BS 1868 ndi Muyezo waku Britain womwe umatchula zofunikira pazitsulo zoyang'anira zitsulo kapena mavavu osabwerera okhala ndi mipando yachitsulo kuti agwiritsidwe ntchito m'mafakitale monga mafuta, petrochemical, ndi mafakitale ogwirizana. Muyezo uwu umakhudza miyeso, kutentha-kutentha, zipangizo, ndi zofunikira zoyezetsa ma valve oyendetsa. muyezo. Izi zimatsimikizira kuti valavu imatha kuteteza bwino kubwereranso ndikukwaniritsa zofunikira za chitetezo ndi khalidwe labwino pa ntchito yomwe ikufunidwa.Zina mwazinthu zazikulu za valavu ya swing check valve yopangidwa ku miyezo ya BS 1868 ingaphatikizepo chivundikiro chotsekedwa, mphete zowonjezeredwa, ndi kugwedezeka. - mtundu wa disc. Ma valve awa nthawi zambiri amagwiritsidwa ntchito pazitsulo zothamanga kwambiri komanso kutentha kwambiri kumene kuteteza kubwerera n'kofunika.Ngati muli ndi mafunso enieni okhudza swing check valve yopangidwa ku BS 1868 miyezo kapena mukufuna tsatanetsatane wazomwe zimapangidwira, zipangizo, kapena zofunikira zoyesera, chonde ndidziwitseni, ndipo ndingakhale wokondwa kuthandizapo.
1. Thupi la valavu ndi mawonekedwe a chivundikiro cha valve: Class150 ~ Class600 pogwiritsa ntchito chivundikiro cha valve; Class900 mpaka Class2500 imatenga chivundikiro cha valve yodzitchinjiriza.
2. Kutsegula ndi kutseka mbali (valavu chimbale) kapangidwe: valavu chimbale amapangidwa ngati kugwedezeka mtundu, ndi mphamvu zokwanira ndi kuuma, ndi kusindikiza pamwamba pa valavu chimbale akhoza pamwamba kuwotcherera zinthu golide kapena zoikamo sanali zitsulo malinga ndi wosuta. zofunika.
3. Vavu chivundikiro chapakati gasket mawonekedwe ochiritsira: Class150 valavu fufuzani ntchito zosapanga dzimbiri graphite gulu gasket; C|ass300 cheke valavu ndi zosapanga dzimbiri graphite bala gasket; Class600 chekeni vavu angagwiritsidwe ntchito zosapanga dzimbiri mwala 4. Inki yokhotakhota gasket angagwiritsidwenso ntchito zitsulo mphete gasket; Ma valve a Class900 mpaka Class2500 amagwiritsa ntchito mphete zachitsulo zodzikakamiza.
5. Fomu yogwiritsira ntchito: Fufuzani valve imatsegula kapena kutseka molingana ndi kayendedwe kapakati.
6. Mapangidwe a rocker: Wogwedeza ali ndi mphamvu zokwanira, ufulu wokwanira kutseka diski ya valve, ndipo ali ndi chipangizo chochepetsera kuti ateteze malo otsegulira kuti asakhale okwera kwambiri kuti atseke.
7. Mapangidwe a mphete yokweza: Valavu yoyang'ana zazikulu-caliber imapangidwa ndi mphete yonyamulira ndi chimango chothandizira, chomwe chiri choyenera kukweza.
Panthawi yotsegulira ndi kutseka kwa valve yachitsulo yopangidwa ndi zitsulo, chifukwa kukangana pakati pa diski ndi kusindikiza pamwamba pa thupi la valve ndi kochepa kuposa kwa valve yachipata, imakhala yosagwira ntchito.
Kutsegula kapena kutseka kwa tsinde la valve ndi kochepa kwambiri, ndipo kumakhala ndi ntchito yodalirika yodulira, ndipo chifukwa kusintha kwa doko la mpando wa valve kumakhala kofanana ndi kugunda kwa valve disc, ndikoyenera kwambiri kusintha. wa mlingo wotuluka. Choncho, valavu yamtunduwu ndi yoyenera kwambiri kudulidwa kapena kuwongolera ndi kugwedeza.
