Chitsanzo 1
Mawonekedwe:
Ndi ma multistage throttling mkati, manja amtundu wa khola amafanana ndi singano yamtundu wa singano, yomwe imatha kupirira kupsinjika kwakukulu.Mpando wokonzekera umakanikizidwa ndikusindikizidwa paokha, ndipo mawonekedwe osindikizira a conical ndi odalirika.Itha kufananizidwa ndi maziko osinthira osalingana kuti akwaniritse kutayikira kwa zero.Mbali yamkati imawumitsidwa ndi chitsulo chosapanga dzimbiri, chomwe chimalimbana ndi kukokoloka ndipo chimakhala ndi moyo wautali wautumiki.The single siteji kuthamanga kusiyana ndi kuchepetsedwa, kotero kuti malamulo osiyanasiyana kukodzedwa.Makamaka mukuyenda kwakung'ono, kumakhalabe ndi machitidwe abwino owongolera.Kuthamanga kwa dontho la gawo lirilonse kudzayendetsedwa mkati mwa kusiyana kwakukulu kwa kuthamanga popanda cavitation ndi kung'anima.Chilolezo chokhala ndi kusintha kwakukulu ndi koyenera, ndipo dzanja lotsogolera limakhala ndi kalozera wabwino komanso ntchito yokhazikika.Valve imasinthasintha pogwira ntchito komanso yolondola pakusintha.
Mapulogalamu:
Boiler overheat, reheater, spray desuperheating system, low pressure bypass water spray desuperheating system.Kupopera madzi desuperheating dongosolo ndi pressure regulator kwa desuperheating mankhwala ndi gawo.Valavu imatha kusintha kayendedwe kakang'ono, ndi kusintha kwakukulu kosinthika ndi ntchito yokhazikika.

Power Station High Pressure Minimum Flow Control Valve
Mawonekedwe:
Valavu ikhoza kusinthidwa mosalekeza mkati mwa kupanikizika kwakukulu kosiyana;Mipikisano siteji throttling anatengera, sing'anga pang'onopang'ono depressurized, ndi kuthamanga dontho la siteji iliyonse ndi mu osiyanasiyana gasification kuthamanga dontho, ndi cavitation kukana ndi otsika phokoso.Kusintha kwapakati kumatengera mawonekedwe osakhala athyathyathya amisewu, okhala ndi mpando wa monotone ndi chisindikizo chojambulidwa, chomwe chimakhala ndi ntchito yabwino yosindikiza ndipo chitha kutulutsa zero dziwe.Kapangidwe ka manja ndi porous khola mtundu, ndipo mabowo ang'onoang'ono anakonza mosamalitsa malinga ndi zofunika kusintha makhalidwe.Ndi kulumikizana koyenera pakati pa pachimake cha valve ndi mpando wosinthira manja, njira yosinthira imakhala ndi kutayikira kochepa, ndikuwongolera molondola.Magawo apamwamba ndi apansi a pachimake chowongolera amakhala ndi manja owongolera, omwe amatsimikizira kusintha kokhazikika, kusagwedezeka, komanso kudziyeretsa mwamphamvu.Labyrinth kapangidwe, sing'anga axial flow, stepwise kuchepetsa kuthamanga kudzera multistage throttle disc, petulo kugonjetsedwa, phokoso lochepa ndi ntchito khola.
Mapulogalamu:
Valve yocheperako yoyendetsera kayendetsedwe kake imagwiritsidwa ntchito pobwezeretsanso gawo lamadzi ku tanki ya deaerator pamene katundu wa unit ali wochepa kuti ateteze mpope wa chakudya kuti usatenthedwe ndi kutentha, ndikuonetsetsa kuti pampu ya chakudya ikugwira ntchito.Valavu iyi imapangidwa makamaka ndikupangidwira mawonekedwe a kusiyana kwakukulu kwa chakudya cham'mimba, kusagwira bwino ntchito, kuthamanga kwapakati, komanso kukokoloka kwakukulu ndi cavitation zamkati.Itha kugwiritsidwa ntchito limodzi ndi mapampu opangira chakudya cha 100MW/125MW/200MW/500MW.

Power Station High Pressure Water Control Valve
Mawonekedwe:
Chivundikiro cha valve chimatengera mawonekedwe osindikizira oyera kapena mtundu wa flange, kusintha kwamtundu wa khola la manja, chisindikizo cha mpando umodzi, komanso kutayikira kwakukulu.Malo osindikizira amapangidwa ndi simenti ya carbide, ndipo pamwamba pa gawo lamkati amawapopera ndi chinthu chimodzi chosagwira ntchito, chokhala ndi moyo wautali wautumiki.Chisindikizo ndi chitsulo chilonda gasket ndi analimbitsa flexible mwala inki, kusindikiza odalirika.
Mapulogalamu:
Amagwiritsidwa ntchito poyang'anira kayendedwe ka madzi, ndi kusindikiza kodalirika, kutayikira kwakukulu komanso moyo wautali wautumiki.Njira yoperekera madzi, kupopera madzi kutentha.Main malamulo operekera madzi a boiler.
