Iimpawu zokuhamba komgaqo-nkquboivalvuikakhulu ziintlobo ezine zeempawu zokuhamba kwamanzi ezifana nokuvula ngokukhawuleza kwepesenti ethe tye kunye neparabola. Xa ifakelwe kwinkqubo yokulawula yokwenyani, uxinzelelo olwahlukileyo lweivalvuiya kutshintsha ngotshintsho lokuhamba, oko kukuthi, ukulahleka koxinzelelo lwenxalenye yepayipi kuya kuba ncinci xa ukuhamba kuncinci, uxinzelelo olwahlukileyo lweivalvuiya kuba nkulu, kwaye uxinzelelo olwahlukileyo lweivalvuiya kuba ncinci xa umsinga umkhulu Oku kwahlukile kwiimpawu ezisisiseko zeivalvuuphawu olubizwa ngokuba luphawu lokuhamba okusebenzayo kokuqalisa ngokukhawuleza uphawu lwevalvu yangaphakathi lumile okwediski, olusetyenziswa kakhulu ekuvuleni nasekuvaleni.
Ukulawula imo yomphezulu we-valve spool
Iimpawu zolawulo lokuhamba kwamanziivalvuzimiselwa kukudityaniswa kweempawu zokuhamba kwamanziivalvukunye nepompo yepayipi yenkqubo, njl. Ngokwesilinganiselo seivalvuUkulahleka koxinzelelo kwinto nganye yolawulo kunye nenkqubo, umlinganiselo wokulahleka koxinzelelo lwevalvu kwinkqubo yento yolawulo ukhethwe kwitheyibhile elandelayo Iimpawu zokuhamba kwevalvu Ulawulo lokuhamba okanye ulawulo lwenqanaba lolwelo ngaphantsi kwe-40% Ulawulo lokuhamba okanye ulawulo lwenqanaba lolwelo ngaphezulu kwe-40% ulawulo loxinzelelo okanye ulawulo lobushushu ngaphantsi kwe-50% ulawulo loxinzelelo okanye ulawulo lobushushu ngaphezulu kwe-50% Umgca kuba ukulahleka koxinzelelo lombhobho kuhambelana nesikwere sesantya sokuhamba kuyanda, ukuba iimpawu zomzimba wevalvu ziinguqu ezilula zomgca, uxinzelelo olwahlukileyo lwevalvu luyanda xa ukuhamba kuncinci, ukuhamba kwevalvu kuya kuba kukhulu kakhulu, umahluko woxinzelelo lwevalvu uyancipha xa ukuhamba kukhulu, kwaye ukuhamba akunakulingana nokuvulwa kwevalvu. Kule njongo, ukongeza iimpawu zombhobho kunye nepompo ukufezekisa ulawulo lokuhamba oluzimeleyo kubungakanani bokuhamba kwaye kuphela ngokulingana nokuvulwa kwevalvu yinjongo yoyilo lweempawu ezilinganayo zepesenti.
Inkqubo yepayipi kunye nokulahleka koxinzelelo
Isenzo sevalvu yokulawula sinokukhethwa ngokuhambelana nomxube wesixhobo sokuqhuba kunye nomzimba wevalvu.
Ukudibanisa umzimba we-drive kunye ne-valve kunye nokusebenza kwe-valve (umzekelo we-valve yesihlalo esinye)
Isenzo sevalvu siquka isenzo esihle isenzo esibuyela umva uhlobo lwesenzo isenzo iindlela ezi-3 uhlobo lwediaphragm kunye nohlobo lwesilinda i-pneumatic drive isenzo esihle singokwanda kwesignali yoxinzelelo UKUVALA indlela yevalvu, eyaziwa ngokuba yi-AIR TO CLOSE isenzo esibuyela umva singokwanda kwesignali yoxinzelelo UKUVULA indlela yevalvu, eyaziwa ngokuba yi-AIR ukuvula okanye Isignali yokusebenza kombane ingaguqulwa ibe yisignali yomoya nge-locator. Xa isignali yokusebenza imisiwe okanye umthombo womoya uphazamisekile kwaye umbane ucinyiwe, nceda ukhethe ivalvu YOKUVALA okanye uvule ucinga ngengqiqo yokhuseleko lwenkqubo.
Umzekelo, xa kulawulwa ubungakanani be-asidi ngokusebenzisaivalvukwinkqubo yokuxuba amanzi kunye ne-asidi, kukhuselekile kwaye kufanelekile ukuvala ulawulo lwe-asidiivalvuxa umgca wesignali yombane wophukile okanye imibhobho yesignali yomoya ivuza kwaye umthombo womoya uphazamisekile kwaye umbane ucinyiwe. Kufuneka kusetyenziswe ivalvu yesenzo esibuyela umva.
