5 Zolakwika Zodziwika za Pneumatic Control Valve:

1. The Control Valve sikugwira ntchito

Choyamba tsimikizirani ngati mphamvu ya gasi ili yabwinobwino, pezani kulephera kwa gwero la gasi.Ngati kuthamanga kwa mpweya kuli kwabwinobwino, dziwani ngati amplifier ya poyizoni kapena chosinthira mpweya chili ndi zotulutsa.

2. Kutsekeka kwa valve

Zikatero, mukhoza kutsegula mwamsanga, kutseka Mzere wachiwiri kapena valavu yolamulira, kotero kuti katundu wabedwa kuchokera ku mzere wachiwiri kapena valavu yolamulira inali yothamanga.Kuphatikiza apo, muthanso kuwongolera tsinde ndi mbande za chitoliro, kuwonjezera pa kukakamiza kwa siginecha, tsinde labwino komanso loyipa lozungulira, kuti tsinde la valve pachimake kung'anima.

Ngati sangathe kuthetsa vutoli, akhoza kuwonjezera mpweya gwero kuthamanga, kuwonjezera pagalimoto mphamvu kusuntha mmwamba ndi pansi mobwerezabwereza kangapo, angathe kuthetsa vutoli.Ngati akadali sangathe kusuntha, ndiye ayenera kuchita kulamulira valavu disassembly processing, ndithudi, ntchito imeneyi amafuna amphamvu luso luso, ziyenera kuchitidwa mothandizidwa ndi akatswiri ndi luso ogwira, apo ayi zotsatira zoopsa kwambiri.

3. Vavu kutayikira

Kutaya kwa valve yolamulira pneumatic nthawi zambiri kumayambitsidwa ndi kutuluka kwamkati kwa valve yolamulira, kutuluka kwa kulongedza ndi kutuluka kwa valve core ndi mpando wa valve.

3.1 Kutuluka kwa mkati

Vavu tsinde kutalika kusapeza, mpweya valavu tsinde yaitali kwambiri, tsinde mmwamba (kapena pansi) mtunda sikokwanira, kuchititsa kusiyana pakati SPOOL ndi valavu mpando, sangathe kukhudzana kwathunthu,

3.2 Kutulutsa Kutayikira

Pofuna kuti stuffing mosavuta katundu, chamfer pamwamba pa stuffing bokosi, kuika zitsulo kuteteza mphete ndi yaing'ono kukokoloka kukana kusiyana pansi pa stuffing bokosi, zindikirani kuti kukhudzana pamwamba pakati poteteza mphete ndi stuffing sangathe ndege yozungulira.

Pofuna kupewa stuffing kuti anakankhira kunja ndi sing'anga kuthamanga.Pamwamba pa bokosi loyikapo zinthu ndi gawo lolumikizirana loyika zinthu liyenera kumalizidwa kuti lipititse patsogolo kumaliza ndikuchepetsa kuvala.Ma graphite osinthika amasankhidwa ngati chodzaza chifukwa cha kulimba kwake kwa mpweya wabwino, mphamvu yolimbana pang'ono, kusintha pang'ono pakugwiritsa ntchito kwanthawi yayitali, kuvala pang'ono ndi kung'ambika, kusungika kosavuta, komanso kukana kukakamiza ndi kukana kutentha ndikwabwino chifukwa mphamvu yakukangana sichita. kusintha pambuyo gitala bawuti ndi omangika kachiwiri wopanda dzimbiri za mkati TV, ndi tsinde ndi stuffing bokosi kukhudzana mkati zitsulo si pitting kapena dzimbiri.

Mwanjira imeneyi, tetezani bwino chisindikizo cha tsinde la valve, kuonetsetsa kudalirika kwa chisindikizo chonyamula, moyo wautumiki umakhalanso bwino kwambiri.

3.3 Valve Core, Valve Seat Deformation Leakage

Kusankhidwa kwa zipangizo zosagwira dzimbiri, kukhalapo kwa pitting, trachoma ndi zolakwika zina za mankhwala kuti zithetsedwe.Ngati kupindika kwa pachimake valavu ndi mpando sikuli koopsa kwambiri, sandpaper yabwino ingagwiritsidwe ntchito pogaya, kuchotsa zotsalira, kukonza kusindikiza, kupititsa patsogolo ntchito yosindikiza.Ngati kuwonongeka kuli kwakukulu, muyenera kusintha valavu yatsopano.

4. Oscillates

Kuuma kwa kasupe kwa valve yolamulira sikukwanira, chizindikiro chotuluka cha valve yolamulira sichikhazikika ndipo chimasintha mofulumira, chomwe chimayambitsa mosavuta kuwongolera Valve oscillation.

Monga zomwe zimayambitsa oscillation ndizosiyanasiyana, ndikofunikira kusanthula konkire kwa zovuta zinazake.Mwachitsanzo, valavu yosinthira yokhala ndi kasupe wamkulu wokhazikika imasankhidwa, ndipo mawonekedwe opangira pisitoni amagwiritsidwa ntchito m'malo mwake.

Chitoliro ndi maziko akugwedezeka mwamphamvu, ndipo kusokoneza kugwedezeka kungathe kuthetsedwa mwa kuwonjezera chithandizo.Sinthani mawonekedwe osiyanasiyana a valve yolamulira.Kugwira ntchito potsegula pang'ono chifukwa cha oscillation, kumayambitsidwa ndi kusankha kosayenera, makamaka, chifukwa mphamvu ya valve yothamanga C mtengo ndi yaikulu kwambiri, iyenera kusankhidwanso, kusankha mphamvu yothamanga ya C mtengo ndi yaying'ono kapena kugwiritsa ntchito sub- kuwongolera kwamtundu kapena kugwiritsa ntchito valavu ya makolo kuti mugonjetse valavu yowongolera yomwe ikugwira ntchito potsegula pang'ono chifukwa cha kugwedezeka.

5. Phokoso

5.1 Njira Yothetsera Phokoso la Resonance

Pokhapokha pamene kumveka kwa valavu yolamulira, pali mphamvu yowonjezera ndipo imapanga ma decibel oposa 100 a phokoso lamphamvu.Zina zimawonetsa kugwedezeka kwamphamvu, phokoso si lalikulu, kugwedezeka kwina ndi kofooka, koma phokoso ndi lalikulu kwambiri;kugwedezeka kwina ndi phokoso ndizokulirapo.Phokosoli limatulutsa phokoso la monotonic pafupipafupi pakati pa 3000 ndi 7000 Hz.Mwachiwonekere, pochotsa phokosolo, phokosolo lidzazimiririka mwachibadwa.

5.2 Kuchepetsa Phokoso la Cavitation

Cavitation ndiye gwero lalikulu la phokoso la hydrodynamic.Pamene cavitation ichitika, kuwirako kumaphulika ndikutulutsa kuthamanga kwambiri, zomwe zimapangitsa kuti pakhale chipwirikiti cham'deralo ndi phokoso la cavitation.Phokosoli limakhala ndi ma frequency osiyanasiyana ndipo limatulutsa phokoso la lattice lofanana ndi lomwe limapangidwa ndi madzi okhala ndi miyala.Kuchotsa ndi kuchepetsa cavitation ndi njira yabwino yothetsera ndi kuchepetsa phokoso.

5.3 Gwiritsani Ntchito Njira Yothina Khoma

Kugwiritsa ntchito chubu cholimba-mipanda ndi imodzi mwa njira zothanirana ndi mabwalo amawu.Kugwiritsa ntchito khoma lopyapyala kumatha kukulitsa phokoso ndi 5 DB, kugwiritsa ntchito chubu cholimba cha khoma kumatha kuchepetsa phokoso ndi 0 ~ 20 DB.Kuchuluka kwa khoma la mainchesi omwewo, kukula kwake kwa makulidwe a khoma lomwelo, kumapangitsanso kuti phokoso lichepetse.Kwa mapaipi a DN200 okhala ndi khoma makulidwe a 6.25,6.75,8,10,12.5,15,18,20 ndi 21.5 mm, phokosolo limatha kuchepetsedwa ndi-3.5, -2 (ie kuchuluka), 0,3,6,8, 11, 13 ndi 14.5 DB motsatana.Zoonadi, pamene khomalo likukulirakulira, mtengo wake umakwera.

5.4 Gwiritsani Ntchito Njira Yoyamwitsa Zomveka

Iyinso ndi njira yodziwika bwino, yothandiza kwambiri yopangira mawu.Zinthu zotulutsa phokoso zitha kugwiritsidwa ntchito kutsekereza gwero la phokoso ndi chitoliro kuseri kwa valavu.Ndikofunika kunena kuti mphamvu yochepetsera phokoso imasiya kulikonse komwe zinthu zotulutsa mawu zimapakidwa ndikugwiritsa ntchito machubu amipanda, chifukwa phokoso limatha kuyenda mtunda wautali kudzera mukuyenda kwamadzimadzi.Njirayi ikugwiritsidwa ntchito pamene phokoso la phokoso silili lokwera kwambiri ndipo kutalika kwa chitoliro sikutalika kwambiri, chifukwa ndi njira yokwera mtengo.

5.5 Series Silencer Njira

Ndizoyenera kuletsa phokoso la aerodynamic.Ikhoza kuthetsa phokoso mkati mwa madzimadzi ndikuletsa phokoso la phokoso lomwe limaperekedwa kumalo olimba a malire.Njirayi ndi yothandiza kwambiri komanso yotsika mtengo pomwe kuchuluka kwa kuthamanga kwachulukidwe kumakhala kwakukulu kapena kuchuluka kwa kupanikizika kumatsika musanayambe komanso pambuyo pake.Kugwiritsa ntchito mayamwidwe amtundu wa silencer kumatha kuchepetsa kwambiri phokoso.Zolinga zachuma, komabe, nthawi zambiri zimakhala zocheperako pafupifupi 25 DB.

5.6 Njira yotsekera

Gwiritsani ntchito mpanda, nyumba ndi nyumba kuti mulekanitse gwero la phokoso kuchokera kumadera akunja mpaka malire ovomerezeka.

5.7 Series Throttling

Pamene chiŵerengero cha kuthamanga kwa valve yolamulira ndipamwamba (△ P / p 1≥0.8), njira yotsatizana yotsatizana imagwiritsidwa ntchito kufalitsa kutsika kwapakati pa valve yolamulira ndi chinthu chokhazikika kumbuyo kwa valve.DIFFUSERS, zoletsa porous, mwachitsanzo, ndi njira zothandiza kwambiri zochepetsera phokoso.Kuti muthe kugwiritsa ntchito bwino ma diffuser, chotulutsa (mawonekedwe olimba ndi kukula kwake) chiyenera kupangidwa molingana ndi kuyika kwa chidutswa chilichonse, kuti phokoso lopangidwa ndi valavu likhale lofanana ndi lomwe limapangidwa ndi diffuser.

5.8 Gwiritsani Ntchito Phokoso Lochepa

Valve yotsika yaphokoso molingana ndi madzimadzi kudzera mu spool, mpando wa tortuous flow path (multi-channel, multi-channel) pang'onopang'ono pang'onopang'ono kuti mupewe mfundo iliyonse panjira yotulutsa supersonic.Pali mitundu yosiyanasiyana, mitundu yosiyanasiyana ya valve yotsika phokoso (pali dongosolo lapadera) logwiritsidwa ntchito posankha.Pamene phokoso silili lalikulu kwambiri, sankhani valavu yapansi ya phokoso, ikhoza kuchepetsa phokoso 10 ~ 20 DB, iyi ndi valve yotsika kwambiri ya phokoso.
