I-hydraulic balance valve Excavator i-hydraulic cylinder valve core RVEA-LAN

Isakhiwo esiyisisekelo kanye nesimiso sokusebenza se-valve yokukhulula Kusistimu yokudlulisa amanzi, i-valve ye-hydraulic elawula izinga lokucindezela kwamafutha ibizwa ngokuthi i-valve yokulawula ingcindezi, ebizwa ngokuthi i-valve yokucindezela. Lokho lawa ma-valve afana ngakho ukuthi asebenza ngesimiso sokuthi umfutho we-fluid osebenza ku-spool kanye namandla entwasahlobo ayalingana. Okokuqala, isakhiwo esiyisisekelo kanye nesimiso sokusebenza se-valve yokusiza

Umsebenzi oyinhloko we-valve yokusiza ukunikeza ingcindezi eqhubekayo noma ukuvikelwa kokuphepha kwesistimu ye-hydraulic.

(A) indima kanye nezidingo zokusebenza zevalvu yokusiza

1. Indima ye-valve yokusiza ohlelweni lwe-hydraulic ukuze kugcinwe ukucindezela okuqhubekayo ukusetshenziswa okuyinhloko kwe-valve yokusiza. Ivamise ukusetshenziswa ezinhlelweni zokulawula isivinini sokudonsa, futhi ama-valve okulawula ukugeleza asetshenziselwa ukulungisa ukugeleza ohlelweni, nokugcina ukucindezela kwesistimu ngokuyisisekelo kungashintshi. Ama-valve okusiza okuvikela ukugcwala ngokweqile ngokuvamile abizwa ngokuthi ama-valve okuphepha.

2. Uhlelo lwe-hydraulic lwezidingo zokusebenza kwe-valve yokusiza

(1) Ukunemba kwengcindezi ephezulu

(2) Ukuzwela okukhulu

(3) Umsebenzi kufanele ube bushelelezi futhi ungadlidlizi nomsindo

(4) Lapho ivalvu ivaliwe, uphawu kufanele lube luhle futhi ukuvuza kube kuncane.

(2) Isakhiwo kanye nesimiso sokusebenza se-valve yokusiza

I-valve yokusiza evame ukusetshenziswa ngokuya ngesakhiwo sayo kanye nemodi yesenzo eyisisekelo ingancishiswa ibe uhlobo olusebenzayo oluqondile kanye nohlobo lwesibili lomshayeli.

1. Ivalvu yokusiza ebambayo eqondile Ivalvu yokusiza esebenza ngokuqondile incike kuwoyela ocindezelayo ohlelweni ukuze usebenze ngokuqondile ku-spool futhi ulinganise amandla entwasahlobo ukuze ulawule isenzo sokuvula nokuvala kwe-spool. I-valve yokusiza isebenzisa ukucindezela okulawulwayo njengesignali yokuguqula inani lokucindezela kwentwasahlobo, ngaleyo ndlela iguqule indawo yokugeleza yembobo ye-valve kanye nezinga lokugeleza lokuchichima kwesistimu ukuze kuzuzwe injongo yokucindezela okuqhubekayo. Lapho ingcindezi yesistimu ikhuphuka, i-spool iyakhuphuka, indawo yokugeleza yembobo ye-valve iyanda, izinga lokuchichima liyakhuphuka, futhi ingcindezi yesistimu iyancipha. Umphumela ongemuhle wempendulo owenziwe ibhalansi nokunyakaza kwe-spool ngaphakathi kwe-valve yokusiza kuyisimiso esiyisisekelo sesenzo saso sokucindezela njalo, futhi futhi kuyisimiso esiyisisekelo sokusebenza kwawo wonke ama-valve okucindezela njalo.
