Kodi ma valve okwera mpira a ATEX Trunnion ndi chiyani?

  Zotsatira ATEX trunnion wokwera valavu ya mpirakumatanthauza kuti mpirawo umakakamizidwa ndi ma bere ndipo amangololedwa kusinthasintha, kuchuluka kwa hydraulic katundu kumathandizidwa ndi Zoletsa za System, zomwe zimapangitsa kuti pakhale kutsika kwapakati komanso kutopa kwa shaft.

Kuthamanga kwa mapaipi kumayendetsa mpando wakumtunda motsutsana ndi mpira woyima kotero kuti kuthamanga kwa mzere kumakakamiza mpando wakumtunda kupita ku mpirawo kuti utseke.Kuyika kwa mpira kumakoka kumatengera kuthamanga kwa mzere, kulepheretsa kukangana kwakukulu pakati pa mpira ndi mipando, kotero kuti ngakhale torque yogwira ntchito ikadali yotsika.Izi ndizopindulitsa makamaka pamene valavu ya mpira imayendetsedwa chifukwa imachepetsa kukula kwa actuator ndipo motero ndalama zonse za phukusi la valve actuation.The trunnion imapezeka misinkhu yonse ndi makalasi onse opanikizika koma makamaka ndi zazikulu zazikulu komanso zovuta kwambiri.

Zazikulu za NORTECH ATEX Trunnion zokwera ma valve a mpira

1.Double Block and Bleed(DBB)

Vavu ikatsekedwa ndipo nthiti yapakati imatsanulidwa kudzera mu valavu yotulutsa, mipando yakumtunda ndi yakumunsi imatsekeka.Ntchito ina ya chipangizo chotulutsa ndi chakuti mpando wa valve ukhoza kufufuzidwa ngati pali kutuluka panthawi yoyesedwa.Kuonjezera apo, madipoziti mkati mwa thupi akhoza kutsukidwa kupyolera mu chipangizo chotulutsira.chipangizo chotulutsira chapangidwa kuti chichepetse kuwonongeka kwa mpando ndi zonyansa pakati.

2.Low Operating Torque

Valavu ya mpira wa trunnion imatenga mawonekedwe a mpira wa trunnion ndi mpando wa valve woyandama, kuti ikwaniritse torque yotsika pansi pa kukakamizidwa.Imagwiritsa ntchito PTFE yodzipangira yokha ndi zitsulo zotsetsereka kuti muchepetse kugundana mpaka kutsika kwambiri molumikizana ndi kulimba kwambiri komanso tsinde lapamwamba.

3.Emergency Kusindikiza Chipangizo

Mavavu a mpira okhala ndi m'mimba mwake kuposa kapena wofanana ndi 6'(DN150) onse amapangidwa ndi chipangizo chojambulira chosindikizira pa tsinde ndi mpando.Pamene mphete yapampando kapena tsinde O mphete yawonongeka chifukwa cha ngozi, chosindikizira chofananiracho chikhoza kubayidwa ndi chipangizo cha jakisoni wa sealant kupewa kutayikira kwapakatikati pa mphete yapampando ndi tsinde.Ngati ndi kotheka, makina othandizira osindikizira angagwiritsidwe ntchito kutsuka ndi kudzoza mpando kuti ukhale waukhondo.

4.Moto Wopanga Mapangidwe Apangidwe

Pakayaka moto pakugwiritsa ntchito valavu, mphete yapampando, tsinde O mphete ndi mphete yapakatikati ya O yopangidwa ndi PTFE, mphira wazinthu zina zopanda zitsulo amawonongeka kapena kuonongeka pansi pa kutentha kwakukulu. valavu idzakankhira chosungira mpando mofulumira ku mpira kuti ipangitse mphete yosindikizira yachitsulo kuti igwirizane ndi mpirawo ndikupanga chitsulo chothandizira kuzitsulo zosindikizira zachitsulo, zomwe zingathe kulamulira bwino kutayikira kwa valve. 607, API 6FA, BS 6755 ndi mfundo zina.

6.Reliable mpando kusindikiza dongosolo

Kusindikiza pampando kumazindikirika kudzera m'mipando iwiri yoyandama, imatha kuyandama kuti itseke madzi, kuphatikiza kusindikiza mpira ndi kusindikiza thupi. idapangidwa bwino, yomwe imazindikira kusindikiza kuthamanga kwambiri ndi kuthamanga kwa sing'anga yokha. Mitundu iwiri yotsatira ya kusindikiza mpira imatha kukwaniritsidwa.

7.Kusindikiza Kumodzi

(Automatic Pressure Relief in Middle Cavity of Valve) Nthawi zambiri, kusindikiza kumodzi kumagwiritsidwa ntchito.Pamene mipando yodziyimira payokha yodzaza kumtunda ndi pansi pamitsinje yosindikizira ikugwiritsidwa ntchito, kupanikizika kwambiri mkati mwa valavu kumatha kuthana ndi kulimba kwa kasupe, kuti mpando utuluke mu mpira ndikuzindikira mpumulo wokhazikika wopita kumunsi kwa mtsinje. .Kumtunda kwa mtsinje: Pamene mpando ukuyenda axially motsatira valavu, kukanikiza "P" kochokera kumtunda (kulowetsa) kumapanga mphamvu yobwereranso pa A1, Monga A2 ndi yapamwamba kuposa A1, A2-A1 = B1, mphamvu pa B1 idzakankhira mpando ku mpira ndikuzindikira kusindikizidwa kolimba kwa gawo lakumtunda

Mtsinje wapansi: Kuthamanga kwa "Pb" mkati mwa valavu Cavity kumawonjezeka, mphamvu yogwiritsidwa ntchito pa A3 imakhala yochuluka kuposa ya A4.Monga A3-A4 = B2, kusiyana kwa kuthamanga kwa B2 kudzagonjetsa mphamvu ya masika kuti mpando utulutsidwe kuchokera ku mpira ndi kuzindikira mpumulo wa valve kumunsi kwa mtsinje pambuyo pake, mpando ndi mpira zidzasindikizidwanso pansi pa kasupe. .

Kusindikiza kwachiwiri: Kutsika.

Kusiyanitsa kwa kuthamanga kukatsika kapena kulibe kusiyanitsa kokakamiza, mpando woyandama umasuntha mozungulira pa valve pansi pa zochitika za masika ndikukankhira mpando ku mpira kuti utseke mwamphamvu.Pamene mphamvu ya valve P ikuwonjezeka, mphamvu yomwe imagwira pa A4 ya mpando wa valve pamwamba kwambiri kuposa mphamvu ya A3, A4- A3 = B1. kusindikiza kolimba kwa gawo lakumtunda.

9.Chida Chothandizira Chitetezo

Monga valavu ya mpira imapangidwira ndi kusindikiza kwapamwamba komanso kwachiwiri komwe kumakhala ndi pistoni iwiri, ndipo phokoso lapakati silingathe kuzindikira mpumulo wokhazikika, valavu yotetezera chitetezo iyenera kuikidwa pa thupi kuti iteteze kuopsa kwa kuwonongeka kwakukulu. M'kati mwa valavu yomwe imatha kuchitika chifukwa cha kuwonjezereka kwa kutentha kwapakati.Kulumikizana kwa valve yotetezera chitetezo nthawi zambiri kumakhala NPT 1/2.Mfundo ina yomwe iyenera kuzindikiridwa ndi yakuti sing'anga ya valve yothandizira chitetezo imatulutsidwa mwachindunji mumlengalenga.Ngati kutulutsa kwachindunji mumlengalenga sikuloledwa, timalimbikitsa kuti valavu ya mpira yokhala ndi mawonekedwe apadera odziwikiratu kumtunda kwa mtsinje iyenera kugwiritsidwa ntchito. Onani zotsatirazi kuti mudziwe zambiri.Chonde zisonyezeni mu dongosolo ngati simukusowa valavu yothandizira chitetezo kapena ngati mukufuna kugwiritsa ntchito valavu ya mpira yokhala ndi dongosolo lapadera lochepetsera kuthamanga kwamtunda kumtunda.

10.Mapangidwe Apadera a Zothandizira Zodziwikiratu Zotsitsimula Kumtunda Wapamwamba

Monga valavu ya mpira idapangidwa ndi zosindikizira zapamwamba komanso zachiwiri zomwe zimakhala ndi pistoni iwiri, ndipo pakatikati pakatikati sungazindikire mpumulo wokhawokha, valavu ya mpira ith dongosolo lapadera likulimbikitsidwa kuti likwaniritse zofunikira zowonongeka ndikuonetsetsa kuti palibe kuipitsa. M'mapangidwe ake, mtsinje wamtunda umatenga chisindikizo choyambirira ndipo mtsinje wapansi umagwiritsa ntchito kusindikiza koyamba ndi kwachiwiri Pamene valavu ya mpira yatsekedwa, kuthamanga kwa valve kungathe kuzindikira mpumulo wopita kumtunda, kuti apewe. Mpando woyamba ukawonongeka ndikutuluka, mpando wachiwiri ungathenso kusindikiza. mayendedwe akunsi kwa mtsinje. Onani zojambula zotsatirazi kuti musindikize mfundo ya valve ndi dongosolo lapadera

13. Tsinde Lowonjezera

Ponena za valavu yophatikizika, tsinde yowonjezera ikhoza kuperekedwa ngati ntchito yapansi ikufunika. Tsinde lotambasula limapangidwa ndi tsinde, valavu ya jekeseni yosindikizira, ndi valavu yotulutsa madzi yomwe ingathe kufalikira pamwamba kuti ikhale yosavuta.Ogwiritsa ntchito akuyenera kuwonetsa zofunikira ndi kutalika kwa tsinde poika maoda.Kwa valavu ya mpira yoyendetsedwa ndi magetsi, pneumatic ndi pneumatic - hydraulic actuators, kutalika kwa tsinde kuyenera kuchokera pakati pa payipi kupita pamwamba.
