Umsebenzi we-valve kanye nezici okufanele zicatshangelwe lapho kukhethwa izici eziyinhloko zokusebenza kwe-valve yesilawuli se-valve kagesi

Umsebenzi wevalvu nezici okufanele zicatshangelwe lapho kukhethwa idivayisi kagesi yesilawuli esihlakaniphile izici eziyinhloko zokusebenza Ukukhethwa kwevalvu kusekelwe ekusebenzeni nokuphepha nokuqonda komnotho, ukuqhathaniswa kwebhalansi okuphelele kwemiphumela yobufakazi. Lezi zimo zokuqala ezilandelayo kufanele zethulwe ngaphambi kokukhethwa kwevalvu: 1, izakhiwo ezibonakalayo (1) Isimo se-Material a. Isimo esibalulekile sezinto ezinegesi sihlanganisa: idatha yendawo ebonakalayo ehlobene, igesi emsulwa noma ingxubevange, noma ngabe kukhona amaconsi noma izinhlayiya eziqinile, nokuthi ingabe zikhona yini izingxenye okufanele zifinyele. b. Isimo esibalulekile sezinto eziwuketshezi sihlanganisa: (1) Idatha yendawo ebonakalayo ehlobene, kungakhathaliseki ukuthi ingxenye emsulwa noma ingxube iqukethe izingxenye eziguquguqukayo noma igesi encibilikisiwe (enganelwa ukuze yakhe ukugeleza kwezigaba ezimbili lapho umfutho wehla), noma ngabe iqukethe okuqinile. udaba olumisiwe, kanye ukungaguquguquki, iphuzu okokuqandisa noma uthele iphuzu uketshezi. (2) Ezinye izakhiwo; Kubandakanya ukugqwala, ubuthi, ukuncibilika kwezinto zokwakha ze-valve, noma ngabe ziyavutha noma ziqhuma ukusebenza. Lezi zakhiwo ngezinye izikhathi azithinti kuphela izinto ezibonakalayo, kodwa futhi zibangele izidingo ezikhethekile zesakhiwo, noma isidingo sokuthuthukisa ibanga lepayipi. 2. Izimo zokusebenza ngaphansi kombuso wokusebenza (1) Ngokusho kokushisa nokucindezela ngaphansi kwezimo ezijwayelekile zokusebenza, kuyadingeka futhi ukuhlanganisa izimo zokusebenza zokuvula nokuvala noma ukuvuselelwa. a. I-valve yokuphuma yepompo kufanele icabangele ukucindezela okukhulu kokuvala kwepompo. b. Lapho izinga lokushisa lokuvuselelwa kwesistimu liphakeme kakhulu kunokushisa okuvamile ngenkathi ukucindezela kuncipha, umphumela ohlangene wokushisa nokucindezela kufanele ucatshangelwe kulolu hlobo lwesistimu. c. Izinga eliqhubekayo lokusebenza: okungukuthi, imvamisa yokuvula nokuvala i-valve nayo ithinta izidingo zokumelana nokugqoka. Kuzinhlelo ezinokushintshwa njalo, noma ukufaka ama-valve kabili kufanele kucatshangelwe. (2) Ukwehla kwengcindezi okuvunyelwe kohlelo a. Uma ukwehla kokucindezela okuvunyelwe kwesistimu kukuncane, noma ukwehla kokucindezela okuvunyelwe akukukhulu kodwa ukulawulwa kokugeleza akudingeki, uhlobo lwe-valve olunokwehla kokucindezela okuncane kufanele lukhethwe, njenge-valve yesango kanye ne-valve yebhola eqondile. B. Uma izinga lokugeleza lidinga ukulawulwa, uhlobo lwevalvu olusebenza kangcono olawulayo kanye nokwehla kwengcindezi ethile kufanele kukhethwe (ingxenye yokwehla komfutho kukho konke ukwehla komfutho wepayipi ihlobene nokuzwela kokulawula). (3) Indawo lapho i-valve ikhona: ngaphandle ezindaweni ezibandayo, ikakhulukazi izinto zamakhemikhali, impahla yomzimba ngokuvamile ayiyona insimbi ewuketshezi kodwa insimbi ewuketshezi (noma insimbi engagqwali). 3. Ukusebenza kwevalvu (1) Kunqanyuliwe: Cishe wonke amavalvu anqamule ukusebenza. Ukusetshenziselwa ukusika ngaphandle kokulungisa ukugeleza kungakhethwa i-valve yesango, i-valve yebhola, njll., Ukusika ngokushesha, iqhude, i-valve yebhola, i-butterfly valve ifaneleka kakhulu. I-valve ye-globe ingakwazi kokubili ukulungisa ukugeleza nokunqanyulwa. I-valve ye-Butterfly nayo ingafaneleka ukulungiswa okukhulu kokugeleza. (2) shintsha isiqondiso sokugeleza: ukukhethwa kwe-valve yebhola yezindlela ezimbili (isiteshi esimise u-L) noma indlela emithathu (emise okwe-T) noma iqhude, ingashintsha ngokushesha isiqondiso sokugeleza kwezinto, futhi ngenxa yokuthi i-valve idlala indima. amabili noma ngaphezulu aqonde ngamavalvu, angenza ukusebenza kube lula, enze iswishi inembe, futhi inganciphisa isikhala. (3) Ukulawula: i-globe valve, i-plunger valve ingahlangabezana nomthethonqubo wokugeleza jikelele, i-valve yenaliti ingasetshenziselwa ukulungiswa okuncane okuhle; Ebangeni elikhulu lokugeleza lokulawulwa okuzinzile (ukucindezela, ukugeleza), i-throttle valve ifanelekile. (4) Hlola: I-valve yokuhlola ingasetshenziswa ukuvimbela ukubuyela emuva kwezinto. (5) Amavalvu anezici ezengeziwe angakhethelwa izinqubo ezihlukene zokukhiqiza, njengamavalufu anebhantshi, anembobo yokuphuma kanye ne-bypass, namavalvu ane-vent ukuvimbela ukufakwa kwezinhlayiya eziqinile. I-4, amandla e-valve yokushintsha In situ yokusebenza kweningi levalvu enesondo lesandla, nokusebenza ngebanga elithile, kungasetshenziswa i-sprocket noma induku enwetshiwe. Amanye ama-diameter amakhulu aklanywe ngama-motor ngenxa ye-torque yokuqala ngokweqile. Ibanga elihambisanayo lenjini evikela ukuqhuma kufanele isetshenziswe endaweni evikela ukuqhuma. I-valve yesilawuli kude: thatha uhlobo lwamandla womoya, i-hydraulic, kagesi, engahlukaniswa i-solenoid valve kanye ne-motor driven valve. Ukukhetha kufanele kusekelwe esidingweni namandla atholakalayo. Idivayisi kagesi elawula ivalvu ehlakaniphile ifaneleka kwamanye amavalvu ajikelezayo (njenge-butterfly valve, i-valve yebhola kanye ne-damper baffle, njll.) nezinye izinto ezifanayo. Ubakaki ungasetshenziswa njenge-Angle stroke actuator kagesi. Aluminium ingxubevange die casting igobolondo, ne emihle futhi abushelelezi, ivolumu encane, isisindo ukukhanya, ukugcinwa mahhala, ukugqwala ukumelana kanye nezinye izakhiwo ezinhle kakhulu, ngenxa usayizi compact, ingasetshenziswa ezindaweni emincane. Izici zokusebenza zedivayisi kagesi ye-valve ehlakaniphile 1. I-motor enamandla EYENZELWE ukusebenza kwe-valve IZICI EZIQALAYO I-TOQUE EQALAYO ephezulu, I-INERTIA EYAQALA IYAQALA PHANSI NJENGAMANJE KANYE AYIPHENDUKE PHANSI. I-Stator windings ifakwe isivikeli esishisayo esakhelwe ngaphakathi (uhlobo lokutakula okuzenzakalelayo). Lapho i-valve inamathele ngokungalindelekile, umvikeli uzolawula injini ukuze amise futhi avikele ukuphepha kwayo yonke isethi yemishini. I-2, ivolumu encane, i-torque enkulu Ivolumu nesisindo silingana ne-1/3 yemikhiqizo yendabuko efanayo; Amandla okufakwayo jikelele mancane, i-torque yokukhipha inkulu, futhi indawo yokufaka edingekayo incane; Kulula kakhulu ukufaka nokuthutha. I-3, i-valve yokuvula isibonisi I-Lens nomzimba ngokuhlangana kwengilazi yebanga lokudla kwamanye amazwe, ukuphakama kwebhondi kuqinile, ukuze umkhiqizo ungangcoliswa, ukumelana nokushisa okuphezulu, ungamelana ngokuphumelelayo namathani emvula e-bubble corrosion endaweni embi. I-4, idivayisi yomkhawulo wemishini Cha, ibhawudi elikhawula lokuhamba elisebenza ngomshini kanye nebhulokhi yomkhawulo eyenziwe ngensimbi engagqwali ingalungisa indlela yokuhamba iye ku-Engeli oyifunayo. Ukuze kube lula ukulungisa, i-bolt ibekwe ngaphandle kwendlu. Ngemuva kokulungiswa ngakunye, indawo oyifunayo ikhiyiwe ngensimbi engenasici. 5. Isibambo sensimbi engagqwali singasetshenziswa ukushayela ivalvu ukuze ivuleke lapho kulungiswa amaphutha noma icishiwe, S ngokuqondisa kwewashi, O ngokuqondisa okuphambene newashi. 6, igiya elinembayo LAkhiwe AMAGARIYA AMANINGI KANYE NEMISHAFU YE-PRECISE TANGENT. Amagiya namashafti enziwe ngensimbi ene-alloy ephezulu ephethwe ukushisa, enamandla amakhulu nokubekezela okuhle futhi ekwazi ukumelana nomthelela womthwalo wokukhathala wesikhathi eside. Igrisi yesisekelo se-molybdenum engenisiwe yengezwe emshinini wegiya ukuze kuqedelwe ukugcotshwa ngaphandle kokuhlolwa kwendawo noma ukulungiswa. 7. Isixhumi esibonakalayo sekhebula Ifakwe izixhumi ezimbili zekhebula ezingangeni manzi ze-G1/2 zezintambo zekhebula nezimpawu zokuvimbela ukuphazamiseka. I-8, i-micro switch ye-HD uchungechunge khetha i-micro switch engenisiwe, ikhwalithi yokuxhumana, impilo yesenzo, ukusebenza kwe-insulation nezinye izinkomba zinhle kakhulu futhi zithembekile. 9. Indlela ye-Servo Imojuli yokulawula eyakhelwe ngaphakathi ihlale iqhathanisa isignali yokufaka kanye nesignali yempendulo ye-potentiometer. Lapho ibhalansi ifinyelelwa, injini izoyeka ukusebenza, futhi i-shaft yokuphuma izogcina i-valve endaweni ehambisanayo kuze kube yilapho isignali yokufaka ishintsha. Qinisekisa ukulungiswa okuqhubekayo kokuvuleka kwe-valve. 10. Imojula yokulawula I-resin encapsulated control module inezici ezinhle kakhulu zokubola okuphezulu, umsebenzi oqinile, ukumelana nokudlidliza, impilo ende nokuthembeka. 11, ukunemba potentiometer Kungeniswe izinga okusezingeni eliphezulu potentiometer, impilo yesevisi izikhathi ezifika ezinkulungwaneni ezingamashumi amathathu! Ifanele kakhulu izidingo zokulungiswa kokuvula i-valve encane! Qinisekisa ngokuphumelelayo ukulungiswa okunembayo kwe-valve kagesi. 12. Ukulawula okuzenzakalelayo Idivayisi ehlanganisiwe ehlakaniphile enesignali engu-4 ~ 20mADC okokufaka nokuphumayo kungalawulwa yikhompyutha ye-PLC kanye nohlelo lwe-DCS, ukulawulwa ngokulinganayo nokubeka indawo, ngaphandle kokulawula ngesandla, ukuvala isikhundla, uxhumano olulula, ukusebenza okuzinzile nokuthembekile, ukunemba kokulawula okuphezulu. , isivinini sokuphendula esisheshayo.
