NKHANI ZA UTUMIKI WA NTCHITO
Pakukonzanso, ndizowona kuti valavu yamtunduwu imakhala yocheperako kuposa mtundu wina uliwonse, koma valavu ili ndi maubwino ena motere:
1. Moyo wabwino ndiwotsimikizika.
2.Pali mafuta nipple pa onse bellows chisindikizo vavu chipata pansi kupanga panopa kuonetsetsa kondomu olondola pa goli chitsamba.
Zingwe zomwe zimayambira pa tsinde mu mtundu uliwonse wa ma belu osindikizira ziyenera kukhala zoyera ngati zingatheke komanso kuthiriridwa mafuta nthawi ndi nthawi ndi mafuta otentha kwambiri.
Ndibwino kuti kusamalira zachitetezo kuyenera kuchitika osachepera miyezi itatu iliyonse.
Kukonzanso kumakhala ndi kufunikira kwakanthawi pomwe valavu imagwiritsidwa ntchito kutentha kwambiri ngati kuli kofunikira kugwiritsa ntchito mafuta amtundu wotentha kwambiri.
Pakadali pano, ndikofunikira kuti valavu imagwiritsidwa ntchito kuyambira yotseguka mpaka kutseka, komanso mosemphanitsa.
KUSANKHA VALIRE
Monga chitsogozo chazonse pakusankhidwa kwa valavu koyenera kugwiritsa ntchito, valavu yapa chipata iyenera kugwiritsidwa ntchito makamaka pa nthunzi yotsika kapena yapakatikati, mizere yotsata nthunzi, kapena ntchito zina monga kutentha kutentha. Valavu yapadziko lonse iyenera kusankhidwa kuti ipange nthunzi yapakatikati kapena kuthamanga kwambiri, komwe kudzipatula kwa zombo kumatha kukhala ndi vuto pachitetezo. Amagwiritsidwanso ntchito popanga media poyizoni kapena zachiwawa ndipo mulimonse momwe zingakhalire zovuta pamayendedwe oyenda.
Tiyenera kudziwa kuti tili ndi valavu yopangidwa mwapadera yomwe kutetezedwa kouma ndi mpweya kapena madzimadzi kumatetezedwa kwathunthu. Mu valavu, kulongedza kwazitsulo kochotsedwerako kumachotsedwa m'malo ndikutulutsa kwazitsulo kosunthika pomwe njira zonse zotayikira kudzera mu tsinde kapena thupi / bonnet zimalumikizidwa.
Ma buluu omwe amagwiritsidwa ntchito pa valavuyu adayesedwa kuti azitha kuwonongeka, zomwe zimapangitsa zotsatira zoyeserera zokwaniritsa nthawi ya moyo, kutentha, ndi kukakamizidwa kwa ASME B16.34.
