Umehluko Wezinto ezibonakalayo
Insimbi Efojiwe:
Insimbi eyakhiwe ikhiqizwa ngokushisa amabhilidi ensimbi futhi iwabumbe ngaphansi kwengcindezi ephezulu. Le nqubo ithuthukisa ukwakheka kokusanhlamvu, okuholela emandleni aphakeme emishini, ukuqina, kanye nokumelana nezindawo ezinomfutho ophezulu/izinga lokushisa. Amabanga ajwayelekile ahlanganisaI-ASTM A105 (i-carbon steel)futhiI-ASTM A182 (insimbi engagqwali).
Insimbi yokusakaza:
Insimbi yensimbi yakhiwa ngokuthela insimbi encibilikisiwe esikhunjeni. Nakuba kubiza kakhulu izimo eziyinkimbinkimbi, ingase ibonise i-porosity noma ukungahambisani, inciphise ukusetshenziswa kwayo ezimweni ezimbi kakhulu. Amabanga ajwayelekile afaka i-ASTM A216 WCB (i-carbon steel) ne-ASTM A351 CF8M (insimbi engagqwali).
Umehluko Obalulekile Phakathi Kwevalve Yensimbi Efojiwe kanye namaValuvu Ensimbi Yabalindi
| Ipharamitha | Amavalvu Ensimbi Akhiwe | Amavalvu Ensimbi |
| Ububanzi besayizi | Okuncane (DN15–DN200, ½”–8″) | Okukhudlwana (DN50–DN1200, 2″–48″) |
| Isilinganiso Sokucindezela | Okuphakeme (Ikilasi 800–4500) | Okumaphakathi (Ikilasi 150–600) |
| Izinga lokushisa | -29°C kuya ku-550°C | -29°C kuya ku-425°C |
| Izinhlelo zokusebenza | Amapayipi anengcindezi ephezulu, izindawo zokuhlanza | Amasistimu okucindezela okuphansi/okumaphakathi, amanzi |
Izigaba zevalvu
Amavalvu Ensimbi Akhiwe
1. Amavalvu Esango Lensimbi Efojiwe (Ikilasi 800): Idizayini ehlangene yokuhlukaniswa kwengcindezi ephezulu kumasistimu kawoyela/igesi.
2. Forged Steel Globe Valves: Ukulawula ukugeleza okunembile kuzinkonzo zesitimu noma zamakhemikhali.
3. Amavalvu Okuhlola Ensimbi Efojiwe: Vimbela ukubuyela emuva kuma-compressor noma amaphampu (izinhlobo ze-swing/lift).
4. Amavalvu Ebhola Enziwe Ngensimbi: Ukuvalwa okusheshayo kumapayipi e-hydrocarbon e-Class 800.
Amavalvu Ensimbi
1. Amavalvu Esango Lensimbi Yensimbi (Ikilasi 150–300): Ukuhlukaniswa koketshezi ngobuningi ekuhlanzeni amanzi.
2. Ama-valve e-Cast Steel Globe: Ukulawulwa kokugeleza okujwayelekile ezinhlelweni ze-HVAC.
3. I-Cast Steel Check Valves: Izixazululo ezingabizi kakhulu zezinsizakalo ezingabalulekile.
Kungani KhethaI-Class 800 Forged Steel Valves
Amavalvu ensimbi afojiwe ekilasi lama-800 amelana nezingcindezi ezifika kubha engu-1380 (20,000 psi) ku-38°C, okuwenza alungele:
- Izinsimbi zamafutha zasogwini
- Imigqa ye-steam enezinga eliphezulu lokushisa
- Izitshalo zokucubungula i-hydrogen
Isiphetho
Ama-valve ensimbi akhiwezihamba phambili ezindaweni ezinokucindezeleka okukhulu ngenxa yokwakhiwa kwazo okuqinile, kuyilapho ama-valve ensimbi ensimbi enikeza izixazululo zokonga zezinhlelo ezinkulu, ezinengcindezi ephansi. Ukukhetha uhlobo olulungile kuncike ezidingweni zokusebenza, isabelomali, namazinga emboni afana ne-ASME B16.34.
