Aya mabwiriza akurikizwa mugushiraho amarembo, guhagarika imipira, imipira yumupira, ikinyugunyugu hamwe nigitutu kigabanya imyanda munganda za peteroli. Kwishyiriraho ibiciro bya cheque, indangagaciro z'umutekano, kugenzura imiyoboro n'imitego ya parike bigomba gukurikiza amabwiriza abigenga. Aya mabwiriza ntabwo akurikizwa mugushiraho indiba kumasoko y'amazi yo munsi y'ubutaka hamwe n'imiyoboro y'amazi.

1 Amahame yimiterere ya valve

1.1 Indangagaciro zigomba gushyirwaho ukurikije ubwoko nubunini byerekanwe kumuyoboro nigishushanyo mbonera cyibikoresho (PID). Iyo PID ifite ibisabwa byihariye byo kwishyiriraho ibibanza bimwe na bimwe, bigomba gushyirwaho ukurikije ibisabwa.

1.2 Indangagaciro zigomba gutondekwa ahantu byoroshye kuboneka, gukora no kubungabunga. Imyanya ku murongo w'imiyoboro igomba gutondekwa muburyo bukomatanyije, kandi hagomba gusuzumwa urubuga rukora cyangwa urwego.

2 Ibisabwa kugirango ushyireho valve

2.1 Iyo koridor ya pipe yinjira no gusohoka igikoresho ihujwe numuyoboro wingenzi kuri koridoro yimiyoboro yikimera cyose,kuzimyaigomba gushyirwaho. Ahantu ho kwinjirira mumibande hagomba kuba hagati kuruhande rwibikoresho, kandi hagomba gushyirwaho urubuga rukenewe rwo gukora cyangwa urubuga rwo kubungabunga.

2.2 Indangagaciro zigomba gukoreshwa kenshi, kubungabunga no gusimburwa zigomba kuba ahantu hashobora kuboneka byoroshye kubutaka, urubuga cyangwa urwego.Umuyoboro wa pneumatike n'amashanyarazibigomba kandi gushyirwa ahantu byoroshye kuboneka.

2.3 Indangagaciro zidakeneye gukoreshwa kenshi (gusa zikoreshwa mugihe utangiye no guhagarara) nazo zigomba gushyirwa ahantu hashobora gushyirwaho urwego rwigihe gito niba rudashobora gukorerwa hasi.

2.4 Uburebure bwa centre ya valve handwheel kuva hejuru yimikorere iri hagati ya 750 na 1500mm, kandi uburebure bukwiye ni

1200mm. Uburebure bwububiko bwa valve budakeneye gukoreshwa kenshi burashobora kugera kuri 1500-1800mm. Iyo uburebure bwo kwishyiriraho budashobora kugabanuka kandi ibikorwa birakenewe kenshi, urubuga rukora cyangwa intambwe bigomba gushyirwaho mugihe cyo gushushanya. Imyanda iri mu miyoboro n'ibikoresho by'itangazamakuru rishobora guteza akaga ntibishobora gushyirwa mu burebure bw'umutwe w'umuntu.

2.5 Iyo uburebure bwikigo hagati ya valve handwheel kuva hejuru yimikorere irenga 1800mm, hagomba gushyirwaho ibikorwa bya spock. Intera y'urunigi rw'amasoko kuva hasi igomba kuba hafi 800mm. Igikoresho cya spocket kigomba gushyirwaho kugirango umanike impera yumurongo wurukuta kurukuta cyangwa inkingi hafi kugirango wirinde kugira ingaruka.

2.6 Kubirindiro byashyizwe mumwobo, mugihe igifuniko gishobora gufungurwa kugirango gikore, intoki yintoki ntigomba kuba munsi ya 300mm munsi yumwobo. Iyo iri munsi ya 300mm, inkoni yo kwagura valve igomba gushyirwaho kugirango ikore intoki zayo muri 100mm munsi yumupfundikizo.

2.7 Kubirindiro byashyizwe mumwobo, mugihe bikenewe gukorerwa hasi, cyangwa indangagaciro zashyizwe munsi yo hejuru (platform),inkoni yo kwagura valve irashobora gushirwahokuyagura kugeza kumurongo, hasi, urubuga rwo gukora. Intoki y'intoki yo kwagura igomba kuba 1200mm uvuye hejuru yimikorere. Imyanya ifite diameter nominal iri munsi cyangwa ihwanye na DN40 hamwe nu murongo uhujwe ntugomba gukoreshwa ukoresheje amasoko cyangwa inkoni yo kwagura kugirango wirinde kwangirika. Mubisanzwe, ikoreshwa rya spockets cyangwa inkoni yo kwagura kugirango ikore valve igomba kugabanywa.

2.8 Intera iri hagati yintoki za valve itondekanye kuri platifomu nu nkombe ya platifomu ntigomba kurenza 450mm. Iyo igiti cya valve na handwheel bigeze mugice cyo hejuru cya platifomu kandi uburebure buri munsi ya 2000mm, ntibigomba kugira ingaruka kumikorere no kunyura mubakoresha kugirango birinde gukomeretsa umuntu.

3 Ibisabwa kugirango ushyireho valve nini

3.1 Imikorere ya valve nini igomba gukoresha uburyo bwo kohereza ibikoresho, kandi umwanya ukenewe muburyo bwo kohereza ugomba gutekerezwa mugihe washyizeho. Mubisanzwe, indangagaciro zifite ubunini burenze amanota akurikira zigomba gutekereza gukoresha valve ifite uburyo bwo kohereza ibikoresho.

3.2 Imyanda nini igomba kuba ifite imitwe kuruhande rumwe cyangwa impande zombi. Inyuguti ntizigomba gushyirwaho kumuyoboro mugufi ugomba gukurwaho mugihe cyo kubungabunga, kandi inkunga yumuyoboro ntigomba kugira ingaruka mugihe ikuweho. Intera iri hagati yinyuguti na flange flange igomba kuba irenze 300mm.

4 Ibisabwa kugirango ushireho valve kumuyoboro utambitse

4.1 Keretse niba bisabwa ukundi nuburyo, intoki za valve zashyizwe kumuyoboro utambitse ntizishobora kureba hasi, cyane cyane intoki za valve kumuyoboro wibitangazamakuru biteye akaga birabujijwe rwose kureba hasi. Icyerekezo cya valve handwheel igenwa muburyo bukurikira: uhagaritse hejuru; mu buryo butambitse; uhagaritse hejuru hamwe na 45 ° ibumoso cyangwa iburyo; uhagaritse hepfo hamwe na 45 ° ibumoso cyangwa iburyo; ntabwo ihagaritse.

5 Ibindi bisabwa kugirango ushireho valve

5.1 Imirongo yo hagati ya valve kumiyoboro ibangikanye igomba guhuzwa bishoboka. Iyo indangagaciro zitunganijwe neza, intera ya net hagati yintoki ntizigomba kuba munsi ya 100mm; imibande nayo irashobora guhindagurika kugirango igabanye intera iri hagati yimiyoboro.

5 . Iyo valve ifite flange yuzuye, ibikoresho byumwuga bigomba gusabwa gushiraho flange ya convex kumunwa uhuye.

5.3 Keretse niba hari ibisabwa byihariye kubikorwa, indiba ziri kumuyoboro wo hasi wibikoresho nkiminara, reaction, hamwe nibikoresho bihagaritse ntibishobora gutondekwa mumajipo.

5.4. .

5.5 Umuyoboro wishami ufunga valve kumurongo wububiko ntukorwa kenshi (gusa iyo uhagaze kugirango ubungabunge). Niba nta ngazi ihoraho, umwanya wo gukoresha urwego rwigihe gito ugomba gutekereza.

5.6 Iyo hafunguwe umuvuduko mwinshi cyane, imbaraga zo gutangira nini. Agace kagomba gushyirwaho kugirango gashyigikire valve no kugabanya imihangayiko yo gutangira. Uburebure bwo kwishyiriraho bugomba kuba 500-1200mm.

5.7 Ibyuma byamazi yumuriro, ibyuka byumuriro, nibindi mubice byumupaka wibikoresho bigomba gutatanwa kandi ahantu hizewe byoroshye kubakoresha kubigeraho mugihe habaye impanuka.

5.8 Itsinda rya valve ryumuriro wo kuzimya umuriro wo gukwirakwiza amashyiga yo gushyushya bigomba kuba byoroshye gukora, kandi umuyoboro wo kugabura ntugomba kuba munsi ya 7.5m uvuye mumatanura.

5.9 Mugihe ushyizeho indangagaciro zometse kumuyoboro, bigomba guhinduka hafi ya valve kugirango bisenywe byoroshye.

5.10 Imyanda ya Wafer cyangwa ikinyugunyugu ntigishobora guhuzwa neza na flanges yizindi valve hamwe nibikoresho bya pipe. Umuyoboro mugufi ufite flanges kumpande zombi ugomba kongerwaho hagati.

5.11 Umuyoboro ntugomba gukorerwa imitwaro yo hanze kugirango wirinde guhangayika cyane no kwangirika
