Inoshanda kune chiutsi, mhepo uye zvimwe zvepakati midziyo kana pombi (yekushanda tembiricha ≤560 ℃ uye kushanda kumanikidza ≤20MPa) seyakanyanyisa kudzivirira.
- Iine chitubu chakazara-chinoburitsa chimiro dhizaini, vharuvhu ine hombe yekuburitsa coefficient, yakapusa chimiro, yakanaka yekuisa chisimbiso kuita, chaiyo yekuvhura kudzvanywa, kudonha kudiki, kugadzirisa kuri nyore uye humwe hunhu.
- Chigaro chevharuvhu ndicho chigaro cheLaval nozzle valve. Kana ichiyerera nepakati pechigaro chevharuvhu, chiutsi chinosvika pakumhanya kwepamusoro uye hombe yekuburitsa coefficient, inokwanisa kudzikisa huwandu hwekuisa mavharuvhu ekuchengetedza pabhailer. Iine rigid alloy build-up welding, iyo yekuvharisa pamusoro pechigaro chevharuvhu inoratidzira abrasion kuramba, kunyura kwekukura uye hupenyu hurefu hwebasa.
- Iine thermal elastic chimiro, iyo valve disc inoshandisa yayo kushoma deformation yekuripa pasi pepakati acting simba kuvandudza kugona kwekuvharira uye kukunda kumberi kubuda kwevhavhavhavha yekuchengetedza kana kudzvanywa kwepakati kunosvika pakumanikidza. Nehunyanzvi hwekudzimisa tekinoroji, iyo yekuvharisa pamusoro pevhavha disc inovandudza kuomarara, abrasion inodzivirira uye corrosion resistance.
- Mhedzisiro yemhete yekumusoro ndeye kushandura mafambiro epakati kubva pachigaro chevharuvhu kuti uchinje counter-acting simba repakati pavharuvha disc. Chinzvimbo chepamusoro chekugadzirisa mhete chinokanganisa blowdown yevhavha zvakananga.
- Annular space inoumbwa pakati pepamusoro pechindori chekugadzirisa pasi uye ndege yepasi yevhavha disc. Dzvinyiriro inoshandurwa nekudzora vhoriyamu yenzvimbo yeringi yekudzikisa kuti isvike pakuvhurika kwayo.
- Kudzvanywa kwechirimo kunogadziriswa neinoraira nati kuita kuti vharuvhu iwane chaiyo yekumisikidza kudzvanywa zviri nyore uye nekukurumidza.
- Iyo backpressure inogadzirisa sleeve inzira yekubatsira kugadzirisa valve disc backpressure. Kuputika kwakakodzera kunogona kuwanikwa kuburikidza nekugadziriswa kweiyo backpressure kugadzirisa sleeve; gadzirisa kumusoro kuti uderedze backpressure uye gadzirisa pasi kuti uwedzere vharafu backpressure.
- Chibatanidza chekutonhodza chinoiswa pakati pechitubu nemuviri wevharuvhu kudzivirira chitubu kubva pakukanganisa kwekushisa kwakanyanya uye kuve nechokwadi chekugadzikana uye kusimba kwechirimo.
- Chitubu chikamu chakakosha chekutarisa kushanda kwevhavha yekuchengetedza. Zvitubu zvakasiyana zvakagadzirirwa zvakasiyana kumisikidza zvinomanikidza uye blowdowns.
- Iyo inopisa inoparadzanisa inoparadzanisa muviri wevharuvhu kubva muchirimo kuti uderedze kupisa kupisa pachitubu, kuve nechokwadi chekuomarara kwechirimo uye kuita kuti mashandiro echirimo agadzikane.
