Umgangatho waseJamani weF4 iValve yeSango eliMfihlo elitywiniweyo

Ngokuqhelekileyo kukho imicu ye-trapezoidal kwintonga yokuphakamisa. Ngokusebenzisa i-nut phezulu kwevalve kunye ne-groove yesikhokelo kumzimba wevalve, intshukumo ejikelezayo iguqulwa ibe yintshukumo yomgca, oko kukuthi, i-torque yokusebenza iguqulwa ibe yi-thrust yokusebenza. Xa uvula i-valve, xa isango lokuphakamisa ukuphakama lilingana no-1: 1 amaxesha ububanzi be-valve, i-flow passage ivuleke ngokupheleleyo, kodwa xa isebenza, esi sikhundla asikwazi ukujongwa. Ekusetyenzisweni okubonakalayo, i-vertex yesikhondo sevalve isetyenziswa njengophawu, oko kukuthi, indawo ekumi kuyo isikhondo sevalve engashukumiyo isetyenziswa njengendawo evulekileyo epheleleyo. Ukuze kuqwalaselwe into yokutshixa yokutshintsha kweqondo lobushushu, ivalve idla ngokuvulelwa kwindawo ye-vertex kwaye iguqulelwe kwi-1/2-1 ukujika njengendawo yevalve evuleke ngokupheleleyo. Ngoko ke, indawo evulekileyo epheleleyo yevalve inqunywe yindawo yesango (okt stroke).

Iimpawu zeMveliso:

1. Isihlalo esine-Flat-bottom, akukho qoqo lokungcola, yenza isitywina sithembeke ngakumbi.

2. Idiskhi yevalve ifakwe kwi-NBR iyonke. Iinxalenye zangaphakathi zevalve zenziwe nge-corrosion-resistant stainless steel kunye ne-alloy yobhedu, engasetyenziselwa inkqubo yogutyulo ukulungelelanisa kwiimeko ezinzima zokusebenza.

3. Ubungakanani obuncinci, ubunzima obulula, kulula ukuyifaka kunye nokugcina

4. Isiqu se-valve sitywinwe ngamakhonkco amathathu e-O, enciphisa kakhulu ukuxhatshazwa kwe-friction yokutshintsha kwaye yenza ukukhanya kokutshintsha kunye nokuqina kwamanzi.
