Ukufundisa ukusetshenziswa okufanele kwama-valve ukuze kuncishiswe izindlela eziqondile zokuhluleka kwe-valve evamile ama-valve ahlukahlukene ajwayelekile kanye nokungeniswa kwe-valve Ngoba ama-valve ahlukahlukene ohlelweni lwe-chiller ludlala indima yokulungisa nokulawula ukugeleza kwesitimu noketshezi. Ngakho-ke, ikhwalithi yomkhiqizo wayo idlala indima ebalulekile ekusebenzeni okuvamile kwesofthiwe yesistimu ye-industrial chiller. Ngesikhathi esifanayo, ukusebenza nokusetshenziswa kwe-valve akunaki ukuholela ekuvuzeni (okubandakanya ukuvezwa nokuvuza), ukuguqulwa kwe-valve, ukugoba, ukuqhekeka, njll, kuthinta ukusebenza okuvamile kwesistimu yokusebenza. Okunye ukwehluleka kwe-valve okuvamile kuvame ukuba umphumela wokusebenza okungalungile. Ngakho-ke, ukusetshenziswa okufanele kwama-valve kuyisiqinisekiso esiqinile sokunciphisa ukwehluleka okuvamile kwama-valve. Ngoba ama-valve ahlukahlukene ohlelweni lwe-chiller system adlala indima yokulungisa nokulawula ukugeleza kwesitimu noketshezi. Ngakho-ke, ikhwalithi yomkhiqizo wayo idlala indima ebalulekile ekusebenzeni okuvamile kwesofthiwe yesistimu ye-industrial chiller. Ngesikhathi esifanayo, ukusebenza nokusetshenziswa kwe-valve akunaki ukuholela ekuvuzeni (okubandakanya ukuvezwa nokuvuza), ukuguqulwa kwe-valve, ukugoba, ukuqhekeka, njll, kuthinta ukusebenza okuvamile kwesistimu yokusebenza. Okunye ukwehluleka kwe-valve okuvamile kuvame ukuba umphumela wokusebenza okungalungile. Njengoba i-valve enkulu yokuvula, ngaphandle komunye nomunye ngesikhathi sokunikezwa komsebenzi wokunikezela kucacile, yathatha ngemuva kokutholakala ngokusho kwedatha yedatha akwanele, ngephutha bacabange ukuthi i-valve ayivuli noma i-degree evulekile akwanele, ukufeza ukuvula futhi. , njengoba kukhethekile kwaqala ukunweba ingalo Futhi kunzima kakhulu futhi i-valve rod deformation, ukugoba, ukuphuka, njll. Ngakho-ke, ukusetshenziswa okufanele kwama-valve kuyisiqinisekiso esiqinile sokunciphisa ukuhluleka kwe-valve evamile. ① Uma i-valve ivuliwe futhi ivaliwe, kwenqatshelwe ngokuphelele ukusebenzisa amandla amaningi nokunweba ingalo yesikhashana. (2) Uma i-valve isezingeni elikhudlwana lokuvula, isondo lesandla kufanele lijikelezwe izikhathi ezingu-1 ~ 2 ukuze kuvinjelwe ukuvulwa kwawo wonke umcabango oyiphutha kuvalwe futhi kwenziwe umsebenzi wangempela. (3) i-valve stem yokugcwalisa uphawu lokugcwalisa impahla ekamelweni lokugcwalisa ayifaneleki kakhulu noma incane kakhulu, kuhle ukugoqa i-cap ngokuyisisekelo ingaphuthunyiswa phansi, ngesikhathi esifanayo kufanele igcine inani elithile lamafutha ukugcwalisa igumbi lempahla. Ukuze uvimbele ukuvuza eduze kwesiqu, nciphisa ukungqubuzana okomile, gwema ukulunywa kwesiqu, bese wenza ivalvu ivuleke futhi ivaleke kalula. I-valve engavamile ukusetshenziswa ingavulwa futhi ivalwe ngesikhathi ngaphansi kwesimo sokusebenza kahle kwesistimu. (4) i-valve ivala, uma umuntu engakwazi ukucisha okuvalwe, umgogodla we-valve uwukuthuthukisa ezinye, njenge-valve handwheel ukuvula indilinga ejikelezayo ye-azimuth ye-1 ~ 2), ukugeleza okusheshayo kwe-medium ohlelweni lwe-valve. ama-valve esango aphakathi nomfutho ophezulu wokugungiswa, ukususa ama-valve esango anomfutho ophezulu kanye nenhliziyo ye-valve yezinhlayiya ze-granular, ngemva kokukhiywa kanzima futhi. ⑤ Isondo lesandla kuvalvu akufanele lithathwe ukuze lisetshenziswe kulo, ukuze livinjwe ukuthi lingatholakali ekufakweni kwesimo esiphuthumayo. Kukho konke ukusebenza okuvamile noma kuvalvu ye-fluorine ngemva kokuvalwa, isivalo sokuvala kufanele siqiniswe ukuze kuvinjwe isiqandisi ukuthi singavuzi esiqwini sevalvu. Ngokuvamile, amanye amathuluzi akhethekile (njenge-wrench) awakwazi ukusetshenziselwa ukufaka esikhundleni se-valve handwheel ukwenza umsebenzi wangempela. Uma i-valve idinga ukuhlakazwa futhi ilungiswe, isiphetho sokuqala se-valve kufanele sihlakazwe futhi sinqanyulwe ku-software yesistimu, okungukuthi, cisha i-valve efanele, bese uvula i-compressor yesiqandisi, i-valve kanye nokuxhumana okuhlobene kwe-valve. Isiqandisi sephayiphi ngangokunokwenzeka. Ngesikhathi esifanayo, lungiselela ukuhlakazeka nokuhlanganiswa kusenesikhathi (isibonelo, gqoka amagilavu ​​enjoloba, lungiselela imaski yegesi yesofthiwe yesistimu ye-ammonia, futhi uvule ifeni ye-centrifugal ngezingozi zokuphepha ukuze kuqhutshwe umoya wemvelo). I-Disassembly akufanele ibhekane ne-valve yokugeleza eyodwa, ukugwema ukulimala kwekhefu le-vapor esiqandisini, ekuhlakazweni kwenati elilodwa le-valve yokugeleza, eyokuqala kufanele ibe yi-symmetrical loose kodwa akudingeki ithole, njenge-valve yokugeleza eyodwa exekethile, akukho khefu lesiqandisi. lapho uthulula, uma kusekhona ikhefu lesiqandisi, i-valve eyodwa yokugeleza kufanele isaqiniswe, thola isizathu bese ususa futhi ngemva kokuhlakazeka. Zonke izinhlobo zama-valve kanye nama-valve jikelele zifingqiwe A, ama-valve I-valve yebhola, izingxenye ezivulekile nezivaliwe (ibhola) ezishayelwa isiqu se-valve, futhi zizungeze umugqa omaphakathi wevalvu ukuze kwenziwe imisebenzi ejikelezayo yevalvu. Izici: 1, ukumelana nokugqoka: ngoba umnyombo we-valve yebhola eqinile yi-carbon steel spray welding, indandatho yokuvala i-carbon steel spray welding, ngakho-ke i-valve yebhola eqinile akulula ukudala umonakalo omkhulu lapho ushintsha amandla. (Inenkomba yokuqina ka-65-70) : 2, umsebenzi omuhle wokuvala: ngoba ukuvala i-valve yebhola eqinile ukusetshenziswa kokugaya komuntu, kuze kube yilapho umgogodla we-valve nendandatho yokuvala ihambisana ngokuphelele. Ngakho-ke isimo sakhe sokungangeni moya sinengqondo. 3, ukukhanya kokushintsha amandla: ngoba phansi kwendandatho yokuvala ye-valve yebhola eqinile isebenzisa i-torsion spring ukwenza indandatho yokuvala kanye nomgogodla we-valve ubambeke ndawonye, ​​ngakho-ke ukushintshwa kwamandla kukhanya kakhulu lapho amandla angaphandle edlula amandla okuqinisa ngaphambili. umthombo we-torsion. I-4, impilo yesevisi ende: isetshenziswe kabanzi kuwoyela ongahluziwe, izitshalo zamakhemikhali, ukukhiqiza amandla, imboni yephepha, amandla enuzi, izindiza, amarokhethi kanye namanye amayunithi, kanye nempilo yansuku zonke yawo wonke umuntu. Inzuzo: Izinzuzo: 1, ukuvimbela uketshezi kuncane, futhi i-coefficient yayo yokumelana iyafana nepayipi yosayizi ofanayo. 2, isakhiwo esilula, usayizi omncane, isisindo esilula. I-3, eduze ne-spectrum, kanye nezinto zokusetshenziswa kwe-valve surface esetshenziswa ipulasitiki, umoya omuhle, kudivayisi ye-ultrafiltration nayo isetshenzisiwe. 4. Ukusebenza okusebenzayo kulula, ukuvula nokuvala ngokushesha, udinga kuphela ukuzungeza i-90 ° kusukela ekuvuleni kuya ekuvaleni, okuhambisana nokusebenza okukude. 5, ukugcinwa okulula, ukwakheka kwe-valve yebhola elula, indandatho yokubeka uphawu ngokuvamile iyisenzo, ukuqaqa nokushintshwa kulula kakhulu. I-6, ukusetshenziswa okubanzi, ububanzi bepayipi kusuka kumamilimitha amancane kuya kwambalwa, amakhulu kuya kumamitha amangaki, ipompo ye-vacuum ephezulu noma umfutho ophezulu ungasetshenziswa. Okubili, i-valve yokumisa (1) I-valve yesango lomlilo: zungezisa isondo lesandla ukuze uphakamise noma wehlise ipuleti elinezimbotshana elixhunywe nesiqu se-valve ngokuya kusengaphambili noma ukuhoxiswa kwamazinyo ayisikulufu sesondo lesandla kanye nesiqu se-valve, ukuze unike amandla. bese uvala umsebenzi. Ama-valve esango lomlilo anezinzuzo ezilandelayo: 1, ukuvinjelwa kwe-liquid kuncane, indawo engaphezulu iyagezwa futhi igxilwe yi-medium. 2, vula futhi uvale umzamo owengeziwe. I-3, ukungena okuphakathi akukhawulelwe, akukho siphithiphithi, akukho ukuncipha kwengcindezi. I-4, umzimba olula, usayizi wesakhiwo esifushane, ukukhiqizwa okuhle nokusebenza kwenqubo yokukhiqiza, inkambu ebanzi yesicelo. Ukukhubazeka kwe-valve yesango lomlilo kungokulandelayo: 1, indawo ephakathi nendawo kulula ukubangela ukuguguleka nokuhuzuka, ukugcinwa kunzima kakhulu. 2, ubukhulu bukhulu ngokuqhathaniswa, ukuvulwa kufanele kube indawo ethile yasendlini, ukuvulwa okude nokuvala isikhathi. 3, isakhiwo siyinkimbinkimbi. (ezimbili) i-valve yesango lenduku emnyama: ebizwa nangokuthi i-rotary rod globe valve (ebuye ibizwe ngokuthi ivalve yesango ye-dark rod wedge). I-stem nut ihlelwe ku-valve yesango, futhi isondo lesandla liyajikeleza ukuze lisunduze isiqu ukuze sijikeleze, futhi i-valve yesango iyaphakanyiswa. Ngokuvamile kunentambo ye-trapezoidal phansi kwesiqu. Ngokuvumelana nezikulufu zamazinyo angaphansi kwe-valve kanye negroove eqondisayo kuvalvu ye-piston, umsebenzi wokuzungezisa uba ukunyakaza okufana komugqa, okungukuthi, itorque yangempela yokusebenza iba amandla okushayela angempela. I-valve ye-disc: i-valve ye-butterfly, eyaziwa nangokuthi i-valve ye-flap hook, iyisakhiwo esilula se-valve elawulayo, ingasetshenziswa njengephayiphi le-voltage eliphansi eliphakathi nendawo yokulungisa i-disc valve ukuvala izingxenye (i-piston valve noma ipuleti levemvane) ukuze i-disc, iqinise eduze kwe-valve shaft ukuze ivule futhi ivale i-valve. Okwesine, i-valve yokumisa: i-valve yokuhlola ibhekisela ekugelezeni kwe-medium ngokwayo kanye ne-valve ye-piston evulekile ngokugcwele futhi evala, esetshenziselwa ukugwema i-valve ephikisanayo ephakathi nendawo, eyaziwa nangokuthi i-valve ehlanekezelayo, i-throttle valve, i-valve ehlehlayo, ne-valve yokucindezela emuva. I-valve yokuhlola iyingxenye ye-valve ezenzakalelayo, umsebenzi wayo oyinhloko ukugwema i-countercurrent ephakathi, ukugwema iphampu futhi ukhuthaze injini ukuba iphenduke, kanye nezitsha zayo zokukhululwa okuphakathi. Eyesihlanu, i-valve: i-valve yokuphepha yizingxenye ezivulekile nezivaliwe ngaphansi kwamandla angaphandle atholakala esimweni esivame ukuvaleka, lapho ingcindezi ephakathi nendawo noma ipayipi ikhuphuka ngaphezu kwenani elijwayelekile, ngokusho kwesistimu ukuvimbela ukucindezela okuphakathi ipayipi noma izinsiza ezingaphezu kwedatha eshiwo ye-valve eyingqayizivele. I-valve ingeyesigaba se-self valve, ikakhulukazi esetshenziselwa ukushisa esithandweni, isitsha sokucindezela kanye nepayipi, ingcindezi yokusebenza ayidluli inani elijwayelekile, ngokuphepha kwempilo kanye nokusebenza kwezikhungo zomphumela oyinhloko wesiqinisekiso. Okuyisithupha, ukuvuza okuphansi kanye ne-valve yokuvala ephezulu: indima yokuvuza okuphansi kanye ne-valve yokuvala ephezulu: ukugwema isofthiwe yesistimu ngenxa yokunqwabelana kokuvuza kwesitimu okubangelwa ukusebenza okungalungile kwesofthiwe yohlelo futhi yafakwa ku-valve yepayipi. Ifakwe epayipini lokuqalisa, ngokuvamile esimweni esivulekile, kuphela ekucindezelweni kwe-inlet ukusetha ingcindezi yokuvala, umsebenzi wayo oyinhloko ukukhipha ukuvuza ngenxa ye-valve yomoya eyisikhombisa, i-valve elawula ukucindezela (a) i-valve yokunciphisa ingcindezi elinganayo. : ukuvulwa kwe-valve yokushayela konke kungokusebenzisa ibhawudi lehange eliphezulu lokulungisa iwashi ngokulandelana kwewashi, ukuze ukunwebeka okubangelwa ukufinyela kwe-torsion spring, ukuze i-valve yomshayeli ishaye i-damper ibophele, umphumela wamandla ku-crankshaft ye-valve yomshayeli, ukuze offset phansi ukuvula valve umshayeli. Lapho kuvulwa i-valve yokushayela, isitimu esikhuphuka nomfula esingezansi komfula singena endaweni engu-A yesigaba sepayipi lesitimu ngokusebenzisa isiteshi sokuphepha esingu-α (umzila wokuphepha wokulungisa umusi), ngevalvu yokushayela ingene endaweni eyindandatho ye-valve yomshayeli, isuka esiteshini sokuphepha u-β ngokushesha. ithunyelwe esifubeni nasemgodini wesisu we-piston rod cylinder ngezansi. Ngaphansi kokunikezwa okuqhubekayo komhwamuko ekamelweni A, ingcindezi ikhuphuka ngokuqhubekayo, okukhuthaza induku ye-piston ukuthi islayide futhi ivule i-valve yokusabalalisa. Ngalesi sikhathi, umfudlana ongapheli womhwamuko ugeleza usuka kugumbi A uye kugumbi B. Lapho umthwalo osegumbini B lengxenye yokungena neyokuphuma phakathi nendawo ephansi nomfula ufinyelela, isitimu eseqile senza ukucindezela kwegumbi B kuqhubeke nokukhuphuka. Ingcindezi eqhubekayo ekhuphukayo ngokuya ngesiteshi sokuphepha γ (isiteshi sokuphepha sokungenisa ingcindezi kazibuthe) impendulo egunjini lokushayela i-valve pulse damper, i-diaphragm ye-valve yomshayeli i-diaphragm phezulu i-convex, susa umkhawulo ongaphezulu wokulungiswa komfutho we-torsion spring, i-valve yokushayela. incane noma ivaliwe. Ngaphezu kwalokho, yehlisa noma uvale umthombo womhwamuko ovela enhla nomfula u-α udlula ngendlela ephephile. Lapho ukucindezela kwesifuba nesisu sesilinda senduku ye-piston kuncishisiwe, i-valve yokusabalalisa iyalungiswa noma ivalwe ngaphansi komphumela wokulinganiswa kwentwasahlobo ye-torsion ngezansi, khona-ke ukucindezela ku-B cavity kuyehla kancane kancane, ukuze kuzuzwe umgomo we-torsion spring calibration ngezansi. umjikelezo we-transformer. (ezimbili) i-valve yokulawula ingcindezi yohlobo olusheshayo: umphumela osheshayo we-torsion spring ifilimu yefilimu uhlobo lwengcindezi elawula i-valve umphumela osheshayo we-torsion spring ifilimu yefilimu uhlobo lokucindezela ukhiye we-valve ngokulungisa isiphethu se-torsion, i-pulse damper, induku yepiston, i-valve yesango lokucindezela okukhulu, i-piston valve nokunye. izingxenye. I-Pulse damper isetshenziselwa ukusunduza ngokushesha i-valve ye-piston futhi ulungise izinga lokuvula le-disc yokucindezela ukuze ukhulule ingcindezi futhi uzinze ishubhu lokucindezela. (3) I-valve yokulawula ingcindezi ehamba phambili: I-valve elawula ukucindezela isetshenziswa ku-valve yokusiza umshayeli esebenza emzimbeni wokuvula nokuvala i-medium ukulungisa ukuvuleka kwethrafikhi, ukunciphisa ingcindezi ye-medium, ngesikhathi esifanayo bathembele. ngomphumela we-valve ngemva kokulungiswa kwengcindezi yokuvula nokuvala, gcina i-valve ngemva kokucindezela endaweni ethile, ingcindezi yoshintsho oluqhubekayo oluvela kwamanye amazwe, ukugcina isigaba sokucindezela kwangaphakathi nangaphandle ekumisweni Ngemva kokugcinwa kokukhiqizwa kokukhiqiza ukuphila kwansuku zonke. imishini. I-valve yebhola eyisishiyagalombili: izintanta zidinga ukuntanta olwandle kusukela ekuqaleni kuye ekugcineni, lapho umfula ukhula, izintanta nazo zilandela ukukhuphuka. I-Drift up iphushela i-crankshaft phezulu. I-crankshaft ixhunywe kuvalvu ngakolunye uhlangothi, futhi lapho iphakanyiswe endaweni ethile, i-crankshaft isekela i-plastic piston rod pad, evalwe ngamanzi. Njengoba izinga lamanzi lehla, i-float iyawa, futhi i-crankshaft iphusha i-piston rod pad ivuleke.
