Chiyambi cha valavu ya mpira wa cryogenic

Mfundo yogwira ntchito

Valavu yotsika kwambiri ya mpira imagwiritsidwa ntchito ngati kutentha kwapakati kuli pansipa -40 ℃, ndipo chotchinga cha valve chimatsegulidwa ndi kutsekedwa malinga ndi kutuluka kwa sing'anga yokha, kuti ateteze sing'angayo kuti isabwererenso.

Mawonekedwe

1. Mapangidwe otsegulira dzenje lothandizira pazitsulo za valve amatengedwa;
2. Gasket imapangidwa ndi zinthu za ceramic zodzaza ndi kusindikiza kokhazikika;
3. Thupi la valve ndi lopepuka komanso laling'ono.Pofuna kuchepetsa kutentha kwa thupi la valve, makamaka kuonetsetsa kuti valavu ikugwiritsidwa ntchito pansi pa kutentha kwapamwamba kwambiri, thupi la valve limapangidwa mwapadera kuti likhale lopepuka komanso lochepa;
4. Valavu yakutali imakhala ndi valavu yomwe madzi otsika kutentha amayenda.Imatengera mawonekedwe a tsinde lalitali la valve, lomwe lingapewe zotsatira za kutentha kwakunja ndikusunga chithokomiro pa kutentha kwabwino kuti zisawonongeke kuti chisindikizo cha chivundikiro chisachepetse.Utaliwu ndi utali wokwanira wopezedwa powerengera ndi kuyesa.

Ubwino wogwiritsa ntchito

1. Kukana kwamadzimadzi kumakhala kochepa.Valavu ya mpira imakhala ndi kukana kwamadzi pang'ono pakati pa ma valve onse.Ngakhale valavu yocheperako ya mpira imakhala ndi kukana kwamadzi pang'ono;
2. Kusintha kwachangu komanso kosavuta.Malingana ngati tsinde la valve likuzungulira 90 °, valve ya mpira imamaliza kutsegulira kwathunthu kapena kutseka kwathunthu, ndipo n'zosavuta kuzindikira kutsegula ndi kutseka mofulumira;
3. Kuchita bwino kosindikiza.Mphete yosindikiza ya mpando wa valve ya mpira nthawi zambiri imapangidwa ndi zinthu zotanuka monga polytetrafluoroethylene, zomwe zimakhala zosavuta kutsimikizira kusindikiza, ndipo mphamvu yosindikizira ya valve ya mpira imawonjezeka ndi kuwonjezeka kwapakati papakati;
4. Chisindikizo cha tsinde ndi chodalirika.Pamene valavu ya mpira imatsegulidwa ndi kutsekedwa, tsinde la valve limangozungulira, kotero kuti chisindikizo cha tsinde la valve sichiri chosavuta kuonongeka, ndipo mphamvu yosindikiza ya chisindikizo chotsalira cha tsinde la valve imawonjezeka ndi kuwonjezeka kwapakati papakati. ;
5. Kutsegula ndi kutseka kwa valve ya mpira kumangozungulira 90 °, kotero n'zosavuta kuzindikira kuwongolera ndi kuwongolera kutali.Valavu ya mpira imatha kukhala ndi zida za pneumatic, zida zamagetsi, zida zamagetsi zamagetsi, zida zolumikizirana ndi gasi-zamadzimadzi kapena zida zolumikizirana ndi electro-hydraulic;
6. Njira ya valve ndi yosalala komanso yosalala, ndipo sikophweka kuyika sing'angayo, ndipo payipi imatha kudutsa mu mpirawo.

Kusamalira

1. Yang'anani ngati pali ayezi mu thupi la valve, ngati ndi choncho, chonde chotsani ayezi mu thupi la valve, ndiyeno mugwiritseni ntchito valve;
2. Gwiritsani ntchito mfuti yamoto kapena ya pneumatic kuti mudzaze njira yoyeretsera valavu, ndipo gwiritsani ntchito valve pambuyo pa mphindi 10-20 kuti mutulutse zimbudzi mumphuno yotulutsa valve;
3. Yang'anani kulongedza kwa tsinde la valve, flange yapakatikati ndi mbali zina za kutayikira;
4. Ngati pali kutayikira mu tsinde la valavu, chonde onani ngati valavu ili ndi mawonekedwe a jekeseni wa valavu, ngati ndi choncho, lowetsani pang'onopang'ono mafuta osindikizira a valve ndikusiya kudzaza;
5. Chithandizo chamkati chamkati cha valve yotsika kutentha kwa mpira chatsukidwa, ndipo yankho lalikulu ndi ntchito.Kuwonjezera mafuta osindikiza ndi njira yothandizira;
6. Pamene valavu yatsekedwa kwathunthu, kuyang'anitsitsa kutuluka kwamkati ndi chithandizo cha valve yotsika kutentha kwa mpira kuyenera kuchitidwa momwe mungathere;
Ntchito ya valve yozizira iyenera kutsegulidwa ndi kutseka kwathunthu momwe zingathere, ndipo valavu yomwe singatsegulidwe ndi kutsekedwa iyenera kusuntha momwe mungathere.
