Ama-valve okulawula aqondisa ukugeleza koketshezi lwe-hydraulic futhi alawule ingcindezi ukuqinisekisa ukusebenza okubushelelezi nokunembile kwamasilinda, ama-motor, nezinye izingxenye ze-hydraulic, njengezinto ezimanzi zokulala phansi kanye nama-tipper ezimotweni zezentengiselwano.
Ungacabanga ngabo njengamaqhawe angaculwanga we-hydraulics yamaloli, asebenza ngemuva ukuze agcine yonke into isebenza njengomshini ogcotshwe kahle. Imiklamo eminingana evamile yokulawula i-valve iphatha izinhlelo zokusebenza ezihlukahlukene ze-hydraulic zamaloli:
- Amavalufu Okulawula Aqondisayo: Lawa mavalvu alawula isiqondiso sokugeleza koketshezi olusebenza ngogesi olunamachweba amaningi kanye nezindawo. Izilungiselelo zisukela ekusebenzeni okulula kokuvula/ukuvala kuya ekulawuleni okulinganayo kokunyakaza okwandayo.
- Amavalvu Okulawula Ingcindezi: Lawa mavalvu alawula ukucindezela kwesistimu, anikeze ukuvikelwa kokucindezela ngokweqile, ukunciphisa ingcindezi, noma ukulandelana kwengcindezi. Amavalvu okusiza asebenza njengamathuluzi okuphepha, anciphisa ukucindezela okukhulu ukuvimbela ukulimala kwengxenye. Ama-valve anciphisayo agcina ingcindezi eqhubekayo eya phansi komfula kungakhathaliseki ukuthi ingcindezi ekhuphukayo iyashintshashintsha. Ama-valve alandelanayo abeka phambili ukugeleza emisebenzini ebalulekile ngaphambi kokuvumela uketshezi kumasekethe esibili.
- Amavalvu Okulawula Ukugeleza: Ukulungisa izinga lokugeleza koketshezi olusebenza ngogesi kuthinta isivinini sama-actuator. Amavalvu okulawula ukugeleza acindezela uketshezi oludlula ukuze alungise isivinini se-actuator ukuze asebenze kahle kakhulu. Ziza ngezinhlobo ezinesinxephezelo sokucindezela ukuze kugcinwe ukugeleza okungaguquki naphezu kwemithwalo ehlukahlukene kanye nezinhlobo ezingakhokhelwa ezishintsha ukugeleza okuhlobene nokuguquguquka kwengcindezi.
Izindlela Zokuvula I-Valve
Amavalvu okulawula angase asebenze ngemva kwezigcawu kodwa futhi ancike ku-opharetha, anezilawuli ezihlukahlukene kuye ngohlobo lwemoto.
- Imanuwali: Amaleveli esandla noma amaphedali ahlinzeka ngokulawula okuqondile komsebenzisi wamavalvu. Ama-valve okwenziwa ngesandla alula futhi anokwethenjelwa kodwa adinga ukufaka njalo komsebenzisi.
- Ukumakhenikha: Amakhamera, ama-plungers, noma amanye amadivaysi emishini avula ngokuzenzakalelayo ama-valve ngokusekelwe ekumeni kwemishini noma ukunyakaza. Ama-valve omshini ahlinzeka ngokusebenza okuzimele ngaphandle kwamandla angaphandle.
- I-Pneumatic: Ama-valve okushintsha komoya acindezelwe, avumela isilawuli somshayeli esikude kusuka kumaswishi asebenza emoyeni noma izinti zokujabula.
- I-Hydraulic: I-Fluid pressure pilots valves spools, evumela isilawuli kude njengezinhlobo zomoya. I-Hydraulic actuation iphatha amandla aphezulu wezinhlelo zokusebenza ezinzima.
- I-Solenoid: Uma inamandla, amakhoyili kagesi ashintsha ama-valve ama-valve, ahlinzeka ngokulawula kukagesi kusuka kumaswishi, ama-relay, noma amamojula okulawula kagesi. Ama-valve e-Solenoid anikeza impendulo esheshayo kanye ne-automation elawulwa yikhompyutha.
Ukulinganisa nokukhethwa
Ama-valve okulawula acaciswe kahle aqinisekisa ukusebenza kahle nokuthembeka. Cabangela lezi zici lapho ulinganisa futhi ukhetha ama-valve:
- Usayizi Wembobo Nomthamo Wokugeleza: Umthamo wokugeleza kwevalvu kufanele ufane nezinga lokugeleza kwesistimu ye-hydraulic ukuze uthole inani eliphakeme lokuphuma kwepompo kanye nezidingo ze-actuator.
- Isilinganiso Sokucindezela: Amavalvu kufanele abe nezilinganiso zokucindezela ezeqa ngokuphephile ukucindezela okukhulu kwesistimu, okuhlanganisa ama-spikes angaba khona.
- Ukucushwa Nokusebenza: Ukucushwa kwe-valve kumele kulethe isilawuli esifiswayo sokuqondisa, ukulawulwa kwengcindezi, noma ukusebenza kokulungiswa kokugeleza.
- Imvelo Nokuhambelana Koketshezi: Izinto ezisetshenziswayo zevalvu kufanele zihambisane nohlobo loketshezi olusebenzisa amanzi asetshenziswayo kanye nanoma yiziphi izici zemvelo, ezifana nokweqisa kwezinga lokushisa noma ukuchayeka kukungcola.
Xhumana nathi noma nini uma udinga usizo lokukhetha ama-valve okulawula afanele.
