Ivalve ye-hydraulic valve pilot esebenza ivelufa yokukhulula iBalance slide valve RPGC-LAN

Umahluko weevalvu zokuhamba

Ukwahlula: ivalve ye-throttle, ivalve yokuqukuqela, ivalve yokulawula isantya

I-1) Ngenxa yokuba umsebenzi oyintloko we-valve ye-throttle kunye ne-valve yokulawula isantya kwinkqubo ye-hydraulic kukulungelelanisa ukuhamba kwenkqubo okanye isebe, libizwa ngokuba yi-valve.

2) Ngamanye amaxesha ivalve yokuqukuqela ibhekisa kwivalve yokulawula isantya.

3) Ukusuka kwifomula eyisiseko yokuhamba koxinzelelo, i-valve ye-throttle itshintsha kuphela ubungakanani bendawo yokuhamba kwe-valve port, kunye nesantya esilawulwayo esilawulwayo sikwachaphazeleka ngokutshintsha kwentlupheko yoxinzelelo ngaphambi nangemva kwayo; Ivalve elawula isantya (ngamanye amaxesha ibizwa ngokuthe ngqo yivalve yokuqukuqela) ithatha okanye ilandelelene ivelufa yokunciphisa uxinzelelo, okanye ivalve enxuseneyo eyahlulahlulayo, ngokulandelanayo eyenza ivalve yokulawula isantya seendlela ezimbini (enokuthi iqwalaselwe kuthotho ngaphambi nangemva kwe-actuator, okanye ngokufana phambi kwe-actuator) kunye ne-valve yokulawula isantya seendlela ezintathu (enokuthi idibaniswe kuphela kwichungechunge phambi kwe-actuator, kwaye inokulawula umthwalo kuphela);

I-4) I-valve yokulawula isantya seendlela ezimbini ngokuqhelekileyo isetyenziselwa inkqubo yoxinzelelo olusisigxina, ngenxa yembuyekezo yoxinzelelo lomthwalo, xa uxinzelelo lomthwalo lutshintsha kakhulu, ukuhamba kokulawula ngokusisiseko akuchaphazeleki; Nangona kunjalo, iya kuhlawulela ukusetyenziswa koxinzelelo olugqithisileyo ngendlela yokulahlekelwa koxinzelelo kwi-valve port. Ukuhamba ngokugqithiseleyo kwenkqubo kuphinda kusetyenziswe ngendlela yokufudumala kweoli.

I-5) I-valve yokulawula isantya seendlela ezintathu yinkqubo yokugcina amandla ngenxa yokuba inomsebenzi wokulungelelanisa umthwalo, oko kukuthi, ukunyanzeliswa kokuphuma kwempompo kuphela ixabiso elithile eliphezulu kunomthwalo (3-8bar). Ihlala ixhotyiswe ngevalve yoxinzelelo lomqhubi, ngaphandle kwesinye ivalve yokhuseleko, inokufikelela kukhuseleko lokhuseleko lwenkqubo. Kumashishini omatshini weplastiki, rhoqo ngesiseko sevalve yeendlela ezintathu, ulungelelwaniso lolungelelwaniso lwe-electro-hydraulic proportional pressure pilot valve kunye nevalve yokuqukuqela iqwalaselwe ukuba yenze i-electro-hydraulic proportional pressure flow flow valve composite control valve, ngokuqhelekileyo. eyaziwa ngokuba yi-pq valve, eyenza lula ulwakhiwo kwaye igcine amandla.
