I-Residual Pressure Valves (RPV) yinxalenye ebalulekileyo ekukhuseleni iisilinda zegesi ekungcoleni kunye nokuqinisekisa ukusetyenziswa kwazo ngokukhuselekileyo nangokufanelekileyo.Ephuhliswe eJapan kwiminyaka ye-1990 kwaye kamva yaziswa kumgca wemveliso yeCavagna kwi-1996, i-RPVs isebenzisa i-cartridge engaphakathi kwi-cassette ye-RPV ukukhusela ukungcola kunye neengqungquthela zangaphandle ukuba zingene kwi-cylinder.
Ii-RPV zihlelwa njenge-in-line okanye i-off-line, ngokuxhomekeke kwindawo ekuyo ikhasethi ye-RPV ngokunxulumene neziko le-cylinder kunye neziko le-handwheel.I-off-line RPVs zidityaniswe ngasemva kwevalve, ngelixa ii-RPV ezisemgqeni zibeka ikhasethi ye-RPV ngaphakathi kwendawo yokuphuma.
Ii-RPV ziinkqubo ezizenzekelayo eziphendula utshintsho loxinzelelo ngokusebenzisa ingqikelelo yemikhosi echasene nedayamitha ukuvula nokuvala.Xa i-cylinder igcwele, igesi ingena kwikhasethi ye-RPV, apho ivalwe ngetywina phakathi komzimba wevalve kunye ne-O-ring kwikhasethi ye-RPV.Nangona kunjalo, xa amandla abonakaliswe yi-gas pressure kwi-O-ring idlula amandla entwasahlobo kunye nemikhosi yangaphandle, igesi ityhala ikhasethi ye-RPV, icinezela intwasahlobo kwaye ibuyisela umva onke amacandelo e-RPV.Oku kwaphula itywina phakathi kwe-O-ring kunye nomzimba wevalve, okuvumela ukuba igesi ibaleke.
Umsebenzi ophambili wekhasethi ye-RPV kukugcina uxinzelelo ngaphakathi kwi-cylinder ukuthintela ukungcoliseka kwee-agent ze-atmospheric, ukufuma kunye namasuntswana.Xa uxinzelelo lwe-cylinder oluseleyo lungaphantsi kwe-4 bar, i-cartridge ye-RPV ivala ukuhamba kwegesi, ukukhusela inkunkuma yegesi kunye nokuqinisekisa ukuphathwa kwe-cylinder ekhuselekileyo.Ngokusebenzisa ii-RPVs, abasebenzisi be-cylinder yegesi banokugcina indawo yokusebenza ekhuselekileyo nekhuselekileyo ngelixa bekhulisa ukusebenza kakuhle kunye nokuthintela ukungcoliseka.
