Ukuqonda indima yeAngle Hose Valves
Yintoni iAngle Hose Valve?
Ivalve yethumbu leengile licandelo elikhethekileyoiinkqubo zokukhusela umliloeyilelwe ukulawula ukuhamba kwamanzi. I-angle yayo ekhethekileyo ye-45-degree iququzelela ukudibanisa okulula kwimibhobho, ngakumbi kwiindawo ezivaliweyo. Ezi zivalo zidla ngokufumaneka ngeesayizi ezimbini: 1½” kunye no-2 ½”. Iisistim zemibhobho yodidi lwe-I kunye neye-III ziqhele ukusebenzisa iivalvu ezinkulu ezi-2 ½”, ngelixa iisistim zoDidi II zixhomekeke kubungakanani obuncinane be-1 ½”. Ufakelo lufuna imicu ye-taper yombhobho ehambelana nemigangatho ye-ANSI B2.1, iqinisekisa ukugcinwa okukhuselekileyo kunye nokungavuzi. Ukugcinwa rhoqo, kubandakanywa nokuhlolwa kokuvalwa okuqinileyo kunye nokutshintshwa kwecandelo kwimeko yokuvuza, kuqinisekisa ukusebenza kakuhle.
Kutheni le nto iivalvu ze-Angle Hose zibalulekile kuKhuseleko oluPhezulu loMlilo?
Izakhiwo eziphakamileyo zibonakalisa imingeni ekhethekileyo ngexesha longxamiseko lomlilo.Iivalvu ze-engile hosebadlale indima ebalulekileyo ekujonganeni nale mingeni ngokubonelela ngofikelelo lwamanzi oluthembekileyo kwiinzame zokucima umlilo. Zifakwe njengenxalenye yesixokelelwano sombhobho omileyo, ezi zivalo ziqinisekisa ukuba amanzi anokuhanjiswa ngokufanelekileyo kwimigangatho ephezulu. Uyilo lwabo olune-angled luphucula ukufikeleleka, ukuvumela abacimi bomlilo ukuba badibanise ngokukhawuleza i-hoses nakwiindawo ezinzima okanye ezinqabileyo. Ngokuhlangabezana noxinzelelo oluthile kunye neemfuno zokusebenza, iivalve ze-engile hose zinceda ukugcina ukuhamba kwamanzi okungaguqukiyo, okubalulekileyo ekuthinteleni imililo kwizakhiwo ezide.
Ukongezelela, ezi zivalo zinegalelo ekuthotyelweni kweekhowudi zokhuseleko lomlilo, eziyalela ukusetyenziswa kwazo kwizakhiwo eziphakamileyo. Izivalo ze-hose hose ezikhethwe ngokufanelekileyo kwaye zigcinwe azigcini nje ukwandisa ukusebenza kweenkqubo zokukhusela umlilo kodwa zikhusela ubomi kunye nepropathi ngexesha likaxakeka.
Iingqwalasela eziphambili zokuKhetha iValve ye-Angle Hose
Ukuhambelana ne-Standpipe Systems
Ukuqinisekisa ukuhambelana phakathi kweevalve ze-angle hose kunye neenkqubo ze-standpipe kubalulekile ekukhuseleni umlilo osebenzayo kwizakhiwo eziphakamileyo. Ezi zivalo kufuneka zihlangabezane neemfuno ezithile ukuze zisebenze ngaphandle komthungo ngaphakathi kwenkqubo. Ngokomzekelo, kufuneka babezidweliswe ngokweNFPA 14imigangatho kunye neempawu zangaphandle zeMigangatho yeHose yeSizwe (i-NHS) yokudibanisa i-hose ekhuselekileyo. Ii-Threaded caps zikhusela iintambo ze-hose kumonakalo, ngelixa ukulawulwa koxinzelelo kuqinisekisa ukuhanjiswa kwamanzi akhuselekileyo ngexesha likaxakeka.
| Imfuneko | Inkcazo |
|---|---|
| Iivalvu zeHose | Kufuneka zidweliswe ngokweNFPA 14 |
| Imisonto yeHose | Kufuneka ibe nemisonto yangaphandle yeMigangatho yeHose yeSizwe (NHS). |
| Iicaps ezinemisonto | Kuyafuneka ukukhusela imisonto yombhobho |
| Ulawulo loxinzelelo | Kufuneka unciphise uxinzelelo kumbhobho wodibaniso kumaxabiso akhankanyiweyo |
Uvavanyo olufanelekileyo lokuhambelana luqinisekisa ukuba i-valve ye-hose ye-angle idibanisa kakuhle kunye neenkqubo ze-standpipe, zokwandisa ukuthembeka kwazo ngexesha likaxakeka lomlilo.
UKhetho lweMathiriyeli yoKuhlala ixesha elide
Ukuqina kwezinto eziphathekayo kudlala indima ebalulekileyo ekusebenzeni kweevalve ze-hose hose, ngakumbi kwizicelo eziphakamileyo. Izinto ezikumgangatho ophezulu ezifana nobhedu kunye nobhedu zisetyenziswa ngokuqhelekileyo ngenxa yokumelana nokubola kunye nokukwazi ukumelana neemeko ezinzima. Imigangatho efana ne-MSS SP-80 kunye ne-MSS SP-85 ichaza imathiriyeli kunye neemfuno zobukhulu bobhedu kunye neevalvu zentsimbi ezingwevu, iqinisekisa ukuthembeka kwazo.
- I-ASME B16.34ichaza iiklasi zoxinzelelo kwiivalvu, ichaza uxinzelelo oluphezulu oluvumelekileyo lokusebenza kumaqondo obushushu ahlukeneyo.
- I-MSS SP-80ilawula iivalvu zobhedu, ezinokubamba ukuya kuthi ga kwi-300 PSI kumaqondo obushushu aqhelekileyo kunye ne-150 PSI kwi-406°F.
- I-MSS SP-85iqinisekisa ukuba iivalvu zentsimbi ezingwevu ziyahlangabezana nebenchmarks zokuqina.
Ngokomzekelo, iivalve ze-bronze ze-Class 150 ezilinganiswe phantsi kwe-MSS SP-80 zinokusebenza kwi-200 PSI phakathi kwe-20 ° F kunye ne-150 ° F, izenza zilungele iimeko ezibango. Ukukhetha izinto ezizinzileyo ziqinisekisa ubomi benkonzo ende kunye nokusebenza okuhambelanayo phantsi koxinzelelo.
Imilinganiselo yoxinzelelo kunye neeMfuno zokuSebenza
Ukulinganiswa koxinzelelo kugqiba imida yokusebenza kweevalve ze-hose hose, ukuqinisekisa ukuba zenza ngokuthembekileyo ngexesha likaxakeka. Iivalve kufuneka zihlangabezane neemfuneko ezithile zoxinzelelo kunye nobushushu ukujongana neemfuno zeenkqubo zokukhusela umlilo eziphakamileyo.
| Inkcazo | Iinkcukacha |
|---|---|
| Umzekelo | Bristol BF59/A99 |
| Ukuvunywa kunye neSiqinisekiso | Uluhlu lwe-UL, oluhambelana nemigangatho ye-ANSI / UL 1468 |
| Izinto eziphathekayo | Ubhedu oluphezulu olunobhedu olucacileyo lokumelana nokubola |
| Ixabiso loxinzelelo | Uxinzelelo lokusebenza lwe-175 PSI (i-12 bar), uxinzelelo lovavanyo lwe-24 bar |
| Uluhlu lobushushu | Isebenza ngokufanelekileyo phakathi kwe-0ºC ukuya kuma-38ºC |
| Ukuqina | Yenzelwe ubomi obude benkonzo kwiindawo ezifuna ngamandla |
| Isicelo | Isetyenziselwa ukukhusela umlilo, i-standpipe, kunye neenkqubo zokufafaza |
Iivalve ezifana neBristol BF59 / A99 zibonisa ukusebenza okungaqhelekanga, kunye noxinzelelo olusebenzayo lwe-175 PSI kunye noxinzelelo lovavanyo lwe-bar ye-24. Ukwakhiwa kwabo okuqinileyo kuqinisekisa ukuthembeka kwiimeko eziphezulu zoxinzelelo, okwenza ukuba zilungele iinkqubo zokukhusela umlilo kwizakhiwo ezide.
Ukuthotyelwa kweeKhowudi zoKhuseleko loMlilo kunye neMigangatho
Ukuqinisekisa ukuthotyelwa kweekhowudi zokhuseleko lomlilo kunye nemigangatho kubalulekile xa ukhetha i-valve ye-hose ye-angle kwizakhiwo eziphakamileyo. Le migaqo imisela iimfuno ezisezantsi zokusebenza, ukufakwa kunye nokugcinwa, ukuqinisekisa ukuba iinkqubo zokukhusela umlilo zisebenza ngokufanelekileyo ngexesha likaxakeka. Ukuthobela le migangatho akuphuculi nje kuphela ukhuseleko kodwa kukwaqinisekisa ukuthotyelwa komthetho kubanini-zakhiwo nabaphathi.
Iikhowudi zokhuseleko lomlilo, ezifana nezo zichazwe nguMbutho woKhuseleko loMlilo weSizwe (i-NFPA), zibonelela ngezikhokelo ezicacileyo kwii-valve ze-hose hose kunye namacandelo ahambelanayo. Umzekelo, iNFPA 14 ikhankanya uyilo, ufakelo, kunye novavanyo lwemibhobho emileyo kunye nenkqubo yombhobho. Le migangatho iqinisekisa ukuba i-valve ihlangabezana nemilinganiselo yokusebenza ebalulekileyo, njengokulinganisa uxinzelelo kunye neemfuno zokuhamba kwamanzi.
Le theyibhile ilandelayo igxininisa iimfuno eziphambili zevalvu yethumbu kunye neenkqubo zombhobho omileyo:
| Imfuneko | Inkcazo |
|---|---|
| Umbhobho wokukhupha | Yonke i-1.5 ″ okanye i-hose hose encinci kufuneka ixhotyiswe kwaye ilungele ukusetyenziswa. |
| Uhlobo lweHose | Iinkqubo zeStandpipe ezifakwe emva koJanuwari 1, 1981, kufuneka zisebenzise ithumbu elinemigca. |
| Uxinzelelo | Uxinzelelo oluguquguqukayo kumlomo kufuneka lube phakathi kwe-30 psi (210 kPa) kunye ne-125 psi (860 kPa). |
| Ubonelelo ngamanzi | Ubuncinane bonikezelo lwamanzi kufuneka lube ziilitha ezili-100 ngomzuzu (6.3 l/s) ubuncinane imizuzu engama-30. |
| Uvavanyo lweHydrostatic | Imibhobho kufuneka ivavanywe ungekho ngaphantsi kwe-200 psi (1380 kPa) ubuncinane iiyure ezi-2. |
| Uvavanyo lweHose | Umbhobho kufuneka uvavanywe ungekho ngaphantsi kwe-200 psi (1380 kPa) phambi kokuba ufakwe enkonzweni. |
| Isondlo | Iinkqubo zemibhobho kufuneka zihlolwe ubuncinane ngonyaka nasemva kokusetyenziswa ngalunye. |
Ezi mfuno ziqinisekisa ukuba i-valve ye-hose ye-angle kunye neenkqubo ezinxulumene nazo zisebenza ngokuthembekileyo phantsi kweemeko zoxinzelelo oluphezulu. Ngokomzekelo, uvavanyo lwe-hydrostatic kwi-200 psi luqinisekisa ukunyaniseka kombhobho, ngelixa ukuhlolwa konyaka kunceda ukuchonga imiba enokubakho ngaphambi kokuba inyuke.
Ukuthobela kukwabandakanya ukukhetha iivalvu ezihlangabezana neziqinisekiso ezithile. Iivalve ezininzi ezikumgangatho ophezulu, ezifana nezo zenziwe yiYuyao World Fire Fighting Equipment Factory, zifakwe kuluhlu lwe-UL kwaye zihambelana nemigangatho ye-ANSI / UL 1468.
