ZF8006 Stainless Steel wamkazi ulusi swing check valve DN20

imalepheretsa sing'anga yomwe ili mupaipi kuti isabwererenso.Valavu yomwe mbali zake zotsegula ndi zotsekera zimatsegulidwa kapena kutsekedwa ndi kuyenda ndi mphamvu yapakati kuti ateteze sing'anga kubwerera kumbuyo imatchedwa cheke.Ma valve owunikira ali m'gulu la ma valve odziyimira pawokha, omwe amagwiritsidwa ntchito makamaka m'mapaipi pomwe sing'anga imayenda mbali imodzi, ndipo amangolola sing'anga kuyenda mbali imodzi kuti apewe ngozi.Vavu yamtunduwu iyenera kuyikidwa mopingasa mu payipi.Valavu yoyang'ana swing imatengera mawonekedwe a rocker omangidwa mkati.Zigawo zonse zotsegula ndi zotseka za valve zimayikidwa mkati mwa thupi la valve ndipo musalowe mu thupi la valve.Kupatulapo gasket yosindikiza ndi mphete yosindikizira pakati pa flange, yonse Palibe malo othawirako, kuteteza kuthekera kwa kuvunda kwa valve.Kulumikizana pakati pa mkono wogwedezeka wa valavu ya swing check valve ndi valve clack kumatenga njira yolumikizira yozungulira, kotero kuti clack ya valve imakhala ndi ufulu wochuluka mkati mwa madigiri a 360, ndipo pali malipiro oyenerera.Ma valve a swing cheque akhala akugwiritsidwa ntchito kwambiri m'magawo ambiri monga makampani opanga mankhwala, zitsulo, ndi mankhwala.

Kapangidwe ndi mawonekedwe a valavu ya cheki:

1. Kusankhidwa kopambana kwa zida zama valavu zoyendera, mogwirizana ndi zofunikira zapakhomo ndi zakunja, komanso zida zapamwamba kwambiri.

2. Kusindikiza kusindikiza kwa valve yoyang'ana ndipamwamba komanso koyenera.Malo osindikizira a valve clack ndi mpando wa valve amapangidwa ndi alloy-based alloy kapena stellite cobalt-based cemented cemented carbide pamwamba, yomwe imakhala ndi kukana, kukana kutentha, kukana kwa dzimbiri komanso kukana kukanika.Moyo wabwino komanso wautali wautumiki.

3. Valve yowunikira imapangidwa ndikupangidwa molingana ndi muyezo wadziko lonse wa GB/T12235.

4. Valavu yoyang'ana imatha kutengera miyezo yosiyanasiyana ya piping flange ndi mitundu yosindikiza ya flange kuti ikwaniritse zosowa zosiyanasiyana zamainjiniya ndi zofunikira za ogwiritsa ntchito.

5. Zida za thupi la valve za valve yowunikira zatha, ndipo gasket ikhoza kusankhidwa moyenerera malinga ndi momwe ntchito yeniyeniyo ikugwirira ntchito kapena zofunikira za wogwiritsa ntchito, ndipo ikhoza kukhala yoyenera kupanikizika kosiyanasiyana, kutentha ndi ntchito zapakati.Malinga ndi zofunikira za ogwiritsa ntchito, ma valavu owunika omwe ali ndi mawonekedwe osiyanasiyana ndi maulumikizidwe amatha kupangidwa ndikupangidwa kuti agwiritsidwe ntchito ndi zida zosiyanasiyana.

Vavu yowunikira imatanthawuza valavu yomwe imatsegula ndi kutseka diski malinga ndi kutuluka kwa sing'anga yokha, ndipo imagwiritsidwa ntchito kuteteza sing'anga kuti isabwererenso.Imatchedwanso valavu yoyendera, valavu ya njira imodzi, valavu yothamanga, ndi valve yothamanga kumbuyo.Valve yowunikira ndi mtundu wa valve yokhayokha, ntchito yake yayikulu ndikuletsa kutuluka kwapakati kwapakati, kuletsa mpope ndi kuyendetsa galimoto kuti zisabwerere, komanso kutulutsa sing'anga ya chidebe.Ma valve owunika amathanso kugwiritsidwa ntchito popereka mapaipi a machitidwe othandizira pomwe kupanikizika kumatha kukwera pamwamba pa kukakamiza kwa dongosolo.Chongani mavavu akhoza makamaka kugawidwa mu swing cheke mavavu ndi kukweza cheke mavavu.Valavu yowunikira ndi yoyenera kwa mapaipi azinthu zosiyanasiyana zogwirira ntchito mumafuta amafuta, mankhwala, mankhwala, feteleza, ndi mphamvu zamagetsi zokhala ndi mphamvu ya PN1.6 ~ 16.0MPa ndi kutentha kwa ntchito -29 ~ + 550 °.Sing'anga yoyenera ndi madzi, mafuta, nthunzi, Acidic medium, etc.

Vavu yowunikira imatsegulidwa yokha ndikutsekedwa ndi mphamvu yomwe imapangidwa ndikuyenda kwa sing'anga yokha mu payipi, ndipo ndi ya valavu yokhayokha.Valve yowunikira imagwiritsidwa ntchito pamapaipi, ndipo ntchito yake yayikulu ndikuletsa sing'anga kuti isabwerere mmbuyo, kuteteza mpope ndi galimoto yake yoyendetsa galimoto kuti isabwerere, ndikutulutsa sing'anga mu chidebecho.Valve yowunikira ingagwiritsidwenso ntchito kupereka mapaipi komwe kupanikizika kwa dongosolo lothandizira likhoza kukwera pamwamba pa kupanikizika kwa dongosolo lalikulu.Ntchito ya valavu ya cheki ndikuletsa sing'anga mu payipi kuti isabwererenso.Ma valve owunika ali m'gulu la ma valve odzichitira okha, omwe amatsegula kapena kutseka basi ndi mphamvu ya sing'anga yoyenda.Chovala chotchinga chimangogwiritsidwa ntchito papaipi pomwe sing'anga imayenda mbali imodzi kuteteza sing'angayo kuti isabwererenso kuteteza ngozi.Sing'anga yoyenera ya valve cheke ndi madzi, mafuta, nthunzi, sing'anga ya asidi, etc.
