Izimpawu ze-ball valve ziyizithombe ezisetshenziswa emhlabeni wonkeimidwebo yobunjiniyela, I-P&ID (Imidwebo Yamapayipi kanye Nezinsimbi), kanye nemibhalo yobuchwepheshe. Lezi zimpawu ezijwayelekile zidlulisa ulwazi oluyinkimbinkimbi lwe-valve ngamafuphi, okuvumela ochwepheshe bomhlaba wonke ukuthi babone futhi bachaze ngokusheshaivalvu yebholaimisebenzi ezinhlelweni zoketshezi.
Iyini i-Ball Valve?
I-valve yebhola iyi-valve ejika ngekota esebenzisa ibhola elingenalutho, elijikelezayo ukulawula ukugeleza koketshezi. Lapho isibambo noma i-actuator iphendula ibhola ngama-degree angu-90, imbobo ihambisana nepayipi ukuze ivumele ukugeleza noma iqonde ngqo ukuze ilivimbele. Eyaziwa ngokuvaleka kwayo okuqinile, ukusebenza okusheshayo, kanye nokuqina, ama-valve ebhola asetshenziswa kabanzi ezimbonini eziningi.
Izimpawu ze-Ball Valve kuma-P&ID
Kumadayagramu e-P&ID, ama-valve ebhola amelelwa yinhlanganisela yezimpawu eziyisisekelo ezibonisa uhlobo lwazo, indlela yokuqalisa, kanye nemodi yokwehluleka. Uphawu oluvame kakhulu luhlanganisa indilinga enomugqa oqondile noma indilinga encane ngaphakathi, emele ibhola kanye nendlela yalo yokugeleza. Ama-modifiers engeziwe abonisa ukuthi i-valve isetshenziswa ngesandla, kagesi, i-pneumatic, noma inezinye izici ezikhethekile.
Izibonelo zifaka:
• I-Valve Yebhola Ejwayelekile: Indilinga enomugqa ovundlile kuyo.
• I-Ball Valve Enenjini: Uphawu olufanayo olunophawu “M” noma uphawu lwe-actuator kagesi.
• I-Solenoid Ball Valve: Ngokuvamile kuboniswa nophawu lwe-actuator kagesi.
Izinto Ezibalulekile Zezimpawu Zevalvu Yebhola
*(Kusekelwe kumazinga e-ISO/ANSI/ISA-S5.1)*
1. Isici Sebhola Eliyindilinga
Uphawu oluyinhloko luyindilinga emele ibhola eliyindilinga levalvu. Lesi sakhi sibonisa ukuthi ivalvu injalo yiniimbobo egcwele (imbobo egcwele)nomaimbobo encishisiwe (imbobo encishisiwe)- okubalulekile ekusebenzeni kahle kokulawula ukugeleza.
2. Imicibisholo Yokuqondisa Ukujikeleza
Imicibisholo ikhombisa ukujikeleza kokusebenza kwebhola:
↗: Ukujikeleza ngokwewashi = I-ValveVULIWE
↖: Ukujikeleza okuphikisana newashi = I-ValveKUVALIWE
*(Ukujikeleza okungu-90° kuyinto ejwayelekile kuma-valve ebhola aphenduka ngekota)*
3. Izimpawu Zokungena/Zokuphuma Kwezimbobo
Imigqa/imicibisholo imelela izindlela zokugeleza:
– Ukuxhumeka kwe-T okuqondile = Izindawo zokuhlangana kwamapayipi
– Imicibisholo evundlile = Isiqondiso sokugeleza esiyinhloko
– Izimpawu zonxantathu = Amachweba okucindezela
4. Izimpawu Zobuchwepheshe Ezengeziwe
Izichasiselo ezengeziwe zichaza:
– Ingcindezi yokusebenza (isb., i-PN16, iKlasi 150)
– Izinga lokushisa (°C/°F)
- Amakhodi ezinto (SS304, CS, PTFE)
– Uhlobo lwe-Actuator (olwenziwa ngesandla, oluqhutshwa umoya, olusebenza ngogesi)
Isibonelo Sesimboli Sevalvu Yebhola (Iskimu Sombhalo)
◯: Isici sebhola esinesibonisi sokujikeleza
↗↖: Izikhombisi-ndlela zokugeleza kokungena (kwesokudla) kanye nokukhipha (kwesobunxele)
*Qaphela: Izimpawu ze-P&ID zangempela zifaka izinkomba zesimo se-valve (evulekile/evaliwe/evulekile kancane)*
Amathiphu Okufunda Ama-P&ID Ngezimpawu Ze-Ball Valve
• Njalo bhekisela kukhiye wenganekwane noma uphawu oluqondene nomdwebo.
• Qaphela indlela yokusebenzisa kanye nendawo yokuhluleka.
• Qinisekisa indlela yokugeleza kanye nezinombolo zevalvu.
• Hlola ngokucophelela amashidi edatha e-valve kanye nemininingwane.
Kungani Izindinganiso Zezimpawu Zibalulekile Kubunjiniyela
- I-ISO 14617 / ANSI/ISA-S5.1qinisekisa ukuvumelana komhlaba wonke
- Kukhona ukwehluka okuqondene nemboni (uwoyela/igesi uma kuqhathaniswa nemithi)
- Kunciphisa amaphutha okufakwa ngo-68% (ucwaningo lwe-ASME 2023)
- Kubalulekile ukuthobela imithetho yezokuphepha ezindaweni eziyingozi
Icebiso Lochwepheshe:Njalo qhathanisa izinganekwane ezithile zephrojekthi – izimpawu zingahluka phakathi kwezindinganiso ze-ISO, DIN, kanye ne-ASME.
Kwenzelwe Onjiniyela Nochwepheshe
Lo mhlahlandlela wesibonakaliso se-ball valve uyakusiza:
✅ Nquma imidwebo ye-P&ID ngokushesha
✅ Thola izinhlobo zamavalvu ngokushesha (amavalvu ebhola vs. isango/imbulunga)
✅ Vimbela ukuhumusha okungekuhle okubizayo
✅ Landela izidingo zemibhalo ye-ISO 9001
*Ukuze uthole ukunemba, bheka izinhlelo zakamuva ze:*
- Izimpawu Zokusebenzisa Izinsimbi ze-ISA-S5.1
- Amazinga e-ISO 10628 P&ID
- Isaziso se-valve ye-ASME Y32.2.3
> Khumbula:Izimpawu zamavalvu ebhola ziwulimi olujwayelekile lwezinhlelo zokulawula uketshezi. Ukuzazi kahle kuqinisekisa ukuphepha kokusebenza kanye nokunemba kobuchwepheshe kuzo zonke izigaba zobunjiniyela.
Amavalvu Ebhola vs. Ezinye Izinhlobo Zamavalvu
Nakuba ama-valve ebhola eguquguquka, kubalulekile ukuwahlukanisa namanye ama-valve avamile:
• Amavalvu Esango:Isetshenziselwa isevisi yokuvula/ukuvala izinhlelo ezinomfutho ophezulu kodwa isebenza kancane.
• Amavalvu Embulunga:Kungcono ekulawuleni ukugeleza kwamanzi kanye nokulawula ukuhamba kwawo.
• Amavalvu Ovemvane:Incane futhi ingabizi kakhulu kumapayipi amakhulu kodwa ayisebenzi kahle uma ivaliwe ngomfutho ophezulu.
• Ama-Check Valve:Vumela ukugeleza ohlangothini olulodwa kuphela.
Ama-valve ebhola anikeza ukuvala okuphezulu nokusebenza okusheshayo uma kuqhathaniswa nezinye izindlela eziningi, ikakhulukazi ezisetshenziswayo ezihamba ngesivinini esikhulu.
Ulwazi olwengeziwe: Izimpawu zamanye ama-valve
Okulandelayo yisibonelo esilula sesinyeizimpawu zevalvu(ngesimo sombhalo):
Isiphetho
Izimpawu zevalvu yebholaziwulimi olujwayelekile kumadokhumenti obunjiniyela. Ukusetshenziswa okufanele kusekela ukucaca kohlelo, ukuphepha kokusebenza, kanye nokusebenza kahle kokugcinwa. Kungakhathaliseki ukuthi ukhetha, ufaka, noma unakekelaamavalvu ebhola, ukuqonda lezi zimpawu kubalulekile.
