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>Imiterere nyamukuru, hamwe nibice bya peteroli bigoye bitunganijwe imbere.

* Igenzura rya valve yibanze: Ikintu cyibanze, mubisanzwe slide valve cyangwa rotary valve. Umwanya wacyo ugenzurwa na leveri binyuze mumashanyarazi cyangwa amavuta ya hydraulic yindege, bikagaragaza neza icyerekezo cyumuzenguruko wa peteroli.
* Kurengerwa na valve / umutekano wumutekano: * * Kugabanya umuvuduko ntarengwa wa sisitemu kandi urinda ibice bya hydraulic.
** * Reba valve: * * irinda amavuta gusubira inyuma kandi ikomeza umuvuduko.
** * Gutobora umwobo / umwobo: * * Kugenzura umuvuduko wamavuta kugirango ukore neza kandi bigabanye ingaruka kumasoko yongeye kugaruka. . * sisitemu, igenzura rishobora kubanza kugenzura igipimo gito - cyumuvuduko wikigereranyo, hanyuma nyamukuru nyamukuru ikayoborwa namavuta yindege. Ihame ryakazi: Ntaho ibogamiye (igororotse): Igikoresho cyo kugenzura kiri mumwanya wo hagati, na valve yibanze iri mumwanya utabogamye. Amavuta yumuvuduko ntabwo atemba kuri silinderi ya clutch (clutch ikomeza gusezerana), ntanubwo itemba kuri silinderi ya feri (kurekura feri). Amavuta ava muri pompe yamavuta arashobora gusubizwa mukigega cyangwa kuzenguruka binyuze mumurongo muto - wapakurura umuvuduko (bitewe nigishushanyo). Kuyobora (gukurura inkoni): Iyo umukoresha akurura uruhande rumwe rw'inkoni, intoki ya valve iragenda, ikingura uruziga rw'amavuta kandi ikemerera amavuta y'umuvuduko kwinjira muri silinderi irekura ya clavier ya rulide kuruhande (ibumoso), gusunika piston kugirango uhagarike clutch hanyuma ugabanye imbaraga z'umuhanda wibumoso. Muri icyo gihe kimwe, iki gikorwa gishobora guhuzwa no gufungura urundi ruziga rwamavuta (cyangwa binyuze muburyo bwo guhuza imashini), bigatuma amavuta yumuvuduko yinjira muri silinderi ya feri kuruhande (kuruhande rwibumoso), ugashyiraho feri (mubisanzwe bigira ingaruka mugihe icyuma kigenzura gikururwa mugice cya kabiri, ukagera kumurongo wihuse), kugumana imbaraga kumurongo wiburyo, gusunika imashini kugirango uhindure igitutu cyimbere, gusubizamo amavuta kugirango uhindure icyerekezo cyimbere, gusubizamo amavuta kugirango uhindure ibumoso, gusubizamo amavuta kugirango uhindure ibumoso. silinderi yo gutandukana, hamwe namavuta muri silinderi yo gutandukana asubizwa mumavuta ya peteroli munsi yibikorwa bya clutch reset isoko. Ihuriro ryongeye guhuzwa, kandi amavuta yumuvuduko kuri silinderi ya feri aracibwa (cyangwa umuyoboro wamavuta wo kugaruka urafungura). Feri irekurwa mugikorwa cyo gusubiramo isoko.

Gusaba

Intebe ya valve ikoranya ya bulldozer nikintu cyingenzi cyingenzi cyingenzi kigizwe na buldozer ikurikiranwa, kandi ikoreshwa ryayo rigaragarira mubikorwa bitandukanye bya buldozer:

1. * * Gutwara neza:
2. * Imbaraga zuruhande zisunika inzira yo gutandukana imbere kugirango igere kumurongo mwiza. Birakwiriye guhindura icyerekezo ahantu hafunguye.
3. * Ubwa mbere, hagarika clutch kuruhande, hanyuma ukomeze kuyikurura kugirango ushyire feri kuruhande rumwe. Iyobowe numurongo wimbaraga, inzira yo gufata feri irahagarara, hanyuma imashini yihuta cyangwa mumwanya uhindukirira hagati yumuhanda wa feri. Birakwiye guhinduka cyangwa guhuza neza ahantu hagufi.

4. *
5. *
6 .. Intangiriro yimikorere ikora: * * Ibyiyumvo, ubworoherane, hamwe nukuri kwubuyobozi ahanini biterwa nigishushanyo mbonera cyimiterere ya valve.
* Urufunguzo rwo kwizerwa: * * Kunanirwa kwa sisitemu birashobora gutuma bulldozer itakaza ubuyobozi, bikaba bibi cyane. Gufunga, kwihanganira kwambara, hamwe nubushobozi bwo kurwanya umwanda wa valve ikora ni ngombwa.
* Ingaruka zingirakamaro: Kuyobora neza kandi neza bigabanya gutakaza ingufu no guta igihe.
* Umunaniro wumushoferi: Imiyoborere iremereye, ifatanye, cyangwa ititabiriwe irashobora kongera umutwaro wumushoferi numunaniro.
