AmavalvuAzisetshenziswa kabanzi kuphela ezimbonini ezahlukahlukene, kodwa futhi zisebenzisa izindawo ezahlukene, futhi amanye ama-valve ezindaweni zokusebenza ezinzima avame ukuba nezinkinga. Njengoba ama-valve eyimishini ebalulekile, ikakhulukazi kwamanye ama-valve amakhulu, kunzima kakhulu ukuwalungisa noma ukuwashintsha uma sekunenkinga. Ngakho-ke, kubaluleke kakhulu ukwenza umsebenzi omuhle wokulungisa nokulungisa nsuku zonke. Ake sibheke amanye amathiphu mayelana nokulungisa ama-valve.
1. Ukugcinwa nokuhlolwa kwansuku zonke kwe-amavalvu
1. Ivalvu kufanele igcinwe ekamelweni elomile nelinomoya, futhi zombili izinhlangothi zendlela kumele zivinjwe.
2. Amavalvuokugcinwe isikhathi eside kufanele kuhlolwe njalo, ukungcola kufanele kususwe, bese kuthi uwoyela ovimbela ukugqwala ugcotshwe endaweni yokucubungula.
3. Ngemva kokufakwa, kufanele kwenziwe ukuhlolwa okuvamile, futhi izinto eziyinhloko zokuhlola yilezi:
(1) Ukuguguleka kwendawo yokuvala.
(2) Ukuguguleka kwentambo ye-trapezoidal yesiqu kanye ne-stem nut.
(3) Kungakhathaliseki ukuthi isigcwalisi siphelelwe yisikhathi futhi asisebenzi, uma sonakele, kufanele sishintshwe ngesikhathi.
(4) Ngemva kokuba ivalvu isilungisiwe futhi yahlanganiswa, kufanele kwenziwe ukuhlolwa kokusebenza kokuvala.
2. Umsebenzi wokulungisa lapho ivalvu igcotshwe ngamafutha
Ukugcinwa kobungcweti kweivalvuNgaphambi nangemva kokushisela kanye nokukhiqiza kudlala indima ebalulekile ekusesheni ivalvu ekukhiqizeni nasekusebenzeni, futhi ukulungiswa okufanele nokuhlelekile nokusebenzayo kuzovikela ivalvu, kwenze ivalvu isebenze ngendlela evamile futhi kwandise impilo yevalvu. Ukugcinwa kwevalvu kungase kubonakale kulula, kodwa akunjalo. Ngokuvamile kunezici zomsebenzi ezinganakwa.
1. Uma ivalvu igcotshwa ngamafutha, inkinga yokujova ngamafutha ivame ukunganakwa. Ngemva kokuba isibhamu sokujova ngamafutha sigcwaliswe ngophethiloli, umqhubi ukhetha ivalvu kanye nendlela yokuxhumanisa ukujova ngamafutha ukuze enze umsebenzi wokujova ngamafutha. Kunezimo ezimbili: ngakolunye uhlangothi, inani lokujova ngamafutha lincane, ukujova ngamafutha akwanele, futhi indawo yokuvala igugile ngokushesha ngenxa yokuntuleka kokugcoba. Ngakolunye uhlangothi, ukujova ngamafutha ngokweqile kubangela imfucuza. Lokhu kungenxa yokuthi akukho ukubalwa okunembile kwamandla okuvala amavalvu ahlukene ngokohlobo lwevalvu. Amandla okuvala angabalwa ngokosayizi nohlobo lwevalvu, bese inani elifanele lamafutha lingajovwa ngokufanele.
Okwesibili, uma ivalvu igcotshwa ngamafutha, inkinga yokucindezela ivame ukunganakwa. Ngesikhathi sokusebenza kokujova ngamafutha, ingcindezi yokujova ngamafutha iyashintsha njalo eziqongweni nasezigodini. Ingcindezi iphansi kakhulu, ukuvuza kwesivalo noma ukucindezeleka kokuhluleka kwesivalo kuphakeme kakhulu, imbobo yokujova ngamafutha ivinjiwe, igrisi esesivalweni iyaqina, noma indandatho yokuvala ivaliwe ngebhola levalvu nepuleti levalvu. Ngokuvamile, lapho ingcindezi yokujova ngamafutha iphansi kakhulu, igrisi elijoviwe ligeleza kakhulu phansi kwesivalo sevalvu, okuvame ukwenzeka kumavalvu amancane esangweni. Uma ingcindezi yokujova ngamafutha iphakeme kakhulu, ngakolunye uhlangothi, hlola umlomo wokujova ngamafutha, bese uwushintsha uma imbobo yamafutha ivinjiwe; Ngakolunye uhlangothi, ukuqina kwamafutha, lapho kusetshenziswa khona ikhambi lokuhlanza ukuthambisa ngokuphindaphindiwe igrisi yokugova ehlulekile bese uyishintsha ngegrisi entsha. Ngaphezu kwalokho, uhlobo lokugova kanye nezinto zokuvala nazo zithinta ingcindezi yamafutha, izinhlobo ezahlukene zokuvala zinengcindezi yamafutha ehlukene, ngokuvamile, ingcindezi yamafutha yesivalo esiqinile iphakeme kunesivalo esithambile.
Ukwenza umsebenzi ongenhla kukholakala ukuthi kuyasiza kakhulu ekwandiseni impilo yenkonzo ye-ivalvu, futhi ngesikhathi esifanayo, kunganciphisa nezinkinga eziningi ezingadingekile.
