Khoom Taw Qhia
Sandwich hom viav vias kos valve tiv thaiv kev thim rov qab los ntawm disc txav mus rau qhov sib npaug. Nrog rau qhov kev tsim no, lub disc yeej ib txwm nyob hauv txoj kev ntws. Lub disc yog lub caij nplooj ntoos hlav-loaded los pab nrog zaum. Cov tib phaj wafer nqa daim tshev li qub no tsis muaj lub kaus mom thiab yog mounted ntawm flanges. Lub pob valve no muaj qhov luv luv mus ncig thiab teb sai heev rau qhov nres lossis thim rov qab, txo qhov peev xwm rauj dej. Nws yog qhov zoo dua me ntsis dua li lub pob swash daim tshev valve ntawm kev txo qis dej rauj, tab sis nrog kev poob siab dua.
Hom kev kos valve no ua ke nrog kev tsim kho yooj yim tab sis muaj zog thiab kev ntseeg tau. Lawv tau tsim thiab tsim rau cov ntawv thov uas xav tau kev poob siab. Wafer style viav vias kos li qub muaj qhov ntev ntawm lub ntsej muag thiab qhov hnyav qis rau qhov yooj yim, txuag qhov chaw nruab nrab ntawm mating flanges.
Lub valve yog tsim rau kev teeb tsa ntawm cov qauv sib txawv pob tw vuam flanges lossis phaj hom mating flanges. Lub ntsej muag luv luv ntawm lub ntsej muag thiab qhov hnyav tsawg lav qhov yooj yim thiab txuag chaw nruab nrab ntawm cov bolts txuas cov flanges. Kev sib xyaw ua ke ntawm eccentric disk ncej kev sib txuas thiab lub rooj zaum disk ua kom ntseeg tau tias kev kaw haujlwm ntawm qhov nruab nrab rov qab los. Vim lawv cov qauv tsim thiab tus nqi qis, wafer kos li qub tau dhau los ua hom kev kos valve rau feem ntau daim ntawv thov. Wafer check li qub kuj muaj nyob rau hauv lub caij nplooj ntoos hlav loaded versions raws li kev thov tshwj xeeb.
Khoom Paub meej
Qhov no wafer check valve nta luv, qhaub cij style tsis-flammable wafer lub cev uas ua tau raws li API 6D thiab ASME B 16.10 lub ntsej muag-to-face dimensions. Yooj yim hauv kev tsim kho tab sis txhim khu kev qha thiab ruaj khov, lub valve no yog qhov zoo tagnrho rau cov dej ntws tawm. Lub eccentrically mounted pob khawm tus pin ua ke nrog lub rooj zaum disc kom muaj txiaj ntsig zoo ntawm qhov nruab nrab rov qab. Ntawm qhov kev thov tshwj xeeb, lub caij nplooj ntoos hlav loaded version ntawm wafer check valve kuj muaj. Wafer check li qub yog tsim rau kev teeb tsa ntawm cov qauv sib txawv weld caj dab lossis slip-on counterpart flanges. Vim lub ntsej muag foob "O" rings ntawm lub ntsej muag sealing, tsis muaj flange gaskets yuav tsum tau thaum lub sij hawm installation. Lub ntsej muag lub ntsej muag luv luv thiab lub teeb yuag tso cai yooj yim installation ntawm mating flanges, txuag chaw.
Nta
- Lub ntsej muag-rau-lub ntsej muag qhov ntev me me, yog li qhov chaw xav tau rau kev teeb tsa tsawg dua 10 feem pua ntawm cov pa li qub i].
- Lub teeb hnyav heev - qhov hnyav tag nrho tsuas yog kwv yees li 1/6 ntawm qhov hnyav ntawm cov tshuaj xyuas li qub.
- Lub cev luv luv wafer tso cai rau lub valve yuav tsum tau mounted siv lub luv luv thiab tsawg fasteners tshaj flanged viav vias kos li qub. Fastener tus nqi txuag ntawm li 50 feem pua.
- Cov txiaj ntsig tseem ceeb thib ob pub rau kev txuag nyiaj tseem ceeb hauv kev tuav, ntim, thauj, teeb tsa thiab kho.
- Kev txuag ntawm qhov ntev tag nrho uas xav tau rau cov kav dej.
- Tsawg nruj torque siv rau mating flange bolts vim lub ntsej muag foob O-rings.
- Vim muaj qhov tsawg tsawg ntawm cov khoom thiab cov qauv yooj yim, nws yuav luag tsis muaj txij nkawm.
- Self-centering nyob rau hauv cov yeeb nkab vim tswj txheej kab uas hla, yooj yim rau nruab.
Kev siv thiab kev ua haujlwm
Sandwich hom viav vias kos valve siv lub viav vias disc kom tso cai lossis thaiv kev ntws. Lawv tau tsim los kom lawv tuaj yeem ntsia tau rau hauv qhov chaw nruj heev - qhov chaw uas flanged check li qub tsis tuaj yeem siv. Wafer check li qub muaj lub cev molded nyob ib ncig ntawm qhov chaw uas lub clapper qhib. Qhov no yog qhov sib txawv tseem ceeb tshaj plaws ntawm ob hom li qub tau hais los saum no.
Thaum xub thawj siab ib muag no tej zaum yuav zoo li ib tug mere qhov teeb meem, lub xub ntiag ntawm lub valve lub cev muaj feem xyuam rau lub functionality ntawm lub valve piv rau yooj yim wafer soj ntsuam. Vim tias flanged check li qub yog flanged rau hauv qhov chaw, tsis muaj chaw txaus hauv cov kav dej rau lub disc qhib. Qhov no txhais tau hais tias ntws feem ntau txwv nyob rau hauv lub check valve.
Kev txhim kho thiab tu
- Tsis xav tau kev saib xyuas, yooj yim los hloov cov khoom seem.
- Nruab rau ntawm cov yeeb nkab yam tsis muaj gaskets ntxiv.
- Ntev caj dab tsim rau kev siv rwb thaiv tsev.
- Lub caij nplooj ntoos hlav muaj nuj nqi ntawm disc tuaj yeem ntxiv rau kev thov.
