Izimbangela zokuvuza kwangaphakathi kwe-Ball Valve kanye nezinqubo zokwelashwa zokuvuza kwangaphakathi

Izimbangela zokuvuza kwangaphakathi kwama-valve ebhola

1) Izizathu zokuvuza kwangaphakathi kwe-valve ngesikhathi sokwakha:

① Ukuhamba ngendlela engafanele kanye nokuphakanyiswa kubangela ukulimala okuphelele kwe-valve, okuholela ekuvuzeni kwangaphakathi kwe-valve;② Lapho uphuma efektri, i-valve ayizange yomiswe futhi iphathwe nge-anti-corrosion ngemva kokufakwa kwengcindezi yamanzi, okwenza indawo yokuvala igle futhi yakhe ukuvuza kwangaphakathi;③ Ukuvikelwa kwendawo yokwakha kwakungekho endaweni, futhi i-valve Awekho amapuleti ayimpumputhe afakwe kuzo zombili iziphetho, futhi ukungcola okunjengamanzi emvula nesihlabathi kungena esihlalweni se-valve, okubangela ukuvuza;④ Ngesikhathi sokufakwa, awekho amafutha afakwa esihlalweni sevalvu, okwenza ukungcola kungene ngemuva kwesihlalo sevalvu, noma ukuvuza kwangaphakathi okubangelwa ukusha ngesikhathi sokushisela;⑤ I-Valve Ayifakiwe endaweni evulekile ngokugcwele, okuzodala umonakalo ebhola.Ngesikhathi sokushisela, uma i-valve ingekho endaweni evulekile ngokugcwele, i-spatter ye-welding izodala umonakalo ebhola.Lapho ibhola eline-welding spatter livuliwe futhi livaliwe, isihlalo se-valve sizophinde sonakaliswe, ngaleyo ndlela Ibangele ukuvuza kwangaphakathi;⑥ I-slag yokushisela nezinye izinsalela zokwakha kubangela imihuzuko endaweni yokuvala;⑦ Indawo yomkhawulo engalungile ngesikhathi sokulethwa noma ukufakwa kubangela ukuvuza, uma umkhono we-valve stem drive noma ezinye izesekeli zihlanganiswe nge-engeli engalungile, i-valve izovuza.

2) Izizathu zokuvuza kwangaphakathi kwe-valve ngesikhathi sokusebenza:

① Isizathu esivame kakhulu ukuthi umphathi wokusebenza akaligcini i-valve ngokucabangela izindleko zokulungisa ezibizayo, noma akanakho ukuphathwa kwamavalvu esayensi nezindlela zokunakekela ukuvimbela ukugcinwa kokuvimbela i-valve, okuholela ekuhlulekeni kwangaphambi kwesikhathi kwezisetshenziswa;② Ukusebenza ngendlela engafanele noma ukuntuleka Kokulungisa ngokwezinqubo zokulungisa ukuze kubangele ukuvuza kwangaphakathi;③ Ngesikhathi sokusebenza okuvamile, izinsalela zokwakha ziklwebha indawo yokuvala, okuholela ekuvuzeni kwangaphakathi;④ Ingulube engafanele idala umonakalo endaweni evalekile futhi ibangele ukuvuza kwangaphakathi;Isihlalo kanye nebhola kukhiyiwe, okubangela ukulimala kophawu kanye nokuvuza kwangaphakathi lapho i-valve ivulwa futhi ivaliwe;⑥ I-valve switch ayikho endaweni, okubangela ukuvuza kwangaphakathi.Noma iyiphi i-valve yebhola, kungakhathaliseki ukuthi ivuliwe noma ivaliwe kuphi, ivame ukutsheka ngo-2° ukuya ku-3°, okungase kubangele ukuvuza;⑦ Amavalvu amaningi anobubanzi obukhulu angase abangele ukuvuza.Ama-valve amaningi ebhola anezivalo ze-valve stem.Uma zisetshenziswa isikhathi eside, ukugqwala, uthuli, upende nezinye izinsalela zizonqwabelana phakathi kwesiqu se-valve kanye nesivalo se-valve ngenxa yokugqwala nezinye izizathu.Le mfucumfucu izovimbela i-valve ukuthi ingazungezi endaweni.Imbangela yokuvuza - uma i-valve igqitshiwe, ukunwetshwa kwesiqu se-valve kuzokhiqiza futhi kwehlise ukugqwala nokungcola okwengeziwe ukuze kuvinjwe ibhola le-valve ukuthi lingazungezi endaweni, okubangela ukuthi i-valve ivuze.Ukuqina noma ukuxegiswa kwebhawodi yomkhawulo kuzokwenza umkhawulo unganembile, okuholela ekuvuzeni kwangaphakathi;⑨ Indawo yevalvu ye-actuator kagesi isethwe ngaphambili, futhi ayivalwanga endaweni, okuholela ekuvuzeni kwangaphakathi;⑩ Ukuntuleka kokugcinwa nokugcinwa ngezikhathi ezithile kuzobangela ukuba amafutha okufaka uphawu ome , Amafutha okufaka uphawu aqinile futhi omisiwe aqoqana ngemuva kwesihlalo se-valve enwebekayo, avimbele ukunyakaza kwesihlalo se-valve futhi abangele uphawu lwehluleke.

I-valve yebhola ye-shaft engashintshi ivame ukusetshenziswa kumapayipi egesi yemvelo.Indlela yokuhlola evamile yilena: vula i-valve endaweni evuleke ngokugcwele noma evaleke ngokugcwele, bese uhlola ukuthi ingabe kukhona ukuvuza ngokuphuma kwe-valve body drain nozzle.Uma ingakhanywa ngokuhlanzekile, uphawu luhle.Uma kukhona ukukhishwa kwengcindezi njalo, kungacatshangwa ukuthi i-valve ivuza, futhi i-valve kufanele iphathwe ngokufanele.

Inqubo yokwelapha yokuvuza kwangaphakathi kwe-valve yebhola yegesi yemvelo

① Okokuqala hlola umkhawulo we-valve ukuze ubone ukuthi ukuvuza kwangaphakathi kwe-valve kungaxazululwa yini ngokulungisa umkhawulo.②Faka inani elithile lamafutha kuqala ukuze ubone ukuthi lingakwazi yini ukumisa ukuvuza.Ngalesi sikhathi, isivinini somjovo kumele sihambe kancane.Ngesikhathi esifanayo, bheka ukuguqulwa kwesikhombisi segeji yokucindezela ekuphumeni kwesibhamu somjovo wamafutha ukuze unqume ukuvuza kwangaphakathi kwe-valve.③ Uma ukuvuza kungakwazi ukumiswa, ukuvuza kwangaphakathi kungase kubangelwe ukuqina kwegrisi yokuvala ejovwe ekuqaleni noma ukonakala kwendawo yokuvala.Kunconywa ukujova uketshezi lokuhlanza i-valve ngalesi sikhathi ukuze uhlanze indawo yokuvala kanye nesihlalo se-valve ye-valve.Ngokuvamile, ifakwe okungenani isigamu sehora, uma kunesidingo, ingacwiliswa amahora ambalwa noma ngisho nezinsuku ezimbalwa.Kungcono ukuvula nokuvala i-valve esebenzayo izikhathi eziningana phakathi nale nqubo.④ Faka kabusha amafutha, vula futhi uvale ivalvu ngezikhathi ezithile, futhi ukhiphe ukungcola ngemuva kwesihlalo sevalvu kanye nendawo yokuvala.⑤ Hlola endaweni evalwe ngokugcwele.Uma kusekhona ukuvuza, jova igrisi yokuvala eqinisiwe, futhi uvule imbobo yevalvu ukuze kuphume umoya, okungadala umehluko omkhulu wokucindezela nokusiza ukuvala.Ngokuvamile, ngokujova i-grease eqinisiwe yokuvala i-Endoleak ingaqedwa.⑥ Uma kusekhona ukuvuza kwangaphakathi, lungisa noma shintsha ivalvu.
