Ii-valve yebholayaphuma ngawo-1950.Ngokuthuthuka okusheshayo kwesayensi nobuchwepheshe, ukuthuthukiswa okuqhubekayo kobuchwepheshe bokukhiqiza kanye nesakhiwo somkhiqizo, eminyakeni engama-40 nje kuphela, sekuthuthukiswe ngokushesha kwaba isigaba esikhulu se-valve.Emazweni asentshonalanga athuthukile, ukusetshenziswa kwama-valve ebhola kuyanda unyaka nonyaka.
Amavalvu amabhola asetshenziswa kakhulu ekuhluzeni uphethiloli, amapayipi ahamba amabanga amade, embonini yamakhemikhali, ekwenziweni kwamaphepha, kwezekhemisi, ekongiweni kwamanzi, kwamandla kagesi, ekuphathweni kukamasipala, ensimbi nakwezinye izimboni, futhi athatha isikhundla esibalulekile emnothweni kazwelonke.Inesenzo sokuzungeza amadigri angama-90, umzimba weqhude uyindilinga, enendilinga embobeni noma umzila odlula eksisi yayo.
I-valve yebhola isetshenziselwa kakhulu ukusika, ukusabalalisa kanye nokushintsha indlela yokuhamba kwe-medium epayipini.Idinga kuphela ukuzungezisa ama-degree angama-90 futhi i-torque encane ingavalwa ngokuqinile.I-valve yebhola ifaneleka kakhulu ukusetshenziswa njenge-switch kanye ne-valve yokuvala, i-valve yebhola emise okwe-V.Ngaphezu kokunaka imingcele yamapayipi, ama-valve kagesi kufanele aqaphele ngokukhethekile izimo zemvelo lapho asetshenziswa khona.Njengoba idivayisi kagesi ku-valve kagesi iyisisetshenziswa se-electromechanical, isimo sokusetshenziswa kwayo sithinteka kakhulu endaweni yokusetshenziswa kwayo.Ngaphansi kwezimo ezijwayelekile, ukunakwa okukhethekile kufanele kukhokhwe ekusebenziseni ama-valve ebhola kagesi nama-butterfly valves ezindaweni ezilandelayo.
Ukuhlukaniswa komsebenzi
1. I-valve ye-bypass: I-valve yebhola ngokuvamile ivulwa ngamanzi amile, ngakho i-valve ye-bypass isethelwe ukuba icindezelwe kuqala, okungukuthi, izinhlangothi zombili zigcwaliswa ngamanzi;
2. I-valve yomoya: lapho ugcwalisa amanzi, i-buoy izovala ngokuzenzakalelayo i-valve lapho umoya ukhishwa;lapho idonsa, i-buoy izokwehliswa ngokwayo lapho isetshenziselwa ukugcwalisa umoya;
3. I-valve yokunciphisa ukucindezeleka: lapho uvula futhi uvala i-valve, susa amanzi okucindezela phakathi kwe-valve nesembozo sokuvala ukuze ugweme ukugqoka ikhava yokuvala;
4. I-valve ye-sewage: khipha indle engxenyeni engezansi yegobolondo lebhola.
Ukuhlukaniswa kokudluliselwa
1. I-valve yebhola yomoya
2. I-valve yebhola kagesi
3. I-valve yebhola ye-hydraulic
4. I-valve yebhola ye-pneumatic hydraulic
5. I-valve yebhola ye-electro-hydraulic
6. I-valve yebhola ye-turbine drive
