Nkhani - Kodi valavu ya mpira wa PVC imagwiritsidwa ntchito pa chiyani?

Mukugwira ntchito pa waya wamadzi ndipo mukufunika valavu. Koma kugwiritsa ntchito mtundu wolakwika kungayambitse dzimbiri, kutayikira madzi, kapena kuwononga ndalama zambiri pa valavu yomwe ingakhale yochuluka kwambiri.

Ma valve a mpira a PVC amagwiritsidwa ntchito makamaka poyang'anira kuyatsa/kutseka m'madzi ozizira komanso m'makina ogwiritsira ntchito madzi. Ntchito zawo zodziwika kwambiri ndi mu ulimi wothirira, maiwe ndi malo osambira, ulimi wa nsomba, ndi mitsinje yamadzi yomwe imagwiritsidwa ntchito nthawi zambiri komwe kukana dzimbiri ndikofunikira.

Vavu ya mpira wa PVC yapamwamba kwambiri yoyikidwa pa chitoliro mu makina othirira

Nthawi zambiri ndimafunsidwa funso ili ndi ogwirizana nawo monga Budi, woyang'anira zogula ku Indonesia. Akamaphunzitsa ogulitsa atsopano, chimodzi mwa zinthu zoyambirira zomwe ayenera kuphunzira sikuti amangobwereza zinthu zomwe amagulitsa, koma kumvetsetsa ntchito ya kasitomala. Kasitomala samangofuna valavu; amafuna kulamulira madzi mosamala komanso modalirika. Vavu ya mpira wa PVC si pulasitiki yokha; ndi mlonda wa pachipata. Kumvetsa komwe imagwiritsidwa ntchito komanso chifukwa chake kumathandiza gulu lake kupereka yankho lenileni, osati kungogulitsa gawo. Zonse ndi zokhudzana ndi kufananiza chida choyenera ndi ntchito yoyenera, ndipo mavavu awa ali ndi ntchito zinazake zomwe amachita bwino kwambiri.

Kodi ma valve a mpira wa PVC amagwiritsidwa ntchito pa chiyani?

Mukuona ma valve a PVC omwe amagwiritsidwa ntchito m'njira iliyonse kuyambira m'mafamu mpaka m'mabwalo a nyumba. Koma n'chiyani chimawapangitsa kukhala chisankho choyenera pantchito izi komanso chisankho cholakwika kwa ena? N'kofunika.

Ma valve a mpira a PVC amagwiritsidwa ntchito makamaka powongolera kuyenda kwa madzi ozizira. Ntchito zazikulu ndi monga kuthirira, mapaipi a dziwe losambira, ulimi wa nsomba, aquaponics, ndi mapaipi ang'onoang'ono amalonda kapena okhala m'nyumba komwe dzimbiri ndi dzimbiri la mankhwala zimadetsa nkhawa.

Chithunzi chosonyeza ma valve a PVC omwe akugwiritsidwa ntchito: munda wothirira, makina opopera dziwe, ndi malo osungiramo madzi a m'nyanja

Tiyeni tiwone komwe ma valve awa amawala.kuthirira, amagwira ntchito ngati zotsekera pa mzere waukulu kapena kuwongolera madera osiyanasiyana othirira. Amakhala pansi pa dothi ndipo nthawi zonse amakhala pamavuto amadzi ndi feteleza, malo omwe angawononge ma valve ambiri achitsulo, koma PVC sikhudzidwa konse.maiwe ndi malo osambiraMadziwo amathiridwa ndi chlorine kapena mchere. PVC ndiye muyezo wa makampani opangira mapampu ndi zosefera chifukwa sichimakhudzidwa ndi dzimbiri la mankhwala. Izi zimagwiranso ntchito pa ulimi wa nsomba, komwe amawongolera kuyenda kwa madzi polima nsomba ndi nkhanu. Pa mapampu wamba, ndi chisankho chabwino kwambiri komanso chotsika mtengo pa mzere uliwonse wa madzi ozizira, monga makina opopera madzi kapena ngati njira yozimitsira madzi, komwe mukusowa njira yodalirika yoletsera kuyenda kwa madziwo chifukwa chokonza kapena pamavuto.

Mapulogalamu Ofala a Ma Valves a Mpira wa PVC

Kugwiritsa ntchito	Chifukwa chiyani PVC ndi chisankho chabwino kwambiri
Kuthirira ndi Ulimi	Chotetezeka ku dzimbiri kuchokera ku dothi, madzi, ndi feteleza.
Maiwe Osambira, Malo Osambira ndi Maiwe Osambira	Sizingawonongeke ndi chlorine, madzi amchere, kapena mankhwala ena.
Ulimi wa Zam'madzi ndi Malo Osungiramo Zam'madzi	Amasamalira bwino kuyenda kwa madzi nthawi zonse popanda kuwononga kapena kutulutsa madzi.
Mapaipi a Madzi Ozizira Ambiri	Imapereka malo odalirika, osachita dzimbiri, komanso otsika mtengo otsekera.

Kodi cholinga cha valavu ya PVC ndi chiyani?

Madzi akuyenda kudzera mu chitoliro, koma mulibe njira yowaletsera. Kulephera kulamulira kumeneku kumapangitsa kuti kukonza kapena kukonza kusakhale kotheka komanso koopsa. Valavu yosavuta imakonza izi.

Cholinga chachikulu cha valavu ya PVC ndikupereka malo odalirika komanso olimba owongolera mu dongosolo lamadzimadzi. Imakupatsani mwayi woyambitsa, kuyimitsa, kapena nthawi zina kuwongolera kayendedwe ka madzi, ndi phindu lalikulu lokhala lolimba ku dzimbiri.

Chithunzi chosavuta chowonetsa valavu ya PVC mu chitoliro, yomwe imaletsa madzi kufika pamutu wa sprinkler

Cholinga chachikulu cha valavu iliyonse ndi kulamulira, ndipo mavalavu a PVC amapereka mtundu winawake wa kulamulira. Cholinga chawo chachikulu ndikudzipatulaTangoganizirani mutu wa sprinkler wasweka m'bwalo mwanu. Popanda valavu, muyenera kutseka madzi m'nyumba yonse kuti mungoikonza. Vavu ya mpira wa PVC yomwe ili pamzerewu imakulolani kuti mulekanitse gawo limenelo, kukonza, ndikuyatsanso. Izi ndizofunikira kwambiri pakukonza kulikonse. Cholinga china ndi ichikusokonezaPogwiritsa ntchito valavu ya mpira ya njira zitatu, mutha kuwongolera madzi kuchokera ku gwero limodzi kupita ku malo awiri osiyana, monga kusinthana pakati pa madera awiri osiyana othirira. Pomaliza, PVC yokha imagwira ntchito:moyo wautaliImagwira ntchito yolamulira madzi popanda dzimbiri kapena kuwononga, kuonetsetsa kuti ikugwira ntchito nthawi iliyonse yomwe mukuifuna, chaka ndi chaka. Ndicho cholinga chake chenicheni: kulamulira kodalirika komwe kumatenga nthawi yayitali.

Kodi cholinga chachikulu cha valavu ya mpira ndi chiyani?

Muyenera kutseka chingwe cha madzi mwachangu komanso motsimikiza. Ma valve ochedwa omwe amafunika kutembenuka kangapo angakupangitseni kudabwa ngati valavuyo yatsekedwadi.

Cholinga chachikulu cha valavu ya mpira ndikupereka mphamvu yofulumira komanso yodalirika yoyatsira/kutseka. Kapangidwe kake kosavuta kozungulira kotala kamodzi kamalola kuti chigwiritsidwe ntchito nthawi yomweyo, ndipo malo ogwirira ntchito amapereka chizindikiro chowonekera bwino cha ngati chatsegulidwa kapena chatsekedwa.

Chithunzi chowonekera bwino chomwe chikuwonetsa chogwirira cha valavu ya mpira chofanana ndi chitoliro (chotseguka) ndi chopingasa (chotsekedwa)

Luso la valavu ya mpira ndi kuphweka kwake. Mkati mwa valavu muli mpira wokhala ndi dzenje lobowoledwa molunjika. Pamene chogwirira chikugwirizana ndi chitoliro, dzenjelo limagwirizana ndi kayendedwe ka madzi, ndipo valavu imatsegulidwa kwathunthu. Mukatembenuza chogwirira madigiri 90, chimakhala cholunjika ku chitoliro. Izi zimazungulira mpirawo kotero kuti gawo lolimba limatseka kayendedwe ka madzi, ndikutseka nthawi yomweyo. Kapangidwe kameneka kamapereka zabwino ziwiri zazikulu zomwe zimafotokoza cholinga chake. Choyamba ndiliwiroMukhoza kusintha kuchoka pa kutseguka kwathunthu mpaka kutsekedwa kwathunthu mu sekondi imodzi. Izi ndizofunikira kwambiri pa kutsekedwa kwadzidzidzi. Chachiwiri ndikumveka bwino. Mutha kudziwa momwe valavu ilili pongoyang'ana chogwirira. Palibe kukayikira. Nthawi zonse ndimauza Budi kuti agulitse izi ngati chitetezo. Ndi valavu ya mpira, mumadziwa bwino ngati madzi ali oyaka kapena ozima.

Kodi pali kusiyana kotani pakati pa valavu ya mpira wa mkuwa ndi valavu ya mpira wa PVC?

Mukufuna valavu ya mpira, koma mukuona ya mkuwa ndi ya PVC. Amaoneka mosiyana kwambiri ndipo ali ndi mitengo yosiyana kwambiri. Kusankha yolakwika kungayambitse kulephera.

Kusiyana kwakukulu kuli mu kapangidwe kake ka zinthu ndi malo abwino ogwiritsira ntchito. PVC ndi yopepuka, yosapsa ndi dzimbiri, ndipo ndi yabwino kwambiri pamadzi ozizira. Mkuwa ndi wolimba kwambiri, umatha kupirira kutentha kwambiri ndi kupanikizika, koma ukhoza kupsa ndi dzimbiri m'mikhalidwe ina.

Kuyerekeza kwa valavu yoyera ya mpira wa PVC ndi valavu yachikasu ya mpira wamkuwa

Ndikafotokozera Budi izi m'malo mwa gulu lake, ndimagawa izi m'magawo anayi akuluakulu. Choyamba ndi ichi:kukana dzimbiriApa, PVC ndiye ngwazi yosatsutsika. Ndi mtundu wa pulasitiki, kotero siingathe kuchita dzimbiri. Mkuwa ndi aloyi yomwe imatha kufooka ndi madzi ena pakapita nthawi. Chachiwiri ndikutentha ndi kupanikizikaApa, mkuwa umapambana mosavuta. Umatha kupirira madzi otentha ndi kupanikizika kwakukulu, pomwe PVC yokhazikika imangogwiritsidwa ntchito pamadzi ozizira (osakwana 60°C / 140°F) ndi kupsinjika kochepa. Chachitatu ndimphamvuMkuwa ndi chitsulo ndipo ndi wolimba kwambiri polimbana ndi kugwedezeka. Simungafune kugwiritsa ntchito PVC popanga mipanda ya gasi yachilengedwe pachifukwa ichi. Chachinayi ndimtengoPVC ndi yopepuka kwambiri komanso yotsika mtengo kwambiri, zomwe zimapangitsa kuti ikhale chisankho chotsika mtengo kwambiri pamapulojekiti akuluakulu. Chisankho choyenera chimadalira ntchito yonse.

PVC vs. Brass: Kusiyana Kwakukulu
