Nkhani - Momwe mungayikitsire valavu ya mpira pa chitoliro cha PVC?

Mwaduladula, koma chisindikizo chotsikirapo chimatanthawuza kutaya nthawi, ndalama, ndi zipangizo. Cholowa chimodzi choipa pa mzere wa PVC ukhoza kukukakamizani kudula gawo lonse ndikuyambanso.

Kuyika valavu ya mpira pa chitoliro cha PVC, mumagwiritsa ntchito kuwotcherera kwa zosungunulira. Izi zimaphatikizapo kudula chitoliro mwaukhondo, kuchotsa, kugwiritsa ntchito pulayimale ya PVC ndi simenti pamalo onse awiri, kenako ndikukankhira pamodzi ndi kotala ndikugwira mwamphamvu mpaka chomangira cha mankhwala chikhazikike.

Katswiri wogwiritsa ntchito simenti ya PVC molondola pachitoliro asanayike valavu ya mpira wa Pntek

Uku sikuti kumangomatira; ndi njira yamankhwala yomwe imaphatikiza pulasitiki kukhala chidutswa chimodzi cholimba. Kuchita bwino sikungakambirane kwa ochita bwino. Ndizofunikira kuti nthawi zonse ndizikhala ndi zibwenzi ngati Budi ku Indonesia. Makasitomala ake, kaya ndi makontrakitala akuluakulu kapena ogulitsa m'deralo, amadalira kudalirika. Mgwirizano wolephera sikungotuluka; ndikuchedwa kwa polojekiti komanso kuwononga mbiri yawo. Tiyeni tiyankhe mafunso ofunikira kuti kukhazikitsa kulikonse kukhale kopambana.

Kodi mungalumikizane bwanji valavu ndi chitoliro cha PVC?

Muli ndi valavu m'manja, koma mukuyang'ana chitoliro chosalala. Mukudziwa kuti pali mitundu yosiyanasiyana yolumikizirana, koma ndi iti yomwe ili yoyenera kwa ntchito yanu kuti ikutsimikizireni dongosolo lolimba, lopanda kutayikira?

Mumalumikiza valavu ku chitoliro cha PVC m'njira ziwiri: cholumikizira chosungunulira (socket) chokhazikika, chomwe chili chabwino kwambiri kwa PVC-to-PVC, kapena kulumikizana kwa ulusi, komwe kuli koyenera kujowina PVC ku zigawo zachitsulo monga mapampu.

Kuyerekeza mbali ndi mbali kwa socket (solvent weld) ndi kulumikizana kwa PVC kwa ulusi

Kusankha njira yoyenera ndi sitepe yoyamba kwa katswiri unsembe. Kwa machitidwe omwe ali PVC kwathunthu,kuwotcherera zosungunulirandiye muyeso wamakampani. Zimapanga cholumikizira chopanda msoko, chosakanikirana chomwe chimakhala champhamvu ngati chitoliro chokha. Njirayi ndi yachangu, yodalirika komanso yokhazikika. Kulumikizana kwa ulusi kumagwiritsidwa ntchito pamene mukufuna kulumikiza mzere wanu wa PVC ku chinachake ndi ulusi wachitsulo womwe ulipo, kapena pamene mukuyembekeza kuti mukufunika kuchotsa valavu mosavuta pambuyo pake. Komabe, zomangira zapulasitiki zomangika ziyenera kuyikidwa mosamala kuti zisapangike ming'alu kuti isakhwime kwambiri. Pa mapaipi ambiri a PVC, nthawi zonse ndimalimbikitsa kulimba ndi kuphweka kwa kulumikizana kwa zosungunulira. Pamene ntchito ndiyofunikira, avalavu ya mpira wowonaamakupatsirani zabwino zonse padziko lapansi.

Njira yoyenera kukhazikitsa valavu ya mpira ndi iti?

Vavuyo imamatidwa bwino, koma tsopano chogwiriracho chimagunda khoma ndipo sichingathe kutseka. Kapena mudayika valavu yowona yogwirizana kwambiri ndi chigongono kotero kuti simungapeze wrench.

"Njira yolondola" yoyika valavu ya mpira ndiyo kukonzekera ntchito yake. Izi zikutanthawuza kuti zouma zowuma poyamba kuwonetsetsa kuti chogwiriracho chili ndi utali wathunthu wokhotakhota wa 90-digirii komanso kuti mtedza wa mgwirizano upezeke mokwanira kuti ukonzekere mtsogolo.

Valavu yowona ya Pntek yoyikidwa ndi chilolezo chokwanira chogwirira ntchito ndi mtedza wa mgwirizano

Kukhazikitsa kopambana kumadutsa chabechisindikizo chosadukiza; ndi za magwiridwe antchito anthawi yayitali. Apa ndi pamene miniti yokonzekera imapulumutsa ola la kukonzanso. Musanatsegule choyambira, ikani valavu pamalo omwe mukufuna ndikugwedeza chogwiriracho. Kodi imayenda momasuka kuchoka kutseguka mpaka kutsekedwa kwathunthu? Ngati sichoncho, muyenera kusintha mawonekedwe ake. Kachiwiri, ngati mukugwiritsa ntchito wapamwamba kwambirivalavu ya mgwirizano weniwenimonga yathu ku Pntek, muyenera kuwonetsetsa kuti mutha kupeza mtedza wamgwirizano. Cholinga cha ma valves ndi kulola kuchotsa thupi la valve popanda kudula chitoliro. Ndimakumbutsa nthawi zonse Budi kuti auze makasitomala ake izi: ngati simungathe kupeza wrench pa mtedza, mwagonjetsa cholinga chonse cha valve. Ganizirani izi ngati kukhazikitsa osati lero, koma kwa munthu yemwe akuyenera kuyigwiritsa ntchito zaka zisanu kuchokera pano.

Kodi ma valve a mpira a PVC amalunjika?

Mwakonzeka ndi simenti, koma mumayima, mwachisangalalo mukuyang'ana muvi wotuluka pa valavu. Mukudziwa kuti kukakamira valavu yolowera kumbuyo kungakhale kulakwitsa kwakukulu, kokwera mtengo.

Ayi, valavu ya mpira wa PVC yokhazikika silolowera; ndi mbali ziwiri. Imagwiritsa ntchito mawonekedwe ofananirako okhala ndi zisindikizo mbali zonse ziwiri, kuwalola kuti atseke kuyenda bwino kuchokera mbali zonse. "Mayendedwe" okhawo omwe muyenera kuda nkhawa nawo ndi momwe amagwirira ntchito kuti apeze chogwirira.

Chithunzi cha valavu ya mpira ya PVC yokhala ndi mivi yolozera mbali zonse ziwiri kusonyeza kuti ili ndi mbali ziwiri.

Ili ndi funso labwino komanso lodziwika bwino. Chenjezo lanu ndiloyenera chifukwa ma valve ena, mongafufuzani ma valvekapena ma valve a globe, ali olunjika ndipo amalephera ngati atayikidwa kumbuyo. Ali ndi muvi wosiyana pa thupi kuti ukulondolereni. Avalavu ya mpira, komabe, imagwira ntchito mosiyana. Pakatikati pake ndi mpira wosavuta wokhala ndi dzenje, womwe umazungulira kuti usindikize pampando. Popeza pali mpando kumtunda ndi kumunsi kwa mpirawo, umapanga chisindikizo cholimba mosasamala kanthu kuti kupanikizika kumachokera kuti. Choncho, mukhoza kumasuka. Simungathe kukhazikitsa valve yokhazikika ya mpira "kumbuyo" potengera kuyenda. Mapangidwe osavuta, olimba awa ndi chifukwa chimodzi chomwe amatchulira. Ingoyang'anani pakuyiyika kotero kuti chogwirizira ndi mabungwe azifika mosavuta.

Kodi mavavu a mpira a PVC ndi odalirika bwanji?

Mwawona valavu yotsika mtengo, yopanda dzina ya PVC ikusweka kapena kutayikira pakangotha chaka, ndikukupangitsani kukayikira zazinthuzo. Mukudabwa ngati muyenera kungogwiritsa ntchito valavu yachitsulo yokwera mtengo kwambiri.

Mavavu apamwamba kwambiri a PVC ndi odalirika kwambiri ndipo amatha zaka zambiri. Kutalika kwa moyo wawo kumatsimikiziridwa ndi mtundu wa zopangira (namwali vs. PVC yowonjezeredwa), kupanga kulondola, ndikuyika koyenera. Valavu yabwino nthawi zambiri imaposa dongosolo lomwe ilimo.

Kuwombera kwapafupi kowunikira kumangidwa kolimba kwa valavu ya mpira ya Pntek PVC

Kudalirika kwa aValve ya mpira wa PVCzimatsikira ku zomwe zimapangidwira ndi momwe zimapangidwira. Ichi ndiye maziko a filosofi yathu ku Pntek.

Kodi N'chiyani Chimachititsa Kudalirika?

Ubwino Wazinthu:Timalimbikira kugwiritsa ntchito100% PVC namwali. Mavavu ambiri otsika mtengo amagwiritsa ntchito zida zobwezerezedwanso kapena zodzaza, zomwe zimapangitsa pulasitiki kukhala yolimba komanso kulephera kulephera kupsinjika kapena kuwonekera kwa UV. Virgin PVC imapereka mphamvu zapamwamba komanso kukana mankhwala.
Kulondola Kupanga:Zopanga zathu zokha zimatsimikizira kuti valve iliyonse ndi yofanana. Mpira uyenera kukhala wozungulira bwino ndipo mipandoyo iyenera kukhala yosalala bwino kuti ikhale yosindikizira. Timayesa-kuyesa ma valve athu pamlingo wapamwamba kwambiri kuposa momwe angawonere m'munda.
Mapangidwe a Moyo Wautali:Zomwe zili ngati gulu lenileni la mgwirizano, EPDM kapena FKM O-rings, ndi mapangidwe olimba a tsinde zimathandiza kuti moyo ukhale wautali. Uku ndiko kusiyana pakati pa gawo lotaya ndi chuma chanthawi yayitali.

Chovala chopangidwa bwino, choyikidwa bwino cha PVC sichimalumikizana chofooka; ndi yokhazikika, yosawononga dzimbiri, komanso yotsika mtengo
