1. Sing'anga yogwirira ntchito

Malinga ndi njira zosiyanasiyana zogwirira ntchito, ndikofunikira kusankha zinthu zokhala ndi kukana kwa dzimbiri. Mwachitsanzo, ngati sing'anga ndi madzi amchere kapena madzi a m'nyanja, aluminium bronze valve disc ikhoza kusankhidwa; Ngati sing'anga ndi asidi amphamvu kapena alkali, tetrafluoroethylene kapena fluororubber wapadera akhoza kusankhidwa monga chuma mpando valavu.

2.Kuthamanga kwa ntchito ndi kutentha

valavu ya butterfly yosindikiza mphirakufunikira kogwira ntchito moyenera mkati mwa kukakamizidwa kogwira ntchito komanso kutentha, kotero ndikofunikira kusankha zida zokhala ndi mphamvu zokwanira komanso kukana kutentha.

3. Mikhalidwe ya chilengedwe

Ganizirani za chilengedwe chomwe valavu ili, monga chinyezi, kutsitsi mchere, ndi zina zotero, ndikusankha zinthu zoyenera. 

4.Valve thupi zakuthupi

The vavu thupi zipangizo zavalavu ya butterfly ya flangezikuphatikizapo imvi kuponyedwa chitsulo, ductile chitsulo, zitsulo zosapanga dzimbiri, zitsulo zosapanga dzimbiri, etc. Pakati pawo, zitsulo zosapanga dzimbiri zimakhala ndi ntchito yabwino, koma mtengo wake ndi wokwera kwambiri. Ngati ili pamalo otsika kwambiri, ntchito ya chitsulo cha ductile ikhoza kufananizidwa ndi chitsulo choponyedwa, ndipo mtengo wogwiritsira ntchito chitsulo cha ductile ndi wotsika.

5.Valve mpando chuma

Zida zokhalamo zavalavu ya butterfly ya worm gearzikuphatikizapo mphira ndi fluoroplastics. Mipando ya valavu ya mphira ingagwiritsidwe ntchito muzofalitsa zofooka za acidic ndi zamchere monga madzi, nthunzi, ndi mafuta, ndi ntchito yabwino yosindikiza; Mipando ya valavu ya fluoroplastic imagwiritsidwa ntchito pazofalitsa zowononga kwambiri.

6. Gulugufe chimbale zakuthupi

Zida za gulugufe za mavavu agulugufe zamanja zimaphatikizansopo chitsulo cha ductile ndi chitsulo chosapanga dzimbiri. Nthawi zina, kuti azolowere zovuta TV mapangidwe, m'pofunika kukulunga gulugufe chimbale ndi guluu kapena PTFE zakuthupi.

7.Valve shaft zakuthupi

Ambiri aiwo amapangidwa ndi zitsulo zosapanga dzimbiri, ndipo mikhalidwe yapadera imatha kusinthidwa malinga ndi zosowa.

8.Drive zakuthupi

Pali njira ziwiri zazikuluzikulu zogwirira ntchito pamanja, chogwirira ndi zida za nyongolotsi. Zida zogwirira ntchito zimaphatikizapo chitsulo choponyedwa, chitsulo cha carbon, chitsulo chosapanga dzimbiri, zitsulo zotayidwa, ndi zina zotero; Zida za mutu wa giya ya nyongolotsi nthawi zambiri zimakhala chitsulo choponyedwa.

Mwachidule, kusankha zinthu khalidwe lavalavu ya butterfly yamanjaayenera kuganizira mozama zinthu monga sing'anga yogwirira ntchito, kuthamanga kwa ntchito ndi kutentha, momwe chilengedwe chimakhalira, komanso zida za valavu, mpando wa valve, chimbale cha butterfly, ndi shaft ya valve. The olondola zinthu kusankha angatsimikizire yachibadwa ntchito ndi moyo utumiki wavalavu ya butterfly.
