Nkhani yakudziwitsani za mavavu a mpira a PVC
PVC mpira valve ntchito
Valve ya mpira, valavu yomwe gawo lotsegula ndi lotseka (mpira) limayendetsedwa ndi tsinde la valve ndikuzungulira mozungulira tsinde la valve.Amagwiritsidwa ntchito kwambiri podula kapena kulumikiza sing'anga mu payipi.Itha kugwiritsidwanso ntchito pakusintha kwamadzimadzi ndikuwongolera.Pakati pawo, valavu ya mpira yotsekedwa mwamphamvu ya V imakhala ndi kukameta mwamphamvu pakati pa V-mawonekedwe a V ndi mpando wachitsulo wa alloy yolimba.Kumeta ubweya ndi koyenera makamaka pazofalitsa zomwe zimakhala ndi ulusi ndi tinthu ting'onoting'ono tolimba.
Valavu yamitundu yambiri papaipi sangangowongolera kusinthasintha, kusiyanasiyana, ndi kusintha koyenda kwa sing'angayo, komanso kutseka njira iliyonse yolumikizira njira zina ziwirizo.Vavu yamtunduwu nthawi zambiri iyenera kuyikidwa mopingasa mu payipi.
Gulu la valavu ya mpira: valavu ya mpira wa pneumatic, valavu yamagetsi yamagetsi, valavu ya mpira.
Zambiri Zoyambira
Nthawi zambiri, kugwiritsa ntchitopvc mpira valvesayenera upambana 45 ℃, ndi sing'anga si oyenera zosungunulira organic ndi oxidants amphamvu.Malingana ndi izi, mtundu uwu wa valve wa mpira umaletsedwa kugwiritsa ntchito madzi omwe ali pansi pa 45 ° C ndipo kupanikizika kuli kochepa kuposa 1.0mpa.
Poyerekeza ndi ma valve ena, ili ndi ubwino wotsatira.
1. Low madzimadzi kukana
Vavu ya mpira ndi yomwe ili ndi kukana kwamadzimadzi pakati pa mavavu onse, ngakhale valavu yochepetsedwa ya mpira, kukana kwake kwamadzimadzi ndikochepa.Valavu ya mpira wa PVC ndi chinthu chatsopano cha valve ya mpira chomwe chimapangidwa molingana ndi zosowa zamadzimadzi osiyanasiyana owononga mapaipi.Ubwino wazinthu: kulemera kopepuka, kukana kwamphamvu kwa dzimbiri, mawonekedwe owoneka bwino komanso owoneka bwino, kulemera kopepuka komanso kuyika kosavuta kwa thupi, kukana kwamphamvu kwa dzimbiri, kugwiritsa ntchito mitundu yosiyanasiyana, zaukhondo komanso zopanda poizoni, kukana kuvala, kusanja kosavuta, kukonza kosavuta.
Kuphatikiza pa zida zapulasitiki za PVC, mavavu apulasitiki amaphatikizanso PPR, PVDF, PPH, CPVC, etc.
2. Valavu ya mpira wa PVC ili ndi kukana kwambiri kwa dzimbiri.
Mphete yosindikiza imatengera F4.Kukana kwabwino kwa dzimbiri ndikutalikitsa moyo wautumiki.Kusinthasintha kosinthasintha komanso kosavuta kugwiritsa ntchito.
3. Monga valavu ya mpira, valavu ya mpira wa PVC ili ndi mfundo zochepa zowonongeka, mphamvu zambiri, ndipo valavu yamtundu wa kugwirizana ndi yosavuta kusonkhanitsa ndi kusokoneza.
Kuyika ndi kugwiritsa ntchito valavu ya mpira: Pamene ma flange kumbali zonse ziwiri alumikizidwa ndi payipi, mabawuti ayenera kumangidwa mofanana kuti flange isapunduke ndikuyambitsa kutayikira.Tembenuzirani chogwirira chozungulira kuti chitseke, ndipo mosemphanitsa kuti mutsegule.Itha kugwiritsidwa ntchito podula ndikuyenda, ndipo kusintha koyenda sikoyenera.Zamadzimadzi zomwe zimakhala ndi tinthu tolimba zimatha kukanda pamwamba pa mpirawo mosavuta.
4.Kugwira ntchito mwamphamvu:
Mtundu wanzeru, mtundu wofananira, sinthani mtundu uliwonse, kukula kochepa: voliyumu imangokhala pafupifupi 35% yazinthu zofanana.
5.Anthu opepuka komanso otsika mtengo:
Kulemera kwake ndi pafupifupi 30% ya zinthu zofanana, ndipo ntchitoyo ndi yodalirika: zitsulo ndi zida zamagetsi zimatengera malonda otchuka omwe amatumizidwa kunja.
6.Wokongola komanso wowolowa manja:
Aluminiyamu aloyi kufa-kuponya chipolopolo, chabwino ndi yosalala, mkulu mphamvu ndi kuvala kukana: wapadera aloyi aloyi gudumu nyongolotsi, mphamvu mkulu, zabwino kuvala kukana.
7.Chitsimikizo chachitetezo:
1500v kupirira voteji, wapadera waya loko lokhoma chingwe chingwe ndi yosavuta: gawo limodzi mphamvu magetsi, mawaya kunja makamaka losavuta.
8.Easy kugwiritsa ntchito:
Zopanda mafuta komanso zoyang'aniridwa, zotetezedwa ndi madzi komanso dzimbiri, zomwe zimayikidwa pakona iliyonse, chipangizo chotetezera: malire awiri, chitetezo cha kutentha, chitetezo chodzaza.
9. Ma liwiro angapo:
Nthawi yonse yoyenda ndi 5 mpaka masekondi a 60, kukwaniritsa zofunikira pazikhalidwe zosiyanasiyana zogwirira ntchito, mawaya apadera: gwiritsani ntchito mawaya oletsa kutentha kwamoto, omwe sakalamba akatenthedwa, ndipo ndi otetezeka komanso odalirika.

Ndi malangizo ati okonzera mavavu a mpira wa pvc?
★ Ngati valavu ya mpira ikuwotchera chifukwa cha chogwirira chotayirira, mutha kukanikiza chogwiriracho ndi vise, kenako nkuchizunguliza motsatira koloko kuti mumangitse chogwiriracho.Tiyenera kukumbukira kuti muyenera kusamala mukamangirira chogwiriracho, musagwiritse ntchito mphamvu zambiri, mwinamwake n'zosavuta kuswa valavu ya mpira.
★ Ngati malo omwe valavu ya mpira wa pvc imagwirizanitsidwa ndi chitoliro chamadzi sichimangirira, ndipo palibe chisindikizo chabwino ndipo pali kutuluka kwa madzi, mukhoza kukulunga tepi yazitsulo pozungulira malo omwe chitoliro cha madzi chikugwirizanitsidwa ndi mpira. valavu, ndi kukhazikitsa valavu mpira pambuyo akupiringa, kotero kuti sipadzakhala kutayikira madzi.
★ Ngati madzi akutuluka chifukwa cha kusweka kapena kuwonongeka kwa valavu ya mpira, valavu yakale ya mpira iyenera kupasuka, ndiyeno iyenera kukhazikitsidwa.
Tiyenera kuzindikira kuti valavu ya mpira wa pvc iyenera kugwiritsidwa ntchito moyenera panthawi ya disassembly, ndipo mfundo zazing'ono zotsatirazi ziyenera kuchitidwa.
★ Pambuyo kutseka valavu ya mpira, m'pofunika kumasula mphamvu zonse mu valavu ya mpira musanayambe kusokoneza, mwinamwake zimakhala zoopsa.Anthu ambiri salabadira izi.Valavu imachotsedwa nthawi yomweyo ikatsekedwa.Palinso kuchuluka kwa mphamvu mkati.Gawo ili la kupanikizika silimatulutsidwa ndipo silikugwirizana ndi chitetezo chaumwini.
★ Valavu ya mpira ikatha kuphwanyidwa ndikukonzedwa, imayenera kuyikidwa kumbali ina ya disassembly ndikumangirira ndi kukhazikika, apo ayi padzakhala madzi akutuluka.
Ngati mukufuna kuti valavu ya mpira wa pvc ikhale yotalikirapo, ndikofunikira kuchepetsa kuchuluka kwa masinthidwe momwe mungathere.Pakakhala kutayikira kwamadzi, muyenera kuyikonza munthawi yake molingana ndi malangizo atatu omwe ali m'nkhaniyi, ndikubwezeretsanso kugwiritsidwa ntchito moyenera mwachangu.
