Swing Type Check Valve

Lub viav vias kos valve yog tsim los ntawm lub cev valve, lub hau npog, lub rooj zaum valve, valve disc, rocker, pin, bracket thiab lwm yam. Lub valve disc tig ib ncig ntawm tus pin nyob sab nraum lub rooj zaum valve. Sab nraum qab ntawm lub valve disc yog tsau ntsia rau ntawm ib kawg ntawm lub rocker los ntawm ib tug txuas ntsia hlau thiab txiv ntseej, thiab lwm yam kawg ntawm lub rocker yog hingedly ntsia rau ntawm phab ntsa bracket ntawm lub valve lub cev kab noj hniav. Lub siab nruab nrab ntawm qhov kawg ntawm qhov nkag mus thawb lub valve disc kom tig thiab qhib, thiab qhov nruab nrab siab ntawm qhov hluav taws xob kawg thiab tus kheej qhov hnyav ntawm lub valve disc ua rau lub valve kaw.

Tsim qauv

Yuav ua li cas rau nruab ib lub viav vias kos valve?

Lub viav vias kos li qub tuaj yeem ntsia tau kab rov tav lossis ntsug. Ua ntej txhim kho lub viav vias kos valve, koj yuav tsum xyuas kom meej tias cov xub ntws nyob rau hauv qhov tseeb. Yog tias ntsia vertically, cov xub ntws yuav tsum taw tes rau pem hauv ntej kom tso cai rau cov kua ntws los ntawm cov yeeb nkab kom ntws mus rau sab saud thiab tsis txhob rub nws rov qab thiab ua rau cov dej tsis huv.

Cov kauj ruam hauv qab no yuav qhia koj txog yuav ua li cas rau nruab lub viav vias kos valve:

Kauj Ruam 1: Saib hauv lub valve
Xyuas kom tseeb tias tsis muaj dab tsi daig hauv lub cev valve. Yog tias ib qho khoom me me nkag mus rau hauv lub viav vias kos valve, nws yuav ua rau lub disc ntog, tiv thaiv tag nrho cov dej ntws.

Kauj ruam 2: Thawb lub disc tawm ntawm lub rooj zaum saum npoo thiab xyuas nws cov haujlwm kom paub tseeb tias nws tuaj yeem txav tau yooj yim.

Kauj Ruam 3: Xyuas kom tseeb tias cov flange kawg tsis muaj burrs lossis npoo uas tuaj yeem tiv thaiv kev sib khi kom raug.

Kauj Ruam 4: Txhim kho lub valve nyob rau hauv cov kev taw qhia ntws raws li qhov kev taw qhia ntws, kom ntseeg tau tias muaj cov yeeb nkab ncaj nraim ntawm 3 npaug ntawm txoj kab uas hla ntws.

Kauj Ruam 5: Yog tias ntsia vertically, cov kev taw qhia ntws yuav tsum nce siab; Yog tias ntsia kab rov tav, lub hau npog valve yuav tsum tig mus rau sab saud.
