Yintoni i-SDV Valve?

Iivalvu ze-SDVluhlobo lwezixhobo zokhuseleko ezisetyenziswa kakhulu kwimizi-mveliso ye-petrochemical, yezamayeza, yokutya kunye neminye imimandla kunye namaqonga eoyile aselwandle, igama elipheleleyo nguivalvu yokuvala, kwaye igama lesiTshayina liyi-cut off Valve okanye i-Shut off valve. Oku kulandelayo yintshayelelo eneenkcukacha kwi-SDV valve:

Ukwakhiwa kunye nolwakhiwo lweeValve zeSDV

Ivalvu ye-SDV yenziwe ikakhulu ngamacandelo amabini: i-actuator kunye nomzimba wevalvu. I-actuator iquka i-piston, i-spring kunye ne-hand, kunye nenxalenye yokutshintsha ngokuzenzekelayo. Yi-actuator ye-pneumatic yohlobo lokuvula umoya, kwaye ixhotyiswe nge-solenoid valve ukuvula okanye ukuvala indlela yegesi, esetyenziselwa ukulawula ukuvulwa okanye ukuvalwa kwevalvu.

Umgaqo wokusebenza wevalvu ye-SDV

Umgaqo wokusebenza kwevalvu ye-SDV usekelwe kwi-actuator ye-pneumatic. Emva kokufumana umyalelo wenkqubo ye-FSC okanye inkqubo yokuvala ungxamiseko (ESDV), ivalvu ivulwa okanye ivalwe ngokuzenzekelayo ngokulawula ukuvulwa komthombo womoya ocinezelweyo ngevalvu ye-solenoid.

Umsebenzi kunye nokusetyenziswa kweeValve zeSDV

Ivalvu ye-SDV idlala indima yokukhusela ukuvalwa kwezixhobo xa zingxamisekile, kwaye idla ngokuba kwindawo yokuphuma kwezixhobo. Xa kuvela iimeko ezingaqhelekanga, inokunqumla ngokukhawuleza iluphu yomthombo womoya ukuthintela ukuba i-medium ingaqhubeki nokuhamba, ngaloo ndlela iqinisekisa ukhuseleko lwenkqubo.

Iivalvu ze-SDV zisetyenziswa kakhulu kwiiplatifomu zeoyile zaselwandle kunye nakwishishini le-petrochemical laselwandle. Kwiiplatifomu zeoyile zaselwandle, iivalvu ezinkulu ze-SDV (umz., ubungakanani beevalvu ≥16 intshi, udidi lweepawundi ≥900LB) zihlala zifumaneka ekuphumeni kwesiqalisi sebhola yepigging okanye emnyango wesamkeli sebhola yepigging, kwaye zizixhobo zokhuseleko ezibalulekileyo kule nkqubo.

Iimpawu kunye neenzuzo

Ivalvu ye-SDV ineempawu zokugcinwa okukhuselekileyo, okuthembekileyo nokulula kwe-actuator ye-pneumatic, ngakumbi efanelekileyo kwiindawo eziyingozi.

Iivalvu ze-SDV zivuleka ngokupheleleyo kwaye zivalwe ngokupheleleyo, ngoko ke zaziwa ngokuba ziivalvu ezineendawo ezimbini. Olu yilo lwenza iivalvu ze-SDV zisebenze kakuhle xa umsinga ophakathi kufuneka unqunyulwe ngokukhawuleza nangokuchanekileyo.

Ukuya eSummery

Iivalvu ze-SDVzizixhobo zokhuseleko ezibalulekileyo ezidlala indima ebalulekileyo kumashishini e-petrochemical, amayeza, ukutya kunye namanye amashishini, kunye nakwiiplatifomu zeoyile zaselwandle. Ziyenza isebenze ngokuzenzekelayo ukuvula okanye ukuvala nge-actuator ye-pneumatic, zineempawu zokhuseleko, ukuthembeka, ukulungiswa okulula, kwaye zinokunqumla ngokukhawuleza ukuhamba okuphakathi kwimeko engxamisekileyo ukuqinisekisa ukhuseleko lwenkqubo.
