Nkhani yoti mudziweMa valve a mpira wa PVC
Ntchito ya valavu ya mpira wa PVC
Valavu ya mpira, gawo lotsegulira ndi lotseka (mpira) limayendetsedwa ndi tsinde la valavu ndipo limazungulira mozungulira tsinde la valavu. Amagwiritsidwa ntchito makamaka kudula kapena kulumikiza cholumikizira chomwe chili mupaipi. Amagwiritsidwanso ntchito powongolera ndi kulamulira madzi. Pakati pawo, valavu ya mpira yolimba yomangidwa ngati V ili ndi mphamvu yolimba yometa pakati pa pakati pa V ndi mpando wa valavu yachitsulo ya carbide yolimba. Mphamvu yometa ndi yoyenera makamaka pazinthu zokhala ndi ulusi ndi tinthu tating'onoting'ono tolimba.
Vavu ya mpira wa njira zambiri pa payipi siingathe kungowongolera mosinthasintha momwe njira yolumikizirana, kusinthasintha ndi kusinthasintha kwa madzi imagwirira ntchito, komanso imatha kutseka njira iliyonse kuti ilumikize njira zina ziwiri. Vavu iyi nthawi zambiri iyenera kuyikidwa mopingasa mu payipi.
Gulu la mavavu a mpira: valavu ya mpira wa pneumatic, valavu ya mpira wamagetsi, valavu ya mpira wamanja.
Chidziwitso Choyambira
Kugwiritsa ntchito valavu ya mpira wa PVC nthawi zambiri sikupitirira 45 ℃, ndipo sikoyenera kugwiritsa ntchito zinthu zosungunulira zachilengedwe komanso ma oxidant amphamvu. Malinga ndi izi, valavu yamtundu uwu ingagwiritsidwe ntchito pamadzimadzi omwe ali pansi pa 45°C ndipo kuthamanga kwake ndi kochepera 1.0mpa.
Poyerekeza ndi ma valve ena, ili ndi ubwino wotsatira.
1. Kukana madzi pang'ono
Valavu ya mpira ili ndi kukana kwamadzimadzi kochepa kwambiri pakati pa mavavu onse. Ngakhale valavu ya mpira yocheperako imakhala ndi kukana kochepa kwamadzimadzi. Valavu ya mpira ya PVC ndi chinthu chatsopano cha valavu ya mpira chomwe chimapangidwa malinga ndi zosowa za madzi osiyanasiyana owononga mapaipi. Ubwino wa chinthucho: kulemera kopepuka, kukana dzimbiri mwamphamvu, mawonekedwe ang'onoang'ono komanso okongola, kulemera kwa thupi kopepuka, kuyika kosavuta, kukana dzimbiri mwamphamvu, kugwiritsa ntchito mosiyanasiyana, zinthu zaukhondo komanso zopanda poizoni, zosawonongeka, zosavuta kusokoneza, kukonza kosavuta.
Kuwonjezera pa zipangizo za pulasitiki za PVC, ma valve a mpira apulasitiki amakhalanso ndi PPR, PVDF, PPH, CPVC, ndi zina zotero.
2. Valavu ya mpira wa PVCali ndi kukana dzimbiri kwabwino kwambiri.
Mphete yotsekera imagwiritsa ntchito F4. Imatha kupirira dzimbiri bwino komanso imawonjezera nthawi yogwira ntchito. Yosinthasintha komanso yosavuta kugwiritsa ntchito.
3. Monga valavu yolumikizira mpira,Valavu ya mpira wa PVCIli ndi malo ochepa otayira madzi, mphamvu zambiri, ndipo valavu ya mpira yamtundu wolumikizira ndi yosavuta kuisonkhanitsa ndikuyichotsa.
Kukhazikitsa ndi kugwiritsa ntchito valavu ya mpira: Pamene ma flanges kumapeto onse awiri alumikizidwa ndi payipi, ma bolts ayenera kumangidwa mofanana kuti flange isawonongeke ndikuyambitsa kutuluka kwa madzi. Tembenuzani chogwiriracho mozungulira kuti chitseke, ndipo mosemphanitsa kuti chitseguke. Chingagwiritsidwe ntchito kokha podula ndi kufalikira kwa madzi, ndipo kusintha kwa madzi sikoyenera. Zakumwa zokhala ndi tinthu tolimba zimatha kukanda mosavuta pamwamba pa mpirawo.
4. Ntchito zamphamvu:
Mtundu wanzeru, mtundu wofanana ndi mtundu wa switch zonse zilipo, ndipo voliyumu yake ndi yaying'ono: voliyumuyo ndi yofanana ndi pafupifupi 35% ya zinthu zofanana.
5. Anthu opepuka komanso otsika mtengo:
Kulemera kwake ndi pafupifupi 30% yokha ya zinthu zofanana, ndipo magwiridwe antchito ake ndi odalirika: mabearing ndi zida zamagetsi ndi zinthu zodziwika bwino zochokera kunja.
6. Wokongola komanso wopatsa:
Chipolopolo chopangidwa ndi aluminiyamu, chofewa komanso chosalala, champhamvu komanso cholimba: zida zapadera zopangidwa ndi nyongolotsi zopangidwa ndi aloyi yamkuwa, champhamvu kwambiri komanso cholimba bwino.
7. Chitsimikizo cha chitetezo:
Mphamvu ya 1500v yolimbana ndi magetsi, chingwe chotchingira chapadera cha waya ndi chosavuta: magetsi a gawo limodzi, mawaya akunja ndi osavuta kwambiri.
8. Yosavuta kugwiritsa ntchito:
Kuyang'ana malo opanda mafuta, osalowa madzi komanso osachita dzimbiri, kuyika kulikonse, chipangizo choteteza: malire awiri, chitetezo chotentha kwambiri, chitetezo chopitirira muyeso.
9. Ma liwiro angapo:
Nthawi yonse yoyendera ndi masekondi 5 mpaka 60, zomwe zingakwaniritse zofunikira pazochitika zosiyanasiyana zogwirira ntchito. Waya wapaderawu umapangidwa ndi waya wosatentha komanso woletsa moto, womwe sukalamba ukatenthedwa, ndipo ndi wotetezeka komanso wodalirika.

Kodi luso la kukonza ma valve a mpira wa PVC ndi liti?
★ Ngati valavu ya mpira yatuluka chifukwa cha chogwirira chomasuka, gwirani chogwiriracho mu vise, kenako tembenuzani chogwiriracho mozungulira kuti chikhale cholimba. Dziwani kuti muyenera kusamala mukamanga chogwiriracho, musagwiritse ntchito mphamvu zambiri, apo ayi valavu ya mpirayo ingawonongeke mosavuta.
★ Ngati kulumikizana pakati pa valavu ya mpira wa PVC ndi chitoliro cha madzi sikuli kolimba, kutseka sikuli bwino, ndipo pali kutayikira kwa madzi, mutha kukulunga valavu ya tepi ya zinthu zopangira pamalo pomwe chitoliro cha madzi chimalumikiza mpirawo, ndikuyika valavu ya mpirayo mutapinda kuti madzi asatayike.
★ Ngati madzi atuluka chifukwa cha kusweka kapena vuto la valavu ya mpira, valavu yakale ya mpira iyenera kuchotsedwa ndikuyiyikanso.
Tiyenera kudziwa kuti valavu ya mpira wa PVC iyenera kugwiritsidwa ntchito bwino pochotsa ndi kusonkhanitsa, ndipo mfundo zotsatirazi ziyenera kuchitidwa bwino.
★ Valvu ya mpira ikatsekedwa, kupanikizika konse mu valavu ya mpira kuyenera kutulutsidwa musanachotsedwe, apo ayi ngozi ingachitike. Anthu ambiri salabadira izi. Chotsani nthawi yomweyo valavu ikatsekedwa. Palinso kupanikizika pang'ono mkati mwake. Gawo ili la kupanikizika silinatulutsidwe, zomwe sizingathandize pa chitetezo cha munthu.
★ Valvu ya mpira ikachotsedwa ndi kukonzedwa, iyenera kuyikidwa mbali ina ya kuchotsedwako ndikuyilimbitsa, apo ayi idzatuluka madzi.
Ngati mukufuna kuti valavu ya mpira wa PVC ikhale nthawi yayitali, muyenera kuchepetsa kuchuluka kwa ma switch momwe mungathere. Madzi akatuluka, muyenera kukonza nthawi yake malinga ndi malangizo atatu omwe ali m'nkhaniyi, ndikuyambiranso kugwiritsa ntchito mwachizolowezi mwachangu momwe mungathere.
