Fixed Ball Valve

Ndife akatswiri opanga ma valve omwe ali ndi ziphaso za ISO, API ndi CE. Tili ndi zida zopangira zapamwamba komanso gulu lonse la machitidwe owongolera. Timavomerezanso maoda a OEM ndi ODM, okhala ndi madongosolo ochepa osinthika. Zogulitsa zathu zodalirika zimatumizidwa padziko lonse lapansi ndipo zimatchuka kwambiri ndi makasitomala.

Kodi valavu ya mpira wokhazikika ndi trunnion ndi chiyani?

Ma valve okhazikika a Trunnion amapangidwa kuti azithamanga kwambiri komanso mapaipi akulu akulu. Poyerekeza ndi mavavu a mpira oyandama, mpirawo umatsekedwa m'malo mwake kudzera pa tsinde lapamwamba la valve ndi shaft yapansi ya trunnion. Amangozungulira kuti atsegule ndi kutseka osasunthika pakakakamiza. Kapangidwe ka trunnion kumatenga kuchuluka kwa kuthamanga kwamadzimadzi, kutsitsa bwino pampando wosindikiza. Kapangidwe kameneka kamapangitsa kuti ma valve okhazikika a mpira akhale okhazikika komanso okhazikika kuti azigwira ntchito nthawi yayitali m'mafakitale.

Kodi pali kusiyana kotani pakati pa valavu ya mpira wokhazikika ndi valavu yoyandama ya mpira?

Ili ndiye funso lomwe limafunsidwa pafupipafupi ndi ogula padziko lonse lapansi. Kusiyana kwakukulu kwagona pamapangidwe othandizira mpira komanso njira yonyamulira.

Mavavu a mpira oyandama alibe chithandizo chotsika cha trunnion. Kuthamanga kwa mapaipi kukakwera, sing'angayo amakankhira mpira mwamphamvu kumpando wakumunsi. Izi zimapanga mikangano yayikulu, torque yayikulu yogwiritsira ntchito komanso kuvala pamipando mwachangu. Mitundu yoyandama ndiyoyenera kukula pang'ono komanso kutsika kwapakatikati kogwirira ntchito.

Mavavu okhazikika a mpira wa trunnion amakonza mpirawo pamalo ake. Kupanikizika kumayendetsedwa ndi shaft ya trunnion ndi kunyamula thupi, osati mpando wosindikiza. Imakhala ndi torque yocheperako, kuwonongeka kwapampando pang'ono, kusindikiza kokhazikika komanso moyo wautali wautumiki. Kwa DN100 / NPS4 ndi mapaipi apamwamba kwambiri kapena opanikizika kwambiri, mavavu a mpira okhazikika nthawi zonse amakhala chisankho choyamba muukadaulo wamafakitale.

Makhalidwe Ofunika

Kodi mavavu a mpira osasunthika amagwiritsidwa ntchito pati?

Ma valve okhazikika a Trunnion amagwiritsidwa ntchito kwambiri m'mafakitale olemera omwe amafunikira kusindikiza kokhazikika komanso moyo wautali wautumiki. Mafakitale odziwika bwino amaphatikizapo mapaipi otumizira mafuta ndi gasi, malo opangira magetsi amafuta, malo opangira magetsi, ntchito zoyeretsera madzi, malo opangira mafuta achilengedwe komanso makina operekera madzi akutali m'mafakitale. Ndikoyenera makamaka kumalo ogwirira ntchito omwe ali ndi kuthamanga kwambiri, kuthamanga kwakukulu, kusinthasintha pafupipafupi komanso zofunikira zowonongeka za zero.

Ndi zipangizo ziti zomwe mumathandizira matupi a valve okhazikika ndi ziwalo zamkati?

Timapereka zinthu zosiyanasiyana za thupi ndi zamkati kuti zigwirizane ndi ntchito zosiyanasiyana. WCB carbon zitsulo ndiye kusankha kwathu muyezo mapaipi ambiri mafakitale, kupereka kulimba odalirika pa mtengo mpikisano. Pakuti ntchito ndi dzimbiri madzi kapena mpweya, ife kusankha CF8 (304) ndi CF8M (316) zosapanga dzimbiri kukana odalirika dzimbiri.

Timathanso kupeza zipangizo zapadera monga zitsulo zotsika kutentha ndi zitsulo za aloyi pazantchito zovuta, zovuta. Kwa mbali zamkati monga mpira ndi mipando ya valve, timatha kukonza zosakaniza zosiyanasiyana kutengera zomwe mukufunikira.

Ndi miyezo ndi ziphaso zotani zomwe mavavu anu okhazikika amatsata?

Mavavu athu onse a trunnion okhazikika amapangidwa motsatira miyezo yapadziko lonse ya API 6D ndi ASME B16.34. Fakitale yathu ili ndi ziphaso zathunthu za API, ISO ndi CE. Valavu iliyonse yomaliza imadutsa mayeso aukadaulo wa chipolopolo, kuyesa kulimba kwa mipando ndi kulimba kwa mpweya musanaperekedwe. Malipoti onse oyeserera ndi zikalata zotsimikizira zitha kuperekedwa kuti zithandizire kuwunika kwamakasitomala ndi chilolezo chamakasitomala.

Kodi ndisankhe chisindikizo chofewa kapena valavu yosindikizira yachitsulo?

Zimatengera sing'anga yamapaipi anu ndi kutentha kogwirira ntchito. Ma valve okhazikika okhazikika a mpira amatengera kusindikiza kwa PTFE kapena RPTFE, kukwaniritsa kutayikira kolimba kwa zero. Ndi abwino kwa madzi aukhondo, gasi ndi sing'anga yotentha yamafuta omwe ali ndi zofunikira zosindikizira.

Zitsulo zolimba zosindikizidwa zokhazikika za mpira zimatha kusintha kutentha, kuthamanga kwambiri komanso sing'anga yokhala ndi tinthu tating'ono tating'ono tolimba. Chitsulo chosindikizira zitsulo ndizitsulo sichimva kuvala komanso kutentha kwambiri, chomwe chimagwiritsidwa ntchito kwambiri pazovuta za petrochemical komanso kutentha kwapaipi.

Kodi ma valve okhazikika a mpira angakhale ndi magetsi kapena pneumatic actuators?

Inde, mokwanira customizable. Ma valve athu okhazikika a mpira amatha kufananizidwa ndi zida zamanja, ma pneumatic actuators, magetsi oyendetsa magetsi ndi ma hydraulic actuators. Chifukwa cha mawonekedwe othandizira a trunnion, torque yogwiritsira ntchito ndiyotsika kwambiri kuposa ma valve oyandama a mpira. Ikhoza kuchepetsa mtengo wa kasinthidwe ka ma actuators ndikuwonetsetsa kuti kutseguka ndi kutseka kokhazikika.

Kodi chitsimikizo chanu chamtundu ndi chiyani pambuyo pogulitsa?

Ma valve athu onse a trunnion okhazikika amasangalala ndi chitsimikizo chanthawi yayitali. Timapereka chithandizo chonse chaukadaulo, chiwongolero chokhazikitsa ndikukambirana pambuyo pakugulitsa. Timayang'ana kwambiri ubale wanthawi yayitali ndi makasitomala apadziko lonse lapansi, osati mapangano anthawi imodzi.
