Kusho ukuthini inani le-CV? Ungayikhetha kanjani i-valve yokulawula ngenani le-CV?

InisivalwanaUbunjiniyela, inani le-CV (i-flow coefflicredle) yokulawulwaisivalwanaKubhekiswa kuzinga lokuhamba ngevolumu noma isilinganiso sokugeleza kwesisindo sepayipi eliphakathi nendawo nge-valve ngayinye isikhathi seyunithi ngayinye nangaphansi kwezimo zokuhlola lapho ipayipi ligcinwa ekucindezelweni okungapheli. Okungukuthi, umthamo wokugeleza we-valve.

Inani eliphakeme le-flow coeffientled, the lawetha ukulahleka kwengcindezi njengoba uketshezi lugeleza phakathiisivalwana.

Inani le-CV le-valve kumele linqunywe ngokuhlola nokubala.

I-CVthandaIngabe ipharamitha ebalulekile yezobuchwepheshe ekala umthamo wokugeleza we-valve yokulawula ngaphansi kwemibandela ethile. Inani le-CV alikho kuphela elibonisa ukusebenza kwe-valve uqobo, kepha lihlobene ngokuqondile nokwakheka nokusebenza okusebenzayo kohlelo lokulawula uketshezi.

Incazelo imvamisa ngokususelwa ezimweni ezijwayelekile ezilandelayo:isivalwanaKuvulwa ngokuphelele, umehluko wengcindezi yi-1 lb / in² (noma i-7kpa) emaphethelweni, kanti uketshezi lungu-60 ° F) lwamanzi ahlanzekile, lapho ivolumu yamanzi (ngamafutha aseMelika) idlula ngenani le-CV le-VV. Kumele kwaziwe ukuthi i-Coff Coeffled eChina ivame ukuchazwa ohlelweni lweMetric, ngophawu lwe-KV, nobudlelwano nenani le-CV yi-CV = 1.156KV.

Unganquma kanjani i-caliber ye-valve ngenani le-CV

1. Bala inani le-CV oyifunayo:

Ngokuya ngezidingo ezithile zohlelo lokulawula uketshezi, njengokugeleza, ukucindezela okuhlukile, okuphakathi nezinye izimo, inani le-CV elidingekayo libalwa kusetshenziswa ifomula noma isoftware ehambisanayo. Lesi sinyathelo sibheka izici ezinjengezakhiwo ezibonakalayo zoketshezi (isib. I-viscosity), izimo zokusebenza (isib. Ukushisa, ingcindezi), nengcindezelo), nengcindezi) kanye nendawo ye-valve.

2. Khetha ububanzi be-valve efanelekile:

Ngokusho kwenani elibaliwe le-CV elifiselekayo kanye nenani le-CV elilinganiselwe le-valve, kukhethwe ububanzi be-valve efanelekile. Inani le-CV elilinganiselwe le-valve elikhethiwe kufanele lilingane no noma likhulu kancane kunenani le-CV elidingekayo ukuqinisekisa ukuthi i-valve ingahlangabezana nesidingo soqobo sokugeleza. Ngasikhathi sinye, kuyadingeka futhi ukubheka ezinye izinto ezinjengezinto ezibonakalayo, ukwakheka, ukubekwa uphawu kokusebenza, kanye nemodi yokusebenza ye-valve ukuqinisekisa ukuthi ukusebenza okuphelele kwe-valve kuhlangabezana nezidingo zohlelo.

3. Ukuqinisekiswa nokulungiswa:

Ngemuva kokukhethwa kokuqala kweisivalwanaCaliber, ukuqinisekiswa okudingekayo nokulungiswa kufanele kwenziwe. Lokhu kufaka ukuqinisekisa ukuthi ukusebenza kwe-flow ye-valve kuhlangabezana nezidingo zohlelo ngokusebenzisa ukubalwa kokulingisa noma ukuhlolwa kwangempela komhlaba. Uma kutholakala ukuphambuka okukhulu, kungadingeka ukuthi iphindise inani le-CV noma ilungise ububanzi be-valve.

Ukubeka kafushane

Ohlelweni lokuhlinzekwa kwamanzi kwesakhiwo, uma i-valve yokulawula ingahlangabezani nenani elidingekayo le-CV, iphampu lamanzi lingaqala futhi liyeke kaningi noma ligijime ngomthwalo omkhulu ngaso sonke isikhathi. Akukhona nje kuphela ukuthi lokhu kungcola kwamandla kagesi, kepha ngenxa yokushintshashintsha njalo kwengcindezi, kungaholela ekuxhumeni okuthe xaxa kwamapayipi, ukuvuza, futhi kungadala ukulimala kwephampu ngenxa yokugcwala isikhathi eside.

Ngamafuphi, inani le-CV le-valve yokulawula liyinkomba ebalulekile yokukala umthamo wayo wokugeleza. Ngokubala ngokunembile inani le-CV futhi unqume i-valve caliber efanelekile ngokusekelwe kulo, ukuqina kanye nokusebenza kahle kohlelo lokulawula uketshezi kungaqinisekiswa. Ngakho-ke, kwinqubo yokukhethwa kwe-valve, ukwakheka kohlelo kanye nokwenza kahle ukusebenza, ukunakwa okugcwele kufanele kukhokhwe ekubalweni kanye nokusetshenziswa kwenani le-CV.
