Umvelisi ngamnye weSteam kufuneka axhotyiswe ubuncinci beevalvu ezi-2 zoKhuseleko olunemifuno eyaneleyo. Ivalve yokhuseleko kukuvula kunye nokuvala icandelo elikwimeko evaliweyo evaliweyo phantsi kwesenzo samandla angaphandle. Xa uxinzelelo oluphakathi kwizixhobo okanye umbhobho ophakamayo ngaphezulu kwexabiso elichaziweyo, ivalve egqithayo kwivali ekhethekileyo echaza uxinzelelo lwenkqubo yokuthintela i-Pipeline okanye izixhobo ezivela kwixabiso eliphezulu.
Iivalve zokhuseleko zii-valve ezenzekelayo kwaye zisetyenziswa ikakhulu kwii-boilerators, i-steam verators, iinqanawa zoxinzelelo ukulawula uxinzelelo olungaphezulu kwexabiso elichaziweyo. Njengenxalenye ebalulekileyo yababongisi, iivala zokhuseleko zineemfuno ezingqongqo zofakelo. Oku kukuqinisekisa ukuba isiseko se-steam isiseko sokusebenza kwesiqhelo semveliso.
Ngokwemo yevalve yokhuseleko, yahlulwe yangu-varve of helve enzima, i-Spring-ivali-ivalve ekhuselekileyo kwaye icofe ivalve yokhuseleko. Kwisiseko sokuthobela iimfuno zokufakwa kwe-velip yokhuseleko, nikela ingqalelo kwiinkcukacha ukuthintela iziphumo ezibi kwinkqubo yokusebenza. .
Ekuqaleni,Isikhundla sokufakelwa kwevalve yokhuseleko ngokubanzi ifakwe ngaphezulu kwe-generator ye-Steam, kodwa akufuneki ixhotywe ngemibhobho yokuphuma kunye neevalves zokuthatha i-Steam. Ukuba yivalve ye-over-chenga yokhuseleko, kufuneka ixhotywe ngesixhobo ukuthintela ubunzima ukusuka ngokuhamba ngokwayo kunye nesikhokelo siyekisa ukuphambuka kwe-lever.
Isibini,Inani leeVenkile zokhuseleko ezifakiweyo. Ngeejelerators ze-Steam ezinamachaphaza e-Exvaporation> I-0.5T / h, ubuncinci iivalves ezinokhuseleko kuzo; Ngeemveliso ze-Steam Steators ezinamandla okubanjwa okuphekiweyo Ukongeza, i-varve ye-velomer ye-Steam Venerator inxulumene ngokuthe ngqo nokusebenza kwempumelelo kwe-Steam Venerator. Ukuba uxilongo lomphunga olwenziwe nge-Steam Generator yi-≤3.822MPA, i-orifice yobukhulu kwivali yokhuseleko ayifanele ibe yi- 25mm; Kwaye kwi-Boilers enoxinzelelo lwe-Steam olweleyo> 3.822MPA, i-orifice i-orvemeter yevali yokhuseleko ayifanele ibe yi <20mm.
Ukwengeza,Ivalve ekhuselekileyo ixhotywe ngokubanzi ngombhobho wokuphelisa, kwaye umbhobho wokuphelisa ubhekise kwindawo ekhuselekileyo, ngelixa uphuma kwindawo ekhuselekileyo yokuqinisekisa ukuhamba isitya kwaye udlale i-valve yokhuseleko. Umsebenzi weValve eKeworeyitha ye-Steam Plenerator: Ukuqinisekisa ukuba umvelisi we-Steam akasebenzi kwimeko yokusebenza. Oko kukuthi, ngexesha lokusebenza kwe-Steam Veenerator, ukuba uxinzelelo lungaphezulu koxinzelelo lokusebenza, ivalve yokhuseleko iya kuhamba ukunciphisa umvelisi we-Steam ngokupheliswa. Umsebenzi woxinzelelo othintela i-Steam Pleam Pleerator kunye nezinye iingozi ngenxa yokugqwesa.
I-Nobbeth Steam Pleam isebenzisa i-valve ephezulu ekumgangatho ophezulu enomgangatho ofanelekileyo, uyilo lwesakhiwo sesakhiwo, indawo efanelekileyo yokufaka, umsebenzi ofanelekileyo, kunye nokusebenza ngokungqongqo ngokungqinelana nemigangatho. Ivavanyiwe kaninzi ngaphambi kokuba ahambe umzi-mveliso ukuze aqinisekise ukuba enze into yokhuseleko lomvelisi we-Steam, kuba ngumgca obalulekileyo wokusindisa ubomi kunye nelayini yogcino lobomi ngokhuseleko lobomi.
