Ukuqonda Indima Yeevalvu Ze-Angle Hose
Yintoni iValve yeHose ye-Angle?
Ivalvu yepayipi ye-angle yinxalenye ekhethekileyo yeiinkqubo zokukhusela umliloYenzelwe ukulawula ukuhamba kwamanzi. I-engile yayo ekhethekileyo engama-45-degree yenza kube lula ukunxibelelana neepayipi, ingakumbi kwiindawo ezivalekileyo. Ezi valve zihlala zifumaneka ngobukhulu obubini: 1 ½” kunye 2 ½”. Iinkqubo zemibhobho ezime ndawonye zeClass I kunye neIII zihlala zisebenzisa iivalvu ezinkulu ze-2 ½”, ngelixa iinkqubo zeClass II zixhomekeke kubukhulu obuncinci be-1 ½”. Ukufakelwa kufuna imisonto yemibhobho ethambileyo ehambelana nemigangatho ye-ANSI B2.1, ukuqinisekisa ukulingana okukhuselekileyo nokungavuzi. Ukugcinwa rhoqo, kubandakanya ukuhlolwa kokuvalwa okuqinileyo kunye nokutshintshwa kwecandelo xa kukho ukuvuza, kuqinisekisa ukusebenza kakuhle.
Kutheni ii-Angle Hose Valve Zibalulekile Kukhuseleko Lomlilo Oluphezulu?
Izakhiwo eziphakamileyo zineengxaki ezikhethekileyo ngexesha leengxamiseko zomlilo.Iivalvu zepayipi ye-engilezidlala indima ebalulekileyo ekusombululeni le mingeni ngokubonelela ngokufikelela kwamanzi okuthembekileyo kwimizamo yokulwa nomlilo. Zifakwe njengenxalenye yenkqubo yemibhobho emileyo, ezi valve ziqinisekisa ukuba amanzi anokuhanjiswa ngokufanelekileyo kumgangatho ophezulu. Uyilo lwazo olugobileyo luphucula ukufikeleleka, okuvumela abacimi-mlilo ukuba baqhagamshele ngokukhawuleza iipayipi nokuba zikwiindawo ezixineneyo okanye ezingaqhelekanga. Ngokuhlangabezana neemfuno ezithile zoxinzelelo kunye nokusebenza, iivalvu zepayipi engile zinceda ukugcina ukuhamba kwamanzi rhoqo, okubaluleke kakhulu ekuthinteleni imililo kwizakhiwo ezinde.
Ukongeza, ezi valve zinegalelo ekuthobeleni imithetho yokhuseleko lomlilo, eyalela ukuba zisetyenziswe kwizakhiwo eziphakamileyo. Iivalvu zepayipi ye-engile ezikhethwe kakuhle nezigcinwe kakuhle aziphuculi nje kuphela ukusebenza kakuhle kweenkqubo zokukhusela umlilo kodwa zikhusela nobomi kunye nempahla ngexesha leengxakeko.
Izinto Ezibalulekileyo Omele Uziqwalasele Xa Ukhetha Ivalvu Yepayipi Ye-Angle
Ukuhambelana neeNkqubo zeMibhobho eziSimayo
Ukuqinisekisa ukuba iivalvu ze-engile kunye neenkqubo zemibhobho ezimiyo zihambelana kakuhle kubalulekile ukuze kukhuseleke umlilo kwizakhiwo eziphakamileyo. Ezi valve kufuneka zihlangabezane neemfuno ezithile ukuze zisebenze kakuhle ngaphakathi kwenkqubo. Umzekelo, kufuneka zibezidweliswe ngokwe-NFPA 14imigangatho kwaye inemisonto yangaphandle yeNational Hose Standard (NHS) yokudibanisa imibhobho ekhuselekileyo. Izigqubuthelo ezinemisonto zikhusela imisonto yemibhobho ekonakalisweni, ngelixa ulawulo loxinzelelo luqinisekisa ukuhanjiswa kwamanzi okukhuselekileyo ngexesha leengxakeko.
| Imfuneko | Inkcazo |
|---|---|
| Iivalvu zombhobho | Kufuneka kudweliswe ngokwe-NFPA 14 |
| Imisonto yepayipi | Kufuneka ube nemisonto yangaphandle yeNational Hose Standard (NHS) |

Ukuthobela iiKhowudi kunye neMigangatho yoKhuseleko loMlilo
Ukuqinisekisa ukuthotyelwa kwemithetho kunye nemigangatho yokhuseleko lomlilo kubalulekile xa ukhetha ivalvu yepayipi ye-engile yezakhiwo eziphakamileyo. Le mithetho imisela iimfuno ezisezantsi zokusebenza, ukufakelwa, kunye nokugcinwa, ukuqinisekisa ukuba iinkqubo zokukhusela umlilo zisebenza ngokufanelekileyo ngexesha likaxakeka. Ukunamathela kule migangatho akupheleli nje ekuphuculeni ukhuseleko kodwa kuqinisekisa ukuthotyelwa komthetho kubanini bezakhiwo kunye nabaphathi.
Iikhowudi zokhuseleko lomlilo, ezifana nezo zichazwe yiNational Fire Protection Association (NFPA), zibonelela ngezikhokelo ezineenkcukacha zeevalvu ze-engile kunye nezinto ezinxulumene nazo. Umzekelo, i-NFPA 14 ichaza uyilo, ukufakelwa, kunye novavanyo lweenkqubo zemibhobho emileyo kunye nepayipi. Le migangatho iqinisekisa ukuba iivalvu ziyahlangabezana nemigangatho yokusebenza ebalulekileyo, efana novavanyo loxinzelelo kunye neemfuno zokuhamba kwamanzi.
Le theyibhile ilandelayo igxininisa iimfuno eziphambili zeevalvu zepayipi kunye neenkqubo zemibhobho emileyo:
| Imfuneko | Inkcazo |
|---|---|
| Indawo yokuphuma yamanzi | Yonke ipayipi yokukhupha amanzi eyi-1.5″ okanye encinci kufuneka ixhotyiswe kwaye ilungele ukusetyenziswa. |
| Uhlobo lwepayipi | Iinkqubo zeembhobho ezimiyo ezifakwe emva komhla woku-1 kweyoMqungu, 1981, kufuneka zisebenzise ipayipi eneentambo. |
| Uxinzelelo | Uxinzelelo olutshintshayo kwi-nozzle kufuneka lube phakathi kwe-30 psi (210 kPa) kunye ne-125 psi (860 kPa). |
| Ubonelelo ngamanzi | Ubuncinane bobonelelo lwamanzi kufuneka lube ziilitha ezili-100 ngomzuzu (6.3 l/s) ubuncinane imizuzu engama-30. |
| Uvavanyo lwe-Hydrostatic | Imibhobho mayivavanywe ubuncinane kwii-200 psi (1380 kPa) ubuncinane iiyure ezi-2. |
| Uvavanyo lweMibhobho | Umbhobho kufuneka uvavanywe ubuncinane kwi-200 psi (1380 kPa) ngaphambi kokuba usetyenziswe. |
| Ulondolozo | Iinkqubo zepayipi kufuneka zihlolwe ubuncinane ngonyaka nasemva kokusetyenziswa ngakunye. |
Ezi mfuneko ziqinisekisa ukuba ivalvu yepayipi ye-engile kunye neenkqubo ezinxulumene nayo zisebenza ngokuthembekileyo phantsi kweemeko zoxinzelelo oluphezulu.
