II.Txoj Kev Xeem thiab Kev Tshuaj Xyuas

1,CastingsZoo

Covcastingscov duab thiab qhov loj me yuav tsum ua raws li qhovkev xav tauntawm technical drawings thiab cov kev cai los ntawmtus thov.Covyam tsawg kawg nkausphab ntsa thickness ntawm valve qhov chaw, cov txheej txheem ntev yuam kev,kev puas tsuajnyiaj pub ntawmrooj phajyuav tsum tsis txhob qis tshaj qhov yuav tsum tau muaj nyob rau hauv cov khoom technical standard thiab cov khoom kos duab.Qhov saum npoo ntawm ntxhibvalvethiab lub plhaub siab ntawm cov khoom tiav valve yuav tsum tsis muaj kab nrib pleb,txias kaw, xuab zeb suav nrog, pore thiab lwm yam tsis xws luag.The adhering xuab zeb, sprue, riserthiaboxide tawvntawm castings nto yuav tsum tau ntxuav tawm.

2,SiabKuaj

Qhov kev ntsuam xyuas siab yog qhov ntau tshajyooj yimtest rau valve.Each valve yuav tsum tau nqa tawm rau kev ntsuas siab ua ntej xa los ntawm lub Hoobkas.Tnws sim siab thiab lub sij hawm ntev ua raws li txoj cai nyob rau hauvGB / T13927, thiab cov khoom kuaj npog lub plhaub kuaj thiab kuaj kev sib khi.Yog ib yam ntawmrov qabsealing qauv ntawm valve, nws yuav tsum tau uarov qab foob test. During cov txheej txheem xeem, lubzog sab nrauduas tej zaum yuav cuam tshuam qhov kev xeem yuav tsum tsis txhob siv rau valve.Kev ntsuas siab yuav tsum ua kom tsis tu ncua thaum lub sijhawm tuav lub zog thiab ntsuas.

Lub plhaub kuaj rau lub valve yog ib hom kev ntsuas siab rau tag nrho lub plhaub plhaub txuas nrog lub cev valve thiab npog.Nws lub hom phiaj yog los xyuas covcompactnessnruab nrab ntawm lub cev lub cev thiab lub hau npog, uas yog cov tshuaj tiv thaiv-siabmuaj peev xwm ntawm tag nrho lub plhaub nrog rau kev sib txuas ntawm lub cev valve thiab npog.

Covsealing xeem yog los xyuas qhov ua tau zoo ntawmon-off qhov chawthiab valvesealing khub, thiab muaj peev xwm muab faib ua high-pressure kua sealing test thiab low-pressure air sealing test.
