Ngenxa yokungqubuzana okuphansi phakathi kwezindawo zokuvala ngesikhathi senqubo yokuvula nokuvala, ivalvu yokuvala ihlala isikhathi eside futhi inokuphakama okuncane kokuvula. Ayifanele kuphela ingcindezi ephakathi nephansi, kodwa futhi ifaneleka nakwezokuxhumana ezicindezelayo eziphezulu. Ngokuncika ekucindezelweni kwesiqu sevalvu, indawo yokuvala yediski kanye nendawo yokuvala yesihlalo sevalvu kunamathele eduze ukuvimbela indawo yokuvala ukuthi ingagelezi, okuyivalvu yokuvala ephoqelelwe. Ukuze kuvumelane nokusetshenziswa kwezikhathi ezahlukahlukene, kunezinhlobo ezine zamavalvu okuvala anemisebenzi ehlukene: ivalvu yokuvala i-plunger, ivalvu yokuvala i-direct flow, ivalvu yokuvala evamile kanye nevalvu yokuvala i-angle. Uyini umehluko phakathi kwawo?
1) Indawo yokungena kanye nendawo yokukhipha ivalvu yokumisa yohlobo lwe-angle ikwi-engeli yama-degrees angu-90. Ivalvu yokumisa yohlobo lwe-angle ngokuvamile ifakwa ekhoneni lepayipi futhi ingathatha indawo yejoyinti lepayipi ekhoneni.
Ku-valve yokuvala yohlobo lwe-angle, uketshezi ludinga ukushintsha indlela yalo kanye kuphela, ukuze ukwehla kwengcindezi nge-valve kube kuncane kunokwe-valve yokuvala evamile.
2) Izici zesakhiwo kanye namakhono okukhetha ivalvu yokumisa ukugeleza ngqo, ivalvu yokumisa ukugeleza ngqo, ivalvu yokumisa i-angle kanye nevalvu ye-plunger kuyivalvu yokumisa yohlobo lwe-Y. Nge-engeli engama-degrees angu-45, izinga lomonakalo esimweni sokugeleza lincane kunelevalvu yokuvala evamile, ngakho-ke ukulahlekelwa kwengcindezi ngevalvu nakho kuncane ngokufanayo. Kungashiwo futhi ukuthi cishe akukho ukulahlekelwa kwengcindezi, futhi futhi kuyindlela encane kakhulu yokulahlekelwa kwengcindezi kuwo wonke amavalvu okuvala.
3) I-valve ye-globe yohlobo lwe-Plunger: Lolu hlobo lwe-valve ye-globe luyinhlobonhlobo ye-globe valve evamile. Kule valve, i-disc kanye nesihlalo se-valve ngokuvamile kuklanywa ngokusekelwe kusimiso se-plunger. I-clack ye-valve ipholishwa ukuze i-plunger kanye nesiqu se-valve kuxhunywe, futhi ukuvalwa kufezwa ngamasongo amabili okuvala anwebekayo afakwe emahlombe ku-plunger. Amasongo amabili okuvala anwebekayo ahlukaniswa ngendandatho yesandla, kanti indandatho yokuvala ezungeze i-plunger icindezelwa ngokuqinile ngumthwalo osebenza ku-bonnet yi-bonnet nut. Indandatho yokuvala enwebekayo ingashintshwa futhi ingenziwa ngezinto ezahlukene. I-valve isetshenziswa kakhulu "ukuvula" noma "ukuvala", kodwa ifakwe uhlobo olukhethekile lwe-plunger noma ikhola ekhethekile. I-valve yesihlalo se-valve ephindwe kabili ibhalansi ye-plunger eqondile. I-plunger ingahamba phezulu naphansi emasongweni okuvala aphezulu naphansi kanye nesikhwama sokuqondisa. Isikhwama sokuqondisa sinikezwa imbobo yokulinganisela ingcindezi, futhi ingcindezi ephakathi ingangena emgodini ongezansi wesandla sokuqondisa ngembobo encane. Ukuvala kungafinyelelwa ngokubekwa kabili kokuvala kwe-plunger kanye nendandatho yokuvala kabili emzimbeni we-valve, futhi ukugeleza okukhulu kungadluliswa. Ngenxa yokuthi i-plunger imfushane, isivinini sokuvula nokuvala siphakeme kunese-valve evamile ye-plunger; ibhalansi yokucindezela iqonde ngqo nge-valve ye-plunger, I-plunger ayinalutho, futhi amakamelo aphezulu naphansi anezimbobo. Isiqu se-valve sixhunywe ne-sleeve yokuvala ephezulu kanye ne-nut ukuze kulinganiswe ingcindezi emakamelweni aphezulu naphansi e-plunger futhi kongiwe umzamo lapho kuvulwa futhi kuvalwa. Kodwa-ke, isiqu se-valve kumele sibe nokuvalwa okuphezulu kanye nokuvalwa kokupakisha, futhi isivinini sokuvula nokuvala sihamba kancane.
