I-YDF-10 hlola i-valve core yesilinda yesisekeli se-excavator

I-valve yendlela eyodwa isho ukuthi uketshezi lungageleza kuphela endaweni yokungena amanzi, kodwa i-medium ephuma emanzini ayikwazi ukuphindela emuva, eyaziwa ngokuthi i-valve yendlela eyodwa.I-valve yokuhlola ibizwa nangokuthi i-valve yokuhlola noma i-valve yokuhlola.Isetshenziswa ohlelweni lwe-hydraulic ukuvimbela ukugeleza okubuyela emuva kokugeleza kwamafutha, noma isetshenziswe ohlelweni lwe-pneumatic ukuvimbela ukugeleza okubuyela emuva komoya ocindezelwe.Kunezinhlobo ezimbili zama-valve okuhlola: uhlobo oluqondile kanye nohlobo lwe-engeli engakwesokudla.Ivalvu yokuhlola eqondile ifakwe epayipini elixhumeke ngentambo.I-valve yendlela eyodwa ye-engeli yesokudla inamafomu amathathu: uxhumano lwentambo, uxhumano lwepuleti kanye nokuxhumeka kwe-flange.

I-valve yokuhlola ibizwa nangokuthi i-valve yokuhlola noma i-valve yokuhlola.Isetshenziswa ohlelweni lwe-hydraulic ukuvimbela ukugeleza okubuyela emuva kokugeleza kwamafutha, noma isetshenziswe ohlelweni lwe-pneumatic ukuvimbela ukugeleza okubuyela emuva komoya ocindezelwe.

Kunezinhlobo ezimbili zama-valve okuhlola: uhlobo oluqondile kanye nohlobo lwe-engeli engakwesokudla.Ivalvu yokuhlola eqondile ifakwe epayipini elixhumeke ngentambo.I-valve yendlela eyodwa ye-engeli yesokudla inamafomu amathathu: uxhumano lwentambo, uxhumano lwepuleti kanye nokuxhumeka kwe-flange.I-hydraulic control valve one-way-way, eyaziwa nangokuthi i-valve yokukhiya noma i-valve yokugcina ingcindezi, iyafana ne-valve yendlela eyodwa ukuvimbela ukugeleza kukawoyela emuva.Kodwa-ke, lapho ukugeleza kwamafutha kudinga ukugeleza ngokuhlehla kumjikelezo we-hydraulic, ukucindezela kwamafutha okulawula kungasetshenziswa ukuvula i-valve yendlela eyodwa, ukuze ukugeleza kukawoyela kugeleze kuzo zombili izinkomba.I-hydraulic control valve yendlela eyodwa isebenzisa i-conical valve core, ngakho inokusebenza okuhle kokuvala.Lapho umjikelezo kawoyela udingeka ukuthi uvalwe, le valve ingasetshenziswa njengendlela eyodwa yokuvala isekethe kawoyela ukuze kugcinwe ingcindezi.Kunezindlela ezimbili zokulawula ukuvuza kwamafutha: ukuvuza kwangaphakathi nokuvuza kwangaphandle.Uhlobo lwangaphakathi lokuvuza lungasetshenziswa kumjikelezo kawoyela ngaphandle kokucindezelwa emuva endaweni ehlehlayo yokugeleza kukawoyela;Uma kungenjalo, uhlobo lokuvuza luyadingeka ukuze kuncishiswe ukucindezela kwamafutha okulawula.
