Zvinofungwa Nezvesimbi yeValve Kubva Mukugadzira Chaiko uye Kushandiswa Kwemunda

Pfupiso yeHunde yeValve

Mukugadzirwa kwemavharuvhu nemamiriro chaiwo ebasa, Hunde yeVharuvhu Kazhinji haisiyo inonyanya kutariswa pakutanga. Zvisinei, kana matambudziko akadai sekushanda nesimba, kufamba kusina kugadzikana, kana kubuda kwemvura nekukurumidza, kuferefeta kunowanzo tungamira kuValve Stem.

Kubva pakuona kwebasa, Valve Stem ine basa rekufambisa kufamba kubva paruoko kana actuator kuenda kuchinhu chekuvharira. Izvi zvinonzwika zviri nyore, asi mukuita, Valve Stem inoshanda pasi pemitoro yakabatana. Inoona torsion panguva yekushanda, axial force kubva pakumanikidzwa, uye stress inodzokororwa kubva pakuvhurwa nekuvhara nguva nenguva.

Mukushandiswa kwemagetsi kana kwemhepo yakawanda, zvinhu izvi zvinova pachena. Valve Stem isina kutwasuka zvakakwana inogona kukonzera kusawirirana panguva yekushanda. Mamiriro asina kunaka epamusoro munzvimbo yekuvharira anowanzo kurumidzisa kupera kwepakeji. Mune zvimwe zviitiko, kutsauka kudiki kwazvo muValve Stem kwakakwana kukanganisa kururama kwenzvimbo, kunyanya kana paine ma actuator emhepo kana emagetsi.

Kusarudzwa Kwezvinhu

Kusarudzwa kwezvinhu ndeimwe nzvimbo inokanganisa zvakananga mashandiro eValve Stem. Pabasa renguva dzose, magadzirirwo eValve Stem esimbi yekabhoni anowanzo shandiswa uye anoshanda zvakanaka. Munzvimbo dzine ngura kana tembiricha yakakwira, sarudzo dzesimbi dzisina ngura dzakadai semartensitic kana precipitation-hardened grades dzinowanzo shandiswa. Mubasa remafuta negasi, sarudzo yezvinhu zveValve Stem inofanirawo kufunga nezvekudzivirira ngura uye kupwanyika kwestress, kwete kusimba chete.

Kubva pamaonero ekugadzira, Valve Stem haisi chikamu chakareruka chinotenderedzwa. Kupera kwenzvimbo yekurongedza, kushanduka kwematanho, uye kugadziriswa kwemucheto zvese zvinopesvedzera mashandiro anoita sisitimu yekuvharira nekufamba kwenguva. Kune mavharuvhu makuru kana magadzirirwo enguva refu, kuchengetedza kubatana uye kutwasuka pamwe chete nehurefu hwese hweValve Stem kwakakosha zvikuru. Kana izvi zvikasadzorwa panguva yekugadzirwa, kuunganidza uye kushanda kwenguva refu zvinogona kukanganiswa.

Sezvo ma actuator achishandiswa zvakanyanya, dhizaini yeValve Stem inofanirawo kutarisisa mwero wepamusoro wekutenderera uye kuramba kuneta. Zvinhu zvakaita sechimiro chekudzivirira kubhururuka, simba remapfudzi rakakwana, uye kubatana kwe actuator kwakavimbika ikozvino ndizvo zvinhu zvakajairika kufunga nezvazvo. Zvinhu izvi zvinowanzo furatirwa, asi zvinokanganisa zvakananga hupenyu hwebasa uye kuchengetedzeka kwekushanda.

Mhedziso

Zvichibva pamhinduro dzemumunda, Valve Stem yakagadzirwa zvakanaka inobatsira kuderedza torque yekushanda, inovandudza kugadzikana kwekuvhara, uye inoderedza nguva yekugadzirisa. Kunyangwe Valve Stem isingabate zvakananga ne process media, ine simba rakananga pakushanda zvakanaka kwevalvu nekufamba kwenguva.
