Valavu yagwira ntchito mwachangu, ndipo matumbo anu amakuuzani kuti mugwire wrench yayikulu. Koma mphamvu zambiri zimatha kuthyola chogwiriracho mosavuta, zomwe zimapangitsa ntchito yosavuta kukhala yokonza mapaipi akuluakulu.

Gwiritsani ntchito chida monga cholumikizira cha channel-lock kapena wrench ya lamba kuti mupeze mphamvu, pogwira chogwirira pafupi ndi maziko ake. Pa valavu yatsopano, izi zidzasweka zotsekera. Pa valavu yakale, imagonjetsa kuuma chifukwa chosagwiritsidwa ntchito.

Ichi ndi chimodzi mwa zinthu zoyamba zomwe ndimasonyeza pophunzitsa ogwirizana nawo atsopano monga Budi ndi gulu lake ku Indonesia. Makasitomala awo, omwe ndi akatswiri omanga nyumba, ayenera kukhala ndi chidaliro pa zinthu zomwe amaika. Akakumana ndi valavu yatsopano yolimba, ndikufuna kuti azione ngati chizindikiro cha chisindikizo chabwino, osati cholakwika. Mwa kuwawonetsa njira yoyenera yochitira izigwiritsani ntchito mphamvuPopanda kuwononga, timasintha kusatsimikizika kwawo ndi chidaliro. Luso lothandiza ili ndi gawo laling'ono koma lofunika kwambiri pa mgwirizano wolimba, womwe umapindulitsa onse.

Kodi mungathe kudzola 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 omwe akuyendamo.

Inde, mungathe, koma muyenera kugwiritsa ntchito mafuta odzola okhala ndi silicone 100% okha. Musagwiritse ntchito zinthu zopangidwa ndi mafuta monga WD-40, chifukwa zimawononga pulasitiki ya PVC mwa mankhwala, zomwe zimapangitsa kuti ikhale yofooka ndikupangitsa kuti isweke ikapanikizika.

Ili ndi lamulo lofunika kwambiri la chitetezo lomwe ndimaphunzitsa, ndipo ndikutsimikiza kuti aliyense kuyambira gulu logula la Budi mpaka ogwira ntchito yake yogulitsa akumvetsa. Kuopsa kogwiritsa ntchito mafuta osayenera ndi koopsa komanso koopsa. Mafuta odzola ochokera ku mafuta, kuphatikizapo mafuta wamba apakhomo ndi opopera, ali ndi mankhwala otchedwa petroleum distillates. Mankhwalawa amagwira ntchito ngati zosungunulira pa pulasitiki ya PVC. Amawononga kapangidwe ka mamolekyu a chinthucho, zomwe zimapangitsa kuti chikhale chofooka komanso chofooka. Valavu ikhoza kutembenuka mosavuta kwa tsiku limodzi, koma ikhoza kulephera kwambiri ndikuphulika patatha sabata imodzi. Njira yokhayo yotetezeka ndiMafuta a silicone 100%Silicone ndi yopanda mankhwala, kotero sidzagwirizana ndi thupi la PVC, mphete za EPDM O, kapena mipando ya PTFE mkati mwa valavu. Pa makina aliwonse onyamula madzi akumwa, ndikofunikiranso kugwiritsa ntchito mafuta a silicone omwe ndi abwino.Satifiketi ya NSF-61, zomwe zikutanthauza kuti ndi yotetezeka kugwiritsidwa ntchito ndi anthu. Izi si malangizo okha; ndizofunikira kuti munthu akhale wotetezeka komanso wodalirika.

Nchifukwa chiyani valavu yanga ya mpira ya PVC ndi yovuta kuyitembenuza?

Mwangogula valavu yatsopano ndipo chogwirira chake ndi cholimba modabwitsa. Mukuyamba kuda nkhawa kuti ndi chinthu chotsika mtengo chomwe chingawonongeke nthawi yomweyo mukachifuna kwambiri.

ChatsopanoValavu ya mpira wa PVCndi yolimba chifukwa zomangira zake zolimba komanso zomangidwa bwino mkati mwake zimapanga kulumikizana kwabwino kwambiri komanso kosataya madzi. Kukana koyamba kumeneku ndi chizindikiro chabwino cha valavu yapamwamba, osati chilema.

Ndimakonda kufotokozera izi kwa anzathu chifukwa zimasintha kwambiri momwe amaonera zinthu. Kuuma kwake ndi chinthu chodziwika bwino, osati cholakwika. Ku Pntek, cholinga chathu chachikulu ndikupanga ma valve omwe amapereka kutseka kogwira mtima 100% kwa zaka zambiri. Kuti tikwaniritse izi, timagwiritsa ntchito kwambirikulekerera kolimba kwa kupangaMkati mwa valavu, mpira wosalala wa PVC umakanikiza motsutsana ndi awiri atsopanoMipando ya PTFE (Teflon). Pamene valavu ili yatsopano, malo awa amakhala ouma bwino komanso oyera. Kutembenuka koyamba kumafuna mphamvu zambiri kuti athetse kukangana kosasinthasintha pakati pa zigawo izi zogwirizana bwino. Zili ngati kutsegula mtsuko watsopano wa jamu—kupotoza koyamba nthawi zonse kumakhala kovuta kwambiri chifukwa kumaswa chisindikizo chabwino. Vavu yomwe imamveka yomasuka kunja kwa bokosi ikhoza kukhala ndi zovuta zochepa, zomwe pamapeto pake zingayambitse kutuluka kwa madzi. Chifukwa chake, chogwirira cholimba chimatanthauza kuti muli ndi valavu yopangidwa bwino komanso yodalirika. Ngati valavu yakale ilimba, ndi vuto lina, nthawi zambiri limayamba chifukwa cha mchere wochuluka mkati.

Kodi mungatani kuti valavu ya mpira ikhale yosavuta kutembenuka?

Chogwirira cha valavu yanu sichingasunthike ndi dzanja lanu. Chiyeso chogwiritsa ntchito mphamvu zambiri pogwiritsa ntchito chida chachikulu ndi champhamvu, koma mukudziwa kuti ndi njira yabwino yopangira chogwirira chosweka kapena valavu yosweka.

Yankho lake ndikugwiritsa ntchito mphamvu yanzeru, osati mphamvu yankhanza. Gwiritsani ntchito chida monga wrench ya lamba kapena pliers pa chogwirira, koma onetsetsani kuti mwagwiritsa ntchito mphamvu pafupi ndi tsinde lapakati la valavu momwe mungathere.

Ili ndi phunziro la sayansi yosavuta yomwe ingapulumutse mavuto ambiri. Kugwiritsa ntchito mphamvu kumapeto kwa chogwirira kumabweretsa kupsinjika kwakukulu pa pulasitiki ndipo ndicho chifukwa chofala kwambiri cha zogwirira zosweka. Cholinga chake ndi kutembenuza tsinde lamkati, osati kupindika chogwirira.

Zida ndi Njira Zoyenera

• Chingwe cha Lamba:Ichi ndi chida chabwino kwambiri pa ntchitoyi. Lamba wa rabala amagwira chogwirira mwamphamvu popanda kukanda kapena kuphwanya pulasitiki. Chimapereka mphamvu yabwino komanso yofanana.
• Ma Pliers Otsekera Channel:Izi ndi zofala kwambiri ndipo zimagwira ntchito bwino. Chofunika kwambiri ndikugwira gawo lokhuthala la chogwirira pomwe limalumikizana ndi thupi la valavu. Samalani kuti musapanikize kwambiri mpaka mutasweka pulasitiki.

Kodi mungamasulire bwanji valavu yolimba ya mpira?

Muli ndi valavu yakale yomwe yagwidwa kwathunthu. Siinasinthidwe kwa zaka zambiri, ndipo tsopano ikumva ngati yaikidwa simenti pamalo pake. Mukuganiza kuti muyenera kudula chitolirocho.

Ngati valavu yakale yalowa mkati mwa madzi, choyamba tsekani madziwo ndikutulutsa mphamvu. Kenako, yesani kugwiritsa ntchito kutentha pang'ono kuchokera ku choumitsira tsitsi kupita ku thupi la valavu kuti muthandize kukulitsa ziwalozo ndikuswa mgwirizano.

Ngati mphamvu yokha sikokwanira, iyi ndi sitepe yotsatira musanayese kuichotsa kapena kuisiya ndikuyiyika m'malo mwake. Ma valve akale nthawi zambiri amakakamira pazifukwa ziwiri:muyeso wa mchereKuyika mpirawo m'madzi olimba kwakhazikika mkati, kapena zomangira zamkati zagwira mpirawo kwa nthawi yayitali osagwira ntchito.kutentha pang'onoNthawi zina zingathandize. Thupi la PVC limakula pang'ono kuposa ziwalo zamkati, zomwe zingakhale zokwanira kuswa kutumphuka kwa mineral scale kapena mgwirizano pakati pa zomangira ndi mpira. Ndikofunikira kugwiritsa ntchito chowumitsira tsitsi, osati mfuti yotenthetsera kapena tochi. Kutentha kwambiri kudzapotoza kapena kusungunula PVC. Tenthetsani pang'ono kunja kwa thupi la valavu kwa mphindi imodzi kapena ziwiri, kenako yesani kutembenuza chogwirira kachiwiri pogwiritsa ntchito njira yoyenera yogwiritsira ntchito ndi chida. Ngati chikuyenda, chigwiritseni ntchito mobwerezabwereza kuti muchotse makinawo. Ngati chikadali chomangika, kusinthira ndiye njira yokhayo yodalirika.

Mapeto

Kuti muchepetse kutembenuka kwa valavu, gwiritsani ntchito chowongolera chanzeru pansi pa chogwirira. Musagwiritse ntchito mafuta odzola—silicone yokha ndi yomwe ndi yotetezeka. Pa mavalavu akale, omata, kutentha pang'ono kungathandize.
