Kugenzura mbere yo gushiraho valve

Reba neza niba moderi ya valve nibisobanuro byujuje ibisabwa byo gushushanya.

② Reba niba igiti cya valve na disiki byoroshye mugukingura, kandi niba bifatanye cyangwa bigoramye.

③ Reba niba valve yangiritse kandi niba insinga za valve zifite urudodo zigororotse kandi zidahwitse.

④ Reba niba isano iri hagati yintebe ya valve numubiri wa valve ihamye, ihuriro riri hagati ya disiki ya valve nintebe ya valve, igifuniko cya valve numubiri wa valve, hamwe nigiti cya valve na disiki ya valve.

⑤ Reba niba gasike ya valve, gupakira hamwe na feri (bolts) bikwiranye nibisabwa mumiterere yimikorere ikora.

⑥ Umuvuduko ugabanya indangagaciro zishaje cyangwa zasigaye igihe kinini zigomba gusenywa, kandi umukungugu, umucanga n’ibindi bisigazwa bigomba guhanagurwa n’amazi.

Kuraho igifuniko cyo gufunga icyambu hanyuma urebe urugero rwa kashe.Disiki ya valve igomba gufungwa cyane.

Ikizamini cyumuvuduko

Umuvuduko muke, umuvuduko ukabije hamwe numuvuduko mwinshi wumuvuduko ugomba gukorerwa ibizamini byimbaraga no kwipimisha.Ibyuma byuma byuma bigomba kandi gukora isesengura ryikigereranyo ku gishishwa kimwekimwe hanyuma ugasuzuma ibikoresho.

1. Kwemeza ikizamini cyimbaraga

Ikigeragezo cyimbaraga za valve nugupima valve mumugaragaro kugirango ugenzure imyanda hejuru yinyuma ya valve.Kuri valve hamwe na PN ≤ 32MPa, umuvuduko wikizamini wikubye inshuro 1.5 umuvuduko wizina, igihe cyikizamini ntikiri munsi yiminota 5, kandi ntagishobora kumeneka mugikonoshwa no gupakira gland kugirango kibe cyujuje ibisabwa.

2. Ikizamini cyo gukomera

Ikizamini gikozwe hamwe na valve ifunze burundu kugirango harebwe niba hari imyanda yamenetse hejuru yikimenyetso.Umuvuduko wikizamini, usibye kubinyugunyugu, kugenzura ibibiriti, indiba zo hepfo hamwe na trottle, bigomba gukorwa mubitutu byizina.Iyo bishobora kugenwa Ku gitutu cyakazi, ikizamini nacyo gishobora gukorwa inshuro 1.25 zumuvuduko wakazi, kandi hejuru yikimenyetso cya disiki ya valve igomba kuba yujuje ibisabwa niba idatemba.

Amategeko rusange yo gushiraho valve

1. Umwanya wo kwishyiriraho wa valve ntugomba kubangamira imikorere, gusenya no gufata neza ibikoresho, imiyoboro hamwe numubiri wa valve ubwayo, kandi isura nziza yubwiteraniro igomba kwitabwaho.

2. Kuri valve kumiyoboro itambitse, uruti rwa valve rugomba gushyirwaho hejuru cyangwa gushyirwaho kuruhande.Ntugashyire valve hamwe ninziga y'intoki hepfo.Imyonga, ibiti bya valve hamwe nintoki zintoki kumuyoboro muremure urashobora gushyirwaho mu buryo butambitse, kandi urunigi ruhagaritse kurwego rwo hasi rushobora gukoreshwa mugucunga kure gufungura no gufunga valve.

3. Gahunda irasa, nziza kandi nziza;kubirindiro kuri standpipe, niba inzira ibyemereye, intoki ya valve irakwiriye cyane gukoreshwa muburebure bwigituza, muri rusange 1.0-1.2m uvuye hasi, kandi uruti rwa valve rugomba gukurikiza iyerekwa rya Orientation.

4. Kubirindiro kumpande zihagaritse imiyoboro ihagaze, nibyiza kugira uburebure bumwe bwo hagati, kandi intera igaragara hagati yintoki ntizigomba kuba munsi ya 100mm;kuri valve kumpande-kuruhande itambitse ya horizontal, igomba guhindagurika kugirango igabanye intera iri hagati yimiyoboro.

5. Iyo ushyizeho indangagaciro ziremereye kuri pompe zamazi, guhanahana ubushyuhe nibindi bikoresho, hagomba gushyirwaho imirongo ya valve;iyo valve ikunze gukoreshwa kandi igashyirwaho hejuru ya 1.8m uvuye hejuru yimikorere, hagomba gushyirwaho urubuga rukora.

6. Niba hari akamenyetso kerekana umwambi kumubiri wa valve, icyerekezo cyumwambi nicyerekezo gitemba hagati.Mugihe ushyiraho valve, menya neza ko imyambi yerekeza mucyerekezo kimwe nogutemba kwicyerekezo muri pipe.

7. Mugihe ushyiraho flange ya flange, menya neza ko isura yanyuma ya flanges ebyiri iringaniye kandi yibanda hamwe, kandi gasketi ebyiri ntizemewe.

8. Mugihe ushyiraho valve ifite urudodo, kugirango byorohere gusenywa, valve ifite umugozi igomba kuba ifite ubumwe.Igenamigambi ryubumwe rigomba gutekereza kuborohereza kubungabunga.Mubisanzwe, amazi atembera muri valve mbere hanyuma akanyura mubumwe.

Valve yo kwirinda

1. Ibikoresho byumubiri wa valve ahanini bikozwe mucyuma, cyoroshye kandi ntigomba gukubitwa nibintu biremereye.

2. Mugihe utwara valve, ntujugunye kubushake;mugihe cyo guterura cyangwa kuzamura valve, umugozi ugomba guhambirwa kumubiri wa valve, kandi birabujijwe rwose kubihambira kumaboko y'intoki, uruti rwa valve n'umwobo wa flange.

3. Umuyoboro ugomba gushyirwaho ahantu heza ho gukorera, kubungabunga no kugenzura, kandi birabujijwe rwose gushyingura mu nsi.Imyanda iri mu miyoboro ishyinguwe mu buryo butaziguye cyangwa mu mwobo igomba kuba ifite amariba yo kugenzura kugira ngo byorohereze gufungura, gufunga no guhindura imyanda.

4. Menya neza ko insinga zidahwitse kandi zizingiye hamwe na hembe, amavuta yo kuyobora cyangwa kaseti ya PTFE
