Isebenza kanjani ivalve yebhola elintantayo?

Umklamo we-valve yebhola elintantayo

A i-valve yebhola elintantayookuthiwa yindilinga efana nebhola “entantayo” ngokukhululekile ngaphakathi komzimba wevalvu, ecindezelwa phakathi kwezihlalo ezimbili eziguquguqukayo kuyilapho ilenga oketshezini.Okuvame ukwenziwa ivalvu yebhola elintantayo ngesikhathi sokusebenza ukuntanta kancane kwehle nomfula, okubangela ukuthi indawo yokuhlala icindezeleke ngaphansi kwebhola.Uma indawo yokuhlala ihlakazeka, ibhola lintanta liye esiqwini sensimbi ukuze livaleke.Lokhu kunikeza ukwehluleka-ukuphepha ngaphakathi komklamo.

Uhlelo luphinde lufake isiqu emzimbeni wevalvu esixhuma endaweni engaphezulu kwebhola futhi sivumele ibhola ukuthi lijikeleze ngamadigri angama-90.Lesi siqu sivumela ibhola ukuthi lihambe liye ngaseceleni lapho umfutho okhuphuka nomfula usebenza phezu kwalo, kuyilapho esinye isihlalo esingezansi sithuthukisa ukucinana kophawu lwevalvu.Lokhu kuvumela i-valve ukuthi ivale lapho uketshezi lugeleza kunoma iyiphi indlela.

Ibhola ngokwalo linembobo okudlula kuyo uketshezi ngokukhululeka uma liqondaniswe kahle nawo womabili amaphethelo evalvu.Le mbobo, lapho i-perpendicular, ivala i-valve.Uma le mbobo ikunoma iyiphi enye indawo, uketshezi luzoqhubeka nokugeleza kuyo.I-valve yebhola elintantayo ingakwazi ukuma, isabalalise futhi iguqule indlela uketshezi olugeleza ngayo ngaphakathi kwepayipi, izici zayo eziyinhloko kuwumklamo wokuvala izihlalo, okhulula ngokuzenzakalelayo ukucindezela, ukuvala ngokuthembekile lapho amanzi ageleza emuva futhi esebenza njengethuluzi lokukhiya.

Ingcindezi isebenza kuvalvu evaliwe engemuva kwesihlalo esikhuphuka nomfula kanye nebhola, okuphoqa ibhola libheke esihlalweni esingezansi.Lawa mandla akhubaza futhi akhawulele izihlalo zamavalvu.Lokhu kuguqulwa kwesikhashana kuklanywe ekwakhiweni kwezihlalo, kusetshenziswa amandla agciniwe ukuze kushintshe ukuma kwawo okwesikhashana ukuze kugcinwe uphawu lapho amazinga okushisa noma ukucindezela kushintsha.

UBUHLE KANYE NEBUBI

Ama-valve ebhola antantayoasetshenziswa kakhulu ezinhlelweni ezidinga amavalvu anomfutho ophakathi nendawo ukuya kophansi, futhi afaneleka kahle kukho kokubili uketshezi namagesi.Ilula futhi iyonga, indawo yokuhlala ayikwazi ukusebenza ngokuphepha nangempumelelo ngamabhola asindayo.

• Izinzuzo zihlanganisa:
• Umklamo ohlangene
• Ukusebenza kahle kwezindleko
• Yenza ngokwezifiso
• Ukumelana nokugeleza okuncane
• Imisebenzi yokubeka uphawu enokwethenjelwa
• Ukwakhiwa okungeyona inkimbinkimbi

Ukungalungi kuhlanganisa:

• Ukuthembela ngokuphelele ezihlalweni ezansi nomfula lapho uthwele umthwalo ophakathi nendawo.
• Kunzima ukusebenza uma umfutho okhuphuka nomfula uphezulu.
• Ukuhlala kubamba ngokuqondile amandla adonsela phansi ebhola, ngakho ayikwazi ukumelana nokucindezela okuphezulu noma amabhola amakhulu.

Isebenza kanjani ivalve yebhola elintantayo?

Ama-valve ebhola antantayoasetshenziswa yi-shaft, noma isiqu, esinamathiselwe phezulu ebholeni elijika libe ngama-degree angu-90 (ikota yokujika).Njengoba ibhola lizungeza, imbobo imbozwa noma yembulwe udonga lomzimba we-valve, noma ukukhulula noma ukumisa ukugeleza kwemidiya.Isiqu sinamathiselwe ngokukhululekile ngokwanele ebholeni ukuthi, njengoba ibhola lizungeza ku-axis yalo, ukucindezela kokugeleza kuphushela ibhola esihlalweni sayo esingezansi, okwenza uphawu oluqinile.Ngenxa yalesi sizathu, ama-valve amabhola antantayo angase angavali kahle uma kunengcindezi ephansi kakhulu ngemva kokuguga kwezihlalo ezithile.Lokhu kungenxa yokuthi kungase kungabi nengcindezi eyanele yemidiya yokuphoqa ibhola esihlalweni esingezansi ukuze kudaleke isivalo esiqinile.Kodwa-ke, ezinsizeni eziningi ukucindezela komfula kwanele ukugcina uphawu oluqinile ngemva kokuba izihlalo seziqalile ukuguga.

I-RXVALnikeza izinhlobo ze-valve yebhola elintantayo njenge-valve yebhola elintantayo elilodwa, izingcezu ezimbili ze-valve yebhola elintantayo, izingcezu ezintathu ze-valve yebhola elintantayo.Ngempahla ehlukene, ingcindezi nokubhekana nesihlalo.Sicela usithinte uma unesidingo sala mavalvu.
