Iimpawu zokuHamba kweValve eLawulayo

Iimpawu zokuhamba zolawuloivalveubukhulu becala ziindidi ezine zeempawu zokuqukuqela ezifana nepesenteji yomgca yokuvula ngokukhawuleza kunye neparabola. Xa ifakwe kwinkqubo yokulawula yokwenene, uxinzelelo lokwahlukana kweivalveiya kutshintsha ngotshintsho lokuhamba, oko kukuthi, ilahleko yoxinzelelo lwenxalenye yombhobho iya kuba yincinci xa ukuhamba kuncinci, uxinzelelo oluhlukileyoivalveiya kuba nkulu, kunye noxinzelelo olwahlukileyo lweivalveiya kuba ncinane xa ukuhamba kukukhulu Oku kwahlukile kwiimpawu zendalo zeivalveUphawu olubizwa ngokuba luphawu lokuhamba olusebenzayo lweempawu zokuqalisa ngokukhawuleza kwevalve yangaphakathi imilise idisk, ikakhulu isetyenziselwa ukuvula nokuvala isenzo.

Ukulawula imilo yomphezulu wevalve spool
Iimpawu zokulawula ukuhamba kweivalvezimiselwa ngokudityaniswa kweempawu zokuhamba kweivalvekunye nenkqubo umbhobho impompo, njl Ngokomlinganiselo weivalveIlahleko yoxinzelelo kwinto nganye yolawulo kunye nenkqubo, umlinganiselo welahleko yoxinzelelo lwevalvu kwinkqubo yento yolawulo ikhethwa kule theyibhile ilandelayo % ulawulo loxinzelelo okanye ulawulo lobushushu ngaphantsi kwe-50% yolawulo loxinzelelo okanye ulawulo lobushushu ngaphezu kwama-50% Linear kuba ilahleko yoxinzelelo lombhobho ngokomlinganiselo kwisikwere sokunyuka kwesantya sokuhamba, ukuba iimpawu zomzimba wevalve zilula utshintsho olunomgca, Uxinzelelo oluhlukeneyo lwevalve luyanda xa ukuhamba kuncinci, ukuhamba kwevalve kuya kuba kukhulu kakhulu, ukuhluka koxinzelelo lwevalve kuncipha xa ukuhamba kukhulu, kwaye ukuhamba akukwazi ukulingana nokuvulwa kwevalve Ukuza kuthi ga ngoku, ukongeza. iimpawu zombhobho kunye nempompo ukufezekisa ulawulo lokuhamba oluzimeleyo kubungakanani bokuhamba kunye nokulinganisa kuphela ukuvulwa kwevalve yinjongo yoyilo lweempawu zeepesenti ezilinganayo.

Inkqubo yemibhobho kunye nokulahleka koxinzelelo
Isenzo sevalve yokulawula sinokukhethwa ngokuhambelana nesixhobo sokuqhuba kunye nomzimba wevalve.

Ukuqhuba kunye nevalve yomzimba kunye nentshukumo yevalvu (umzekelo wevalve yesitulo esinye)
Intshukumo yeValve ibandakanya isenzo esilungileyo sokubuyela umva isenzo sohlobo lwesenzo 3 iindlela ze-diaphragm uhlobo kunye ne-cylinder yohlobo lwe-pneumatic drive isenzo esilungileyo ngokunyuka kophawu loxinzelelo UKUVALA indlela yevalve, ekwaziwa ngokuba yi-AIR UKUVALA intshukumo ebuyela umva kungokwanda kophawu loxinzelelo ukuya. VULA indlela yevalve, eyaziwa ngokuba yi-AIR ukuvula okanye Umqondiso wokusebenza kombane unokuguqulwa ube ngumqondiso we-pneumatic ngokusebenzisa i-locator. Xa umqondiso wokusebenza unqunyanyisiwe okanye umthombo womoya uphazamisekile kwaye umbane ucinyiwe, nceda ukhethe ivalve UKUVALA okanye uvule ngokuqwalasela ukhuseleko lwenkqubo..

Umzekelo, xa ulawula isixa acid ngokusebenzisaivalvekwinkqubo yokuxuba amanzi kunye ne-asidi, kukhuselekile kwaye kunengqiqo ukuvala ulawulo lwe-asidiivalvexa umgca wesignali yombane uphukile okanye umbhobho wesignali yomoya uvuza kwaye umthombo womoya uphazamisekile kwaye umbane unqunyulwe. Ivalve yentshukumo ebuyela umva kufuneka isetyenziswe.
