Isimiso sokusebenza sembulunga yonkeivalvu:

Amanzi afakwa ngaphansi kwepayipi bese ekhishwa aye emlonyeni wepayipi, uma kucatshangwa ukuthi kukhona umugqa wamanzi onesivalo. Isivalo sepayipi lokukhipha sisebenza njengendlela yokuvala ivalvu yokumisa. Amanzi azokhishwa ngaphandle uma isivalo sepayipi siphakanyiswa ngesandla. Amanzi azoyeka ukubhukuda uma isivalo sepayipi simbozwe ngesandla sakho, okufana nomsebenzi wevalvu yokumisa.

Izici ze-globe valve:

Uma ifakiwe, ingena kancane futhi iphuma kakhulu, ukugeleza okuqondile, ukumelana okukhulu kokungqubuzana kwamanzi, ukukhiqizwa nokugcinwa okulula, isakhiwo esilula, ukunemba okuphezulu; isetshenziswa ikakhulukazi emanzini ashisayo nabandayo kanye namapayipi omusi acindezela kakhulu; ayisebenzi Izinyibilikisi ezinezinhlayiya ezincane kanye ne-viscosity ephezulu.

Isimiso sokusebenza kwe-ball valve:

Ubuso obuyindilinga endaweni yokungena kanye nokuphuma kufanele bubonakale ngokuphelele lapho ivalvu yebhola isijikelezile ngama-degrees angu-90. Ngaleso sikhathi, ivalvu ivaliwe ukuze kuvinjwe isinyibilikisi ekubhukudeni. Kufanele kube nezimbobo zebhola emnyango kanye nendawo yokuhlangana lapho ivalvu yebhola ijikeleza ngama-degrees angu-90, bese zivuleka futhi zibhukude ukuze kungabikho ukumelana nokugeleza kwamanzi.
Izici zama-valve ebhola:

Iivalvu yebholaKulula ukuyisebenzisa, iyashesha, futhi iyonga abasebenzi. I-valve yebhola ingasetshenziswa ngoketshezi olungahlanzekile kakhulu (oluqukethe izinhlayiya eziqinile) ngokumane uphendule isibambo se-valve ngama-degree angu-90. Lokhu kungenxa yokuthi uketshezi luthintwa yi-core eyindilinga ye-valve lapho ivulwa futhi ivalwa. Ukunyakaza kokusika.

Isimiso sokusebenza se-valve yesango:

Uhlobo oluvamile lwevalvu yivalvu yesango, ngezinye izikhathi eyaziwa ngokuthi ivalvu yesango. Umgomo wayo wokusebenza wokuvala nokuvala ukuthi izindawo zokuvala zepuleti yesango kanye nesihlalo sevalvu, ezihlangana ndawonye ukuvimba ukugeleza koketshezi oluphakathi nokuthuthukisa ukusebenza kokuvala kusetshenziswa isiphethu noma imodeli ebonakalayo yepuleti yesango, zibushelelezi kakhulu futhi zihambisana kahle. Umsebenzi oyinhloko wevalvu yesango ukuvimba ukudlula koketshezi ngepayipi.

Izici ze-valve yesango:

Ukusebenza kokuvala kuphakeme kunokwe-valve yomhlaba, ukumelana nokungqubuzana koketshezi kuphansi, ukuvulwa nokuvalwa kudinga umsebenzi owengeziwe, indawo yokuvala ayiboli kakhulu yi-solvent uma ivuliwe ngokugcwele, futhi ukusebenza kokuvala akuvinjelwanga yindlela yokugeleza kwezinto. Isikhathi sokuvula nokuvala side, usayizi mkhulu, futhi kudingeka indawo ethile. Lapho kuvulwa futhi kuvalwa, indawo yokuvala iyaguguleka futhi inqunywe kalula. Lezi zibhangqwana ezimbili zokuvala ziletha izinselele zokucubungula, ukulungisa, kanye nokukhiqiza.

Isifinyezo somehluko phakathi kwama-globe valve,amavalvu ebholanama-valve esango:

Nakuba ama-valve embulunga engasetshenziswa kokubili ekulawuleni ukugeleza kanye nokushintsha kokulawula uketshezi kanye nokunqamula, ama-valve ebhola kanye nama-valve esango ngokuvamile asetshenziselwa ukushintsha nokuvala kokulawula uketshezi futhi akuvamile ukusetshenziswa ekulawuleni ukugeleza. Kungcono ukusebenzisa i-valve yokumisa ngemuva kwemitha uma udinga ukushintsha izinga lokugeleza. Ama-valve esango asetshenziswa ekushintsheni kokulawula kanye nokusetshenziswa kokunqamula ngoba asebenza kahle ngokwezomnotho. Noma, kumapayipi kawoyela, umusi, namanzi anobubanzi obukhulu, anomfutho ophansi, sebenzisa ama-valve esango. Ukuqina kudinga ukusetshenziswa kwama-valve ebhola. Ama-valve ebhola angcono kunama-valve esango maqondana nokusebenza kokuphepha kanye nokuphila isikhathi eside, futhi angasetshenziswa ezindaweni ezinemigomo eqinile yokuvuza. Afaneleka futhi ukuvulwa nokuvalwa okusheshayo.
