Yuav ua li cas xaiv lub valve rau aerosol?(kev tshawb fawb)
Raws li British Aerosol Manufacturers Association (BAMA), niaj hnub no muaj ntau tshaj 200 aerosol khoom siv nyob rau hauv tus kheej, lub tsev, industrial, ua liaj ua teb, kev tsim kho, hluav taws kub, kev nyab xeeb, kev kho mob thiab lwm yam kev lag luam.
Aerosol valve zoo li tsis tseem ceeb, tab sis txheeb ze rau tag nrho cov khoom aerosol yog qhov tseem ceeb tshaj plaws, tsis tsuas yog cuam tshuam nrog kev sib khi ntawm cov khoom, tab sis kuj muaj feem xyuam rau cov nyhuv ejection, ntawm chav kawm, kuj muaj feem xyuam rau kev ruaj ntseg ntawm tag nrho cov khoom aerosol.Yog li ntawd, yuav ua li cas xaiv lub valve tsim nyog yuav tsum tau saib xyuas hauv kev tsim cov khoom aerosol.
cuaj caum feem pua ntawm cov li qub siv nyob rau hauv North America yog tsim los ntawm Percision, Seaquist thiab Summit, nrog rau seem tsim los ntawm Newman-Green, Bespak, Beardg, Emson, Riker thiab Coster.Seaquist morphed rau hauv Aptar Group, uas tau txais Emson hauv 1999. Cov neeg muag khoom paub zoo hauv kev ua lag luam kuj suav nrog Lindal, Mitani, thiab lwm yam. Thiab cov valve hauv tsev feem ntau yog los ntawm Tebchaws Meskas, precision, cimB thiab lwm yam manufacturers.
Yog hais tias los ntawm pawg valve, aerosol feem ntau muab faib ua ob pawg: ib thiab ob.Ib tug yuan aerosol lub ntsiab qauv muaj xws li: tank, valve, txheej cover, laub khawm, projectile neeg sawv cev, khoom lub cev.Cov txiaj ntsig tseem ceeb ntawm binary aerosol muaj xws li: tank, valve, multilayer aluminium hnab, txheej npog, laub khawm, khoom siv lub cev, compressed roj.
Valve feem ntau muaj xws li: sealing khob, sab nrauv gasket, sab hauv gasket, qia, caij nplooj ntoos hlav, valve chamber, straw thiab lwm yam xya qhov chaw, suav nrog cov khoom sib txawv, qhov loj thiab cov qauv thiab lwm yam, txoj kev xav ntawm lub valve tuaj yeem nthuav tawm kaum tawm billions. txawv kev hloov.
Yog li ntawd, yuav ua li cas xaiv lub valve zoo yuav tsum xav txog cov hauv qab no:
Ua ntej: ib duas valve lossis binary valve?
Hauv kev sib xyaw ntawm cov khoom siv thiab tus neeg sawv cev ntawm qhov projectile, qhov sib xyaw ntawm cov khoom siv mis yuav tsum raug txiav txim siab.Thaum tus neeg saib xyuas qhov projectile thiab cov ntsiab lus tau txau rau tib lub sijhawm, nws yog ib qho yooj yim los tsim cov tshuaj tua kab mob, thiab cov khoom siv lub cev tseem nyob, uas cuam tshuam rau cov neeg siv khoom.Tsis tuaj yeem siv 360 degrees, tsuas yog siv rau pem hauv ntej lossis rov qab.Volatile parabolic tus neeg sawv cev (propylene butane los yog dimethyl ether), lub siab yuav nce geometrically nrog rau qhov kub thiab txias, belongs rau cov khoom txaus ntshai, kev thauj mus los thiab kev cia khoom muaj cov cai nruj.
Tsis hais tus nqi, binary li qub muaj ntau yam zoo: piv txwv li:
Cov ntsiab lus tsis ncaj qha hu rau lub tank aerosol, tsim kev tiv thaiv rau cov khoom siv lub cev;
Txhua qhov ejection, hloov mus rau qhov sib txawv noj scene;
Lub tshuab nqus tsev lub hnab ua ntej sau, tuaj yeem ua rau irradiated los ntawm cobalt 60 tshuaj tua kab mob, cov mis yuav txo tau cov tshuaj tua kab mob, txo qhov ua xua;
Tsis tu ncua siab nyob rau hauv lub tank, ruaj khov ejection, cov khoom uas tsis muaj lub cev residue;
Nrog compressed cua los yog nitrogen, lub siab yuav luag tas li raws li qhov kub thiab txias, thiab cov kev xav tau rau kev thauj mus los thiab kev cia khoom kuj tsawg.
Thib ob: qhov kev xaiv ntawm cov khoom ntim ntim khoom ntim khoom?
Iron khob feem ntau yog 0.27mm tuab thiab txhuas khob yog 0.42mm tuab.Daim ntawv thov kev saib xyuas tus kheej feem ntau siv lub khob aluminium, uas ruaj khov dua thiab tsis tshua muaj corrosion.Qhov loj stability ntawm lub khob hlau yog zoo dua, thiab nws tsis yooj yim rau cuam tshuam los ntawm lub tank los yog khob sealing txheej txheem;
Thib peb: cov khoom siv gasket
Gaskets feem ntau muab faib ua cov gaskets sab hauv thiab sab nraud, cov ntaub ntawv muaj ntau yam, feem ntau: butyl, chloroprene, butyl, chloroprene, nitrile, chloroprene, polyurethane thiab lwm yam.Gasket shrinkage yuav cuam tshuam rau qia gasket haum, qee zaum ua rau to.Yog hais tias lub gasket nthuav tawm ntau dhau, lub valve qia qhov ntawm lub gasket tsis tuaj yeem raug thaum lub nozzle raug nias, uas yuav cuam tshuam rau kev txhaj tshuaj.Tom qab rov sim dua, kub tau sim nrog sib tov ntawm 75% ethanol thiab 25% isopentane, thiab qhov kev xaiv zoo tshaj plaws yog cov roj hmab ruaj khov ntawm NEOPRENE thiab BUNA.
Plaub: qia aperture
Qhov ntau thiab tsawg yog 0.35, 0.4, 0.46, 0.51, 0.61mm, thiab tus naj npawb ntawm qia qhov yog ib qho ntawm cov kev txiav txim siab ntawm qhov gushing.Tus naj npawb ntawm qia qhov tseem muaj nyob rau hauv ntau series, nrog rau 1,2,4,6 thiab txawm 8 qhov.
Thib tsib: ib sab ntawm lub qhov valve
Cov roj theem sab qhov yog nyob rau ntawm lub valve chamber lub cev, thiab nyob rau sab hauv tom qab lub valve raug kaw.Nws yog tsuas yog siv los ua kom cov nyhuv atomization, nce kev ruaj ntseg ntawm cov ntsiab lus ejection ntawm qee cov khoom hmoov, thiab ua rau kom cov khoom viscosity siab.Muaj nyob rau hauv ib qho thiab ob lub qhov tsim.
Number six: Straw length
Nyob rau hauv thawj qhov chaw yuav ua tau raws li lub valve ntev = tag nrho qhov siab ntawm lub hub - teem tus nqi.Qhov kawg valve ntev yuav tsum nyob rau hauv qab 1/3 ntawm lub semi-lub voj voog nyob rau hauv qab ntawm lub tank tom qab lub hauv qab ntawm straw yog stabilized los ntawm soaking.
Xav tias cov straws muaj qhov nthuav dav 3-6%, nws yog ib qho tseem ceeb kom paub meej tias qhov ntev tom qab kev sib raug zoo, thiab tau kawg, bevel txiav straws tsim kuj tuaj yeem pab me ntsis.
Nrog cov nyees khawm tsim nyog, lub valve xaiv tuaj yeem xa cov yam ntxwv ntawm aerosol rau cov neeg siv khoom.Raws li cov txheej txheem pob rau cov khoom lag luam, nws xav tau kev sib raug zoo thiab kev ntsuas kev ruaj ntseg los tsim cov khoom lag luam zoo!
