Mukuvutika kudalira ma valve a mpira a PVC pama projekiti anu? Kulephera kumodzi kumatha kuwononga ndalama zambiri komanso kuchedwa. Kumvetsetsa kudalirika kwawo ndikofunikira kuti mupange chisankho chogula molimba mtima.

Inde, ma valve a mpira a PVC ndi odalirika kwambiri pazomwe akufuna, makamaka m'madzi ndi ulimi wothirira. Kudalirika kwawo kumachokera ku mapangidwe osavuta, koma kumadalira kwambiri kuwagwiritsa ntchito mkati mwa kukakamiza kwawo kolondola ndi kutentha, kuyika bwino, ndi kusankha wopanga khalidwe.

M'zaka zanga zokhala ndi kampani yopanga nkhungu ndi malonda, ndakhala ndikukambirana zambiri za kudalirika kwazinthu. Nthawi zambiri ndimaganizira za Budi, yemwe ndi woyang'anira kugula kuchokera ku kampani ina yayikulu ku Indonesia. Iye anali ndi udindo wopeza mavavu a PVC ochuluka kwambiri, ndipo nkhawa yake yaikulu inali yakuti: “Kimmy, kodi ndingakhulupirire zimenezi? Anafunikira zambiri kuposa kungoyankha kuti inde kapena ayi. Ayenera kumvetsetsa "chifukwa" ndi "momwe" kumbuyo kwa ntchito yawo kuti ateteze bizinesi yake ndi makasitomala ake. Nkhaniyi ikufotokoza ndendende zimene ndinamuuza, kotero inu mukhoza kupeza molimba mtima.

Kodi mavavu a mpira a PVC ndi odalirika bwanji?

Mumamva nkhani zotsutsana za magwiridwe antchito a valve ya PVC. Kusankha valavu yotengera mtengo wokha kungayambitse kulephera msanga komanso kukonzanso kokwera mtengo. Dziwani malire awo enieni kuti mutsimikizire kuchita bwino.

Mavavu a mpira a PVC ndi odalirika kwambiri akagwiritsidwa ntchito moyenera. Amagwira bwino kwambiri pansi pa 150 PSI ndi 140 ° F (60 ° C). Mapangidwe awo osavuta amawapangitsa kukhala olimba pantchito ngati madzi, koma sakuyenera kutengera madzi otentha kwambiri, zinthu zowononga, kapena mankhwala ena owopsa omwe angawononge PVC.

Budi atandifunsa za kudalirika, ndinamuuza kuti aganizire ngati kusankha chida choyenera pa ntchitoyo. Simungagwiritse ntchito screwdriver kuti mukhomere msomali. Mofananamo, aKudalirika kwa valve ya PVCndizabwino kwambiri, koma mkati mwa zenera lomwe lapangidwa. Zigawo zazikuluzikulu zimagwirira ntchito limodzi kuti zipereke ntchitoyi. Thupi la PVC limapereka kukhulupirika kwadongosolo komanso kukana dzimbiri, pomwe zisindikizo zamkati, zomwe zimapangidwa kuchokeraPTFE (Teflon), onetsetsani kutseka kolimba. Tsinde la O-mphete, kawirikawiriEPDM kapena Viton (FKM), kuteteza kutayikira kuchokera kumalo ogwirira ntchito. Mukasankha valavu kuchokera kwa wopanga olemekezeka, zipangizozi ndi zapamwamba kwambiri ndipo zimakwaniritsa miyezo yapadziko lonse monga ASTM, yomwe imatsimikizira kuti ntchito inayake ikuchitika. Ndi kuphatikiza kophweka ndi zipangizo zabwino zomwe zimawapangitsa kukhala odalirika ogwira ntchito m'mafakitale ambiri.

Zinthu Zakuthupi ndi Zopangira

Kudalirika kumayamba ndi zipangizo. PVC (Polyvinyl Chloride) mwachilengedwe imalimbana ndi dzimbiri kuchokera kumadzi, mchere, ndi ma acid ambiri ndi maziko. Mpira mkati mwake umazungulira bwino motsutsana ndi mipando ya PTFE, chinthu chomwe chimadziwika chifukwa cha kukangana kochepa. Izi zikutanthawuza kuchepa pang'ono ndi kung'ambika pa zikwizikwi.

Malire Ogwirira Ntchito Ndi Ofunikira

Zolephera zambiri zomwe ndaziwona zikuchitika pamene valavu imakankhidwa kupyola malire ake. Kuthamanga kwakukulu kungathe kutsindika thupi la valve, pamene kutentha kwapamwamba kumatha kufewetsa PVC, kupangitsa kuti iwonongeke ndi kutayikira. Nthawi zonse fufuzani zomwe wopanga amasindikiza pa thupi la valve.

Kuyerekeza Kudalirika

Kodi ubwino wa valve ya PVC ndi yotani?

Mufunika valve yotsika mtengo kuti mugule zambiri. Koma mumadandaula kuti mtengo wotsika umatanthauza khalidwe lochepa. Chowonadi ndi chakuti, mavavu a PVC amapereka kuphatikiza kwamphamvu kwabwino.

Ubwino waukulu wa valavu ya mpira wa PVC ndi mtengo wake wotsika, kukana kwa dzimbiri, komanso kupanga kopepuka. Ndiwosavuta kwambiri kukhazikitsa ndikugwiritsa ntchito chowongolera chosavuta cha kotala, kuwapangitsa kukhala osankhidwa bwino komanso osasamalidwa bwino pamapulogalamu ambiri owongolera madzimadzi.

Kwa manejala ogula ngati Budi, zabwino izi zimathana ndi zovuta zake zazikulu:kupititsa patsogolo lusondikusamalira ndalama. Akamayika ma valve pama projekiti masauzande ambiri, kuchokera ku mipope yaing'ono yokhalamo mpaka kuthirira kwakukulu kwaulimi, phindu laZithunzi za PVCkukhala omveka bwino. Mtengo wotsika umamupangitsa kukhala wopikisana kwambiri, pomwe kudalirika komwe ndatchula poyamba kumatsimikizira kuti sakuchita ndi madandaulo nthawi zonse kapena kubwerera. Kwa zaka zambiri, ndawonapo makasitomala monga Budi akuthandiza makasitomala awo, makontrakitala, kusunga nthawi ndi ndalama zambiri pa ntchito pongosintha PVC ngati kuli koyenera. Zopindulitsa zimapitirira kuposa mtengo wogula woyamba; amakhudza njira yonse yogulitsira, kuyambira pakumanga ndi kusungirako katundu mpaka kuyika komaliza. Ndi chisankho chanzeru chomwe chimapereka phindu pamagawo onse.

Mtengo-Kuchita bwino

Uwu ndiye mwayi wowonekera kwambiri. Kwa kukula komweko, valavu ya mpira wa PVC ikhoza kukhala kachigawo kakang'ono ka mtengo wazitsulo zamkuwa kapena zitsulo zosapanga dzimbiri. Kwa Budi, kugula mochulukira kumatanthauza kuti ndalamazo ndi zazikulu. Izi zimalola kampani yake kupereka mitengo yampikisano kwa makontrakitala ndi ogulitsa, kuwathandiza kukulitsa malonda.

Superior Corrosion Resistance

M’nyengo yachinyontho ngati ya ku Indonesia, mavavu achitsulo amatha kuchita dzimbiri. PVC imatetezedwa ku dzimbiri komanso kugonjetsedwa ndi mankhwala osiyanasiyana. Izi zikutanthauza moyo wautali wautumiki komanso kufunikira kocheperako, kuchepetsa mtengo wanthawi yayitali ndikuwonetsetsa kuti dongosololi likuyenda bwino.

Kuyika Kosavuta ndi Kuchita

Kodi mavavu a PVC amalephera?

Mukuda nkhawa ndi kuthekera kwa kulephera kwadzidzidzi, koopsa kwa valve. Vavu imodzi yoyipa imatha kuyimitsa ntchito yonse. Mungapewe zimenezi mwa kumvetsa chifukwa chake amalephera komanso mmene amalepherera.

Inde, mavavu a mpira a PVC amatha ndipo amalephera. Komabe, zolephera nthawi zambiri zimayamba chifukwa cha zinthu zakunja, osati chilema mu valve yokha. Zifukwa zofala kwambiri ndi kuwonongeka kwa thupi, kugwiritsa ntchito valavu kunja kwa kukakamizidwa kapena kutentha kwake, kusagwirizana kwa mankhwala, ndi kuwonongeka kwa UV.

Nthawi ina ndinagwira ntchito ndi kasitomala pa ntchito yaikulu ya ulimi wothirira yemwe anakumana ndi zolephera zingapo. Iye anakhumudwa, kuganiza kuti wagula gulu loipa la mavavu. Nditapita pamalowa, ndidapeza kuti vuto silinali mavavu, koma kukhazikitsa. Ogwira ntchitowa ankagwiritsa ntchito ma wrenches akuluakulu ndikumangitsa ma valve opangidwa ndi ulusi mwamphamvu kwambiri, zomwe zimapangitsa kuti tsitsi likhale losweka m'matupi a valve. Ming'alu yaying'ono iyi imatha kukhazikika kwakanthawi koma ikatha milungu ingapo pambuyo pa kupanikizika koyenera. Popereka maphunziro osavuta olimbitsa manja kuphatikiza kotala, tinathetsa vutoli kwathunthu. Izi zinandiphunzitsa phunziro lofunika kwambiri: kulephera nthawi zambiri kumakhala chizindikiro cha vuto lomwe lingapewedwe. Kwa Budi, kupereka chidziwitso chamtunduwu kwa makasitomala ake kunakhala njira yowonjezerapo phindu ndikumanga kukhulupirika.

Zolakwika Zathupi ndi Kuyika

Ichi ndiye chifukwa choyamba chakulephera chomwe ndikuwona. Kumangitsa kwambiri maulalo a ulusi ndi kulakwitsa kwachikale. Chinanso sichilola kuthandizira koyenera kwa mapaipi, zomwe zimayika kupsinjika pa valve. Kuzizira ndi mdani wamkulu; madzi amakula akamaundana, ndipo amatha kusweka mosavuta valavu ya PVC kuchokera mkati.

Kuwonongeka kwa Zinthu Zakuthupi

Seal and Component Wear

Ngakhale zimakhala zolimba, zosindikizira zamkati zimatha kutha pambuyo pa masauzande ambiri, ngakhale izi ndizosowa m'magwiritsidwe ambiri. Nthawi zambiri, zinyalala ngati mchenga kapena grit zimalowa mu mzere ndikukanda mipando ya PTFE kapena mpirawo. Izi zimapanga njira yoti madzi adutse ngakhale valve itatsekedwa. Sefa yosavuta kumtunda ingalepheretse kulephera kwamtunduwu.

Nchiyani chimapangitsa kuti valavu ya mpira wa PVC itsike?

Kudontha pang'onopang'ono kuchokera ku valve ndi vuto lofala koma lalikulu. Kutayikira kwakung'ono kumeneko kungayambitse kuwonongeka kwa madzi, kutayika kwa mankhwala, ndi zoopsa za chitetezo. Kufotokozera chifukwa chake ndikofunikira.

Kutaya kwa ma valve a mpira a PVC nthawi zambiri kumayambitsidwa ndi chimodzi mwa zinthu zitatu: zisindikizo zamkati zowonongeka (O-mphete kapena mipando), kuyika kosayenera komwe kumatsogolera ku kugwirizana koipa, kapena kuphulika mu thupi la valve lokha. Zinyalala mkati mwa valavu zimathanso kuteteza kuti zisatseke mokwanira.

Wogula akanena kuti zatsikitsa, ndimamufunsa nthawi zonse kuti adziwe komwe zikuchokera. Malo omwe akudontha amakuuzani zonse. Kodi ndikudontha kuchokera pomwe chogwirira chimalowera m'thupi? Ndizo zachikaletsinde la O-ring vuto. Kodi ndikutuluka komwe valavu imalumikizana ndi chitoliro? Izi zikuloza ku cholakwika chokhazikitsa. Kapena madzi akuyendabe pamene valve yatsekedwa? Izi zikutanthauza kuti chisindikizo chamkati chasokonezedwa. Kumvetsetsa izi zosiyanasiyanakutayikira mfundondizofunikira pakuthetsa mavuto. Kwa gulu la Budi, kutha kufunsa mafunsowa kumawathandiza kupereka chithandizo chabwino chamakasitomala, kuzindikira mwachangu ngati ndi vuto lazinthu (zosowa kwambiri) kapena kukhazikitsa kapena kugwiritsa ntchito (zofala kwambiri).

Kutuluka kwa Valve Stem

Tsinde ndi tsinde lomwe limagwirizanitsa chogwirira ndi mpira. Imasindikizidwa ndi mphete imodzi kapena ziwiri za O. M'kupita kwa nthawi, kapena kukhudzana ndi mankhwala osagwirizana, ma O-ringingwa amatha kusokoneza ndikutaya mphamvu zawo zosindikizira, zomwe zimapangitsa kuti pang'onopang'ono kudonthe kuchokera kuzungulira chogwiriracho. Pa mavavu ena amtundu wa "mgwirizano weniweni", mtedza wonyamula tsinde ukhoza kumangidwa kuti upanikizike mphete za O ndikuletsa kudontha kwakung'ono.

Kutuluka pa Malumikizidwe

Izi ndizokhudza kukhazikitsa. Pa zolumikizira zosungunulira (zomatira), kudontha kumachitika ngati simenti yolakwika idagwiritsidwa ntchito, ngati chitoliro ndi zokokera sizinayeretsedwe bwino, kapena ngati simentiyo sinapatsidwe nthawi yokwanira yochiza isanayambe kukakamiza chingwe. Pamalumikizidwe a ulusi, kudontha kumachitika chifukwa cholimba pang'ono, kumangika kwambiri (komwe kumayambitsa ming'alu), kapena kusagwiritsa ntchito tepi yokwanira ya PTFE kusindikiza ulusi.

Kutayikira Kudutsa Chisindikizo Champira

Mapeto

Mwachidule, mavavu a mpira a PVC amapereka kudalirika kwapadera komanso mtengo wake akagwiritsidwa ntchito moyenera. Kumvetsetsa malire awo ndikuwonetsetsa kuti kukhazikitsidwa koyenera ndi makiyi ogwiritsira ntchito mphamvu zawo zonse.
