Ama-valve esango

Amavalvu esango aklanyelwe ngokuyinhloko ukuqala noma ukumisa ukugeleza, futhi lapho ukugeleza komugqa oqondile woketshezi kanye nomkhawulo omncane wokugeleza kuyadingeka. Ensimini, lawa mavalvu ngokuvamile avuleka noma avaleke ngokuphelele.

I-disk ye-valve yeSango isuswa ngokuphelele lapho i-valve ivuliwe ngokugcwele; idiski idonswe ngokugcwele kuBonnet yevalvu. Lokhu kushiya imbobo yokugeleza ngevalvu kububanzi obufanayo bangaphakathi njengesistimu yamapayipi lapho kufakwa khona ivalvu. I-valve yesango ingasetshenziselwa uketshezi oluningi futhi inikeza isigxivizo esiqinile lapho ivaliwe.

Ukwakhiwa kwe-valve yeSango

Amavalvu esango aqukethe izingxenye ezintathu eziyinhloko: umzimba, ibhonethi, kanye nokunquma. Umzimba uvame ukuxhunywa kwezinye izinto ngokuxhunywa okune-flanged, screwed noma okushiselwe. Ibhonethi, equkethe izingxenye ezihambayo, ixhunywe emzimbeni, ngokuvamile ngamabhawudi, ukuze ivumele ukulungiswa. I-valve trim iqukethe isiqu, isango, i-disc noma i-wedge kanye namasongo esihlalo.

Amadiski e-valve yeSango

Ama-valve esango atholakala ngamadiski noma ama-wedges ahlukene. Ukushintshashintsha kwama-valve eSango kuvame ukwenziwa uhlobo lwe-wedge esetshenziswayo.

Okuvame kakhulu kwakuyi:

• I-Solid wedge iyidiski esetshenziswa kakhulu ngobulula namandla ayo.
  I-valve enalolu hlobo lwe-wedge ingafakwa endaweni ngayinye futhi ifanele cishe lonke uketshezi. Iweji eqinile iyisiqephu esisodwa esiqinile, futhi ilungele ukugeleza kwesiyaluyalu.
• I-Flexible wedge iyidiski enocezu olulodwa olusike umjikelezo ukuze kuthuthukiswe ikhono lokulungisa amaphutha noma izinguquko ku-engeli phakathi kwezihlalo.
  Ukwehliswa kuzohluka ngobukhulu, ukuma nokujula. Ukusika okungajulile, okuncane kunikeza ukuguquguquka okuncane kodwa kugcina amandla.
  Ukusika okujulile nokubanzi, noma ikhefu lokuphonswa phakathi, kushiya into encane phakathi, okuvumela ukuguquguquka okwengeziwe, kodwa kubeke engcupheni amandla.
• I-Split wedge iyazilungisa futhi iqondanisa yona nezinhlangothi zombili. Lolu hlobo lwe-wedge luqukethe ukwakhiwa okuyiziqephu ezimbili ezihlala phakathi kwezihlalo ezicijile emzimbeni we-valve. Lolu hlobo lwe-wedge lufanele ukwelashwa kwamagesi angajiki noketshezi emazingeni okushisa avamile, ikakhulukazi uketshezi olubolayo.

Isiqu se-valve yeSango

Isiqu, esixhumanisa isondo lesandla nediski komunye nomunye, sinesibopho sokuma kahle kwediski. Iziqu zivame ukwenziwa ngomgunyathi, futhi zixhunywe kudiski ngokucushwa noma amanye amasu. Ukuvimbela ukuvuza, endaweni yophawu, ukuqedwa okuhle kwesiqu kuyadingeka.

Ama-valve esango ahlukaniswa ngokuthi:

• Isiqu Esikhuphukayo
• Isiqu esingavuki

Ngevalvu yohlobo lwe-Rising Stem, isiqu sizokhuphuka ngaphezu kwesondo lesandla uma i-valve ivuliwe. Lokhu kwenzeka, ngoba isiqu siyafakwa futhi sihlanganiswe nemicu yeJoka. Ijoka liyingxenye ebalulekile evela ku-Rising Stem valve futhi lifakwa kuBonnet.

Ngevalvu yohlobo lwe-non-Rising Stem, akukho ukunyakaza kwe-stem ukuya phezulu uma i-valve ivuliwe. Isiqu sithululelwa kudiski. Njengoba isondo lesandla esiqwini lizungeziswa, idiski ihambela phezulu noma phansi kwesiqu emiculweni kuyilapho isiqu sihlala simile simile.

Kumenyu enkulu "Amavalvu" uzothola izixhumanisi zemidwebo enemininingwane (emikhulu) yazo zombili izinhlobo zeziqu.

Izihlalo zevalvu yeSango

Izihlalo zamavalvu eSango kungenzeka zihlinzekwe ngokuhlangene nomzimba wevalvu noma ohlotsheni lwendawo yokuhlala. Ukwakhiwa kweringi yezihlalo kunikeza izihlalo okungenzeka ukuthi zicushwe endaweni noma zicindezelwa endaweni bese zifakwa uphawu ezishiselwe emzimbeni wevalvu. Indlela yokugcina yokwakha inconywa ngenkonzo yokushisa ephezulu.

Izihlalo ezihlanganisiwe zihlinzeka ngesihlalo sempahla efanayo yokwakha njengendikimba ye-valve kuyilapho izihlalo ezicindezelwe noma ezifakwe phakathi zivumela ukuhluka. Amaringi anobuso obuqinile angase ahlinzekwe lapho edingeka khona.

Izinzuzo kanye Nemibi yama-valve eSango

Izinzuzo:

• Izici ezinhle zokuvala
• Ama-valve esango ane-bidirectional ngakho-ke angasetshenziswa ezinhlangothini ezimbili
• Ukulahlekelwa kwengcindezi nge-valve kuncane

Ububi:

• Azikwazi ukuvulwa ngokushesha noma ivalwe
• Ama-valve esango awafanele ukulawulwa noma ukugeleza kwe-throttle
• Zizwela ukudlidliza endaweni evulekile
