Yeyiphi i-fluid media efanelekileyo kwi-check valve

Ivalvu yokujonga sisixhobo esibalulekileyo sokulawula ulwelo, uluhlu lwayo lokusetyenziswa lubanzi, lufanelekile kwiindidi ezahlukeneyo zemidiya yolwelo. Oku kulandelayo sisishwankathelo esineenkcukacha sendlela yokujonga ulwelo esebenza kwivalvu yokujonga:

Okokuqala, imidiya eqhelekileyo yolwelo

1. Ulwelo oluphakathi

Amanzi: Iivalvu zokuhlola zisetyenziswa kakhulu kwiinkqubo zokuhambisa amanzi kunye nokukhupha amanzi ukuze kuthintelwe ukubuya kwamanzi amdaka okanye ukubuya kwamanzi.

Ioyile: kuquka ioyile yokuthambisa, ioyile ye-hydraulic, njl.njl., ivalvu yokujonga inokuthintela ukubuya kwe-oyile kwaye ikhusele izixhobo ekonakalisweni.

I-asidi lye: Kwishishini leekhemikhali, iivalvu zokujonga zingasetyenziselwa ukukhupha i-asidi kunye ne-alkali corrosive media.

Ezinye izinto ezilulwelo: ezifana ne-asidi, i-lye kunye nezinye izinto ezilulwelo ezineempawu ezikhethekileyo, ivalvu yokujonga nayo ifanelekile, kodwa kuyimfuneko ukukhetha izinto ezifanelekileyo kunye nesakhiwo ngokweempawu zesixhobo.

2. Igesi ephakathi

Umoya: Ivalvu yokujonga ithintela ukubuya komoya kwinkqubo yoxinzelelo lomoya.

I-nitrogen, ioksijini kunye nezinye iigesi zoshishino: kwisinyithi, i-metallurgy, i-petrochemical kunye nezinye izimboni, iivalvu zokujonga zisetyenziselwa ukuthintela ukubuyela kwegesi zoshishino.

Igesi: njengegesi, igesi yendalo, njl.njl., ivalvu yokujonga ifakwe ekupheleni kombhobho wegesi ukuthintela ukubuya kwegesi nokuqinisekisa ukhuseleko lwabasebenzisi.

3. Isixhobo somphunga

Ubushushu obuphantsi, ubushushu obuphakathi, umphunga wobushushu obuphezulu: Ivalvu yokujonga idlala indima kwinkqubo yomphunga ukuthintela ukubuya komphunga kunye nehamile yamanzi, ikhusela izixhobo ekonakalisweni.

Okwesibini, i-medium ekhethekileyo yolwelo

Amanzi amdaka kunye namanzi amdaka: Kwiinkqubo zokucocwa kwamanzi amdaka kunye nokukhupha amanzi amdaka, iivalvu zokujonga zisetyenziselwa ukuthintela ukubuya kwamanzi amdaka kunye namanzi amdaka kunye nokukhusela okusingqongileyo kunye nezixhobo.

Amanzi olwandle: Iivalvu zokuhlola zingasetyenziswa kwiinkqubo zokukhupha amanzi olwandle ukuze zimelane nokugqwala kunye nokukhukuliseka kwamanzi olwandle.

Iikhemikhali zegrisi kunye nezomeleleyo: Kwiimeko ezithile zoshishino, ivalvu yokujonga ingasetyenziselwa ukukhupha iikhemikhali zegrisi kunye nezomeleleyo kunye nezinye izinto ezisetyenziswayo.

Okwesithathu, intsimi yesicelo

Iindawo zokusetyenziswa kweevalvu zokujonga zigubungela phantse zonke iindawo apho kuyimfuneko ukuthintela ukubuya kwemidiya, kuquka kodwa kungaphelelanga apho:

Ubomi basekhaya: njengokuhambisa amanzi kunye nenkqubo yokukhupha amanzi, iplagi yokufudumeza amanzi, umatshini wokuhlamba izitya kunye nomatshini wokuhlamba iimpahla kunye nezinye izixhobo zasekhaya.

Imveliso yemizi-mveliso: efana neekhemikhali, ipetroliyam, isinyithi kunye nezinye iimizi-mveliso kwinkqubo yemibhobho.

Iinkqubo ze-Hvac: ezifana neepayipi zokuhambisa amanzi ashushu kunye neenkqubo zokufudumeza.

Inkqubo yegesi: njengesiphelo sepayipi yegesi okanye yegesi yendalo.

Amasimi amatsha amandla: njengeenkqubo zamanzi ashushu elanga, iinkqubo zamandla omoya, njl.

Ukhuseleko lokusingqongileyo: njengokucoca amdaka, ukutshisa inkunkuma kunye nezinye iiprojekthi zokukhusela okusingqongileyo.

Ngamafutshane, ivalvu yokujonga ifanelekile kwiindidi ezahlukeneyo zemidiya yolwelo, kuquka imidiya yolwelo eqhelekileyo, igesi kunye nomphunga, kunye nenkunkuma ekhethekileyo, amanzi amdaka, amanzi olwandle, igrisi kunye neekhemikhali ezinamandla aphakathi kunye nezinye izinto zokujonga. Xa ukhetha ivalvu yokujonga, izinto ezifanelekileyo, isakhiwo kunye nomzekelo kufuneka zikhethwe ngokweempawu zemidiya yokujonga, uxinzelelo lokusebenza, ubushushu kunye nezinye iimeko.
