Iivalve zesango lokutywinwa koxinzelelo zibonakaliswa ngumda ohambahambayo, oshukunyiswa ngokusebenza kwe-stem nut. I wedge ihamba perpendicular ukuya kwicala lokuhamba.
Iivalvu zesango ziyilo lokutywina kabini, ngokuqhelekileyo linoxinzelelo oluncinci lokuhla xa luvuleke ngokupheleleyo, lubonelela ngokuvala okuqinileyo xa luvalwe ngokupheleleyo.
Iivalvu zesango lokutywina zisetyenziselwa inkonzo yoxinzelelo oluphezulu, ngokuqhelekileyo kuxinzelelo olungaphezulu kwe-100 bar. Into ekhethekileyo yebhonethi yokutywina yoxinzelelo kukuba i-body-bonnet joints seal iphucula njengoko uxinzelelo lwangaphakathi ngaphakathi kwevalve lukhula.
Ezona zicelo ziphambili zezi: ishishini lepetrochemical, iisekethe zomphunga, ukujikeleziswa kwebhoyila, ukusetyenziswa kweoyile negesi, izikhululo zamandla.
Iindidi eziqhelekileyo ezisetyenziswayo eziphakathi kokudibana nazo zezi: umphunga, i-condensate, amanzi ebhoyila
Iqondo loxinzelelo oluqhelekileyo lwevalvu ngama-900, 1,500 kunye neekhilogram ezingama-2,500.
Uluhlu loyilo lwevalvu yesango ye-JLPV luloluhlobo lulandelayo:
1.Ubungakanani: 2 "ukuya ku-48" DN50 ukuya kwi-DN1200
2.Uxinzelelo: Udidi lwe-900lb ukuya kwi-2500lb PN160-PN420
I-3.Izinto eziphathekayo: Insimbi yeCarbon kunye nensimbi engenasici kunye nezinye izinto ezikhethekileyo.
I-NACE MR 0175 i-anti-sulfur kunye ne-anti-corrosion metal materials
4.Uqhagamshelo luphela: ASME B 16.5 kubuso obuphakanyisiweyo (RF), ubuso beFlat (FF) kunye noLuhlu lweRingi ngokudibeneyo (RTJ)
ASME B 16.25 kwiziphelo ze-butt welding.
5.Imilinganiselo yobuso ngobuso: ihambelana ne-ASME B 16.10.
6.Ubushushu: -29℃ ukuya ku-580 ℃
Iivalvu ze-JLPV zinokuveliswa kuzo zonke iintlobo zemathiriyeli ukuhlangabezana neemfuno ezahlukeneyo kubathengi, ngakumbi kumgangatho we-NACE.
Iivalvu ze-JLPV zinokuxhotyiswa ngesixhobo somqhubi wegiya, ii-actuator zepneumatic, ii-actuator ze-Hydraulic, ii-actuator zoMbane, ii-bypasses, izixhobo zokutshixa, ama-chainwheels, izikhondo ezandisiweyo kunye nezinye ezininzi ziyafumaneka ukuhlangabezana neemfuno zabathengi.
