Kwihlabathi lolawulo lolwelo lwemizi-mveliso, ukusebenza kakuhle, ukuthembeka, kunye nokhuseleko zezona zinto zibalulekileyo. Phakathi kwezixhobo ezahlukeneyo ezenzelwe le njongo,ivalvu yebhola yokujika ikotaIbonakala njengesiseko seenkqubo zanamhlanje zokufaka imibhobho. Esi sikhokelo sibanzi siza kujonga nzulu into eyenza ezi valve zisebenze kangaka, sihlolisise ukusebenza kwazo, iintlobo zazo, kunye neendlela ezibalulekileyo zokukhetha, sikunike amandla okwenza ukhetho olufanelekileyo kwiimfuno zakho ezithile.
Ukuqonda Ulawulo Lolwelo kunye Nokubaluleka Kwalo
Ulawulo lolwelo yindlela yokulawula isantya sokuhamba, uxinzelelo, kunye necala lolwelo kunye neegesi ngaphakathi kwenkqubo. Ulawulo oluchanekileyo lubalulekile kumashishini amaninzi—ukusuka kwioyile kunye negesi ukuya kumayeza kunye nokulungiswa kokutya. Luqinisekisa ukhuseleko lokusebenza, ukusebenza kakuhle kwenkqubo, umgangatho wemveliso, kunye nokukhuselwa kwendalo. Ukukhethwa kwevalvu, icandelo eliphambili kule loop yolawulo, kuchaphazela ngokuthe ngqo ukusebenza kwenkqubo yonke kunye nobude bayo.
Zeziphi iiValve eziqukiweyo kwiiValve zeQuarter Turn?
Njengoko igama lisitsho,iivalvu zokujika zekotaifuna ukujika kwe-actuator ngama-90 degrees kuphela ukuze isuke ekuvulekeni ngokupheleleyo iye ekuvalekeni ngokupheleleyo. Olu sapho lweevalvu luyaziwa ngokulula kwayo kunye nesantya sokusebenza. Iindidi eziphambili ziquka:
Iivalvu zeBhola
Uhlobo oluqhelekileyo, olusebenzisa ibhola ejikelezayo enebhore ukulawula ukuhamba. Zinika amandla okuvala agqwesileyo kwaye ziyakwazi ukumelana noxinzelelo kunye namaqondo obushushu ahlukeneyo.
Iivalvu zebhabhathane
Ezi valve zinediski ejikeleza kwi-axis esembindini, zincinci, zikhaphukhaphu, kwaye zingabizi kakhulu kwiindlela ezinkulu nezinoxinzelelo oluphantsi.
Iivalvu zePlug
Zisebenza njengeevalvu zebhola kodwa zisebenzisa iplagi esisilinda okanye esikhonkwane endaweni yebhola. Ziqinile kwaye zilungele ukuphatha i-slurry kunye ne-abrasive media.
Indlela iiValve zeBhola zeQuarter Turn ezisebenza ngayo
Ukusebenza kweivalvu yebhola yokujika ikotailula kakhulu. Umbindi wevalvu yibhola engqukuva enomngxuma (imbobo) embindini wayo. Le bhola ihleli ngaphakathi komzimba wevalvu kwaye iqhagamshelwe kwisiphatho sangaphandle okanye kwi-actuator ngesiqu.
* Indawo evulekileyo:Xa isiphatho sijikwe ngama-90 degrees, ibhola iyajikeleza ukuze imbobo ihambelane nombhobho, nto leyo evumela ulwelo ukuba ludlule ngaphandle kokumelana kakhulu.
* Indawo eValiweyo:Ukubuyisela isibambo umva ngama-90 degrees kubeka imbobo ngokuthe nkqo kwindlela ehamba ngayo, kuyivala ngokupheleleyo. Ibhola ivalwe kwizihlalo eziguquguqukayo (ezidla ngokwenziwa nge-PTFE okanye ezinye iipolymers), ukuqinisekisa ukuvalwa okuqinileyo, okungenamaqamza.
Le ndlela ilula yokuvula/ukucima iyenza isebenze ngokukhawuleza kakhulu kwaye ithembeke.
Iintlobo zeeValve zeBall Turn zeKota
Iivalvu zebhola ezijika ikotainokwahlulwahlulwa ngokusekelwe kwizinto, uhlobo lonxibelelwano, kunye nolwakhiwo lomzimba ukuze ilungele yonke into enokucingelwa.
Uhlulo ngokwezinto eziphathekayo
Yenziwe ngentsimbi eshayinayo
