Valavu yowotcherera ndi mtundu womwe umagwiritsidwa ntchito kwambiri, womwe umagwiritsidwa ntchito m'mafakitale osiyanasiyana.

Valve yowotcherera mpiraamapangidwa makamaka ndi valavu thupi, mpira thupi, valavu tsinde, kusindikiza chipangizo ndi zigawo zina. Vavu ikakhala pamalo otseguka, bowolo la gawolo limagwirizana ndi axis ya payipi, zomwe zimapangitsa kuti madzi azidutsa bwino. Vavu ikafunika kutsekedwa, mpirawo umayendetsedwa kuti uzizungulira pozungulira tsinde la valavu, kotero kuti bowo la mpirawo limakhala lolunjika pamayendedwe a payipi, potero amadula kutuluka kwamadzimadzi. Chipangizo chosindikizira chimatsimikizira kusindikizidwa kwa valve mu malo otsekedwa, kuteteza kutuluka kwa madzi.

Kotero, ubwino wogwiritsa ntchito ma valves a welded mpira ndi chiyani?

Choyamba, valavu ya mpira wamoto imakhala ndi zosindikizira zabwino. Zida zosindikizira zapamwamba zimagwiritsidwa ntchito pakati pa malo ndi mpando wa valve kuti ateteze bwino kutuluka kwamadzimadzi ndikuonetsetsa kuti dongosololi likuyenda bwino.

Kachiwiri, ndi yosavuta kugwiritsa ntchito. Kutsegula ndi kutseka kwa valavu ya welded mpira kumangofuna kusinthasintha tsinde la valve 90 madigiri, omwe ndi osavuta komanso ofulumira kugwira ntchito, ndipo amatha kukwaniritsa kutsegulira ndi kutseka mofulumira.

Komanso weldedvalavu ya mpirakukhala ndi mphamvu yothamanga kwambiri. Chifukwa chakuti kupyola-bowo la gawolo ndi lofanana ndi m'mimba mwake mwa payipi, kukana kwamadzimadzi omwe amadutsa mu valve ndi kochepa, ndipo mphamvu yothamanga imakhala yolimba, yomwe imatha kukwaniritsa kufunika kwa kuthamanga kwapamwamba. .

Kuphatikiza apo, flange ya valve yowotcherera imakhala ndi mawonekedwe ophatikizika, voliyumu yaying'ono, komanso kuyika kosavuta. Itha kuwotcherera mwachindunji paipi, kuchepetsa kugwiritsa ntchito zolumikizira, kutsitsa mtengo woyika komanso kuwopsa kwa kutayikira.

Potsirizira pake, ma valve opangidwa ndi mpira amakhala ndi moyo wautali wautumiki. Zida zapamwamba kwambiri komanso njira zopangira zapamwamba zimapangitsa kuti valavu ya mpira yowotcherera isakhale ndi dzimbiri, yosamva kuvala, komanso yotha kugwira ntchito mokhazikika m'malo ovuta.

Vavu ya Jinbin yakhala ikugwira ntchito yopanga mavavu kwa zaka 20 ndipo ndiyopanga mavavu amphamvu ku China. Ngati muli ndi zofunikira zina za valve, chonde siyani uthenga pansipa ndipo mudzalandira yankho mkati mwa maola 24. Tikuyembekezera kugwirizana nanu!
