Iivalve zesango zinokwahlulwa zibe:

1, vula ivalve yesango ngentonga:

Ivalve yesango evulekileyo: I-stem nut ikwisigqubuthelo okanye isibiyeli.Xa uvula kwaye uvala iplate yesango, isiqu sinokuphakanyiswa okanye sithotywe ngokujikeleza i-stem nut.Esi sakhiwo sithandeka kwi-stem lubrication, iqondo lokuvula kunye nokuvala licacile, ngoko lisetyenziswa ngokubanzi.

Ngokwesiqhelo kukho imisonto yetrapezoidal kwintonga yokunyusa, ngenati engaphezulu kwevalve kunye negroove yesikhokelo emzimbeni, intshukumo ejikelezayo isiya kwintshukumo ethe ngqo, oko kukuthi, itorque yokusebenza ingene kwityholo lokusebenza.

Inxalenye yokuvula kunye nokuvala i-valve yesango yiplati yesango, isalathiso sokuhamba kweplate yesango si-perpendicular ukuya kwicala le-fluid, i-valve yesango inokuvulwa ngokupheleleyo kwaye ivalwe, ayinakulungelelaniswa kunye ne-throttled.

2, ivalve yesango ngentonga emnyama:

Ivalve yesango yentonga emnyama ikwabizwa ngokuba yivalve yesango yentonga ejikelezayo (ekwaziwa ngokuba yivalve yesango yentonga emnyama).I-stem nut ikumzimba wevalvu ngokudibana ngokuthe ngqo nophakathi.Ukuvula nokuvala isango, jikelezisa isiqu.

Inxalenye yokuvula kunye nokuvala i-valve yesango elimnyama yi-plate yesango, isalathiso sokuhamba kweplate yesango i-perpendicular ukuya kwicala le-fluid, i-valve yesango inokuvulwa ngokupheleleyo kwaye ivalwe, ayikwazi ukulungiswa kwaye igxininiswe.

I-stem nut ibekwe kwipleyiti yesango, kwaye ivili lesandla liyajika liqhube isiqu ukuze sijikelezise kwaye siphakamise ipleyiti yesango.Ngokuqhelekileyo kukho intambo ye-trapezoidal ezantsi kwesiqu.Ngokusebenzisa intambo ephantsi kwevalve kunye ne-groove yesikhokelo kwi-disc ye-valve, intshukumo ejikelezayo iguqulwa ibe yintshukumo yomgca, oko kukuthi, i-torque yokusebenza iguqulwa ibe yi-thrust yokusebenza.

Umahluko ophambili phakathi kweevalvu zesango ngentonga evulekileyo kunye neevalvu zesango ngentonga ezimnyama zezi zilandelayo:

I-1, isikrufu sokuphakamisa sevalve yesango elimnyama sijikeleza kuphela kwaye akukho ntshukumo yangaphezulu nasezantsi, okuveziweyo yintonga kuphela, i-nut yayo igxininiswe kwipleyiti yesango, ngokujikeleza kwesikrufu ukuphakamisa iplate yesango, apho. asikho isakhelo esibonakalayo;I-screw yokuphakamisa i-valve yesango elivulekileyo ibonakalisiwe, i-nut isondele kwi-handwheel kwaye igxininiswe (akukho jikelezo kwaye akukho ntshukumo ye-axial), isango liphakanyiswa ngokujikeleza isikrufu, isikrufu kunye nesango lijikeleza kuphela. intshukumo kodwa akukho kufuduswa kwe-axial, kwaye imbonakalo sisibiyeli esimilise ucango.

I-2, ivalve yesango elimnyama aliboni isikrufu sokukhokela, kwaye intonga evulekileyo inokubona isikrufu sokukhokela.

3. Ivili lokuqhuba kunye nesiqu sevalve zidityaniswe kunye xa ivalve yesango elimnyama ilayitiwe kwaye icinyiwe.Iqhutywa sisikhondo sevalve sijika kwindawo esisigxina ukuphakamisa idiskhi yevalve phezulu nasezantsi ukugqiba ukuvula nokuvala.Vula iivalvu ze-STEM GATE phakamisa okanye uhlise i-disc NGOKUTHUKUTHELA isikhondo kwivili lokuqhuba.Inqaku elilula kukuba i-valve yesango ye-stem evulekileyo yi-disc edibeneyo kwi-stem ehamba phezulu kwaye ihla kunye, ivili lokuqhuba lihlala ligxininisekile.
