- ARAN kupanga Trunnion Ball Valves ikupezeka mumitundu yambiri, zida, makulidwe ndi makalasi okakamiza ndipo amagwirizana kwathunthu ndi miyezo yapadziko lonse lapansi yopanga ANSI, ASME B16.34, API 6D, ISO17292, GOST, DIN/EN specifications etc.
- Valavu ya mpira wa Trunnion ili ndi kukula kwakukulu kopanga Kalasi 150 ~ Kalasi 2500, PN16 ~ PN420, zida zosiyanasiyana zimagwiritsidwa ntchito kunyamula mafakitale amadzi / nthunzi / mafuta ndi gasi, zimatha kukhala kutentha kochepa komanso kupanikizika kwambiri, zinthu zoyenera monga nitric acid, acetic acid, oxidizing media, urea, etc.
- The trunnion mavavu mpira chimagwiritsidwa ntchito mafuta kuyenga, mapaipi mtunda wautali, makampani mankhwala, kupanga mapepala, mankhwala, conservancy madzi, mphamvu yamagetsi, ulamuliro tauni, zitsulo ndi madera ena etc.
Kodi valavu ya mpira wa Trunnion ndi chiyani?
- Vavu ya mpira wa trunnion ndi valavu yotembenuza kotala ndipo mapangidwe a trunnion amatanthauza kuti gulu la mpira limathandizidwa ndi trunnion yochepetsera komanso tsinde kumtunda kwa chipinda cha valve.Mapangidwe awa amatchedwa trunnion mounted ball valve kapena trunnion ball valve.
- Valavu ya mpira wa trunnion nthawi zambiri imagwiritsa ntchito kukula kwakukulu ndi ntchito zothamanga kwambiri za valve, komanso kuchepetsa torque ya valve kuti igwire ntchito mosavuta.
- Tsinde lokhala ndi trunnion limatenga kuthamanga kuchokera pamzere, kulepheretsa kukangana kwakukulu pakati pa mpira ndi mipando, chifukwa chake mawotchi ogwiritsira ntchito ma valve amakhalabe otsika pakukakamiza kokwanira kogwira ntchito.
- Kodi mpando wa trunnion mpira umasindikiza bwanji?
- Kusindikiza kumatheka ndi mipando yamtundu wa pistoni yodzaza masika yomwe imatseka kutuluka pamene kuthamanga kwa mzere kumagwira pampando wakumtunda.Kupumula kwapang'onopang'ono kwapang'onopang'ono kumatsimikiziridwa chifukwa cha mapangidwe a trunnion ngati mipando yodzipumutsira yokha.Mpira umayendetsedwa ndi spindle yosindikizidwa yomwe woyendetsa amamangiriridwa.Mavavu ampira amapangidwa kuti azigwiritsidwa ntchito ngati zida zoyatsira/kuzimitsa kutuluka ndipo sayenera kugwiritsidwa ntchito kutulutsa madzi.Ma valve ayenera kukhala otseguka kapena otsekedwa nthawi zonse.
- Mapangidwe a mipando ya valve ya Trunnion ali ndi mawonekedwe ofunikira pazofunikira zosiyanasiyana:
- ● SELF RELIEVING SEATS / SINGLE RELIEF SEATS(SPE) and DOUBLE PISTON EFFECT SEATS (DEP)
- ● Mapangidwe a mipando ya DBB ndi DIB
- Mpira wa valve wa trunnion umakhazikika koma mipando imasinthasintha.Mpandowo uli ndi SELF RELIEVING SEATS/ SINGLE RELIEF SEATS (SPE) and DOUBLE PISTON EFFECT SEATS (DEP) design.Mapangidwe a SPE ndi njira imodzi yosindikizira uni-directional ndipo DEP ndi kusindikiza kwa bi-direction, ndi API 6D/ISO 14313 kutanthauzira.
- ARAN amagwiritsa ntchito valavu ya trunnion yopangira mipando imodzi yothandizira SPE-SPE ndi chipika chapawiri ndikutulutsa magazi DBB monga momwe amapangira.Koma mitundu ina mipando kamangidwe likupezeka pa pempho enieni.
- Single Piston Effect Seat Design mawonekedwe
- Mipando ya ma valves a mpira imapanikizidwa pa mpira pogwiritsa ntchito kasupe.
- Pamene kupsyinjika kwa thupi kumawonjezeka kuposa katundu wa kasupe, mipando imakankhidwa mmbuyo ndipo kupanikizika kumatulutsidwa pamzere.Izi zimatchedwa kuti single-piston effect (kupanikizika m'matumbo a thupi ndilo gawo lokhalo lochitapo kanthu) .Kupumula kwa cavity kumunsi kwa mtsinje, ngati mipando yonse ya valve ya mpira ndi ya single-piston effect design.Mpando uliwonse umadzichepetsera pawokha pabowo la thupi chifukwa cha kukanikiza pamzere.
- Chithunzi: Single Piston effect Seat Design
- Mapangidwe a Double Piston Effect Seat Design
- Pampando uwu, kupanikizika kwapakatikati, komanso kuthamanga kwapang'onopang'ono kwa thupi, kumapangitsa kukankhira komwe kumakankhira mphete pampira.Izi zimatchedwa double piston effect (kupanikizika mu chitoliro & kuti m'matumbo a thupi onse ndi magawo ochita zinthu). Mavavu a Mpira ndi mapangidwewa amafuna chipangizo chothandizira kuchepetsa kuthamanga kwa thupi kuti achepetse kuthamanga kwa thupi.
- Chithunzi: Mapangidwe Awiri a Piston Effect Seat
- Trunnion Ball valve DBB ndi DIB mipando matanthauzo a mapangidwe
- ● valavu ya mpira wa DBB (zotchinga ziwiri ndi valavu yotulutsa magazi)
- Mavavu a mpira a DBB akhale valavu imodzi yokhala ndi mipando iwiri yopanda unidirectional.Chotsekereza ichi ndi valavu yotulutsa magazi imasindikiza kupsinjika kwa mbali zonse za valve.Valavu iyi siyimapereka kudzipatula kwapawiri pomwe mbali imodzi yokha ili pamavuto.
- Valavu ya mpira wa DBB imatha kuonedwa ngati valavu yokhala ndi mipando iwiri ya piston (SPE).
- ● valavu ya mpira wa DIB (kudzipatula kawiri ndi valavu yotulutsa magazi)
- Valavu ya DIB ndi valavu imodzi yokhala ndi mipando iwiri yolumikizirana.Valavu yodzipatula iyi iwiri-ndi-yotulutsa magazi imapereka chisindikizo chowonjezereka motsutsana ndi kupanikizika kuchokera kumbali imodzi yokha.Chinthu cha DIB ichi chikhoza kuperekedwa kumbali imodzi kapena mbali zonse ziwiri.Valavu imapereka kudzipatula kawiri kuchokera ku kukanikiza kumalekezero onse a valavu koma sikungathetse kupanikizika kwa thupi kudutsa mipando.
- Mbali ya DIB imatha kuperekedwa mbali imodzi kapena mbali zonse ziwiri.
- Vavu yokhala ndi mipando iwiri ya piston effect (DPE) imakhala yodzipatula kawiri komanso yotulutsa magazi (DIB-1).Vavu yokhala ndi mpando umodzi wa SPE ndi mpando wina wa DPE ndi DIB-2 valavu yopangira.Valavu ya DIB-2 idzakhala ndi njira yokhazikitsira yomwe mumakonda.
