Isimiso sokusebenza somhlabai-valve:

Amanzi ajovwa kusukela phansi epayipini bese ededelwa aye ngasemlonyeni wepayipi, kucatshangwa ukuthi kukhona umugqa wokuphakela amanzi onekepisi. Isembozo sepayipi eliphumayo lisebenza njengendlela yokuvala yevalvu yokumisa. Amanzi azokhishelwa ngaphandle uma isivalo sepayipi siphakanyiswa mathupha. Amanzi azoyeka ukubhukuda uma isivalo seshubhu simbozwe ngesandla sakho, okufana nomsebenzi wevalvu yokumisa.

Izici ze-globe valve:

Lapho ifakiwe, iphansi futhi iphuma phezulu, ukugeleza okuqondisayo, ukumelana nokungqubuzana okukhulu kwamanzi, ukukhiqizwa nokugcinwa okulula, isakhiwo esilula, ukunemba okuphezulu; esetshenziswa ngokukhethekile ekunikezeni amanzi ashisayo nabandayo kanye namapayipi esitimu anomfutho ophezulu; akusebenzi Izincibilikisi ezinezinhlayiyana kanye ne-viscosity ephezulu.

Umgomo wokusebenza kwe-Ball valve:

Indawo eyindilinga endaweni yokungena nokuphumayo kufanele ibonakale ngokuphelele lapho i-valve yebhola isizungezisa amadigri angama-90. Ngaleso sikhathi, i-valve ivaliwe ukuze i-solvent ingakwazi ukubhukuda. Kufanele kube nezimbobo zamabhola emnyango nasezimpambanweni zomgwaqo lapho ivalve yebhola izungeza amadigri angama-90, futhi kufanele ivuleke futhi ibhukude ukuze kungabikho ukumelana nokugeleza.
Izici zama-valve ebhola:

Ii-valve yebholakulula ukuyisebenzisa, iyashesha, futhi yonga umsebenzi. I-valve yebhola ingasetshenziswa noketshezi olungahlanzekile kakhulu (oluqukethe izinhlayiya eziqinile) ngokumane uphendule isibambo sevalvu ngamadigri angu-90. Lokhu kungenxa yokuthi uketshezi luthintwa umgogodla oyisiyingi we-valve lapho ivulwa futhi ivalwa. ukunyakaza kokusika.

Isimiso sokusebenza se-valve yesango:

Uhlobo oluvamile lwe-valve yi-valve yesango, ngezinye izikhathi eyaziwa ngokuthi i-valve yesango. Umgomo wayo wokuvala nokuvala owokuthi izindawo zokuvala zepuleti lesango kanye nesihlalo se-valve, ezihlangana ndawonye ukuze zivimbele ukugeleza koketshezi oluphakathi nendawo futhi zithuthukise ukusebenza kokuvala kusetshenziswa intwasahlobo noma imodeli ebonakalayo yepuleti lesango, zidlulele. bushelelezi futhi buhambisana. umphumela wangempela. Umsebenzi oyinhloko we-valve yesango ukumisa ukudlula koketshezi epayipini.

Izici ze-valve yesango:

Ukusebenza kokuvala kuphakeme kunokwe-valve yembulunga, ukumelana nokungqubuzana koketshezi kuphansi, ukuvula nokuvala kudinga umsebenzi owengeziwe, indawo yokuvala yonakaliswa kancane yi-solvent uma ivuleke ngokugcwele, futhi ukusebenza kokuvala akukhawulelwe isiqondiso sokugeleza kwempahla. Isikhathi sokuvula nokuvala side, ubukhulu bukhulu, futhi inani elithile legumbi liyadingeka. Lapho uvula futhi uvala, indawo yokuvala iguguleka kalula futhi isikwe. Amapheya amabili okuvalwa aletha izinselele ekucubunguleni, ekunakekeleni nasekukhiqizeni.

Isifinyezo somehluko phakathi kwama-valve embulunga,ama-valve ebholanama-valve esango:

Nakuba ama-valve embulunga angasetshenziselwa kokubili ukulawulwa kokugeleza kanye nokushintshwa kokulawula uketshezi kanye nokunqanyulwa, ama-valve ebhola nama-valve esango ngokuvamile asetshenziselwa ukushintshwa kokulawula uketshezi kanye nokunqanyulwa futhi kuyaqabukela ekulawuleni ukugeleza. Kungcono ukusebenzisa i-valve yokumisa ngemuva kwemitha uma udinga ukuguqula izinga lokugeleza. Ama-valve esango asetshenziswa ekushintsheni kokulawula nasekunqamuleni izinhlelo zokusebenza ngenxa yokuthi ayasebenza ngokwezomnotho. Noma, ngobubanzi obukhulu, uwoyela onengcindezi ephansi, isitimu, namapayipi amanzi, sebenzisa amavalvu esango. Ukuqina kudinga ukusetshenziswa kwama-valve ebhola. Amavalvu ebhola aphakeme kunamavalvu esango ngokusebenza kokuphepha nempilo yokuphila, futhi angasetshenziswa ezindaweni ezinemibandela eqinile yokuvuza. Zibuye zifanele ukuvulwa nokuvala ngokushesha.
