Isingeniso:

Ekusetshenzisweni kwansuku zonke kwabasebenzisi be-large diameter butterfly valve, sivame ukukhombisa inkinga, okungukuthi, i-large diameter butterfly valve esetshenziselwa ukucindezela okuhlukile imidiya enkulu, njengomusi, amanzi anomfutho ophezulu kanye neminye imisebenzi ecindezelwe, kuvame ukuba nzima kakhulu ukuyivala, kungakhathaliseki ukuthi kunzima kangakanani ukuyivala, kuhlale kutholakala ukuthi kuzoba khona ukuvuza, kunzima ukuyivala ngokuqinile, okuholela enkingeni ebangelwa ukwakheka kwe-valve kanye nomkhawulo womuntu wezinga le-torque yokukhipha akwanele.

Ukuhlaziywa kwezizathu zobunzima bokushintsha ama-valve amakhulu

Amandla okukhipha amandla ajwayelekile omkhawulo ovundlile womuntu omdala angama-60-90kg, kuye ngobukhulu bomzimba obuhlukene.

Indlela ejwayelekile yokugeleza kwevalvu yebhabhathane yenzelwe ukuba ibe phansi ngaphakathi naphezulu, lapho umuntu evala ivalvu, umzimba womuntu usunduza isondo lesandla ngokuvundlile ukuze lijikeleze, ukuze i-valve flap iye phansi ukuze ifinyelele ukuvalwa, okudingekayo ukuze kunqotshwe inhlanganisela yamandla amathathu, okungukuthi:

1) Ukusunduza okuphezulu kwe-Axial Fa;

2) ukupakisha kanye namandla okungqubuzana kwesiqu Fb;

3) Ukungqubuzana kokuxhumana kwe-stem kanye ne-valve core Fc

Ingqikithi ye-torque ingu-∑M=(Fa+Fb+Fc)R

Njengoba kungabonakala, uma i-caliber inkulu, kulapho amandla okusunduza e-axial eba makhulu khona, uma eseduze nesimo esivaliwe, amandla okusunduza e-axial acishe asondele kakhulu ekucindezelweni kwangempela kwenethiwekhi yamapayipi (ngenxa yokuvalwa kwe-P1-P2 ≈ P1, P2 = 0)

Uma kusetshenziswa ivalvu yebhabhathane ye-DN200 caliber epayipini lomusi le-10bar, kuphela i-axial thrust yokuqala yokuvala i-Fa = 10 × πr2 = 3140kg, kanye namandla okujikeleza avundlile adingekayo ukuze kuvalwe aseduze nomkhawulo wamandla okujikeleza avundlile angaphuma emzimbeni womuntu ojwayelekile, ngakho-ke kunzima kakhulu ngomuntu ukuvala ngokuphelele ivalvu ngaphansi kwezimo zokusebenza ezinjalo.

Vele ezinye izimboni zincoma ukufaka lolu hlobo lwe-valve ngokuphambene, okuxazulula inkinga yobunzima bokuvala, kodwa-ke kuvela inkinga yobunzima bokuvula ngemva kokuvala.

 

Umkhiqizi we-flange enkulu kagesi ye-butterfly valve Tianjin Zhongfa Valve-ZFA uqeda ubuchwepheshe bomnyango, i-flange enkulu kagesi ye-butterfly valve enezizathu zokuvuza zinezimo ezahlukene ngokwezinhlelo ezahlukene, kunezizathu ezahlukene, okulandelayo ukuhlaziya amacala amabili:

 

Okokuqala, isikhathi sokwakhiwa okubangelwa ububanzi obukhulu be-flange kagesi ye-butterfly valve ukuvuza kwangaphakathi kwezizathu: 

1. Ukuthutha nokuphakamisa okungafanele okubangelwa umonakalo ojwayelekile we-lange kagesi ye-butterfly valve, ngaleyo ndlela kubangele ukuvuza kwe-lange kagesi ye-butterfly valve;

② ifektri, ngemva kokucindezela kwamanzi akuzange kudlale ububanzi obukhulu be-flange kagesi, i-valve ye-butterfly yomiswa futhi iphathwe ngokulwa nokugqwala, okuholela ekwakhekeni kokuvuza kwangaphakathi kokugqwala kokubekwa uphawu;

③ ukuvikelwa kwendawo yokwakha akusebenzi, i-valve enkulu ye-flange kagesi enobubanzi obukhulu ayifakiwe kuzo zombili iziphetho zokungcola okungabonakali, imvula, isihlabathi nokunye esihlalweni se-valve, okuholela ekuvuzeni;

④ Ngesikhathi sokufakwa, akukho grisi efakwa esihlalweni sevalvu, okuholela ekungcoleni okungena ngemuva kwesihlalo sevalvu, noma ukusha okubangelwa ukuvuza kwangaphakathi ngesikhathi sokushisela;

⑤ Ivalvu ayifakwanga endaweni evulekile ngokuphelele, okubangela umonakalo ebholeni. Ngesikhathi sokushisela, uma ivalvu ingekho endaweni evulekile ngokuphelele, i-welding spatter izobangela umonakalo ebholeni, futhi uma ibhola eline-welding spatter livuliwe futhi livaliwe, lizobangela umonakalo omkhulu esihlalweni sevalvu, ngaleyo ndlela kuholele ekuvuza kwangaphakathi;

⑥ Ukushisela i-slag kanye nezinye izinsalela zokwakha ezibangelwa ukuklwebheka kobuso bokuvala;

Isikhathi sokufaka noma sokufaka asilungile ngenxa yokuvuza, uma i-valve stem drive sleeve noma ezinye izesekeli kanye ne-assembling angle yayo ingalingani, i-large diameter electric flange butterfly valve izovuza.

 

Okwesibili, isikhathi sokusebenza esibangelwa ukuvuza okukhulu kwe-flange kagesi ye-butterfly valve:

① Isizathu esivame kakhulu ukuthi umphathi wemisebenzi ucabangela izindleko zokulungisa ezibizayo ze-large diameter electric flange butterfly valve ayenzi ukulungiswa, noma ukuntuleka kwezindlela zesayensi zokuphatha nezindlela zokulungisa i-large diameter electric flange butterfly valve ayenzi ukulungiswa kokuvimbela, okuholela ekulimaleni kwemishini kusenesikhathi;

② ukusebenza okungafanele noma ukungahambisani nezinqubo zokulungisa ezibangelwa ukuvuza kwangaphakathi;

③ Ekusebenzeni okuvamile, izinsalela zokwakha ziyaklwebha indawo yokuvala, okuholela ekuvuza kwangaphakathi;

④ Ukuhlanzwa kwamapayipi ngendlela engafanele kubangela umonakalo ebusweni bokuvala okuholela ekuvuza kwangaphakathi;

⑤ Ukungalungi isikhathi eside noma ukungasebenzi kwevalvu yebhathane kagesi enobubanzi obukhulu, okuholela ekubambeni kwesihlalo sevalvu kanye nokubamba ibhola, okubangela umonakalo wokuvala lapho kushintsha ivalvu yebhathane kagesi enobubanzi obukhulu ukuze kwakheke ukuvuza kwangaphakathi;

⑥ inkinobho ye-valve ye-flange kagesi enobubanzi obukhulu ayitholakali ukuze ibangele ukuvuza kwangaphakathi, noma iyiphi i-valve ye-flange kagesi enobubanzi obukhulu kungakhathaliseki ukuthi ivula noma ivala kanjani, ngokuvamile ukuthambekela okungu-2 ° ~ 3 ° kungabangela ukuvuza;

⑦ Amavalvu amaningi e-flange kagesi amakhulu anobubanzi obukhulu ane-block yokumisa isiqu, uma esetshenziswa isikhathi eside, ngenxa yokugqwala nokugqwala kanye nezinye izizathu phakathi kwe-stem kanye ne-stem stop block kuzoqongelela ukugqwala, uthuli, upende kanye nezinye izinsalela, lezi zinsalela zizobangela ukuthi i-flange kagesi enkulu inobubanzi obukhulu i-valve ye-butterfly ayikwazi ukujikeleziswa endaweni yayo futhi ibangele ukuvuza - uma i-flange kagesi enkulu inobubanzi obukhulu ingcwatshwe, ukwelula isiqu se-valve kuzokhiqiza futhi kwehle ukugqwala okwengeziwe kanye nokungcola kuphazamisa ukujikeleza kwebhola le-valve endaweni, okuholela ekuvuthweni kwe-valve ye-butterfly kagesi enobubanzi obukhulu.

⑧ i-actuator ejwayelekile nayo inqunyelwe, uma imbangela yokugqwala kwesikhathi eside, ukuqina kwamafutha noma amabhawodi omkhawulo ekhululeka kuzokwenza umkhawulo unganembile, okuholela ekuvuza kwangaphakathi;

⑨ isikhundla se-valve ye-actuator kagesi ebekwe phambili, engahlobene nokuba khona endaweni okubangela ukuvuza kwangaphakathi;

⑩ ukuntuleka kokugcinwa nokugcinwa njalo, okuholela ekuvaleni amafutha amafutha okuvala owomile, oqinile, owomile aqoqana esihlalweni se-valve elastic, okuvimbela ukunyakaza kwesihlalo se-valve, okuholela ekwehlulekeni kokuvalwa.

I-ZFA Valve Factory inamaqembu e-QC ochwepheshe ukuqinisekisa ukuthi ivalvu ngayinye yefektri ngaphakathi nangaphandle kwayo kuphilile. Ngesikhathi esifanayo, sinamaqembu obuchwepheshe obuchwepheshile kanye namaqembu asebenza ngemuva kokuthengisa ukusiza amakhasimende ukuxazulula izinkinga ezahlukahlukene ahlangabezana nazo ngesikhathi sokufakwa nokusetshenziswa.
