I-valve yokulawula ukuhamba kwe-hydraulic, i-valve yokuhlola ye-twin fine throttle

Amavalvu wokulawula ukuhamba, azaziwa nangokuthi amavalvu okunciphisa ukuhamba noma nje amavalvu okuhamba, asetshenziswa ezinhlelweni zamandla amanzi ukuze alawule isivinini sokuhamba kwamanzi (ngokuvamile uwoyela noma igesi) ngaphakathi kwengxenye ethile yesistimu. Ayadingeka ekulawuleni isivinini sama-actuator afana nezilinda namamotho, eqinisekisa ukuthi isistimu isebenza kahle futhi kahle.

Nazi ezinye zezici ezibalulekile zama-valve zokulawula ukuhamba:

1. **Izinhlobo zama-Valve Okulawula Ukuhamba**:
- **Izikhala Ezinqunyiwe**: Lezi zinegama elinqunyiwe lokuvula futhi zifanele izicelo lapho umthamo wokugeleza ungadingi ukulungiswa.
- **Izikhala Ezinokulungiswa**: Lezi zivumela umthamo wokugeleza ohlukahlukene ngokulungisa usayizi wokuvula ngesandla noma nge-actuator.
- **Ukucindezela Okulinganisiwe**: Lezi zivalve zigcina umthamo wokugeleza ongashintshi nakuba kushintsha ucindezelo oluphansi.
- **Okulinganiselwe**: Lezi zivalve zisebenzisa uphawu lwe-elekthronikhi ukuze zilawule kahle umthamo wokugeleza futhi zivame ukusetshenziswa ezinhlelweni zokulawula ezithuthukile.

2. **Ukusebenza**:
- **Ukulinganisa**: I-valve iqukethe i-orifice yokulinganisa noma i-valve spool evimbela ukuhamba, idala ukwehla kwengcindezi phezu kwe-valve.
- **Ukwehla Kocindezelo**: Umthamo wokugeleza ulawulwa ukwehla kocindezelo phezu kwevalve. Ukwehla kocindezelo okuphezulu kuholela kumthamo wokugeleza ophakeme, nokuphambene nalokho.
- **Ukubuyiselwa Kwesimo Sezinga Lokushisa**: Ezinye ama-valve anemisebenzi yokubuyisela izinguquko ekuthambekeni kwamanzi ngenxa yokushintsha kwezinga lokushisa, kugcinwa isivinini sokuhamba esihambisanayo.

3. **Izinhlelo**:
- **Izinhlelo Zokuhambisa**: Ezingxenyeni zokuhambisa, ama-valve okulawula ukuhamba asetshenziswa ukuze alawule ijubane lezi silinda, ama-motors, nezinye izenzo.
- **Izinhlelo Ze-Pneumatic**: Ezingxenyeni ze-pneumatic, ziwulawula ijubane lezinto ezisebenza ngogesi ezifana nezilinda nezinto ezijikayo.
- **Ukulawula Uphethiloli**: Ezikhaleni zemoto, ama-valve okulawula ukuhamba angasetshenziswa ukuze alawule ukuhamba kwephethiloli emshinini.

4. **Izici**:
- **Ububanzi Bokuhamba**: Ububanzi bezinga lokuhamba i-valve engalawula kahle.
- **I-Pressure Rating**: I-maximum pressure differential i-valve engayiphatha ngaphandle kokwehluleka.
- **Uk точность**: Ukunemba okukhombisa ukuthi i-valve ingagcina kanjani ijubane lokuhamba elibekiwe.
- **Isikhathi Sokuphendula**: Ukuthi i-valve ingashintsha kanjani ngokushesha ijubane lokuhamba ukuphendula uphawu lokulawula.

5. **Ukugcinwa**:
- Ukuhlanza njalo nokuhlola ukugqokwa nokulimala kubalulekile ukuze kugcinwe ukunemba nokusebenza kwe-valve zokulawula ukuhamba.
- Ukujwayela okuphindaphindiwe kungase kudingeke, ikakhulukazi ezinhlelweni ezidinga ukunemba okuphezulu.

Ukusetshenziswa okufanele nokunakekela ama-valve okulawula ukuhamba kubalulekile ukuze kusebenze kahle izinhlelo zamandla amanzi. Zisiza ukuqinisekisa ukuthi inani elifanele lamanzi lifika kumadivayisi ngesikhathi esifanele, kuvinjezelwe izinkinga ezifana nokushisa kakhulu, ukulimala okubangelwa isivinini esikhulu, noma ukulahleka kwamandla.

Izivalve zokulawula umthamo zokulawula umthamo futhi ngaleyo ndlela isivinini sama-actuator e-hydraulic (izivalve zokuth throttle nezivalve zokulawula umthamo).
