Iyini intwasahlobo yevalvu yemoto
Intwasahlobo yevalvu yemoto iyingxenye ebalulekile yenjini yemoto, etholakala phakathi kwekhanda lesilinda kanye nesihlalo sentwasahlobo yenduku yevalvu. Umsebenzi wayo oyinhloko ukuqinisekisa ukuthi ivalvu ihlezi ngesikhathi futhi ifakwe kahle ukuvimbela ivalvu ukuthi ingashayi ngesikhathi sokudlidliza kwenjini, ngaleyo ndlela kubhubhise ukuvalwa kwayo .
Iziphethu zamavalvu zivame ukwenziwa ngocingo lwensimbi oluhlanganisiwe olusezingeni eliphezulu futhi ziphathwa ngokushisa ukuze kwandiswe amandla azo okukhathala. Ukuze kuvinjelwe ukugqwala kwesiphethu, ubuso buzogqunywa nge-galvanized noma nge-phosphating. Iziphetho zalo ezimbili kufanele zibe yisicaba futhi ziqonde ngqo ku-axis yesiphethu ukuvimbela ukugoba ngesikhathi senqubo yokusebenza.
Ukwakheka kanye nokukhethwa kwezinto zentwasahlobo yamavalvu kunomthelela obalulekile ekusebenzeni kwenjini. Ukuze kugwenywe ukugqama, izinjini zesimanje zisebenzisa kakhulu iziphethu zephimbo eziguquguqukayo noma iziphethu ezimbili ezifakwe ngaphakathi. Ukwakheka kwentwasahlobo yamavalvu amabili kufaka phakathi iziphethu ezimbili ezijikelezwe ngokuphambene ngaphakathi nangaphandle. Ukuqina kwentwasahlobo yangaphandle kukhulu, okungavimbela ngempumelelo ukugqama, futhi lapho intwasahlobo eyodwa iphukile, enye ingaqhubeka nokusebenza ukuqinisekisa ukuvalwa okuvamile kwevalvu .
Umgomo osebenzayo wesiphethu se-valve ukuqinisekisa ukuthi i-valve ixhunywe eduze nesihlalo se-valve ngokunqoba amandla angaphakathi ngesikhathi senqubo yokuvala i-valve nokuvimbela i-valve ukuthi ingagxumi ngaphansi komthwalo wengcindezi. Ngaphezu kwalokho, isiphethu se-valve singalawula nokuhamba kwe-valve ukuze kugwenywe ukuhlukaniswa kwendlela ye-valve .
Ngamafuphi, yize isipilingi se-valve sincane enjinini, indima yaso ibalulekile ukuqinisekisa ukusebenza okuvamile kanye nokusebenza okuzinzile kwenjini.
Indima eyinhloko yesiphethu se-valve yemoto ihlanganisa izici ezilandelayo:
Qinisekisa ukuthi isihlalo se-valve sisebenza ngesikhathi esifanele futhi silingana kahle: isiphethu se-valve singaqinisekisa ukuthi i-valve ingafakwa kahle nesihlalo se-valve noma indandatho yesihlalo se-valve uma ivaliwe, ivimbele i-valve ukuthi ingagxumi lapho injini idlidliza, ukuze kugcinwe uphawu oluhle.
ukunqoba amandla angenawo ugesi: lapho i-valve ivulwa, indlela yokusebenza kwe-valve izokhiqiza amandla angenawo ugesi, isiphethu se-valve singanqoba la mandla angenawo ugesi ukuqinisekisa ukuthi izingxenye zokudlulisa zihlala zilawulwa yi-CAM futhi azihlukaniswanga .
ukuvimbela ukuzwakala kanye nokuphaphazela: ukuze kuvinjelwe ukuzwakala kwentwasahlobo yamavalvu enkambisweni yokusebenza, ezinye izinjini zisebenzisa isakhiwo sentwasahlobo yamavalvu amabili, ukujikeleza kwentwasahlobo okubili kuphambene, okungavimbela ukudlidliza kwentwasahlobo, kuthuthukise ukuzinza kwentwasahlobo yamavalvu.
Amandla okukhathala athuthukisiwe kanye nokuthembeka: Iziphethu zamavalvu zivame ukwenziwa ngocingo lwensimbi oluhlanganisiwe olusezingeni eliphezulu futhi ziphathwe ngokushisa ukuze kuthuthukiswe ukumelana kwazo nokukhathala. Ukuze kuvinjelwe ukugqwala, ubuso buqiniswa nge-galvanized noma i-phosphate.
Zivumelanise nokucindezeleka okuphezulu okuguquguqukayo kanye nokusebenza kwesivinini esikhulu : ngenjini ithuthukiswa ngamandla aphezulu, ngesivinini esikhulu, iziphethu zamavalvu zidinga ukumelana nokucindezeleka okuphezulu okuguquguqukayo kanye nesivinini sokuphendula okusheshayo. Ngakho-ke, ukwakheka nokukhiqizwa kweziphethu zamavalvu kudinga izidingo zobuchwepheshe eziphakeme .
