Isakhiwo esisisiseko kunye nomgaqo-siseko wokusebenza wevalve yokunceda Kwinkqubo yokuhanjiswa kwe-hydraulic, i-valve ye-hydraulic elawula inqanaba loxinzelelo lwe-oyile ibizwa ngokuba yi-valve yokulawula uxinzelelo, ebizwa ngokuba yi-valve yoxinzelelo. Ziziphi ezi zivalo ezifanayo kukuba zisebenza kumgaqo wokuba uxinzelelo lwe-fluid olusebenza kwi-spool kunye ne-spring force ilinganiswe. Okokuqala, isakhiwo esisisiseko kunye nomgaqo osebenzayo we-valve yokunceda

Umsebenzi oyintloko we-valve yokunceda kukubonelela ngoxinzelelo oluqhubekayo okanye ukhuseleko lokhuseleko lwenkqubo ye-hydraulic.

(A) indima kunye neemfuno zokusebenza kwesivalo soncedo

1. Indima ye-valve yokunceda kwi-hydraulic system ukugcina uxinzelelo oluqhubekayo lusetyenziso oluphambili lwe-valve yokunceda. Ihlala isetyenziselwa kwiinkqubo zokulawula isantya, kwaye iivalve zokulawula ukuhamba zisetyenziselwa ukulungelelanisa ukuhamba kwinkqubo, kwaye ugcine uxinzelelo lwenkqubo ngokusisiseko. Iivalvu zoncedo zokhuseleko lokugcwala zibizwa ngokuba ziivalvu zokhuseleko.

2. Inkqubo ye-hydraulic yeemfuno zokusebenza kwevalvu yokukhulula

(1) Ukuchaneka koxinzelelo oluphezulu

(2) Uvakalelo oluphezulu

(3) Umsebenzi kufuneka ugudiswe kwaye ungangcangcazeli nangxolo

(4) Xa ivalve ivaliwe, itywina kufuneka libe lilungile kwaye ukuvuza kufuneka kube kuncinci.

(2) Ubume kunye nomgaqo wokusebenza wevalve yokunceda

Ivalve yoncedo esetyenziswa ngokuqhelekileyo ngokwesakhiwo sayo kunye nendlela esisiseko yesenzo inokuncitshiswa ukuba ibe kudidi olusebenzayo oluthe ngqo kunye nohlobo lwesibini lokulinga.

1. Ivalve yokunceda esebenza ngokuthe ngqo Ivalve yokunceda esebenza ngokuthe ngqo ixhomekeke kwi-oyile yoxinzelelo kwisistim ukuba isebenze ngokuthe ngqo kwi-spool kwaye ilungelelanise amandla entwasahlobo ukulawula ukuvulwa kunye nokuvala isenzo se-spool. I-valve yokunceda isebenzisa uxinzelelo olulawulwayo njengomqondiso wokutshintsha umlinganiselo wokunyanzeliswa kwentwasahlobo, ngaloo ndlela utshintshe indawo yokuhamba kwe-valve port kunye nesantya sokuphuphuma kwenkqubo ukufezekisa injongo yoxinzelelo oluqhubekayo. Xa uxinzelelo lwenkqubo lukhuphuka, i-spool iphakama, indawo yokuhamba kwe-valve port iyanda, izinga lokunyuka linyuka, kwaye uxinzelelo lwenkqubo luyancipha. Impembelelo yempendulo engalunganga eyenziwa yibhalansi kunye nokuhamba kwe-spool ngaphakathi kwe-valve yokunceda ngumgaqo osisiseko wesenzo sayo soxinzelelo oluqhubekayo, kwaye ikwangumgaqo osisiseko wokusebenza kuzo zonke iivalve zoxinzelelo eziqhubekayo.
