Ukuqonda iBellow Seal Globe Valves
AIvalve yeglowubhu yetywina ebhobhozayosisivalo esikhethekileyo sokuvala eyenzelwe ukuphelisa ukuvuza kwesikhondo kwizicelo ezibalulekileyo. Ngokungafaniyo neevalvu zeglowubhu ezipakishiweyo, isebenzisa indibano yentsimbi yentsimbi edityaniswe kwisiqu kunye nomzimba wevalvu, isenza itywina le-hermetic. Olu luyilo lubalulekile ekuphatheni izinto eziyityhefu, ezidlekayo, okanye ezicoceke kakhulu apho ukukhutshwa kwembacu kungamkelekanga.
Amacandelo aphambili eBellow Seal Globe Valves
1. Indibano yeBellows
- Izinto:Insimbi engenasici (SS316/316L), i-Inconel 625, okanye iHastelloy C276
- Uyilo:Ii-convolutions ezininzi (8-12 iileya) ze-10,000+ ukuqina komjikelo
- Umsebenzi:Ukucinezela / ukwandisa ngexesha lokusebenza kwevalvu ngelixa ugcina ingqibelelo yesitywina
2. Umzimba weValve
- Umlinganiselo woxinzelelo:Iklasi 150 ukuya kwiKlasi 2500 (ANSI/ASME B16.34)
- Phelisa uQhagamshelwano:Flanged (RF/RTJ), socket weld, okanye buttweld
- Uluhlu Lwexesha:-196°C ukuya ku-550°C (cryogenic ukuya kubushushu obuphezulu)
3. Isiqu kunye neDiskhi
- Indibano ye-stem-disc edibeneyo yokwenziwa kolungelelwaniso
- Ukuqina komphezulu (Stellite 6 coating) ukwenzela ukuxhathisa i-abrasion
4. Isitywina sesibini (Ugcino)
- Izangqa zokupakisha zegraphite ngezantsi kwemvulo njengokusilela-ekhuselekileyo
Isebenza njani iBellow Seal Globe Valve
Inyathelo 1: Ukuvula iValve
Xa ivili lesandla lijikeleziswa ngasekunene:
- Isiqu siphakama, siphakamisa idiski kwisihlalo
- I-Bellows compress axially, igcina ingqibelelo yetywina
Inyathelo 2: Ukuvala iValve
Ujikelezo lwewotshi:
- I-Stem inyanzelisa idiski ngokuchasene nesihlalo, ukumisa ukuhamba
- I-Bellows idlulela kubude bokuqala
Inyathelo lesi-3: UThintelo lokuvuza
Isenzo sokutywina kabini:
- Itywina lokuqala: Indlela yokuvuza yebloko yeBellows block
- Isitywina sesibini: Ukupakishwa kweGraphite (i-API 622 iyahambelana)
Izinto eziluncedo ngaphezu kweeValufa zeGlobe eziMgangatho
| Uphawu | Bellow Seal Globe iValve | Ipakishwe iValve yeGlobe |
|---|---|---|
| Ukuvuza kwesiqu | Azikho izinto ezikhutshwayo ezibalekayo (ISO 15848-1 TA-Luft) | Ukuya kuthi ga kwi-500 ppm ukuvuza |
| Isondlo | Akukho ukupakisha endaweni efunekayo | Ukugcinwa kokupakishwa konyaka |
| Usetyenziso | Iinkqubo ezinobungozi, eziphakamileyo, ezicocekileyo | Iinkonzo zamanzi ngokubanzi/umphunga |
Izicelo zoShishino
1. Ukwenziwa kweMichiza
- Izityalo ze-Chlor-alkali (isiqulatho segesi yeklorine)
- Imveliso ye-Pharmaceutical API
2. I-oyile neGesi
- iiyunithi ze-alkylation ze-HF
- Ukudluliselwa kwe-LNG cryogenic (-162°C)
3. Ukuveliswa kwamandla
- Ukwahlulwa kwamanzi kwibhoyila
- Iinkqubo zokugqitha i-injini yomphunga
Iikhrayitheriya zokuKhetha
1. Uhlobo lweBellows
- Izafobe zoMgangatho:Uxinzelelo oluphezulu (i-ASME Class 1500+)
- Welded Bellows:Imidiya eyonakalisayo (umbane ogqityiweyo)
2. Iimpawu zokuhamba
- Ipesenti elinganayo vs. ukuqukuqela komgca kwizicelo zolawulo
3. Iziqinisekiso
- I-NACE MR0175 yenkonzo emuncu
- I-PED 2014/68/EU yeemarike zaseYurophu
Abavelisi beValve abaPhezulu baseTshayina
Abavelisi baseTshayina abafana noMvelisi weValve ye-NSW banikezela:
- I-API 602 / BS 1873 yoyilo oluhambelanayo
- I-30% yogcino lweendleko ngokuchasene neempawu zaseYurophu
- Uvavanyo lwesiko lokuvuza (ukubona ukuvuza kwe-helium)
ULondolozo lweyona Nkqubo iLungileyo
- Ukuhlolwa kwemivumbo rhoqo ngonyaka kwiintanda zokudinwa
- Ukuthanjiswa kwesiqu ngegrisi yobushushu obuphezulu
- Kuphephe ukubetha ngamandla (ubukhulu be-50 Nm yeevalvu ze-DN50)
