Umehluko Phakathi Kwevalvu Yokuvala Okusheshayo Nevalvu Ezivala Ngokwayo

Ezinhlelweni zasolwandle nezezimboni, ukuphepha nokusebenza kahle kuncike ekutheni ivalvu ingasabela ngokushesha kangakanani esimweni esiphuthumayo. Izinhlobo ezimbili zamavalvu ezivame ukudidaniswa yilezi:i-valve yokuvala esheshayokanyeivalvu ezivala yonaNakuba amagama azo ezwakala efana, izakhiwo zawo, izimiso zokusebenza, kanye nezinhlelo zokusebenza ziyahlukahluka. Ukuqonda umehluko kusiza ukuqinisekisa ukuthi i-valve efanele isetshenziswa ohlelweni olufanele.

Iyini i-Valve Yokuvala Okusheshayo

I-valve yokuvala okusheshayo yenzelwe ukuvala ukugeleza koketshezi noma igesi ngokushesha uma kwenzeka isimo esiphuthumayo. Ivame ukutholakala emapayipini kawoyela wasolwandle, ezinhlelweni zokugcoba, kanye namagumbi enjini lapho impendulo esheshayo ibalulekile ukuvimbela umlilo noma ukuvuza.

Ivalvu isebenza ngomshini wokulawula okude—ngokuvamile ucingo noma i-lever exhunywe esibambweni ngaphandle kwegumbi lenjini. Uma idonswa, ikhulula ivalvu, ivumele ukuthi ivaleke ngokushesha ngamandla esiphethu. Lesi sici sivumela amalungu eqembu ukuthi ahlukanise uhlelo lukaphethiloli ngokushesha ngaphandle kokungena endaweni eyingozi.

Izici Eziyinhloko Zama-Valve Okuvala Okusheshayo

• ①Isebenza kude ukuze kuphephe ngesikhathi somlilo noma izimo zokuvuza.

• ②Ivala ngokushesha ukuze inqamule ukutholakala koketshezi.

• ③Ngokuvamile ilayishwa ngesiphethu noma isekelwe umoya.

• ④ Ngokuvamile yenziwe ngethusi noma insimbi engagqwali ukuze isetshenziswe olwandle.

• ⑤Kufakwe emathangini enkonzo kawoyela kaphethiloli, emathangini kadizili, kanye nasezintanjeni zikawoyela we-hydraulic.

Amavalvu okuvala okusheshayo ayingxenye ebalulekile yezinhlelo zokuphepha kolwandle. Ezimweni eziphuthumayo, asiza ekuvimbeleni ukusabalala komlilo futhi anciphise umonakalo, avikele abasebenzi kanye nemishini.

Iyini iValve Ezivala Ngokwayo

Ngakolunye uhlangothi, ivalvu ezivala ngokwayo ivala ngokuzenzakalelayo ngemva kokusebenza ngaphandle kokudinga amandla angaphandle noma ukulawula okude. Yakhelwe izinhlelo ezidinga ukuvimba ukugeleza koketshezi ngokuzenzakalelayo ngemva kokugcwalisa noma ukukhipha amanzi sekuqediwe.

Uhlobo oluvame kakhulu ivalvu yokubuyisela intwasahlobo, lapho isibambo kufanele sibanjwe sivulekile ngesandla. Uma sesikhululiwe, indlela yentwasahlobo iphoqa ivalvu ukuthi ivale. Lawa mavalvu avame ukutholakala ezindaweni zokugcwalisa uphethiloli, emigqeni yokukhipha amanzi, nasezindaweni zokukhipha amanzi emikhunjini nasemishinini yezimboni.

Izici Eziyinhloko Zamavalvu Azivalayo

• ①Ivala ngokuzenzakalelayo lapho isibambo sikhululwa.

• ②Kuvimbela ukugcwalisa ngokweqile ngengozi noma ukukhishwa okuqhubekayo.

• ③Isakhiwo esilula, kulula ukusisebenzisa nokuyinakekela.

• ④Ilungele iziteshi ze-bunker, imigqa yokudlulisa uphethiloli, kanye nezinhlelo zokukhipha amanzi emadekhini.

Nakuba kungahloselwe ukuvalwa okuphuthumayo, ama-valve azivala ngokwawo athuthukisa ukuphepha kokusebenza futhi anciphise ingozi yokuchitheka ngesikhathi sokusebenza okuvamile.
