Valavu Yapamwamba Kwambiri Yapaipi ...
Kodi valavu ya Pneumatic Globe ndi chiyani?
Valavu Yophimba Bellows Seal Globe, Valavu ya Pneumatic GlobeNthawi zambiri imapangidwa ndikupangidwa motsatira muyezo wa Germany ndi muyezo wa ku Europe EN13709. Monga mwachizolowezi, valavu yake yotseka yoyenda molunjika imagwiritsidwa ntchito kuyambitsa, kuyimitsa kapena kuwongolera kuyenda kwa madzi pogwiritsa ntchito chotchinga chotchedwa disc.Ma valve a Bellows Seal Globe, Pneumatic Globe valveNdi abwino kwambiri ndipo amagwiritsidwa ntchito kwambiri poletsa kapena kuletsa kuyenda kwa madzi kapena mpweya kudzera mu chitoliro kuti achepetse ndikuwongolera kuyenda kwa madzi ndipo nthawi zambiri amagwiritsidwa ntchito m'mapaipi ang'onoang'ono.
idapangidwa kuti ikwaniritse zofunikira zokhwima komanso zovuta zogwirira ntchito. Kupatula msonkhano wamba wolongedza monga valavu yonse ya chipata,valavu yotsekera chisindikizo cha bellowsIlinso ndi chipangizo chopakira zinthu cha bellow. Ma bellow ooneka ngati accordion amakhala mkati mwa chubu chokhuthala chachitsulo. Malekezero amodzi a ma bellow amalumikizidwa ku tsinde la valavu, ndipo malekezero ena amalumikizidwa ku chubu choteteza. Ndi flange yayikulu ya chubucho yolumikizidwa mwamphamvu mu bonnet ya valavu, pali chisindikizo chopanda kutayikira.
nthawi zambiri pamakhala mapangidwe atatu akuluakulu a thupi kapena mapangidwe aMa valve a Bellows Seal Globe:
- 1). Chitsanzo Chokhazikika (komanso monga Chitsanzo cha Tee kapena T - Chitsanzo kapena Z - Chitsanzo)
- 2). Chitsanzo cha ngodya
- 3). Kapangidwe ka Oblique (komwe kumadziwikanso kuti Kapangidwe ka Wye kapena Kapangidwe ka Y)
Mbali zazikulu za Bellows Seal Globe Valve Pneumatic Globe valve
Makamaka njira zamakemikolo, madzi omwe ali m'mapaipi nthawi zambiri amakhala oopsa, owopsa komanso oopsa. Ma valve a Pneumatic Globe amagwiritsidwa ntchito poletsa kutuluka kwa mankhwala aliwonse oopsa mumlengalenga. Zinthu za thupi zimatha kusankhidwa kuchokera kuzinthu zonse zomwe zilipo, ndipo pansi pake pakhoza kuperekedwa muzinthu zosiyanasiyana monga 316Ti, 321, C276 kapena Alloy 625.
- 1). Pali mitundu yosiyanasiyana ya luso monga momwe imapezeka mu mawonekedwe wamba (mawonekedwe olimba), mawonekedwe a ngodya, ndi mawonekedwe a Wye (mawonekedwe a Y).
- 2). Mivi yachitsulo imatseka tsinde loyenda ndipo imawonjezera kulimba kwa ma valve otsekera tsinde odzaza.
- 3).Zisindikizo ziwiri zachiwiri za tsinde: a) Mpando wakumbuyo uli pamalo otseguka; b) Kupaka Graphite.
- 5). Kukonza ndi kukonzanso mipando mosavuta, pazifukwa zosiyanasiyana.
- 6).. Mtunda waufupi woyenda wa diski (stroke) pakati pa malo otseguka ndi otsekedwa,Ma valve a globe otsekereza a Bellowsndi abwino ngati valavu iyenera kutsegulidwa ndi kutsekedwa pafupipafupi;
- 7). Amagwiritsidwa ntchito kwambiri m'maiko onse a European Union, komanso m'maiko ena.
