Yog hose nozzles universal

Hose nozzles yog dav siv hauv kev tua hluav taws, thiab ntau tus neeg muaj lus nug:Yogcev nozzlesuniversal?

Xyoo 1964 National Fire Protection Association (NFPA) tau tsim cov txheej txheem qhia txog kev ua tau zoo rau cov nozzles siv hauv kev tua hluav taws. Cov qauv no tau hloov kho xyoo 2018. Cov qauv kho dua tshiab faib cov hose nozzles ua plaub pawg: qhov yooj yim, tsis tu ncua nkas loos, qhov siab tsis tu ncua, thiab tsis tu ncua / xaiv gallonage.

Basic
Basic nozzles yog hluav taws hose nozzles nrog ib tug adjustable-hom tshuaj tsuag. Qhov ntsuas qhov tso tawm yog xa tawm ntawm qhov kev xaiv nozzle siab thiab teeb tsa. Lub nkas loos ib feeb (GPM) thiab PSI ntawm lub nozzle txawv raws li cov kwj hloov ntawm ncaj nraim mus rau pos huab.

Tsis tu ncua Gallonage
Tsis tu ncua gallonage nozzles kuj yog adjustable-hom tshuaj tsuag nozzles. Txawm li cas los xij, lawv tso tawm ntawm tus nqi tas li los ntawm ntau yam ntawm cov qauv, ncaj nraim mus rau qhov dav, ntawm qhov raug xaiv. Raws li tus qauv nozzle hloov, qhov loj ntawm lub qhov ncauj tseem zoo ib yam kom tswj tau qhov GPM tsis tu ncua.

Siab tsis tu ncua
Kuj hu ua tsis siv neeg, qhov siab tsis tu ncua nozzles yog tus kheej piav qhia. Lub siab ntawm cov nozzles tseem nyob tas li los ntawm ntau qhov kev tso tawm. Cov qauv tshuaj tsuag yog kho tau, thiab tus neeg teb xov tooj tuaj yeem xaiv los ntawm ib qho ntawm ntau qhov sib txawv ntawm qhov sib txawv. Qhov nozzle style pab tau lees tias kwj ncav cuag nrog tus kheej-kho tivthaiv kom lub siab ruaj khov.

Tsis tu ncua / Xaiv Gallonage
Constant/select gallonage nozzles muaj qhov tso tawm tas li uas tso cai rau kev hloov kho ntawm phau ntawv kom cuam tshuam tus nqi tso tawm ua ntej thaum lub nozzle ntws.

Lwm qhov yuav tsum tau xav txog thaum xaiv qhov hluav taws kub hose nozzle yog cov xov. Cov xov yog dab tsi txuas lub nozzle rau lub hose. Tag nrho cov nozzles muaj threads, tab sis tsis yog tag nrho cov threads yog tib yam. Yog li ntawd, cov neeg siv yuav tsum xav txog qhov sib xws ntawm nozzles thiab hoses. Cov xov tseem ceeb rau cov hluav taws kub hose nozzles yog National Standard Thread (NST), National Pipe Straight Hose (NPSH), thiab National Pipe Thread (NPT).

NST threads, tseem hu ua National Hose (NH) threads, yog cov khoom siv hluav taws xob tshaj plaws hauv Teb Chaws Asmeskas NPSH threads muaj tib cov xov ib nti li NPT, tab sis cov xov tsis taper. NST thiab NPSH yog ob qho tib si cov xov ncaj, tab sis lawv tsis sib xws. Muaj hoses thiab nozzles nrog sib txawv, incompatible threads tsim ib qho xwm txheej txaus ntshai, ua rau lub neej thiab khoom muaj kev pheej hmoo.

NH

National Hose thread (NH), tseem hu ua National Standard Thread (NST). Nws yog hom hluav taws kub hose txuas feem ntau siv hauv Tebchaws Meskas. Cov txiv neej thiab poj niam ncaj (tsis-tapered) threads ntsia hlau ua ke thiab kev sib txuas yog kaw nrog lub gasket.

British instantaneous coupling

Kuj hu ua John Morris Coupling, BS336 Instantaneous hluav taws couplings zoo ib yam li tsim rau cov camlock fittings, thiab yog siv los ntawm; UK, Irish, New Zealand, Indian & Hong Kong tua hluav taws.

Tshuab

Japanese ceev txuas thiab disconnect coupling siv rau hluav taws hoses nyob rau hauv Nyiv thiab txhais los ntawm JIS B9911

Gost

Kev sib deev tsis muaj kev sib deev, aka Bogdan coupler,^[21]siv rau hauv hluav taws hoses nyob rau hauv Russia thiab txhais los ntawm GOST R 53279-2009, muaj nyob rau hauv ntau qhov ntau thiab tsawg, xws li DN 25, DN 40, DN 50, DN 65, DN 70, DN 80, DN 100, DN 125, thiab DN 150 .

Storz

Lub Storz coupling yog lub quarter-tig los yog kev sib deev tsis sib deev, feem ntau siv los txuas rau hluav taws kub hydrants. Nws yog ib qho yooj yim mus cuag, tsis muaj ib tug txiv neej los yog poj niam kawg, thiab lugs nyob rau hauv lub sib koom tes. Qhov no yog tus qauv txuas ntawm cov hluav taws kub hoses hauv Denmark, Lub Tebchaws Yelemees, Austria, Poland, Switzerland, Sweden, Netherlands thiab Greece.^[26]Nws kuj tau siv dav hauv Australia. Nws tuaj yeem raug tsim los ntawm kev ua haujlwm rau kev sib txuas ntawm cov hose dav dav thiab cov ntawv thov tsis tshua muaj siab, tab sis rau kev tua hluav taws, nws yog qhov zoo dua los siv forgings los lav qhov kev nyab xeeb thiab kav ntev ntawm kev sib txuas.

Hluav taws kub hose nozzles yog ib qho cuab yeej tseem ceeb rau kev sib ntaus sib tua hluav taws hauv txhua qhov xwm txheej kub ntxhov. Lawv tau tsim los muab cov dej ntws tswj uas pab tua hluav taws thiab tiv thaiv lub neej thiab khoom. Ib lo lus nug uas tib neeg nug yog yog tias qhov hluav taws kub hose nozzles yog universal. Cov lus teb yog tias feem ntau qhov hluav taws kub hose nozzles yog tus qauv thiab tso cai rau kev sib raug zoo ntawm cov hoses tsis hais lawv hom lossis cov chaw tsim khoom. Qhov no txhais tau hais tias cov neeg tua hluav taws tuaj yeem siv cov hoses sib txawv thiab cov nozzles ua ke yam tsis muaj teeb meem. Standardization tau ua tiav los ntawm kev ua raws li cov qauv kev lag luam thiab cov txheej txheem, uas tau tsim los ntawm lub sijhawm. Cov qauv no xyuas kom meej tias cov hluav taws kub hose nozzles txhim khu kev qha, ruaj khov, thiab ua haujlwm zoo. Lawv kuj pab txhim kho kev nyab xeeb los ntawm kev txo qis kev pheej hmoo ntawm cov khoom siv tsis ua haujlwm thiab ua kom muaj txiaj ntsig zoo ntawm kev tua hluav taws. Txawm hais tias tej zaum yuav muaj qee qhov kev hloov pauv hauv kev tsim thiab kev ua haujlwm ntawm qhov sib txawv ntawm qhov hluav taws kub hose nozzles, lawv feem ntau hloov tau thiab muab tib theem siab ntawm kev ua haujlwm. Feem ntau cov kev cob qhia kws tua hluav taws suav nrog kev siv cov hose nozzles kom raug thiab muab cov lus qhia txog yuav ua li cas xaiv lub nozzle rau qhov xwm txheej.
