Ulwazi loFakelo lweValve eqhelekileyo #1

Ukuhlolwa phambi kofakelo lwevalvu

① Jonga ngononophelo ukuba iivalveimodeli kunye neenkcukacha ziyahlangabezana neemfuno zomzobo.
② Jonga ukuba ingaba isiqu sevalve kunye nediski yevalvu zinokuvulwa ngokulula, nokuba zixingekile okanye zijijekile.
③ Jonga ukuba ivalve yonakele kwaye ukuba umsonto wevalve ephothiweyo ichanekile kwaye iphelele na.
④ Jonga ukuba udibaniso lwesitulo sevalvu kunye nomzimba wevalvu luqinile, unxibelelwano phakathi kwediski yevalvu kunye nesitulo sevalvu, isigqubuthelo sevalvu kunye nomzimba wevalvu, kunye nesiqu sevalvu kunye nediski yevalvu.
⑤ Khangela ukuba i-valve gasket, ukupakisha kunye ne-fasteners (iibholiti) zifanelekile kwiimfuno zendlela yokusebenza.
⑥ Ivalve yokukhulula uxinzelelo oludala okanye ekudala ikho kufuneka ichithwe, kwaye uthuli, isanti kunye nobunye ubugoxo kufuneka bucocwe ngamanzi.
⑦ Susa isiciko se-port, khangela iqondo lokutywina, kwaye i-disc valve kufuneka ivalwe ngokuqinileyo.

Uvavanyo loxinzelelo lwevalve

Uxinzelelo oluphantsi, uxinzelelo oluphakathi kunye noxinzelelo oluphezulu kufuneka lube phantsi kovavanyo lwamandla kunye novavanyo lokuqina, kunye neevalve zensimbi yealloy nazo kufuneka zihlaziywe ngokujonga iqokobhe ngalinye, kwaye izinto kufuneka zihlaziywe.

1. Uvavanyo lwamandla evalve
Uvavanyo lwamandla evalve kukuvavanya ivalve kwindawo evulekileyo ukujonga ukuvuza kumphezulu ongaphandle wevalve.Kwiivalvu ezine-PN≤32MPa, uxinzelelo lovavanyo luyi-1.5 amaxesha oxinzelelo oluncinci, ixesha lokuvavanya alikho ngaphantsi kwe-5min, kwaye akukho kuvuza kwigobolondo kunye nokupakisha i-gland ukuba ifaneleke.

2. Uvavanyo lokuqina kwevalve
Uvavanyo lwenziwa ngevalve ivalwe ngokupheleleyo ukujonga ukuba kukho ukuvuza kumphezulu wokutywina wevalve.Uxinzelelo lovavanyo, ngaphandle kweevalvu zebhabhathane, iivalve zokujonga, iivalve ezisezantsi, kunye neevalvu ze-throttle, kufuneka ziqhutywe kuxinzelelo oluqhelekileyo.Xa uxinzelelo olusebenzayo lusetyenzisiwe, lunokuvavanywa kwakhona ngamaxesha e-1.25 yoxinzelelo lokusebenza, kwaye ifanelekile ukuba indawo yokutywina yediski ye-valve ayivuzi.
