Tsis-Load Khiav Valve

Nta

Nws yog qhov tshwj xeeb ceev kaw valve rau kev tiv thaiv chav turbine generator chav tsev.Nws yog tsim los tiv thaiv lub siab nyob rau hauv lub chav turbine los ntawm dheev poob thaum lub chav turbine dheev poob loads, thiab cov chav nyob rau hauv lub extraction yeeb nkab thiab ntau yam cua sov los ntawm ntws rov qab mus rau hauv chav turbine, ua rau lub chav turbine hniav uas tig ntawm ib tug. kev kub ceev ntawm ntau tshaj 3000 revolutions ib feeb kom dheev khiav nyob rau hauv rov qab, yog li ua rau ib tug disgusting kev huam yuaj uas lub chav turbine hniav yog tawg thiab lub chav turbine generator puas, thiab tiv thaiv dej rauj kev huam yuaj tshwm sim los ntawm leakage ntawm cov yeeb nkab pas dej ua ke ntawm lub rhaub. system thiab dej nkag mus rau hauv lub turbine los ntawm cov yeeb nkab extraction.Nyob rau hauv rooj plaub ntawm cov xwm txheej saum toj no, lub valve tuaj yeem raug kaw sai sai li ntawm 0.5s.

Daim ntawv thov:

1. Lub pneumatic nres callback yog thawb lub piston nyob rau hauv cov pa liab los ntawm compressed cua, lub piston thawb lub diav rawg hloov, thiab cov diav rawg ua haujlwm tsav lub rocker ncej tig los qhib lub valve.Lub valve raug kaw los ntawm kev thawb lub caij nplooj ntoos hlav daim phiaj piston rov qab los txiav tawm cov huab cua los ntawm kev hloov kho electromagnetic.

2. Lub sealing nto ntawm net khoom qab zib thiab ridge puag yog ua los ntawm cov ntaub ntawv surfacing tshiab, uas muaj zog hnav tsis kam thiab khawb tsis kam.

Nickel Base Alloy Siab Siab & Kub Ntsuas Valve

Nta:

Txhawm rau kom ntseeg tau qhov kev xav tau siab rau qhov nruj, kev ntseeg tau thiab kev nyab xeeb ntawm lub qhov rooj, lub valve lub cev yog ua los ntawm npib tsib xee puag alloy tag nrho, los yog fabricated thiab welded.Lub sealing nto ntawm lub qhov rooj valve yog welded nrog nyuaj alloy los txhim kho nws hnav tsis kam thiab khawb tsis kam, thiab txhim kho lub neej kev pab cuam ntawm lub sealing nto.Lub nruab nrab chamber ntawm lub qhov rooj dav adopts tus kheej sealing qauv, uas yog conducive rau high-pressure sealing.Qhov siab dua, lub sealing zoo dua.
