Muyenera kulamulira kayendedwe ka madzi mu dongosolo lanu. Koma kusankha mtundu wolakwika wa valavu kungayambitse kutuluka, dzimbiri, kapena valavu yomwe imagwira pamene mukuyifuna kwambiri.

Cholinga chachikulu cha valavu ya mpira wa PVC ndikupereka njira yosavuta, yodalirika, komanso yowononga dzimbiri kuti muyambe kapena kuyimitsa kutuluka kwa madzi ozizira mu payipi ndi kotala-kutembenuka kwa chogwirira.

Ganizirani ngati chosinthira chowunikira madzi. Ntchito yake ndi kukhala kapena kuyatsa kwathunthu. Ntchito yosavuta imeneyi ndi yofunika kwambiri pa ntchito zambiri, kuchokera ku mipope ya pakhomo mpaka ku ulimi waukulu. Nthawi zambiri ndimafotokoza izi kwa anzanga, monga Budi ku Indonesia, chifukwa makasitomala ake amafunika mavavu omwe ndi otsika mtengo komanso odalirika. Sangathe kukwanitsa zolephera zomwe zimabwera chifukwa chogwiritsa ntchito zinthu zolakwika pa ntchitoyi. Ngakhale kuti lingalirolo ndi losavuta, kumvetsetsa komwe ndi chifukwa chake kugwiritsa ntchito valavu ya mpira wa PVC ndikofunika kwambiri pomanga dongosolo lomwe limakhalapo.

Kodi ma valve a PVC amagwiritsidwa ntchito bwanji?

Mukuwona mavavu apulasitiki otsika mtengo koma mukudabwa komwe angagwiritsidwe ntchito. Mukuda nkhawa kuti iwo sali olimba mokwanira kuti agwire ntchito yaikulu, zomwe zimakupangitsani kuti muwononge ndalama zambiri pazitsulo zazitsulo zomwe zingathe kuchita dzimbiri.

PVC mpira mavavu ntchito makamaka ntchito madzi ozizira monga ulimi wothirira, maiwe osambira, aquaculture, ndi kugawa madzi ambiri. Ubwino wawo waukulu ndi chitetezo chokwanira ku dzimbiri ndi dzimbiri lamankhwala kuchokera kumankhwala amadzi.

Kukana kwa PVC ku dzimbirindi mphamvu zake zazikulu. Izi zimapangitsa kukhala chisankho chabwino kwa malo aliwonse omwe madzi ndi mankhwala angawononge zitsulo. Kwa makasitomala a Budi omwe amayendetsa famu ya nsomba, mavavu achitsulo sangasankhe chifukwa madzi amchere amatha kuwononga msanga. Vavu ya PVC, kumbali ina, idzagwira ntchito bwino kwa zaka zambiri. Sizokhudza kukhala njira "yotsika mtengo"; ndi za kukhalazolondolazinthu zogwirira ntchito. Amamangidwa kuti azigwiritsidwa ntchito kwambiri, kavalo wodalirika woyendetsa madzi mu machitidwe omwe kutentha sikudzapitirira 60 ° C (140 ° F).

Mapulogalamu Wamba a PVC Ball Valves

Kodi cholinga chachikulu cha valve ya mpira ndi chiyani?

Mukuwona mitundu yosiyanasiyana ya ma valve monga chipata, globe, ndi ma valve a mpira. Kugwiritsira ntchito yolakwika potseka kungayambitse kugwira ntchito pang'onopang'ono, kutayikira, kapena kuwonongeka kwa valve yokha.

Cholinga chachikulu cha valavu iliyonse ya mpira ndi kukhala valve shutoff. Imagwiritsa ntchito kutembenuka kwa 90-degree kuchoka kutseguka kwathunthu mpaka kutsekedwa kwathunthu, kupereka njira yachangu komanso yodalirika yoyimitsa kutuluka kwathunthu.

Mapangidwe ake ndi osavuta kwambiri. Mkati mwa valavu muli mpira wozungulira wokhala ndi dzenje, kapena kubowola, kudutsa pakati. Pamene chogwiriracho chikufanana ndi chitoliro, dzenjelo limagwirizana, kulola kuti madzi adutse popanda malire. Mukatembenuza chogwirira cha madigiri 90, gawo lolimba la mpira limatchinga njira, kuyimitsa kutuluka nthawi yomweyo ndikupanga chisindikizo cholimba. Chochita chofulumirachi ndi chosiyana ndi valavu yachipata, yomwe imafuna kutembenuka kochuluka kuti itseke ndipo imachedwa kwambiri. Zimasiyananso ndi valavu yapadziko lonse, yomwe imapangidwa kuti iziwongolera kapena kutulutsa mpweya. Avalavu ya mpiraidapangidwa kuti itseke. Kuigwiritsa ntchito pamalo otseguka theka kwa nthawi yayitali kungapangitse mipandoyo kuvala mosagwirizana, zomwe pamapeto pake zimatha kutayira zitatsekedwa kwathunthu.

Kodi valve ya PVC imagwiritsidwa ntchito bwanji?

Mumadziwa kuti muyenera kuwongolera madzi, koma mumangodziwa za mavavu a mpira. Mwina mukusowa njira yabwino yothetsera vuto linalake, monga kuteteza madzi kuti asabwerere chakumbuyo.

Vavu ya PVC ndi mawu wamba pa valavu iliyonse yopangidwa kuchokera ku pulasitiki ya PVC. Amagwiritsidwa ntchito kuwongolera, kuwongolera, kapena kuwongolera kutuluka kwamadzimadzi, ndi mitundu yosiyanasiyana yomwe ilipo kuti igwire ntchito zosiyanasiyana monga kutsekereza kapena kuletsa kubwerera.

Ngakhale kuti valavu ya mpira ndi mtundu wofala kwambiri, si ngwazi yokhayo m'banja la PVC. PVC ndi zinthu zosunthika zomwe zimagwiritsidwa ntchito popanga mavavu osiyanasiyana, iliyonse ili ndi ntchito yapadera. Kuganiza kuti mumangofunika valavu ya mpira kuli ngati kuganiza kuti nyundo ndiyo chida chokhacho chomwe mumafunikira mubokosi la zida. Monga opanga, ife ku Pntek timapanga mitundu yosiyanasiyana yaMavavu a PVCchifukwa makasitomala athu ali ndi mavuto osiyanasiyana oti athetse. Makasitomala a Budi omwe amayika mapampu, mwachitsanzo, amafunikira zambiri kuposa kungoyatsa / kuzimitsa; amafunikira chitetezo chodziwikiratu pazida zawo. Kumvetsetsa mitundu yosiyanasiyana kumakuthandizani kusankha chida chabwino kwambiri pagawo lililonse la mapaipi anu.

Mitundu Yodziwika Yama Vavu a PVC ndi Ntchito Zawo

Kodi ntchito ya valve yowunikira mpira mu chitoliro cha PVC ndi chiyani?

Pampu yanu imavutika kuti iyambe kapena imapanga phokoso lokhazikika pamene ikuzima. Izi ndichifukwa choti madzi akuyenda chammbuyo kudzera mu dongosolo, zomwe zimatha kuwononga mpope pakapita nthawi.

Ntchito ya valavu yoyang'ana mpira ndikudziletsa kuti zibwerere. Amalola madzi kuyenda mbali imodzi koma amagwiritsa ntchito mpira wamkati kuti asindikize chitoliro ngati kutuluka kwayima kapena kutembenuka.

Vavu iyi ndi yomwe imakutetezani mwakachetechete. Si valavu ya mpira yomwe mumagwiritsa ntchito ndi chogwirira. Ndi "check valve" yomwe imagwiritsa ntchito mpira ngati njira yake yotseka. Pamene mpope wanu umakankhira madzi patsogolo, kupanikizika kumakweza mpira kuchokera pampando wake, kulola madzi kudutsa. Nthawi yomwe mpopeyo imatseka, kuthamanga kwa madzi kumbali inayo, pamodzi ndi mphamvu yokoka, nthawi yomweyo amakankhira mpirawo pampando wake. Izi zimapanga chisindikizo chomwe chimalepheretsa madzi kutsika pansi pa chitoliro. Ntchito yosavuta iyi ndiyofunikira. Imasunga mpope wanu wokhazikika (yodzaza ndi madzi ndikukonzekera kupita), imalepheretsa mpope kuti zisazungulira chammbuyo (zomwe zingayambitse kuwonongeka), ndikuyimitsa.nyundo yamadzi, chiwopsezo chowononga chobwera chifukwa cha kusintha kwadzidzidzi.

Mapeto

Valavu ya mpira wa PVC imapereka njira yosavuta yowongolera / kutseka madzi ozizira. Kumvetsetsa cholinga chake, ndi maudindo a ma valve ena a PVC, zimatsimikizira kuti mumamanga dongosolo logwira mtima komanso lodalirika.
