Uyini umehluko phakathi kwevalvu yephasi nevalvu yesango?

Ivalvu ye-globe ne-gate valve zifana ngokubukeka, begodu zombili zinomsebenzi wokusika iphayiphi, ngalokho abantu bavame ukuzibuza, ngimuphi umehluko phakathi kwe-globe valve ne-gate valve?

Ivalvu ye-globe, ivalvu yesango,ivalvu yevivane, i-valve yokuhlola kanye ne-ball valve zoke zizinto zokulawula eziqakathekileko eenhlelweni ezihlukahlukeneko zamapayipi. Umhlobo ngamunye wevalvu uhlukile ngokubukeka, ukwakheka kanye nokusetjenziswa kwawo. Kodwana i-globe valve ne-gate valve zinokufana ngejamo, begodu ngesikhathi esifanako zinomsebenzi wokusika epayipini, njeke kuzokuba nabangani abanengi abangathintani khulu ne-valve bazokudida bobabili. Kuhlekuhle, nawuqalisisa, umehluko phakathi kwevalvu yephasi nevalvu yesango mkhulu khulu. I-atikili le izokwethula umehluko phakathi kwevalvu yephasi nevalvu yesango.

1. Umthetho wokusebenza ohlukileko hlangana ne-globe valve ne-gate valve
Lokha i-globe valve nayivulwa begodu ivalwa, ivula isondo lesandla, isondo lesandla lizakujikeleza begodu liphakame ndawonye nesiqu se-valve, ngesikhathi i-gate valve izokujika isondo lesandla ukuphakamisa i-valve lever, begodu ubujamo besondo lesandla ngokwalo buhlala bungatjhuguluki.

IIvalvu yesango elihlezi ngerabhainemibuso emibili kwaphela: ukuvulwa okuzeleko nofana ukuvala okuzeleko ngesikhathi eside sokuvulwa nokuvala; ukunyakaza kwevalvu ye-globe mncani khulu, begodu ipuleti yevalvu ingaphakwa endaweni ethileko ukunyakaza ukulawulwa kokugeleza, lokha ivalvu yesango inganqunywa ngaphandle kweminye imisebenzi.

2. Umehluko wokusebenza hlangana ne-globe valve ne-gate valve
Ivalvu ye-globe ingasikwa bese isetjenziselwa ukulawula ukugeleza. Ukujamelana noketshezi kwe-globe valve kukhulu, begodu kubudisi ukuyivula nokuyivala, kodwana ngombana ipuleti ye-valve imfitjhani ukusuka ebusweni bokuvala, njeke ukuvula nokuvala kwe-stroke kufitjhani.

Ivalvu yesango le-BS5163 ingavulwa begodu ivalwe ngokupheleleko kwaphela. Lokha nayivuliwe ngokupheleleko, ukujamelana nokugeleza kwe-medium emzileni womzimba wevalvu kupheze kube ngu-0, ngalokho ukuvulwa nokuvalwa kwevalvu yesango kuzokuba lula khulu, kodwana isango likude nendawo yokuvala, begodu isikhathi sokuvula nokuvala side.

3. Umehluko wendlela yokugeleza kokufakwa kwe-globe valve ne-gate valve
Ukugeleza okuqinileko kwevalvu yesango emahlangothini womabili kunomphumela ofanako, ukufakwa akunazidingo zokungenisa nokuthumela ngaphandle, umphakathi ungageleza emahlangothini womabili.

Ivalvu ye-globe itlhoga ukufakwa ngokuya ngokuqinileko kwendlela yomcibisholo womzimba wevalvu. Kunomthetho ocacileko mayelana nendlela yokungena nokuphuma kwevalvu ye-globe, begodu ivalvu “emithathu ukuya” ibeka bona indlela yokugeleza kwevalvu yokumisa isetjenziswa ukusuka phezulu ukuya phasi.

4. Umehluko wesakhiwo hlangana nevalvu ye-globe nevalvu yesango
Isakhiwo sevalvu yesango sizokuba yinkimbinkimbi ukudlula ivalvu ye-globe. Ngokuya ngokubonakala kobubanzi obufanako, ivalvu yesango kufanele ibe phezulu kunevalvu ye-globe, begodu i-valve ye-globe kufanele ibe yinde kune-valve yesango. Ngaphezu kwalokho, ivalvu yesango ineIsiqu esikhuphukakokunyeIsiqu esingaphakami, ivalvu ye-globe ayikwenzi lokho.
