Intshayelelo yeValve yeButterfly

Intshayelelo:

Ivalvu yebhabhathaneivela kusapho lweevalvu ezibizwa ngokubaiivalvu zokujika ikota. Xa isebenza, ivalvu ivuleka ngokupheleleyo okanye ivaliwe xa idiski ijikeleziswa ngekota. "Ibhabhathane" yidiski yesinyithi efakwe kwinduku. Xa ivalvu ivaliwe, idiski ijikeleziswa ukuze ivale ngokupheleleyo indlela. Xa ivalvu ivuliwe ngokupheleleyo, idiski ijikeleziswa ngekota ukuze ivumele indlela engathintelwanga yolwelo. Ivalvu inokuvulwa kancinci kancinci ukuze ithontsize i-throttle.

Kukho iintlobo ezahlukeneyo zeevalvu zebhabhathane, nganye ilungele uxinzelelo olwahlukeneyo kunye nokusetyenziswa okwahlukileyo. Ivalvu yebhabhathane ye-zero-offset, esebenzisa ukuguquguquka kwerabha, inezinga eliphantsi loxinzelelo. Ivalvu yebhabhathane ye-double offset esebenza kakhulu, esetyenziswa kwiinkqubo zoxinzelelo oluphezulu kancinci, isuswa kumgca ophakathi wesihlalo sediski kunye nesitywino somzimba (i-offset yokuqala), kunye nomgca ophakathi webhore (i-offset yesibini). Oku kudala isenzo sekhamera ngexesha lokusebenza ukuphakamisa isihlalo siphume kwisitywino okubangela ukungqubana okuncinci kunokuba kudalwe kuyilo lwe-zero offset kwaye kunciphisa ukuthambekela kwayo kokuguguleka. Ivalvu efanelekileyo kakhulu kwiinkqubo zoxinzelelo oluphezulu yivalvu yebhabhathane ye-triple offset. Kule valve i-axis yoqhagamshelwano lwesihlalo sediski iyasuswa, esebenza ukuphelisa unxibelelwano olutyibilikayo phakathi kwediski kunye nesihlalo. Kwimeko yeevalvu ze-triple offset, isihlalo senziwe ngentsimbi ukuze sikwazi ukwenziwa ngomatshini ukuze sivale i-bubble tight xa sidibana nediski.

Iintlobo

1. Iivalvu zebhabhathane eziqinileyo– olu hlobo lwevalvu lunesihlalo serabha esiqinileyo esinediski yesinyithi.
2. Iivalvu zebhabhathane ezinemibala emibini(iivalvu zebhabhathane ezisebenza kakuhle okanye iivalvu zebhabhathane ezisebenza kabini) – iintlobo ezahlukeneyo zezixhobo zisetyenziselwa isihlalo kunye neediski.
3. Iivalvu zebhabhathane ezi-Triply-eccentric(iivalvu zebhabhathane ezi-triple-offset) – izihlalo zenziwe nge-laminated okanye nge-solid metal seat design.

Iivalvu zebhabhathane zesitayile se-wafer

Iivalvu yebhabhathane yesitayile se-waferYenzelwe ukugcina isitywino esichasene nomahluko woxinzelelo oluya kwicala elinye ukuthintela nakuphi na ukubuyela umva kwiinkqubo ezenzelwe ukuhamba kwelinye icala. Ikwenza oku ngesitywino esiqinileyo; oko kukuthi, i-gasket, i-o-ring, i-precision machined, kunye nobuso bevalvu ethe tyaba kumacala aphezulu nasezantsi evalvu.

Ivalvu yebhabhathane efana neLug

Iivalvu zesitayile seLugzinezifakelo ezinemisonto kumacala omabini omzimba wevalvu. Oku kuvumela ukuba zifakwe kwinkqubo kusetyenziswa iiseti ezimbini zeebholiti kwaye zingabi namantongomane. Ivalvu ifakwe phakathi kweeflange ezimbini kusetyenziswa iseti eyahlukileyo yeebholiti kwiflange nganye. Olu seto luvumela ukuba icala ngalinye lenkqubo yepayipi liqhawuke ngaphandle kokuphazamisa elinye icala.

Ivalvu yebhabhathane efana ne-lug esetyenziswa kwinkonzo ye-dead end idla ngokuba nomlinganiselo woxinzelelo ophantsi. Umzekelo, ivalvu yebhabhathane efana ne-lug efakwe phakathi kweeflange ezimbini inomlinganiselo woxinzelelo we-1,000 kPa (150 psi). Ivalvu efanayo efakwe kwiflange enye, kwinkonzo ye-dead end, inomlinganiselo we-520 kPa (75 psi). Iivalvu ezifakwe kwi-lug ziyamelana kakhulu neekhemikhali kunye nezinyibilikisi kwaye zinokuphatha amaqondo obushushu afikelela kwi-200 °C, nto leyo eyenza ukuba ibe sisisombululo esisebenzisekayo.

Ukusetyenziswa kushishino

Kwimizi-mveliso yamayeza, iikhemikhali, kunye nokutya, ivalvu yebhabhathane isetyenziselwa ukuphazamisa ukuhamba kwemveliso (eqinileyo, elulwelo, igesi) ngaphakathi kwenkqubo. Iivalvu ezisetyenziswa kwezi mizi-mveliso zihlala zenziwe ngokwezikhokelo ze-cGMP (indlela yokuvelisa elungileyo yangoku). Iivalvu zebhabhathane zihlala zithatha indawo yeevalvu zebhola kumashishini amaninzi, ngakumbi ipetroliyam, ngenxa yeendleko eziphantsi kunye nokulula kokufakwa, kodwa imibhobho eneevalvu zebhabhathane ayinakuxutywa ukuze icocwe.
