Indlela yokuhlukanisa phakathi kwe-valve yokungena nokuphumayo

Namuhla, njengemboni ethuthuka ngokushesha embonini yokukhiqiza yaseShayina, izinhlobo zamavalvu nazo ziyanda, futhi ikhwalithi kanye nezidingo zezinto zokukhiqiza ama-valve nazo ziyathuthuka. I-valve * * * isetshenziswa emikhakheni ehlukahlukene, ngakho-ke abantu abaningi ngokwengeziwe bakhetha umsuka wevalvu. Kudingeka sicabangele kabanzi lapho sikhetha i-valve. Indlela yokuhlukanisa ukungenisa nokuthekelisa kwe-valve? Uyini umehluko phakathi kwe-valve yokungena nokuphumayo? Kulolu shicilelo, i-valve efana ne-valve izophendula ukukhethwa kwakho kwama-valve okungenisa kanye nokuphumayo!
1, Indlela yokuhlukanisa i-inlet ne-outlet ye-i-valve
Ukungenisa kubhekisela emikhiqizweni esuka ocwaningweni iye ekukhiqizweni ngokuhambisana ngokuqinile namazinga angaphandle. Imikhiqizo yasekhaya yakhiwe futhi yakhiwe abantu baseShayina futhi isebenzisa imikhiqizo esezingeni likazwelonke.
Ngemuva kweminyaka yemizamo, ama-valve aseShayina athole imiphumela emihle ekukhiqizeni nasekusetshenzisweni. Kodwa-ke, lapho amabhizinisi ethenga, abantu abaningi bazobeka kuqala amavalvu avela kwamanye amazwe futhi bangabi nathemba kumavalvu asekhaya.
Lapho uthenga ama-valve, abantu abaningi banaka izinga lama-valve. Indawo yokusebenza ye-valve imbi kakhulu, ngakho-ke izinga kanye nokuphila kwesevisi ye-valve kubaluleke kakhulu.
Ngenxa yokuqalwa kwangaphambi kwesikhathi kocwaningo lwamavalvu ensimbi phesheya, okokusebenza kanye nezinga le-R & D kuthuthuke kakhulu kunalawo aseShayina.
Kodwa eminyakeni yamuva nje, izinga le-valve lase-China liye lathuthukiswa kakhulu. Ngemva kwamashumi eminyaka okumuncwa nokugaya ukudla, ubuchwepheshe bokukhiqiza kanye nekhwalithi yamavalvu ensimbi eShayina kuye kwathuthukiswa kakhulu.
Ngesikhathi esifanayo, kubalulekile embonini yama-valve yaseShayina * * ukuthi iqhubeke ithuthukisa ikhwalithi yomkhiqizo kanye nokuqukethwe kobuchwepheshe, isebenzisane nabakhiqizi bamavalvu bangaphandle ukuze bathole imiphumela yokuwina, futhi ithuthuke njalo futhi ikhule enqubweni yokufunda.
2. Umehluko phakathi kwe-valve yokungena nokuphumayo
1. Ukuphila nokwethembeka
Ngo-2021, ngabamba iqhaza ocwaningweni lwabakhiqizi abakhulu bokulawula ama-valve emabhizinisini abalulekile eSinopec. Lalela imibono neziphakamiso zamabhizinisi abalulekile eSinopec kumavalvu okulawula angenisiwe asekhaya.
Igebe eliyinhloko phakathi kwama-valve okulawula asekhaya nangaphandle libonakala empilweni yesevisi nokuthembeka. Esikhathini esedlule, umjikelezo wokunakekela omkhulu wemboni ye-petrochemical yaseShayina kanye nemboni yamandla wawuyiminyaka eyi-1-1.5. Njengamanje, umjikelezo omkhulu wokunakekela unwetshiwe waba iminyaka engu-4-5.
Kwezinye izimo ezikhethekile, ukulungiswa akuvunyelwe inqobo nje uma i-valve yokulawula iqalisiwe. Uma inkinga yekhwalithi ye-valve yokulawula iholela ekuvaleni, izoletha ukulahlekelwa okungenakulinganiswa kubasebenzisi, futhi ukulahlekelwa kwansuku zonke kungafinyelela kumakhulu ezigidi noma ngisho nezigidigidi. Ngakho-ke, abasebenzisi bangathanda ukuchitha izigidi noma amashumi ezigidi zama-yuan ukuze bathenge imikhiqizo engenisiwe enempilo yesevisi ephezulu nokwethembeka.
2. Izinto eziyisisekelo kanye nezinqubo
Njengamanje, izinga lobuchwepheshe bokucubungula labakhiqizi be-valve yokulawula ekhaya liye lathuthukiswa kakhulu. Amalathe e-NC kanye nezikhungo zomshini ngokuvamile zisetshenziselwa ukucubungula, futhi okokusebenza okusetshenzwayo kucishe kufane naleyo yabakhiqizi bamavalvu bakwamanye amazwe.
Kodwa-ke, izingxenye eziningi ezibalulekile ku-valve yokulawula, kusukela entwasahlobo, i-diaphragm kuya kwendandatho yokuvala (irabha noma insimbi), inegebe elithile nemikhiqizo yangaphandle. Ikakhulukazi, kunemikhiqizo eminingana noma engaphezu kweshumi nambili phesheya, kuyilapho ngokuvamile mibili kuphela e-China.
Kukhona igebe elithile phakathi ezifuywayo ezinkulu die forgings, castings high-ingcindezi, tungsten carbide izingxenye olubunjiwe, ingxubevange eqinile olwedlula zonke, isifutho Welding ubuchwepheshe, ukushisa ukushisa ubuchwepheshe, ikakhulukazi ukusetshenziswa izinto ezikhethekile kanye nobuchwepheshe angaphandle.
3. Ukuphathwa Kwezinqolobane
Abakhiqizi bangaphandle bama-valve ochwepheshe bafaka ukubaluleka okukhulu ekuphathweni kwefayela lomsebenzisi. Ivalvu yokulawula ngayinye inesizindalwazi somsindo, okuhlanganisa amafayela aphelele njengabasebenzisi, izimo zesevisi namadijithi, usuku lwefekthri, usuku lokushayela, amarekhodi okugcinwa nokushintshwa kwezingxenye ezisele. Uma abasebenzisi beyidinga, bangadlulisela yonke idatha yomlando yemikhiqizo phakathi kwamaminithi ambalwa.
4. Isofthiwe yokukhetha
Abakhiqizi bamavalve okulawula abangochwepheshe bakwamanye amazwe (abanoFisher njengo * *) banomlando wokukhiqiza weminyaka engu-140 kusukela kwasungulwa * * * valvu yokulawula ngo-1880, futhi bathole ulwazi olucebile ekuklameni, ekukhiqizeni, ekufakeni nasekusetshenzisweni.
I-Fisher ayinayo kuphela imishini yokuhlola eqinile nokusekelwa kwezinsimbi, kodwa futhi inezinhlobo * zomkhiqizo kanye nokucaciswa kwayo. Isofthiwe yokukhetha inemisebenzi enamandla, imiyalelo ecacile nephelele, ukuze abasebenzisi bakwazi ukwamukela ngokuphelele imikhiqizo ye-Fisher.
5. Imishini yokuhlola
Imishini yaselabhorethri yabakhiqizi bamavalvu ochwepheshe bakwamanye amazwe (eneFisher as * *) iphelele kakhulu. Ilabhorethri yabo ingaqedela ukuhlolwa kwe-CV (kV), ukuhlolwa kwe-FL, ukuhlolwa kwe-CG, ukuhlolwa kwe-XT, ukuhlolwa kwe-torque eguquguqukayo, ukuhlolwa kwe-dynamic tensile, ukuhlolwa kwempilo yomjikelezo, ukuhlolwa okuguquguqukayo okuphezulu nokuphansi kwezinga lokushisa, njll.
Abakhiqizi bamavalvu okulawula asekhaya ngokuvamile banamadivaysi okuhlola ukugeleza kwamanzi kuphela, futhi iningi lawo alikakumukeli ukutholwa nokugcinwa kwedatha eguquguqukayo. Ngaphezu kwalokho, abanye abakhiqizi bamavalvu ochwepheshe abanayo ngisho nelabhorethri yokugeleza yokulinganisa ngokunembile i-coefficient yokugeleza elinganiselwe kanye nezici zokugeleza zevalvu.
6. Ukujula kwenqubo
Abakhiqizi bama-valve ochwepheshe bakwamanye amazwe banezisebenzi eziningi zokusekela ezobuchwepheshe nezesikhashana, ezijwayelene kakhulu nenqubo yokukhiqiza amandla, i-petrochemical, insimbi, usimende nezinye izimboni.
Iningi lalaba bantu benza umsebenzi ongokoqobo walezi zimboni ezingenhla. Baqonda uhlobo, ukucaciswa nokusetshenziswa kwe-valve yokulawula ekucindezelweni kwesayithi, izinga lokushisa, ingcindezi ehlukile, ukukhuhla, ukugqwala, ukugqwala, ukugqwala kwegesi kanye ne-flash, futhi baxhumana neyunithi yokuklama nomsebenzisi * * * ngaphambi kokuthenga.
Khetha * * ivalvu yokulawula efanele izimo zokusebenza komsebenzisi, bese wenza inkontileka esemthethweni ngemva kokugunyazwa umklami nomsebenzisi. Abasebenzi bosekelo lobuchwepheshe babakhiqizi bamavalvu okulawula ekhaya bacishe bashodelwa abasebenzi abanaleli zinga lekhwalithi eliphelele, okwenza abakhiqizi bangakwazi ukuxhumana nabasebenzisi.
7. Ukuqaliswa okujwayelekile
Amazinga okukhiqiza kanye nokukhiqiza ama-valve okulawula asekhaya nakwamanye amazwe ayafana ngokuyisisekelo, kodwa ama-valve okulawula angaphandle akhiqizwa ngaphezu kwesilinganiso, kuyilapho ama-valve okulawula asekhaya akhiqizwa ngemva kwezinga.
Amavalvu okulawula umoya we-GB/t4213-2008 esiwasebenzisayo njengamanje asetshenziswe iminyaka eyi-12, futhi okunye okuqukethwe akusebenzi ekukhiqizeni kwamanje nasekusetshenzisweni kwenkundla.
Lapha, ngiphakamisa ukuthi "iqembu locwaningo emkhakheni we" valve yokulawula "kufanele lihlele abasebenzi abafanelekile ukuze babuyekeze izinga le-GB / t4213-2008 valvu yokulawula umoya esikhathini esizayo esiseduze.
