Mwayika valavu yatsopano ya PVC ndipo mukuyembekeza kuti igwire ntchito kwa zaka zambiri. Koma kulephera mwadzidzidzi kungayambitse kusefukira kwa madzi, kuwononga zida, ndikuletsa ntchito.

Valavu ya mpira ya PVC yapamwamba kwambiri imatha kukhala zaka 20 m'malo abwino. Komabe, nthawi yake yeniyeni imadalira zinthu monga kuwala kwa UV, kukhudzana ndi mankhwala, kutentha kwa madzi, kuthamanga kwa makina, komanso kangati komwe imagwiritsidwa ntchito.

Chiwerengero cha zaka 20 chimenecho ndi poyambira, osati chitsimikizo. Yankho lenileni ndi lakuti “zimadalira.” Ndinkalankhula za izi ndi Budi, woyang'anira zogula zomwe ndimagwira naye ntchito ku Indonesia. Amaona zonse. Makasitomala ena ali ndima valve athuimagwira ntchito bwino kwambiri m'machitidwe a ulimi patatha zaka 15. Ena akhala ndi ma valve olephera pasanathe zaka ziwiri. Kusiyana si valavu yokha, koma malo omwe imakhala. Kumvetsetsa zinthu zachilengedwe izi ndiyo njira yokhayo yodziwira nthawi yomwe valavu yanu idzakhalapo ndikuwonetsetsa kuti yafika pamlingo wake wonse.

Kodi valavu ya mpira wa PVC imakhala ndi moyo wautali bwanji?

Mukufuna nambala yosavuta ya dongosolo lanu la polojekiti. Koma kuyika nthawi yanu ndi bajeti yanu pamalingaliro ndi koopsa, makamaka ngati valavu yalephera kale musanayembekezere.

Nthawi ya moyo wa valavu ya mpira wa PVC imayambira pa zaka zingapo mpaka zaka makumi awiri. Izi sizikukhazikika. Nthawi ya moyo imadalira kwathunthu malo omwe imagwira ntchito komanso mtundu wa zipangizo zake.

Ganizirani za moyo wa valavu ngati bajeti. Imayamba ndi zaka 20, ndipo vuto lililonse lovuta "limatha" moyo wake mwachangu. Chomwe chimagwiritsa ntchito kwambiri ndi kuwala kwa dzuwa ndi kugwiritsa ntchito pafupipafupi. Vavu yomwe imatsegulidwa ndi kutsekedwa kambirimbiri patsiku imawononga zisindikizo zake zamkati mwachangu kwambiri kuposa yomwe imazunguliridwa kamodzi pamwezi. Momwemonso, valavu yoyikidwa panja padzuwa lachindunji idzakhala yofooka komanso yofooka pakapita nthawi. Kuwala kwa UV kumaukira ma molekyulu omangira mu PVC. Pakatha zaka zingapo, imatha kukhala yofooka kwambiri kotero kuti kugwedezeka pang'ono kungaiswe. Kugwirizana kwa mankhwala, kutentha kwambiri, ndi kupanikizika kwambiri kumachepetsanso moyo wake. Avalavu yabwinoZopangidwa kuchokera ku PVC yolimba ya 100% yokhala ndi mipando ya PTFE yolimba idzakhala nthawi yayitali kuposa valavu yotsika mtengo yokhala ndi zodzaza, koma ngakhale valavu yabwino kwambiri idzalephera msanga ngati igwiritsidwa ntchito molakwika.

Zinthu Zomwe Zimachepetsa Moyo wa Valve ya PVC

Kodi ma valve a mpira wa PVC ndi odalirika bwanji?

PVC imawoneka ngati pulasitiki, ndipo pulasitiki imatha kuoneka yofooka. Mumada nkhawa kuti ingasweke kapena kutuluka madzi mukapanikizika, makamaka poyerekeza ndi valavu yachitsulo cholemera.

Ma valve apamwamba a PVC ndi odalirika kwambiri pa ntchito zawo. Kapangidwe kawo ka pulasitiki kumatanthauza kuti sakhudzidwa ndi dzimbiri ndi mchere zomwe zimapangitsa kuti ma valve achitsulo alephere kapena kugwidwa pakapita nthawi.

Kudalirika sikungokhudza kuphulika kokha. Kumakhudza ngati valavu imagwira ntchito nthawi yomwe mukuifuna. Budi anandiuza nkhani yokhudza m'modzi mwa makasitomala ake mumakampani opanga nsomba. Ankagwiritsa ntchito mavalavu ampira amkuwa, koma madzi amchere pang'ono adawapangitsa kuti azizire. Patatha chaka chimodzi, mavalavuwo anali olimba kwambiri chifukwa cha dzimbiri kotero kuti sakanatha kuwatembenuza. Anayenera kusinthidwa. Anasintha kupita ku mavalavu athu a mpira wa PVC. Patatha zaka zisanu, mavalavu omwewo a PVC akuzungulira bwino monga momwe adakhalira tsiku lomwe adayikidwa. Uku ndiye kudalirika kwenikweni kwa PVC. Sichita dzimbiri. Sichitsekeka ndi sikelo kapena mchere. Bola ngati ikugwiritsidwa ntchito mkati mwa malire ake opanikizika/kutentha komanso kutetezedwa ku UV, magwiridwe ake sadzachepa. Vavu ya PVC yabwino yokhala ndi yosalalaMipando ya PTFEndi odalirikaMphete za EPDM Oimapereka kudalirika kwa nthawi yayitali komanso kodziwikiratu komwe chitsulo nthawi zambiri sichingafanane nako pakugwiritsa ntchito madzi.

Kodi ma valve a mpira ndi abwino kwa nthawi yayitali bwanji?

Mukuyerekeza valavu ya PVC ndi yamkuwa. Yachitsulo imamveka yolemera, kotero iyenera kukhala yabwinoko, sichoncho? Kuganiza kumeneku kungakupangitseni kusankha valavu yolakwika pa ntchitoyo.

Ma valve a mpira amakhala abwino kwa zaka zambiri akagwiritsidwa ntchito moyenera. Pa PVC, izi zikutanthauza kugwiritsa ntchito madzi ozizira popanda kuwala kwa UV mwachindunji. Pa chitsulo, zikutanthauza madzi oyera, osawononga.Valavu ya PVCnthawi zambiri zimakhalapo kuposavalavu yachitsulom'malo ankhanza.

"Kodi ndi yabwino kwa nthawi yayitali bwanji?" ndi funso loti "Kodi ndi yabwino kwa chiyani?" Valavu yachitsulo chosapanga dzimbiri yapamwamba ndi yabwino kwambiri, koma si yabwino kwa dziwe losambira lomwe lili ndi madzi a chlorine, omwe amatha kuwononga chitsulocho pakapita nthawi. Valavu yamkuwa ndi chisankho chabwino kwambiri, koma imalephera m'makina okhala ndi feteleza kapena madzi a acidic. Apa ndi pomwe PVC imawala. Ndi chisankho chabwino kwambiri pamitundu yambiri yogwiritsira ntchito madzi, kuphatikizapo kuthirira, ulimi wa m'madzi, maiwe, ndi mapaipi wamba. M'malo awa, sichidzawonongeka, kotero chimagwira ntchito bwino kwa zaka zambiri. Ngakhale sichabwino pamadzi otentha kapena kuthamanga kwambiri, ndi chisankho chabwino kwambiri pa malo ake enieni. Valavu ya PVC yogwiritsidwa ntchito moyenera idzakhala "yabwino" kwa nthawi yayitali kuposa valavu yachitsulo yogwiritsidwa ntchito molakwika. Makasitomala opambana kwambiri a Budi ndi omwe amafananiza zinthu za valavu ndi madzi, osati kungoganiza za mphamvu.

Kodi ma valve a mpira amawonongeka?

Valavu yanu yasiya kugwira ntchito. Mukudabwa ngati yangotha ​​kumene kapena ngati pali china chake chomwe chachititsa kuti ilephere. Kudziwa chifukwa chake yalephera ndiye chinsinsi chopewera nthawi ina.

Inde, ma valve a mpira amawonongeka pazifukwa zingapo zomveka bwino. Zovuta kwambiri ndi kusweka kwa zisindikizo chifukwa chogwiritsidwa ntchito pafupipafupi, kuwonongeka kwa UV komwe kumayambitsa kusweka, kuukira kwa mankhwala pazinthu, kapena kuwonongeka kwakuthupi chifukwa cha kugunda kapena kulimba kwambiri.

Ma valve a mpira samangosiya kugwira ntchito chifukwa cha ukalamba; gawo linalake limalephera. Malo ofala kwambiri ndi zisindikizo zamkati. Mipando ya PTFE yomwe imatseka mpira imatha kutha pambuyo pa maulendo ambirimbiri otseguka/kutseka, zomwe zimapangitsa kuti pakhale kutayikira pang'ono. Ma EPDM O-rings pa tsinde amathanso kutha, zomwe zimapangitsa kuti pakhale kutayikira pa chogwirira. Uku ndi kutayikira kwachibadwa. Chifukwa chachiwiri chachikulu ndi kuwonongeka kwa chilengedwe. Monga tafotokozera, kuwala kwa UV ndi koopsa, komwe kumapangitsa kuti thupi la valve likhale lofooka. Mankhwala olakwika amatha kupangitsa PVC kukhala yofewa kapena kuwononga ma O-rings. Njira yachitatu yomwe amawonongeka ndi kuyika molakwika. Cholakwika chomwe ndimawona kwambiri ndi anthu omwe amamangirira ma valve a PVC opangidwa ndi ulusi kwambiri. Amakulunga tepi yochuluka kwambiri ya ulusi kenako amagwiritsa ntchito wrench yayikulu, yomwe imatha kuswa thupi la valve pomwe cholumikiziracho chili. Kumvetsetsa njira zolephera izi kumakuthandizani kuteteza ndalama zanu ndikuwonetsetsa kuti zikugwira ntchito.

Mapeto

Valavu ya PVC yabwino imatha kukhalapo kwa zaka zambiri. Nthawi yake yogwira ntchito imadalira nthawi yochepa koma imadalira kwambiri kugwiritsidwa ntchito moyenera, chitetezo ku kuwala kwa UV, komanso kapangidwe koyenera ka makina ake.
