Ivalve yoncedo olulingwayo olusebenzayo Umatshini wokunceda oomatshini iRSDC-LAN

Iivalve zoncedo lokulingwa ziyafumaneka kwiindlela ezahlukeneyo zokucwangcisa.Ivalve yovavanyo yesakhiwo esiqhelekileyo esinamacandelo amathathu, enamacandelo amabini: ivalve yokulinga kunye nevalve engundoqo.

Ivalve yetaper pilot, umngxuma wokudambisa (umngxunya we-throttle osisigxina) kwi-spool yevalve engundoqo kunye noxinzelelo olulawula intwasahlobo kunye zenza umqhubi wesiqingatha sebhulorho yoxinzelelo oluyinxenye yolawulo olungalunganga lwengxelo, enoxanduva lokubonelela ngenqanaba eliphambili lomyalelo woxinzelelo emva kwevalve yokulinga. ulawulo loxinzelelo kwigumbi eliphezulu le-spool yevalve engundoqo.I-spool ephambili ngumthelekisi we-loop yolawulo oluphambili.Ubuso besiphelo esiphezulu busebenza njengomyalelo womyalelo we-spool ephambili, ngelixa ubuso besiphelo esisezantsi busebenza njengomgangatho wokulinganisa uxinzelelo lwelophu ephambili kwaye lusebenza njengamandla empendulo.Umbane obangelwayo unokuqhuba i-spool, ulungelelanise ubungakanani be-port ephuphumayo, kwaye ekugqibeleni ufezekise injongo yokulawula nokulawula uxinzelelo loxinzelelo lwe-inlet P1.

Uhlobo lwe-YF uhlobo olunamacandelo amathathu olululo lwesakhiwo sevalvu yokuphola; 1-(- ivelufa yetaper (ivalve yokulinga); 2 - Isitulo seCone 3 - isigqubuthelo sevalvu; 4 - Umzimba weValve; 5 - umngxuma wokudambisa; 6 - undoqo wevalve; 7 - Engundoqo isihlalo se-8 - i-valve ephambili ye-9 - ukulawulwa koxinzelelo (i-valve ye-pilot) i-10 - ukulungiswa kwe-screws;

Iinzuzo zevalvu yekhatriji yesistim yeHydraulic:

① Akukho mpembelelo yokubuyisela umva ngesantya esiphezulu:

le yeyona nto idla ngokuphathwa yintloko kwiinkqubo zamandla oxinzelelo olukhulu.Ngenxa yokuba i-valve ye-cartridge yi-compact conical valve structure, umthamo wokulawula uncinci xa utshintsha, kwaye akukho "isigqubuthelo esilungileyo" se-valve yesilayidi, ngoko inokutshintshwa ngesantya esiphezulu.Ngokuthatha amanyathelo athile kumacandelo ecandelo lokulinga kunye nokulungelelanisa ulawulo lwesimo sokutshintsha ngexesha lenkqubo yokutshintsha, impembelelo yokubuyisela ingancitshiswa kakhulu ngexesha lokutshintsha.

② Ngokuthembeka kokutshintsha okuphezulu:

i-valve ye-cone jikelele inzima ukwenza isenzo esibi ngenxa yokungcola, ukulahlekelwa kwengcinezelo encinci, ukushisa okuncinci, kunye ne-spool inecandelo elide lesikhokelo, elingelula ukuvelisa i-skew stuck phenomenon, ngoko ke isenzo sinokuthenjwa.

③Ngenxa yokuba i-valve ye-cartridge logic ibekwe emgangathweni ekhaya nakwamanye amazwe, nokuba ngumgangatho wamazwe ngamazwe we-ISO7368, iJamani i-DIN 24342 kunye ne-China (i-GB 2877 standard) ichaze ubungakanani obuqhelekileyo bofakelo behlabathi, obunokwenza ukuba iindawo zekhatriji zabenzi abahlukeneyo zitshintshe, kwaye ayibandakanyi isakhiwo sangaphakathi sevalve.Oku kukwanika umsebenzi woyilo lwevalvu esebenza ngoxinzelelo lwendalo ukushiya umda obanzi wophuhliso.
