I-Gate Valve vs i-Globe Valve: Umahluko oPhambili, ii-Applications, kunye nokuChongwa
Iipayipi zemizi-mveliso zixhomekeke kulawulo oluchanekileyo lokuhamba kwamanzi, nto leyo eyenza ukukhetha iivalvu kube yinto ebalulekileyo. Iindidi ezimbini ezisisiseko—iivalvu zesango kunye neevalvu zeglobe—zisebenza ngeenjongo ezahlukeneyo nangona zifana ngokubonakalayo. Esi sikhokelo sicacisa umahluko wazo, ukusetyenziswa kwazo, kunye neendlela zokuchonga.
Yintoni iValve yeSango
Ivalvu yesangoilawula ukuhamba kwamanzi ngokuphakamisa okanye ukwehlisa “isango” eliyingxande okanye elimile okwesikwere ngesiqu esinomgca. Iimpawu eziphambili:
Umsebenzi: Ivuliwe/ivaliwe ngokupheleleyo kuphela; ayifanelekanga ukuqhoboshelwa.
Indlela Yokuhamba: Uyilo oluthe ngqo lunciphisa ukwehla koxinzelelo.
Ukutywina: Vala ngokuqinileyo xa uvale ngokupheleleyo, kwaye umngcipheko wokuvuza uphantsi.
Izicelo: Iikhemikhali zepetrochemicals, unikezelo lwamanzi, imibhobho emikhulu apho kufuneka khona ukumelana nokuhamba kwamanzi okuncinci.
Umzekelo:Kwiinkqubo zamanzi zikamasipala, iivalvu zesango ziyawahlula amacandelo ngexesha lokulungiswa ngenxa yokumelana kwazo nokungaphumi kwamanzi xa zivuliwe.
Yintoni iGlobe Valve
Ivalvu yehlabathi(okanye ivalvu yokumisa) ilawula ukuhamba kwamanzi isebenzisa idiski okanye iplagi ecinezela ngokuthe nkqo esihlalweni. Iimpawu eziphambili:
Umsebenzi: Yenzelwe ukuqhobosha nokuqhuba rhoqo.
Indlela Yokuhamba: Isekethe enomfanekiso-S yonyusa ukumelana kodwa ivumela ulawulo oluchanekileyo.
Ukutywina: Indlela yokutywina ngenkani ifuna amandla aphezulu okuvala.
IziceloIibhoyila, iiHVAC, iinkqubo zomphunga—nayiphi na imeko efuna ukulungiswa kokuhamba kwamanzi.
Umzekelo: Iivalvu zeglobe zilawula ukuhamba komphunga kwizityalo zamandla, zivumela abaqhubi ukuba balungise uxinzelelo.
Umahluko ophambili: I-Gate Valve vs I-Globe Valve
| Umbono | Ivalvu yeSango | Ivalvu yeGlobe |
|---|---|---|
| Ulwakhiwo | Indlela ethe tye yokuhamba; isango liphakama ngokuthe nkqo | Indlela yokuhamba kwe-S; idiski ihamba ngokuthe nkqo kwisihlalo |
| Umsebenzi | Ivuliwe/icinyiwe kuphela; akukho kuqhoboshelwa | Ukuqhobosha nokuvula/ukucima |
| Ukumelana nokuhamba kwamanzi | Iphantsi kakhulu (xa ivuliwe ngokupheleleyo) | Phezulu (ngenxa yotshintsho lwendlela) |
| Ukuphakama kwesiqu | Mde (uyilo lwesiqu esinyukayo) | Incinci |
| Ufakelo | Ukuhamba kweendlela ezimbini | Isikhokelo (utolo lubonisa indlela yokuhamba) |
Indlela Yokuchonga Iivalvu Zesango kunye neeValvu Zeglobe
1. Uhlolo olubonakalayo:
Ivalvu yeSango: Umzimba omde (ingakumbi iintlobo zesiqu esinyukayo); ivili lesandla liyaphakanyiswa xa ivalvu ivuleka.
Ivalvu yeGlobe: Umzimba ongqukuva; ubude besiqu bufutshane.
2. Isikhokelo sokuhamba komoya:
Iivalvu zesango zivumela ukuhamba kweendlela ezimbini.
Iivalvu zeglobe zineentolo ezibhekise kwicala elithe ngqo emzimbeni.
3. Ukusebenza kwevili lesandla:
Iivalvu zesango zifuna ukujikeleza okuphindaphindiweyo ukuze zivuleke/zivalwe.
Iivalvu zeglobe zivula/zivaleka ngokukhawuleza (ukuhamba okufutshane kwesikhondo).
Ixesha lokusebenzisa iValve nganye
Khetha iiValvu zeSango:
1. Ukwahlulwa kokuhamba kwamanzi ngokupheleleyo kwimibhobho yamanzi/yeoyile.
2. Iinkqubo zokunciphisa uxinzelelo oluphantsi (umz., uthutho oluhamba umgama omde).
3. Ukusebenza okungacwangciswanga rhoqo (umz., ukuvalwa kwenkonzo ngexesha likaxakeka).
Khetha iiGlobe Valve ze:
1. Ulawulo lokuhamba kwamanzi (umz., iinkqubo zokupholisa).
2. Ukusebenza rhoqo (umz., ukulungiswa kwemihla ngemihla).
3. Ukusetyenziswa komphunga/igesi enoxinzelelo oluphezulu.
Kutheni Ukukhetha Iivalvu Kubalulekile
Ukukhetha ivalvu engalunganga kubeka emngciphekweni ukungasebenzi kakuhle kwenkqubo okanye ukungaphumeleli kwayo. Iivalvu zesango zikhupha amanzi amaninzi kwiindawo ezivulekileyo kodwa zivuza kancinci ukuba zivaliwe kancinci. Iivalvu zeglobe zibonelela ngolawulo kodwa zonyusa iindleko zamandla ngenxa yokuxhathisa. Soloko ulinganisa uhlobo lwevalvu neemfuno zokusebenza—ukuqinisekisa ukhuseleko, ixesha elide, kunye nokusebenza okuphezulu.
Ingcebiso yobungcali:Kwiinkqubo zoxinzelelo oluphezulu, dibanisa iivalvu zesango (ukwahlulwa okuphambili) kunye neevalvu zeglobe (ulawulo oluchanekileyo) ukuze ufumane iziphumo ezilungileyo.
