Momwe mungayikitsire Ball Valve

Kukonzekera musanayike:

1. Onetsetsani kuti payipi pa unsembe udindo wavalavu ya mpiraili m'malo a coaxial, ndipo ma flange awiri omwe ali paipiyo ayenera kukhala ofanana kuti atsimikizire kuti payipiyo imatha kunyamula kulemera kwa valve yokhayo ya mpira.Zikapezeka kuti payipi silingathe kupirira kulemera kwa valavu ya mpira, perekani chithandizo chofananira cha payipi musanayike.

2. Kutsimikizira ngati pali zonyansa, kuwotcherera slag, etc. mu payipi, payipi iyenera kutsukidwa.

3. Chongani nameplate yavalavu ya mpira, ndikuchita ntchito zotsegula ndi kutseka kwathunthu pa valavu ya mpira kangapo kuti mutsimikizire kuti valavu imatha kugwira ntchito bwino, ndiyeno fufuzani mozama tsatanetsatane wa valve kuti muwonetsetse kuti valavu ilibe.

4. Chotsani chivundikiro chotetezera pamapeto onse a valve, yang'anani ngati thupi la valve ndi loyera, ndipo yeretsani valavu ya thupi.Popeza malo osindikizira a valve ya mpira ndi ozungulira, ngakhale zinyalala zazing'ono zimatha kuwononga malo osindikizira.

Ndemanga pa kukhazikitsa:

1. Chigawo chilichonse cha valavu ya mpira chikhoza kukhazikitsidwa kumapeto kwa mtsinje, ndipo valavu ya mpira ikhoza kuikidwa pamalo aliwonse mu payipi.Ngati valavu ya mpira yokhala ndi actuator (monga bokosi la gear, magetsi-pneumatic actuator) yakhazikitsidwa, iyenera kukhazikitsidwa molunjika, polowera ndi kutuluka kwa valve.pamalo opingasa.

2. Gasket imayikidwa pakati pa valavu ya mpira ndi flange ya payipi malinga ndi zofunikira za mapangidwe a mapaipi.

3. Mabotolo pa flange ayenera kumangirizidwa mofanana, motsatizana komanso mofanana.

4. Ngativalavu ya mpirantchito ndi pneumatic, magetsi ndi actuators ena, malizitsani kukhazikitsa mpweya gwero ndi magetsi malinga ndi malangizo.
