Kodi avalavu yowongolera kuthamanga?
Pamlingo woyambira, valavu yowongolera kupanikizika ndi chipangizo chopangidwa kuti chizitha kuwongolera kumtunda kapena kumunsi kwa mtsinje poyankha kusintha kwadongosolo. Kusintha kumeneku kungaphatikizepo kusinthasintha kwa kayendetsedwe kake, kupanikizika, kutentha kapena zinthu zina zomwe zimachitika panthawi yogwiritsira ntchito dongosolo. Cholinga cha chowongolera chowongolera ndikusunga dongosolo lofunikira. Chofunika kwambiri, owongolera kuthamanga amasiyana ndi ma valve, omwe amayendetsa kayendedwe ka kayendedwe kake ndipo sasintha zokha. Ma valve owongolera kuthamanga amawongolera kuthamanga, osati kuyenda, ndipo amadzilamulira okha.

Pressure regulator mtundu
Pali mitundu iwiri ikuluikulu ya ma valve owongolera kuthamanga:ma valve kuchepetsa kuthamanga ndi ma valve othamanga kumbuyo.

Ma valve ochepetsa kupanikizika amawongolera kuthamanga kwa njirayo pozindikira kuthamanga kwa kutuluka ndikuwongolera kutsika kwawo komwe

Zowongolera zowongolera zakumbuyo zimawongolera kupanikizika kuchokera panjirayo pozindikira kuthamanga kwa kulowa ndikuwongolera kuthamanga kuchokera kumtunda

Kusankha kwanu koyenera kwa owongolera kuthamanga kumatengera zomwe mukufuna. Mwachitsanzo, ngati mukufunikira kuchepetsa kupanikizika kuchokera ku gwero lapamwamba kwambiri musanayambe makina osindikizira asanafike pachimake chachikulu, valve yochepetsera mphamvu imatha kugwira ntchitoyo. Mosiyana ndi zimenezi, valavu yakumbuyo yam'mbuyo imathandiza kulamulira ndi kusunga kumtunda kwamtunda pochotsa kupanikizika kowonjezereka pamene machitidwe amachititsa kuti kupanikizika kukhale kwakukulu kuposa momwe kumafunikira. Mukagwiritsidwa ntchito pamalo abwino, mtundu uliwonse ukhoza kukuthandizani kuti mukhalebe ndi mphamvu zofunikira pa dongosolo lanu lonse.

Mfundo yogwira ntchito ya valve yowongolera kuthamanga
Ma valve owongolera kuthamanga ali ndi zinthu zitatu zofunika zomwe zimawathandiza kuwongolera kuthamanga:

Zida zowongolera, kuphatikiza mpando wa valve ndi poppet. Mpando wa valavu umathandizira kuwongolera kuthamanga ndikuletsa madzi kuti asadutse mbali ina ya chowongolera akatsekedwa. Pamene dongosolo likuyenda, mpando wa poppet ndi valve umagwirira ntchito pamodzi kuti amalize kusindikiza.

Sensing element, nthawi zambiri diaphragm kapena piston. Zomwe zimamva zimapangitsa kuti poppet adzuke kapena kugwa pampando wa valve kuti azitha kuwongolera kulowera kapena kutulutsa.

Loading Elements. Kutengera ndikugwiritsa ntchito, wowongolera akhoza kukhala wowongolera wamasika kapena wowongolera wodzaza dome. Chotsitsacho chimakhala ndi mphamvu yotsitsa yotsika pamwamba pa diaphragm.

Zinthu izi zimagwirira ntchito limodzi kuti zitheke kuwongolera kuthamanga komwe kumafunikira. Pistoni kapena diaphragm imamva kutsika kwa mtsinje (kulowetsa) ndi kutsika kwa mtsinje (kutuluka). Chidziwitsocho chimayesa kupeza mphamvu ndi mphamvu yokhazikitsidwa kuchokera ku chinthu chotsegula, chomwe chimasinthidwa ndi wogwiritsa ntchito pogwiritsa ntchito chogwirira kapena njira ina yokhotakhota. Chomverera chimathandiza poppet kutsegula kapena kutseka kuchokera pampando wa valve. Zinthu izi zimagwirira ntchito limodzi kuti zisungike bwino komanso kuti zitheke kukakamizidwa. Ngati mphamvu imodzi isintha, mphamvu ina iyeneranso kusintha kuti ibwezeretse mgwirizano.

Mu valve yochepetsera mphamvu, mphamvu zinayi zosiyana ziyenera kukhala zogwirizana, monga momwe tawonetsera pa Chithunzi 1. Izi zikuphatikizapo mphamvu yotsegula (F1), inlet spring force (F2), kutuluka kwa mpweya (F3) ndi kulowetsa (F4). Mphamvu yonse yotsegulira iyenera kukhala yofanana ndi kuphatikiza kwa mphamvu yolowera kasupe, kuthamanga kwa potuluka, ndi kukakamiza kolowera.

Ma valve othamanga kumbuyo amagwira ntchito mofananamo. Ayenera kulinganiza mphamvu ya kasupe (F1), kuthamanga kwa mpweya (F2) ndi kutulutsa mpweya (F3) monga momwe tawonetsera pa Chithunzi 2. Apa, mphamvu ya kasupe iyenera kukhala yofanana ndi kuchuluka kwa mphamvu yolowera ndi kutuluka.

Kupanga Kusankha kwa Right Pressure Regulator
Kuyika chowongolera choyezera bwino ndikofunikira kuti musunge kupanikizika komwe kumafunikira. Kukula koyenera nthawi zambiri kumadalira kuchuluka kwa kayendetsedwe ka kayendetsedwe kake - olamulira akuluakulu amatha kuyendetsa maulendo apamwamba pamene akuwongolera kuthamanga bwino, pamene kutsika kwapansi, olamulira ang'onoang'ono ndi othandiza kwambiri. Ndikofunikiranso kukula kwa zigawo zowongolera. Mwachitsanzo, zingakhale bwino kugwiritsa ntchito diaphragm kapena pisitoni yokulirapo kuti muchepetse kupanikizika. Zigawo zonse ziyenera kukhala zazikulu molingana ndi zomwe mukufuna pa dongosolo lanu.

Kupanikizika kwadongosolo
Popeza ntchito yayikulu yowongolera kupanikizika ndikuwongolera kukakamiza kwadongosolo, ndikofunikira kuwonetsetsa kuti owongolera anu ali ndi kukula kwakukulu, kocheperako, komanso kupanikizika kwadongosolo. Mafotokozedwe a mankhwala oletsa kukakamiza nthawi zambiri amawonetsa kuchuluka kwa kuwongolera, komwe ndikofunikira kwambiri pakusankha chowongolera choyenera.

Kutentha kwadongosolo
Njira zamafakitale zimatha kukhala ndi kutentha kwakukulu, ndipo muyenera kukhulupirira kuti chowongolera chomwe mwasankha chidzapirira momwe amagwirira ntchito. Zinthu zachilengedwe ndi chimodzi mwazinthu zomwe ziyenera kuganiziridwa, pamodzi ndi zinthu monga kutentha kwa madzi ndi mphamvu ya Joule-Thomson, yomwe imayambitsa kuzizira mofulumira chifukwa cha kutsika kwapakati.

tcheru ndondomeko
Kutengeka kwa njira kumakhala ndi gawo lofunikira pakusankha njira yowongolera muzowongolera zowongolera. Monga tafotokozera pamwambapa, owongolera ambiri ndi owongolera odzaza masika kapena owongolera omwe ali ndi dome. Mavavu owongolera kuthamanga kwa kasupe amayendetsedwa ndi woyendetsa potembenuza chogwirira chakunja chomwe chimawongolera mphamvu yamasika pa chinthu chozindikira. Mosiyana ndi izi, owongolera omwe ali ndi dome amagwiritsa ntchito mphamvu yamadzimadzi mkati mwadongosolo kuti apereke kupanikizika komwe kumagwira ntchito yozindikira. Ngakhale zowongolera zodzaza masika ndizofala kwambiri ndipo ogwiritsa ntchito amakonda kuzidziwa bwino, owongolera omwe ali ndi dome atha kuthandiza kuwongolera magwiridwe antchito omwe amafunikira ndipo amatha kukhala opindulitsa pamapulogalamu owongolera okha.

system media
Kugwirizana kwazinthu pakati pa zigawo zonse za pressure regulator ndi media media ndikofunikira kuti pakhale moyo wautali komanso kupewa nthawi yopumira. Ngakhale zida za mphira ndi elastomer zimawonongeka mwachilengedwe, ma media ena amachitidwe amatha kupangitsa kuti chiwopsezo chiwonjezeke komanso kulephera kwa ma valve owongolera msanga.

Ma valve owongolera kupanikizika amagwira ntchito yofunika kwambiri m'makina ambiri amadzimadzi ndi zida zamagetsi, zomwe zimathandiza kusunga kapena kuwongolera kupanikizika komwe kumafunikira ndikuyenda poyankha kusintha kwadongosolo. Kusankha chowongolera choyenera ndikofunikira kuti makina anu azikhala otetezeka komanso kuchita momwe amayembekezera. Kusankha kolakwika kungayambitse kulephera kwadongosolo, kusagwira bwino ntchito, kukonza zovuta pafupipafupi, komanso ngozi zomwe zingachitike pachitetezo.
