Nkhani - Momwe mungapangire valavu ya mpira wa PVC kukhala yosavuta?

Vavu imakakamira mwachangu, ndipo matumbo anu amakuuzani kuti mugwire wrench yayikulu. Koma mphamvu zambiri zimatha kuthyola chogwiriracho, kutembenuza ntchito yosavuta kukhala kukonza kwapaipi yayikulu.

Gwiritsani ntchito chida ngati pliers-lock pliers kapena wrench lamba kuti muwonjezere mphamvu, kugwira chogwirira pafupi ndi maziko ake. Kwa valavu yatsopano, izi zidzasweka mu zisindikizo. Kwa valavu yakale, imagonjetsa kuuma kwa kusagwiritsidwa ntchito.

Munthu akugwiritsa ntchito wrench yolumikizira bwino pa chogwirira cha valve ya PVC

Ichi ndi chimodzi mwazinthu zoyamba zomwe ndimawonetsa pophunzitsa mabwenzi atsopano monga Budi ndi gulu lake ku Indonesia. Makasitomala awo, omwe ndi akatswiri opanga makontrakitala, ayenera kukhala ndi chidaliro pazinthu zomwe amayika. Akakumana ndi valavu yatsopano yolimba, ndikufuna kuti awone ngati chizindikiro cha chisindikizo chabwino, osati chilema. Powasonyeza njira yolondola yochitiragwiritsani ntchito mwayipopanda kuwononga, timasintha kusatsimikizika kwawo ndi chidaliro. Luso lothandizali ndi gawo laling'ono koma lofunika kwambiri la mgwirizano wamphamvu, wopambana-wopambana.

Kodi mutha kudzoza valavu ya mpira wa PVC?

Muli ndi valavu yolimba ndipo chibadwa chanu ndikutenga mafuta opopera wamba. Mukukayikira, mukudabwa ngati mankhwalawo angawononge pulasitiki kapena kuipitsa madzi odutsamo.

Inde, mutha, koma muyenera kugwiritsa ntchito mafuta opangira silicon 100%. Osagwiritsa ntchito mafuta opangira mafuta monga WD-40, chifukwa amawononga pulasitiki ya PVC, ndikupangitsa kuti ikhale yolimba ndikupangitsa kuti iwonongeke.

Chitini chamafuta a silicone chokhala ndi cholembera chobiriwira pafupi ndi valavu, ndi chitini cha WD-40 chokhala ndi X wofiira.

Ili ndiye lamulo lofunika kwambiri lachitetezo lomwe ndimaphunzitsa, ndipo ndimaonetsetsa kuti aliyense kuchokera kugulu logula la Budi kupita kwa ogulitsa ake akumvetsetsa. Kuopsa kogwiritsa ntchito mafuta olakwika ndikowona komanso kowopsa. Mafuta opangira mafuta, kuphatikiza mafuta am'nyumba wamba ndi zopopera, amakhala ndi mankhwala otchedwa petroleum distillates. Mankhwalawa amakhala ngati zosungunulira pa pulasitiki ya PVC. Amaphwanya mamolekyu a zinthuzo, ndikupangitsa kuti ikhale yofooka komanso yolimba. Vavu imatha kutembenuka mosavuta kwa tsiku, koma imatha kulephera mowopsa ndikuphulika pakadutsa sabata. Njira yokhayo yotetezeka ndiyo100% mafuta a silicone. Silicone ndi inert yamankhwala, kotero sichingagwirizane ndi thupi la PVC, EPDM O-rings, kapena mipando ya PTFE mkati mwa valve. Pa dongosolo lililonse lonyamula madzi akumwa, ndikofunikira kugwiritsa ntchito mafuta a silicone omwe aliNSF-61 yovomerezeka, kutanthauza kuti ndi yabwino kudyedwa ndi anthu. Izi sizongolimbikitsa; ndizofunikira pachitetezo ndi kudalirika.

Chifukwa chiyani valavu yanga ya PVC imakhala yovuta kutembenuza?

Mwangogula valavu yatsopano ndipo chogwiriracho ndi cholimba modabwitsa. Mumayamba kuda nkhawa kuti ndi chinthu chotsika kwambiri chomwe chidzalephera pomwe mukufunikira kwambiri.

ChatsopanoValve ya mpira wa PVCndizolimba chifukwa zisindikizo zake zamkati zolimba, zopangidwa mwangwiro zimapanga kulumikizana kwabwino kwambiri, kosadukiza. Kukana koyamba kumeneku ndi chizindikiro chabwino cha valve yapamwamba, osati chilema.

Mawonedwe odulidwa a valavu yatsopano ya mpira yomwe ikuwonetsa kukwanira bwino pakati pa mpira ndi mipando yoyera ya PTFE

Ndimakonda kufotokozera izi kwa anzathu chifukwa zimasintha momwe amawonera. Kuuma ndi mawonekedwe, osati chilema. Ku Pntek, cholinga chathu chachikulu ndikupanga ma valve omwe amapereka 100% shutoff yogwira ntchito kwa zaka zambiri. Kuti tichite izi, timagwiritsa ntchito kwambirizolimba kupanga kulolerana. Mkati mwa valavu, mpira wosalala wa PVC umakanikiza awiri atsopanoPTFE (Teflon) mipando. Vavu ikakhala yatsopano, malowa amakhala owuma komanso aukhondo. Kutembenuka koyamba kumafuna mphamvu zambiri kuti mugonjetse kukangana kokhazikika pakati pa magawo olumikizana bwinowa. Zili ngati kutsegula mtsuko watsopano wa kupanikizana - kupotoza koyamba kumakhala kovuta kwambiri chifukwa kumaswa chisindikizo chabwino kwambiri. Vavu yomwe imamveka ngati yomasuka m'bokosiyo imatha kukhala ndi zololera zochepa, zomwe zimatha kuyambitsa kulira. Choncho, chogwirira cholimba chimatanthauza kuti mukugwira valavu yopangidwa bwino, yodalirika. Ngati valavu yakale ikuuma, ndi vuto lina, nthawi zambiri limayamba chifukwa cha kuchuluka kwa mchere mkati.

Momwe mungapangire valavu ya mpira kukhala yosavuta?

Chogwirizira pa valve yanu sichidzagwedezeka ndi dzanja lanu. Chiyeso chogwiritsa ntchito mphamvu yayikulu ndi chida chachikulu ndi champhamvu, koma mukudziwa kuti ndi njira yopangira chogwirira chosweka kapena valavu yosweka.

Yankho lake ndikugwiritsa ntchito nzeru zodziwikiratu, osati mwankhanza. Gwiritsani ntchito chida chonga nsonga kapena pliers pa chogwirira, koma onetsetsani kuti mukugwiritsa ntchito mphamvu pafupi ndi tsinde lapakati la valve momwe mungathere.

Zotsekera zotsekera tchanelo zogwira pansi pa chogwirira cha valve

Ili ndi phunziro mu physics yosavuta yomwe ingapulumutse mavuto ambiri. Kugwiritsa ntchito mphamvu kumapeto kwa chogwirira kumapangitsa kuti pakhale zovuta zambiri pa pulasitiki ndipo ndizomwe zimayambitsa zogwirira ntchito zowonongeka. Cholinga ndikutembenuza tsinde lamkati, osati kupindika chogwirira.

Zida Zoyenera ndi Njira

Wrench Yachingwe:Ichi ndiye chida chabwino kwambiri chogwirira ntchito. Lamba lamphira limagwira chogwiriracho mwamphamvu popanda kukanda kapena kuphwanya pulasitiki. Zimapereka zabwino kwambiri, ngakhale zowonjezera.
Channel-Lock Pliers:Izi ndizofala kwambiri ndipo zimagwira ntchito bwino. Chinsinsi ndikugwira gawo lokhuthala la chogwirira pomwe limalumikizana ndi thupi la valve. Samalani kuti musafinyine kwambiri kuti muphwanye pulasitiki.
Kupanikizika Kwambiri:Osagwiritsa ntchito nkhonya zowomba kapena kusuntha mwachangu. Ikani mwamphamvu, yokhazikika, komanso yolimba. Izi zimapatsa mbali zamkati nthawi yosuntha ndikumasuka.

Langizo lalikulu kwa makontrakitala ndikugwiritsira ntchito chogwirira cha valve yatsopano mmbuyo ndi mtsogolo kangapokalekumamatira mu payipi. Zimakhala zosavuta kuthyola zisindikizo pamene mungathe kugwira valavu mosamala m'manja mwanu.

Momwe mungamasulire valavu yolimba ya mpira?

Muli ndi valavu yakale yomwe yagwidwa kwathunthu. Sizinatembenuzidwe kwa zaka zambiri, ndipo tsopano zikuwoneka ngati zomangidwa ndi simenti. Mukuganiza kuti mudzafunika kudula chitoliro.

Kwa valavu yakale yomata kwambiri, choyamba muzitseka madzi ndikumasula mphamvu. Kenako, yesani kugwiritsa ntchito kutentha pang'ono kuchokera ku chowumitsira tsitsi kupita ku thupi la valve kuti muthandizire kukulitsa mbali ndikuphwanya chomangiracho.

Munthu akuwotha valavu ya mpira wa PVC ndi chowumitsira tsitsi, kupewa kutentha kwambiri

Ngati mwayi wokhawokha sikokwanira, iyi ndi sitepe yotsatira musanayese kusokoneza kapena kusiya ndikuisintha. Mavavu akale nthawi zambiri amakakamira pazifukwa ziwiri:mineral scalekuchokera kumadzi olimba apanga mkati, kapena zisindikizo zamkati zatsatizana ndi mpira kwa nthawi yayitali yosagwira ntchito. Kugwiritsa ntchitokutentha pang'ononthawi zina zimathandiza. Thupi la PVC lidzakula pang'ono kuposa ziwalo zamkati, zomwe zingakhale zokwanira kuthyola mchere wa mchere kapena mgwirizano pakati pa zisindikizo ndi mpira. Ndikofunikira kugwiritsa ntchito chowumitsira tsitsi, osati mfuti kapena tochi. Kutentha kwakukulu kumapotoza kapena kusungunula PVC. Pang'onopang'ono tenthetsani kunja kwa thupi la valve kwa mphindi imodzi kapena ziwiri, kenaka yesani kutembenuza chogwiririranso pogwiritsa ntchito njira yoyenera yothandizira ndi chida. Ngati isuntha, yesani mmbuyo ndi mtsogolo kangapo kuti muchotse makinawo. Ngati ikadali yokakamira, kubwezeretsa ndi njira yanu yokhayo yodalirika.

Mapeto

Kuti ma valve atembenuke mosavuta, gwiritsani ntchito mphamvu yanzeru pamunsi mwa chogwirira. Osagwiritsa ntchito mafuta opangira mafuta - silicone 100% yokha ndiyotetezeka. Kwa mavavu akale, omata, kutentha pang'ono kungathandize.
