Chidziwitso cha mavavu a pulagi

Ma valve olumikizira

Pulagi Valve ndi valavu yozungulira yozungulira kotala yomwe imagwiritsa ntchito pulagi yopindika kapena yozungulira kuyimitsa kapena kuyambitsa kuyenda. Pamalo otseguka, pulagi-ndimeyi ili pamzere umodzi ndi madoko olowera ndi otuluka a thupi la Valve. Ngati pulagi 90 ° yazunguliridwa kuchokera pamalo otseguka, gawo lolimba la pulagi limatchinga doko ndikuyimitsa kuyenda. Ma valve olumikizira ndi ofanana ndi ma valve a Mpira omwe amagwira ntchito.

Mitundu ya mavavu a pulagi

Mavavu a pulagi amapezeka mu mawonekedwe osapaka mafuta kapena mafuta komanso ndi masitaelo angapo otsegulira madoko. Doko la pulagi ya tapered nthawi zambiri imakhala yamakona anayi, koma imapezekanso ndi madoko ozungulira komanso madoko a diamondi.

Ma valve olumikizira amapezekanso ndi ma cylindrical plugs. Mapulagi a cylindrical amaonetsetsa kuti madoko akuluakulu amatseguka ofanana kapena okulirapo kuposa malo oyendera mapaipi.

Mavavu a pulagi opaka mafuta amaperekedwa ndi patsekeke pakati pa olamulira pamenepo. Bowoli limatsekedwa pansi ndipo limayikidwa ndi jekeseni wa sealant pamwamba. Chosindikiziracho chimabayidwa pabowo, ndipo Valve Yoyang'ana pansi pa jekeseniyo imalepheretsa chosindikizira kuti chisayendere mbali yakumbuyo. Mafuta opangira mafuta amakhala gawo lokhazikika la Valve, chifukwa amapereka mpando wosinthika komanso wosinthika.

Mavavu a pulagi osapaka mafuta amakhala ndi liner ya elastomeric kapena mkono, womwe umayikidwa pabowo la thupi. Pulagi yopukutidwa komanso yopukutidwa imakhala ngati mphero ndikukanikizira mkono pathupi. Chifukwa chake, manja osakhala achitsulo amachepetsa kukangana pakati pa pulagi ndi thupi.

Pulagi valve Disk

Ma doko a rectangular ndi mawonekedwe omwe amapezeka kwambiri pamadoko. Doko lamakona anayi limayimira 70 mpaka 100 peresenti ya dera lamkati la chitoliro.

Mapulagi ozungulira amakhala ndi kutseguka kozungulira kudzera papulagi. Ngati kutsegula kwa doko kuli kofanana kapena kukulirapo kuposa m'mimba mwake mwa chitoliro, doko lathunthu limatanthawuza. Ngati kutsegulira kuli kochepa kuposa m'mimba mwake mwa chitoliro, doko lozungulira lokhazikika limatanthawuza.

Pulagi ya doko la diamondi ili ndi doko lokhala ngati diamondi kudzera pa pulagi ndipo ndi mitundu yodutsa yoletsedwa ndi venturi. Kapangidwe kameneka ndi koyenera pautumiki wa throttling.

Ma valavu a pulagi

Pulagi Valve itha kugwiritsidwa ntchito mumitundu yosiyanasiyana yamadzimadzi ndipo imagwira ntchito bwino pamakina osasunthika. Zotsatirazi ndi zina zomwe zimagwiritsidwa ntchito ndi ma plug valves:

• Ntchito za mpweya, mpweya, ndi nthunzi
• Njira zamapaipi achilengedwe a gasi
• Makina opangira mafuta
• Chotsani ku ntchito zopanikizika kwambiri

Ubwino ndi Kuipa kwa mavavu a pulagi

Ubwino:

• Kuzimitsa kotala mwachangu
• Pang'ono kukana kuyenda
• Zocheperako kukula kuposa mavavu ena ambiri

Zoyipa:

• Imafunikira mphamvu yayikulu kuti igwire ntchito, chifukwa cha kukangana kwakukulu.
• NPS 4 ndi mavavu akuluakulu amafuna kugwiritsa ntchito actuator.
• Doko lochepetsedwa, chifukwa cha pulagi yotchinga.
