuba iya kuhlala ixesha elide kwaye igcine ukukhusela abantu kunye nepropathi.

Qaphela: Ummiselo othembekileyo woxinzelelo ukhusela izixhobo zokucima umlilo kwaye unceda izitshizi zisebenze ngokukhawuleza, zinqande umlilo ngaphambi kokuba usasazeke.

I-Pressure Reducing Valve E Type ivelele ngenxa yokuba ihlangabezana nemigangatho yokhuseleko lwamazwe ngamazwe, isebenzisa izinto ezihlala ixesha elide, kwaye inika ulawulo olulula lwezandla. Ezi mpawu zenza kube yinxalenye ephambili kuyo nayiphi na inkqubo yokucima umlilo, ukunceda izakhiwo zihlale zikhuselekile kwaye zihambelana neekhowudi zokhuseleko lomlilo.

Ukuhlolwa kunye nokuLondolozwa koxinzelelo lweValve E ye-E

Iinkqubo zokuHlola ukuThobela

Ukuhlolwa rhoqo kunceda ukugcina ivalve yokunciphisa uxinzelelo isebenza ngokukhuselekileyo nangokuthembekileyo. Ngexesha lokuhlolwa, amagcisa ajonga ukuvuza, iintanda, kunye neempawu zokuguga kwinkqubo yokulinga kunye nevalve ephambili. Bakwajonga ukungcola okanye ukuvaleka kwizihluzi kunye nezihluzi. Ukususa umoya kwinkqubo yokulinga kuthintela ukufunda okungeyonyani. Abahloli bavavanya i-diaphragm malunga nokuvuza kwaye baqinisekise ukuba zonke izibambo kunye nezixhobo zisendaweni. La manyathelo anceda ukubona iingxaki ezifana neevalvu ezaphukileyo, ii-orifices ezivaliweyo, okanye izihlalo ezigugileyo ngaphambi kokuba zibangele imiba emikhulu.

Icebiso: Ukucoca izihluzi kunye nokujonga ukungcola kwiindawo zevalve kunokuthintela i-spikes yoxinzelelo kunye nokusilela kwenkqubo.

Uvavanyo kunye noQinisekiso lokuSebenza

Uvavanyo lubonisa ukuba ivalve isebenza njengoko kufanele. Ngokwezikhokelo zeNFPA, iimvavanyo ezimbini eziphambili zigcina ivalve ikwimo ephezulu:

Ngethuba lolu vavanyo, amagcisa alinganisa uxinzelelo oluphezulu kunye nolusezantsi, amazinga okuhamba, kunye nendawo yevalvu. Bajonga indlela ivalve elawula kakuhle ngayo iincopho zoxinzelelo kwaye igcina uxinzelelo olujoliswe kuyo luzinzile.

ULondolozo lweyona Nkqubo iLungileyo

Ukugcinwa kakuhle kugcina ivalve ithembekile kwaye yandisa ubomi bayo. Nazi ezinye iindlela zokusebenza ezilungileyo:

1. Ukugcinwa kweshedyuli ngokusekelwe kwimeko yevalve, kungekhona nje ikhalenda.
2. Thambisa iindawo ezihambayo ukuze uyeke ukuncamathela.
3. Sebenzisa izinzwa ukujonga ukusebenza kwevalvu ngexesha lokwenyani.
4. Gcina iivalvu ezisecaleni kwindawo ezicocekileyo, ezomileyo.
5. Ukuvala ivalvu yokuvuleka ukuze kungene ubumdaka.
6. Jikelezisa isitokhwe ukugcina amatywina kunye nezinto zokuthambisa zintsha.
7. Landela imigangatho yoshishino ngenyathelo ngalinye.

Le mikhwa inceda i-valve yokunciphisa uxinzelelo ihlale ihambelana kwaye ilungele iimeko zikaxakeka.

Ukuhlolwa nokugcinwa rhoqo rhoqo kugcina izixhobo zombhobho womlilo zikhuselekile kwaye zithembekile.

1. Ngekota ujonga iingxaki zokubamba kwangoko.
2. Uvavanyo lonyaka kunye neminyaka emihlanu luqinisekisa ukuba iivalvu ziyasebenza xa kufuneka.
   Ukungawahoyi la manyathelo kunokukhokelela ekungaphumeleli kwenkqubo, ingxaki yezomthetho, kunye neendleko eziphezulu ze-inshurensi. Hlala ukhuthele ukukhusela abantu kunye nepropathi.
