Iyiphi i-fluid media efanele i-check valve

I-valve yokuhlola iyithuluzi elibalulekile lokulawula uketshezi, ububanzi bokusetshenziswa kwayo bubanzi, ifanelekela izinhlobo ezahlukene zemidiya yoketshezi. Okulandelayo isifinyezo esinemininingwane sendlela yoketshezi esebenza ku-valve yokuhlola:

Okokuqala, imidiya evamile yoketshezi

1. Uketshezi oluphakathi

Amanzi: Ama-valve okuhlola asetshenziswa kabanzi ezinhlelweni zokuhlinzeka ngamanzi kanye nokukhipha amanzi ukuze kuvinjelwe ukugeleza kwamanzi noma ukugeleza kwamanzi emuva.

Uwoyela: okuhlanganisa uwoyela wokugcoba, uwoyela we-hydraulic, njll., i-valve yokuhlola ingavimbela ukugeleza kwe-oyela emuva futhi ivikele imishini ekulimaleni.

I-asidi lye: Embonini yamakhemikhali, ama-check valve angasetshenziswa ukukhipha i-asidi kanye ne-alkali corrosive media.

Ezinye izinto eziwuketshezi: njenge-asidi, i-lye kanye nezinye izinto eziwuketshezi ezinezakhiwo ezikhethekile, i-valve yokuhlola nayo iyafaneleka, kodwa kuyadingeka ukukhetha izinto ezifanele kanye nesakhiwo ngokwezici ze-medium.

2. Igesi ephakathi nendawo

Umoya: I-valve yokuhlola ivimbela ukubuyela emuva komoya ohlelweni lokucindezela umoya.

I-nitrogen, i-oxygen kanye nezinye igesi zezimboni: ensimbini, ensimbini, ephethroli nakwezinye izimboni, ama-valve okuhlola asetshenziswa ukuvimbela ukubuyela emuva kwegesi yezimboni.

Igesi: njengegesi, igesi yemvelo, njll., i-valve yokuhlola ifakwa ekugcineni kwepayipi legesi ukuvimbela ukugeleza kwegesi emuva nokuqinisekisa ukuphepha kwabasebenzisi.

3. I-steam medium

Ukushisa okuphansi, izinga lokushisa eliphakathi, umusi ophakeme: I-valve yokuhlola idlala indima ohlelweni lomusi ukuvimbela ukugeleza komusi kanye nesando samanzi, ivikela imishini ekulimaleni.

Okwesibili, i-medium ekhethekile yoketshezi

Indle namanzi angcolile: Ezinhlelweni zokuhlanza indle kanye nokukhipha amanzi angcolile, ama-valve okuhlola asetshenziswa ukuvimbela ukugeleza kwamanzi angcolile kanye namanzi angcolile futhi avikele imvelo kanye nemishini.

Amanzi olwandle: Ama-valve okuhlola angasetshenziswa ezinhlelweni zokukhipha amanzi olwandle ukuze amelane nokugqwala nokuguguleka kwamanzi olwandle.

Amakhemikhali anamafutha naphakathi nendawo: Ezimweni ezithile zezimboni, i-valve yokuhlola ingasetshenziswa ukukhipha amakhemikhali anamafutha naphakathi nendawo kanye nezinye izinto ezisetshenziswayo.

Okwesithathu, insimu yesicelo

Izindawo zokusetshenziswa kwama-check valve zimboza cishe zonke izindawo lapho kudingeka khona ukuvimbela ukubuyela emuva kwe-media, okuhlanganisa kodwa kungagcini lapho:

Impilo yasekhaya: njengohlelo lokuphakelwa kwamanzi kanye nokukhipha amanzi, indawo yokucisha isifudumezi samanzi, umshini wokuwasha izitsha kanye nomshini wokuwasha kanye nezinye izinto zasekhaya.

Ukukhiqizwa kwezimboni: njengamakhemikhali, uphethiloli, i-metallurgy kanye nezinye izimboni ohlelweni lwamapayipi.

Izinhlelo ze-Hvac: njengezinhlelo zokuhambisa amanzi ashisayo kanye nokushisa.

Uhlelo lwegesi: njengegesi noma ipayipi legesi yemvelo.

Amasimu amasha wamandla: njengezinhlelo zamanzi ashisayo elanga, izinhlelo zamandla omoya, njll.

Ukuvikelwa kwemvelo: njengokwelashwa kwendle, ukushiswa kwemfucuza kanye neminye imisebenzi yokuvikela imvelo.

Ngamafuphi, ivalvu yokuhlola ifanelekela izinhlobo ezahlukene zemidiya yoketshezi, okuhlanganisa imidiya evamile yoketshezi, igesi kanye neyomusi, kanye nendle ekhethekile, amanzi angcolile, amanzi olwandle, amafutha kanye namakhemikhali anamandla aphakathi kanye nezinye izinto zokusebenzisa. Lapho ukhetha ivalvu yokuhlola, izinto ezifanele, isakhiwo kanye nemodeli kufanele kukhethwe ngokuya ngezici zemidiya, ingcindezi yokusebenza, izinga lokushisa kanye nezinye izimo.
