Amagwiritsidwa ntchito ngati nthunzi, madzi ndi mapaipi ena osawononga sing'anga amapopa kapena machitidwe ena pafakitale yamagetsi, chinthucho ndi chowonjezera chofunikira kwambiri cha jenereta yotentha kuti chiteteze magwiridwe antchito otetezeka a turbine ya nthunzi. Monga chipangizo choletsa kusuntha kwapakati, valavu imatha kutseka mwachangu komanso mwamphamvu kuti iwonetsetse kuti makina opangira nthunzi amalekanitsa mwachangu ndikupatsanso makina opangira nthunzi kapena makina opopera ndi chitetezo chokwanira pambuyo poti chipangizo cha pneumatic chilandira chizindikiro chosinthika chamadzimadzi ngati chotenthetsera chamadzi chikatuluka. ali ndi mulingo wapamwamba kwambiri wamadzi.
- Mpando wa valve ndi thupi zimatengera mawonekedwe ophatikizika, okhala ndi 25 ° kuphatikiza mbali pakati pa mpando wa valve ndi chitoliro chanthambi. Poganizira kuti palibe kukana koyenda, kutsekeka kotseka kumafupikitsidwa kuti zitsimikizire kutseka kofulumira ndi kusindikiza valavu ndi nthawi yotseka ya valve ndi yochepera 0.5s.
- Ndi mawonekedwe amtundu wa swing, disc ya valve imathandizidwa ndi tsinde la valve mu thupi la valve. Mapeto onse a tsinde la valve amathandizidwa ndi manja otsogolera pa thupi la valve. Ndi Stellite alloy build-up welding, kusindikiza pamwamba sikuchepera 3mm mutatha kukonza ndipo kuuma kwake kumakhala ndi kusiyana kolimba poyerekeza ndi kuuma kwa mpando wa valve.
- Valavu imayikidwa ndi makina ena ozungulira pneumatic. Pamene mpweya wa pneumatic uli pa malo ake otsegulira, diski ya valve siinatsegulidwe kapena kutsekedwa ndi pneumatic actuator, yomwe imatha kuzungulira momasuka; valavu ikhoza kutseka yokha ngakhale actuator sikugwira ntchito. Pakutseka kwake, woyendetsa pneumatic amagwiritsa ntchito mphamvu yothandizira pa diski ya valve kuti atsimikize nthawi yotseka ndi kusindikiza kudalirika kwa valve.
- Boneti ya valve imatengera mawonekedwe apakati a flange ndipo chosindikizira chimatenga gasket yotsekera kuti isindikize, yokhala ndi kusindikiza kodalirika komanso kuphatikizika kosavuta.
- Kwa valavu yokhala ndi mphamvu yochepa yogwira ntchito, nyundo yonyowa yonyowa imayikidwa pa tsinde la valve kuti igwirizane ndi mphamvu yokoka ya diski ya valve ndi mbali zina zotseka; wokhoza kuonetsetsa kuti ma valve atsegulidwa mokhazikika komanso kuchepetsa kugwedezeka pakuyenda kutsogolo kwa sing'anga yotsika.
- Ndi mapangidwe owongolera, mkati mwa thupi la vavu lachepetsa kukana kwa ma valve ndi mphamvu yothamanga kwambiri.
- Ndi kusintha kwapang'onopang'ono kwapang'onopang'ono, chowotcha cha pneumatic chimatha kuyang'anira momwe akuzimitsa patali.
- Mapangidwe a valve ali ndi nyundo yolemera kapena mitundu yopanda nyundo yolemera.
- Vavu ili ndi chipangizo choyesera chamanja cha pneumatic actuator. Kuyesa kwapaintaneti kwapang'onopang'ono kwa silinda kumazindikirika ndi mavavu amanja ndi ma throttle kuti apewe kusagwira ntchito kwanthawi yayitali kwa ma valve ndi silinda pakugwira ntchito, kupereka zotsimikizira zogwirira ntchito bwino.
