Ijeneretha ngayinye ye-steam kufanele ifakwe okungenani ama-valve okuphepha ama-2 ane-displacement eyanele. I-valve yokuphepha iyingxenye yokuvula neyokuvala esesimweni esivame ukuvaleka ngaphansi kwesenzo samandla angaphandle. Lapho ukucindezela okuphakathi kwempahla noma ipayipi ikhuphuka ngaphezu kwenani elishiwo, i-valve yokuphepha idlula I-valve ekhethekile ekhipha i-medium ngaphandle kwesistimu ukuvimbela ukucindezela kwendawo ephakathi kwepayipi noma impahla ukuthi idlule inani elicacisiwe.
Ama-valve okuphepha angama-automatic valves futhi asetshenziswa ikakhulukazi kuma-boilers, amajeneretha e-steam, imikhumbi yokucindezela kanye namapayipi okulawula ukucindezela ukuba kungeqi inani elishiwo. Njengengxenye ebalulekile yama-boilers we-steam, ama-valve okuphepha anezidingo eziqinile zokufakwa. Lokhu futhi ukuqinisekisa ukuthi umusi Isisekelo ukusebenza evamile generator.
Ngokwesakhiwo se-valve yokuphepha, ihlukaniswe nge-valve yokuphepha yesando esindayo, i-spring micro-lift security valve kanye ne-pulse safety valve. Ngesisekelo sokuhambisana nezidingo zokufakwa kwe-valve yokuphepha, qaphela imininingwane ukuze ugweme imiphumela emibi ohlelweni lokusebenza. .
Okokuqala,indawo yokufaka i-valve yokuphepha ngokuvamile ifakwe phezulu kwe-steam generator, kodwa akufanele ifakwe amapayipi okukhipha kanye nama-valve okuthatha umusi. Uma kuyi-valve yokuphepha yohlobo lwe-lever, kufanele ifakwe idivayisi yokuvimbela isisindo ukuthi singahambi ngokwaso kanye nomhlahlandlela wokunciphisa ukuchezuka kwe-lever.
Okwesibili,inani lamavalvu okuphepha afakiwe. Kumajeneretha omusi anamandla okuhwamuka >0.5t/h, okungenani kufanele kufakwe amavalvu okuphepha amabili; kumajeneretha omusi anesilinganiso sokuhwamuka esilinganiselwe ≤0.5t/h, okungenani kufanele kufakwe i-valve yokuphepha eyodwa. Ngaphezu kwalokho, ukucaciswa kwe-valve yokuphepha ye-steam generator kuhlobene ngokuqondile nokusebenza kahle kwe-generator ye-steam. Uma ingcindezi elinganiselwe yesitimu yejeneretha yesitimu ingu-≤3.82MPa, i-orifice diameter yevalvu yokuphepha akufanele ibe ngu-<25mm; futhi kumabhayela anomfutho we-steam olinganiselwe>3.82MPa, i-orifice diameter yevalvu yokuphepha akufanele ibe ngu-<20mm.
Ngaphezu kwalokho,i-valve yokuphepha ngokuvamile ifakwe ipayipi yokukhipha umoya, futhi ipayipi yokukhipha igesi iqondiswe endaweni ephephile, kuyilapho ishiya indawo eyanele enqamula izingxenye ezithile ukuze kuqinisekiswe ukugeleza okushelelayo kwesitimu sokukhipha umoya futhi inikeze ukudlala okuphelele endimeni ye-valve yokuphepha. Umsebenzi we-valve yokuphepha ye-steam generator: ukuqinisekisa ukuthi i-generator ye-steam ayisebenzi esimweni sokucindezela ngokweqile. Okusho ukuthi, ngesikhathi sokusebenza kwejeneretha ye-steam, uma ingcindezi idlula ukucindezela okulinganiselwe kokusebenza, i-valve yokuphepha izohamba ukuze inciphise i-generator ye-steam ngokukhipha umoya. Umsebenzi wokucindezela uvimbela ukuqhuma kwejeneretha ye-steam nezinye izingozi ngenxa yokucindezela ngokweqile.
Amajeneretha omusi we-Nobeth asebenzisa amavalvu okuphepha ekhwalithi ephezulu anekhwalithi ephezulu kakhulu, idizayini yesakhiwo yesayensi, ukufakwa kwendawo okunengqondo, ukwakhiwa okuhle, nokusebenza okuqinile ngokuvumelana nezindinganiso. Ihlolwe izikhathi eziningi ngaphambi kokushiya imboni ukuze kuqinisekiswe isici sokuphepha sejeneretha yesitimu, ngoba iwumugqa obalulekile osindisa ukuphila wejeneretha yesitimu kanye nolayini osindisa ukuphila wokuphepha komuntu siqu.
