Pneumatic Two-piece Ball Valve

1. Makhalidwe a valavu ya pneumatic ya zidutswa ziwiri za mpira

Mpweya wamagetsi wamitundu iwiri ya mpira, wokhala ndi mawonekedwe ake apadera komanso kapangidwe kake, ukuwonetsa maubwino ofunikira pakuwongolera madzimadzi. Choyamba, mawonekedwe a magawo awiri amapangitsa kukhazikitsa ndi kukonza ma valve kukhala kosavuta pamene kuchepetsa ndalama zopangira. Kachiwiri, ngati chinthu chowongolera, gawoli lili ndi mawonekedwe amphamvu yozungulira komanso kukana kochepa, komwe kumatha kuwonetsetsa kuyenda bwino kwa sing'anga mu payipi. Kuphatikiza apo, valavu ya mpira wamitundu iwiri ya pneumatic ilinso ndi izi:

Kuchita bwino kusindikiza: Kuyenerera koyenera komanso zipangizo zosindikizira zapamwamba zimagwiritsidwa ntchito pakati pa mpira ndi mpando wa valve kuti zitsimikizire kuti valavu ilibe kutayikira ikatsekedwa, kuteteza kuteteza mphamvu zowonongeka.
Kukana kwamphamvu kwa dzimbiri: Thupi la vavu nthawi zambiri limapangidwa ndi zinthu zosapanga dzimbiri monga chitsulo chosapanga dzimbiri, chomwe chimatha kuzolowera zinthu zosiyanasiyana zowononga ndikuwonetsetsa kuti valavu imagwira ntchito bwino m'malo ovuta.
Yosavuta kugwiritsa ntchito: Woyendetsa pneumatic amayendetsa mpira kuti uzungulire kudzera mumpweya woponderezedwa kuti ukwaniritse kutsegula ndi kutseka mwachangu, kosavuta kugwira ntchito komanso kuyankha mwachangu.

2. Kugwiritsa ntchito valavu ya pneumatic-piece-ball valve mu kayendetsedwe ka mphamvu

Ma valve opangidwa ndi pneumatic-piece-ball valves ali ndi mwayi wogwiritsa ntchito kwambiri pankhani ya kasamalidwe ka mphamvu. Zotsatirazi ndizochitika zingapo zomwe zimagwiritsidwa ntchito:

Kuwongolera kayendedwe ka mapaipi: Mu petrochemical, mphamvu yamagetsi, zitsulo ndi mafakitale ena, mavavu amtundu wa pneumatic awiri-piece amagwiritsidwa ntchito kwambiri pamapaipi kuti athe kuwongolera kuyenda ndi kuthamanga kwa sing'anga. Mwa kusintha molondola kutsegula kwa valve, kuwongolera bwino kwa madzi othamanga kumatheka ndipo mphamvu zowonjezera mphamvu zimakongoletsedwa.
Dongosolo lakubwezeretsa mphamvu: Mu dongosolo lobwezeretsa mphamvu, valavu ya mpira wamtundu wa pneumatic ingagwiritsidwe ntchito kuwongolera kuyenda kwa sing'anga yobwezeretsanso kuti zitsimikizire bwino komanso chitetezo cha njira yochira. Chepetsani kutayika kwa mphamvu komanso konzani zobwezeretsanso mphamvu poyankha mwachangu komanso kuwongolera moyenera.
Makina Otenthetsera ndi Kuziziritsa: M'makina otenthetsera ndi kuziziritsa, ma valve a mpira wamtundu wa pneumatic atha kugwiritsidwa ntchito kuwongolera kuyenda ndi kutentha kwa madzi otentha, madzi ozizira ndi media zina. Kupyolera mu kuwongolera mwanzeru, kusintha kolondola kwa makina otenthetsera ndi kuziziritsa kumatheka, kugwiritsa ntchito mphamvu kwamphamvu kumakhala bwino, ndipo mphamvu yogwiritsira ntchito mphamvu imachepetsedwa.

3. Ubwino wa valavu ya pneumatic-piece-ball valve mu kayendetsedwe ka mphamvu

Mavavu opangidwa ndi pneumatic-piece-ball valves ali ndi maubwino ofunikira pantchito yowongolera mphamvu. Choyamba, mphamvu zake zowongolera bwino komanso zodalirika zamadzimadzi zimathandiza kukwaniritsa kuwongolera bwino komanso kugwiritsa ntchito mphamvu moyenera. Kachiwiri, kuyankha mwamsanga ndi kuwongolera kolondola kwa mpweya wa pneumatic actuator kumathandiza valavu kuti igwirizane ndi kusintha kwa dongosolo ndikuonetsetsa kuti dongosololi likugwira ntchito mokhazikika. Kuphatikiza apo, mavavu a mpira wamitundu iwiri a pneumatic alinso ndi izi:

Kupulumutsa mphamvu ndi kuteteza chilengedwe: Poyendetsa bwino kayendedwe ka madzimadzi, kuwononga mphamvu ndi kuwononga chilengedwe kumachepetsedwa, kukwaniritsa zofunikira za chitukuko chokhazikika.
Kuwongolera mwanzeru: Vavu yamagulu awiri a pneumatic amatha kulumikizidwa mosasunthika ndi machitidwe owongolera monga PLC ndi DCS kuti akwaniritse kuwongolera ndi kasamalidwe mwanzeru ndikuwongolera kasamalidwe ka mphamvu.
Chepetsani ndalama: Mtengo wopangira valavu ya mpira wa pneumatic-piece ndi yotsika. Panthawi imodzimodziyo, ntchito yake yabwino kwambiri komanso yodalirika imatha kuchepetsa mtengo wokonza ndi kulephera kwa dongosolo, kupulumutsa ndalama kwa ogwiritsa ntchito.

4. Mapeto

Monga chipangizo chowongolera bwino komanso chodalirika chamadzimadzi, valavu ya mpira wa pneumatic iwiri imakhala ndi gawo lofunikira pakuwongolera mphamvu. Mapangidwe ake apadera ndi mapangidwe ake amathandiza kuti valavu ikhale ndi ntchito yabwino komanso yodalirika, ndipo imatha kukwaniritsa zosowa zamadzimadzi pansi pa zovuta zosiyanasiyana zogwirira ntchito. Mwa kuwongolera bwino kayendedwe ka madzi ndi kukhathamiritsa kugwiritsa ntchito mphamvu moyenera, ma valve a mpira wamitundu iwiri amapereka chithandizo champhamvu pakuwongolera mphamvu ndikulimbikitsa chitukuko chokhazikika chamakampani.
