POV Compressor Overflow Valve
Kev teeb tsa
Kev teeb tsa
Nco tseg!
Valve hom POV yog categorized li compressor overflow accessory (tsis yog ib qho kev nyab xeeb accessory). Yog li ntawd, lub valve muaj kev nyab xeeb (xws li SFV) yuav tsum tau nruab los tiv thaiv lub cev tiv thaiv kev kub ntxhov ntau dhau.
Tub yees
Muaj feem xyuam rau HCFC, HFC, R717 (Ammonia) thiab R744 (CO₂).
Flammable hydrocarbons tsis pom zoo. Lub valve tsuas yog pom zoo rau siv nyob rau hauv kaw circuits. Yog xav paub ntxiv thov hu rau Danfoss.
Qhov kub thiab txias
POV: -50 / + 150 ° C (-58 / + 302 ° F)
Siab ntau
Cov li qub yog tsim los rau max. Ua haujlwm siab ntawm 40 barg (580 psig).
Kev teeb tsa
POV valve yog siv ua ke nrog BSV rov qab siab ywj siab kev nyab xeeb nyem valve thiab tshwj xeeb tsim los tiv thaiv compressors tiv thaiv ntau dhau (daim duab 5).
Saib daim ntawv qhia kev rau cov lus qhia ntxiv txog kev teeb tsa.
Lub valve yuav tsum tau nruab nrog lub caij nplooj ntoos hlav vaj tse upwards (daim duab 1). Los ntawm kev txhim kho ntawm lub valve nws yog ib qho tseem ceeb kom tsis txhob muaj kev cuam tshuam ntawm thermal thiab dynamic kev nyuaj siab (kev vibrations).
Lub valve yog tsim los tiv thaiv lub siab sab hauv. Txawm li cas los xij, cov kav dej yuav tsum tau tsim kom tsis txhob muaj cov cuab yeej ua kua thiab txo qhov kev pheej hmoo ntawm hydraulic siab los ntawm thermal expansion. Nws yuav tsum tau ua kom ntseeg tau tias lub valve raug tiv thaiv los ntawm kev hloov pauv siab xws li "kua rauj" hauv qhov system.
Pom zoo ntws kev taw qhia
Lub valve yuav tsum tau nruab nrog ntws mus rau lub valve lub khob hliav qab raws li qhia los ntawm xub xub ntawm daim duab. 2.
Flow nyob rau hauv qhov opposite direction yog tsis tau.
Vuam
Sab saum toj yuav tsum tau muab tshem tawm ua ntej vuam (daim duab 3) los tiv thaiv kev puas tsuaj rau O-rings ntawm lub valve lub cev thiab sab saum toj, nrog rau cov teflon gasket nyob rau hauv lub rooj zaum valve. Tsis txhob siv cov cuab yeej siab ceev rau kev rhuav tshem thiab rov ua dua. Nco ntsoov tias cov roj ntawm cov bolts tsis zoo ua ntej rov ua dua.
Tsuas yog cov ntaub ntawv thiab cov txheej txheem vuam sib haum nrog cov khoom siv hauv lub valve yuav tsum tau siv. Lub valve yuav tsum tau muab ntxuav sab hauv kom tshem tawm cov khib nyiab thaum ua tiav ntawm vuam thiab ua ntej lub valve rov ua haujlwm.
Tsis txhob vuam cov khib nyiab thiab av hauv cov xov ntawm lub tsev thiab sab saum toj.
Tshem tawm sab saum toj tuaj yeem tshem tawm yog tias:
Qhov kub hauv thaj tsam ntawm lub cev lub cev thiab sab saum toj nrog rau hauv thaj tsam ntawm lub rooj zaum thiab lub khob teflon thaum vuam tsis pub tshaj + 150 ° C / + 302 ° F. Qhov ntsuas kub no nyob ntawm txoj kev vuam zoo li ntawm qhov txias ntawm lub valve lub cev thaum lub vuam nws tus kheej (txias tuaj yeem ua kom ntseeg tau los ntawm, rau example, qhwv ib daim ntaub ntub nyob ib ncig ntawm lub valve lub cev). Nco ntsoov tias tsis muaj av, vuam khib nyiab thiab lwm yam nkag mus rau hauv lub valve thaum lub sij hawm vuam txheej txheem.
Ceev faj tsis txhob ua rau lub nplhaib teflon cone puas.
Lub valve vaj tsev yuav tsum tsis txhob muaj kev ntxhov siab (sab nraud loads) tom qab kev teeb tsa.
Kev sib dhos
Tshem tawm cov khib nyiab thiab cov av ntawm cov kav dej thiab lub cev valve ua ntej sib dhos.
Tightening
Tighten sab saum toj nrog lub torque ciaj ntswj mus rau qhov tseem ceeb ntawm lub rooj (daim duab 4). Tsis txhob siv cov cuab yeej siab ceev rau kev rhuav tshem thiab rov ua dua. Nco ntsoov tias cov roj ntawm cov bolts tsis zoo ua ntej rov ua dua.
Xim thiab kev txheeb xyuas
Kev txheeb xyuas meej ntawm lub valve yog ua los ntawm daim ntawv lo ID nyob rau sab saum toj, nrog rau los ntawm stampnyob rau hauv lub cev valve. Sab nraud ntawm lub valve vaj tse yuav tsum tau tiv thaiv corrosion nrog ib tug haum tiv thaiv txheej tom qab installation thiab sib dhos.
Kev tiv thaiv ntawm daim ntawv ID thaum pleev xim lub valve raug pom zoo.
