Iimpawu zevalvu yebhola ziimpawu zemizobo ezisetyenziswa kwihlabathi liphelaimizobo yobunjineli, Imizobo yeP&ID (iiPiping kunye neZixhobo zoMbane), kunye namaxwebhu obuchwephesha. Ezi mpawu zisemgangathweni zidlulisela ulwazi oluntsonkothileyo lwevalvu ngokufutshane, zivumela iingcali zehlabathi ukuba zichonge kwaye zitolike ngoko nangokoivalvu yebholaimisebenzi kwiinkqubo zolwelo.
Yintoni iValve yeBhola?
Ivalvu yebhola yivalvu ejika ngekota esebenzisa ibhola engenanto, ejikelezayo ukulawula ukuhamba kolwelo. Xa isiphatho okanye i-actuator ijika ibhola ngama-90 degrees, imbobo ihambelana nombhobho ukuvumela ukuhamba okanye ukuthe nkqo ukuyivimba. Eyaziwa ngokuyivala ngokuqinileyo, ukusebenza ngokukhawuleza, kunye nokuqina, iivalvu zebhola zisetyenziswa kakhulu kumashishini amaninzi.
Iimpawu zeValve yeBhola kwi-P&IDs
Kwimizobo ye-P&ID, iivalvu zebhola zimelwe yindibaniselwano yeempawu ezisisiseko ezibonisa uhlobo lwazo, indlela yokuqalisa, kunye nemo yokusilela. Uphawu oluqhelekileyo luquka isangqa esinomgca othe tyaba okanye isangqa esincinci ngaphakathi, esimele ibhola kunye nendlela yayo yokuhamba. Ezinye iziguquli zibonisa ukuba ivalvu isetyenziswa ngesandla, ngombane, ngomoya, okanye inezinye iimpawu ezikhethekileyo.
Imizekelo ibandakanya:
• Ivalvu yeBhola eQhelekileyo: Isangqa esinomgca othe tye odlula kuso.
• Ivalvu yeBhola eneeMoto: Uphawu olufanayo olunophawu "M" okanye uphawu lwe-actuator yombane.
• Ivalvu yeBhola yeSolenoid: Idla ngokuboniswa ngophawu lwe-electromagnetic actuator.
Izinto ezibalulekileyo zeMpawu zeValve yeBhola
*(Ngokusekelwe kwiMigangatho ye-ISO/ANSI/ISA-S5.1)*
1. I-Circular Ball Element
Uphawu oluphambili luyisangqa esimele ibhola yesangqa yevalvu. Le nto ibonisa ukuba ivalvu injalo na.imbobo epheleleyo (izibuko elipheleleyo)okanyeimbobo encitshisiweyo (izibuko elincitshisiweyo)- kubalulekile ekusebenzeni kakuhle kolawulo lokuhamba kwamanzi.
2. Iintolo zeSikhokelo sokuJikelezisa
Iintolo zibonisa ukujikeleza kokusebenza kwebhola:
↗: Ukujikeleza ngokwewotshi = IvalvuIVULIWE
↖: Ukujikeleza ngokuphambeneyo = IvalvuIVALIWE
*(Ukujikeleza kwe-90° kuyinto eqhelekileyo kwiivalvu zebhola ezijika ikota)*
3. Iimpawu zeZibuko zokungena/zokuphuma
Imigca/iintolo zibonisa iindlela zokuhamba:
– Uqhagamshelo lwe-T oluthe nkqo = Iintambo zombhobho
– Iintolo ezithe tye = Icala eliphambili lokuhamba kwamanzi
– Iimpawu zenxantathu = Iiports zoxinzelelo
4. Iimpawu zoBugcisa ezongezelelweyo
Izichazi ezongezelelweyo zichaza:
– Uxinzelelo lokusebenza (umz., i-PN16, iKlasi 150)
– Uluhlu lobushushu (°C/°F)
- Iikhowudi zezinto (SS304, CS, PTFE)
– Uhlobo lwe-Actuator (ngesandla, ngomoya, ngombane)

*Qaphela: Iimpawu ze-P&ID zokwenyani ziquka izalathisi zesimo sevalvu (evulekileyo/evaliweyo/evulekileyo kancinci)*
Iingcebiso zokufunda ii-P&IDs ngeeMpawu zeBall Valve
• Soloko ubhekisa kwintsomi okanye kwisitshixo sophawu olubhekiselele kumzobo.
• Qaphela indlela yokusebenza kunye nendawo yokusilela.
• Qinisekisa indlela yokuhamba kwamanzi kunye neenombolo zevalvu.
• Jonga iinkcukacha zeevalvu kunye neenkcukacha zazo.
Kutheni iMigangatho yeSimboli ibalulekile kubuNjineli
- I-ISO 14617 / ANSI/ISA-S5.1qinisekisa ukuhambelana kwehlabathi
- Kukho umahluko othile kushishino (ioyile/igesi xa kuthelekiswa neyeza)
- Yehlisa iimpazamo zokufakela nge-68% (uphando lwe-ASME 2023)
