Ivalve yeBhola eneZiqhekeza eziNtathu eziFlentshi: phucula ukhuseleko lombhobho wekhemikhali
Ukwakhiwa kunye neempawu zevalve yebhola eneziqwenga ezintathu
1. Ukwakha
Ivalve yebhola enamacala amathathu enamacala amathathu: umzimba wevalvu, ibhola kunye nesitulo sevalvu. Umzimba we-valve uxhunywe nge-flange, ekulula ukuyifaka nokugcina; ibhola ithatha uyilo lweziqwenga ezintathu kwaye inomsebenzi wokutywina kakuhle; isihlalo sevalvu sithatha izinto ezinganyangekiyo kwi-corrosion ezifana ne-PTFE, elungele ukuthuthwa kwemithombo yeendaba eyonakalisayo.
2. Iimpawu
(1) Ukusebenza kokutywina okugqwesileyo: Isihlalo sebhola kunye nevalve zenziwe ngezinto ezinganyangekiyo kwi-corrosion ezifana ne-PTFE, ezinomsebenzi wokutywina kwaye zinokuthintela ukuvuza okuphakathi.
(2) Ukusebenza okulula: Izixhobo ze-Manual, zombane okanye ze-pneumatic zisetyenziselwa ukufezekisa ukutshintsha ngokukhawuleza kunye nokunciphisa ubunzima bokusebenza.

(4) Ukuxhathisa okuqinileyo kwe-corrosion: Umzimba wevalve, ibhola kunye nesihlalo sevalve zenziwe ngezinto ezichasene ne-corrosion ezifana nensimbi engenasici kunye ne-carbon steel, efanelekileyo ekuthuthweni kwemithombo eyahlukeneyo yeendaba.
(5) Ubomi benkonzo ende: Yenziwe ngezinto ezikumgangatho ophezulu, inokumelana nokunxiba okuphezulu kunye nokumelana nefuthe kunye nobomi benkonzo ende.
3. Izinto eziluncedo kwiivalvu zebhola ezinamaqhekeza amathathu kwimibhobho yekhemikhali
3.1. Ukuphucula ukhuseleko lwemibhobho
(1) Thintela ukuvuza: Isihlalo sebhola kunye nevalve zenziwe ngezinto ezinomsebenzi obalaseleyo wokutywina, okuthintela ngokufanelekileyo ukuvuza okuphakathi kunye nokunciphisa umngcipheko weengozi.
(2) Nciphisa umngcipheko wokudubula: Ivalve yebhola inokumelana nomlilo kwaye inokusebenza ngokuqhelekileyo kwiindawo ezibuhlungu ezifana nobushushu obuphezulu kunye noxinzelelo oluphezulu, ukunciphisa umngcipheko wokudubula.
(3) Ukunqunyulwa ngokukhawuleza: Ivalve yebhola ithatha uyilo lweziqwenga ezintathu kunye nesantya sokutshintsha ngokukhawuleza. Iyakwazi ukunqumla ngokukhawuleza i-medium xa kwenzeka ingozi kwaye inciphise ilahleko yengozi.
3.2. Ukuphucula ukusebenza kakuhle kwemveliso
(1) Ukusebenza okulula: Ivalve yebhola kulula ukuyisebenzisa, igcina iindleko zabasebenzi, kwaye iphucula ukusebenza kakuhle kwemveliso.
(2) Ukugcinwa okulula: I-valve yebhola inesakhiwo esincinci, kulula ukuyichitha, kwaye kulula ukuyilungisa nokugcina.
(3) Ukuxhathisa okuqinileyo kwe-corrosion: I-valve yebhola ifanelekile kwiindidi ezahlukeneyo zeendaba ezitshabalalisayo kwaye ihlangabezana neemfuno ezahlukeneyo zothutho lweendaba kwinkqubo yokuvelisa imichiza.
4. Ukukhethwa kunye nokufakwa kwee-valve zebhola ezine-flanged ezintathu
4.1. Ukukhetha
(1) Ngokohlobo oluphakathi: khetha imathiriyeli efanelekileyo yokuqinisekisa ukuxhathisa kokubola kwevalve yebhola kwindawo ethile.
(2) Ngokweeparamitha zombhobho: misela i-diameter yegama, uxinzelelo lwegama kunye nezinye iiparamitha zevalve yebhola.
(3) Ngokwemeko yokusetyenziswa: qwalasela izinto ezifana nobushushu, uxinzelelo, ukufuma, njl., kwaye ukhethe uhlobo olufanelekileyo lwevalve yebhola.
4.2. Ukuhlohla
(1) Khangela ukuba ivalve yebhola kunye nezincedisi zayo zicocekile kusini na.
(2) Fakela ivalve yebhola kumbhobho ngokwemizobo yoyilo.
(3) Ngethuba lenkqubo yokufakela, nikela ingqalelo ekusebenzeni kokutywinwa kwe-flange ukuqinisekisa ukuba akukho kuvuza.
(4) Emva kokufakela, yenza uvavanyo loxinzelelo ukuze uqinisekise ukusebenza kokutywinwa kwevalve yebhola.
Ivalve yebhola ene-flanged emithathu ineenzuzo ezibalulekileyo ekuphuculeni ukhuseleko lwemibhobho kwishishini lemichiza. Ukusebenza kwayo okungaphezulu kokutywina, ukusebenza okulula, kunye nokuxhathisa okuqinileyo kwe-corrosion kwenza iivalvu zebhola zisetyenziswe ngokubanzi ngakumbi kwimibhobho yekhemikhali. Nangona kunjalo, kwizicelo zangempela, ingqwalasela kufuneka ihlawulwe kwakhona ekukhethweni nasekufakweni kwee-valve zebhola ukuqinisekisa ukusebenza kwazo okukhuselekileyo kunye nokuzinza kwinkqubo yokuvelisa imichiza. Ngengxoxo kweli nqaku, kunethemba lokuba kuya kuba luncedo ukuphucula ukhuseleko lwemibhobho kwishishini lemichiza.
