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

Incazelo:

I-valve yokukhulula umoya ehlanganisiwe enesivinini esikhulu ihlanganiswe nezingxenye ezimbili ze-valve yomoya ye-diaphragm enengcindezi ephezulu kanye ne-valve yokungena engcindezini ephansi kanye ne-valve yokukhipha umoya, inemisebenzi yokukhipha umoya kanye neyokungenisa umoya.
I-valve yokukhulula umoya we-diaphragm enomfutho ophezulu ikhipha ngokuzenzakalelayo inani elincane lomoya eliqongelelwe epayipini lapho ipayipi lingaphansi kwengcindezi.
Ivalvu yokungenisa umoya neyokukhipha umoya enengcindezi ephansi ayikwazi nje kuphela ukukhipha umoya osepayipini lapho ipayipi elingenalutho ligcwele amanzi, kodwa futhi nalapho ipayipi likhishwa noma kuvela ingcindezi engemihle, njengalapho ngaphansi kwesimo sokuhlukaniswa kwekholomu yamanzi, izovuleka ngokuzenzakalelayo futhi ingene epayipini ukuze kuqedwe ingcindezi engemihle.

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 ingcindezi yangaphakathi yesistimu iphansi kunengcindezi yomoya, isibonelo, lapho kuhlukaniswa ikholomu yamanzi, ivalvu yomoya izovulekela umoya ngokushesha ohlelweni ukuvimbela ukukhiqizwa kwe-vacuum ohlelweni. Ngesikhathi esifanayo, ukungena komoya ngesikhathi esifanele lapho uhlelo luthulula kungasheshisa isivinini sokuthulula. Ingxenye ephezulu yevalvu yokukhipha umoya ifakwe ipuleti elilwa nokucasula ukuze libushelelezi inqubo yokukhipha umoya, okungavimbela ukushintshashintsha kwengcindezi noma ezinye izinto ezibhubhisayo.
I-valve yokukhipha umoya enomfutho ophezulu ingakhipha umoya oqongelelwe ezindaweni eziphakeme ohlelweni ngesikhathi lapho uhlelo lungaphansi kwengcindezi ukuze kugwenywe lezi zenzakalo ezilandelayo ezingadala umonakalo ohlelweni: ukukhiya komoya noma ukuvaleka komoya.
Ukwandisa ukulahlekelwa ikhanda kohlelo kunciphisa izinga lokugeleza futhi ngisho nasezimweni ezimbi kakhulu kungaholela ekuphazamisekeni okuphelele kokulethwa koketshezi. Ukwandisa umonakalo we-cavitation, kusheshiswe ukugqwala kwezingxenye zensimbi, kwandise ukuguquguquka kwengcindezi ohlelweni, kwandise amaphutha emishini yokulinganisa, kanye nokuqhuma kwegesi. Thuthukisa ukusebenza kahle kokuhlinzekwa kwamanzi kokusebenza kwamapayipi.

Isimiso sokusebenza:

Inqubo yokusebenza kwevalvu yomoya ehlanganisiwe lapho ipayipi elingenalutho ligcwele amanzi:
1. Khipha umoya epayipini ukuze ukugcwaliswa kwamanzi kuqhubeke kahle.
2. Ngemva kokuba umoya osepayipini usuphelile, amanzi angena ku-valve yokungenisa kanye neyokukhipha umoya enomfutho ophansi, bese i-float iphakanyiswa yi-buoyancy ukuze kuvalwe ama-port okungenisa kanye nawokukhipha umoya.
3. Umoya okhishwa emanzini ngesikhathi senqubo yokulethwa kwamanzi uzoqoqwa endaweni ephezulu yesistimu, okungukuthi, ku-valve yomoya ukuze kuthathelwe indawo amanzi okuqala emzimbeni we-valve.
4. Lapho umoya uqongelela, izinga loketshezi ku-high-pressure micro automatic exhaust valve liyehla, kanti nebhola elintantayo nalo liyehla, lidonsa i-diaphragm ukuze livale, livule imbobo yokukhipha umoya, bese likhipha umoya.
5. Ngemva kokukhishwa komoya, amanzi angena futhi ku-valve yokukhipha umoya e-micro-automatic enomfutho ophezulu, antante ibhola elintantayo, bese evala imbobo yokukhipha umoya.
Uma uhlelo lusebenza, izinyathelo ezingenhla ezingu-3, ​​4, 5 zizoqhubeka nokujikeleza
Inqubo yokusebenza kwevalvu yomoya ehlanganisiwe lapho ingcindezi ohlelweni ingumfutho ophansi kanye nengcindezi yomoya (ekhiqiza ingcindezi engemihle):
1. Ibhola elintantayo levalvu yokungenisa umoya neyokukhipha umoya ephansi lizowa ngokushesha ukuze livule amachweba okungenisa umoya neyokukhipha umoya.
2. Umoya ungena ohlelweni usuka lapha ukuze uqede ukucindezela okungekuhle futhi uvikele uhlelo.
