Kusokonezedwa ndi mitundu yosiyanasiyana ya ma valve? Kusankha yolakwika kungatanthauze kuti muyenera kudula valavu yabwino kwambiri papaipi kuti mukonze kachisindikizo kakang'ono, kotha.

Valavu yamagulu awiri ndi njira yodziwika bwino yopangidwa kuchokera ku zigawo ziwiri zazikulu za thupi zomwe zimalumikizana. Kumanga kumeneku kumangirira mpira ndikusindikiza mkati, koma kumapangitsa kuti valavu iwonongeke kuti ikonzedwe mwa kumasula thupi.

Nkhani yeniyeniyi inabwera pokambirana ndi Budi, woyang'anira zogula yemwe ndimagwira naye ntchito ku Indonesia. Anali ndi kasitomala yemwe anali wokhumudwa chifukwa valavu mumzere wothirira wovuta kwambiri inayamba kutuluka. Vavu inali yotsika mtengo, yachitsanzo chimodzi. Ngakhale kuti vutolo linali kasindikizo kakang’ono chabe ka mkati, sanachitire mwina koma kutseka chilichonse, kudula valavu yonse m’chitolirocho, ndi kumata china chatsopano. Zinasintha kulephera kwa magawo a madola asanu kukhala ntchito yokonza ya theka la tsiku. Chochitika chimenecho chinamuwonetsa nthawi yomweyo mtengo weniweni wa avalavu yokonza, zomwe zinatitsogolera ife molunjika ku zokambirana za mapangidwe awiri.

Kodi pali kusiyana kotani pakati pa 1 piece ndi 2 piece mavavu a mpira?

Mukuwona ma valve awiri omwe amawoneka ofanana, koma imodzi imawononga ndalama zochepa. Kusankha yotsika mtengo kungawoneke ngati kwanzeru, koma kungakuwonongerani ndalama zambiri ngati sikulephera.

Vavu ya mpira wa 1-piece ili ndi thupi limodzi, lolimba ndipo limatha kutaya; sichikhoza kutsegulidwa kuti chikonzedwe. A2-chidutswa valveali ndi thupi lopangidwa ndi ulusi lomwe limalola kuti lichotsedwe, kotero mutha kusintha ziwalo zamkati monga mipando ndi zisindikizo.

Kusiyanitsa kwakukulu ndi serviceability. A1-chidutswa valveamapangidwa kuchokera ku chinthu chimodzi chokha. Mpira ndi mipando imayikidwa mkati mwa imodzi mwa malekezero asanayambe kugwirizana kwa chitoliro. Izi zimapangitsa kuti ikhale yotsika mtengo komanso yamphamvu, yopanda zisindikizo zapathupi zomwe zimatayikira. Koma ikamangidwa, imasindikizidwa mpaka kalekale. Ngati mpando wamkati ukutha chifukwa cha grit kapena kugwiritsidwa ntchito, valavu yonseyo ndi zinyalala. A2-chidutswa valveimadula pang'ono chifukwa ili ndi njira zambiri zopangira. Thupi limapangidwa m'magawo awiri omwe amalumikizana. Izi zimatithandizira kusonkhanitsa ndi mpira ndi mipando mkati. Chofunika kwambiri, chimakulolani kuti muthe kusokoneza pambuyo pake. Pa ntchito iliyonse yomwe kulephera kungayambitse mutu waukulu, kukhoza kukonza valve ya 2-piece kumapangitsa kukhala chisankho chapamwamba kwambiri.

1-Chigawo vs. 2-Piece At-a-Glance

Kodi valve yazigawo ziwiri ndi chiyani?

Mukumva mawu oti "valavu yazidutswa ziwiri" koma izi zikutanthauza chiyani kwenikweni? Kusamvetsetsa chisankho choyambira ichi kungakupangitseni kugula valavu yomwe siili yoyenera pazosowa zanu.

Valavu yokhala ndi zigawo ziwiri imangokhala valavu yomwe thupi lake limapangidwa kuchokera ku zigawo ziwiri zazikulu zomwe zimalumikizidwa palimodzi, nthawi zambiri zimakhala ndi ulusi wolumikizira. Kapangidwe kameneka kamapereka chiwongolero chachikulu pakati pa mtengo wopangira komanso kuthekera kogwiritsa ntchito zida zamkati za valve.

Ganizirani izi ngati mulingo wamakampani wokonzanso, valavu ya mpira wamba. Mapangidwewo ndi kunyengerera. Imadzetsa njira yotha kutayikira pomwe zidutswa ziwiri za thupi zimalumikizana, zomwe valavu ya chidutswa chimodzi imapewa. Komabe, mgwirizanowu umatetezedwa ndi chisindikizo cholimba cha thupi ndipo ndi odalirika kwambiri. Phindu lalikulu lomwe izi zimapanga ndi mwayi. Mwa kumasula mfundo imeneyi, mukhoza kupita ku “matumbo” a valve—mpira ndi mipando iwiri yozungulira imene imamatira. Makasitomala a Budi atakumana ndi zokhumudwitsazi, adaganiza zosunga ma valve athu a zidutswa ziwiri. Amauza makasitomala ake kuti pamtengo wowonjezera pang'ono, akugula inshuwalansi. Ngati mpando ulephera, amatha kugula chosavutakukonza zidakwa madola angapo ndikukonza valavu, m'malo molipira plumber kuti asinthe chinthu chonsecho.

Kodi valavu iwiri ya mpira ndi chiyani?

Kodi munayamba mwamvapo mawu akuti "valvu ya mpira iwiri"? Kugwiritsa ntchito mayina olakwika kungayambitse chisokonezo ndi kuyitanitsa magawo olakwika, kuchititsa kuchedwa kwa polojekiti komanso kuwononga ndalama.

"Vavu iwiri ya mpira" si nthawi yodziwika bwino yamakampani ndipo nthawi zambiri amatchula molakwika "valavu yamitundu iwiri.” Pazochitika zenizeni zogwiritsira ntchito, zingatanthauzenso valavu yachiwiri ya mpira, yomwe ndi valavu yapadera yokhala ndi mipira iwiri mkati mwa thupi limodzi lachitetezo chapamwamba.

Chisokonezochi chimabwera nthawi zina, ndipo ndikofunikira kumveketsa. Makumi asanu ndi anayi mphambu asanu ndi anayi pa zana aliwonse a nthawi, pamene wina apempha "valvu ya mpira iwiri," akukamba zavalavu yamitundu iwiri, ponena za kamangidwe ka thupi komwe takhala tikukambitsirana. Komabe, pali chinthu chochepa kwambiri chomwe chimatchedwa avalavu ya mpira iwiri. Ichi ndi gulu limodzi, lalikulu la vavu lomwe lili ndi magulu awiri osiyana a mpira ndi mpando mkati mwake. Mapangidwe awa amagwiritsidwa ntchito pazinthu zovuta (nthawi zambiri m'makampani amafuta ndi gasi) pomwe mumafunika "kutsekereza kawiri ndi kukhetsa magazi." Izi zikutanthauza kuti mutha kutseka ma valve onse ndikutsegula kukhetsa pang'ono pakati pawo kuti mutsimikizire kuti kutsekedwa kwathunthu, 100% kotsimikizira kutayikira. Pazinthu zamtundu wa PVC monga mipope ndi ulimi wothirira, simudzakumananso ndi valavu iwiri ya mpira. Mawu omwe muyenera kudziwa ndi "zigawo ziwiri."

Kuthetsa Terminology

Kodi mitundu itatu ya mavavu a mpira ndi iti?

Mwaphunzira za 1-piece ndi 2-piece mavavu. Koma bwanji ngati mukufuna kukonza popanda kutseka dongosolo lonse kwa maola? Pali mtundu wachitatu wa izo ndendende.

Mitundu itatu ikuluikulu ya mavavu a mpira, yogawidwa pomanga thupi, ndi 1-chidutswa, 2-chidutswa, ndi 3-chidutswa. Amayimira sikelo kuchokera pamtengo wotsika kwambiri komanso osakonzanso (chidutswa chimodzi) kupita kumtengo wokwera kwambiri komanso kugwiritsa ntchito kosavuta (zidutswa zitatu).

Takambirana ziwiri zoyambirira, kotero tiyeni timalize chithunzicho ndi mtundu wachitatu. A3-piece mpira valvendi umafunika, mosavuta serviced kapangidwe. Zili ndi gawo lapakati la thupi (lomwe limagwira mpira ndi mipando) ndi zipewa ziwiri zosiyana zomwe zimagwirizanitsidwa ndi chitoliro. Zigawo zitatuzi zimagwiridwa pamodzi ndi mabawuti aatali. Matsenga apangidwe awa ndikuti mutha kusiya zipewa zomangika ku chitoliro ndikungomasula thupi lalikulu. Chigawo chapakati ndiye "chimatuluka," kukupatsani mwayi wokwanira wokonzanso popanda kudula chitoliro. Izi ndizofunika kwambiri m'mafakitale kapena malo azamalonda komwe nthawi yocheperako ndiyokwera mtengo kwambiri. Zimalola kutiyachangu zotheka kukonza. Budi tsopano amapereka mitundu yonse itatu kwa makasitomala ake, kuwatsogolera ku chisankho choyenera malinga ndi bajeti yawo komanso momwe ntchito yawo ilili yovuta.

Kuyerekeza kwa 1, 2, ndi 3-Piece Ball Valves

Avalavu yamitundu iwiriamapereka kukonzanso pokhala ndi thupi lomwe limamasula. Ndi malo osangalatsa apakati pakati pa 1-chidutswa chotayidwa ndi mitundu itatu ya mavavu opezeka pamzere.
