Mpira Woyandama Vavu
valavu ya mpira yoyandama ndi chiyani?
A Mpira Woyandama Vavuimagwiritsa ntchito mpira wozungulira ndi tsinde lomwe limapereka mphamvu zoyatsa/kuzimitsa.
Thevalavu ya mpira yoyandamagwiritsani ntchito kuthamanga kwa mzere wachilengedwe kukanikiza ndikusindikiza mpirawo pampando wakumunsi.Kuthamanga kwa mzere kumawonekera pamtunda waukulu - nkhope yonse ya kumtunda kwa mpira, yomwe ndi malo ofanana ndi kukula kwake kwa chitoliro.
A valavu ya mpira woyandamandi valavu yokhala ndi mpira wake woyandama (wosakhazikika ndi trunnion) mkati mwa thupi la valve, imalowera kumunsi kwa mtsinje ndikukankhira mwamphamvu mpando pansi pa mphamvu yapakatikati kuti iwonetsetse kudalirika kwa kusindikiza.Valve yoyandama ya mpira imakhala ndi mawonekedwe osavuta, ntchito yabwino yosindikizira koma zida zapampando zimafunikira kupirira ntchitoyo popeza kukakamiza kosindikiza kumatsekedwa ndi mphete yapampando.Chifukwa cha kusapezeka kwa zida zogwirira ntchito zapamwamba, valavu ya mpira woyandama imagwiritsidwa ntchito makamaka pakati kapena kutsika kwapakati.
Vavu ikayikidwa pomwe chibowocho chimalumikizidwa mbali imodzi ndi payipi, imakhala pamalo otseguka, ndipo madzimadzi amatha kudutsa pansi.Malingaliro a kampani NORTECHVavu ya mpira woyandama ndi chinthu chatsopano chopangidwa ndikusintha valavu wamba ndikutengera mulingo waposachedwa wapadziko lonse lapansi.
Zofunikira zazikulu za valavu ya mpira yoyandama ya NORTECH?
1. Kupanga Mpando Wapadera
timatengera mapangidwe a mphete yosindikizira yosinthika ya valve yoyandama ya mpira.Kuthamanga kwapakati kukakhala kochepa, malo okhudzana ndi mphete yosindikizira ndi mpira amakhala ochepa.Idzachepetsa mikangano ndi torque yogwiritsira ntchito ndikuwonetsetsa kulimba munthawi yomweyo.Pamene kuthamanga kwapakati kukuchulukira, malo olumikizana ndi mphete yosindikizira ndi mpira amakhala wamkulu komanso kupindika kwa mphete yosindikizira, kotero mphete yosindikizira imatha kupirira sing'anga yapamwamba. kukhudza popanda kuonongeka.

2. Kapangidwe Kapangidwe ka Moto
Pakayaka moto mukamagwiritsa ntchito valavu, mphete yapampando yopangidwa ndi PTFE Kapena zinthu zina zosakhala zitsulo zimawonongeka kapena kuonongeka ndi kutentha kwakukulu ndipo zimabweretsa kutayikira kwakukulu kwamadzimadzi, ndizowopsa kwa sing'anga yoyaka kapena yophulika. Mphete yosindikizira yotchinga moto imayikidwa pakati pa mpira ndi mpando kotero kuti mpando wa valve ukawotchedwa, sing'angayo imakankhira mpirawo mwachangu kupita ku mphete yosindikizira yachitsulo kuti ipange chitsulo chothandizira kupanga chitsulo chosindikizira chomwe chimatha kuwongolera bwino kutayikira kwa valve. Komanso, pakati flange kusindikiza gasket, amene angathe kutsimikizira kusindikiza ngakhale kutentha kwambiri.

3. Anti-static Structure
Valve ya mpira idapangidwa ndi anti-static structure ndi static power discharge chipangizo kuti ipange mwachindunji njira yokhazikika pakati pa mpira ndi thupi kudzera pa tsinde kuti itulutse magetsi osasunthika omwe amapangidwa chifukwa chakugunda kwa mpira ndi mpando, kupewa moto kapena kuphulika. zomwe zingayambitsidwe ndi static sparkle ndikuwonetsetsa chitetezo chadongosolo.
Anti-Static kapangidwe kamangidwe ka valavu mpira ndi DN32 ndi pamwamba
Kapangidwe ka Anti-Static kavavu kakang'ono kuposa DN32
4. Kusindikiza kodalirika kwa tsinde la valve
Tsinde limapangidwa ndi phewa pansi pake kotero kuti silidzawomberedwa ndi sing'anga ngakhale pansi pavuto lalikulu monga kukwera kwachilendo mkati mwa valve, kulephera kwa mbale ya gland ndi etc. Kuphatikiza apo, kupewa kutayikira pambuyo pake. kulongedza tsinde kutenthedwa ngati moto, kukakamiza kumayikidwa pamalo pomwe phewa ndi kukhudzana kwa thupi kuti apange mpando wosindikizira mobwerera.Mphamvu yosindikiza ya chisindikizo cham'mbuyo idzawonjezeka malinga ndi kuchuluka kwa kuthamanga kwapakati, kuti zitsimikizire kusindikizidwa kwa tsinde pansi pa zovuta zosiyanasiyana, kupewa kutayikira ndikupewa kufalikira kwa ngozi. kulongedza kungathe kusintha mphamvu yokakamiza ndi mphamvu yapakatikati ya gland kukhala mphamvu yosindikiza ya tsinde.Malinga ndi zomwe ogwiritsa ntchito amafuna, makina osindikizira a disc atha kutengedwa kuti apangitse kusindikiza kwa tsinde kukhala kodalirika.
pansi wokwera tsinde sadzawomberedwa kunja pansi sing'anga kuthamanga
tsinde lokwera pamwamba likhoza kuphulika pansi pa kupanikizika kwapakatikati

makina onyamula katundu wa Spring
5. Kuteteza Kutsekera ndi Kusokoneza
Valve yamanja ya mpira imatha kutsekedwa ndi loko pa Open Open kapena kutseka kwathunthu.Chidutswa cha 90 ° chotseguka ndi chotseka chokhala ndi dzenje lotsekera chapangidwa kuti chipewe kusokoneza ma valve chifukwa cha opreators osaloledwa, komanso kutha kuteteza kutseguka kapena kutseka kwa valve, kapena ngozi zina zomwe zimachitika chifukwa cha kugwedezeka kwa mapaipi kapena zinthu zosayembekezereka.Ndiwothandiza kwambiri makamaka pamafuta oyaka komanso kuphulika, mapaipi opangira mankhwala ndi zamankhwala kapena machubu akumunda.Mbali pamutu wa tsinde kuti anaika ndi chogwirira utengera lathyathyathya kapangidwe.Kumene valavu imatsegulidwa, chogwiriracho chimakhala chofanana ndi payipi, ndipo zizindikiro zotseka za valve zimatsimikiziridwa kuti ndizolondola.
