Zinganenedwe kuti ma valve amatha kuwoneka kulikonse m'moyo, kaya ndi nyumba kapena fakitale, nyumba iliyonse imakhala yosalekanitsidwa ndi valve.Ena,Malingaliro a kampani Newsway Valve CO., LTDikuwonetsani magawo angapo omwe amagwiritsidwa ntchito ndi ma valve:

1. Mavavu oyika mafuta a petroleum

①.Chomera choyenga, mavavu ambiri omwe amafunikira pafakitale yoyenga mafuta ndi mavavu a mapaipi, makamaka valavu yachipata, valavu yapadziko lonse lapansi, valavu yoyang'ana, valavu yachitetezo, valavu ya mpira, valavu ya butterfly, msampha wa nthunzi, pakati pawo, valavu ya pachipata imakhala pafupifupi 80% kuchuluka kwa ma valve, (Vavu imakhala ndi 3% mpaka 5% ya ndalama zonse za chipangizocho);②.Chipangizo cha Chemical CHIKWANGWANI, mankhwala CHIKWANGWANI mankhwala makamaka magulu atatu: poliyesitala, akiliriki, ndi vinylon.Vavu ya mpira ndi valavu yokhala ndi jekete (valavu ya mpira wa jekete, valavu yachipata cha jekete, valavu ya globe) ya valve yofunikira;③.Chipangizo cha Acrylonitrile.Chipangizochi nthawi zambiri chimafunika kugwiritsa ntchito ma valve opangidwa mokhazikika, makamaka ma valve olowera pachipata, ma valavu a globe, ma valavu owunika, ma valve a mpira, misampha ya nthunzi, mavavu a singano, ndi ma plug.Pakati pawo, ma valve a pakhomo amakhala pafupifupi 75% ya ma valve okwana;④.Synthetic ammonia chomera .Chifukwa kaphatikizidwe ka gwero la ammonia ndi njira zoyeretsera ndizosiyana, kuyenda kwa njira kumakhala kosiyana, ndipo ntchito zaukadaulo zama valve ofunikira ndizosiyana.Pakali pano, zoweta ammonia chomera makamaka zofunikavalve pachipata, valavu ya globe, chekeni valavu, msampha wa nthunzi,valavu ya butterfly, valavu ya mpira, valavu ya diaphragm, valve yoyendetsera, valve ya singano, valavu yotetezera, kutentha kwakukulu ndi valavu yotsika kutentha;

2. Mavavu omwe amagwiritsidwa ntchito m'malo opangira mphamvu zamagetsi

Ntchito yomanga malo opangira magetsi m'dziko langa ikupita patsogolo pakukula kwakukulu, mavavu otetezedwa ndi mainchesi akulu komanso othamanga kwambiri, ma valve ochepetsa mphamvu,ma valve a globe, ma valve pachipata, valavu butterfly, ma valve otseka mwadzidzidzi, ma valve oyendetsa madzi, ndi zida zosindikizira zozungulira zimafunika.Globe vavu, (malinga ndi dziko "Chakhumi Zaka zisanu Plan", kuwonjezera Inner Mongolia ndi Guizhou zigawo akhoza kumanga oposa 200,000 kilowatt mayunitsi, zigawo zina ndi mizinda akhoza kumanga oposa 300,000 kilowatts mayunitsi);

3. Valavu yogwiritsira ntchito zitsulo

M'makampani opanga zitsulo, machitidwe a alumina amafunikira makamaka valavu yosamva slurry (mu-flow stop valve) ndi msampha wowongolera.Makampani opanga zitsulo amafunikira makamaka ma valve otsekedwa ndi zitsulo, ma valve a butterfly ndi ma valve a oxide mpira, ma valve oyimitsa ndi njira zinayi;

4. Ma valve ogwiritsira ntchito panyanja

Ndi chitukuko cha kugwiritsa ntchito mafuta m'mphepete mwa nyanja, kuchuluka kwa mavavu ofunikira pakukula kwapanyanja kwakula pang'onopang'ono.Mapulatifomu akunyanja akuyenera kugwiritsa ntchito ma valve otseka, ma valve owunika ndi ma valve anjira zambiri;

5. Mavavu opangira chakudya ndi mankhwala

zitsulo zosapanga dzimbiri mavavu mpira, sanali poizoni zonse pulasitiki mavavu mpira ndi agulugufe valavu amagwiritsidwa ntchito kwambiri mu makampani.Pakati pamagulu 10 omwe ali pamwambawa a zinthu za valve, kufunikira kwa ma valve opangidwa ndi cholinga ndipamwamba kwambiri, monga ma valve a zida, ma valve a singano, ma valve a singano, ma valve a zipata, ma valve a globe, ma valve oyendera, ma valve a mpira, ndi ma valve a butterfly;

6. Mavavu omwe amagwiritsidwa ntchito m'nyumba zakumidzi ndi zakumidzi

ma valve otsika kwambiri amagwiritsidwa ntchito pamakina omanga m'matauni, ndipo pakali pano akupanga njira yoteteza chilengedwe ndi kupulumutsa mphamvu.Mavavu amtundu wa rabara, mavavu oyendera bwino, mavavu agulugufe apakati, ndi ma valve agulugufe omata zitsulo pang'onopang'ono akulowa m'malo mwa zipata zachitsulo zotsika.Mavavu ambiri omwe amagwiritsidwa ntchito m'nyumba zam'matauni ndi mavavu oyendera bwino, ma valve otsekedwa ndi zipata, ma valve agulugufe, ndi zina zotero;

7. Mavavu otenthetsera akumidzi ndi akumidzi

M'machitidwe otenthetsera akumidzi, ma valve agulugufe osindikizidwa ndi zitsulo, ma valve opingasa opingasa ndi ma valve okwiriridwa mwachindunji amafunikira.Ma valve awa amathetsa vuto la kusalinganika kwa hydraulic moyima komanso yopingasa mu payipi, ndikukwaniritsa kupulumutsa mphamvu ndi kupanga.cholinga cha kutentha kwapakati.

8. Mavavu a ntchito zoteteza chilengedwe

M'makina oteteza zachilengedwe m'nyumba, njira yoperekera madzi imafuna ma valve agulugufe apakati, mavavu otsekedwa ndi zipata, ma valve a mpira, ndi ma valve otulutsa mpweya (omwe amagwiritsidwa ntchito pochotsa mpweya mupaipi).Dongosolo lachimbudzi limafunikira valavu yotsekera pachipata ndi valavu yagulugufe;

9. Mavavu a gasi

Gasi wamzinda umapanga 22% ya msika wonse wachilengedwe, ndipo kuchuluka kwa ma valve ndi kwakukulu ndipo pali mitundu yambiri.Amafunika kwambiri valavu ya mpira, valavu ya pulagi, valavu yochepetsera kuthamanga, valavu yotetezera;

10. Ma valve ogwiritsira ntchito mapaipi

mapaipi aatali amakhala makamaka mafuta amafuta, zinthu zomalizidwa ndi mapaipi achilengedwe.Mavavu omwe amagwiritsidwa ntchito kwambiri pamapaipi oterowo ndi zitsulo zonyezimira zokhala ndi magawo atatu, mavavu odana ndi sulfure, mavavu oteteza chitetezo, ndi ma valve otsimikizira.
