Kwihlabathi elinzima lolawulo lolwelo, ngakumbi kumacandelo afana nobunjineli baselwandle, ukucubungula iikhemikhali, kunye nokuveliswa kombane, ukukhetha ivalvu efanelekileyo kunokuchaphazela kakhulu kungekuphela nje ukusebenza kakuhle kodwa kunye nokhuseleko kunye nokuthobela imiqathango yokusingqongileyo. Phakathi koluhlu olubanzi lweevalvu zoshishino ezikhoyo,ivalvu yeglobhukwaye iivalvu yeglobhu yesitywino esingaphantsiZimbini iindlela ezibalulekileyo ezisetyenziselwa ukuthomalalisa kunye nokulawula ukuhamba kwamanzi ngokuchanekileyo. Kodwa yintoni eyahlula ngokwenene? Kwaye kuba nini ukubaluleka kokukhetha enye kunenye?
Ukuqonda iValve yeGlobe eQhelekileyo
A ivalvu yeglobhuyivalvu yokuhamba ethe tye eyenzelwe ngokukodwa ukulawula ukuhamba. Ithiywe ngomzimba wayo omile okweglobhu, inediski ehamba ngokuthe nkqo kwisihlalo, ivumela amandla okujika athambileyo. Ngenxa yokuthembeka kwazo kunye nexabiso eliphakathi, iivalvu zeglobhu zisetyenziswa kakhulu kwiinkqubo zamanzi okusela amanzi ebhoyila, iisekethe zamanzi okupholisa, kunye neenkqubo zeoyile yepetroli.
Ezona mpawu
-
1. Yenzelwe ukuvala/ukuvula kunye nokuguqula ukuhamba kwamanzi
-
2. Ivaliwe kancinci
-
3.Ilungele ukusetyenziswa kwezinto eziquka ulwelo olungenakonakala
-
4. Kulula ukuyigcina kwaye ifumaneka ngokubanzi
Nangona kunjalo, kukho umngeni omnye oqhubekayo: ukuvuza kokupakisha isiqu ngokuhamba kwexesha. Kwiimeko zoxinzelelo oluphezulu okanye ubushushu obuphezulu, ukupakisha i-gland ejikeleze isiqu sevalvu kunokonakala, okuvumela imidiya ukuba iphume—okubeka umngcipheko wokhuseleko kunye nokusingqongileyo.
Yintoni Eyenza Iivalvu ZeGlobe ZeBellow Seal Zahluke?
A ivalvu yeglobhu yesitywino esingaphantsiithatha umgaqo ofanayo wokusebenza njengevalvu yehlabathi kodwa yazisa uphuculo olutshintsha umdlalo: aiimvuthuluka zesinyithiitywinwe nge-seal kwi-valve stem nakwi-bonnet. Olu yilo ludalaisitywina esingenamoya, isusa naluphi na ulwelo olunokwenzeka oluvuzayo esiqwini—into ebalulekileyoityhefu, i-radioactiveokanyeevuthayoizicelo.
Iingenelo eziphambili
-
1. Akukho ukuvuza kwesiqu—ilungele ulwelo oluyingozi olufana ne-ammonia, i-hydrogen, okanye ii-asidi
-
2.Ubomi obude bokusebenza obunokugcinwa okuncinci
-
3. Iyahambelana nemigangatho ye-fugie emission kunye ne-ISO 15848
-
4. Yehlisa ixesha lokungasebenzi kwaye yonyusa ukuthembeka kwenkqubo
Ivalvu yeGlobe yeBellow Seal VS iGlobe Valve
| Uphawu | Ivalvu yeGlobe | I-Bellow Seal Globe Valve |
|---|---|---|
| Uhlobo lweSitywino | Ukupakisha i-gland | Iimvuthuluka zentsimbi engenasici |
| Umngcipheko wokuvuza | Phakathi (ukwanda ngokuhamba kwexesha) | Iphantsi kakhulu |
| Ubuninzi boLondolozo | Phakathi ukuya phezulu | Iphantsi |
| Ukufaneleka kwesicelo | Iinkqubo zolwelo ngokubanzi | Iinkqubo ezibalulekileyo ezineendaba ezinobungozi |
| Ukuthobela iNdalo | Inomda | Iphezulu (ingangenisi ukukhutshwa kwegesi) |
| Ixabiso lokuqala | Ezantsi | Phezulu |
| Iindleko zoMjikelo woBomi | Iphezulu ngenxa yokugcinwa | Iphantsi ngenxa yokuqina kwayo |
Kutheni Ukhetho Lubalulekile KubantuIzicelo zaseLwandle
Kwiindawo zaselwandle, iivalvu zihlala zichatshazelwa ngamanzi anetyuwa, ukungcangcazela, kunye nobushushu obugqithisileyo. Nakuphi na ukuvuza—ingakumbi ekunikezelweni kwepetroli, amanzi okupholisa, okanye iinkqubo zokucima umlilo—kunokubangela imiphumo emibi kakhulu.
Iivalvu zeglobe eziqhelekileyo zisaxhaphakile kwiindawo ezingabalulekanga kangako, kodwa iivalvu zeglobe ze-bellow seal ziya kuba lolona khetho lukhethwayo ngokukhawuleza kwezi: Imigca yepetroli yegumbi lenjini, iinkqubo zamanzi zeBallast, ukusetyenziswa komphunga obushushu obuphezulu kunye nemibhobho yamakhemikhali eCargo.
