(a) Makhalidwe ogwiritsira ntchito valve yodulidwa
Mphepete mwa mawonekedwe a torque ya valve yodulidwa ndi yokwera pakati komanso yotsika mbali zonse.
Chifukwa cha izi ndi chakuti, pamene valavu yodulidwa ili pakati, madziwo amatsekedwa ndi gulugufe mbale, circumvent gulugufe mbale liquidity, adzapangidwa mbali zonse za gulugufe mbale akuzungulira panopa, gulugufe. mbale imapanga mphindi yakutsogolo yamadzi, mphindi imayendetsedwa kuti ichotse mbale yagulugufe. Ndi kutsegula kapena kutseka kwa gulugufe mbale, chikoka cha madzi pa mbali ziwiri za gulugufe chifukwa cha vortex otaya ndi ang'onoang'ono ndi ang'onoang'ono, mpaka mphepo yamkuntho itatha, pa nthawi ino kukana kukangana kwa gulugufe mbale ndi ang'onoang'ono. ndi zing'onozing'ono, zomwe zimapangitsa kuti pakhale malo apamwamba, makhalidwe otsika a mbali ziwiri za chithunzicho. Ma torque enieni ogwiritsira ntchito potsegulira valavu yachipata ndi yayikulu kuposa yomwe ikutseka. Chifukwa chachikulu ndi chakuti hydrodynamic makokedwe chifukwa cha madzi pa mbale agulugufe nthawi zonse kwa kutseka ngodya.
Mphamvu yayikulu kwambiri ya valavu yoyimitsa yosatsekedwa ndi hermetically imapezeka pamalo apakati, pomwe torque yayikulu kwambiri ya valavu yotsekedwa ndi hermetically imachitika pomwe valavu yachipata yatsekedwa, makamaka chifukwa cha torque yokakamiza yosindikiza.
Mpando wa valavu wa valavu yodulidwa pokhapokha poyenda mozungulira, diski yake ndi mpando wokhawokha sizimatsekedwa mphamvu. Kuti apange malo olondola a disk (kutha pa malo otchulidwa), njira imodzi imafuna chochepetsera chowonjezera ndi mphamvu yotseka pampando. Pambuyo pochepetsanso mapulaneti owonjezera, liwiro la angular likhoza kuwonjezeka mpaka maulendo angapo, pamene torque yeniyeni yogwiritsira ntchito imachepetsedwa. Izi zimalola kuti machitidwe ena enieni ogwiritsira ntchito valve odulidwa (monga kutembenuka kwathunthu ndi torque yeniyeni yogwiritsira ntchito) kukhala pafupi ndi ma valve ena a zipata, zomwe zimagwirizana ndi kugwiritsa ntchito zipangizo zamagetsi.
Kuti atseke mokakamiza valavu yodulidwa, malo ake otseka ayenera kutsimikiziridwa ndi torque yeniyeni yomwe ikukwera pamtengo wokhazikika.
(2) Makhalidwe ogwiritsira ntchito ma valve Mawonekedwe a torque:
Chiwonetsero cha mawonekedwe a torque ya valavu ya mpira ndi chofanana kwambiri ndi valavu yodulidwa, chifukwa chachikulu ndi chifukwa cha kukopa kwamadzimadzi komwe kumachitika chifukwa cha kusintha kwa kulowa mu gawolo. Zotsatira za mvula yamkuntho zimachepa pang'onopang'ono ndi kutsegula kapena kutseka kwa valve.
Vavu ya mpira kuchokera pakutsegula mpaka kutseka, njira yozungulira mpando wa vavu ndi 90%, valavu ya mpira kukhazikitsa malire amakina. Gawo loyambira kapena lotseka la valve ya mpira liyenera kutsimikiziridwa ndi kayendetsedwe ka kayendetsedwe ka mpando wa valve, kotero kuti valve ya mpira imayikidwa molingana ndi kayendetsedwe ka kayendetsedwe kake.
Kukonzekera kwatsiku ndi tsiku kwa valve valve yokonza tsiku ndi tsiku kusungirako valavu ya mpira kumayenera kukhala yopanda madzi, chinyezi, madzi, ndi chivundikiro cha flange mwamphamvu, chosungidwa kwa miyezi 12 ya valve yachipata, ntchito iyenera kuyesedwanso kuti ikhale yokhazikika. Ngati kudontha kwakung'ono kumapezeka pazambiri zomwe zimagwiritsidwa ntchito, mtedza wa tsinde la valve ukhoza kumangika pang'ono mpaka kutayikirako kuthetsedwa, osamangikanso. Ma valve ambiri a mpira wa flange amagwiritsa ntchito tetrafluoride (PTFE) ngati zisindikizo za mphira, valavu ya mpira wa flange powotcherera zitsulo. Ngati valavu ya mpira wa chitoliro ikufunika kutsukidwa, samalani kuti musawononge mphete yosindikizira ndi kutayikira panthawi ya disassembly.
Valve ya mpira wa flange iyenera kukhala yopanda madzi, yotsimikizira chinyezi, yopanda madzi ikasungidwa, ndipo chophimba cha flange chimakhala cholimba, chosungidwa kuposa miyezi 12 ya valve yachipata, ntchito iyenera kuyesedwanso kuti itsimikizire kukhazikika kwabwino. Ngati kudontha kwakung'ono kumapezeka pazambiri zomwe zimagwiritsidwa ntchito, mtedza wa tsinde la valve ukhoza kumangika pang'ono mpaka kutayikirako kuthetsedwa, osamangikanso. Ma valve ambiri a mpira wa flange akugwiritsa ntchito tetrafluoride (PTFE) ngati zisindikizo za mphira, valavu ya mpira wa flange powotcherera zitsulo. Ngati valavu ya mpira wa chitoliro ikufunika kutsukidwa, samalani kuti musawononge mphete yosindikizira ndi kutayikira panthawi ya disassembly.

1, dzina la fakitale limasonyeza kuti valavu ya mpira wa flange imaloledwa kugwira ntchito pa kutentha kwakukulu poyerekeza ndi kutentha kochepa kwa kalasi ya King Kong.
2, valavu ya mpira wa flange yokhala ndi PTFE kapena RTFE zakuthupi zothamanga kwambiri pachipata valavu ndi zisindikizo zama hydraulic, kutentha kogwira ntchito kuyenera kukhala pakati pa -290C mpaka 2000C. Kutentha kogwira ntchito kwa mitundu ina ya ma valve othamanga kwambiri ndi zisindikizo za hydraulic ziyenera kufufuzidwa ndi fakitale ya KI.
3, m'mimba mwake mwadzina la kalasi ya valve (PN), ikhoza kusonyeza kuti valavu mu chikhalidwe cha kutentha ndipamwamba kwambiri. (Mwachitsanzo: PN4.0, kusonyeza kuti kutentha kwa ntchito -290C ~ 380C pambuyo pa kupanikizika kwakukulu kwa 40 Bar (4.0MPa)).

Chimodzi, valavu ya mpira yoyandama
Mpira wa valve umayandama mmwamba ndi pansi, chifukwa cha kukakamizidwa kwa zinthu zogwirira ntchito, mpirawo ukhoza kutulutsa cholumikizira china ndi chomangika pamtunda wolowera, kuwonetsetsa kuti kutsekeka kutha kusindikiza. Kapangidwe ka ma valve oyandama ndi osavuta, ophatikizika, koma mpirawo umatengera zowulutsa zonse polowera ndi mphete yosindikizira, kotero tiyenera kumvetsetsa mphete yosindikiza mphira imatha kupirira ntchito ya mpira sing'anga. Kapangidwe kameneka kakugwiritsidwa ntchito kwa mavavu apakatikati ndi otsika.
Awiri, valavu ya mpira yokhazikika
Mpira valavu mpira ndi mosalekeza, pambuyo mphamvu si kusuntha. Ma valve okhazikika a mpira amabwera ndi ma valve osinthasintha othamanga kwambiri. Pambuyo pa kukakamiza kwazinthu zogwirira ntchito, valve yothamanga kwambiri ya chipata imasunthidwa, kotero kuti mphete yosindikizira imakanikizidwa mwamphamvu pa mpira kuti zitsimikizire kuti zolimba. Nthawi zambiri mkati ndi mpira nsalu, shaft m'munsi imakhala ndi zonyamula zozungulira, torque yaying'ono yowongolera, yoyenera kuthamanga kwambiri komanso thupi laling'ono la valve. Pofuna kuchepetsa torque ya valve ya mpira ndikuwonjezera kudalirika kwa chisindikizo, valavu yosindikizidwa ya skeleton yawonekera m'zaka zaposachedwa. Sikuti kubetcha mafuta apadera pakati pa pamwamba kuti apange wosanjikiza wamafuta, omwe amathandizira kumangika ndikuchepetsa ma torque enieni. Ndizoyenera kwambiri valavu ya mpira yokhala ndi kuthamanga kwambiri komanso m'mimba mwake yaying'ono.
Chachitatu, valavu ya mpira
Mpira wa valavu ya mpira ukugwedezeka. Mpira ndi mkulu kuthamanga pachipata valavu chisindikizo mphete amapangidwa ndi zitsulo gulu zipangizo, kusindikiza kuthamanga ndi lalikulu kwambiri, kudalira zinthu za kukakamizidwa yekha waposa zofunika kutseka, kufunika kuonjezera mphamvu kunja. Valavu yachipata ichi ndi yoyenera kupanikizika kwambiri komanso kutentha kwambiri. Elastic sphere kuti mutsegule poyambira wosasunthika pansi pa malo ozungulira, ndikupeza mphamvu zotanuka. Njira yachitetezo ikazimitsidwa, mpirawo umatsegulidwa ndi mphero ya pisitoni ndodo ndipo valavu yachipata chapamwamba imamizidwa kuti isindikize. Musanayambe kutembenuza mpirawo, choyamba masulani mutu wa mphero, mpirawo ndikubwereranso ku mawonekedwe abwino, kuti mpira ndi chipika cha valve pakati pa kusiyana, chikhoza kuchepetsa ntchito yeniyeni ya makokedwe a kukangana.
Sankhani kukonzanso kwatsiku ndi tsiku kwa pinch check valve ball valve molingana ndi malo otetezeka
Vavu ya mpira molingana ndi malo ake otetezedwa atha kugawidwa molumikizana mwachindunji, njira zitatu kapena ngodya yakumanja. Ma valve awiri otsirizawa amagwiritsidwa ntchito kugawira zipangizo ndikusintha kayendedwe ka zofalitsa. Kuyika valavu ya mpira ndi kukonza kuyenera kulabadira zinthu zotsatirazi: 1. Siyani gawo lozungulira la chogwirira cha valve. 2. Sangagwiritsidwe ntchito ngati valavu yamagetsi. Ma valve a mpira okhala ndi zida zopatsirana ayenera kusonkhanitsidwa molunjika.
Kukonzekera kwatsiku ndi tsiku kwa mpira woyezera valavu
Kuyeretsa flange mpira valavu, kuti mwatsatanetsatane kuyeretsa fumbi yotsalira, madontho mafuta ndi zowonjezera zina, monga madzi ofunda sangathe kutsukidwa, sangathe kuwononga bolodi mafuta dera ndi mbali pansi pa maziko, akulimbana ndi mowa ndi wothandizila kuyeretsa. Flange mpira mavavu kuyeretsa pambuyo zotsukira kwathunthu chamunthuyo pamaso unsembe. Flange mpira valavu thupi akadali mbali yotsalira ya zinthu, komanso pansi pa ntchito zina zovuta. Pamaso kukonza valavu mpira, m`pofunika kuzimitsa valavu mpira pamaso mwadzidzidzi kudula valavu, kutsegula valavu mpira amene ayenera kukonzedwa, ndi kumasula kwathunthu flange mpira valavu mafuta dera mbale mkati dongosolo ntchito kuthamanga.
