Kusintha kwa kuthamanga kwa valve yotetezeka (kuthamanga kokhazikika):
Mu mphamvu yogwira ntchito yomwe yatchulidwa, mphamvu yotsegulira ikhoza kusinthidwa potembenuza screw yosinthira kuti musinthe compression ya spring preload. Chotsani chivundikiro cha valavu, masulani nati yotsekera, kenako sinthani screw yosinthira. Choyamba, onjezerani mphamvu yolowera kuti valavu iyambe kugwira ntchito kamodzi.
Ngati mphamvu yotsegulira ili yochepa, mangani skurufu yosinthira motsatira wotchi; ngati mphamvu yotsegulira ili yokwera, imasuleni motsatira wotchi. Mukasintha mphamvu yotsegulira, mangani nati yotsekera ndikuyika chivundikiro.
Ngati kuthamanga kofunikira kotsegulira kupitirira kuthamanga kogwira ntchito kwa kasupe, ndikofunikira kusintha kasupe wina ndi kuthamanga koyenera kogwira ntchito, kenako nkusintha. Kasupe akasinthidwa, deta yofanana ndi yomwe ili pa nameplate iyenera kusinthidwa.
Mukasintha kuthamanga kwa valavu yotetezera, mfundo zotsatirazi ziyenera kuganiziridwa:
Pamene kupanikizika kwapakati kuli pafupi ndi kupsinjika kwa kusweka (mpaka 90% ya kupsinjika kwa kusweka), sikelo yosinthira siyenera kuzunguliridwa, kuti diski isazungulire ndikuwononga pamwamba pa kutseka.
Pofuna kuonetsetsa kuti mphamvu yotsegulira ndi yolondola, mphamvu yogwiritsira ntchito mphamvu yotsegulira, monga mphamvu yapakati ndi kutentha kwapakati, iyenera kukhala pafupi kwambiri ndi mphamvu yeniyeni yogwirira ntchito. Mtundu wa mphamvu yotsegulira ukasintha, makamaka ikasintha kuchoka pa gawo lamadzimadzi kupita ku gawo la mpweya, mphamvu yotsegulira nthawi zambiri imasintha. Kutentha kogwirira ntchito kukakwera, mphamvu yosweka imachepa. Chifukwa chake, ikasinthidwa kutentha kwa chipinda ndikugwiritsidwa ntchito kutentha kwambiri, mphamvu yokhazikika ya mphamvu yotsegulira kutentha kwa chipinda iyenera kukhala yayikulu pang'ono kuposa mphamvu yotsegulira ya mpira.
Kusintha kwa kuthamanga kwa vavu yotulutsa mpweya komanso kuthamanga kwa malo okhala:
Pambuyo poti mphamvu yotsegulira yasinthidwa, ngati mphamvu yotulutsa kapena mphamvu yobwezeretsanso malo sikukwaniritsa zofunikira, mutha kugwiritsa ntchito mphete yosinthira pampando wa valavu kuti musinthe. Tsegulani screw yokonzera mphete yosinthira, ndikuyika chitsulo chopyapyala kapena chida china kuchokera pabowo la screw lomwe lawonekera, kenako mano a giya pa mphete yosinthira akhoza kusunthidwa kuti mphete yosinthira itembenukire kumanzere ndi kumanja.
Mphete yosinthira ikatembenuzidwa motsutsa wotchi kumanja, malo ake adzawonjezeka, ndipo kuthamanga kwa kutulutsa ndi kuthamanga kwa malo oimikapo zidzachepa; m'malo mwake, mphete yosinthira ikatembenuzidwa motsatira wotchi kumanzere, malo ake adzachepa, ndipo kuthamanga kwa kutulutsa ndi kuthamanga kwa malo oimikapo zidzachepa. Kuthamanga kwa mpando kudzawonjezeka. Pakusintha kulikonse, kuzungulira kwa mphete yosinthira sikuyenera kukhala kwakukulu kwambiri (nthawi zambiri mkati mwa mano 5).
Pambuyo pa kusintha kulikonse, sikulu yokonzera iyenera kumangidwa mwamphamvu kotero kuti mapeto a sikuluyi ali mu mpata pakati pa mano awiri a mphete yosinthira kuti mphete yosinthira isazungulire, koma palibe kupanikizika kwa mbali komwe kuyenera kugwiritsidwa ntchito pa mphete yosinthira. Kenako chitani mayeso a zochita. Pofuna chitetezo, musanatembenuze mphete yosinthira, kupanikizika kwa valavu yolowera kuyenera kuchepetsedwa bwino (nthawi zambiri kuchepera 90% ya kupsinjika kotsegulira), kuti valavu isatsegule mwadzidzidzi panthawi yosinthira komanso ngozi.
Dziwani kuti n'zotheka kuchita mayeso a kuthamanga kwa mpweya wotuluka m'malo mwa valavu yotetezeka komanso kuyesanso kuthamanga kwa mpweya pamene mpweya wotuluka m'malo mwa valavuyo ndi waukulu mokwanira kuti valavuyo isatseguke (ndiko kuti, pamene mphamvu yotulutsa mpweya wotuluka m'malo mwa valavu yotetezeka yafika).
Komabe, mphamvu ya benchi yoyesera yomwe nthawi zambiri imagwiritsidwa ntchito kutsimikizira kuthamanga kwa valavu yotetezera ndi yochepa kwambiri. Pakadali pano, valavuyo singathe kutsegulidwa kwathunthu, ndipo kuthamanga kwake kobwezeretsanso kumakhala kolakwika. Poyesa kuthamanga kwa kutsegula pa benchi yoyesera yotereyi, kuti kuwonekere bwino kuti kunyamuka, mphete yosinthira nthawi zambiri imasinthidwa kukhala pamalo okwera, koma izi sizoyenera malinga ndi momwe valavuyo imagwirira ntchito, ndipo malo a mphete yosinthira ayenera kusinthidwa.
chisindikizo cha lead
Ma valve onse oteteza akasinthidwa, ayenera kutsekedwa ndi lead kuti zinthu zomwe zasinthidwa zisasinthidwe mwachisawawa. Valavu yotetezera ikachoka ku fakitale, nthawi zambiri imasinthidwa ndi mpweya wabwinobwino malinga ndi malire apamwamba (monga kuthamanga kwambiri) a mulingo wa kuthamanga kwa ntchito, kupatula pazifukwa zapadera.
Chifukwa chake, ogwiritsa ntchito nthawi zambiri amafunika kusintha malinga ndi momwe zinthu zilili pantchito. Kenako sunganinso.
