Chii chinonzi SDV Valve?

Mavharuvhu eSDVrudzi rwemidziyo yekuchengetedza inowanzoshandiswa mumaindasitiri emafuta, mishonga, chikafu nedzimwe nzvimbo pamwe nemapuratifomu emafuta ekunze, zita rayo rakazara ndivharuvhu yekudzima, uye zita rechiChinese nderekuti cut off Valve kana kuti Shut off valve. Izvi zvinotevera sumo yakadzama ye SDV valve:

Kuumbwa uye chimiro cheSDV Valves

Vharuvhu yeSDV inonyanya kuumbwa nezvikamu zviviri: actuator nemuviri wevharuvhu. Actuator inosanganisira piston, chitubu neruoko, uye chikamu chinochinja otomatiki. Iactuator yepneumatic yerudzi rwekuvhura mhepo, uye ine solenoid valve yekuvhura kana kuvhara nzira yegesi, iyo inoshandiswa kudzora kuvhurwa kana kuvharwa kwevharuvhu.

Nheyo yekushanda kwevharuvhu yeSDV

Nheyo yekushanda kwevharuvhu yeSDV yakavakirwa pa actuator yepneumatic. Mushure mekugashira mirairo yeFSC system kana emergency shutdown system (ESDV), vharuvhu inovhurwa kana kuvharwa otomatiki nekudzora kuvhurwa kwemhepo yakamanikidzwa kuburikidza nevharuvhu yesolenoid.

Mavharuvhu eSDV Basa uye mashandisirwo

Vharuvhu yeSDV inoita basa rekudzivirira kuvharwa kwemagetsi panguva yekukurumidza musystem, uye inowanzo kuwanikwa papombi yekubuda yemidziyo. Kana mamiriro asina kujairika akaitika, inogona kukurumidza kudimbura denderedzwa remhepo kudzivirira kuti mhepo isarambe ichiyerera, nokudaro ichivimbisa kuchengetedzeka kwesystem.

Mavharuvhu eSDV anoshandiswa zvakanyanya mumapuratifomu emafuta ari kunze kwenyika pamwe chete nemuindasitiri yemafuta ari kunze kwenyika. Pamapuratifomu emafuta ari kunze kwenyika, mavharuvhu makuru eSDV (semuenzaniso, saizi yevharuvhu ≥16 inches, pound class ≥900LB) anowanzo kuwanikwa pakubuda kwepigging ball launcher kana pamusuwo wepigging ball receiver, uye ndiwo michina yekuchengetedza yakakosha mukuita uku.

Hunhu uye zvakanakira

Vharuvhu yeSDV ine hunhu hwekuchengetedza kwakachengeteka, kwakavimbika uye kuri nyore kwemuchina wekufema, kunyanya yakakodzera nzvimbo dzine njodzi.

Mavharuvhu eSDV anongovhurwa zvizere uye akavharwa zvizere, saka anozivikanwawo semavharuvhu ane nzvimbo mbiri. Dhizaini iyi inoita kuti mavharuvhu eSDV ashande zvakanaka kana mvura iri pakati nepakati ichifanira kuchekwa nekukurumidza uye nemazvo.

Kuenda kuSummery

Mavharuvhu eSDVmudziyo unokosha wekuchengetedza unoita basa guru muindasitiri yemafuta, mishonga, chikafu nedzimwe nzvimbo, pamwe chete nemapuratifomu emafuta ari kunze kwenyika. Unoita basa rekuvhura kana kuvhara otomatiki kuburikidza neactuator yepneumatic, une hunhu hwekuchengetedzeka, kuvimbika, kugadzirisa kuri nyore, uye unogona kukurumidza kudzima kufamba kwepakati kana paine dambudziko kuti uve nechokwadi chekuti sisitimu yakachengeteka.
