Izimbangela zei-valve yebholaukuvuza kwangaphakathi, izimbangela zokuvuza kwangaphakathi kwe-valve ngesikhathi sokwakhiwa:

(1) ukuthutha nokuphakamisa okungafanele kubangela umonakalo wonke wevalvu, okuholela ekuvuzeni kwevalvu;

(2) Lapho uphuma efektri, umfutho wamanzi awomiswa futhi ukwelapha i-valve nge-anticorrosive, okubangela ukugqwala kwendawo yokuvala nokuvuza kwangaphakathi;

(3) isivikelo sendawo yokwakha asikho, iziphetho zamavalvu azifakelwe amapuleti angaboni, amanzi emvula, isihlabathi nokunye ukungcola esihlalweni, okuholela ekuvuzeni;

(4) lapho ufaka, awekho amafutha afakwa esihlalweni sevalvu, okuholela ekungcoleni ngemuva kwesihlalo sevalvu, noma ukushisela okubangelwa ukuvuza kwangaphakathi;

(5) I-valve ayifakiwe endaweni evulekile egcwele, edala umonakalo ebhola, ekushiseni, uma i-valve ingekho endaweni evulekile egcwele, i-spatter ye-welding izodala umonakalo ebhola, lapho ibhola eline-welding spatter ku-switch lizophinde libangele ukulimala esihlalweni se-valve, okuholela ekuvuzeni kwangaphakathi;

(6) i-slag yokushisela nezinye izinsalela zokwakha ezibangelwa ukuklwebheka kwendawo evalekile;

Ifekthri noma umkhawulo wesikhathi sokufaka awunembile okubangelwa ukuvuza, uma umkhono we-stem drive noma ezinye izesekeli kanye nokuhlanganiswa kwe-Angle dislocation, i-valve izovuza.

Izimbangela zokuvuza kwangaphakathi kwe-valve ngesikhathi sokusebenza:

(1) Isizathu esivame kakhulu ukuthi umphathi wokusebenza akaligcini ivalvu ngokucabangela izindleko zokuyilungisa ezimba eqolo, noma akenzi ukugcinwa kokuvimbela ivalvu ngenxa yokuntuleka kokuphathwa kwamavalvu esayensi nezindlela zokuwalungisa, okuholela ekuhlulekeni kwemishini kusenesikhathi;

(2) Ukuvuza kwangaphakathi okubangelwa ukusebenza okungalungile noma ukwehluleka ukugcina ngokuhambisana nezinqubo zokulondoloza;

(3) Ngesikhathi sokusebenza okuvamile, izinsalela zokwakha ziklwebha indawo yokuvala, okuholela ekuvuzeni kwangaphakathi;

(4) ukugetshengwa kwengulube ngendlela engafanele kudale umonakalo endaweni evalekile okuholela ekuvuzeni kwangaphakathi;

(5) ukugcinwa isikhathi eside noma ukungasebenzi kwevalvu, okuholela ekutheni isihlalo sevalvu ivalwe kanye nebhola, lapho uvula futhi uvala ivalvu kubangele ukulimala kokuvala ukuze kuvuze kwangaphakathi;

(6) I-valve switch ayikho endaweni ukuze ibangele ukuvuza kwangaphakathi, noma yikuphii-valve yebholakungakhathaliseki ukuthi ivuliwe noma ivaliwe, ngokuvamile ukutsheka okungu-2° ~ 3° kungase kubangele ukuvuza;

(7) ububanzi obuningi obukhului-valve yebholaikakhulukazi i-stem stop block, uma ukusetshenziswa kwesikhathi eside, ngenxa yokugqwala nezinye izizathu ku-stem kanye ne-stem stop stop block izoqongelela ukugqwala, uthuli, upende nezinye izinhlobo ezihlukahlukene, lezi zihlukahlukene zizobangela ukuthi i-valve ingakwazi ukujikeleza endaweni futhi ibangele ukuvuza - uma i-valve ingcwatshwa, Ukwandisa i-stem kuzodala futhi kulahle ukugqwala okwengeziwe nokungcola okuvimbela ukugqwala kwe-valve kanye nokungcola okuvimbela indawo ye-valve ejikelezayo.

(8) I-actuator jikelele nayo inomkhawulo, uma imbangela yesikhathi eside ukugqwala, ukuqina kwamafutha noma ukuxegiswa kwebholithi yomkhawulo kuzokwenza umkhawulo awunembile, okuholela ekuvuzeni;

(9) Indawo yevalvu ye-actuator kagesi isethwe ngaphambili, futhi ayikho endaweni yokuthi ibangele ukuvuza kwangaphakathi; Abahambele umcimbi ukuntuleka kokunakekelwa nokugcinwa ngezikhathi ezithile, okuholela ekutheni amafutha avale omile futhi aqine, ukunqwabelana kwamafutha ovala omile esihlalweni esinwebekayo se-valve, kuvimbela ukunyakaza kwesihlalo se-valve, okuholela ekuhlulekeni kokuvala.

I-valve yebholaizinqubo zokwelapha ukuvuza

(1) Okokuqala hlola umkhawulo we-valve ukuze ubone ukuthi ukuvuza kwangaphakathi kwe-valve kungaxazululwa ngokulungisa umkhawulo.

(2) Qala ngokujova inani elithile lamafutha ukuze ubone ukuthi lingakwazi yini ukumisa ukuvuza, khona-ke ijubane lomjovo kufanele lihambe kancane, futhi ubheke uguquko lwesikhombi segeji yokucindezela endaweni yokukhipha isibhamu samafutha ukuze kunqunywe ukuvuza kwevalvu.

(3) uma ukuvuza ayikwazi ukumiswa, kungenzeka ukuthi umjovo zakuqala of sealing fat lukhuni noma uphawu umonakalo surface okubangelwa ukuvuza. Kunconywa ukuthi uketshezi lokuhlanza i-valve lujovwe ngalesi sikhathi ukuhlanza indawo yokuvala ye-valve kanye nesihlalo se-valve. Ngokuvamile ecwiliswe okungenani isigamu sehora, uma kunesidingo, kungaba cwilisa amahora ambalwa noma ngisho izinsuku ezimbalwa, ukuze welapheke ngemva konke zincibilike bese wenza isinyathelo esilandelayo ukwelashwa. Kuyinto efiselekayo ukuvula nokuvala i-valve ehambayo izikhathi eziningana phakathi nale nqubo.

(4) faka kabusha amafutha, uvule futhi uvale ivalvu ngezikhathi ezithile, futhi ukhiphe ukungcola egumbini elingemuva lesihlalo nangaphezulu.

(5) hlola endaweni evaliwe egcwele, uma kusekhona ukuvuza, kufanele ijovwe ukuze kuqiniswe izinga lamafutha okufaka uphawu, kuyilapho uvula igumbi le-valve ukuze likhiphe umoya, okungase kuveze umehluko omkhulu wengcindezi, uphawu lokusiza, ngaphansi kwezimo ezijwayelekile, ngomjovo wokuqinisa izinga lokuvuza kwamafutha angaqedwa.

Uma kusekhona ukuvuza, lungisa noma shintsha ivalvu.
