Kungani ukhethe ivalvu yokubuka? Yiziphi izinhlobo zamavalvu ezikhona?

Amavalvu okubuka kancane kancane abe yizinto ezibalulekile zokufaka amapayipi namavalvu ekwakhiweni kwepayipi lamanje. Anikeza iziqinisekiso zokuphepha kulo lonke ipayipi futhi anciphisa ngokungaqondile izingozi zokuphepha kanye nezindleko zohlelo lonke lwepayipi.

Amavalvu okubuka asetshenziselwa ukuqapha izimo zokukhiqiza ngesikhathi sangempela, ukuxazulula izinkinga nokuqinisekisa ukuphepha. Amavalvu okubuka asetshenziswa njalo (njengezibuko zokubona eziqondile kanye nezinkomba zokugeleza) awalawuli ukugeleza ngokwawo, kodwa ahlinzeka ngefasitela elibonakalayo epayipini.

Izinzuzo zokubuka ama-valve zibonakala kakhulu ezicini ezintathu:

1. Bheka ngqo isimo sokugeleza, umbala kanye nokungcoliswa koketshezi, igesi, umusi kanye nezinye izinto ezisetshenziswayo emgudwini.
2. Uma uhlelo luhlangabezana nokugeleza okungavamile, ukuvaleka noma ukungabikho kokugeleza, imbangela ingatholakala ngokushesha nge-valve yokubuka ukuthi ngabe ibangelwa yi-valve ngokwayo ebambekile, ukuwa kwe-valve core, noma izinkinga epayipini elingaphezulu.
3. Qinisekisa ukusebenza okuphephile kohlelo. Ezindaweni eziyingozi njengezitshalo zamakhemikhali, lusetshenziselwa ukuqapha abezindaba abashisa kakhulu, abagqwala kakhulu futhi abakhazimulayo kalula ukuvimbela izingozi zokuphepha ezibangelwa amazinga noma ukuvinjelwa koketshezi okungamanga.

Ama-valve ahlukene okubuka asetshenziswa ezindaweni ezahlukene zokusebenza. Enziwe ngensimbi yekhabhoni, afaneleka ezintweni ezivamile njengamanzi, umusi, kanye namafutha, kodwa awamelani nokugqwala.

Izinto zensimbi engagqwali

Yinto esetshenziswa kakhulu ukumelana nokugqwala futhi ifanelekela izinhlobo ezahlukene zezinto ezigqwalayo.

Insimbi ye-alloy kanye nezinto ezikhethekile zensimbi engagqwali

Ifanelekela izindawo ezinzima njengokushisa okuphezulu, umfutho ophezulu, kanye nokugqwala okunamandla.

Ifakwe upulasitiki noma i-fluorine

Ifanelekela izinto ezidla kakhulu njenge-asidi enamandla kanye nama-alkali aqinile.

So

• Imidiya engagqwali: Insimbi yekhabhoni iyinto ongayikhetha futhi engabizi kakhulu.
• Imidiya evamile ebolile: Insimbi engagqwali engu-304 noma engu-316 iyathandwa.
• I-media ebolile kakhulu noma ekhethekile: Kudingeka ama-valve noma ama-alloy akhethekile ane-fluorine.
• Imidiya yokushisa okuphezulu noma ephansi: Insimbi ekhethekile yokushisa okuphezulu noma ephansi kumele ikhethwe.
