API 6D API608 Cast Steel Trunnion Mounted Ball Valve China fakitale
Kodi Cast steel trunnion ball valve ndi chiyani?
A Dulani zitsulo za trunnion mpira valvekumatanthauza 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.
Ubwino wa mapangidwe a mpira wa trunnion ndi torque yotsika, kugwira ntchito mosavuta, kuvala kwa mipando (kupatula tsinde/mpira kumalepheretsa kukweza ndi kutha kwa mipando yakumunsi kumapangitsa magwiridwe antchito ndi moyo wautumiki), kusindikiza kwapamwamba pazovuta zonse komanso zotsika (zosiyana makina opangira masika ndi kuthamanga kwa mzere wokwera kumagwiritsidwa ntchito ngati chosindikizira motsutsana ndi mpira woyima pakutsika kotsika komanso kuthamanga kwambiri).
Zofunikira zazikulu za NORTECH Cast steel trunnion mpira valve
1. Double Block ndi 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.
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.
Sealant Injection Chipangizo
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. lakonzedwa bwino, amene amazindikira mkulu kuthamanga kusindikiza ndi kuthamanga kwa sing'anga palokha. The zotsatirazi mitundu iwiri ya mpira kusindikiza akhoza anazindikira.
7.Kusindikiza Kumodzi
(Automatic Pressure Relief in Middle Cavity of Valve) Nthawi zambiri, kusindikiza kumodzi kumagwiritsidwa ntchito.Pamene kasupe wodziyimira pawokha wodzaza kumtunda ndi pansi pamitsinje yosindikizira mipando imagwiritsidwa ntchito, kupanikizika kwambiri mkati mwa valavu kumatha kuthana ndi kulimba kwa kasupe, kuti mpando utuluke mu mpira ndikuzindikira mpumulo wokhazikika wopita kumunsi. .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. .
8.Kusindikiza kawiri (Pistoni iwiri)
Vavu ya mpira wa trunnion imatha kupangidwa ndi mawonekedwe osindikiza kawiri mpirawo usanachitike komanso pambuyo pazikhalidwe zina zapadera zautumiki komanso zofunikira za ogwiritsa ntchito.Lili ndi double piston effect.Munthawi yabwino, valavu nthawi zambiri imagwiritsa ntchito kusindikiza koyambirira. Mpando woyamba wotisindikiza ukawonongeka ndipo umayambitsa kutayikira, mpando wachiwiri ukhoza kugwira ntchito yosindikiza ndikuwonjezera kudalirika kosindikiza.mpando umatenga dongosolo lophatikizidwa.Chisindikizo choyambirira ndi chitsulo ku chisindikizo chachitsulo.Chisindikizo chachiwiri ndi mphira wa fluorine O mphete yomwe ingatsimikizire kuti valavu ya mpira imatha kufika pa kusindikiza kutsekemera.Kusiyana kwapanikizako kukakhala kotsika kwambiri, mpando wosindikizira umakankhira mpirawo panyengo ya masika kuti uzindikire kusindikiza koyamba.Kusiyana kwa kuthamanga kukakwera, mphamvu yosindikiza ya mpando ndi thupi imawonjezeka moyenerera kuti asindikize bwino mpando ndi mpira ndikuonetsetsa kuti ntchito yosindikiza ikugwira bwino.
Kusindikiza koyamba: Kumtunda.
Kusiyanitsa kwa kuthamanga kukatsika kapena kulibe kusiyanitsa, mpando woyandama umayenda mozungulira pa valve pansi pa zochitika za kasupe ndikuponyera mpando ku mpira kuti utseke mwamphamvu.Mpando wa vavu ukakhala wapamwamba kuposa mphamvu yomwe ikugwiritsidwa ntchito pagawo A1, A2- A1=B1. Chifukwa chake, mphamvu ya B1 idzakankhira mpando ku Mpira ndikuzindikira kusindikizidwa 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 kumtunda.
Kujambula kwa mfundo za valve valve kumtunda ndi kumtunda kusindikiza
Mfundo yojambulira pabowo la valve yotsitsa kuthamanga kwa mtsinje kumtunda ndi kusindikiza kwa mitsinje
12.Kukaniza kwa Corrosion ndi Kukaniza Stress Resistance
Ndalama zina za dzimbiri zatsala pa makulidwe a khoma la thupi.
Tsinde la chitsulo cha carbon, shaft yokhazikika, mpira, mpando ndi mphete zapampando zimayikidwa ndi nickel plating malinga ndi ASTM B733 ndi B656. Komanso, zipangizo zosiyanasiyana zolimbana ndi dzimbiri zilipo kwa ogwiritsa ntchito kuti asankhe. kusankhidwa molingana ndi NACE MR 0175 / ISO 15156 kapena NACE MR 0103, ndipo kuwongolera bwino kwambiri ndi kuyang'anira khalidwe kuyenera kuchitidwa panthawi yopanga kuti akwaniritse zofunikira pamiyezo ndikukwaniritsa mikhalidwe yautumiki mu chilengedwe cha sulfure.
11.Chitsimikizo cha Kuwomba
Tsinde limatenga mawonekedwe otsimikizira kuphulika. Tsinde limapangidwa ndi phazi pansi pake kotero kuti poyika chivundikiro chakumtunda ndi wononga, tsinde lisawululidwe ndi sing'anga ngakhale ngati kuthamanga kwachilendo kukukwera. chitseko cha valve.
Tsinde la Umboni Wophulika
13. Tsinde Lowonjezera
Ponena za valavu yophatikizika, tsinde yowonjezera ikhoza kuperekedwa ngati ntchito ya pansi 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 kumtunda wapamwamba.
