Kuwunika kwa Ubwino ndi Kuipa kwa Mitundu Isanu Yodziwika ya Mavavu 2

3. Vavu ya Mpira

Vavu ya mpira idasinthika kuchokera ku valavu ya pulagi. Gawo lake lotsegula ndi lotseka ndi gawo, ndipo gawolo limazungulira 90 ° mozungulira tsinde la valve kuti likwaniritse cholinga chotsegula ndi kutseka. Vavu ya mpira imagwiritsidwa ntchito makamaka pamapaipi kuti adule, kugawa, ndikusintha njira yoyendetsera sing'anga. Valavu ya mpira yopangidwa ndi kutsegulira kooneka ngati V imakhalanso ndi ntchito yabwino yoyendetsera kayendetsedwe kake.

Fakitale ya valavu ya TWS imapereka valavu yagulugufe yokhazikika yokhazikika YD37A1X3-16Q, valavu yagulugufe yokhazikika kawiriChithunzi cha D34B1X3-16Q, Valavu yagulugufe yamtundu wa Double flanged eccentric molingana ndi Ser.13 kapena mndandanda wa 14, BS5163 / F4 / F5 / ANSI CL150 mphira wokhala pachipata valavu, Y-strainer, valve balancing, kumbuyo kumbuyo blocker.

3.1 Ubwino:

① Ili ndi kukana kotsika kwambiri (pafupifupi 0).

② Popeza sichidzakakamira pakugwira ntchito (palibe mafuta), itha kugwiritsidwa ntchito modalirika pazambiri zowononga komanso zamadzimadzi zowira pang'ono.

③ Ikhoza kukwaniritsa kusindikiza kwathunthu mkati mwa kuthamanga kwakukulu ndi kutentha.

④ Itha kukwaniritsa kutsegula ndi kutseka mwachangu. Nthawi yotsegula ndi yotseka yazinthu zina ndi masekondi 0.05 mpaka 0.1, kuwonetsetsa kuti zitha kugwiritsidwa ntchito pamabenchi oyesera. Mukatsegula ndi kutseka valve mwamsanga, palibe zotsatira pa ntchito.

⑤ Gawo lotsekera lozungulira limatha kukhazikika pamalire.

⑥-- Sing'anga yogwirira ntchito imasindikizidwa modalirika pa valve.

Q⑦ Pamene valavu yatsegulidwa kwathunthu ndi kutsekedwa kwathunthu, malo osindikizira a malo ndi mpando wa valve amasiyanitsidwa ndi sing'anga. Choncho, sing'anga yomwe ikuyenda mu valve pa liwiro lalikulu sichidzachititsa kukokoloka kwa malo osindikizira.

⑧ Ili ndi mawonekedwe ophatikizika komanso kulemera kwake. Ikhoza kuonedwa kuti ndiyo njira yabwino kwambiri ya valve yochepetsera kutentha kwapakati.

⑨ Thevalavuthupi ndi symmetrical. Makamaka pamapangidwe amtundu wa valavu wowotcherera, amatha kupirira kupsinjika kwapaipi.

⑩ Gawo lotseka limatha kupirira kusiyana kwakukulu pakutseka.

⑪ Vavu ya mpira yokhala ndi valavu yotsekedwa mokwanira imatha kukwiriridwa mobisa, kuteteza zida zamkati za valavu kuti zisawonongeke. Utumiki wake wochuluka ukhoza kufika zaka 30, ndikupangitsa kuti ikhale valve yabwino kwambiri yamapaipi amafuta ndi gasi.

3.2 Zoyipa:

① Chachikuluvalavumphete yosindikizira mpando ya valve ya mpira ndi polytetrafluoroethylene (PTFE). Imalowetsa pafupifupi zinthu zonse zamakhemikolo ndipo ili ndi mawonekedwe omveka bwino monga kugundana kwapang'ono, kugwira ntchito kosasunthika, kukana kukalamba, kutentha kosiyanasiyana, komanso kusindikiza kwabwino kwambiri. Komabe, zinthu zakuthupi za PTFE, kuphatikiza kuchuluka kwapang'onopang'ono, kukhudzika kwa kuzizira, komanso kusayenda bwino kwamatenthedwe, zimafuna kuti mapangidwe a chisindikizo cha mpando wa vavu ayenera kuchitidwa mozungulira zinthu izi. Chifukwa chake, zinthu zosindikizira zikalimba, kudalirika kwa chisindikizo kumasokonekera. Komanso, kutentha kukana kalasi ya PTFE ndi otsika, ndipo angagwiritsidwe ntchito pa kutentha m'munsimu 180 ° C. Kutentha kukadutsa mtengowu, zinthu zosindikizira zidzakalamba. Poganizira kugwiritsidwa ntchito kwa nthawi yayitali, nthawi zambiri imagwiritsidwa ntchito pa 120 ° C.

② Kayendetsedwe kake kachitidwe kake kamakhala koyipa kwambiri kuposa valavu yapadziko lonse lapansi, makamaka mavavu a pneumatic (kapena ma valve amagetsi.

5. Pulagi Vavu

Valavu ya pulagi imatanthawuza valavu yozungulira momwe gawo lotsekera limakhala ngati plunger. Pozungulira 90 °, ndime yotsegula pa pulagi imapangidwa kuti ilankhule kapena kupatukana ndi ndime yotsegula pa thupi la valve, kukwaniritsa kutsegula kapena kutseka kwa valve. Amatchedwanso tambala, stopcock, kapena rotary gate. Maonekedwe a pulagi akhoza kukhala cylindrical kapena conical. Pali mitundu yambiri yake, kuphatikiza mtundu wowongoka, wanjira zitatu, ndi njira zinayi. Mfundo yake ndi yofanana ndi ya valve ya mpira.

5.1 Ubwino:

① Ndioyenera kugwira ntchito pafupipafupi, ndikutsegula ndi kutseka mwachangu komanso mopepuka.

② Kukana kwamadzimadzi kumakhala kochepa.

③ Ili ndi kapangidwe kosavuta, voliyumu yaying'ono, kulemera kwake, ndipo ndiyosavuta kuyisamalira.

④ Ili ndi ntchito yabwino yosindikiza.

⑤ Osaletsedwa ndi njira yokhazikitsira, njira yoyendetsera sing'anga imatha kukhala yosasunthika.

⑥ Palibe kugwedezeka, ndipo phokoso ndilochepa.

5.2 Zoyipa:

⑦ Malo osindikizira ndi aakulu kwambiri, zomwe zimapangitsa kuti ma torque achuluke komanso osatha kusinthasintha.

⑧ Kukhudzidwa ndi kulemera kwake, kukula kwa ma valve awiri ndi ochepa.

Pogwiritsidwa ntchito kwenikweni, ngati valavu yayikulu ikufunika, pulojekiti yowonongeka iyenera kugwiritsidwa ntchito, yomwe ingakhudze kusindikiza.

Zambiri, zitha kukhala zaulere kulumikizanaTWS valvefakitale.
