Uyini umehluko phakathi kwevalvu yomhlaba kanye nevalvu yesango?

I-globe valve kanye ne-gate valve kufana ngokubukeka, futhi kokubili kunomsebenzi wokunqamula epayipini, ngakho abantu bavame ukuzibuza, uyini umehluko phakathi kwe-globe valve kanye ne-gate valve?

Ivalvu yeglobe, ivalvu yesango,ivalvu yebhabhathane, i-check valve kanye ne-ball valve konke kuyizingxenye zokulawula ezibalulekile ezinhlelweni ezahlukene zamapayipi. Uhlobo ngalunye lwe-valve luhlukile ngokubukeka, isakhiwo kanye nokusetshenziswa okusebenzayo. Kodwa i-globe valve kanye ne-gate valve kufana ngesimo, futhi ngesikhathi esifanayo kunomsebenzi wokunqamula epayipini, ngakho-ke kuzoba nabangani abaningi abangenawo ukuxhumana okuningi ne-valve abazodida laba bobabili. Eqinisweni, uma ubheka ngokucophelela, umehluko phakathi kwe-globe valve kanye ne-gate valve mkhulu kakhulu. Lesi sihloko sizokwethula umehluko phakathi kwe-globe valve kanye ne-gate valve.

1. Isimiso sokusebenza esihlukile phakathi kwe-globe valve kanye ne-gate valve
Uma ivalvu yomhlaba ivuliwe futhi ivaliwe, ijika esondweni lesandla, isondo lesandla lizojikeleza futhi liphakanyiswe kanye nesiqu sevalvu, kuyilapho ivalvu yesango izojika isondo lesandla ukuze iphakamise i-valve lever, futhi indawo yesondo lesandla ngokwayo ayishintshi.

II-valve yesango ehleli ngerabhainezimo ezimbili kuphela: ukuvulwa okugcwele noma ukuvalwa okugcwele okunesikhathi eside sokuvulwa nokuvalwa; ukunyakaza kwevalvu yomhlaba kuncane kakhulu, futhi ipuleti levalvu lingapakwa endaweni ethile ukuze kulawulwe ukugeleza, kuyilapho ivalvu yesango inganqanyulwa kuphela ngaphandle kweminye imisebenzi.

2. Umehluko wokusebenza phakathi kwevalvu yomhlaba kanye nevalvu yesango
Ivalvu yomhlaba inganqunywa futhi isetshenziselwe ukulawula ukugeleza. Ukumelana koketshezi kwevalvu yomhlaba kukhulu kakhulu, futhi kunzima ukuyivula nokuyivala, kodwa ngoba ipuleti levalvu lifushane ukusuka ebusweni bokuvala, ngakho-ke ukugoba kokuvula nokuvala kufushane.

Ivalvu yesango le-BS5163 ingavulwa futhi ivalwe ngokuphelele kuphela. Uma ivulwe ngokuphelele, ukumelana kokugeleza kwe-medium emgudwini womzimba wevalvu kucishe kube ngu-0, ngakho-ke ukuvulwa nokuvalwa kwevalvu yesango kuzoba lula kakhulu, kodwa isango likude kakhulu nendawo yokuvala, futhi isikhathi sokuvula nokuvala side kakhulu.

3. Umehluko wokuqondisa kokufakwa kwe-globe valve kanye ne-gate valve
Ukugeleza kwevalvu yesango eliqinile kuzo zombili izinkomba kunomphumela ofanayo, ukufakwa akunazo izidingo zesiqondiso sokungenisa nokuthumela ngaphandle, i-medium ingageleza kuzo zombili izinkomba.

Ivalvu yomhlaba idinga ukufakwa ngokuhambisana ngqo nesiqondiso sophawu lomcibisholo womzimba wevalvu. Kukhona umbandela ocacile mayelana nesiqondiso sokungena nokuphuma kwevalvu yomhlaba, futhi ivalvu ethi “three to” ichaza ukuthi isiqondiso sokugeleza kwevalvu yokuma sisetshenziswa kusukela phezulu kuya phansi.

4. Umehluko wesakhiwo phakathi kwevalvu yomhlaba kanye nevalvu yesango
Isakhiwo sevalvu yesango sizoba yinkimbinkimbi kakhulu kunevalvu yembulunga. Ngokubukeka kwayo ububanzi obufanayo, ivalvu yesango kufanele ibe phezulu kunevalvu yembulunga, kanti ivalvu yembulunga kufanele ibe yinde kunevalvu yesango. Ngaphezu kwalokho, ivalvu yesango inawoIsiqu EsikhuphukayofuthiIsiqu Esingavuki, ivalvu yomhlabathi ayikwenzi lokho.
