I-Cast Iron Ductile Iron Air Relief Valve Flange End Water Air & Vacuum Release Valves

Incazelo:

Ivalvu yokukhishwa komoya eyinhlanganisela enesivinini esiphezulu ihlanganiswe nezingxenye ezimbili ze-high-pressure diaphragm air valve kanye ne-low pressure inlet kanye ne-exhaust valve, inayo kokubili imisebenzi yokukhipha kanye neyokudonsa.
Ivalvu ekhipha umoya we-diaphragm enomfutho ophezulu ikhiphela ngokuzenzakalelayo inani elincane lomoya eliqoqwe epayipini lapho ipayipi lingaphansi kwengcindezi.
I-valve yokungenisa ingcindezi ephansi kanye ne-exhaust valve ayikwazi nje ukukhipha umoya epayipini lapho ipayipi elingenalutho ligcwele amanzi, kodwa futhi lapho ipayipi ichitheka noma ingcindezi engalungile iyenzeka, njengangaphansi kwesimo sokuhlukaniswa kwekholomu yamanzi, izovuleka ngokuzenzakalelayo futhi ifake ipayipi ukuze iqede ukucindezela okubi.

Izidingo zokusebenza:

I-valve yokukhipha umoya enengcindezi ephansi (uhlobo lwe-float + float) imbobo enkulu yokukhipha umoya iqinisekisa ukuthi umoya ungena futhi uphume ngesivinini esikhulu sokugeleza komoya ophuma ngesivinini esikhulu, ngisho nokugeleza komoya okushesha kakhulu okuxutshwe nenkungu yamanzi, ngeke kuvale imbobo yokukhipha umoya kusenesikhathi. Imbobo yomoya izovalwa kuphela ngemva kokuba umoya usukhishwe ngokuphelele.
Nganoma yisiphi isikhathi, inqobo nje uma ukucindezela kwangaphakathi kwesistimu kuphansi kunokucindezela komkhathi, isibonelo, lapho ukuhlukaniswa kwekholomu yamanzi kwenzeka, i-valve yomoya izovula ngokushesha emoyeni ohlelweni ukuvimbela ukukhiqizwa kwe-vacuum ohlelweni. Ngesikhathi esifanayo, ukungena komoya okufika ngesikhathi lapho uhlelo luthulula kungasheshisa isivinini sokuthulula. Ingaphezulu le-valve yokukhipha insimbi ifakwe ipuleti elilwa nokucasula ukuze bushelelezi inqubo yokukhipha umoya, engavimbela ukushintshashintsha kwengcindezi noma ezinye izinto ezilimazayo.
I-valve yokukhipha i-high-pressure trace exhaust ingakhipha umoya oqoqwe ezindaweni eziphakeme ohlelweni ngesikhathi lapho uhlelo lungaphansi kwengcindezi ukuze kugwenywe lezi zenzakalo ezilandelayo ezingase zidale ukulimala ohlelweni: ukukhiya komoya noma ukuvinjelwa komoya.
Ukwandisa ukulahlekelwa kwekhanda kwesistimu kunciphisa izinga lokugeleza futhi ngisho nasezimweni ezimbi kakhulu kungaholela ekuphazamisekeni okuphelele kokulethwa kwamanzi. Qinisa ukulimala kwe-cavitation, usheshise ukugqwala kwezingxenye zensimbi, ukhuphule ukuguquguquka kwengcindezi ohlelweni, ukhuphule amaphutha emishini yokukala, nokuqhuma kwegesi. Ukuthuthukisa ukusebenza kahle kokuphakelwa kwamanzi ekusebenzeni kwamapayipi.

Umgomo wokusebenza:

Inqubo yokusebenza ye-valve yomoya ehlanganisiwe lapho ipayipi elingenalutho ligcwele amanzi:
1. Khipha umoya epayipini ukwenza ukugcwaliswa kwamanzi kuqhubeke kahle.
2. Ngemva kokuba umoya osepayipini usuthululiwe, amanzi angena kuvalvu yokukhipha ingcindezi ephansi, futhi iflothi iphakanyiswa yi-buoyancy ukuze kuvalwe izimbobo zokungena nokukhipha umoya.
3. Umoya okhishwe emanzini ngesikhathi sokulethwa kwamanzi uzoqoqwa endaweni ephakeme yesistimu, okungukuthi, ku-valve yomoya ukuze kuthathelwe indawo amanzi okuqala emzimbeni we-valve.
4. Ngokunqwabelana komoya, izinga loketshezi kuvalvu yokukhipha umoya othomathikhi yokucindezela okuphezulu kakhulu liyehla, nebhola le-float nalo liyehla, lidonse i-diaphragm ukuze livaleke, livule imbobo yokukhipha umoya, futhi likhiphe umoya.
5. Ngemva kokukhululwa komoya, amanzi angena kuvalvu yokukhipha i-micro-automatic enengcindezi ephezulu futhi, antante ibhola elintantayo, futhi avale imbobo yokukhipha umoya.
Uma uhlelo lusebenza, izinyathelo ezingenhla ezi-3, 4, 5 zizoqhubeka nokujikeleza
Inqubo yokusebenza ye-valve yomoya ehlanganisiwe lapho ingcindezi ohlelweni ingumfutho ophansi kanye nomfutho womkhathi (okhiqiza umfutho ongemuhle):
1. Ibhola elintantayo le-low pressure intake kanye ne-valve yokukhipha umoya izokwehla ngokushesha ukuze ivule izimbobo zokungenisa nokukhipha umoya.
2. Umoya ungena ohlelweni kusukela kuleli phuzu ukuze uqede ingcindezi engalungile futhi uvikele uhlelo.
