Pamalo osungira madzi ku Laos, kasitomala adagula yekha ma valve a gulugufe ndi malo olumikizira raba kuti agwirizane ndi mapaipi, ndipo zida zinawonongeka pambuyo pomanga. Kasitomala adagula ma valve a gulugufe a DN300 ndi malo olumikizira DN300 padera, ndikuyika maoda molingana ndi kukula kwake. Popanda kufunsa akatswiri aukadaulo kuti atsimikizire kukula kwa zinthuzo, kasitomala adanyalanyaza kusiyana kwa mkati mwa mitundu iwiriyi ya zinthu.

Pambuyo poyika ndi kuyiyika, zidapezeka kuti m'mimba mwake weniweni wa cholumikizira cha DN300 ichi ndi chocheperako kuposa njira yamkati ya valavu ya gulugufe yokhala ndi kukula kofanana. Pamene cholumikizira cha valavu ya gulugufe chizungulira, chimatsekedwa ndi doko la cholumikizira cha expansion. Cholumikizira cha valavu sichingatseguke mokwanira, kotero dongosolo la mapaipi silingagwire ntchito mwachizolowezi.

Jinbin Valve inapereka dongosolo lokonzanso lotsatira: chotsani valavu yoyambirira ya gulugufe ndikuyiyikanso valavu ya gulugufe ya flange yogwirizana ndi cholumikizira ichi chokulitsa. Malinga ndi kutalika kwa kapangidwe ka valavu yatsopano ya gulugufe, dulani ndikusintha payipi yomwe ili pamalopo kuti ikonzedwenso, kenako malizitsani ntchito yolimbitsa flange pakati pa cholumikizira chokulitsa ndi valavu yatsopano. Njira yonse yokonzanso imaphatikizapo kudula payipi, kuchotsa zigawo zakale, kuyimika valavu yatsopano, kuyang'anira pakati pa flange ndi kutseka. Njirayi imatenga nthawi yambiri komanso imafuna ntchito yambiri, zomwe zimapangitsa kuti pakhale ndalama zowonjezera pantchito, zipangizo ndi nthawi yomanga, komanso kuchedwetsa kupita patsogolo kwa polojekitiyi.

Nkhaniyi ikupereka chikumbutso chofunikira pa kugula mainjiniya akunja. Posankha ma valve a mapaipi ndi malo olumikizirana owonjezera, ogula sayenera kusankha ndikugula zinthu malinga ndi kukula kwa DN kokha. Ma valve amitundu yosiyanasiyana (ma valve a gulugufe, ma valve a gulugufe ozungulira) ndi malo olumikizirana owonjezera amasiyana malinga ndi chibowo chamkati, kapangidwe ka nkhope yomaliza ndi kutalika kwa malo oikira ngakhale atakhala ndi mainchesi ofanana.

Pa kugula mainjiniya akunja, eni ake a polojekiti ayenera kupereka magawo a momwe ntchito ikuyendera kuphatikizapo kufotokozera mapaipi, mphamvu yapakati, mphamvu yogwirira ntchito ndi malo oikira kwa mainjiniya aukadaulo opanga ma valve pasadakhale. Akatswiri aukadaulo ayenera kumaliza kusankha ndi kufananiza mitundu yogwirizana. Musagule ma valve ndi zida za mapaipi padera ndikuzisonkhanitsa mwachisawawa pamalopo. Kugula ndi kusonkhanitsa zinthu mopanda chidwi kungayambitse kusokoneza kwa mabowo, kulephera kutseka, kutseka ma disc a ma valve ndi zolakwika zina, zomwe zimapangitsa kuti ntchito ikonzedwenso komanso kuwononga nthawi ndi ndalama za polojekiti. Kulankhulana kwaukadaulo kwaukadaulo musanayambe ntchito ndiye chinsinsi chotsimikizira kukhazikitsidwa kokhazikika komanso kuyambika bwino kwa dongosolo lanu la mapaipi.

Monga wopanga ma valve wokhala ndi zaka 22 zakuchitikira, Jinbin Valve imapanga ma valve osiyanasiyana achitsulo ndi ma valve aukadaulo osamalira madzi. Tili ndi gulu la akatswiri aukadaulo, timasintha ma valve malinga ndi momwe malo ogwirira ntchito amagwirira ntchito ndikupereka mayankho abwino kwambiri kwa makasitomala apadziko lonse lapansi. Ngati muli ndi zofunikira zilizonse, chonde titumizireni uthenga pansipa. Mudzalandira yankho mkati mwa maola 24. Tikuyembekezera kugwira nanu ntchito.
