1.Isixhobo sokusebenza

Ngokutsho kweendaba ezahlukeneyo zokusebenza, kuyimfuneko ukukhetha izinto ezinokumelana nokugqwala okulungileyo. Umzekelo, ukuba i-medium ngamanzi anetyuwa okanye amanzi olwandle, i-disc yevalve ye-aluminiyam yobhedu inokukhethwa; Ukuba i-medium yi-asidi eyomeleleyo okanye i-alkali, i-tetrafluoroethylene okanye i-fluororubber ekhethekileyo ingakhethwa njengesixhobo sesihlalo sevalve.

2.Uxinzelelo lomsebenzi kunye nobushushu

irabha itywina butterfly valveidinga ukusebenza ngokuqhelekileyo ngaphakathi koxinzelelo oluchaziweyo lokusebenza kunye noluhlu lweqondo lokushisa, ngoko ke kuyimfuneko ukukhetha izinto ezinamandla okwaneleyo kunye nokumelana nobushushu.

3. Iimeko zokusingqongileyo

Cinga ngeemeko zokusingqongileyo apho i-valve ikhona, njengomswakama, ityuwa yokutshiza, njl., kwaye ukhethe izinto ezifanelekileyo. 

4.Impahla yeValve yomzimba

Izixhobo zomzimba zevalvu yeiflange butterfly valvezibandakanya i-iron grey, i-ductile iron, i-cast steel, insimbi engenasici, njl. Phakathi kwazo, insimbi engenasici ineyona nto isebenzayo, kodwa ixabiso liphezulu kakhulu. Ukuba ikwimeko ephantsi yoxinzelelo, ukusebenza kwezinto zensimbi ze-ductile kunokuthelekiswa nezixhobo zetsimbi, kwaye iindleko zokusebenzisa i-ductile iron material iphantsi.

5.Impahla yokuhlala yeValve

Izinto zokuhlala zeIvalve yebhabhathane igiya yeentshulubeziquka irabha kunye ne-fluoroplastics. Izihlalo zevalve yerabha zingasetyenziswa kumajelo eendaba aneasidi ebuthathaka kunye nealkaline njengamanzi, umphunga, kunye neoyile, ngokutywinwa kokusebenza kakuhle; Izihlalo zevalvu ze-Fluoroplastic zisetyenziswa kumajelo eendaba ezonakalisa kakhulu.

6. Izinto zediski yebhabhathane

I-butterfly disc materials for manual butterfly valves ikakhulu ibandakanya i-ductile iron kunye nentsimbi engenasici. Ngamanye amaxesha, ukuze ulungelelanise iimeko zeendaba ezintsonkothileyo, kuyimfuneko ukusonga idiski yebhabhathane ngeglu okanye i-PTFE imathiriyeli.

7.Impahla ye-valve shaft

Uninzi lwazo lwenziwe ngezinto zensimbi ezingenasici, kwaye iimeko ezikhethekileyo zinokuthi zenziwe ngokweemfuno.

8.Drive imathiriyeli

Kukho iindlela ezimbini eziphambili zokusebenza ngesandla, umqheba kunye nesixhobo seentshulube. Izinto zokubamba ziquka intsimbi ekhatywayo, i-carbon steel, insimbi engenasici, i-aluminium alloy, njl. Izinto zentloko yegiya yeentshulube ubukhulu becala yintsimbi ephothiweyo.

Isishwankathelo, ukhetho lomgangatho wezinto eziphathekayomanual butterfly valvekufuneka ithathele ingqalelo ngokubanzi imiba enjengendawo yokusebenza, uxinzelelo lokusebenza kunye nobushushu, iimeko zokusingqongileyo, kunye nezixhobo zomzimba wevalvu, isihlalo sevalve, idiski yebhabhathane, kunye nevalve shaft. Ukukhethwa kwezinto ezichanekileyo kunokuqinisekisa ukusebenza okuqhelekileyo kunye nobomi benkonzoivalve yebhabhathane yamanzi.
