Imigomo nezincazelo zamavalvu okuphepha BESA

Imigomo nezincazelo ngokuhambisana ne-EN ISO 4126-1

1) I-valve yokuphepha

Ivalvu evele, ngaphandle kosizo lwanoma yimaphi amandla ngaphandle kwalolo ketshezi oluthintekayo, ikhiphe uketshezi oluningi ukuze kuvinjelwe ukweqiwa kwengcindezi enqunywe kusengaphambili, futhi eklanyelwe ukuvala kabusha nokuvimbela ukugeleza koketshezi ngemva kwalokho. izimo zokucindezela ezijwayelekile zesevisi zibuyiselwe.

2) Beka ingcindezi

Ingcindezi enqunywe kusengaphambili lapho i-valve yokuphepha ngaphansi kwezimo zokusebenza iqala ukuvula.
Ukunqunywa kwengcindezi ebekiwe: ukuqala kokuvulwa kwe-valve yokuphepha (isikhathi lapho uketshezi luqala ukuphuma

kusuka ku-valve yokuphepha, ngenxa yokugudluzwa kwe-disc ekuxhumaneni nendawo yokuvala yesihlalo) inganqunywa ngezindlela ezihlukahlukene (ukuchichima, i-pop, ama-bubbles), lezo ezithathwe BESA Zimi kanje:

ukusetha ngegesi (umoya, i-nitrogen, i-helium): ukuqala kokuvulwa kwe-valve yokuphepha kunqunywa
- ngokulalela igalelo lokuqala elizwakalayo
- ngokuchichima koketshezi lokuhlola oluphuma esihlalweni sevalvu;
ukusetha ngoketshezi (amanzi): ukuqala kokuvuleka kwevalvu yokuphepha kunqunywa ngokubona ngokubona ukugeleza kokuqala koketshezi oluphuma esihlalweni sevalvu.

Ingcindezi shall kulinganiswa kusetshenziswa i-gauge yokucindezela yesigaba sokunemba esingu-0.6 kanye nesilinganiso esigcwele se-1.25 kuya ku-2 izikhathi zokucindezela okufanele zikalwe.

I-3) Ingcindezi ephezulu evumelekile, i-PS

Ingcindezi enkulu impahla yakhelwe yona njengoba kucaciswe umenzi.

4) Ukucindezela ngokweqile

Ingcindezi iyanda ngaphezu komfutho obekiwe, lapho i-valve yokuphepha ifinyelela ukuphakama okucaciswe umenzi, ngokuvamile okuvezwa njengephesenti lokucindezela okumisiwe.

I-5) Ukucindezela kabusha

Inani lengcindezi emile yokungena lapho idiski iphinda isungula khona ukuthintana nesihlalo noma lapho ilifti iba uziro.

I-6) Ukucindezela kokuhlola okuhlukile okubandayo

Ingcindezi emile yokungena lapho i-valve yokuphepha isethwe ukuthi iqale ukuvula ebhentshini.

7) Ukunciphisa ingcindezi

Ingcindezi esetshenziselwa ukulinganisa i-valve yokuphepha enkulu noma elingana nokucindezela okumisiwe kanye nokucindezela ngokweqile.

I-8) Ingcindezi eyakhiwe emuva

Ingcindezi ekhona lapho kuphuma i-valve yokuphepha ebangelwa ukugeleza kwe-valve kanye nesistimu yokukhipha.

I-9) Ingcindezi yangemuva ephezulu

Ingcindezi ekhona lapho kuphuma i-valve yokuphepha ngesikhathi ucingo ludingeka ukuthi lusebenze.

10) Phakamisa

Ukuhamba kwangempela kwediski ye-valve kude nendawo evaliwe.

11) Indawo yokugeleza

Isilinganiso esincane sokugeleza kwesigaba esiphambanayo (kodwa hhayi indawo yekhethini) phakathi kwendawo yokungena nesihlalo esisetshenziselwa ukubala umthamo wokugeleza kwethiyori, ngaphandle kokubanjwa kunoma yikuphi ukuvinjelwa.
