A ivalve yehydraulicNgokwenyani "sisixhobo esinokumelana ne-hydraulic ehlengahlengiswayo", akukho nto ingaphezulu, nangaphantsi. Zonke iivalve ze-hydraulic kufuneka zikwazi "ukulungelelanisa ukuchasana kwe-hydraulic", kwaye zinokwenza oku kuphela, ngaphandle kokukhetha. Ukuqala ukusuka kule nto, kulula kwaye kubanzi ukuqonda iivalve ze-hydraulic, ngakumbi, ezinye iivalve ezidibeneyo kumatshini wokwakha, ezinye iivalve zehydraulic ezinezakhiwo eziyinkimbinkimbi, kwinkqubo ye-hydraulic yangempela, zinokuba neziphumo ezahlukeneyo phantsi kweemeko ezahlukeneyo zokusebenza kunye ne-phenomenon.
Ngophuhliso lobuchwepheshe be-hydraulic namhlanje, uhlobo lweivalve yehydraulic iyakhazimla. Amazwe ahlukeneyo kunye neenkampani ezahlukeneyo kwilizwe elinye zineendidi ezahlukeneyo zeevalvu zehydraulic. Umhleli weli nqaku wenza isishwankathelo esifutshane esisekwe kwiintlobo zeevalvu eziqhelekileyo kwimarike ukuze kubhengezwe:
1. Iivalve zendlela enye zinokwahlulwa zibe ziivalve eziqhelekileyo zendlela enye kunye nehydraulic-controlled one-way-control. Iivalvu eziqhelekileyo zendlela enye zivumela kuphela ukuhamba kolwelo ukuba kudlule kwicala elinye, kwaye ivalve yendlela enye elawulwa ngoxinzelelo lwehydraulic nayo inokuqukuqela ibuyele umva phantsi koxinzelelo lolingo.
2. Ivalve ye-shuttle inokufumana ukuhamba kwamanzi kwimithombo emibini eyahlukeneyo kwaye ihambise uxinzelelo oluphezulu kwindawo enye. Iivalve zeShuttle zihlala zisetyenziswa kwiisekethe zokuva umthwalo kunye neesekethe zeoyile yebrake. Kubandakanya uhlobo lwebhola, uhlobo lwevalve yesitulo kunye nohlobo lwevalve yespool.
3. Ivalve yokuphuphuma kwayo inosetyenziso olwahlukileyo kwizihlandlo ezahlukeneyo. Ngokomzekelo, kwi-quantitative pump throttling speed regulation system, i-valve yokuphuphuma isetyenziselwa ukugcina uxinzelelo lwenkqubo ye-hydraulic (oko kukuthi, uxinzelelo lokuphuma kwepompo ye-hydraulic) rhoqo, kunye nokuphuphuma kokuhamba okugqithisileyo kwepompo ye-hydraulic ibuyele itanki. Ngeli xesha, i-valve yokugqithisa isetyenziselwa uxinzelelo oluqhubekayo. Ukusetyenziswa kwevalvu.
4. I-valve yokunciphisa uxinzelelo yi-valve yokulawula uxinzelelo esebenzisa ukuhamba kwamanzi ukuhamba nge-gap ukuvelisa ukulahleka koxinzelelo, ukwenzela ukuba uxinzelelo lwe-outlet luphantsi kunoxinzelelo lwe-inlet. Ngokweemfuno ezahlukeneyo zohlengahlengiso, i-valve yokunciphisa uxinzelelo ingahlulwa ibe yi-valve yokunciphisa uxinzelelo, i-valve yokunciphisa i-valve esisigxina kunye ne-valve yokunciphisa i-valve.
5. Umsebenzi wevalve yokulandelelana kukusebenzisa uxinzelelo lwe-oyile njengophawu lokulawula ukulawula kunye nokuphuma kwe-oyile yesiphaluka. Inikwe igama ngenxa yokuba isetyenziselwa ukulawula ulandelelwano lwezenzo zee actuators ezininzi. Iivalvu zolandelelwano zohlulwe zibe ziindidi ezisebenza ngokuthe ngqo kunye ne-pilot-operated.
6. Ivalve yokuchasana yenye yezona mveliso zincinci zithembisayo kwishishini le-hydraulic. Abantu abaninzi bathanda ukunyanzela ukhetho lwe-valve yokulinganisa, kwaye ngoko benqaba ukwenza ukhetho.
