Flanged vs. Threaded Ball Valves: Phau Ntawv Qhia Txog Kev Xaiv

Qhov kev xaiv ntawm ib qhoflanged pob valvethiab ib qholub pob valve threadedyog ib qho kev txiav txim siab tseem ceeb hauv kev tsim kho uas nthuav dav tshaj li hom kev sib txuas xwb. Nws cuam tshuam ncaj qha rau kev ua tiav, kev nyab xeeb, kev saib xyuas lub neej, thiab tag nrho cov nqi ntawm koj lub kav dej. Txawm hais tias tus nqi thiab kev yooj yim feem ntau yog cov tsav tsheb pib, kev nkag siab tob txog cov yam ntxwv kev ua tau zoo yog qhov tseem ceeb rau kev xaiv zoo tshaj plaws.

Phau ntawv qhia no txav mus dhau qhov kev sib piv yooj yim los muab cov txheej txheem txheeb xyuas kom ntxaws, pab koj teev qhov kev sib txuas valve kom raug rau koj qhov kev xav tau siab, kev saib xyuas, thiab kev ua haujlwm.

Lub Tswv Yim Tsim Qauv Tseem Ceeb: Mus tas li vs. Pab Tau

Qhov sib txawv yog nyob rau hauv lub neej voj voog thiab kev pabcuam ntawm lub kaw lus.

Cov Pob Valves Uas Muaj Xov: Qhov Kev daws teeb meem me me, mus tas li

Iblub pob valve threadedsiv cov xov National Pipe Taper (NPT) los ntsia ncaj qha rau ntawm cov kav dej. Cov xov tapered tsim cov hlau-rau-hlau wedge uas, nrog kev pab ntawm sealant, tiv thaiv cov xau. Lub tswv yim tsim no nyiam compact, pheej yig, thiabfeem ntau yog cov chaw teeb tsa tas mus liqhov twg tsis xav tias yuav muaj kev sib cais.

Cov Flanged Ball Valves: Kev daws teeb meem zoo thiab siv tau zoo

Ibflanged pob valventa cov flanges machined uas tau bolted rau cov yeeb nkab flanges sib phim, nrog rau lub gasket compressed ntawm lawv los tsim ib lub foob. Qhov kev tsim no yog tsim raucov tshuab ua haujlwm tau zoo, siv tau yooj yim, thiab modularNws tso cai rau kev teeb tsa yooj yim, tshem tawm, thiab tshuaj xyuas yam tsis muaj kev hloov pauv ntawm lub kaw lus, ua rau nws yog tus qauv rau cov ntawv thov tseem ceeb.

Kev Sib Piv Txog Kev Tshawb Fawb: Kev Ua Tau Zoo Hauv Qab Kev Nyuaj Siab

Ib daim ntawv teev cov txiaj ntsig thiab qhov tsis zoo yooj yim xwb tsis txaus. Nov yog cov ntaub ntawv qhia txog cov yam tseem ceeb ntawm kev ua tau zoo.

1. Kev Muaj Peev Xwm Siab thiab Kub

• Kev Sib Txuas XovCov xov lawv tus kheej yog qhov ua rau tsis ua haujlwm thaum muaj kev ntxhov siab. Lawv yooj yim rau kev ntxhov siab corrosion tawg thiab tuaj yeem xau thaum muaj kev hloov pauv thermal loj. Zoo tshaj plaws rauKev ntsuas qib 800 thiab qis dua, feem ntau nyob rau hauv daim ntawv thov nyob rau hauv200-300 PSI.
• Kev Sib Txuas FlangedCov kev sib txuas bolted faib cov khoom thauj kom sib npaug, thiab lub gasket foob ntsej muag-rau-lub ntsej muag yog qhov ruaj khov heev. Tsim los rau cov chav kawm siab txheem (ANSI Chav Kawm 150, 300, 600, 900, 1500, 2500), flanged li qub ntseeg tau tswj hwm cov siab tshaj 1000 PSI thiab cov kua kub siab.

2. Kev Teeb Tsa, Kev Saib Xyuas, thiab Tag Nrho Tus Nqi ntawm Kev Muaj (TCO)

Lub Valve Threaded TCO:

• Kev Teeb Tsa:Kev teeb tsa thawj zaug sai dua; xav tau cov sealant thiab cov txheej txheem threading kom raug.
• Kev Txij Nkawm:Qhov tsis zoo tshaj plaws. Feem ntau kev rho tawm yuav tsum tau muab lub valve thim rov qab rau ntawm cov yeeb nkab, uas ua tsis tau vim yog xeb lossis kev sib dhos ntawm lub kaw lus, ua rau yuav tsum tau txiav cov yeeb nkab kim heev.
• TCO:Tus nqi pib qis dua, tab sis muaj peev xwm ua rau muaj kev siv nyiaj ntau dua rau kev saib xyuas mus sij hawm ntev.

Flanged Valve TCO:

• Kev Teeb Tsa:Nyuaj dua; yuav tsum tau xaiv gasket kom raug, bolt zawm kom nruj, thiab cov nqi torque.
• Kev Txij Nkawm:Tsis muaj qhov sib piv. Lub valve tuaj yeem tshem tawm thiab nqa tawm ncaj qha rau kev pabcuam, hloov pauv, lossis tshuaj xyuas, txo qis lub sijhawm tsis ua haujlwm ntawm lub kaw lus.
• TCO:Kev nqis peev thawj zaug siab dua (valve, gaskets, bolts), tab sis qis dua cov nqi kho thiab lub sijhawm tsis ua haujlwm hauv cov kab ke tseem ceeb.

3. Kev Ncaj Ncees ntawm Lub System thiab Kev Siv Tau Zoo

Cov Li Qub Threaded Excel Hauv:

• Loj: Cov kav dej me me (**

Cov Li Qub Threaded Excel Hauv:

• Loj: Cov kav dej me me (2 nti thiab qis dua).
• Cov Ntawv Thov: Cov kav dej hauv tsev, HVAC, cov kav dej / cua qis, cov khoom siv OEM, thiab cov tshuab txhaj tshuaj uas qhov chaw txwv.
• Ib puag ncig: Cov txheej txheem ruaj khov nrog kev co tsawg kawg nkaus thiab kev hloov pauv thermal.

Cov Flanged Valves yog qhov tseem ceeb rau:

• Loj: 2 nti thiab siab dua (tus qauv), txawm hais tias feem ntau siv txog li 1/2 nti rau kev pabcuam tseem ceeb.
• Daim Ntawv Thov: Kev tsim roj thiab roj av, kev ua tshuaj lom neeg, kev tsim hluav taws xob, cov kav dej tiv thaiv hluav taws, cov tshuab ua pa, thiab txhua yam txheej txheem nrog cov xov xwm txaus ntshai.
• Ib puag ncig: Cov tshuab uas muaj kev co siab, kev nce siab ntawm lub zog, kev nthuav dav thermal, lossis xav tau kev cais tawm tas li.

Kev Txiav Txim Siab Matrix: Xaiv Qhov Kev Sib Txuas Zoo

Tshaj Li Qhov Tseem Ceeb: Cov Kev Xav Txog Kev Xaiv Tseem Ceeb

• Kev Xaiv Gasket: Rau cov flanged valves, lub gasket yog ib qho tseem ceeb heev. Cov khoom siv (piv txwv li, EPDM, PTFE, Graphite) yuav tsum sib xws nrog cov kua dej, qhov kub, thiab siab.
• Kev Teeb Tsa Kom Zoo: Cov xov NPT yuav tsum tau kaw kom zoo nrog cov xov sib xyaw lossis daim kab xev. Cov pob qij txha flanges yuav tsum tau bolted siv cov qauv torque sib law liag kom ntseeg tau tias muaj kev sib txhuam ntawm gasket thiab tiv thaiv kev xau.
• Kev Sib Xws ntawm Cov Khoom Siv: Xyuas kom tseeb tias cov khoom siv ntawm lub cev valve (WCB, CF8M, thiab lwm yam) thiab cov khoom siv sib xws nrog koj cov kua dej kom tsis txhob muaj kev xeb galvanic lossis kev puas tsuaj ntawm cov tshuaj lom neeg.

Xaus Lus: Ib Lo Lus Nug Txog Kev Xav Txog Lub Txheej Txheem

Qhov kev sib cav sib ceg ntawm flanged thiab threaded tsis yog hais txog qhov twg zoo dua, tab sis qhov twg tsim nyog rau koj lub system lub tswv yim.

• Xaiv lub pob valve uas muaj xov rau kev daws teeb meem pheej yig, me me, thiab yuav ruaj khov hauv cov kev pabcuam siab qis mus rau nruab nrab.
• Xaiv lub pob flanged rau kev siv siab, tseem ceeb, lossis kev saib xyuas ntau qhov twg kev ua haujlwm ntawm lub kaw lus, kev nyab xeeb, thiab kev ywj pheej ua haujlwm yog qhov tseem ceeb.
