Umupira wuzuye Weld

UMUPIRA WIZA Wuzuye

1.Bow-out gihamya
Mu ntumbero yo kubuza uruti kuguruka bigatuma izamuka ridasanzwe ryumuvuduko wimbere wa valve, urutugu rushyirwa mugice cyo hepfo cyuruti. Byongeye kandi, kugirango hirindwe kumeneka bituruka ku gutwikwa kwipakira ryashizweho muruti umuriro, gusunika byashyizwe kumwanya wo guhuza urutugu mugice cyo hepfo cyuruti na valve.Noneho hashyizweho intebe ya kashe ihindagurika izarinda kumeneka no kwirinda impanuka.

2.Anti-fire igishushanyo mbonera
Iyo umupira wa trunnion ukoreshwa mubisanzwe, ushyizweho kashe hamwe nintebe yumupira, kugumana intebe bifunzwe na O-impeta numubiri, ibi biroroshye gufunga kandi bifunze neza.Iyo intebe na O-impeta byatwitse, uwagumanye intebe numubiri bizashyirwaho kashe na grafite yagutse.Ibyo bikorwa bigamije kurwanya umuriro.

3.Ibikoresho bya Anti-static
Mu rwego rwo gukumira ubushyamirane hagati yumupira, uruti na PTFE bitanga amashanyarazi ahamye ashobora gucana umuriro n’ibisasu bitera impanuka, muri iyi valve yumupira, isoko-itwara static ishyirwa hagati yumuti numupira, uruti numubiri. .Iyo mashanyarazi ihamye ikorwa kubutaka kandi umutekano wa sisitemu urinzwe.

4.Ubusa kumubiri byubatswe bifunze
Umwanya uhuza umubiri wa valve na bonnet ufunzwe kabiri na gasketi na O-ring, kuriyi shingiro, ibintu nkumuriro, ubushyuhe bwinshi, guhungabana no gufungura kutaringaniye cyangwa gufunga umuriro byose ntibishobora gutera gusohoka hanze.

5.Gabanya urumuri rukora
Kwishyiriraho amavuta yashyizweho ashyirwa muguhuza uruti, bikaviramo kwihanganira kwambara, fiexibilité yimikorere na torque nkeya.

6. Guhagarika kabiri no kuva amaraso (DBB)
Iyo umupira wuzuye ufunguye cyangwa ufunze, ibintu byohereza mumyanya yo hagati yumubiri birashobora kurekurwa nibikoresho byamazi hamwe nubusa. Byongeye kandi, umuvuduko mwinshi uremereye mumyanya yo hagati ya valve urashobora kurekurwa kumuvuduko muke ukarangira wicaye wenyine. .

7.Gufunga byihutirwa
Imyobo yo gutera inshinge yarateguwe kandi indangantego yo gutera inshinge zishyirwa ahantu hashyizweho stem / cap hamwe ninkunga yumubiri ya valve kuruhande.Iyo gufunga igiti cyangwa intebe byangiritse kugirango bitume kumeneka, uruganda rushobora gukoreshwa mugukora kashe ya kabiri.Ibihishe cheque valve yashyizwe muruhande rwa buri cyuma cyo gutera inshinge kugirango irinde ibivamo gusohoka bitewe nigikorwa cyibikoresho byohereza. Hejuru yikibumbano cyo guteramo ibice ni umuhuza kugirango uhuze byihuse nimbunda yo gutera inshinge.

8.Uruti rwagutse
Kubutaka bwubatswe munsi yubutaka, uruti rushobora kuramba kandi kugirango byorohereze imikorere ijyanye no gutera inshinge hamwe na valve ya drainage irashobora kwagurwa hejuru ya valve.

9.Umubiri wimyanya yumubiri
Iyo umuvuduko wumubiri uzamutse muburyo budasanzwe nkibintu bidahindagurika, trunnion ball valve intebe yo hepfo izasunikwa numuvuduko udasanzwe, kandi kurekura umuvuduko udasanzwe uhita, ntabwo byangiza gufunga intebe yo hejuru.

10. Ubwoko butandukanye bwo gutwara
Padiri yo hejuru ya valve yateguwe ukurikije ISO 5211, yorohereza guhuza no guhana abashoferi batandukanye. Ubwoko busanzwe bwo gutwara ni intoki, amashanyarazi, pneumatike na pneumatike / hydraulic
