Ivalve ye-hydraulic balance valve Ivalve enkulu echasene ne-CXED-XCN yekhatriji

Isakhiwo esisisiseko sevalve yokulawula ukuhamba
Ivalve yokulawula ukuqukuqela yenziwe ikakhulu ngumzimba wevalvu, i-spool, intwasahlobo, isalathisi kunye namanye amalungu. Phakathi kwazo, umzimba wevalve ngumzimba ophambili wevalve yonke, kwaye umngxuma wangaphakathi unikezelwe ukukhokela ulwelo. I-spool ifakwe kumzimba wevalvu kwaye inokushenxiswa ukutshintsha ubungakanani bomngxuma odlulayo, ngaloo ndlela ilawula ukuhamba kolwelo. Imithombo isoloko isetyenziselwa ukubonelela ngohlengahlengiso kunye nembuyekezo yesikhundla se-spool ukugcina izinga lokuhamba elizinzile. Isalathisi sisetyenziselwa ukubonisa umthamo wangoku we-traffic.
Umgaqo-siseko we-proportional solenoid valve

Isekelwe kumgaqo we-valve yokutshintsha kwe-solenoid: xa amandla enqunyulwa, intwasahlobo icinezela intsimbi yentsimbi ngokuthe ngqo kwisihlalo, ukuvala i-valve. Xa ikhoyili inikwe amandla, amandla avela kwi-electromagnetic ayoyisa amandla asentwasahlobo kwaye aphakamise undoqo, ngaloo ndlela avule ivalve. Ivalve ye-solenoid elinganayo yenza utshintsho oluthile kwisakhiwo se-solenoid on-off valve: amandla entwasahlobo kunye ne-electromagnetic force zilungelelaniswa phantsi kwayo nayiphi na i-coil current. Ubungakanani bekhoyili yangoku okanye ubungakanani bamandla e-electromagnetic buya kuchaphazela ukubetha kwe-plunger kunye nokuvulwa kwevalve, kunye nokuvulwa kwevalve (inqanaba lokuhamba) kunye nekhoyili yangoku (uphawu lolawulo) banobudlelwane obufanelekileyo bomgca. . Iivalvu ze-solenoid ezisebenza ngokuthe ngqo zihamba phantsi kwesitulo. Isiphakathi sihamba phantsi kwesihlalo sevalve, kwaye isalathiso saso samandla siyafana namandla ombane we-electromagnetic, kodwa ngokuchaseneyo namandla entwasahlobo. Ngoko ke, kuyimfuneko ukuseta isamba samanani amancinci amancinci ahambelana noluhlu lokusebenza (coil current) kwimeko yokusebenza. Xa umbane ucinyiwe, ivalve ye-Drake liquid proportional solenoid ivaliwe (ngokuqhelekileyo ivaliwe).

Umsebenzi wevalvu ye-solenoid elinganayo

Ukulawulwa kwe-Throttle yesantya sokuhamba kufezekiswa ngokulawulwa kombane (ngokuqinisekileyo, ukulawulwa koxinzelelo kunokufezekiswa ngotshintsho lwesakhiwo, njl.). Kuba ilulawulo lwe-throttle, kufuneka kubekho ilahleko yamandla.
