PVC mpira valve ntchito
Vavu ya mpira, gawo lotsegulira ndi lotseka (mpira) limayendetsedwa ndi tsinde la valve ndikuzungulira mozungulira tsinde la valve. Amagwiritsidwa ntchito kwambiri podula kapena kulumikiza sing'anga mu payipi. Amagwiritsidwanso ntchito pakuwongolera ndi kuwongolera madzimadzi. Pakati pawo, valavu ya mpira yotsekedwa mwamphamvu ya V imakhala ndi mphamvu yamphamvu yometa ubweya pakati pa V-mawonekedwe a V ndi mpando wazitsulo wazitsulo wa carbide yopangidwa ndi simenti. Kumeta ubweya ndi koyenera makamaka pazofalitsa zomwe zimakhala ndi ulusi ndi tinthu ting'onoting'ono tolimba.
Valavu yamitundu yambiri yapaipiyo imatha kuwongolera kusinthasintha, kupatutsidwa ndi kusuntha kwamayendedwe apakati, komanso imatha kutseka njira iliyonse kuti ilumikizane ndi njira ziwiri zina. Vavu iyi 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
Kugwiritsa ntchito valavu ya mpira wa pvc nthawi zambiri sikudutsa 45 ℃, ndipo sing'angayo si yoyenera zosungunulira organic ndi ma okosijeni amphamvu. Malingana ndi izi, mtundu uwu wa valve wa mpira ukhoza kugwiritsidwa ntchito pamadzi 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 imakhala ndi kukana kwamadzi pang'ono pakati pa mavavu onse. Ngakhale valavu yocheperako ya mpira imakhala ndi kukana kwamadzi pang'ono. Valavu ya mpira wa PVC ndi chinthu chatsopano cha valve chopangidwa molingana ndi zosowa zamadzimadzi owononga mapaipi osiyanasiyana. Ubwino wazinthu: kulemera kopepuka, kukana kwamphamvu kwa dzimbiri, mawonekedwe owoneka bwino komanso owoneka bwino, kulemera kwa thupi, kuyika kosavuta, kukana kwamphamvu kwa dzimbiri, mitundu yosiyanasiyana yogwiritsira ntchito, zida zaukhondo komanso zopanda poizoni, zosavala, zosavuta kugawa, kukonza kosavuta.
Kuphatikiza pa zida zapulasitiki za PVC, mavavu apulasitiki amaphatikizanso PPR, PVDF, PPH, CPVC, etc.
2. Valve ya mpira wa PVCali ndi dzimbiri kukana.
Mphete yosindikiza imatengera F4. Kukana kwabwino kwa dzimbiri ndikutalikitsa moyo wautumiki. Kusinthasintha kosinthasintha komanso kosavuta kugwiritsa ntchito.
3. Monga valavu yofunikira ya mpira, ndiValve ya mpira wa PVCili ndi malo ochepa othawirako, mphamvu yayikulu, ndipo valavu yamtundu wamtundu wolumikizira 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. Ntchito zamphamvu:
Mtundu wanzeru, mtundu wofananira ndi mtundu wosinthira zonse zilipo, ndipo voliyumu yake ndi yaying'ono: voliyumuyo imangofanana ndi 35% yazinthu zofanana.
5. Anthu opepuka komanso otchipa:
Kulemera kwake ndi pafupifupi 30% ya zinthu zofanana, ndipo ntchitoyo ndi yodalirika: zitsulo ndi zida zamagetsi zimatumizidwa kunja kwa dzina lachidziwitso.
6. Wokongola ndi wowolowa manja:
Aluminium alloy die-casting chipolopolo, chofewa komanso chosalala, champhamvu kwambiri komanso kukana kuvala: zida zapadera zamkuwa zopangidwa ndi nyongolotsi, mphamvu zambiri komanso kukana kwamphamvu.
7. Chitsimikizo chachitetezo:
1500v kupirira voteji, waya wapadera loko chingwe loko ndi losavuta: gawo limodzi mphamvu magetsi, mawaya akunja ndi osavuta makamaka.
8. Yosavuta kugwiritsa ntchito:
Kuyang'anira malo opanda mafuta, osatetezedwa ndi madzi komanso dzimbiri, kuyika pa ngodya iliyonse, chipangizo choteteza: malire owirikiza, chitetezo cha kutentha kwambiri, chitetezo chambiri.
9. Ma liwiro angapo:
Nthawi yonse yoyenda ndi 5 mpaka masekondi a 60, omwe amatha kukwaniritsa zofunikira zamitundu yosiyanasiyana yogwirira ntchito. Waya wa kalasi yapaderayi amapangidwa ndi waya wosatentha komanso wowotcha moto, womwe sukalamba ukatenthedwa, ndi wotetezeka komanso wodalirika.

Kodi luso la kukonza ma valve a pvc ndi chiyani
★ Ngati valavu ya mpira ikuwotchera chifukwa cha chogwirira chotayirira, ikani chogwiriracho pa vise, kenaka tembenuzirani chogwiriracho mopingasa kuti chikhwime. Tiyenera kukumbukira kuti muyenera kusamala mukamangirira chogwiriracho, musagwiritse ntchito mphamvu zambiri, apo ayi valavu ya mpira idzawonongeka mosavuta.
★ Ngati kugwirizana pakati pa valavu ya mpira wa pvc ndi chitoliro cha madzi sikuli kolimba, kusindikiza sikuli bwino, ndipo pali kutuluka kwa madzi, mukhoza kukulunga valavu ya tepi pamalo pomwe chitoliro chamadzi chimagwirizanitsa mpirawo, ndikuyikapo. valavu ya mpira pambuyo pokhotakhota kuti madzi asatayike.
★ Ngati pali kutuluka kwa madzi chifukwa cha kusweka kapena kuwonongeka kwa valavu ya mpira, valavu yakale ya mpira iyenera kupasuka ndikuyikanso.
Tiyenera kuzindikira kuti valavu ya mpira wa pvc iyenera kugwiritsidwa ntchito moyenera pochotsa ndi kusonkhanitsa, ndipo mfundo zotsatirazi ziyenera kuchitidwa bwino.
★ Vavu ya mpira ikatsekedwa, kukakamiza konse mu valavu ya mpira kuyenera kutulutsidwa musanayambe kutha, apo ayi ngozi ikhoza kuchitika. Anthu ambiri salabadira izi. Sungunulani mwamsanga valve itatsekedwa. Kukadali kupsyinjika kwina kumeneko. Mbali iyi ya kukakamizidwa sikumasulidwa, zomwe sizikugwirizana ndi chitetezo chaumwini.
★ Valovu ya mpira ikatha kuphwanyidwa ndikukonzedwa, imayenera kuyikidwa mbali ina ya disassembly ndikumangika, apo ayi idzatuluka.
Ngati mukufuna kuti valavu ya mpira wa pvc ikhale yaitali, muyenera kuchepetsa chiwerengero cha masiwichi momwe mungathere. Pamene madzi akutuluka, muyenera kukonza nthawi yake molingana ndi malangizo atatu omwe ali m'nkhaniyi, ndikubwerera kuntchito yachizolowezi mwamsanga.
