Zomwe zimafunikira pakuyika mavavu amadzi am'nyanja

Malo oyika valavu ayenera kukonzedwa pakati pa mbali imodzi ya dera la chipangizocho, ndipo malo ogwirira ntchito oyenerera kapena malo osungiramo zinthu ayenera kuperekedwa. zomwe zimafikirika mosavuta.Kutalika pakati pa valavu handwheel ndi pamwamba ntchito ndi pakati 750-1500mm, kutalika koyenera kwambiri ndi 1200mm, ndi unsembe kutalika kwa valavu sikutanthauza ntchito pafupipafupi akhoza kufika 1500-1800mm.Valavu iyenera kusungidwa patali yoyenera kuchokera pa doko la dosing kuti zisawonongeke kwambiri chifukwa cha mphamvu ya wothandizira wamba.

Valve yayikulu

Kulemera kwa thupi la valve yaikulu ndi yaikulu, mapaipi ayenera kukonzedwa mozungulira ndi kuthandizidwa mosiyana, ndipo malo ogwirira ntchito ndi kusungirako makina opatsirana ayenera kuganiziridwa, ndipo mabatani ayenera kuikidwa kumbali imodzi kapena mbali zonse za njira yopatsirana.Chophimbacho sichiyenera kuikidwa pa chitoliro chachifupi chomwe chiyenera kusokonezeka panthawi yokonza, ndipo sichiyenera kukhudza chithandizo cha payipi pamene valve imachotsedwa, ndipo chithandizocho chiyenera kukhala 50-100mm pamwamba pa nthaka.Pamene actuator ili yolemera, chithandizo china chiyenera kuperekedwa kwa icho.The unsembe njira yavalavu ya butterflyzimatsimikiziridwa molingana ndi kamangidwe ka mapaipi.Pamene payipi ndi anakonza horizontally, ndivalavu ya butterflytsinde ayenera anakonza monga horizontally ndikotheka, ndi kutsegula malangizo avalavu ya butterflyziyenera kukhala zogwirizana ndi kayendetsedwe ka kayendedwe ka sing'anga kuteteza slurry ndi zoipitsa mkatikati kuti zisalowe pa shaft ya valve ndi gawo losindikiza la thupi la valve.Vavu ikatsegulidwa, torque yogwira ntchito imakhala yaying'ono, ndipo imathandizira kutsitsa mapaipi mpaka kumlingo wina.

Thevalve yoyang'ana pansiimakonzedwa pamtunda wa mpope wa madzi a m'nyanja, ndikutsatiridwa ndi valve yotseka.Pofuna kupewa kugundana ndi kusokoneza pakati pa mbale za valve za ma valve awiri opota, gawo la chitoliro chowongoka liyenera kukhazikitsidwa pakati pa ma valve awiriwo.Kutalika kwa gawo la chitoliro chowongoka (1.5-2.0 ) DN.Ngati horizontally anakonza mphira-alimbane gulugufe mtunduvalve yoyang'ana pansiimagwiritsidwa ntchito, tsinde la valve liyenera kukhazikitsidwa molunjika, lomwe lingathe kuwonjezera moyo wautumiki wa valve.Ngati chimodzi-ku-valve check valvekapena single-disk two way steel tovalve check valveikagwiritsidwa ntchito, njira yoyika ma valve iyenera kutsata njira yotseka yokoka.
