Mukuwona "vavu ya mgwirizano" ndi "valavu ya mpira" zalembedwa, koma kodi ndizosiyana? Kusankha molakwika kumatanthauza kuti mungafunike kudula valavu yabwino kwambiri pambuyo pake kuti mungogwiritsa ntchito mpope.
Valavu ya mpira imafotokoza njira yotsekera (mpira). Mgwirizano umalongosola mtundu wa kugwirizana womwe umalola kuchotsa (mtedza wa mgwirizano). Iwo sali ogwirizana; valavu yosunthika kwambiri ndivalavu ya mpira wowona, zomwe zimaphatikiza mbali zonse ziwiri.
Ichi ndi chimodzi mwazinthu zosokoneza zomwe ndikuwona, ndipo ndizosiyana kwambiri kwa akatswiri aliwonse. Nthawi zambiri ndimakambirana izi ndi mnzanga Budi ku Indonesia, chifukwa makasitomala ake amafunikira njira zomwe sizothandiza komanso zogwira mtima kuti zisungidwe pakapita nthawi. Chowonadi ndi chakuti, mawuwa amafotokoza zinthu ziwiri zosiyana: imodzi imakuuzaniBwanjivalavu imagwira ntchito, ndipo winayo amakuuzanimomwe zimalumikiziranaku pipo. Kumvetsetsa kusiyana kumeneku ndikofunika kwambiri popanga dongosolo lanzeru, lothandizira.
Kodi pali kusiyana kotani pakati pa valavu ya mpira ndi valavu ya mpira wa mgwirizano?
Mwayika valavu yokhazikika ya mpira, ndikuyiyika pamzere. Chaka chotsatira, chisindikizo chimalephera, ndipo mumazindikira kuti njira yanu yokha ndiyo kudula valve yonse ndikuyambanso.
Valavu yokhazikika ya mpira ndi gawo limodzi lokhazikika. Valavu yowona ya mpira wamagetsi yatulutsa mtedza womwe umakulolani kuchotsa valavu yapakati popanda kudula chitoliro, kupanga kukonza kapena kusintha kosavuta.
Uku ndiye kusiyana kofunikira kwambiri pakukonzekera kwanthawi yayitali. Ganizilani izi molingana ndi mawu akuti "okhazikika" motsutsana ndi "othandizira". Vavu yokhazikika, yophatikizana ya mpira imakhala yosungunulira molunjika mu payipi. Ikalowa, imakhala yabwino. Izi ndi zabwino kwa mizere yosavuta, yosafunikira. Avalavu ya mpira wowona, komabe, analinganizidwira mtsogolo. Inu zosungunulira-kuwotcherera tailpieces awiri osiyana chitoliro, ndi valavu waukulu thupi amakhala pakati pawo. Zimagwiridwa ndi mtedza waukulu wa mgwirizano. Ngati mungafunike kusintha zisindikizo za valve kapena thupi lonse, mumangomasula mtedza ndikuwutulutsa. Ichi ndi chifukwa chake ife ku Pntek timalimbikitsa kupanga mgwirizano weniweni; imasintha kukonza kwakukulu kukhala ntchito yosavuta ya mphindi 5.
Standard vs. True Union Ball Valve
| Mbali | Mpira Wokhazikika (Wokhazikika) Wovala | True Union Ball Valve |
|---|---|---|
| Kuyika | Zokhazikika (zosungunulira-zosungunulira) | Zothandiza (mtedza wa mgwirizano) |
| Kusamalira | Pamafunika kudula chitoliro | Thupi limachotsa kuti likonze mosavuta |
| Mtengo Woyamba | Pansi | Zapamwamba |
| Mtengo Wanthawi Yaitali | Zotsika (zokonza zodula) | Zapamwamba (zimapulumutsa nthawi ndi ntchito) |
Kodi vavu ya mgwirizano ndi chiyani?
Mukuwona mawu oti "valavu ya mgwirizano" ndikuganiza kuti ndi gulu losiyana, monga valavu yachipata kapena valavu. Kukayikira kumeneku kungakuletseni kusankha njira yothandiza kwambiri.
Valve ya mgwirizano si mtundu wa makina, koma mtundu wa kugwirizana. Ndi valavu iliyonse yomwe imagwiritsa ntchito zopangira mgwirizano (mtedza wa ulusi) kuti ilumikizane ndi thupi la valve ku mapeto a chitoliro, kuti achotse mosavuta.
"Mgwirizano" womwewo ndi gawo laukadaulo laukadaulo. Zili ndi zigawo zazikulu zitatu: tailpieces ziwiri zomwe zimagwirizanitsa ndi chitoliro (mwina ndi zosungunulira zosungunulira kapena ulusi), ndi mtedza wa ulusi womwe umawakoka pamodzi kuti apange chisindikizo. A “valavu ya mgwirizano"Choncho, mutha kukhala ndi valavu yeniyeni ya mpira, valavu yoyang'anira mgwirizano weniweni, kapena valavu yeniyeni ya diaphragm. Cholinga chimakhala chofanana nthawi zonse:utumiki. Zimakulolani kudzipatula ndikuchotsa chida popanda kukhumudwitsa dongosolo lonse kapena, chofunika kwambiri, popanda kudula chitoliro chanu. Njira yokhazikika iyi ndi maziko a mapangidwe amakono, opangira mipope komanso gawo lalikulu la filosofi ya "win-win" yomwe ndimagawana ndi anzanga ngati Budi. Zimapulumutsa makasitomala ake nthawi ndi ndalama pa moyo wa dongosolo.
Kodi mavavu amitundu itatu ndi ati?
Mwakhala mukugwiritsa ntchito mavavu a mpira pachilichonse, koma pulogalamu imodzi imafuna kuwongolera kolondola. Mumayesa kutseka pang'ono valavu ya mpira, koma ndizovuta kuwongolera ndipo mumamva phokoso lachilendo.
Mitundu itatu yayikulu yogwira ntchito ya ma valve ndi Shut-Off (On/Off), Throttling (Regulating), ndi Non-Return (Backflow Prevention). Mtundu uliwonse umapangidwira ntchito yosiyana kwambiri, ndipo kugwiritsa ntchito zolakwika kungawononge dongosolo lanu.
Kudziwa magulu ofunikira ndikofunikira pakusankha chida choyenera pantchitoyo. Kugwiritsa ntchito valavu yolakwika ndiko kulakwitsa kofala kwambiri. Valve ya mpira ndi avalve yotseka; idapangidwa kuti ikhale yotsegula kapena kutsekedwa kwathunthu. Kuyigwiritsa ntchito kuti ichepetse kuthamanga kungayambitse chipwirikiti chomwe chimawononga mpira ndi mipando, zomwe zimapangitsa kuti zilephereke.
Magawo a Vavu Afotokozedwa
| Mtundu wa Vavu | Ntchito Yoyambira | Zitsanzo Zofanana | Ntchito Yabwino Kwambiri |
|---|---|---|---|
| Kuzimitsa (Kuyatsa/Kuzimitsa) | Kuyimitsa kwathunthu kapena kulola kuyenda. | Vavu ya Mpira, Vavu ya Chipata, Vavu ya Gulugufe | Kupatula magawo kapena zida. |
| Kuwongolera (Kuwongolera) | Kuwongolera kuthamanga kapena kuthamanga kwa kuyenda. | Globe Valve, Vavu ya singano | Kukhazikitsa liwiro loyenda bwino. |
| Osabwerera (Backflow) | Kulola kuyenda mbali imodzi yokha. | Onani Vavu, Vavu ya Phazi | Kuteteza mpope ku kubwerera mmbuyo. |
Mitundu 4 ya mavavu a mpira ndi chiyani?
Mumadziwa za ma valve ogwirizana, koma mumawona zosankha zina monga "compact" kapena "chidutswa chimodzi." Simukudziwa chomwe chili chabwino pamapulogalamu osiyanasiyana, ndipo mutha kulipira mochulukira pazinthu zomwe simukuzifuna.
Mitundu inayi ikuluikulu ya ma valve a mpira imasiyanitsidwa ndi mapangidwe a thupi: Chigawo Chimodzi (chosindikizidwa), Chigawo Chachiwiri (Thupi la ulusi), Zigawo Zitatu (monga mgwirizano weniweni), ndi Compact (zosavuta, zopanga ndalama, nthawi zambiri chidutswa chimodzi).
Ngakhale makina amkati ndi ofanana (mpira wozungulira), momwe thupi limapangidwira zimatengera mtengo wake ndi ntchito yake. M'dziko la PVC, timayang'ana kwambiri chidutswa chimodzi / chophatikizika ndi magawo atatu / mgwirizano weniweni.
- Gawo limodzi /Valve ya Mpira wa Compact:Thupi la valve ndi gawo limodzi, losindikizidwa. Izi ndizopanga ndalama zambiri. Ndiwopepuka, yosavuta, komanso yabwino kwa mapulogalamu omwe kukonza sikudetsa nkhawa ndipo mtengo wake ndiye dalaivala wamkulu.
- Mpira Wamitundu iwiri:Thupi limapangidwa ndi tiziduswa tating'ono ting'onoting'ono, tomwe timatsekera mpira ndikusindikiza mkati. Izi zimalola kukonzanso kwina koma nthawi zambiri zimafunika kuzichotsa pamzere. Ndizofala kwambiri m'mavavu azitsulo.
- Zigawo zitatu (True Union) Valve ya Mpira:Ichi ndiye mapangidwe apamwamba. Amakhala ndi zolumikizira ziwiri zomaliza (zolowera) ndi thupi lapakati. Izi zimathandiza kuti thupi lalikulu lichotsedwe kuti likonzedwe kapena kusinthidwa popanda kusokoneza chitoliro. Ichi ndiye chisankho chodalirika komanso chotsika mtengo kwambiri pamapulogalamu ovuta kwambiri kwa nthawi yayitali.
Ku Pntek, timayang'ana kwambiri pakupereka kophatikizana kopambana komansoma valve ogwirizana, kupatsa anzathu ngati Budi zosankha zoyenera pazosowa zilizonse zamakasitomala.
Mapeto
Vavu ya mpira ndi njira; mgwirizano ndi mgwirizano. Valavu yeniyeni ya mpira imawaphatikiza, kupereka kuwongolera kwapamwamba komanso kukonza kosavuta pamakina aliwonse aukadaulo.
