DIN 3357 pob valve yog German tus qauv flanged pob valve.
TIAB SA 3357Flanged Pob Valveyog lub valve uas tau tsav los ntawm tus cab iav mechanism, uas ua tiav qhov qhib, kaw, thiab ntws kev tswj ntawm cov kav dej tawm los ntawm kev tig lub pob. Nws lub nominal siab yog li ntawm PN1.0 mus rau 32.0 MPa, nrog ib tug nominal txoj kab uas hla ntawm DN6 mus rau 900, thiab yog haum rau kub ncua sij hawm ntawm -196℃mus rau 540 degree.
Txoj Cai Ua Haujlwm:
Cov tswv cuab kaw (pob) ntawm flanged pob valve yog tsav los ntawm lub valve qia thiab tig ib ncig ntawm lub axis ntawm lub valve qia. Thaum lub pob valve thawb lub valve core (pob), lub valve core txav raws li lub rooj zaum valve. Thaum lub valve tub ntxhais mus txog ib txoj hauj lwm, nws tswj qhov ntws ntawm qhov nruab nrab, yog li ua tiav lub hom phiaj ntawm kev tswj dej ntws. Hauv kev siv tswv yim, lub kaum sab xis ntawm lub flanged pob valve feem ntau yog 90 degrees. Thaum lub valve qia tsav lub pob kom tig 90 degrees, txoj kab ntawm lub pob sib haum nrog los yog txiav tawm ntawm txoj kev ntawm lub rooj zaum valve, yog li ua tiav qhov qhib lossis kaw.
