Isilawuli esilingwayo se-RPGE-LAN ​​Ivalve enkulu yokulinganisa ukuhamba

     Umgaqo osebenzayo wevalve yokuhamba

I-valve ejikelezayo luhlobo lwezixhobo zokulawula ukulawula ukuhamba kwamanzi, umgaqo wayo wokusebenza kukulungelelanisa ubungakanani bokuhamba ngokutshintsha indawo yokuhamba kombhobho. Ivalve yokuqukuqela isetyenziswa kakhulu kwinkqubo yokuhanjiswa kwehydraulic kwaye idlala indima ebaluleke kakhulu. Amacandelo aphambili evalve yokuqukuqela aquka umzimba wevalvu, izinto ezilawulayo (ezifana nespool, idiskhi yevalve, njl. njl.) kunye ne-actuator (efana ne-electromagnet, i-hydraulic motor, njl.). Iindidi ezahlukeneyo zeevalve zokuhamba zikwahluke kwisakhiwo, kodwa umgaqo wabo wokusebenza uyafana.
Umgaqo osebenzayo we-valve yokuhamba unokwahlulwa ngokulula kwiinkqubo ezimbini: ukutshintshwa kwendawo yokulawula kunye nokuhamba kwe-spool / disc.

Okokuqala, xa i-liquid idlula emzimbeni wevalve yokuhamba, idibana nento elawulayo. Ezi zinto zokulawula zinendawo ethile kumzimba wevalve, kwaye indawo yokuhamba kwamanzi inokutshintshwa ngokulungelelanisa indawo yabo. Ngale ndlela, ukuhamba kolwelo kunokulawulwa. Iimpawu zokulawula eziqhelekileyo ziyi-spool kunye nediski.

Okwesibini, ivalve yokuqukuqela nayo ine-spool okanye i-disc mechanism, intshukumo yayo itshintsha ukuhamba kolwelo kumzimba wevalvu. Umzekelo, xa i-electromagnetic ivuliwe, i-spool iya kunyuswa okanye ihle phantsi ngamandla kazibuthe. Esi senzo sitshintsha indawo yento elawulayo, ethi yona ilawule ukuhamba kolwelo. Ngokufanayo, xa i-hydraulic motor iqhuba i-valve disc ukuba ijikeleze, iya kutshintsha kwakhona indawo yokuhamba kwamanzi, ngaloo ndlela ilawula izinga lokuhamba.
