Isu tiri nhamba yekutanga mubhokisi rako rekunyora uye tinopa nhau dzakanyanya kukosha muindastiri-ichiita kuti uve nehungwaru uye uwedzere kufambira mberi mumusika uyu unogara uchichinja wemakwikwi. Isu tiri nhamba yekutanga mubhokisi rako rekunyora uye tinopa nhau dzakanyanya kukosha muindastiri-ichiita kuti uve nehungwaru uye uwedzere kufambira mberi mumusika uyu unogara uchichinja wemakwikwi. Iwo mavharuvhu akakodzera, pombi uye fittings zvakakosha pakushanda kwakabudirira kwemidziyo yekugadzira magetsi. Midziyo iyi inosanganisira zvigadzirwa zvine magadzirirwo akasiyana-siyana anogona kumisikidza nzira dzekubatanidza uye yekuisa chisimbiso, uye kuve nehukama huri nani hwekubatanidza, nekudaro kuve nechokwadi chekushanda kwakachengeteka mumagetsi anopisa, enyukireya uye anovandudzwa simba remagetsi. Mugadziri anoratidza kuti kana achisimudzira zvigadzirwa zvayo, mari yekuisa yakaderera, kuchengetedzwa uye kushanda zvakanaka kunovandudzwa, uye kurongwa uye kusarongeka kwekugadzirisa kunonoka kunoderedzwa. Heano vamwe vanotungamira vanogadzira uye makambani ebasa emagetsi emagetsi mavharuvhu, pombi uye mafittings. Boldrocchi yakapedza kuedza kwakabudirira kwe7m ne7m diverter valve yemagetsi egasi kutanga kwegore rino. Iyo diverter vharafu ivharuvhu yenzira nhatu inokwanisa kuburitsa gasi returbine yekuburitsa gasi kumhepo kuburikidza nechimney chekunzvenga, kana mukati mekupisa kudzoreredza chiutsi jenareta. Iyo damper ine hukuru hwepamusoro uye inodarika mwero maererano nekuisa chisimbiso chejometri, chisimbiso chekuisa chisimbiso uye nguva yekuvhara, uku ichideredza kugadzirisa uye kurerutsa kufambisa uye kusangana. Iyi diverter nyowani inobvumirawo kukurumidza shanduko kubva kune imwechete kutenderera system kuenda kune yakasanganiswa kutenderera system. Yakagadzirirwa kutsungirira tembiricha inosvika 700C (1,300F), vibration uye gasi kusagadzikana, uye kunatsiridza mapfekero echikamu. Iyo diverter inoshongedzerwa nemhepo yekuisa chisimbiso system, iyo inogona kuita yekuisa chisimbiso dhigirii rekubuda gasi rakaenzana ne100% (kuzara chisimbiso). Mhepo yekusimbisa chisimbiso yakakura kupfuura +500 mm yembiru yemvura (mm wc), uye mugadziri wemidziyo yepakutanga anowanzoda +50 mm wc. Iyo shunt ine hydraulic actuator. Zvinoenderana nezvinodiwa nevatengi, nguva yayo yakajairika yekushanda isingasviki 60 masekonzi, uye nguva yekumisa yekukurumidzira isingasviki 20 seconds. Nekudaro, iyo shunt yakagadzirwa uye inogadzirwa kupfupisa nguva yekutyaira. Boldrocchi yakagadzira iyo splitter kuti ive nyore kutakura uye kuunganidza. Iyo splitter inogona kufanounganidzwa kuita zvidimbu zvinoverengeka, kana inogona kuunganidzwa zvizere uye kuendeswa (chikamu chimwe). Boldrocchi yakagadzira iyo splitter kuti igadzirwe nyore nyore pasi pechimuni-chekutenderera chekuburitsa pachinzvimbo chegokora riripo. Boldrocchi, Biassono, Italy Spirax Sarco Engineering Co., Ltd. inopa zvigadzirwa uye masevhisi ekugadzirisa kwesimba rinopisa. Yayo Spira-trol modular control valve yakaiswa mukushandiswa kufekitori, ichibvumira nekukurumidza "plug uye kutamba" kuisirwa. Spira-trol's modular dhizaini ine kukurumidza-kuchinja "clamp-in-place" chigaro chevharuvhu, zvinoreva kuti basa rayo rinogona kushandurwa kuti rienderane nekuchinja mamiriro echirimwa pasina kutsiva vharafu rese. Iyo yekuzvigadzirisa in-situ clamping valve chigaro zvakare inorerutsa kugadzirisa, saka hapana yakakosha maturusi anodiwa, uye hapana chikonzero chekubvisa vharafu kubva papombi. Izvi zvinogona kuchengetedza mari yakawanda kana ichienzaniswa neyechinyakare magadzirirwo anowanzo ane yakagadziriswa screw-in valve seat. Iyo screw-in valve seat inowanzonamira panzvimbo, ichida kuti vharafu iparadzwe, zvichikonzera kureba kwechirimwa. Ipa 1/2 inch kusvika 4 inch yemagetsi uye pneumatic Spira-trol valve, kusvika kuANSI 150 flange shanduro. Iine yakazara Spira-trol chigadzirwa akatevedzana (inokwidziridzwa kusvika 8 inches) uye ANSI 600 kudzvanywa renji, Spirax Sarco inogona kupa kudzora mhinduro kubva pakudziya, kufefetedza uye mhepo yekumisikidza kugadzirisa uye simba kune inoda masevhisi ekushandisa. Spirax Sarco, Cheltenham, UK Clark Valve Kambani yakazivisa kuti dhizaini yegedhi revharuvhu yakagamuchira API 641 certification, inova yekutanga yekudzora vharafu kugamuchira iyi yakaderera emission performance certification. Iyo API 641 yakajairwa inoshanda kune ese mavharuvhu stem sealing materials, uye yakanyanya kuomesesa inobvumidzwa kuvuza izvikamu zana pamiriyoni nehuwandu (ppmv). Iyi API yekuyedza chiyero inoda kuti vharafu itore mazana matanhatu negumi madhigirii pasi pekunyanya kupisa tembiricha kuti iongorore mashandiro ekubudisa panguva yekukurumidza kutenderera kwehupenyu. Kubuda kwehupoteri kubva kumagadzirirwo evharuvhu echinyakare muzvivakwa zveindasitiri ndiyo honzeri huru yekusvibiswa kwemhepo, uye iyo yakasarudzika dhizaini yemavharuvhu emagedhi inopa chisimbiso chakanakisa pahunde yevharuvhu, nekudaro ichideredza kuburitswa uku. Iyo patent yevhavha yevhavha yakayedzwa yakazvimirira neYarmouth Research uye Technology. Iyo valve yakaratidza kuti vheji yakapfuura bvunzo yekuvuza isingasviki makumi maviri ppmv, pazasi peiyo 100 ppmv muganho. Iyo yakasarudzika dhizaini yevhavhavhavha yevhavha yakatove yakanakisa dhizaini yekudzora mashandiro munyika, uye iko zvino ndiyo yakanyanya kusarudzika vharuvhu yekudzora zvachose. Clarke Valve, Miami, Florida Westinghouse yakaparura zvisimbiso zvayo zveSigma Reactor Coolant Pump (RCP), zvakagadzirirwa kuti zvibatanidzwe seWestinghouse RCP yechizvarwa chekutanga chisimbiso chinotsiva zvikamu uye zvemaindasitiri. Inovavarira kupa sevhisi yakavimbika kweanosvika makore gumi nemaviri, ayo anogona kuchengetedza mutengo, kuderedza madosi uye kugadzirisa njodzi yezvidyarwa zvemagetsi enyukireya. Zvisimbiso zveSigma zvakagadziridzwa kuti zvikwanise kufungidzira kuita uye kuderedza kunzwisiswa kwezvakatipoteredza, uye zvinotsigirwa neanopfuura maawa e20,000 ekusimudzira uye bvunzo dzekufanirwa. Sigma zvisimbiso zvinonyatsoenderana neWestinghouse SHIELD passive thermal shutdown seals.
