Posachedwapa, gulu la anthu opanda mutumavavu a gulugufe okulungiraMa valve a gulugufe a rabara opangidwa kuchokera ku fakitale yathu akonzedwa bwino, okhala ndi kukula kwa DN80 ndi DN150, ndipo posachedwa atumizidwa ku Malaysia. Gulu la ma valve a gulugufe a rabara, monga mtundu watsopano wa yankho lowongolera madzi, lawonetsa zabwino zambiri m'mafakitale ambiri chifukwa cha kapangidwe kake kapadera komanso zinthu zake.

Choyamba, poyerekeza ndi zachikhalidwemavavu a gulugufe opindikaMa valve a gulugufe a rabara amagwiritsa ntchito rabara yolimba kwambiri ngati chinthu chomangira, zomwe sizimangowonjezera magwiridwe antchito a valavu, komanso zimakulitsa moyo wa ntchito ya chinthucho. M'malo ovuta ogwirira ntchito monga kutentha kwambiri, kuthamanga kwambiri, kapena zinthu zowononga, ma valve a gulugufe a rabara amathabe kukhala ndi malo abwino ogwirira ntchito, kuchepetsa ndalama zokonzera komanso nthawi yopuma.

Kachiwiri, kapangidwe ka valavu ya gulugufe ya rabara ya Dn200 ndi kosavuta komanso kogwira mtima. Njira yake yokhazikitsira valavu imalola kuti valavu iyikidwe mwachangu ndikusinthidwa popanda kusokoneza payipi, zomwe zimapangitsa kuti ntchito igwire bwino ntchito. Kapangidwe kameneka kamatanthauzanso kuti valavuyi imatenga malo ochepa, zomwe mosakayikira ndi zabwino kwambiri m'malo omwe ali ndi malo ochepa.

Ma valve a gulugufe amtengo wapatali a mphira ndi oyenera kunyamula zakumwa ndi mpweya (kuphatikizapo nthunzi) ndi zinthu zina m'mapaipi osiyanasiyana a mafakitale. Angagwiritsidwe ntchito m'zinthu zamadzimadzi zomwe sizikuwonongeka bwino ndipo amagwiritsidwa ntchito powongolera malo awiri a switch kapena kusintha kayendedwe ka madzi. Amagwiritsidwa ntchito kwambiri pazakudya, mankhwala, mankhwala, mafuta, magetsi, nsalu, mapepala ndi malo ena. Kutentha kwake kogwira ntchito nthawi zambiri sikupitirira 180 ℃, ndipo kuthamanga kwake ndi ≤ 1.6MPa.

Kuphatikiza apo, valavu ya gulugufe ya chogwirira cha rabara ndi yosavuta kugwiritsa ntchito, ndipo kutsegula ndi kutseka mwachangu kumachitika pozungulira tsinde la valavu, liwiro loyankha mwachangu, komanso kulondola kwambiri, zomwe zimapangitsa kuti ikhale yoyenera kwambiri pazochitika zomwe kusintha kwa kayendedwe ka madzi pafupipafupi kumafunika. Kuphatikiza apo, chifukwa cha kulemera kwake kopepuka komanso kakang'ono, mayendedwe ndi kukhazikitsa ndizosavuta kwambiri, zomwe zimapulumutsa ndalama zofunika zoyendetsera zinthu ndi antchito kwa mabizinesi.
