Core function: Control the disengagement and engagement of the steering clutch: * * This is its main function. By controlling the flow of hydraulic oil to the steering clutch cylinder, the separation (cutting off the power of the track on that side) or engagement (transmitting power) of one or both clutches can be achieved. Control the application and release of the steering brake: * * When a sharp turn or stationary steering is required, this valve usually interlocks to control the brake on that side (the track side with the clutch disengaged), braking the driving wheel of that side track and causing the machine to rotate around the center of that side track. Implementing "single lever" steering operation: Modern bulldozers typically use a single joystick to control steering. Pull the lever backwards to disengage the clutch (start turning), and continue pulling backwards to apply the brake in conjunction (sharp turn). Release the control lever to automatically reset, clutch engaged, brake released, and resume straight travel. The complex oil circuit design inside the steering valve assembly realizes this operating logic. Structural composition: Valve body>Isakhiwo esiphambili, kunye neepaseji zeoli eziyinkimbinkimbi ezicutshungulwa ngaphakathi.

*Undoqo wevalve yokulawula: Icandelo elingundoqo, elidla ngokuba yivalve yesilayidi okanye ivalve ejikelezayo. Isikhundla salo silawulwa yi-lever yokulawula ngokusebenzisa i-mechanical linkage okanye i-pilot hydraulic oil, ichaza ngokuthe ngqo isalathiso se-oyile.
*Ivalve yokuphuphuma/ivalve yokhuseleko: * * Inciphisa ubuninzi boxinzelelo lwesixokelelwano kwaye ikhusela amacandelo omoya.
** * Khangela ivalve: * * ikhusela umva kweoli kwaye igcina uxinzelelo.
** * Umngxuma wokuthopha/umngxuma wokufuma: * * Lawula isantya sokuhamba kwe-oyile ukuze uqinisekise intshukumo egudileyo yokulawula kunye nokunciphisa impembelelo ekusetweni ngokutsha kwentwasahlobo. : * * Qinisekisa ukuba i-valve core ibuyela ngokuzenzekelayo kwindawo engathathi hlangothi (indawo ethe ngqo ngaphambili) xa i-lever yokulawula ikhululiwe: * * Xhuma i-port yokungena (ukusuka kwimpompo yokulawula), i-port yokubuyisela (i-tank yokubuyisela), izibuko ze-oyile ukuya kwi-cylinders ye-clutch ekhohlo nasekunene, kunye ne-oyile kwi-cylinders ye-brake ekhohlo kunye neyokunene (okanye i-valve yokulawula i-electrolot kwi-interface ye-electrolot {{1}) ulungelelwaniso okanye iinkqubo ezinovakalelo kumthwalo, isithinteli solawulo sinokuqala silawule ivalve ephantsi{2} yovavanyo loxinzelelo, kwaye ke undoqo wevalve uqhutywa yi-oli yokulinga. Umgaqo osebenzayo: Ukungathathi hlangothi (ngokuchanekileyo): I-lever yokulawula iphakathi kwendawo, kwaye i-valve core isendaweni engathathi hlangothi. I-oyile yoxinzelelo ayihambi kwi-cylinder ye-clutch (i-clutch ihlala ibambene), kwaye ayiqhubeki kwi-cylinder ye-brake (ukukhululwa kwe-brake). Ioyile esuka kwimpompo ye-oyile inokubuyiselwa ngqo kwitanki okanye ijikelezwe ngomjelo ophantsi{6}ophantsi woxinzelelo (kuxhomekeke kuyilo). Ukuqhuba (intonga yokutsala): Xa umqhubi edonsa elinye icala lentonga yokulawula, i-valve core ihamba, ivula i-oyile yesiphaluka kwaye ivumele i-oyile yoxinzelelo ukuba ingene kwi-cylinder yokukhulula i-clutch yokulawula ngaphesheya (icala lasekhohlo), ukutyhala ipiston ukuba ikhuphe i-clutch kwaye inqumle amandla omzila osekhohlo. Kwangaxeshanye, esi senzo sinokudityaniswa nokuvula enye isekethe yeoli (okanye ngomatshini wokudibanisa umatshini), ukuvumela ioyile yoxinzelelo ukuba ingene kwi-cylinder yebrake kwelinye icala (icala lasekhohlo), faka i-braking (idla ngokusebenza xa i-lever yokulawula itsalwa kwisiqingatha sesibini, ukuphumeza ujiko olukhawulezayo), gcina amandla kwindlela elungileyo, tyhala umatshini ukujika ngasekhohlo, seta ngokutsha, khulula i-valve yokulawula umva kwindawo ephakathi, inqumle i-oyile yoxinzelelo kwi-cylinder yokwahlula, kunye neoli kwi-cylinder yokwahlula ikhutshwe emva kwitanki yeoli phantsi kwesenzo se-clutch reset spring. I-clutch iphinda idibaniswe, kwaye ioli yoxinzelelo kwi-cylinder ye-brake inqunyulwe (okanye i-oyile yokubuyisela ivuliwe). I-brake ikhululwa phantsi kwesenzo sokusetha kabusha kwentwasahlobo.

Isicelo

Indibano yevalvu yokulawula yebulldozer yinxalenye ebalulekileyo yebulldozer elandelwayo, kwaye ukusetyenziswa kwayo kubonakaliswa ngokuthe ngqo kwimisebenzi eyahlukeneyo yokulawula yebulldozer:

1. * * Ukuqhuba ngokuthe tye: * * Gcina undoqo wevalve kwindawo esembindini, faka iintambo kumacala omabini, khulula iziqhoboshi kumacala omabini, kwaye uqhube iingoma ngokulandelelanayo kumacala omabini.
2. * * Ukujika okugudileyo (ujiko lweradiyasi enkulu): * * Tsala ngobunono icala elinye leleva yokulawula (hayi ngokupheleleyo), khulula kuphela i-clutch kwelinye icala (ngaphandle kokufaka ibreki). Ingoma yecala lamandla ityhala umkhondo wecala lokwahlula phambili ukuze ufezekise ukujika okugudileyo. Ifanelekile ukulungelelanisa ulwalathiso kwiindawo ezivulekileyo.
3. * * Ujiko olutsolo/olumileyo: * * Tsala icala elinye lesixhobo sokuqhuba uye ezantsi. Okokuqala, khulula i-clutch kweli cala, kwaye uqhubeke uyitsala ukuze usebenzise i-brake kwelinye icala ngokudibeneyo. Iqhutywa ngumzila wecala lamandla, indlela yecala lokuqhobosha iyamiswa, kwaye umatshini ngokukhawuleza okanye kwindawo ujika ujikeleze umbindi wendlela yecala lokunyathela. Ilungele ukujika okanye ulungelelwaniso oluchanekileyo kwiindawo ezimxinwa.

4. * * Ukujika kwislope: * * Ukuvula ithambeka kufuna ulawulo oluchanekileyo, kwaye impendulo kunye nokuguda kwevalve yokulawula kubalulekile ukuthintela ukutyibilika okanye ukulahleka kolawulo.
5. * * Ukusebenza okuchanekileyo: * * Kwimisebenzi emihle efana ne-bulldozing kunye nokulinganisa, ukulungiswa rhoqo kwe-angle encinci yokujika kuyafuneka, kunye novelwano kunye nokusebenza kwe-micro motion ye-valve yokuguqula ngokuthe ngqo kuchaphazela umgangatho kunye nokusebenza kakuhle komsebenzi.
6. * * Indawo yokupaka ekhuselekileyo: * * Kwiimeko ezingxamisekileyo, ukutsala zombini iileve zokuqhuba ukuya ezantsi kunokukhawuleza kukhuphe ii-clutches kumacala omabini uze ubambe iibhuleki kumacala omabini, okubangela ukuba ibulldozer ime ngokukhawuleza (kodwa oku akuyondlela yesiqhelo yokuqhobosha, njengoko isiqhoboshi esiphambili ngokuqhelekileyo sinenkqubo eyahlukileyo). Undoqo wokwenziwa komsebenzi: * * Ubuntununtunu, ukuguda, kunye nokuchaneka kokuqhuba kuxhomekeke kuyilo kunye nobume bevalve yokulawula.
*Iqhosha lokuthembeka: * * Ukusilela kwenkqubo yokulawula kunokubangela ukuba ibulldozer iphulukane nolawulo, nto leyo eyingozi kakhulu. Ukutywinwa, ukunganyangeki, kunye nobuchule bokuchasana nokungcoliseka kwevalve yokuqhuba kubalulekile.
*Impembelelo yobuchule: Ulawulo olugudileyo nolusebenzayo lunciphisa ilahleko yamandla kunye nenkcitho yexesha.
*Ukudinwa komqhubi: Ubunzima, ukuxinga, okanye ukungakwazi ukuphendula kunokonyusa umthwalo wokusebenza komqhubi kunye nokudinwa.
