Ake sithi kukhona ipayipi lokuhambisa amanzi elinesembozo. Amanzi afakwa ngaphansi kwepayipi bese ekhishwa aye emlonyeni wepayipi. Isembozo sepayipi lokukhipha amanzi silingana nelungu lokuvala levalvu yokumisa. Uma uphakamisa isembozo sepayipi phezulu ngesandla sakho, amanzi azokhishwa. Mboza isivalo sepayipi ngesandla sakho, bese amanzi eyeka ukubhukuda, okulingana nomgomo wevalvu yokumisa.
Izici ze-globe valve:
Isakhiwo esilula, ukuqina okuphezulu, ukukhiqizwa nokugcinwa okulula, ukumelana okukhulu kokungqubuzana kwamanzi, kungalawula ukugeleza; uma kufakwa, kuphansi ngaphakathi nangaphandle okuphezulu, kuya ngqo; kusetshenziswa ngqo emanzini ashisayo nabandayo kanye namapayipi omusi acindezela kakhulu, akufaneleki ukususa izinhlayiya kanye nezinyibilikisi eziqinile kakhulu.
Isimiso sokusebenza kwe-ball valve:
Uma ivalvu yebhola ijikeleza ama-degrees angu-90, izindawo eziyindilinga kufanele zivele endaweni yokungena kanye nendawo yokukhipha amanzi, ngaleyo ndlela zivale ivalvu futhi zimise ukugeleza kwe-solvent. Uma ivalvu yebhola ijikeleza ama-degrees angu-90, ukuvulwa kwebhola kufanele kuvele kokubili endaweni yokungena kanye nendawo yokuhlangana, okulivumela ukuthi libhukude cishe ngaphandle kokumelana nokugeleza kwamanzi.
Izici ze-ball valve:
Ama-valve ebhola alula kakhulu, ayashesha futhi ayonga abasebenzi ukuwasebenzisa. Ngokuvamile, udinga kuphela ukuphendula isibambo se-valve ngama-degree angu-90. Ngaphezu kwalokho, ama-valve ebhola angasetshenziswa koketshezi olungahlanzekile kakhulu (oluqukethe izinhlayiya eziqinile) ngoba umongo we-valve yayo efana nebhola ushintsha uketshezi lapho uvula futhi uvala.
Isimiso sokusebenza kwe-valve yesango:
I-valve yesango, ebizwa nangokuthi i-valve yesango, iyi-valve esetshenziswa kakhulu. Umgomo wayo wokuvala ukuthi indawo yokuvala isango kanye nendawo yokuvala isihlalo se-valve kubushelelezi kakhulu, kuyisicaba futhi kuyahambisana, futhi kuhambisana ndawonye ukuvimba ukugeleza koketshezi oluphakathi, futhi kuthuthukise ukusebenza kokuvala ngosizo lwesiphethu noma imodeli ebonakalayo yepuleti yesango. umphumela wangempela. I-valve yesango idlala indima enkulu yokunqamula ukugeleza koketshezi epayipini.
Izici ze-valve yesango:
Ukusebenza kokuvala kungcono kunokwe-valve yokumisa, ukumelana nokungqubuzana koketshezi kuncane, ukuvulwa nokuvalwa akusebenzi kakhulu, indawo yokuvala ayigugi kakhulu yi-solvent uma ivuliwe ngokugcwele, futhi ayinqunyelwe yindlela yokugeleza kwezinto. Ineziqondiso ezimbili zokugeleza, ubude obuncane besakhiwo, kanye nezinkambu zokusetshenziswa ezibanzi. Usayizi uphakeme, kudingeka isikhala esithile ukuze kusebenze, futhi isikhathi sokuvula nokuvala side. Indawo yokuvala igugiswa futhi iklwejwe kalula ngesikhathi sokuvula nokuvala. Lezi zibhangqwana ezimbili zokuvala zibangela izinkinga ekukhiqizweni, ekucutshungulweni nasekugcinweni.
Isifinyezo somehluko phakathi kwama-globe valve, ama-ball valve nama-gate valve:
Ama-valve ebhola nama-valve esango avame ukusetshenziselwa ukulawula ukuvula/ukuvala nokunqamula uketshezi, kodwa awakwazi ukusetshenziselwa ukulungisa ukugeleza. Ngaphezu kokulawula ukuvula/ukuvala nokunqamula uketshezi, ama-valve okumisa angasetshenziswa futhi ukulungisa ukugeleza. Uma udinga ukulungisa izinga lokugeleza, kufaneleka kakhulu ukusebenzisa i-valve yokumisa ngemuva kwemitha. Ukuze kushintshwe ukulawula kanye nezinhlelo zokusika ukugeleza, ama-valve esango asetshenziswa ngenxa yezizathu zomnotho. Ama-valve esango ashibhile kakhulu. Noma sebenzisa ama-valve esango kumapayipi amakhulu, uwoyela ophansi, umusi, kanye namanzi. Uma ubheka ukuqina, kusetshenziswa ama-valve ebhola. Ama-valve ebhola angasetshenziswa ezimweni zokusebenza ezinezindinganiso eziphezulu zokuvuza, afanele ukuqala nokuvala ngokushesha, futhi asebenza kahle ngokuphepha futhi aphile isikhathi eside kunama-valve esango.
