Ukusombulula njani ukuvuza kwevalvu?

1. Khangela unobangela wokuvuza

Okokuqala, kuyimfuneko ukuxilonga ngokuchanekileyo isizathu sokuvuza. Ukuvuza kunokubangelwa zizinto ezahlukeneyo, ezinje ngomgangatho wokutywina, ukuwohloka kwemathiriyeli, ukufakela okungafanelekanga, iimpazamo zabasebenzisi, okanye ukudleka kwemithombo yeendaba. Umthombo wokuvuza unokuchazwa ngokukhawuleza ngokusebenzisa izixhobo zokuhlola kunye neendlela, ezifana ne-ultrasonic leak detectors, ukuhlolwa okubonakalayo, kunye neemvavanyo zoxinzelelo, ukubonelela ngesiseko esiqinileyo sokulungiswa okulandelayo.

Okwesibini, isisombululo seendawo ezahlukeneyo zokuvuza

1. Isiqwenga sokuvala siyawa kwaye sibangele ukuvuza

Izizathu: Ukusebenza kakubi kubangela ukuba iindawo zokuvala zifakwe okanye zigqithise iziko eliphezulu lokufa, kwaye uxhulumaniso lonakaliswe kwaye luphukile; Izinto eziphathekayo zomdibaniso okhethiweyo ziphosakele, kwaye azikwazi ukumelana ne-corrosion ye-medium kunye nokugqoka koomatshini.

Isisombululo: Sebenzisa ivalve ngokuchanekileyo ukunqanda amandla agqithisileyo abangela ukuba iindawo zokuvala zixinge okanye zonakaliswe; Jonga rhoqo ukuba uxhulumaniso phakathi kokuvala kunye ne-valve stem luqinile, kwaye utshintshe uxhumano ngexesha ukuba kukho ukubola okanye ukunxiba; Khetha izinto eziphathekayo zekhonkco kunye nokuchasana kakuhle kwe-corrosion kunye nokumelana nokunxiba.

2. Ukuvuza ekudibaneni komsesane wokutywina

Isizathu: Umsesane wokutywina awusongwanga ngokuqinileyo; Umgangatho wokuwelda ombi phakathi komsesane wokutywina kunye nomzimba; Imisonto yokutywina kunye nezikrufu zikhululekile okanye zidliwe.

Isisombululo: Sebenzisa i-adhesive ukulungisa indawo yokugubungela umsesane wokutywina; Lungisa kwaye udibanise kwakhona iziphene ze-welding; Ukutshintshwa ngexesha elifanelekileyo leentambo kunye nezikrufu ezonakeleyo okanye ezonakalisiweyo; Phinda weld isidibaniso setywina ngokweenkcukacha.

3. Ukuvuza komzimba wevalvu kunye nebhonethi

Isizathu: Umgangatho wokuphosa we-iron castings awuphezulu, kwaye kukho iziphene ezifana nemingxuma yesanti, izicubu ezikhululekile, kunye ne-slag inclusions; iintsuku emkhenkceni eziqhekekile; I-welding engafanelekanga, eneziphene ezifana nokufakwa kwe-slag, i-unwelding, i-stress cracks, njl.; Ivalve yonakala emva kokubethwa yinto enzima.

Isisombululo: Phucula umgangatho wokuphosa kwaye wenze uvavanyo lwamandla phambi kofakelo; Ivalve enobushushu obuphantsi kufuneka ifakwe i-insulated okanye ixutywe nobushushu, kwaye ivalve engasetyenziswayo kufuneka ikhutshwe ngamanzi amileyo; I-Weld ngokuhambelana neenkqubo zokusebenza kwe-welding, kwaye uqhube ukufumanisa iimpazamo kunye novavanyo lwamandla; Akuvumelekanga ukutyhala kunye nokubeka izinto ezinzima kwivalve, kwaye ugweme ukubetha intsimbi etyhidiweyo kunye neevalvu ezingezizo ezentsimbi ngehamile yesandla.

4. Ukuvuza kwendawo yokutywina

Isizathu: ukugaya okungalinganiyo kwendawo yokutywina; Ukudibanisa phakathi kwesiqu kunye nokuvalwa kujinga, kungafanelekanga okanye kugugile; iziqu ezigobileyo okanye ezidityanisiweyo; Ukukhetha okungafanelekanga kwezinto ezingaphezulu zokutywinwa.

Isisombululo: Ukukhethwa ngokuchanekileyo kwezinto ze-gasket kunye nohlobo ngokwemiqathango yokusebenza; Lungisa ngokucophelela i-valve ukuqinisekisa ukusebenza kakuhle; Qinisa ibholiti ngokulinganayo kunye ne-symmetrically, kwaye usebenzise i-torque wrench ukuqinisekisa ukuba ukulayisha kwangaphambili kuyahlangabezana neemfuno; Ukulungiswa, ukugaya kunye nokuhlolwa kombala weendawo zokutywina ezizinzileyo ukuqinisekisa ukuba ziyahlangabezana neemfuno ezifanelekileyo; Nika ingqalelo ekucoceni xa ufaka i-gasket ukuze ugweme i-gasket ewela phantsi.

5. Ukuvuza kwi-filler

Isizathu: ukhetho olungafanelekanga lokuzalisa; Ukufakela ukupakisha okungalunganga; ukuguga kweefayili; Ukuchaneka kwesiqu akuphezulu; Amadlala, iibholiti kunye nezinye iindawo zonakele.

Isisombululo: Khetha izinto ezifanelekileyo zokupakisha kwaye uthayiphe ngokweemeko zokusebenza; Ukufakwa ngokufanelekileyo kokupakisha ngokweenkcukacha; Faka endaweni yokuguga kunye nezizalisi ezonakalisiweyo ngexesha elifanelekileyo; ukulungisa, ukulungisa okanye ukutshintsha iziqu ezigobileyo, ezigugileyo; Iingqungquthela ezonakalisiweyo, iibholiti kunye nezinye izinto kufuneka zilungiswe okanye zitshintshwe ngexesha; Landela iinkqubo zokusebenza kwaye usebenzise i-valve ngesantya esingaguqukiyo kunye namandla aqhelekileyo.

3. Amanyathelo okuthintela

1. Ukuhlolwa kunye nokugcinwa rhoqo: Yenza isicwangciso sokulondoloza esifanelekileyo ngokuphindaphindiweyo kokusetyenziswa kwevalve kunye nendawo yokusebenza. Kubandakanya ukucoca imiphezulu yangaphakathi nangaphandle yevalvu, ukujonga ukuba iziqhoboshi zikhululekile na, ukuthambisa iindawo zothumelo, njl.njl. Ngokulungiswa kwenzululwazi, iingxaki ezinokuthi zifunyanwe kwaye zisingathwe kwangethuba ukuze kwandiswe ubomi benkonzo yesivalo.

2. Khetha iivalve ezikumgangatho ophezulu: Ukunciphisa ngokusisiseko umngcipheko wokuvuza kwevalve, kuyimfuneko ukukhetha iimveliso ezikumgangatho ophezulu. Ukusuka ekukhethweni kwezinto, uyilo lwesakhiwo ukuya kwinkqubo yokuvelisa, iimveliso zevalve zilawulwa ngokungqongqo ukuze kuqinisekiswe ukusebenza kakuhle. Ukusebenza ngokuchanekileyo kunye nofakelo: Landela iinkqubo zokusebenza kwaye usebenzise ivalve ngokuchanekileyo. Ngethuba lenkqubo yokufakela, qaphela indawo yokufakela kunye nesikhokelo se-valve ukuqinisekisa ukuba i-valve inokuvulwa kwaye ivalwe ngokuqhelekileyo. Kwangaxeshanye, kuphephe ukusebenzisa amandla agqithisileyo kwivalve okanye ukubetha ivalve.

Ukuba kukhoivalve ehleli ibhabhathane ehleliyo,ivalve yesango, ivalve yokukhangela, i-Y-strainer, ungaqhagamshelana nayoIvalve yeTWS.
