I-DIN EN 13709 ANGLE TYPE GLOBE VALVE MANUFACTURER

1.1 Umklamo Womzimba Wohlobo Lwe-engela

Isici esivelele kakhulu sale valve umzimba wayo onamaphethini e-engeli, lapho ama-port okungena kanye ne-outlet eqondiswa khona kuma-degree angu-90. Lo mklamo:

Ishintsha indlela yokugeleza.

Kunciphisa isidingo sezindololwane zamapayipi ezihlukene.

Inciphisa ukwehla kwengcindezi uma kuqhathaniswa nevalvu yembulunga eqondile ehlanganiswe nendololwane.

Kuthuthukisa ukusebenza kahle kokugeleza kwezinye izinto ezifakiwe.

Indlela yokugeleza kwangaphakathi ivumela uketshezi ukuthi lungene ku-valve, ludlule esihlalweni, futhi luphume nge-engeli efanele.

1.2 Ukuxhumeka Kwesiphetho Se-Flange (I-DIN Standard)

Ivalvu ifakwe iziphetho ezigobile ezenziwe ngokwezindinganiso ze-DIN ezifana nalezi:

I-DIN EN 1092-1

I-DIN PN10 / PN16 / PN25 / PN40 (izilinganiso zokucindezela)

Ukuxhumeka okuhlanganisiwe kunikeza:

Ukufakwa nokususwa okulula.

Ukuvalwa okuthembekile ngama-gasket.

Ukufaneleka kwezicelo ezisebenzisa umfutho ophezulu kanye nezisebenzisa izinga lokushisa eliphezulu.

Lawa ma-flange aqinisekisa ukuhambisana nezinhlelo zamapayipi aseYurophu.

1.3 Izingxenye Eziyinhloko

I-valve ejwayelekile ye-DIN flange end angle globe engenazo izimbobo iqukethe:

Umzimba – Insimbi ebunjiwe noma ehlanganisiwe, insimbi engagqwali, noma insimbi ehlanganisiwe.

Ibhonethi – Umklamo oboshwe ngebholidi noma ovalwe ngokucindezela.

Idiski (Ipulaki) – Izilawuli zigeleza ngezihlalo ezibhekene nesihlalo sevalvu.

Indandatho Yesihlalo - Ihlinzeka ngomphezulu wokuvala.

Isiqu – Sidlulisela ukunyakaza kusuka ku-actuator/handwheel kuya kudiski.

Ukupakisha - Kuvala nxazonke kwesiqu ukuze kuvinjelwe ukuvuza.

I-Gland kanye ne-Gland Flange – Izinto zokupakisha ezicindezelwe.

Isondo lesandla noma i-Actuator – Ukusebenza ngesandla noma okuzenzakalelayo.

Izinto ezivamile zifaka:

Izinto Zomzimba

Insimbi Yekhabhoni Ebunjiwe (isb., GS-C25)

Ithusi (lokusetshenziswa kwamanzi)

Izinto Zokupakisha

Njengoba lokhu kuyivalvu yohlobo olungenazo izimbobo, ukuvalwa kwesiqu kuncike ezintweni zokupakisha ezifana nalezi:

I-Graphite

I-PTFE

I-Aramid fiber

Ukungabikho kwe-bellows kwenza i-valve ibe eyongayo kodwa kudinga ukulungiswa kokupakisha njalo.

Ama-valve e-DIN globe akhiqizwa ngokwezigaba zokucindezela zaseYurophu:

I-PN10

I-PN16

I-PN25

I-PN40

Amazinga okushisa ajwayelekile:

Kufika ku-400°C (insimbi yekhabhoni)

Kufika ku-550°C (insimbi ye-alloy)

Imikhawulo ephansi incike ekukhetheni izinto ezibonakalayo

Lawa ma-valve afaneleka ku:

Intuthu

Amafutha ashisayo

Amanzi

Umoya ocindezelwe

Amakhemikhali angaboliyo

5.1 Ukulawula Ukugeleza Okunembile

Ama-valve e-Globe anikeza izici ezinhle kakhulu zokugoqa ngenxa yokunyakaza kwe-linear disc.

5.2 Ukufakwa Okuncane

Iphethini ye-engeli isusa isidingo sokufakwa kwe-elbow okuhlukile.

5.3 Izindleko Ezingabizi

Ngaphandle kokuvalwa kwe-bellows, i-valve yile:

Kubiza kancane

Kulula ekwakheni

Kulula ukuyinakekela

5.4 Umklamo Oqinile

Ifanele izindawo zezimboni ezidinga kakhulu.

6.1 Ingozi Yokuvuza Kwesiqu

Ngaphandle kwe-bellows, i-valve incike ekupakishweni. Ngokuhamba kwesikhathi:

Ukupakisha kungase kuphele.

Kungadingeka ukulungiswa noma ukushintshwa.

Ukukhishwa okuncane komoya okusabalala kungenzeka.

6.2 Ukwehla Okuphezulu Kwengcindezi

Uma kuqhathaniswa nama-valve esango, ama-valve embulunga adala ukulahlekelwa okukhulu kwengcindezi ngokwemvelo.

6.3 Akufanelekile Ukugeleza Okugcwele Kwebhore

Ukumelana nokugeleza kukhulu ngenxa yendlela yokugeleza kwangaphakathi.

Amavalvu embulunga yohlobo lwe-DIN flange end angle angenazo izimbozo avame ukusetshenziswa ku:

7.1 Izitshalo Zikagesi

Imigqa ye-steam

Izinhlelo zokuphakela amabhoyila

Izinhlelo zokubuyisa i-condensate

7.2 Imboni Yamakhemikhali

Izindleko Eziphansi Ziphezulu

Ukulungiswa Kudinga ukulungiswa kokupakisha Okuncane

Ukulawulwa Kokukhishwa Komoya Okumaphakathi Kuhle Kakhulu

Ingozi Yokuvuza Ingenzeka Iphansi Kakhulu

Ubunzima Obulula Obuyinkimbinkimbi Obuningi

Amavalvu avaliwe nge-bellows ayathandwa kakhulu ku:

Uketshezi olunobuthi

Amagesi ayingozi

Izicelo zokuhlanza umoya

Izinhlobo ezingezona izifutho ziyathandwa kakhulu kulezi:

Izinsizakalo zezimboni ezijwayelekile

Izinhlelo zomusi namanzi

Amaphrojekthi anakekela isabelomali

Faka ngokwendlela yokumaka ukugeleza.

Qinisekisa ukukhetha okulungile kwe-gasket ukuze uthole isilinganiso se-DIN flange.

Qinisa amabhawodi e-flange ngendlela ephambene.

Nikeza ukwesekwa okwanele ukuze ugweme ukucindezeleka kwepayipi.

Vumela indawo yokusebenza nokunakekelwa kwesiteringi sesandla.

Kuma-valve e-angle, qiniseka ukuthi indlela yokukhipha ihambisana kahle namapayipi angezansi komfula.

Njengoba leli valve lingasebenzisi uphawu lwe-bellows, ukulungiswa okuvamile kubalulekile:

Hlola ukupakisha ukuze kutholakale ukuthi akunawo yini amanzi.

Qinisa amabholti endlala ngokulinganayo uma kuvela ukuvuza.

Shintsha ukupakisha uma kugqokwe.

Hlola isihlalo nediski ukuthi azigugi yini.

Gcoba izintambo zesiqu ngezikhathi ezithile.

Ukugcinwa kokuvimbela kwandisa impilo yesevisi kanye nokuthembeka.

Lawa ma-valve avame ukukhiqizwa futhi ahlolwe ngokuya ngalezi zindlela ezilandelayo:

I-DIN EN 13709 (Amavalvu e-Globe)

EN 12266 (Ukuhlolwa kwengcindezi)

I-ISO 5208 (Ukuhlolwa kweValve)

I-DIN EN 1092-1 (Ubukhulu be-Flange)

Ukuhlolwa kokuvuza kwamanzi kanye nokuvuza kwesihlalo kwenziwa ngaphambi kokulethwa.
