Ukulungiselela phambi kofakelo:
1. Qinisekisa ukuba umbhobho kwindawo yofakelo lweivalve yebholaikwindawo yecoaxial, kwaye iiflange ezimbini kumbhobho kufuneka zigcinwe zidityanisiwe ukuqinisekisa ukuba umbhobho ungathwala ubunzima bevalve yebhola ngokwayo.Ukuba kufunyaniswe ukuba umbhobho awukwazi ukuthwala ubunzima bevalve yebhola, nikezela ngenkxaso ehambelanayo yombhobho ngaphambi kofakelo.
2. Ukuqinisekisa ukuba kukho ukungcola, i-welding slag, njl njl kwipayipi, umbhobho kufuneka uhlambuluke.
3. Jonga ipleyiti yegama leivalve yebhola, kwaye wenze imisebenzi yokuvula ngokupheleleyo kunye nokuvala ngokupheleleyo kwivalve yebhola ngamaxesha amaninzi ukuqinisekisa ukuba i-valve inokusebenza ngokuqhelekileyo, kwaye emva koko uhlolisise iinkcukacha zevalve ukuqinisekisa ukuba i-valve ilungile.
4. Susa isigqubuthelo esikhuselayo kuzo zombini iziphelo zevalvu, khangela ukuba umzimba wevalvu ucocekile, kwaye ucoce umngxuma womzimba wevalvu.Kuba umphezulu wokutywina wevalve yebhola ungqukuva, kwanobutyobo obuncinci bunokubangela umonakalo kumphezulu wokutywina.
Amanqaku ofakelo:
1. Naliphi na icandelo levalve yebhola linokufakwa ekupheleni komlambo, kunye nevalve yokubamba ibhola inokufakwa kuyo nayiphi na indawo kumbhobho.Ukuba ivalve yebhola ene-actuator (efana nebhokisi yegiya, i-electric-pneumatic actuator) imisiwe, kufuneka ifakwe ngokuthe nkqo, kwindawo yokungena kunye nokuphuma kwevalve.kwindawo ethe tye.
2. Kufakwe igasket phakathi kweflange yevalve yebhola kunye neflange yombhobho ngokweemfuno zoyilo lombhobho.
3. Iibholiti kwi-flange kufuneka ziqiniswe ngokulinganayo, ngokulandelelana kunye nokulinganisa.
4. Ukuba iivalve yebholasebenza nge-pneumatic, umbane kunye nezinye i-actuator, gcwalisa ukufakwa komthombo womoya kunye nokunikezelwa kwamandla ngokwemiyalelo.
