Kodi pali zofunikira zilizonse poyika njira ya mavavu agulugufe?

Mayendedwe unsembe wavalavu ya butterflys ayenera kutsimikiziridwa molingana ndi mtundu wawo ndi momwe amagwirira ntchito. Mavavu agulugufe otsekedwa ndi Bidirectional nthawi zambiri sakhala ndi mayendedwe okhwima, koma pali mayendedwe omwe akulimbikitsidwa kukhazikitsa; Valavu yagulugufe yosindikizidwa ikuyenera kuyikidwa momwe muvi wasonyezera, ndipo komwe tsinde la valavu liyenera kupeŵa kutsika pansi kuti zitsimikizire kugwira ntchito motetezeka ndi kusindikiza.

Mavavu agulugufe amagawidwa m'mitundu iwiri: kusindikiza kwapawiri komanso kusindikiza unidirectional. Kwa bidirectional losindikizidwavalavu butterfly, mwakuti palibe zoletsa zokhazikika pakuyika, koma pali njira zolimbikitsira pakuyika muukadaulo wothandiza. Mwachitsanzo, mu payipi yopingasa, mayendedwe a tsinde la valavu amatha kusankhidwa motsatira njira yolunjika mmwamba, yopingasa, ndi 45 ° m'mwamba. Njira yoyikayi ndiyosavuta kugwiritsa ntchito ndipo imatha kutsimikizira kufanana kwa chisindikizocho. Kwa mavavu agulugufe okhala ndi m'mimba mwake (monga DN500 ndi pamwambapa), tikulimbikitsidwa kuti muyike thupi la valavu molunjika ndi choyatsira pamwamba kuti mupewe kulemera kwa mbale ya valve pa torque. Ngati cholumikizira cha mapaipi chili ndi matope (monga matope, mchenga, ndi madzi), ndibwino kuti madziwo alowe kuchokera kuseri kwa valavu yotsekera kuti achepetse kutha ndi kukulitsa moyo wa mavavu.

Unsembe wa njira imodzi losindikizidwavalavu butterflyali ndi zofunikira zomveka bwino. Thupi la valavu nthawi zambiri limakhala ndi mivi, ndipo komwe muvi wolowera kuyenera kukhala kogwirizana ndi komwe kumayendera sing'anga mupaipi panthawi yoyika, apo ayi zitha kuyambitsa kulephera kwa chisindikizo kapena kutayikira kwapakati.

Mavavu agulugufe amitundu iwiri ndi omwe saloledwa kuyikika molunjika kunsi kwa tsinde la valavu. Ngati tsinde la valavu layang'ana pansi, sing'anga ya mapaipi imatha kutsika kuchokera ku tsinde la valavu, makamaka potumiza zinthu za acidic, alkaline, ndi zapoizoni, zomwe zitha kuwopseza chitetezo chaogwiritsa ntchito. Kuonjezera apo, kuyika tsinde la valve pansi kudzawonjezera zovuta zogwirira ntchito, zomwe zimafuna kuti wogwiritsa ntchito azikweza mutu wawo kuti agwire ntchito, zomwe sizikugwirizana ndi mapangidwe a ergonomic.

Kuyika kwa mavavu agulugufe kuyenera kukhala kosavuta kugwira ntchito. Chogwirizira kapena gudumu lamanja la ma valve agulugufe nthawi zambiri amakhala 1.2 mita kuchokera pansi, pafupi ndi pachifuwa, zomwe zimapangitsa kutsegula ndi kutseka kukhala kosavuta. Ngati valavu yayikidwa pansi, chogwirira kapena chogwirira chiyenera kuyang'ana mmwamba osati kupendekera; Ngati atayikidwa motchinga makoma kapena zida, siyani malo oyimirira kwa ogwira ntchito kuti asagwire ntchito kuchokera kumwamba.
