Ivalve yokulinganisa Ivalve ye-Hydraulic counterbalance ivalve yesilawuli se-RPEC-LAN

Uhlobo lwevalve yokukhulula

Ngokwesakhiwo esahlukileyo, i-valve yokunceda inokwahlulwa ibe ngamacandelo amabini: uhlobo olusebenzayo oluthe ngqo kunye nohlobo oluphambili. Isivalufa esisebenza ngokuthe ngqo sisivalufa apho uxinzelelo lwehydraulic lomgca we-oyile ophambili osebenza kwi-spool lulungelelaniswa ngokuthe ngqo noxinzelelo olulawula amandla entwasahlobo. Ngokweendlela ezahlukeneyo zesakhiwo se-valve port kunye nomphezulu wokulinganisa uxinzelelo, izakhiwo ezintathu ezisisiseko zenziwe. Kungakhathaliseki ukuba luhlobo luni lwesakhiwo, i-valve yokunceda ngokuthe ngqo iqulethwe ngamacandelo amathathu: uxinzelelo olulawula intwasahlobo kunye nesibambo sokulawula uxinzelelo, i-port yokuphuphuma kunye nomgangatho wokulinganisa uxinzelelo. Ukuthelekisa phakathi kwevalve yokunceda esebenza ngokuthe ngqo kunye nevalve yokunceda ekhokelayo: ivalve esebenza ngokuthe ngqo: Isakhiwo esilula, uvakalelo oluphezulu, kodwa uxinzelelo luchaphazeleka kakhulu kukutshintsha kokuhamba okuphuphumayo, ukuphambuka kokulawulwa koxinzelelo kukhulu, akufanelekile ukusebenza phantsi koxinzelelo oluphezulu kunye noxinzelelo olukhulu. ukuhamba, okuhlala kusetyenziswa njengevalve yokhuseleko okanye kwiimeko apho ukuchaneka kokulawulwa koxinzelelo kungabikho phezulu.

Ivalve yoncedo olulingwayo: Umthombo ongundoqo wevalve usetyenziswa ikakhulu ukoyisa ukukhuhlana kwesiseko sevalvu, kwaye ukuqina kwentwasahlobo kuncinci. Xa utshintsho lwesantya sokuphuphuma lubangela utshintsho oluphambili lwe-valve spring compression, utshintsho lwamandla asentwasahlobo luncinci, ngoko ke utshintsho loxinzelelo lwe-valve luncinci. Ukuchaneka kokulawulwa kwamandla ombane aphezulu, asetyenziswa kakhulu kuxinzelelo oluphezulu, inkqubo enkulu yokuhamba. I-spool ye-valve yokunceda ixhomekeke kwisenzo sokubambisana ngexesha lenkqubo yokuhamba, kwaye isalathiso sokubetha kwiiyure zokuvula nokuvala i-valve ichasene nje, ukwenzela ukuba iimpawu zevalve yokunceda zihluke xa zivulwa. naxa ivaliwe.
