A PVC compact mpira valveamasiya kuchucha asanayambe. Mapangidwe ake apamwamba osindikizira amasunga madzi mu mipope. Alimi ndi alimi amakhulupirira valavu iyi kuti ikhale ndi chitetezo cholimba, chokhalitsa.
Mavavu odalirika amatanthauza madzi osawonongeka komanso kukonzanso kochepa. Sankhani njira yanzeru iyi kuti mukhale ndi mtendere wamumtima ndi nthawi iliyonse yothirira.
Zofunika Kwambiri
- Mavavu a PVC compact mpira amapanga chisindikizo cholimba, chosadukiza chomwe chimasunga madzi mkati mwa mapaipi, kusunga madzi ndikuchepetsa kukonza.
- Mavavuwa amalimbana ndi dzimbiri ndi kutha, zomwe zimatha zaka 25 ngakhale m'mikhalidwe yovuta kwambiri yothirira, zomwe zimachepetsa mtengo wokonza.
- Mapangidwe awo osavuta, opepuka amapangitsa kukhazikitsa kukhala kosavuta ndikuchepetsa kukonzanso, kupatsa alimi ndi olima madzi odalirika nyengo iliyonse.
Momwe PVC Compact Ball Valve Imapewera Kutuluka
Kusindikiza Njira ndi Mapangidwe
Valavu ya mpira wa PVC imagwiritsa ntchito kapangidwe kanzeru kuti ayimitse kutayikira asanayambe. Mpira mkati mwa valavu umapangidwa molondola. Imazungulira bwino kuti itsegule kapena kutseka kutuluka, ndikupanga chisindikizo chapafupi nthawi zonse. Mipando ndi zisindikizo, zopangidwa kuchokera ku zipangizo zolimba monga EPDM kapena FPM, zimakanikiza mpirawo mwamphamvu. Kukwanira kumeneku kumalepheretsa madzi kutuluka, ngakhale atapanikizika kwambiri.
Zinthu zazikulu zomwe zimathandiza kupewa kutayikira ndi monga:
- Mpira wopangidwa mwaluso kwambiri wopangidwa kuchokera ku PVC wapamwamba kwambiri kuti usindikize zolimba.
- Zisindikizo zolimbikitsidwa zomwe zimayendetsa kuthamanga kwambiri popanda kulephera.
- Kukula kophatikizika komwe kumakwanira mumipata yothina ndikuchepetsa kutayikira komwe kungatheke.
- Chogwirizira cha kotala chomwe chimalola kugwira ntchito kosavuta, kolondola.
- Mapangidwe osavuta, olimba omweamachepetsa zosowa zosamalira komanso kuwopsa kwa kutayikira.
Vavu iliyonse imadutsa pakuwunika kokhazikika komanso kuyesa kutayikira musanachoke kufakitale. Izi zimawonetsetsa kuti valavu iliyonse ya PVC yophatikizika ya mpira imapereka magwiridwe odalirika, opanda kutayikira m'munda.
Njira yosindikizira imagwiritsanso ntchito mphete ya O-owiri pa tsinde la valve. Kapangidwe kameneka kamapangitsa kuti madzi asatayike mozungulira chogwiriracho, ngakhale makinawo akathamanga kwambiri. Tebulo ili m'munsiyi likuwonetsa momwe zinthuzi zimagwirira ntchito limodzi:
| Mbali | Tsatanetsatane |
|---|---|
| Chisindikizo Design | Mapangidwe amtundu wa O-ring tsinde |
| Mulingo Wabwino Wogwira Ntchito | 150 PSI pa 73°F (22°C) |
| Zinthu Zakuthupi | Zosamva dzimbiri, zolimba, zotetezeka, zosavala |
| Kachitidwe | Kusindikiza kodalirika, koyenera madzi ndi zakumwa zopanda dzimbiri |
| Ubwino wake | Kukana kwamadzimadzi otsika, opepuka, kuyika kosavuta ndi kukonza, moyo wautali wautumiki |
| Kugwiritsa ntchito | Kuchiza madzi, kunyamula mankhwala, kuchimbudzi, kuthirira |
Valavu ya PVC yaying'ono imatha kukhala kwa zaka zambiri. Mitundu yambiri imagwira ntchito yopitilira 500,000 yotseguka komanso yotseka. Ndi chisamaliro choyenera, zisindikizo ndi mipando zimagwira ntchito kwa zaka 8 mpaka 10 kapena kuposerapo, ngakhale ndikugwiritsa ntchito tsiku ndi tsiku.
Kulimba kwa Zinthu Zakuthupi ndi Kukaniza Kuwonongeka
Mphamvu ya valavu ya mpira wa PVC imachokera ku thupi lake lolimba la UPVC ndi chogwirira cha ABS. Zidazi zimakana ma acid ndi ma alkalis, zomwe zimapangitsa kuti valavu ikhale yabwino m'malo ovuta monga jekeseni wa feteleza kapena kuthirira kwamankhwala. Valavu imayimilira kuti ikhudzidwe ndi kupanikizika, kotero sichimasweka kapena kusweka mosavuta.
PVC imapereka maubwino angapo kuposa mavavu achitsulo:
- Sichita dzimbiri, dzenje, kapena sikelo, ngakhale m'makina okhala ndi feteleza wamphamvu kapena mankhwala.
- Malo osalala, osakhala ndi porous amatsutsana ndi kuchulukana ndipo amachititsa kuti madzi aziyenda momasuka.
- PVC safuna zokutira zowonjezera kapena chitetezo, zomwe zimachepetsa ndalama zosamalira.
- Zinthuzi zimakhala zolimba pa kutentha kwakukulu, choncho zimagwira ntchito m'madera ambiri.
Mavavu a PVC ophatikizana a mpira amakhala nthawi yayitali kuposa mavavu ambiri azitsulo m'malo ovuta. Nthawi zambiri amagwira ntchito kwa zaka 25 kapena kuposerapo, osafunikira kukonzanso.
Kukana kwa dzimbiri kwa PVC kumatanthauza kuti imasunga mphamvu zake ndikusindikiza mphamvu zake chaka ndi chaka. Mosiyana ndi mavavu achitsulo, omwe amatha kulephera chifukwa cha dzimbiri kapena kuukira kwa mankhwala, valavu ya mpira wa PVC imasunga njira zothirira popanda kutayikira komanso zodalirika. Kukhazikika kumeneku kumapulumutsa nthawi, ndalama, ndi madzi, ndikupangitsa kukhala chisankho chanzeru pantchito iliyonse yothirira.
PVC Compact Ball Valve vs. Mavavu Achikhalidwe
Mavuto Ochulukirachulukira M'ma Vavu Ena
Ma valve othirira, monga zipata kapena ma valve a globe, nthawi zambiri amalimbana ndi kutayikira. Izi zimataya madzi ndikuwononga ndalama zokonzanso. Ogwiritsa ntchito ambiri amawona zovuta monga kutuluka kwamadzimadzi kuchokera ku tsinde la valve kapena madzi akutuluka ngakhale valavu itatsekedwa. Gome ili m'munsili likuwonetsa zovuta zomwe zimachulukirachulukira komanso zomwe zimayambitsa:
| Nkhani ya Leakage | Kufotokozera | Zomwe Zimayambitsa |

| Kutuluka kwa Valve Stem | Mpweya kapena madzimadzi amatuluka kudzera mu tsinde la valve chifukwa cha brittleness kapena kusweka kwa valve tsinde. | Kuwonongeka kwa tsinde, mankhwala apamsewu, kuwonongeka kwa tsinde, kudzikundikira zinyalala. |
| Kutayikira kwa Mpando Chisindikizo | Madzi amatuluka pamene valve yatsekedwa chifukwa cha kuwonongeka kwa chisindikizo kapena kuwonongeka. | Zisindikizo zouma komanso zotenthedwa chifukwa chosowa mafuta, kutentha kwamphamvu komwe kumapangitsa kuti chisindikizo chiwotche kapena kusweka. |
| Kutuluka Pamene Kutseka Vavu | Vavu imalephera kusindikiza kwathunthu, kulola kutayikira kudera la mpando. | Kusindikiza kuuma, kuwonongeka kwa kutentha, malo osayenera kapena ma valve owonongeka. |
| Kutuluka Pakati pa Actuator & Valve | Kutayikira komwe kumachitika chifukwa chofananira ndi mipando yosayenera kapena kuwonongeka kwa liner. | Zing'onozing'ono pampando wapampando, mpando wowonongeka kapena wowonongeka O-ring, actuator misalignment. |
Ambiri mwa mavutowa amabwera chifukwa cha zidindo zakale, dzimbiri, kapena kusayenda bwino. Nkhanizi zingayambitse kukonzanso pafupipafupi komanso kuwononga chuma.
Kuchita Kwapamwamba ndi Kudalirika
A PVC compact mpira valveimapereka mwayi womveka bwino kuposa mavavu achitsulo achikhalidwe. Imalimbana ndi dzimbiri, motero sichita dzimbiri kapena sikelo. Khoma losalala lamkati limapangitsa kuti madzi asamayende bwino komanso kuti asamangidwe. Valavu iliyonse imadutsa pakuwunika kokhazikika komanso kuyezetsa kukakamiza, kuwonetsetsa kuti njira zonse zothirira zikuyenda bwino.
Tebulo ili m'munsiyi likufanizira ma metrics ofunikira:
| Performance Metric | PVC Compact Ball Valves | Ma Vavu Achitsulo Achikhalidwe |
|---|---|---|
| Kukaniza kwa Corrosion | Kukana kwamphamvu kwa dzimbiri, PVC yapamwamba kwambiri | Wokonda dzimbiri komanso makulitsidwe |
| Ntchito Zaukhondo | Palibe mvula yachitsulo yolemera, yotetezeka komanso yathanzi | Kuthekera kwa mphepo ya heavy metal |
| Kulemera | Zopepuka, zosavuta kukhazikitsa ndi zoyendetsa | Zolemera, zovuta kuzigwira |
| Moyo Wautumiki | Osachepera zaka 25, otsika kukonza | Moyo waufupi, kukonza zambiri kumafunika |
| Kusalala Kwamkati Kwakhoma | Zosalala, zimachepetsa makulitsidwe ndi kuyipitsa | Zovuta, zomangika kwambiri |
