Zeziphi izinto ezifanele ziqwalaselwe xa ukhetha isango?

I-Palve yesangoUkukhetha: Ukuqwalaselwa okuninzi okuhlukeneyo ukuqinisekisa ukuziqhelanisa

Njengesixhobo esiphambili kulawulo lwamanzi, i-valve yesango kufuneka ikhethwe ngokusekwe kwizinto ezininzi ukuqinisekisa ukusebenza ngokuzinzileyo nokusebenza ngokufanelekileyo phantsi kweemeko ezithile zomsebenzi.

Okokuqala, iimpawu zephakathi sisiseko sokukhethaI-valves yesango. Imithombo yeendaba ezahlukileyo ineemfuno ezahlukeneyo zezinto zamasango. Umzekelo, xa uhambisa amajelo eendaba aphezulu kakhulu njenge-Sulfuric Acid, njl njl. Udonga lwangaphakathi lwe-valve ifakwe i-fluoroplastics, enokuthi ixhathise ukususwa kwaye kwandise ubomi benkonzo ye-valve yesango. Ukuba i-Pivepment inamasuntswana aqinileyo, indawo yokutywina kunye nejelo lokuhamba kwe-valve yesango kufuneka inxibe ukungcungcuthekiswa kokuthintela ukuvuza kunye nokuqinisekisa ukusebenza kwesonka sesango.

Okwesibini, uxinzelelo lokusebenza kunye nobushushu bubalulekile ekukhetheni iivalves zesango. Phantsi kweemeko zoxinzelelo oluphezulu, iivalves zesango kufuneka zibe namandla awoneleyo kunye nokuqina okuqinileyo kuxinzelelo lwe-medium ngaphandle kwengxaki okanye ukugqabhuka. Umzekelo, iivalves zesango zentsimbi zihlala zisetyenziswa kwimibhobho yoxinzelelo oluphezulu kumzi-mveliso wePetrochemical. Zenziwe ngeenkqubo zokwenzakala, zinesakhiwo esithile, kwaye sinokumelana noxinzelelo oluphezulu. Ngokweqondo lobushushu, imithombo yeendaba ephakamileyo inokubangela ukwanda kwexabiso le-valves, echaphazela ukutywinwa kunye nokusebenza kokusebenza, ngelixa amaqondo okusasaza asezantsi anokwenza ukuba izinto zenziwe zibrittletle. Ke, kufanelekileI-Palve yesangoIzixhobo kunye nezakhiwo kufuneka zikhethwe ngokoluhlu lwamaqondo obushushu. Umzekelo, i-valve yesango eliphezulu lobushushu basebenzisa izixhobo ezizodwa zesabelo, ngelixa i-valve yesango lobushushu ephantsi ihlasela iphantsi kweqondo lobushushu.

Ngaphaya koko, iimeko zokusebenza kunye neemfuno azinakutyeshelwa. Izihlandlo ezifuna ukuvulwa rhoqo nokuvala, ukuvulwa nokuvulwa kwamasango kufuneka zibe mncinci, kwaye utyando kufuneka kube lula. I-valve yombane okanye i-pneumatic yesango inokukhethwa ukufezekisa ulawulo lwe-Automation kunye nokuphucula ukusebenza kakuhle komsebenzi. Ukuba umsebenzi ophezulu wokutywina uyafuneka kwimibhobho equlathe imithombo yeendaba enokufudukayo kunye negesi, irhasi yendalo, enamasango etywina i-valve ephindwe kabini kwaye inokuthintela ngokufanelekileyo ukuvuza.

Ukongeza, izinto ezinje ngesakhiwo sokufaka kunye neendlela zonxibelelwano ze-valves yesango kufuneka ziqwalaselwe. Ukukhethwa kwengqondo kwamasango kunokuqinisekisa ukusebenza kwabo ngokuthethwa kwenkqubo, ukuqinisekisa ukhuseleko lwemveliso kunye nozinzo.
