I-Hydraulic Flow control valve, i-Twin fine throttle check valve

Amavalvu okulawula ukugeleza, awaziwa nangokuthi izivimbeli zokugeleza noma amavalvu agelezayo nje, asetshenziswa ezinhlelweni zamandla eziwuketshezi ukulawula izinga uketshezi (ngokuvamile uwoyela noma igesi) olugeleza ngalo engxenyeni ethile yesistimu. Zibalulekile ekulawuleni isivinini sama-actuator njengamasilinda namamotho, ukuqinisekisa ukuthi uhlelo lusebenza kahle nangempumelelo.

Nazi ezinye izici ezibalulekile zama-valve okulawula ukugeleza:

1. **Izinhlobo zamavalvu okulawula ukugeleza**:
- **Izindawo Ezigxilile**: Lezi zinokuvuleka kosayizi ongashintshi futhi zifanele izinhlelo zokusebenza lapho izinga lokugeleza lingadingi ukulungiswa.
- **Imikhawulo Eshintshekayo**: Lokhu kuvumela amazinga okugeleza aguquguqukayo ngokulungisa usayizi wokuvula mathupha noma nge-actuator.
- **Ingcindezi Inxeshezelwe**: Lawa mavalvu agcina izinga lokugeleza eliqhubekayo kungakhathaliseki ukuthi kunezinguquko ekucindezelweni komfula.
- **Ngokulinganisa**: Lawa mavalvu asebenzisa isignali kagesi ukuze alawule ngokunembile izinga lokugeleza futhi avame ukusetshenziswa ezinhlelweni zokulawula ezithuthukisiwe.

2. **Ukusebenza**:
- **Ukulinganisa**: Ivalvu iqukethe i-orifice yokulinganisa noma i-valve spool ekhawulela ukugeleza, okwenza umfutho wehle unqamule ivalvu.
- **Ukwehla Kokucindezela**: Izinga lokugeleza lilawulwa ukwehla kokucindezela ku-valve. Ukwehla kwengcindezi ephezulu kubangela izinga lokugeleza eliphakeme, futhi ngokuphambene nalokho.
- **Isinxephezelo Sezinga lokushisa**: Amanye amavalvu anezici zokunxephezela izinguquko ku-viscosity yoketshezi ngenxa yokuhlukahluka kwezinga lokushisa, okugcina izinga lokugeleza elingaguquki.

3. **Izinhlelo zokusebenza**:
- **Ama-Hydraulic Systems**: Kumasekhethi asebenza ngamanzi, amavalvu okulawula ukugeleza asetshenziselwa ukulawula isivinini samasilinda, amamotho, nezinye izixhumi.
- **Amasistimu Womoya**: Kumasekhethi womoya, alawula isivinini samadivayisi asebenza emoyeni njengamasilinda nama-rotary actuators.
- **Ukulawula Uphethiloli**: Ezinhlelweni zezimoto, amavalvu okulawula ukugeleza angasetshenziswa ukulawula ukugeleza kukaphethiloli enjinini.

4. **Izici**:
- **Ibanga Lokugeleza**: Ububanzi bamazinga okugeleza ivalvu engakwazi ukuwalawula ngokuphumelelayo.
- **Isilinganiselwa Sokucindezela**: Umehluko omkhulu wengcindezi i-valve ingakwazi ukuwuphatha ngaphandle kokwehluleka.
- **Ukunemba**: Ukunemba i-valve engagcina ngayo izinga lokugeleza elimisiwe.
- **Isikhathi Sokuphendula**: Ivalvu ingashintsha ngokushesha kangakanani izinga lokugeleza ekuphenduleni isignali yokulawula.

5. **Isondlo**:
- Ukuhlanza njalo nokuhlola ukuguga kubalulekile ukugcina ukunemba nokusebenza kwama-valve okulawula ukugeleza.
- Ukulinganisa ngezikhathi kungase kudingeke, ikakhulukazi ezinhlelweni zokusebenza ezinembayo.

Ukusetshenziswa nokugcinwa ngendlela efanele kwamavalvu okulawula ukugeleza kubalulekile ekusebenzeni kahle kwezinhlelo zamandla oketshezi. Zisiza ukuqinisekisa ukuthi inani elilungile loketshezi lifinyelela kuma-actuator ngesikhathi esifanele, ukuvimbela izinkinga ezifana nokushisa ngokweqile, ukulimala okuvela esivinini esikhulu, noma ukumoshakala kwamandla.

Ama-valve okulawula ukugeleza alawula ukugeleza kanjalo nesivinini sama-hydraulic actuators (ama-throttle valves nama-valve okulawula ukugeleza).
