Wopereka Ma Valve Omwe Mungakhulupirire
Onani ma valvendi imodzi mwazinthu zotentha za NSW valves. Tili ndi zaka zopitilira 20 pakupanga ma valve. Yang'anani miyezo yopangira ma valve molingana ndi API 6D, BS 1868, API 594, etc. Ma valve athu oyendera mbale, ma valve oyendayenda, ma piston check valves, axial check valves ndi tilting disc check valves amalandiridwa bwino ndi makasitomala apadziko lonse ndi apakhomo.
Momwe Mungasankhire Cheki Vavu
NSW ndi fakitale yapadera yopanga ma valve. Tili ndi zida zathu zopangira ma valve pachipata, zida zopangira ma valve ndi akatswiri dipatimenti yowongolera khalidwe la valavu. Tikukupatsirani mtengo wa fakitale yowunikira ma valve
Kugulitsa Kwachangu Chongani Zinthu Zovala Mavavu
API 6D Full Port Swing Check Valve imatsimikizira kuwongolera koyenda kwamafuta, gasi, ndi mapaipi a petrochemical. Mapangidwe ake odzaza amachepetsa kupsinjika, kumapangitsa kuyenda bwino, ndikulepheretsa kubwereranso kudzera pa swing disc makina.
BS 1868 Swing Check Valve imatsimikizira kupewa kubweza kodalirika mumafuta, gasi, ndi mapaipi amafuta. Mogwirizana ndi miyezo ya BS 1868, mawonekedwe ake olimba a swing disc amatsimikizira kutsekedwa mwachangu, kuchepetsa kutsika kwamphamvu komanso kuwopsa kwa kutayikira.
API 594 Dual Plate Check Valve imalepheretsa kubwereranso m'mapaipi amafuta, gasi, ndi mankhwala. Mapangidwe ake ophatikizika amitundu iwiri amatsimikizira kutsekedwa mwachangu, kuchepetsa kutsika kwamphamvu komanso kutayikira. Zoyenera kuziyika zopingasa / zoyima, zopepuka, zosakonza bwino

Mapangidwe ake opendekeka a disc amatsimikizira kutsekedwa mwachangu, kuchepetsa kutsika kwamphamvu komanso kuopsa kwa nyundo yamadzi. Wopangidwa kuchokera ku kaboni/chitsulo chosapanga dzimbiri, Imapirira kupsinjika kwakukulu, malo otentha kwambiri.
Kodi Check Valve ndi chiyani
Valve yowunikira ndi chida chofunikira chowongolera madzimadzi, chomwe chimagwiritsidwa ntchito makamaka kuteteza sing'anga kuti isabwererenso mupaipi.
Valve yowunikira, yomwe imadziwikanso kuti valavu yosabwerera, valavu imodzi, valavu ya reflux kapena valavu yodzipatula, imatanthawuza valavu yomwe mbali zake zotsegula ndi zotseka ( valve flap ) zimakhala zozungulira ndipo zimadalira kulemera kwawo ndi kupanikizika kwapakatikati kuti apange kayendetsedwe kake kuti atseke kumbuyo kwapakati. Ntchito yake yayikulu ndikulola kuti madzimadzi aziyenda mbali imodzi yokha. Madziwo akabwerera m'mbuyo, valavu ya valve imatseka yokha, motero imadula njira yothamanga ndikuletsa kuwonongeka chifukwa cha kubwereranso.
Momwe Mungasankhire Wopanga Mavavu Olondola Ndi Opereka

Kodi Mitundu Yama Check Valves Ndi Chiyani
Kugawika kwamapangidwe a ma cheki ma valve
Malinga ndi kapangidwe, iwo akhoza kugawidwa mu mitundu itatu:
1. Kwezani ma valve cheke
Ilo lagawidwa mu ofukula ndi yopingasa mitundu.
2. Swing ma valve cheke
Amagawidwa m'magulu amodzi, awiri-flap ndi mitundu yambiri.
3. Mavavu a gulugufe
Ndizowongoka.
Yang'anani gulu la zinthu za valve
- Valve yowunikira chitsulo
- Valve yoyang'ana mkuwa
- Valovu yoyang'ana zitsulo zosapanga dzimbiri
- Carbon steel check valve
- Valve yoyeserera yachitsulo yopangidwa
Yang'anani ntchito za valve
- DRVZ valavu yoyang'ana chete
- DRVG valavu yoyang'ana chete
- NRVR valavu yoyang'ana chete
- SFCV rubber flap check valve
- DDCV double flap check valve
Kugawa ndi njira yoyika ma valavu
Chovala chowongolera cha swing:
Disiki ya valve ya swing check valve imakhala yofanana ndi disc ndipo imazungulira kuzungulira shaft yozungulira ya mpando wa valve. Chifukwa njira yomwe ili mkati mwa valavu imayendetsedwa bwino, kukana koyenda kumakhala kochepa kuposa kwa valve yokweza. Ndizoyenera nthawi zazikuluzikulu zokhala ndi kutsika kochepa komanso kusintha kosasintha.
Chovala chowongolera chokweza:
Valve yowunika yomwe valavu yake imayenda motsatira mzere woyima wapakati pa thupi la valavu. Valve yowunikira imatha kukhazikitsidwa patope yopingasa. Kumtunda kwa diski ya valve ndi kumunsi kwa chivundikiro cha valve kumakonzedwa ndi manja otsogolera. Manja owongolera ma valavu amatha kukwezedwa momasuka ndikutsitsidwa mumanja owongolera ma valve. Pamene sing'anga ikuyenda pansi pamtsinje, valavu ya valve imatsegulidwa ndi kukankhira kwa sing'anga.
Valve yowunikira ma disc:
Valve yoyang'ana momwe diski imazungulira mozungulira shaft ya pini pampando wa valve. Valve yowunikira ma disc ili ndi mawonekedwe osavuta ndipo imatha kukhazikitsidwa pamapaipi opingasa, ndipo ntchito yake yosindikiza ndiyosauka.
Valve yowunikira mapaipi:
Valve yomwe disc imayenda pamzere wapakati wa thupi la valve. Vavu yoyang'ana mapaipi ndi mtundu watsopano wa valve. Ndi yaying'ono kukula kwake, yopepuka kulemera kwake, ndipo ili ndi luso lokonza bwino. Ndi imodzi mwa njira zachitukuko za valve cheke. Komabe, coefficient yamadzimadzi yolimbana ndi madzi ndi yayikulu pang'ono kuposa ya swing check valve.
Valve yowunikira compression:
Valve iyi imagwiritsidwa ntchito ngati madzi opangira boiler komanso valavu yodulira nthunzi. Ili ndi ntchito zophatikizika za valavu yokweza ndi valavu yoyimitsa kapena valavu. Kuonjezera apo, pali ma valve owunika omwe sali oyenerera kuyika pompani, monga ma valve pansi, ma check valves a masika, ndi ma check valves a Y.
Chifukwa Chosankha Chekeni Vavu
Zifukwa zazikulu zakusankha valavu yoyang'anira ndikuletsa kubweza kwamadzi, kuteteza zida ndikuwongolera magwiridwe antchito. Ntchito yayikulu ya valavu yoyang'anira ndikuletsa kubwereranso kwamadzi mu payipi ndikuwonetsetsa kuti madziwo amatha kuyenda mbali imodzi. Kapangidwe kameneka kamateteza bwino zida kuti zisawonongeke, makamaka m'malo ogwirira ntchito omwe ali ndi kuthamanga kwambiri, kutentha kwambiri kapena zowononga. Valve yowunikira imatha kuwonetsetsa kuti madziwo akuyenda munjira yopangidwira ndikupewa kuwonongeka kwa zida chifukwa chakubwerera.
