Valavu yamagetsi yoyang'anira

Valavu ya Stonel Normal Slant: Chipangizo chothandiza kwambiri

Mu njira yowongolera yamadzi oyendetsa mafakitale, njira yeniyeni ya magawo apakatikati monga kuchuluka kwake, kukakamizidwa, ndi kutentha ndikofunikira. Valavu yamagetsi yamagetsi yam'manja ndi imodzi mwazinthu zazikulu zokwaniritsa cholinga ichi. Ndi mapangidwe ake apadera ndi luso labwino kwambiri, imagwira ntchito yosasinthika m'minda yambiri.

Valavu yamagetsi yamagetsi imapangidwa makamaka ndi magawo awiri: wochita zamagetsi komanso thupi lolamulira. Wochita zamagetsi ndi "gwero lamphamvu" lake, lomwe limakonda kugwiritsa ntchito mota ngati gawo loyendetsa. Itha kulandira chizindikiro cha 4-20ME chapano kuchokera ku dongosolo la ulamuliro ndikusintha kukhala makina olinganiza kuti ayendetse valavu ya valavu kuti isunthe. Thupi la valavu limaphatikizapo zigawo monga valavu ya valavu, valavu ya valavu, valavu tsinde, ndi valavu. Pakati pawo, valavu yolimba ndi mpando wa valve amatenga kapangidwe kake. Valavu pachimake ndi wowoneka bwino komanso umapanga bwino kwambiri ndi mpando wa valavu, yomwe ndiye maziko a lamulo lake .

Mfundo yake yogwira ntchito imakhazikitsidwa pa kusintha kwa gap pakati pa valavu yowonera ndi mpando wa Valve. Wochita zamagetsi akalandira chizindikiro chowongolera, chimayendetsa valve kuti uyendetse bwino bwino. Mphamvu ikamapita kumtunda, kusiyana pakati pa valavu ya valavu ndi mpando wa valavu ikuwonjezeka, malo okwera ngati amakula, ndipo kuchuluka kwake kumawonjezeka moyenerera; Valani valavu imasunthira pansi, kusiyana komwe kumatsika, malo oyenda amayamba kuchepera, ndipo kuchuluka kwake kumachepa. Kudzera mu kusintha kosatha kumeneku, valavu yolamulira yamagetsi imatha kuwongolera molondola pang'ono kuti isakwaniritse zofunika pamachitidwe osiyanasiyana. Nthawi yomweyo, chifukwa cha kapangidwe kake katatu, kukhazikika kwa chikhomo pakati pa valavu ya valavu ndiyabwino, yomwe imatha kupewa kudolika kwakanthawi mukatsekedwa .

Valavu yamagetsi yam'madzi yolamulira imakhala ndi zabwino zambiri. Choyamba, ili ndi kuwongolera kwakukulu. Wantchito wake wamagetsi amayankha mwachangu komanso maudindo molondola. Kuphatikizidwa ndi njira yothetsera Valavu Core ndi mpando wa Valve, imatha kuzindikira kuti lamulo labwino lambiri, ndikulondola kulondola ku ± 1%. Ndioyenera nthawi ndi zofunika kwambiri pakuyenda bwino, monga kudyetsa malamulo a materict. Kachiwiri, zimakhala ndi magwiridwe abwino kwambiri. Kapangidwe kake kake kake kamene kamayang'ana pakati pa valavu yolumikizana pakati pa valavu ya valavu ya valavu, zomwe zimapangitsa kusindikiza bwino komanso kutayikira pang'ono. Mulingo wotayira nthawi zambiri umatha kufika a ANSI Class IV kapena kupitilira apo, omwe amatha kupewa kuwonongeka kosafunikira kwa mawonekedwe a sing'anga komanso chilengedwe. Kuphatikiza apo, ili ndi kapangidwe kambiri komanso kakang'ono kakucha, kulemera kwapadera, komanso ndikoyenera kukhazikitsa ndikusunga, makamaka koyenera kwa mapisi ocheperako. Kuphatikiza apo, njira yamagetsi yamagetsi imapangitsa kuti ikhale yosavuta kuphatikiza njira zowongolera zamagetsi, zomwe zimapangitsa kuwongolera kwa mafakitale ndi lamulo chabe, kuchepetsa mphamvu yamathambo, ndikusintha mphamvu .

Pamapulogalamu othandiza, mavesi owongolera a mpando osakhalitsa amagwiritsidwa ntchito kwambiri m'makampani monga petroleum, makampani opanga zamankhwala, metaldurgy, magetsi amagetsi, ndi mankhwala amadzi. Munjira yoyenga, nthawi zambiri amagwiritsidwa ntchito kuwongolera zinyalala za distillation, kuonetsetsa kukhazikika kwa kutentha ndi kukakamizidwa mu nsanjayo ndikusintha mtundu wa nsanja; Pogwiritsa ntchito mankhwala, amatha kuwongolera molondola kuchuluka kwa mankhwala osiyanasiyana amakonzanso chithandizo chomwe chingachitike. M'makonzedwe amagetsi amagetsi, amagwiritsidwa ntchito poyenda mu boiler kudyetsa Madzi amadzi kuti azikhala ndi madzi abwinobwino komanso otulutsa madzi. M'munda wamadzi chithandizo chamadzi, amatha kuwongolera ma desiki a Dosing zida kuti awonetsetse kuti madziwo akukwaniritsa miyezoyo .

Ndi kusintha kosalekeza kwa mphamvu yamafakitale, mavesi owongolera a mpando osakhalitsa amakwiya mosalekeza ndikusintha. Mtundu watsopano wa valavu yamagetsi yoyang'anira magetsi amatenga magetsi apamwamba kwambiri, omwe ali ndi ma typoation apamwamba kwambiri, omwe amatha kuzindikira ntchito monga kutulutsa mawu okha, kukonzanso kudalirika kwa zida. Nthawi yomweyo, malinga ndi kusankha kwa zinthu zakuthupi, valavu yolimba ndi chipinda chovunda, monga stellite, zimawathandiza kuti zitheke kukhala ndi kutentha kwambiri monga kutentha kwambiri, komanso kutupa kwambiri .

Kuti mumve zambiri, ndi magwiridwe ake, zotsatira zabwino kwambiri zokopa, valavu yokhazikika, valavu yosavuta, yamphamvu yamagetsi ikhale zida zofunikira m'munda wamafuta amadzimadzi, ndikutsimikizira bwino zopanga mafakitale othandiza ndi okhazikika.
