Izimpawu ze-Valve 101: Ukuqonda Izinhlobo Eziyinhloko, Amazinga, kanye Nezicelo Kuma-P&ID Diagrams

Ziyini Izimpawu Zevalvu

Izimpawu zamavalvu ziyizithombe ezijwayelekile ezisetshenziswa kuImidwebo Yamapayipi kanye Nezinsimbi (P&ID)ukukhombisa uhlobo, umsebenzi, kanye nokusebenza kwama-valve ngaphakathi kwesistimu. Lezi zimpawu zinikeza "ulimi" olujwayelekile konjiniyela, abaklami, kanye nochwepheshe ukuze baxhumane nezinhlelo zamapayipi eziyinkimbinkimbi ngempumelelo.

Kungani Izimpawu Zevalvu Zibalulekile

1. Ukucaca Emklamo: Susa ukungaqondakali kwemidwebo yobuchwepheshe.

2. Ukumiswa Komhlaba Wonke: Landela amazinga e-ISO, ANSI, noma e-ISA ukuze uthole ukuvumelana.

3. Ukuphepha Nokusebenza Kahle: Qinisekisa ukukhetha okufanele kwevalvu kanye nokusebenza kwesistimu.

4. Ukuxazulula izinkinga: Yenza kube lula ukulungisa nokulungisa ukusebenza.

Izimpawu Ezivamile Zevalvu Zichaziwe

1. Uphawu lwe-Ball Valve

– Indilinga enomugqa oqondile odlula phakathi nendawo.

– Imele ikhono lokuvala ngokushesha; livame kakhulu ezinhlelweni zikawoyela, igesi, kanye namanzi.

2. Uphawu lweValvu Yesango

– Unxantathu obheke phezulu/phansi phakathi kwemigqa emibili evundlile.

– Kubonisa ukulawula ukunyakaza okuqondile kokugeleza okugcwele noma ukuhlukaniswa.

3. Uphawu Lokuhlola I-Valve

– Umcibisholo omncane ngaphakathi kwendilinga noma isimo “se-clapper”.

– Kuqinisekisa ukugeleza okuqondile; kuvimbela ukugeleza emuva kwamapayipi.

4. Uphawu lwe-Butterfly Valve

– Imigqa emibili evundlile ehlangana nendilinga.

– Isetshenziselwa ukugoqa; ivame kakhulu ezinhlelweni ezinobukhulu obukhulu nezinomfutho ophansi.

5. Uphawu lwe-Globe Valve

– Isimo sedayimane ngaphakathi kwendilinga.

– Yakhelwe ukulawula ukugeleza okunembile ezisetshenziswayo ezinomfutho ophezulu.

Izindinganiso Eziyinhloko Zezimpawu Zevalvu

- I-ISO 14691: Icacisa izimpawu zamavalvu ezijwayelekile zezinhlelo zezimboni.

- I-ANSI/ISA 5.1: Izimpawu ze-P&ID zibusa e-US

- I-DIN 2429: Izinga laseYurophu lemidwebo yobuchwepheshe.

Amathiphu Okufunda Izimpawu Zevalvu

- Njalo bheka inganekwane ye-P&ID ukuze uthole ukuhlukahluka okuqondene nephrojekthi ethile.

- Qaphela izinhlobo ze-actuator (isb., ngesandla, emoyeni, kagesi) ezixhunywe nezimpawu.

Ukuqondaizimpawu zevalvukubalulekile ekuklanyweni kwesistimu okunembile, ukuthobela imithetho yokuphepha, kanye nokubambisana okungenazinkinga phakathi kwamaqembu obunjiniyela.ivalvu yebholaumsebenzi wokuvala nomaivalvu yomhlabaindima ka-throttling, ukuqonda leziizimpawukuqinisekisa ukwenziwa kwephrojekthi okuphumelelayo.
