Mfundo yogwira ntchito ya chizindikiro cha butterfly valve

Themoto chizindikiro butterfly valveimagwira ntchito pamapaipi a petroleum, mankhwala, chakudya, mankhwala, kupanga mapepala, hydropower, kutumiza, madzi ndi ngalande, smelting, mphamvu ndi machitidwe ena. Itha kugwiritsidwa ntchito ngati zida zowongolera komanso zopondereza pamagasi osiyanasiyana owononga komanso osawononga, amadzimadzi, ma semi fluid ndi mapaipi olimba a ufa ndi zotengera. Makamaka, amagwiritsidwa ntchito kwambiri pachitetezo cha moto cha nyumba zapamwamba ndi machitidwe ena a mapaipi omwe amafunikira kuwonetsa mawonekedwe a valve.
chikhalidwe:
1. Yaing'ono ndi yopepuka, yosavuta kusokoneza ndi kukonzanso, ndipo ikhoza kukhazikitsidwa pa malo oyika.
2. Mapangidwewo ndi osavuta komanso osakanikirana, ndipo kuzungulira kwa 90 ° kumatsegula ndikutseka mwamsanga.
3. Torque yaing'ono yogwiritsira ntchito, kupulumutsa ntchito ndi kuwala.
4. Fikirani kusindikiza kwathunthu ndi kutayikira kwa zero pakuyezetsa gasi.
5. Sankhani magawo ndi zipangizo zosiyanasiyana, zomwe zingagwiritsidwe ntchito pazinthu zosiyanasiyana.
6. Makhalidwe oyenda amakhala owongoka ndipo machitidwe amalamulo ndi abwino.
7. Chiwerengero cha mayesero otsegula ndi kutseka ndi kufika zikwi khumi, ndipo moyo wautumiki ndi wautali.
8. Paipi yogwiritsira ntchitovalve pachipata, valavu yoyang'ana (valavu yotseka), valavu yoyimitsa, valavu ya pulagi, valavu ya rabara ndi diaphragm valve ikhoza kusinthidwa ndi valve iyi, makamaka mu dongosolo la chitetezo cha moto la nyumba zapamwamba ndi dongosolo la mapaipi lomwe liyenera kusonyeza mawonekedwe a valve.
mfundo ntchito:
1. Chizindikirovalavu ya butterflyimayendetsedwa ndi giya ya nyongolotsi ndi nyongolotsi yoyendetsa mphutsi kuti izungulire tsinde ndi mbale yagulugufe kuti izindikire kutsegula ndi kutseka ndi kuwongolera kuyenda.
2. Tembenuzani gudumu la m'manja la zida za nyongolotsi ndi makina oyendetsa nyongolotsi kuti mbale ya gulugufe ikwaniritse cholinga chotsegula ndi kutseka ndi kuwongolera kuyenda. Whewelo lamanja limazungulira koloko kutseka valavu.
3. Pali mitundu iwiri ya ma microswitches omwe amaikidwa mu bokosi lotumizira mphutsi:
a. Pali ma microswitches awiri m'bokosi lotumizira, mwachitsanzo, kutseguka ndi kutseka, komwe kumagwira ntchito pamene valavu yatsegulidwa ndi kutsekedwa, ndikugwirizanitsa "valve on" ndi "valve off" zizindikiro zowunikira mu chipinda chowongolera kuti ziwonetsedwe bwino. mawonekedwe a valve.
b. Malo oyandikira a microswitch amayikidwa mu bokosi lotumizira (malo otsekedwa kwathunthu a gulugufe mbale ndi 0 °). Pamene gulugufe mbale ali pa udindo wa 0 ° ~ 40 °, ndi microswitch amachita linanena bungwe valavu kutseka chizindikiro. Pamene gulugufe mbale ali pa udindo wa 40 ° ~ 90 °, ena awiri a kawirikawiri chatsekedwa akhoza linanena bungwe valavu kutsegula chizindikiro. Kamera yomwe ikukanikiza chosinthira yaying'ono imatha kusinthidwa kuti iwonetse malo osiyanasiyana a mbale yagulugufe.
