Ivalve yokulinga yivalve encedisayo esetyenziselwa ukulawula indlela yokulawula kwezinye iivalve okanye amacandelo.
Indima yenkqubo ye-hydraulic kukunyusa amandla ngokuguqula uxinzelelo. Inkqubo epheleleyo yehydraulic inamacandelo amahlanu, angala macandelo ombane, amacandelo alawulayo, amacandelo olawulo, amacandelo ancedisayo (izixhobo) kunye neoyile eqhutywa ngamanzi. Iinkqubo ze-hydraulic zinokwahlulwa zibe ngamacandelo amabini: iinkqubo zokuqhuba i-hydraulic kunye ne-hydraulic control systems. Umsebenzi ophambili wenkqubo yokuhanjiswa kwe-hydraulic kukuhambisa amandla kunye nokuhamba. Inkqubo yokulawula i-hydraulic kufuneka yenze imveliso ye-hydraulic system ihlangabezane neemfuno ezithile zokusebenza (ingakumbi ukusebenza okuguquguqukayo). Inkqubo yolwelo lwamanzi idla ngokubhekisa kwisixokelelwano sothumelo lwehydraulic.
Xa unamandla, amandla e-electromagnetic avula umngxuma wokulingwa, uxinzelelo olukwigumbi eliphezulu lehla ngokukhawuleza, kwaye umahluko woxinzelelo oluphezulu wenziwa malunga nelungu elivalayo. Uxinzelelo lwe-fluid lutyhala ilungu elivalayo ukuba liye phezulu kwaye ivalve ivule; xa amandla ecinyiwe, amandla asentwasahlobo avala umngxuma wokulingwa, uxinzelelo lokungena ludlula kumngxuma wokudlula kwaye igumbi likhawuleza lenze umahluko ophantsi nophezulu woxinzelelo olujikeleze ilungu lokuvala ivalve, kwaye uxinzelelo lolwelo lutyhala ilungu elivalayo ukuba liye ezantsi. ukuvala ivalve.
Iimpawu eziqhelekileyo:
I-1) Yenza ibhuloho ye-pilot yokulawula ulwelo kunye nokumelana nolwelo olusisigxina, kwaye ilawula i-valve engundoqo okanye i-valve yesibini okanye i-lever eguquguqukayo ngokuhambelana nomqondiso wegalelo.
I-2) Isantya sokuhamba kwe-valve yenqanaba lokuqala ngokuqhelekileyo kuphela malunga ne-1 litre / min, kwaye ubuninzi buzi-3 ilitha / min. Isantya sokuhamba kwevalve yokulinga yesibini kufuneka imiselwe ngokweemfuno zokwenyani.
3)Isiginali yegalelo incinci.
4) Inokwamkela iindlela ezahlukeneyo zokufaka, ezifana ne-manual, umbane, i-hydraulic, i-pneumatic, i-mechanical cam, umlinganiselo wombane, njl.
I-5) Kwimeko yolawulo lwempompo eguquguqukayo, iindidi ze-valve zomqhubi zenza isakhiwo semodyuli, okwenza kube lula ukukhetha phakathi kwemisebenzi emininzi.
I-6) Ivalve yokulinga ngokwayo idla ngokuba yivalve yokulawula ubungakanani obuncinci, ubukhulu becala ivalve yokulawula uxinzelelo.
Umgaqo wokusebenza:
Xa usebenza, uxinzelelo lwe-hydraulic lusebenza kumphezulu wokulinganisa uxinzelelo lwe-spool ephambili kunye ne-pilot spool ngexesha elinye. Xa ivalve yokulinga ingavulwanga, ioyile ayiqukuqeleli kwindawo yevalve, kwaye uxinzelelo olusebenza kwi-spool ephambili kumkhombandlela ongasentla nasezantsi uyalingana, kodwa ngenxa yokuba indawo yoxinzelelo olusebenzayo kwindawo ephezulu yesiphelo inkulu. kunommandla woxinzelelo osebenzayo womgangatho osezantsi wesiphelo, i-spool ephambili ikwisiphumo samandla Ngaphantsi kwesenzo, sikwindawo esezantsi, kwaye i-valve port ivaliwe. Xa umfutho we-oyile ongenisa i-oyile unyuka ukwenza ivelufa yokulinga ivuleke, ulwelo lubuyela emva kwitanki nge-orifice ekwispool engundoqo kunye nevalve yokulinga. Ngenxa yempembelelo yokudambisa i-orifice, uxinzelelo lwe-hydraulic kwiindawo eziphezulu kunye nezisezantsi ze-spool eziphambili azilingani. I-spool ephambili ihambela phezulu phantsi kwesenzo somohluko woxinzelelo ukuvula i-valve port ukufezekisa ukuphuphuma kunye nokugcina uxinzelelo oluzinzile. Uxinzelelo oluphuphumayo lunokulungelelaniswa ngokulungelelanisa intwasahlobo elawula uxinzelelo lwevalve yokulinga.
