Amavalvu ahlukahlukene “esihlahleni sikaKhisimusi” ahlanganisa ndawonye isikhungo sokulawula ukuphepha komthombo wamafutha. Asebenza ngokubambisana ngokwemisebenzi efana nokulawula okuyinhloko, ukukhiqizwa kwansuku zonke kanye nokugcinwa kwezimo eziphuthumayo.
Amavalvu Okulawula Ayinhloko (Umgogodla Wokuphepha)
Ngokuvamile i-valve yesango eqhutshwa ngamanzi etholakala phezulu. Umsebenzi wayo ukuvala ngokushesha esimweni esiphuthumayo ukuze kunqunywe ukuxhumana phakathi kwekhanda lomthombo kanye nenqubo engenhla, kuvinjelwe ingozi ukuthi ikhule. Isebenza njengesithiyo esiyinhloko sokuphepha.
Ngokuvamile i-valve yesango elenziwa ngesandla etholakala ngaphansi kwe-valve eyinhloko ephezulu. Umsebenzi wayo ukusebenza njengesithiyo sesibili sokuphepha nokunikeza ukuhlukanisa lapho i-valve eyinhloko ephezulu idinga ukulungiswa. Ayivuleki ngokuphelele ngesikhathi sokukhiqiza okuvamile.
Amavalvu Okukhiqiza (Ukusebenza Kwansuku Zonke)
Ngokuvamile ivalvu ezenzakalelayo eqhutshwa ngamanzi exhunywe epayipini eliyinhloko lokukhipha uwoyela. Umsebenzi wayo ukuvala noma ukulawula isiteshi esikhulu sokukhipha uwoyela negesi emthonjeni ezimweni eziphuthumayo noma ngesikhathi sokusebenza kwansuku zonke.
Akuyona ivalvu elula yokuvula, kodwa iyithuluzi elibalulekile lokulawula ukugeleza kwamanzi. Ngokushintsha ama-choke anobubanzi obuhlukene bangaphakathi, izinga lokukhiqizwa komthombo kanye nokucindezela kwekhanda lomthombo kungalawulwa ngokunembile.
Amavalvu Asizayo (Ukulungiswa Nokujova)
Itholakala phezulu, isetshenziswa ngesandla. Ivulwa uma kudingeka intambo yocingo, ikhebula noma eminye imisebenzi yokudonsa phansi noma ukulinganisa ingcindezi, futhi ivalwa ngezinye izikhathi.
Isetshenziswa ngesandla. Isetshenziselwa ukufaka uketshezi olubulala umthombo, izinto ezivimbela amakhemikhali (ezilwa nokugqwala, ezilwa nokubanda), kanye nezinye izinto eziwuketshezi emthonjeni.
Ngesikhathi sokukhiqiza okuvamile, i-valve ephezulu, i-valve ephansi kanye ne-valve yephiko lokukhiqiza kuyavuleka, kanti uwoyela negesi kukhiqizwa ngemuva kokulawulwa yi-choke. I-valve yokuhlanza i-wax kanye ne-valve yephiko elibulala kahle ngokuvamile kuvalwe. Uma kwenzeka isimo esiphuthumayo, uhlelo luzovala ngokuzenzakalelayo ngokulandelana: i-choke → i-valve yephiko lokukhiqiza → i-valve ephezulu → i-valve ephansi. Lolu chungechunge lungahlukanisa umthombo wamafutha ngokushesha nangokuphephile.
Amavalvu “esihlahla sikaKhisimusi” angaphansi kwamanzi asetshenziswa ekusetshenzisweni kolwandle olujulile anezidingo eziqinile ngaphezu kwemisebenzi engenhla:
