Ivalvu yebhola kagesi yephrojekthi yokuhlaziya igesi kufanele ihlolwe njengengxenye yendlela yokulinganisa, hhayi njengengxenye evamile yokuvala. Ukucaciswa kokuthenga kudinga ukuchaza ukuthi yini edlula kuvalvu, ingcindezi nezinga lokushisa kuvalvu, ukuhlelwa kwembobo, izinto ezimanzi, imfuneko yokuvala, usayizi wokuxhuma, amasiginali we-actuator namasignali okulawula, umsebenzi womjikelezo, impendulo kanye nendawo yokuphelelwa amandla. Lezo zinkambu zinquma ukuthi i-valve ingakwazi ukuhlukanisa, ukukhetha noma ukukhipha umugqa ngaphandle kokunciphisa uhlelo noma ukuphazamisa isampula. Intengo yeyunithi ephansi inencazelo encane uma i-valve ecashuniwe ingafani nesekhethi yangempela yoketshezi noma ukwakheka kokulawula.
Umsebenzi Wevaluvu Uza Ngaphambi Kosayizi Wevavu
Amasistimu okuhlaziya igesi angasebenzisa ama-valve asebenza ngogesi ezindaweni eziningana: ukukhethwa kwesampula, ukungeniswa kwegesi yokulinganisa, ukuhlukaniswa kwe-bypass, ukukhishwa kwe-condensate noma ukushintsha phakathi kwemifudlana yenqubo. Le misebenzi ayishintsheki. I-valve evezwe kuphela kugesi yokulinganisa ehlanzekile ibhekana nempahla ehlukene kanye nezidingo zokuhlanzeka kusukela ekubambeni kwesampula yegesi emanzi noma i-condensate eqoqiwe.
Qala ngesitatimende somsebenzi esinomusho owodwa. Kufanele ihlonze uketshezi, indlela evamile yokugeleza, isimo sevalvu esilindelekile, imvamisa yokushintsha kanye nomphumela wokuvuza. Abathengi bayabuyekeza igesi analyzer izesekeli asizayo angakwazi ke ukuqhathanisa i-valve ne-probe ezungezile, isisefo, isipholile, iphampu kanye neshubhu esikhundleni sokuyiphatha njengento yekhathalogi ezimele yodwa.
| Umsebenzi wevalvu | Ulwazi okufanele luchazwe | Kungani kushintsha ukukhetha |
| Ukuhlukaniswa kwesampula | Ukwakheka kwegesi, ukucindezela okuvamile, izinga lokushisa, izinhlayiya kanye nengozi ye-condensate | Lezi zimo zithinta izinto ezimanzi, ukuvalwa kanye nokwenzeka kokungcoliswa noma ukunamathela. |
| Ukukhethwa kokusakaza noma ukulinganisa | Inombolo yezimbobo, ukulandelana kokugeleza, ukuvuza kwezimbobo ezivunyelwe kanye nesikhathi sokushintsha | Ukuqonda kwembobo nevolumu yangaphakathi kuthonya ukuthi ukusakaza okukodwa kungadlulela esilinganisweni esilandelayo. |
| I-condensate drain | Ukwakheka koketshezi, ukucindezela kokukhipha amanzi, okuqinile kanye nobude besikhathi sokuvula obudingekayo | Ivalvu elungele umoya ohlanzekile ingase ingafaneleki i-condensate ene-asidi noma enezinhlayiya. |
| Ukuhlukaniswa kokuphepha noma ukuvala shaqa | Indawo edingekayo ngemva kokuphelelwa amandla, impendulo kanye nengqondo yokuvala shaqa | Ukuziphatha kwe-actuator kufanele kuvumelane nefilosofi yokulawula kunokuba kuthathwe egameni elithi "ugesi." |
I-valve yebhola ijwayele ukukhethwa isevisi yokuvula noma yokushintsha. Uma iphrojekthi idinga ukunyakaziswa okuphindaphindwayo, umthengi kufanele asho lokho ngokucacile futhi aqinisekise ukuthi i-valve enikeziwe kanye ne-actuator yakhelwe umsebenzi wokumodulating. Ukuhlanganisa okujwayelekile kwekota-turn shutoff akufanele kuthathwe njengevalvu yokulawula ngoba nje ingama endaweni emaphakathi.
Qinisekisa Uketshezi Lwangempela, Kuhlanganisa Okuvela Ngesikhathi Sokucasuka
"Isevisi yomoya" akuyona incazelo ephelele yevalvu yokuhlaziya. Umfudlana ungaqukatha amagesi abolayo, umhwamuko wamanzi, ama-aerosol, uthuli noma uketshezi lokuhlanza. Ukupholisa kungase futhi kudale uketshezi lapho incazelo yenqubo ibala igesi kuphela. Ngakho-ke isheke lempahla elifanele limboza umzimba wevalvu, ibhola, isiqu, izihlalo, izimvu zamanzi kanye nazo zonke ezinye izingxenye ezimanzi.
Ukuhambisana kuthinta ngaphezu kokugqwala. Ezinye izakhi zesampula zingakhangiswa ngokuphezulu noma zivaleleke ezindaweni ezifile, kuyilapho izinhlayiya zingase ziphawule izihlalo futhi zikhuphule ukumelana nokusebenza. Leyo miphumela ingase iguqule impendulo, idale inkumbulo phakathi kokusakaza noma ivimbele ukuvala ukuvala okuphelele. Umphakeli udinga i-matrix yegesi elindelekile nezimo ezingavamile, hhayi nje igama lomhlaziyi oyinhloko.
Inhlanzeko nayo idinga incazelo yokuthenga. Ulayini wokulinganisa ungadinga ukuvikeleka kuwoyela, imfucumfucu yokuhlanganisa noma izinsalela zokuhlanza. Ku-valve yokudonsa amanzi, umbuzo obaluleke kakhulu ungaba ukuthi iphasishi langaphakathi lingakwazi yini ukusula izinto eziwuketshezi nezimisiwe. Lezi yizinkinga ezihlukene zokwamukela, ngisho noma womabili ama-valve esebenzisa uxhumano olufanayo lwegama.
Ingcindezi, izinga lokushisa kanye nokuhamba ngebhayisikili Kunquma Isidingo Se-Actuator
Ukulinganisa kwe-Actuator akukwazi ukuhlukaniswa nezimo zokusebenza kwamavalvu. Isiqondiso sobunjiniyela esishicilelwe samavalvu ebhola acushiwe sibonisa ukuthi itorque edingekayo ingashintsha ngokucindezela kwesistimu, izinga lokushisa, impahla yokuhlala, i-process medium kanye nemvamisa yomjikelezo. Yingakho i-valve ehamba ngokukhululekile ngesikhathi sokuhlolwa kwebhentshi elingalayishiwe ingase iziphathe ngendlela ehlukile ngemva kokufakwa.
I-RFQ kufanele inikeze ingcindezi evamile nephezulu echwebeni ngalinye elifanele, ingcindezi ephezulu yokuhluka ngesikhathi sokushintsha, izinga lokushisa elincane neliphezulu loketshezi, izinga lokushisa elizungezile kanye nemijikelezo elindelekile ngehora noma ngosuku. Umphakeli angabe eseqinisekisa ukuthi ukuhlanganisa okuhlanganisiwe kwe-valve-actuator kunomkhawulo owanele womsebenzi wangempela. Isibalo samandla emoto sisodwa asibonisi ukuthi i-valve izovuleka futhi ivale ngaphansi kwengcindezi ehlukanisiwe eshiwo.
Imvamisa yomjikelezo ibalulekile ngenye indlela: ichaza ukuthi ivalvu enensa noma engathembekile ikuthinta ngokushesha kangakanani ukutholakala kwedatha. I-valve yokukhetha umfudlana ingase isebenze izikhathi eziningi ngokushintshana ngakunye, kuyilapho i-valve yokuhlukanisa ingase ihlale endaweni eyodwa amasonto. Izikhathi ezinde zokungenzi lutho, ukuhamba ngebhayisikili njalo kanye nokuchayeka kwe-condensate ngezikhathi ezithile kuveza ubungozi bokwehluleka obuhlukene. Ikhotheshini kufanele ihlonze umsebenzi osetshenziselwa ukukhetha kanye nanoma imuphi umkhawulo oncike ekugibeleni amabhayisikili.
I-Port Geometry kanye nevolumu yangaphakathi ithinta ikhwalithi yokukala
Usayizi wokuxhumana ovamile awuvezi indlela yokugeleza yangaphakathi. Umthengi futhi udinga inombolo yezimbobo, indawo yokubhoboza noma ukugeleza okusebenzayo, imephu yembobo kanye ne-coefficient yokugeleza lapho ukwehla kwengcindezi kubalulekile. Umkhawulo unganciphisa ukugeleza kwesampula futhi wandise isikhathi sokuthutha. Ivolumu yangaphakathi eyeqile ingandisa isikhathi sokuhlanza lapho ushintsha ukusuka kugesi wenqubo uye kuqanda noma i-span gas.
Kuzinhlelo zokusakaza-bukhoma okuningi, umdwebo kufanele wenze ubudlelwano phakathi kwendawo ye-actuator nezimbobo ezixhunyiwe bube sobala. Imigomo efana nokuvula ngokuvamile, ukuvalwa ngokuvamile, imbobo ye-L ne-T-port azanele ngaphandle kwalapho umphakeli ebonisa izinombolo zembobo nokushintsha izindawo. I-logic yesilawuli, umdwebo weshubhu kanye nomdwebo wevalvu kufanele uchaze indlela yokugeleza efanayo.
Ukuvuza kunezincazelo ezimbili ezihlukene lapha. Ukuvuza kwangaphandle kuyinkinga yokuvimbela; ukuvuza kwezihlalo zangaphakathi kungaxuba imifudlana engayodwa noma kuvume umoya we-ambient. Ngakho-ke indlela yokuhlola eyamukelekayo kanye nomkhawulo kufanele kuxhunywe emsebenzini wevalvu. Ukuvuza kwembobo encane okungabalulekile kumjikelezo wosizo olulodwa kungase kucheme ukulinganisa kwezinga eliphansi noma kuphazamise ukulandelana kokulinganisa kwenye.
I-Electrical Interface Kumele Ifanise Ifilosofi Yokulawula
Ukucaciswa kwe-actuator kagesi kudinga okungaphezu kwamandla kagesi. Rekhoda i-voltage nokuhlukahluka okuvumelekile, okungaguquki nokuqala kwamandla, okokufaka kokulawula, inombolo yezintambo, indlela yokushintshashintsha, isikhathi sohambo, inkomba yendawo, ukuziphatha kokuphela kohambo kanye nesixhumi noma ukuhlelwa kwekhebula. Uma iKhabhinethi yokulawula ilindele othintana nabo abomile kodwa i-valve idinga isignali ye-voltage egcinwe, ukungafani kuzovela kuphela ngesikhathi sokufaka izintambo noma ukuthunywa.
Ukuziphatha kokulahlekelwa amandla kufanele kubhalwe njengendawo edingekayo, hhayi isicelo esingacacile sesimo "esiphephile". Isimo esifanele sincike kumjikelezo. I-valve yokulinganisa ingase idinge ukuvala, i-valve yokudonsa ingase idinge ukuthi ihlale ivaliwe kuze kube yilapho iyalwa, futhi olunye uhlelo lokusebenza lungadinga indawo echaziwe yokubuyisela. Uma i-actuator inganikezi ukubuyisela okuzenzakalelayo, umklami wesistimu kufanele anqume ukuthi inqubo izophendula kanjani ngemva kokuphazanyiswa kwamandla.
Impendulo yesikhundla icacile ngokulinganayo. Umyalo ovuliwe/ovaliwe awukhombisi ukuthi ibhola lifinyelele endaweni eyaliwe. Lapho ukuqinisekiswa kubalulekile, umthengi kufanele achaze ukuthi ingabe ukushintshwa komkhawulo, oxhumana naye ongumsizi noma isignali yendawo kuyadingeka yini nokuthi isistimu yokulawula izokusingatha kanjani ukungezwani phakathi komyalo nempendulo.
Linganisa Ivaluvu Ngaphakathi Kwesistimu Yokumisa Isampula
I-SINZEN ibala okuhlangene I-Electric Ball Valve yokulawula i-voltage-signal yamanzi noma izindlela zokugeleza komoya. Leyo scope eshicilelwe ihlinzeka ngendawo yokungena yomkhiqizo ewusizo, kodwa ukugunyazwa kwephrojekthi kusancika kumjikelezo owuketshezi, izimo zemvelo, imininingwane yokuxhuma kanye nezimfuneko zokulawula ezihlinzekiwe nge-oda.
Izingxenye ezizungezile zingashintsha umsebenzi we-valve. I-cooler ingase idale i-condensate, iphampu ingase ibeke ingxenye eyodwa ngaphansi kwe-vacuum, isihlungi esivinjiwe singase sandise ukucindezela okuhlukile, futhi umugqa oshisayo ungase uveze i-valve ekushiseni okuphezulu kunekhabhinethi yokuhlaziya. Umdwebo wephrojekthi kufanele ubonise indawo ye-valve ehlobene nalezi zingxenye ukuze ukuhlola kokulinganisa kusekelwe ezimeni zendawo kunokuba isimo sesitaki senqubo kuphela.
Ukuma kokufakwayo, ukufinyelela kwesevisi kanye nokwesekwa kwamashubhu nakho kuyingxenye yokubuyekezwa. I-actuator ehlangene isadinga imvume yekhebula nendawo ukuze isuswe. Amashubhu angasekelwe angalayisha umzimba we-valve encane, kuyilapho ukuhlelwa kokukhipha amanzi kungase kudinge ukugeleza kwamandla adonsela phansi kanye nephuzu eliphansi elibikezelwayo. Le mininingwane ivamise ukunquma ukuthi ukulungiswa kungaqedwa ngaphandle kokuphazamisa amathuluzi angomakhelwane.
Yakha Ukwamukela Ngobufakazi, Hhayi Izincazelo
Ikhotheshini ingase ichaze amavalvu amabili anegama elifanayo ngenkathi ihlinzeka ngezinto ezihlukene, ama-actuator namadokhumenti. Iphakheji yobufakazi kufanele yenze lowo mehluko ubonakale ngaphambi kokukhishwa kwe-oda lokuthenga.
| Kuceliwe ubufakazi | Yini okufanele iqinisekise | Inani lokuthenga |
| Idatha yomkhiqizo | Imikhawulo yengcindezi nezinga lokushisa, izinto zokwakha, ukuhlelwa kwechweba, ukuhlinzekwa kukagesi kanye nomsebenzi | Ibonisa ukuthi ukucushwa okucashuniwe kuyahambisana yini nemvilophu yokusebenza eshiwo. |

| Izintambo noma umdwebo wokulawula | I-Command logic, impendulo, isidingo samanje nokuziphatha kokulahlekelwa amandla | Ivumela ikhabhinethi yokulawula kanye nengqondo yesofthiwe ukuthi ihlolwe ngaphambi kokusebenza. |
| Irekhodi elisebenzayo nelivuzayo | Ukuvula, ukuvala, impendulo kanye nokuhlola ukuvuza okuvunyelwene ngakho | Ixhumanisa ukwamukelwa emsebenzini wangempela kunokuhlola okubonwayo kuphela. |
| Uhlu lokuchezuka | Noma yimuphi umehluko ku-RFQ, umdwebo noma ububanzi bedokhumenti eceliwe | Igcina izici ozikhethela noma ezishintshiwe ukuze zingatholakali ngemva kokulethwa. |
Lungiselela i-RFQ Ekhiqiza Izingcaphuno Eziqhathanisekayo
Ivalvu yebhola kagesi ewusizo i-RFQ ihlonza umsebenzi wevalvu, i-condensate ephakathi nendawo futhi engenzeka, ingcindezi evamile nephezulu, ingcindezi ehlukanisiwe, izinga lokushisa, ukuhlelwa kwembobo, uxhumano, izinto ezimanzi, imvamisa yomjikelezo, ugesi wokunikezela, isignali yomyalo, impendulo, isikhathi sokuhamba, indawo edingekayo yokulahlekelwa amandla, ukulindela ukuvuza, ubuningi kanye nemibhalo. Namathisela ukugeleza okufanelekile noma umdwebo weshubhu lapho indawo yevalvu ithinta ukukhethwa kokusakaza.
Cela umphakeli ngamunye ukuthi abuyisele ukucushwa okunikeziwe, izilinganiso, uhlu lwezinto ezibonakalayo, isixhumi esibonakalayo sikagesi, izixhumi ezifakiwe noma izintambo, ububanzi bokuhlola, ububanzi bedokhumenti nokunye ukuchezuka. Lokhu kudala isisekelo esivamile sobuchwepheshe ngaphambi kokuba intengo nokulethwa kuqhathaniswe. Idatha yephrojekthi ingathunyelwa nge-SINZEN's Ifomu lokubuza iphrojekthi yokuhlaziya igesi ukuze kubuyekezwe ukucushwa nokuqondanisa izilinganiso.
