Parallel Ob Chav Disc Rooj Vag Valve Teeb Qhia

I. Npaj ua ntej kev teeb tsa
Cov cuab yeej tshuaj xyuas:

Tshawb xyuas seb lub cev valve, rooj vag thiab kev sib khi yog pub dawb los ntawm kev puas tsuaj, kev coj ua / hluav taws xob lub valve thiab cov ntaub ntawv hluav taws xob yog lawm.
Tshawb xyuas seb lub valve specifications (DN, qib siab) thiab kav dej siab) thiab cov raj xa dej zoo ib yam nkaus.
Cuab Yeej thiab Khoom Siv:

Npaj flange bolts, seading gaskets (graphite hlau Winding gasket tau pom zoo), roj, spanner, theem thiab ntawm.
Ii. Kev taw qhia thiab muab tso rau
Yuav tsum muaj cov kev xav tau ntsug:

Cov kev taw qhia xim: Yuav tsum muab cov kab ntsug, xuas teshw lossis Actuator lossis Actuator yog nyob rau sab saum toj kom ntseeg tau tias lub rooj sib luag tsis cuam tshuam los ntawm kev sib tsoo.
Flange dlheej: parallel sib ncag nrog lub raj xa hluav taws xob nrog rau kev zam ntawm lub cev validation ntawm lub cev valve vim yog yuam kev (ntsuas nrog qib).
Bypass valve kev teeb tsa (yog tias muaj):

Ua ntej kev teeb tsa, nws yog ib qho tsim nyog los qhib lub pas dej bypass kom sib npaug ntawm cov inlet thiab qhov hluav taws xob thiab txo cov khoom siv qhib (muaj feem xyuam rau cov tshuab siab).
III. Cov kauj ruam txheej txheem
Flange kev txuas:

Tso lub valve ntawm ob lub flanges, ntxig rau bolts thiab zawm lawv thaum pib kom kho cov flangelism, tom qab ntawd tshem tawm lub valve.
Weld lub Flange rau cov raj dej kom ntseeg tau tias cov vuam slag tsis poob rau hauv lub phab ntsa sab hauv tom qab vuam).
Valve Kho:

Rov qab rau nruab lub valve, raws li kab pheeb ces kaum kev txiav txim hauv 3 zaug tusyees zawm lub bolts (kawg lub zog raws li cov qauv kev cai).
Lub taub hau tag nrho yuav tsum tau kuaj seb puas muaj lub taub hau sab hauv yog ntau dua lossis sib npaug nrog kev cuam tshuam nrog tus npauj npaim phaj thiab raj.
Actuator commissioning:

Tom qab siv hluav taws xob cov hluav taws xob / pneumatic actuator, manually qhib nws mus rau 50% qhib kev ua kom pom tseeb tias qhov kev coj qhib thiab kaw tau zoo sib xws nrog qhov ntsuas tau.
Ntsuam xyuas tag nrho-mob stroke hloov ua kom ntseeg tau tias tsis muaj jamming (yuav tsum tau khaws chaw seem ntawm lub valve qia)
