Ivalve yolawulo lwepneumatic ijongana nevalve ye-rongjun yevalve yokulawula umoya imo yoqhagamshelo

Ivalve yolawulo lwepneumatic ijongana nevalve ye-rongjun yolawulo lwevalufa yepneumatic imo yokudibanisa ivalve yokulawula umoya phambi nasemva kokuba umahluko woxinzelelo mkhulu, kwaye amandla okuphuma kwe actuator awanelanga nawo aya kuvela impazamo yangaphakathi yokuvuza. Kufuneka ukhangele isizathu somahluko omkhulu woxinzelelo, yinkqubo yezinto, okanye impazamo yokukhetha, ukwandisa amandla okukhutshwa kwe-actuator ye-pneumatic, yindlela eqhelekileyo yokuphucula ukusebenza kokutywinwa, njengokulungelelanisa uluhlu lokusebenza lwentwasahlobo, tshintsha. ukuqina okuncinci kwentwasahlobo; Indawo eyongezelelweyo, lungisa uxinzelelo lomthombo womoya; Okwangoku akukho tshintsho, inokutshintshela kuphela kwi-activator ye-pneumatic enkulu. I-valve positioner luncamathelo olukhulu lwevalve yolawulo lwepneumatic, iya kumisa isignali yengxelo yokufuduswa njengemiqondiso yegalelo, njengoko isetiwe kwisilawuli sokuphuma komlawuli, uthelekisa, xa kukho ukutenxa, tshintsha indawo yevalve kwisiginali yokuphuma kweactuator, i actuator pneumatic. intshukumo, isiqu sevalve sisekiwe isignali yokufuduswa kobudlelwane obunye-to-enye kunye nomqondiso wokuphuma komlawuli, Inkqubo yokulawula impendulo ene-stem displacement njengomqondiso wokulinganisa kunye nesiphumo somlawuli njengoko isignali yokumisela isenziwa. Enyanisweni, ukusetyenziswa kwevalve ye-pneumatic kunye ne-valve yokulawula kubaluleke kakhulu, umgaqo osebenzayo we-FESTO valve yokulawula umoya: Ivalve yokulawula umoya ye-FESTO yenziwe nge-actuator kunye ne-regulating mechanism. I-activator yi-thrust part yevalve elawulayo, eyenza i-thrust ehambelanayo ngokobukhulu boxinzelelo lwesignali yokulawula kwaye ikhuthaze isenzo sendlela yokulawula. Umzimba wevalve yinxalenye elawulayo yevalve ye-pneumatic, enxibelelana ngokuthe ngqo nendawo elawulayo ukulawula ukuhamba kolwelo. Le valve yokulawula umphunga ayinakusebenzisa ukhuseleko olunjalo. Ngokombono, imiphumo emihle kunye nemiphumo emibi yendlela ye-valve yokulawula i-pneumatic inefuthe eliphambili kakhulu, ukuba awukhethi amagama afanelekileyo, kuya kuvelisa ubuninzi bokuphazamiseka. I-valve yebhola ye-Changchun ye-PVC kunye nebhola ebangela ukungqubuzana, kodwa umonakalo awuninzi, ngoko ubomi benkonzo yevalve yebhola ye-pneumatic buya kuba bude kune-valve yesango jikelele; Kulo lonke ulwahlulo lwevalvu yesango, ivalve yebhola yepneumatic ene-hydrodynamic friction resistance, ukuthanda umthengi, njengokuba wonke umntu eyazi ivalve yebhola yepneumatic, ukuxhathisa kwe-hydrodynamic kuncinci kakhulu. Qinisekisa ukuba indawo eyaneleyo ishiywe ngaphezulu nangaphantsi kwevalve ukuvumela ukususwa ngokulula kwe-actuator okanye i-spool ngexesha lokuhlolwa nokugcinwa. Umgama wesithuba unokufumaneka ngokwesiqhelo kwidayagram yomlinganiselo wemilo echongiweyo ngumenzi wevalvu yokulawula umoya. Kwimizimba ene-flanged, qiniseka ukuba ubuso be-flange bulungelelaniswe ngokufanelekileyo ukwenzela ukuba umphezulu we-gasket udibanise. Emva kokuba iiflange zilungelelaniswe, qinisa iibholiti ngobumnene, uze uziqinise ngendlela ephazamisayo. Iimveliso zenkampani zezi: ivalve yokulawula ipneumatic, ivalve yokulawula uxinzelelo, ivalve yokulawula umbane, ivalve elawulayo, ivalve elawula ukuhamba, ivalve elawula indlela ye-3, ivalve elawula ibhabhathane, ivalve yomphunga, isilawuli esinye, isitulo esinezihlalo ezibini, ifilimu. i-regulator, iivalve ze-pneumatic, iivalvu zokulawula umbane, iivalve zokulawula umoya, iivalve zolawulo zombane, njl. njl. Izibane zeflegi okanye amandla okuqhuba anokuba yi-pneumatic, umbane, ihydraulic, okanye nayiphi na indibaniselwano yezi zintathu. Amalungu omzimba wevalvu yinxalenye yohlengahlengiso lwevalvu yokulawula umoya, ukuxinana kweqokobhe levalvu, isiqu, i-spool, isihlalo, idlala kunye netywina. Banxibelelana ngokuthe ngqo ne-medium, phantsi kwempembelelo ye-actuator, batshintshe indawo yokuhamba phakathi kwe-spool kunye nesihlalo se-valve, ukuze bafezekise injongo yokulawula ukuhamba. Ivalve yokulawula umoya ineentlobo ezimbini zegesi evulekileyo kunye negesi evaliweyo. Umgaqo-siseko wokumisela indlela yokulawula i-valve switch kukuba: xa uxinzelelo lwesignali luphazamiseka, ukhuseleko lwezixhobo zenkqubo kunye nokuveliswa kufuneka kuqinisekiswe. Ukuba i-valve isendaweni evulekileyo emva kokuphazamiseka komqondiso, i-fluid ikhuselekile ngaphandle kokuphazamiseka, ngoko i-valve yokuvala igesi ikhethiwe; Ukuba ivalve ikwindawo evaliweyo emva kokuphazamiseka koxinzelelo lwesignali, i-fluid ayikhuselekanga nge **, ke ivalve yomoya isetyenziswa. Okufana nokufudumeza i-furnace fuel gas okanye i-fuel oil pipe elawula i-valve, kufuneka ikhethwe nge-valve yegesi, xa umqondiso uphazamiseka, i-valve ivalwe ngokuzenzekelayo, i-fuel inqunyulwe, ukwenzela ukuphepha ukushisa kwesithando somlilo kuphezulu kakhulu kunye neengozi; Ivalve elawulayo kumbhobho wokungena kwamanzi kwibhoyila kufuneka ikhethe ukusebenzisa igesi ukuvala ivalve. Xa umqondiso uphazamiseka, i-valve ivula ngokuzenzekelayo kwaye isathumela amanzi kwibhoyila, enokuthi iphephe ukutshisa kwibhoyila. I-valve yokulawula umoya weTaichen yimveliso yolawulo oluzenzekelayo oluzenzekelayo, i-actuator yefilimu ye-pneumatic, i-valve body, i-positioner kunye nokunye iseti epheleleyo yeemveliso zolawulo oluzenzekelayo, i-Taichen brand actuator ine-pneumatic piston actuator, i-pneumatic film actuator, igesi evulekileyo, igesi. vula iindidi ezimbini. Ulwakhiwo lomzimba wevalvu elawulayo sisitulo esinye esilawulayo ivelufa, ivelufa elawula imikhono, ivalve enezihlalo ezibini, ivelufa elawula iindlela ezintathu njalo njalo. Isikhundla sinokuxhotyiswa nge-Siemens yaseJamani, i-Japan Yamatu, i-Korea Yongtai YTC, i-United States Fisher, i-Wanxun, izixhobo, izixhobo ze-Wuzhong brand. Umgaqo osebenzayo wevalve yokulawula i-pneumatic uphela ekupheleni komqondiso wokuphuma kwenzwa, ngumgcini-ndawo ukwamkela umqondiso, ukuvulwa kwevalve yokulawula kunye nobukhulu bokuvala, ukulungiswa ngokuzenzekelayo koxinzelelo, ukuhamba, umgaqo wokushisa. Ezi nkcukacha zilandelayo zemodeli yebrand umsebenzi welocator. I-valve ye-solenoid ye-FESTO ayinakuguquguquka, ukwenzela ukuba igalelo kunye nezibonakaliso zemveliso azihambelani, kubangela i-oscillation. Ngeli xesha, indawo yokucoca i-valve yokunciphisa uxinzelelo lomoya kufuneka ivulwe, kwaye inxalenye ehambayo kufuneka ifakwe ngeoli yokuthambisa ukuphelisa ukungqubuzana. Njengomphumo wamandla angalinganiyo wevalve yokulawula umoya ngokwawo, i-spool elawulayo ihlala ivelisa i-oscillation. I-Zero spring force top incinci kakhulu, ukukwazi ukuxhathisa ukuphazamiseka kwangaphandle kuncinci, kwimeko yesignali encinci yangaphandle, kulula ukwenza i-spool vibration. Amagama aphambili: ivalve yokulawula umoya, ivalve yeRongjun, imowudi yoqhagamshelo lwevalvu yokulawula umoya
