1. Isixhobo sokusebenza

Ngokweendlela ezahlukeneyo zokusebenza, kuyimfuneko ukukhetha izixhobo ezinokumelana nokugqwala okuhle. Umzekelo, ukuba isixhobo samanzi anetyuwa okanye amanzi olwandle, idiski yevalvu ye-aluminium bronze ingakhethwa; Ukuba isixhobo samanzi sine-asidi enamandla okanye i-alkali, i-tetrafluoroethylene okanye i-fluororubber ekhethekileyo ingakhethwa njengezinto zesihlalo sevalvu.

2.Uxinzelelo olusebenzayo kunye nobushushu

ivalvu yebhabhathane yetywina yerabhakufuneka isebenze ngokuqhelekileyo ngaphakathi koxinzelelo oluchaziweyo lokusebenza kunye nomgangatho wobushushu, ngoko ke kuyimfuneko ukukhetha izixhobo ezinamandla aneleyo kunye nokumelana nobushushu.

3. Iimeko zokusingqongileyo

Cinga ngeemeko zokusingqongileyo apho ivalvu ikhoyo, ezinje ngomswakama, ityuwa etshizwayo, njl.njl., uze ukhethe izinto ezifanelekileyo. 

4. Izinto zomzimba weValve

Izinto zomzimba wevalvuivalvu yebhabhathane esisangqaziquka intsimbi engwevu ephoswe ngentsimbi, intsimbi ethambileyo, intsimbi ephoswe ngentsimbi, intsimbi engatyiwayo, njl. Phakathi kwazo, intsimbi engatyiwayo inentsebenzo engcono kakhulu, kodwa ixabiso liphezulu kakhulu. Ukuba ikwindawo enoxinzelelo oluphantsi, ukusebenza kwezinto zentsimbi ephoswe ngentsimbi kunokuthelekiswa noko kwezixhobo zentsimbi ephoswe ngentsimbi, kwaye ixabiso lokusebenzisa izinto zentsimbi ephoswe ngentsimbi liphantsi.

5. Izinto zesihlalo seValve

Izinto zokuhlala zeivalvu yebhabhathane yegiya lembunguziquka irabha kunye ne-fluoroplastics. Izitulo zeevalvu zerabha zingasetyenziswa kwiindawo ezibuthathaka ze-asidi kunye ne-alkaline ezifana namanzi, umphunga, kunye neoyile, kwaye zisebenza kakuhle ekuvaleni; Izitulo zeevalvu ze-Fluoroplastic zisetyenziswa kwiindawo ezibola kakhulu.

6. Izixhobo zediski yebhabhathane

Izixhobo zediski yebhabhathane kwiivalvu zebhabhathane ezenziwe ngesandla ziquka intsimbi ethambileyo kunye nentsimbi engatyiwayo. Ngamanye amaxesha, ukuze uzivumelanise neendawo ezintsonkothileyo zemidiya, kuyimfuneko ukusonga idiski yebhabhathane ngeglu okanye ngezinto zePTFE.

7. Izinto zomngxuma weValve

Uninzi lwazo zenziwe ngezinto zentsimbi engagqwaliyo, kwaye iimeko ezikhethekileyo zinokwenziwa ngokwezifiso ngokweemfuno.

8. Izinto zokuqhuba

Kukho iindlela ezimbini eziphambili zokusebenza ngesandla, isiphatho kunye nesixhaso seempethu. Izixhobo zesiphatho ziquka ikakhulu intsimbi ephosiweyo, intsimbi yekhabhoni, intsimbi engatyiwayo, i-aluminium alloy, njl.njl. Izinto ezisetyenziswa entlokweni yesixhaso seempethu ikakhulu yintsimbi ephosiweyo.

Ngamafutshane, ukhetho lomgangatho wezintoivalvu yebhabhathane yesandlakufuneka siqwalasele ngokupheleleyo izinto ezifana nendawo yokusebenza, uxinzelelo lokusebenza kunye nobushushu, iimeko zokusingqongileyo, kunye nezinto zomzimba wevalvu, isihlalo sevalvu, idiski yebhabhathane, kunye nomngxuma wevalvu. Ukukhetha izinto ngokuchanekileyo kunokuqinisekisa ukusebenza okuqhelekileyo kunye nobomi benkonzo yeivalvu yebhabhathane yamanzi.
