Kodi ma valve a mapaipi ndi otani: mpira/chipata/cheke/ma valve a padziko lonse lapansi

Ma Vavulo a PaipiAmagwira ntchito yofunika kwambiri mu machitidwe a mapaipi. Ndi amitundu yosiyanasiyana ndipo amagwira ntchito zosiyanasiyana. Pantchito ya tsiku ndi tsiku, nthawi zambiri timamva mayina osiyanasiyana a ma valve, omwe nthawi zina amasokoneza. Pofuna kuthandiza aliyense kumvetsetsa bwino ma valve, makamaka mitundu yofala, ndinaganiza zopanga chithunzithunzi cha mitundu yofala ya ma valve. Ndikukhulupirira kuti izi zingathandize aliyense. Tiyeni tifufuze chinsinsi cha ma valve pamodzi. Tiyeni tiphunzire za ma valve a mapaipi omwe amagwiritsidwa ntchito kwambiri.

Amagwiritsidwa Ntchito KawirikawiriMa Vavulo a Paipindi motere

Valavu ya mpira

• Kufotokozera mwachidule mfundo yogwirira ntchito:Gawo lalikulu la valavu ya mpira ndi chipolopolo chokhala ndi dzenje. Mfundo yake yogwirira ntchito imachokera pa kuzungulira kwa chipolopolochi kuti chiwongolere kuyatsa ndi kutseka kwa madzi. Ingozungulirani madigiri 90, ndipovalavu ya mpiraikhoza kukwaniritsa kusinthana kwathunthu kotseguka kapena kotsekedwa kwathunthu, komwe ndikosavuta komanso mwachangu kugwira ntchito.
• Mawonekedwe:Kugwira ntchito bwino kwambiri potseka, kugwiritsa ntchito mosavuta, kukana madzi pang'ono, kapangidwe kake kabwino komanso kosavuta kumva, kosavuta kutsegula ndi kutseka mwachangu.
• Chitsanzo cha ntchito:Amagwiritsidwa ntchito kwambiri pochiza madzi, petrochemical, kayendedwe ka gasi wachilengedwe ndi zina, makamaka oyenera zosowa za makina owongolera okha.

Ma valve a chipata

• Mfundo yogwirira ntchito:Valavu iyi imalamulira kuyenda kwa madzi mwa kukweza chipata, chomwe chili choyenera kwambiri pa ntchito yotseguka kapena yotsekedwa bwino, koma sichiyenera nthawi zomwe zimafuna kusintha kolondola kwa kayendedwe ka madzi.
• Mawonekedwe:Valavu ya chipata ili ndi magwiridwe antchito abwino otsekera, koma imatenga nthawi yayitali kusinthasintha, ndipo siyoyenera kugwiritsidwa ntchito pafupipafupi.
• Zochitika zogwiritsira ntchito:Amagwiritsidwa ntchito makamaka m'mapaipi akuluakulu komanso amphamvu kwambiri kuti athetse madzi monga madzi, nthunzi, mafuta ndi gasi wachilengedwe.

Valavu ya gulugufe

• Mfundo yogwirira ntchito:Kapangidwe ka valavu ya gulugufe kamapangidwa kuti kakhale kakang'ono kwambiri, kakang'ono komanso kopepuka. Kamapangitsa kuti madzi aziyenda bwino kapena kuti madzi azidulidwa bwino pozungulira mbale ya gulugufe.
• Mawonekedwe:Imatseguka ndi kutsekedwa mwachangu, koma kutsekako ndi kofooka.
• Zochitika zogwiritsira ntchito:Ndi yoyenera kwambiri pa mapaipi akuluakulu, osapanikizika kwambiri, monga madzi ndi ngalande, kayendedwe ka madzi ozizira ndi zina.

Valavu ya padziko lonse

• Mfundo yogwirira ntchito: Mwa kuzunguliza gudumu lamanja, diski ya valavu imayendetsedwa kuti isunthire mmwamba ndi pansi, motero imapangitsa kuti madzi aziyenda bwino. Kapangidwe kameneka ndi koyenera makamaka pazochitika zomwe zimafuna kusintha kayendedwe ka madzi ndi kugwira ntchito pafupipafupi.
• Mawonekedwe:Kugwira ntchito bwino kwambiri potseka, kutsegula ndi kutseka mwachangu, koma kukana madzimadzi kwakukulu, kapangidwe kovuta, zomwe zimapangitsa kuti kuthamanga kwa magazi kuchepe kwambiri.
• Kugwiritsa ntchito:Makamaka yoyenera mafakitale omwe amafuna malamulo okhudza kayendedwe ka madzi, monga ma boiler, makina a HVAC, ndi mapaipi a nthunzi.

Valavu yowunikira

• Mfundo yogwirira ntchito:Ili m'gulu la ma valve odziyimira pawokha, omwe amaletsa kubwerera kwa medium ndikuteteza payipi kuti isawonongeke ndi mphamvu ya nyundo ya madzi. Imatchedwanso check valve, one-way valve, reflux valve kapena isolation valve. Valve disc movement mode imagawidwa m'mitundu yokweza ndi swing.
• Mawonekedwe:Ntchito ya valavu yamtunduwu ndikulola kuti cholumikizira chiziyenda mbali imodzi yokha ndikuletsa kuti chiziyenda mbali ina. Ndi gawo lofunikira kwambiri kuti makinawo akhale otetezeka.
• Chitsanzo cha ntchito:Chogwiritsidwa ntchito kwambiri m'zida monga ma boiler ndi zotengera zopanikizika, valavu yowunikira imagwiritsidwa ntchito limodzi ndi valavu yoyimitsa kuti igwire ntchito yoteteza.

Valavu yothandizira kupanikizika

• Mfundo yogwirira ntchito:Pamene kuthamanga kwa makina kukupitirira malire omwe adakhazikitsidwa kale, valavu yotetezera imayamba yokha kutulutsa kuthamanga kwambiri kuti iwonetsetse kuti zida ndi makinawo sizikuwonongeka ndi kupanikizika kwambiri. Kupanikizika kukatsika kufika pamalo otetezeka, valavuyo idzatseka yokha ndikubwerera mwakale.
• Mawonekedwe: Kuchepetsa kupanikizikaMa valve amadziwika kuti ndi osavuta kugwiritsa ntchito. Amatha kuyankha mwachangu komanso modzidzimutsa kusintha kwa kuthamanga kwa mpweya mu dongosolo, zomwe zimathandiza kuti kuthamanga kwa mpweya kusapitirire muyezo, motero kuonetsetsa kuti zipangizozo zikugwira ntchito bwino.
• Zochitika zogwiritsira ntchito:Ma valve oteteza amagwiritsidwa ntchito kwambiri poteteza zipangizo monga ma boiler, ziwiya zopondereza, ndi mapaipi, ndipo ndi zida zofunika kwambiri zotetezera.

Vavu ya chida (valavu ya singano)

• Mfundo yogwirira ntchito:Mwa kuzunguliza gudumu lamanja, pakati pa valavu ya singano pakhoza kuyendetsedwa kuti isunthire mmwamba ndi pansi, motero kuzindikira malamulo olondola ndi kuwongolera kayendedwe ka madzi.
• Mawonekedwe:Ili ndi njira yowongolera kayendedwe ka madzi molondola komanso kutseka bwino, ndipo ndi yoyenera makamaka makina amphamvu komanso ang'onoang'ono oyendera madzi, koma liwiro lotsegula ndi kutseka ndi lochepa.
• Zochitika zogwiritsira ntchito:Ma valve olumikizira amagwiritsidwa ntchito kwambiri mu zida za labotale, machitidwe owongolera mpweya kapena madzi, komanso njira zowongolera kuthamanga kwamphamvu komanso kuyenda pang'ono.

Valavu ya pulagi

• Kufotokozera mfundo yogwirira ntchito:Valavu yolumikizira imasintha malo olumikizirana a njira yolumikizira ndi payipi pozungulira pulagi yozungulira kapena yopingasa kuti igwire ntchito yotsegula ndi kutseka madzi.
• Mawonekedwe:Valavu yolumikizira ili ndi kapangidwe kakang'ono, kosavuta kugwiritsa ntchito, ndipo imatsegula ndi kutseka mwachangu, zomwe ndizoyenera kwambiri pazochitika zomwe zimafuna kusinthana pafupipafupi.
• Madera ogwiritsira ntchito:Imagwira ntchito yofunika kwambiri m'mapayipi a gasi wachilengedwe, mafuta ndi mankhwala, ndipo imagwiritsidwa ntchito kwambiri polamulira madzi m'magawo awa.

Valavu ya Solenoid

• Mfundo yogwirira ntchito:Mu valavu ya solenoid, mphamvu yoyatsa ndi kutseka ya coil ya electromagnetic imayambitsa kusintha kwa mphamvu ya electromagnetic, zomwe zimapangitsa kuti valavu iyende bwino kuti itsegule kapena kutseka valavu. Pamene coil ya electromagnetic yatha mphamvu, valavu ya core idzayambiranso ndipo valavu idzatseka.
• Mawonekedwe:Valavu yolumikizira imayankha mwachangu ndipo imathandizira kulamulira kwakutali, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito mumakina odziyimira pawokha.
• Zochitika zogwiritsira ntchito:Imagwira ntchito yofunika kwambiri mu makina owongolera okha, mwachitsanzo, powongolera okha kutsegula ndi kutseka mapaipi amadzi, gasi ndi mafuta. Komabe, pali mitundu yambiri ya ma valve, osati ma valve omangirira okha.

IChidule cha n

Ma valve a mapaipi ndi zinthu zowongolera mu makina operekera madzi a mapaipi, zomwe zimagwira ntchito monga kutseka, kulamulira, kusinthasintha, kupewa kubwerera kwa madzi, kukhazikika kwa kuthamanga kwa madzi, kusinthasintha kwa madzi kapena kuchepetsa kuthamanga kwa madzi. Ma valve omwe amagwiritsidwa ntchito mu makina owongolera madzi ali ndi mitundu yosiyanasiyana komanso zofunikira.
