Ukuhlohla
Ukuhlohla
Phawula!
I-valve yohlobo lwe-POV luhlelwe njenge-compressor overflow accessory (kungekhona njengesixhobo sokhuseleko). Yiyo loo nto ivalve yokhuseleko (umz. SFV) kufuneka ifakwe ukukhusela isixokelelwano kuxinzelelo olugqithisileyo.
Iifriji
Isebenza kwi-HCFC, i-HFC, i-R717 (i-Amonia) kunye ne-R744 (CO₂).
Iihydrocarbons ezinokutsha azikhuthazwa. Ivalve icetyiswa kuphela ukuba isetyenziswe kwiisekethe ezivaliweyo. Ngolwazi oluthe vetshe nceda uqhagamshelane noDanfoss.
Uluhlu lobushushu
POV: -50/+150 °C (-58/+302 °F)
Uluhlu loxinzelelo
Iivalvu zenzelwe ubuninzi. uxinzelelo olusebenzayo lwe-40 barg (580 psig).
Ukuhlohla
I-valve ye-POV isetyenziswe ngokubambisana ne-BSV yoxinzelelo lwangasemva lwe-valve yokhuseleko oluzimeleyo kwaye yenzelwe ngokukodwa ukukhusela i-compressors ngokuchasene noxinzelelo olugqithisileyo (umzobo 5).
Jonga incwadana yobugcisa ngemiyalelo yokufakela eyongezelelweyo.
Ivalve kufuneka ifakwe kunye nendlu yasentwasahlobo phezulu (umzobo 1). Ngokunyuka kwe-valve kubalulekile ukuphepha impembelelo yoxinzelelo lwe-thermic kunye ne-dynamic (vibrations).
Ivalve yenzelwe ukumelana noxinzelelo oluphezulu lwangaphakathi. Nangona kunjalo, inkqubo yombhobho kufuneka yenzelwe ukuphepha imigibe yolwelo kunye nokunciphisa umngcipheko woxinzelelo lwe-hydraulic obangelwa kukwandiswa kwe-thermal. Kufuneka kuqinisekiswe ukuba i-valve ikhuselwe kuxinzelelo oludlulayo "njengesando solwelo" kwinkqubo.
Indlela yokuhamba ecetyiswayo
Ivalve kufuneka ifakwe kunye nokuhamba ukuya kwikhowuni yevalve njengoko kubonisiwe lutolo olukwifigi. 2.
Ukuqukuqela kwelinye icala akwamkelekanga.
Ukuwelda
Umphezulu kufuneka ususwe phambi kwe-welding (umzobo 3) ukukhusela umonakalo kwi-O-rings phakathi kwe-valve body and top, kunye ne-teflon gasket kwisihlalo sevalve. Musa ukusebenzisa izixhobo ezinesantya esiphezulu sokuqhawula kunye nokudibanisa kwakhona. Qinisekisa ukuba igrisi ekwibholithi icocekile phambi kokuba udityaniswe kwakhona.
Kuphela izixhobo kunye neendlela ze-welding ezihambelana nezixhobo zezindlu zevalve kufuneka zisetyenziswe. I-valve kufuneka ihlambuluke ngaphakathi ukuze isuse i-debris ye-welding ekugqityweni kwe-welding kwaye ngaphambi kokuba i-valve iphinde ihlanganiswe.
Gwema i-welding debris kunye nokungcola kwimicu yezindlu kunye nephezulu.
Ukususa umphezulu kunokushiywa ngaphandle kokuba:
Iqondo lobushushu kwindawo ephakathi komzimba wevalvu kunye nomphezulu ngokunjalo nakwindawo ephakathi kwesitulo kunye nekowuni yeteflon ngexesha lewelding ayidluli +150 °C/+302 °F. Eli qondo lobushushu lixhomekeke kwindlela yokuwelda ngokunjalo nakuwuphi na ukupholisa umzimba wevalve ngexesha lokuwelda ngokwawo (ukupholisa kunokuqinisekiswa ngu, kuba example, ukusonga ilaphu elimanzi kumzimba wevalvu). Qinisekisa ukuba akukho kungcola, i-welding debris njl.njl ukungena kwi-valve ngexesha lenkqubo ye-welding.
Qaphela ukuba ungonakalisi iringi ye-teflon cone.
Indlu yevalve kufuneka ikhululeke kuxinzelelo (imithwalo yangaphandle) emva kokufakwa.
INdibano
Susa inkunkuma ye-welding kunye naluphi na ukungcola kwimibhobho kunye nomzimba wevalvu phambi kokudibanisa.
Ukuqiniswa
Qinisa phezulu kunye ne-torque wrench kumaxabiso aboniswe kwitheyibhile (umzobo 4). Musa ukusebenzisa izixhobo ezinesantya esiphezulu sokuqhawula kunye nokudibanisa kwakhona. Qinisekisa ukuba igrisi ekwibholithi icocekile phambi kokuba udityaniswe kwakhona.
Imibala kunye nokuchongwa
Ukuchongwa okuchanekileyo kwevalve kwenziwa nge-ID yeleyibhile phezulu, kunye ne-stampukubetha kumzimba wevalvu. Umphezulu wangaphandle wendlu yevalve kufuneka uthintelwe ngokuchasene ne-corrosion kunye nengubo efanelekileyo yokukhusela emva kokufakwa kunye nokudibanisa.
Ukukhuselwa kweleyibhile yesazisi xa upeyinta ivalve kuyacetyiswa.
Kwiimeko zamathandabuzo, nceda uqhagamshelane noDanfoss. U-Danfoss akalwamkeli uxanduva lweempazamo kunye nezinto ezishiyiweyo. I-Danfoss Industrial Refrigeration inelungelo lokwenza utshintsho kwiimveliso kunye neenkcukacha ngaphandle kwesaziso sangaphambili.
