A:Iivalvu zokhuseleko kunye neegeyiji zoxinzelelo zizinto ezibalulekileyo zejenereyitha zomphunga, kwaye zikwayenye yeziqinisekiso zokhuseleko kwizijenereyitha zomphunga.Ivalve yokhuseleko eqhelekileyo luhlobo lwesakhiwo se-ejection.Xa uxinzelelo lomphunga mkhulu kunoxinzelelo olulinganisiweyo, idiski yevalve iya kutyhala ivuleke.Emva kokuba idiski yevalve ishiya isihlalo sevalve, umphunga uya kukhutshwa ngokukhawuleza kwisingxobo;igeyiji yoxinzelelo isetyenziselwa ukubona uxinzelelo lokwenene kwijenereyitha yomphunga.Ubungakanani besixhobo, umqhubi ulungelelanisa uxinzelelo olusebenzayo lwejeneretha ye-steam ngokwexabiso elibonakalisiweyo le-gauge ye-pressure gauge, ukwenzela ukuba kuqinisekiswe ukuba i-generator ye-steam inokugqitywa ngokukhuselekileyo phantsi koxinzelelo oluvunyelwe ukusebenza.
Iivalve zokhuseleko kunye neegeyiji zoxinzelelo zizixhobo zokhuseleko, iivalvu zokhuseleko zizixhobo zokukhusela uxinzelelo, kwaye iigeyiji zoxinzelelo zizixhobo zokulinganisa.Ngokwemigangatho yokusetyenziswa kwenqanawa yoxinzelelo lwesizwe kunye neendlela zokulinganisa, ukulinganisa kufuneka kube yinyanzelo.
Ngokwemigaqo echaphazelekayo, ivalve yokhuseleko iya kulinganiswa ubuncinane kanye ngonyaka, kwaye igeyiji yoxinzelelo iya kulinganiswa rhoqo kwiinyanga ezintandathu.Ngokubanzi, liziko lokuhlola elikhethekileyo lendawo kunye neziko le-metrology, okanye unokufumana iarhente yovavanyo lomntu wesithathu ukufumana ngokukhawuleza ingxelo yokulinganisa yevalve yokhuseleko kunye negeyiji yoxinzelelo.
Ngexesha lenkqubo yokulinganisa i-valve yokhuseleko kunye nemilinganiselo yoxinzelelo, umenzi kufuneka anike ulwazi olufanelekileyo, ngolu hlobo lulandelayo:
1. Ulungelelwaniso lwevalve yokhuseleko kufuneka lubonelele: ikopi yelayisenisi yeshishini lomsebenzisi (enetywina elisemthethweni), amandla egqwetha, uhlobo lwevalve yokhuseleko, imodeli yevalve yokhuseleko, isethi yoxinzelelo, njl.
2. Ukulinganisa igeyiji yoxinzelelo kufuneka ibonelele: ikopi yelayisenisi yeshishini lomsebenzisi (enetywina elisemthethweni), amandla ommeli, kunye neeparamitha zokulinganisa uxinzelelo.
Ukuba umenzi ucinga ukuba kunzima ukwenza ulungelelwaniso ngokwakhe, kukho amaziko emarike anokwenza uhlolo egameni lakhe.Kufuneka unikeze kuphela ilayisenisi yeshishini, kwaye unokulinda ngokulula ivalve yokhuseleko kunye nengxelo yokulinganisa igeyiji yoxinzelelo, kwaye akukho mfuneko yokuba uziqhube wedwa.
Ngoko njani ukufumanisa uxinzelelo olupheleleyo lwevalve yokhuseleko?Ngokwamaxwebhu afanelekileyo, uxinzelelo olumiselweyo lwe-valve yokhuseleko luphindaphindwa ngamaxesha e-1.1 uxinzelelo olusebenzayo lwezixhobo (uxinzelelo olumiselweyo akufanele ludlule uxinzelelo loyilo lwezixhobo) ukucacisa ukuchaneka koxinzelelo lwe-valve yokukhusela.
