Valve ya mpira wamkuwa, membala wotsegulira ndi wotseka (mpira) amayendetsedwa ndi tsinde la valve ndikuzungulira mozungulira valavu ya mpira.Itha kugwiritsidwanso ntchito pakuwongolera ndi kuwongolera madzimadzi.Pakati pawo, valavu yolimba yosindikizidwa yooneka ngati V imakhala ndi mphamvu yometa ubweya pakati pa pakati pa V-woboola pakati pa V-woboola pakati ndi mpando wazitsulo wazitsulo wazitsulo zolimba za alloy sufacing, zomwe zimakhala zoyenera makamaka kwa ulusi ndi tinthu ting'onoting'ono tolimba.ndi zina zapakati.Valavu yamitundu yambiri yapaipiyo imatha kuwongolera kusinthasintha, kutembenuka, ndi kusintha kwamayendedwe apakati, komanso imatha kutseka njira iliyonse ndikulumikiza njira zina ziwiri.Vavu yamtunduwu nthawi zambiri iyenera kuyikidwa mopingasa mu payipi.Vavu ya mpira imagawidwa kukhala: valavu ya mpira wa pneumatic, valavu yamagetsi yamagetsi, valavu ya mpira wamanja malinga ndi njira yoyendetsera galimoto.

Zochita za valve ya mpira:
1. Zosavala;chifukwa valavu pachimake cha molimba losindikizidwaValve ya mpira wamkuwandi kuwotcherera chitsulo cha aloyi,
Mphete yosindikiza imapangidwa ndi chitsulo cha alloy pamwamba, kotero kuti valavu ya mpira yotsekedwa mwamphamvu sichidzatulutsa kuvala kwambiri ikayatsidwa ndi kuzimitsa.(Kuuma kwake ndi 65-70):
Chachiwiri, ntchito yosindikiza ndi yabwino;chifukwa kusindikizidwa kwa valavu ya mpira wotsekedwa mwamphamvu kumapangidwira pansi, sikungagwiritsidwe ntchito mpaka pakati pa valve ndi mphete yosindikizira zikugwirizana.Kotero ntchito yake yosindikiza ndi yodalirika.
Chachitatu, chosinthira ndi chopepuka;chifukwa pansi pa mphete yosindikizira ya valavu yotsekedwa mwamphamvu imatenga kasupe kuti igwire mphete yosindikizira ndi chigawo cha valve mwamphamvu palimodzi, kusinthaku kumakhala kowala kwambiri pamene mphamvu yakunja ikupitirira kudzaza kasupe.
4. Moyo wautali wautumiki: Wagwiritsidwa ntchito kwambiri mu mafuta, mafakitale a mankhwala, kupanga magetsi, kupanga mapepala, mphamvu za atomiki, ndege, roketi ndi madipatimenti ena, komanso moyo wa tsiku ndi tsiku wa anthu.
Valve ya mpira wa pneumatic ili ndi mawonekedwe osavuta komanso ophatikizika, kusindikiza kodalirika komanso kukonza bwino.Malo osindikizira ndi ozungulira amakhala otsekedwa nthawi zonse, omwe sawonongeka mosavuta ndi sing'anga, ndipo ndi osavuta kugwiritsa ntchito ndi kusamalira.Ndi oyenera ntchito wamba TV monga madzi, zosungunulira, asidi ndi gasi.Amagwiritsidwa ntchito kwambiri podula Kapena kulumikiza sing'anga mu payipi, ndipo angagwiritsidwenso ntchito kulamulira madzimadzi ndi kulamulira.
Poyerekeza ndi mitundu ina ya mavavu, mavavu a mpira wa pneumatic ali ndi torque ya angular stroke, kutseguka mwachangu, kokhazikika komanso kodalirika, kugwiritsa ntchito kwakukulu, ndi zabwino zotsatirazi:
1. Kuwongolera kumachepetsa kugunda kwa tsinde la valve, komwe kumapangitsa kuti tsinde la valve lizigwira ntchito bwino komanso mosasunthika.
2. Anti-static function: Kasupe amayikidwa pakati pa mpira, tsinde la valve ndi thupi la valve, lomwe lingathe kutumiza magetsi osasunthika omwe amapangidwa panthawi ya kusintha.
3. Chifukwa cha zabwino zodzipangira mafuta a PTFE ndi zipangizo zina, kutayika kwa mikangano ndi mpira kumakhala kochepa, kotero moyo wautumiki wa valavu ya pneumatic mpira ndi yaitali.
4. Kukana kwamadzimadzi kakang'ono: Valavu ya mpira wa pneumatic ndi imodzi mwa mitundu yaying'ono yamadzimadzi pakati pa magulu onse a valve.Ngakhale valavu yochepetsera m'mimba mwake ya pneumatic mpira, kukana kwake kwamadzimadzi kumakhala kochepa kwambiri.
5. Chisindikizo chodalirika cha valve tsinde: Popeza tsinde la valve limangozungulira ndipo silisuntha mmwamba ndi pansi, chisindikizo chonyamulira cha tsinde la valve sichiri chosavuta kuonongeka, ndipo mphamvu yosindikiza imawonjezeka ndi kuwonjezeka kwapakati papakati.
6. Mpando wa valve uli ndi ntchito yabwino yosindikizira: mphete yosindikizira yopangidwa ndi zinthu zotanuka monga PTFE ndizosavuta kusindikiza mwadongosolo, ndipo mphamvu yosindikiza ya valve ya pneumatic ya mpira ikuwonjezeka ndi kuwonjezeka kwapakati papakati.
7. Kukana kwamadzimadzi kumakhala kochepa, ndipo valavu yodzaza mpira imakhala yopanda kukana.
8. Mapangidwe osavuta, kukula kochepa ndi kulemera kochepa.
9. Zolimba komanso zodalirika.Lili ndi malo awiri osindikizira, ndipo zipangizo zosindikizira za valve ya mpira zimagwiritsidwa ntchito kwambiri m'mapulasitiki osiyanasiyana, omwe ali ndi ntchito yabwino yosindikiza ndipo amatha kukwaniritsa kusindikiza.Amagwiritsidwanso ntchito kwambiri m'makina a vacuum.
10. Kuchita kosavuta, kutsegula ndi kutseka mwamsanga, valavu ya mpira imangofunika kuzungulira 90 ° kuchokera kutseguka kwathunthu mpaka kutsekedwa kwathunthu, komwe kuli kosavuta kulamulira mtunda wautali.
11. Ndikosavuta kusamalira, valavu ya mpira imakhala ndi dongosolo losavuta, mphete yosindikizira nthawi zambiri imasunthika, ndipo ndiyosavuta kusokoneza ndikusintha.
12. Mukatsegulidwa kwathunthu kapena kutsekedwa kwathunthu, malo osindikizira a mpira ndi mpando wa valve amasiyanitsidwa ndi sing'anga, ndipo pamene sing'anga ikudutsa, sichidzayambitsa kukokoloka kwa malo osindikizira a valve.
13. Mitundu yosiyanasiyana ya ntchito, ma diameter kuyambira ang'onoang'ono mpaka mamilimita angapo, aakulu mpaka mamita angapo, ndipo angagwiritsidwe ntchito kuchokera ku vacuum yapamwamba mpaka kupanikizika kwambiri.
14. Chifukwa valavu ya mpira imakhala ndi katundu wopukuta panthawi yotsegula ndi kutseka, ingagwiritsidwe ntchito pakatikati ndi tinthu tating'ono tomwe timayimitsidwa.
15. High processing mwatsatanetsatane ndi mtengo wapamwamba.Siliyenera kugwiritsidwa ntchito kutentha kwambiri.Ngati pali zonyansa mu payipi, n'zosavuta kutsekedwa ndi zonyansa, zomwe zimapangitsa kuti valavu isatsegulidwe.
