Anthu ambiri amafuna kudziwa njira yogwirira ntchito ya valve yotsekedwa ndi zipata kuti agwiritse ntchito bwino valavuyi.Zotsatirazi ndi njira yogwirira ntchito komanso njira yochotsera zolakwika za valve yotsekedwa mofewa:
Choyamba, kutsegula ndi kutseka kwa valavu, ambiri ogwira ntchito nthawi zambiri amalakwitsa pano, ayenera kukumbukira kuti njira yotseka valve ndi yowongoka.
Chachiwiri, ngati valavu yotsekera pakhomo yofewa ikugwiritsidwa ntchito pamapaipi, chipangizo cha pneumatic mkati mwa valve chimafunika kugwira ntchito pamanja, ndipo anthu ayenera kugwiritsa ntchito njira zamanja kuti atsegule ndi kutseka.Ngati ndi valavu yayikulu, kuchuluka kwa nthawi zotsegula ndi kutseka ziyenera kusungidwa pakati pa 200 ndi 600 nthawi.
Chachitatu, mtunda wotsegulira ndi kutseka kwa mphamvu ya valve yotsekedwa yotsekedwa iyenera kusungidwa mkati mwamtundu wina, makamaka kupulumutsa anthu ogwira ntchito ndikuthandizira munthu mmodzi kuti agwire ntchito.Ngati mtunda wa mphamvu ukuposa izi, osachepera awiri kapena atatu akufunika kuti ayambe bwino valve..
Chachinayi, kukula kwa valve kumayenera kukhala kofanana.Mukayika valavu, muyenera kumvetsera valavu ya valve yachipata yomwe ikuyang'ana pansi.
Vavu yotsekera pachipatanjira yothetsera vuto:
1. Kutayikira pa kulongedza kwa valve yotsekedwa yotsekedwa
(1) Chithokomiro cholongedza ndi chotayirira kwambiri, ndipo mtedza wokanikizira chithokomiro ukhoza kumangika mofanana.
(2) Kuchuluka kwa mabwalo onyamula sikokwanira, ndipo kulongedza kuyenera kuwonjezeredwa.
(3) Kunyamula kumalephera chifukwa chogwiritsa ntchito nthawi yayitali kapena kusungidwa kosayenera.Iyenera kusinthidwa ndi kulongedza kwatsopano.Posintha, ziyenera kudziwidwa kuti zolumikizana pakati pa mphete iliyonse ziyenera kuwoloka ndikugwedezeka.
2. Pali kusiyana pakati pa mbale yachipata ya valve yotsekedwa yotsekedwa ndi malo osindikizira a mpando wa valve.
(1) Pali dothi pakati pa malo osindikizira, omwe amatha kuthetsedwa ndi kutsuka.
(2) Ngati malo osindikizira awonongeka, ayenera kukonzedwanso, ndipo ngati kuli kofunikira, akhoza kuyambiranso ndi kukonza.Malo osindikizira pansi ayenera kukhala athyathyathya, ndipo kuuma kwake sikuyenera kukhala kotsika kuposa 0,4.
3. Mtedza wotuluka pa kugwirizana pakati pa thupi la valve ndi boneti ya valavu yotseka pakhomo yofewa siimangiriridwa mwamphamvu kapena imatsekedwa mosagwirizana, ndipo ikhoza kusinthidwa.
(1) Zowonongeka (zowongoka zowongoka kapena ma groove, ndi zina zambiri) pamalo osindikizira a flange ziyenera kukonzedwa.
(2) Gasket yawonongeka ndipo iyenera kusinthidwa ndi gasket yatsopano.
4. Kutumiza kwa tsinde la valve yofewa kusindikiza sikusintha
(1) Ngati kulongedzako kuli kothina kwambiri, masulani mtedzawo bwino.
(2) Malo a chithokomiro cholongedza sicholondola, kotero kuti tsinde la valve limamatira, ndipo nati pa gland yonyamula iyenera kugwedezeka mofanana kuti ibwezeretse gland ku malo ake abwino.
(3) Ulusi womwe uli pa tsinde ndi mtedza wa tsinde wawonongeka ndipo uyenera kuchotsedwa pambuyo pa disassembly.
Ma valve otsekemera otsekemera amagwiritsidwa ntchito kwambiri.valavu yotsekera pachipata, valavu ya mafakitale, gawo lotsegula ndi lotseka la valavu yotsekera yachipata ndi chipata, kayendedwe ka chipata ndi perpendicular kwa kayendedwe ka madzi, valavu yachipata imatha kutsegulidwa ndi kutsekedwa kwathunthu, ndi sichingasinthidwe kapena kugwedezeka.Chipinda cholowera pachipata chimakhala ndi malo awiri osindikizira.Malo awiri osindikizira omwe amagwiritsidwa ntchito kwambiri pa wedge gate ma valve amapanga mawonekedwe a wedge.Mawonekedwe a mphero amasiyana ndi magawo a valve, nthawi zambiri 50, ndi 2 ° 52 pamene kutentha kwapakati sikuli kwakukulu.
Laizhou Dongsheng Valve Co., Ltd. mainly produces check valves, diaphragm valves, butterfly valves, ball valves, gate valves, etc., which are widely used in water conservancy, electric power, petroleum, chemical industry, metallurgy, gas, heating, construction, shipbuilding and other industries.
