Valavu ya pachipata cha cryogenic yokhala ndi bonnet yotalikirapo yopangidwa kuti igwire ntchito kutentha mpaka -196 ° C nthawi zambiri imamangidwa kuti ipirire kuzizira kwambiri ndikusunga magwiridwe antchito bwino m'mikhalidwe yovuta ngati imeneyi. Ma valve awa nthawi zambiri amagwiritsidwa ntchito m'mafakitale monga kukonza gasi wachilengedwe (LNG), kupanga gasi wamafuta m'mafakitale, ndi ntchito zina za cryogenic pomwe kutentha kumakhudzidwa kwambiri. kuchokera kuzizira kapena kuphulika pa kutentha kotsika koteroko. Kuonjezera apo, zipangizo zomwe zimagwiritsidwa ntchito pomanga valavu, monga ma alloys apadera kapena mapulasitiki otsika kutentha, amasankhidwa kuti akhalebe ndi mphamvu ndi kukhulupirika m'madera a cryogenic. amayesedwa mwamphamvu kuti atsimikizire kuti angathe kuthana ndi kutentha kwakukulu ndi zovuta zomwe zimakhudzidwa.
1.Mapangidwewo ndi osavuta kuposa valve yachipata, ndipo ndi yabwino kupanga ndi kusamalira.
2.Kusindikiza pamwamba sikophweka kuvala ndi kukanda, ndipo ntchito yosindikiza ndi yabwino. Palibe wachibale wotsetsereka pakati pa diski ya valve ndi kusindikiza pamwamba pa thupi la valve potsegula ndi kutseka, kotero kuvala ndi kukanda sikuli koopsa, ntchito yosindikiza ndi yabwino, ndipo moyo wautumiki ndi wautali.
3.Potsegula ndi kutseka, kugunda kwa diski kumakhala kochepa, kotero kutalika kwa valve yoyimitsa ndi yaying'ono kuposa ya valve yachipata, koma kutalika kwachipangidwe kumakhala kotalika kuposa kwa valve yachipata.
4.Kutsegula ndi kutseka torque ndi yaikulu, kutsegula ndi kutseka kumakhala kovuta, ndipo nthawi yotsegula ndi yotseka ndi yaitali.
5.Kukana kwamadzimadzi ndi kwakukulu, chifukwa njira yapakati mu thupi la valve ndi yopweteka, kukana kwamadzimadzi kumakhala kwakukulu, ndipo mphamvu yogwiritsira ntchito mphamvu ndi yaikulu.
6.Mayendedwe apakati akuyenda Pamene kuthamanga kwadzina PN ≤ 16MPa, nthawi zambiri kumatenga kuyenda kwapatsogolo, ndipo sing'anga imayenda mmwamba kuchokera pansi pa disc valve; pamene kuthamanga kwadzina PN ≥ 20MPa, nthawi zambiri kumatenga kuthamanga kwa kauntala, ndipo sing'anga imayenda pansi kuchokera pamwamba pa chimbale cha valve. Kuonjezera ntchito ya chisindikizo. Ikagwiritsidwa ntchito, sing'anga yamagetsi yapadziko lonse lapansi imatha kuyenda mbali imodzi, ndipo njira yoyendetsera siyingasinthidwe.
7.The chimbale nthawi zambiri kukokoloka pamene kwathunthu lotseguka.
Panthawi yotsegulira ndi kutseka kwa valve yachitsulo yopangidwa ndi zitsulo, chifukwa kukangana pakati pa diski ndi kusindikiza pamwamba pa thupi la valve ndi kochepa kuposa kwa valve yachipata, imakhala yosagwira ntchito.
Kutsegula kapena kutseka kwa tsinde la valve ndi kochepa kwambiri, ndipo kumakhala ndi ntchito yodalirika yodulira, ndipo chifukwa kusintha kwa doko la mpando wa valve kumakhala kofanana ndi kugunda kwa valve disc, ndikoyenera kwambiri kusintha. wa mlingo wotuluka. Choncho, valavu yamtunduwu ndi yoyenera kwambiri kudulidwa kapena kuwongolera ndi kugwedeza.

Monga katswiri wopanga ma valve opangira zitsulo komanso kutumiza kunja, tikulonjeza kupatsa makasitomala ntchito zapamwamba zotsatsa pambuyo pogulitsa, kuphatikiza izi:
1.Kupereka malangizo ogwiritsira ntchito mankhwala ndi malingaliro okonza.
2.Zolephera zomwe zimayambitsidwa ndi zovuta zamtundu wazinthu, timalonjeza kuti tipereka chithandizo chaukadaulo ndikuthana ndi mavuto munthawi yaifupi kwambiri.
3.Kupatula kuwonongeka komwe kumachitika chifukwa chogwiritsa ntchito mwachizolowezi, timapereka ntchito zokonzetsera zaulere komanso zosinthira.
4.Tikulonjeza kuti tidzayankha mwamsanga pa zosowa za makasitomala panthawi ya chitsimikizo cha mankhwala.
5. Timapereka chithandizo chaumisiri cha nthawi yayitali, kuyankhulana pa intaneti ndi ntchito zophunzitsira. Cholinga chathu ndikupatsa makasitomala chidziwitso chabwino kwambiri chautumiki ndikupangitsa zomwe makasitomala akumana nazo kukhala osangalatsa komanso osavuta.
