DN1800 yokulirapo kwambirivalavu ya thumba la bakhaIli ndi kapangidwe kosinthika ka cheke ka rabara komwe kamatseguka ndikutseka kokha ndi kusiyana kwapakati pa kuthamanga. Poyerekeza ndi zipata zachitsulo zachikhalidwe ndi ma valve owunikira gulugufe, imapereka zabwino zodabwitsa ndipo imagwiritsidwa ntchito kwambiri m'mapulojekiti akuluakulu osamalira madzi ndi madzi otuluka m'matauni.

Ubwino wa Ma Vavu a Flanged Rubber Duckbill

1. Chopangidwa ngati gawo lofunikira la rabala lopanda ma spindle amakina kapena magawo otsegula/kutseka osuntha, valavuyi siikhudzidwa ndi dzimbiri ndi dzimbiri. Ngakhale pamene dothi, miyala kapena zinyalala zili pamalo otulukira valavu, kusinthasintha kwa rabalayi kumathandiza kutseka bwino, makamaka kuthetsa mavuto okhudzana ndi kutsekeka ndi kutuluka kwa madzi.

2. Kutsegula ndi kutseka kumayendetsedwa ndi kusiyana kwa kuthamanga kwa madzi popanda kulamulira kwamagetsi kapena kugwiritsa ntchito pamanja. Kumagwira ntchito mwakachetechete popanda phokoso lalikulu ndipo kumafuna kutayika kochepa kwa mutu kuti utsegule, zomwe zimachepetsa mphamvu yogwiritsira ntchito potulutsa madzi.

3. Sikofunikira kukonza kapena kudzola mafuta nthawi zonse, ndipo nthawi yogwira ntchito ndi yoposa zaka khumi. Imapezeka m'mapangidwe olumikizirana okhala ndi flange komanso socket-end, imakwanira mapaipi achitsulo, mapaipi a konkire ndi mapaipi akuluakulu a FRP kuti ikhale yosavuta kuyiyika komanso kuchepetsa mtengo wonse wa ntchito.

4. Mitundu ya rabara yosankha kuphatikizapo rabara ya nitrile, neoprene ndi EPDM imapereka kukana bwino kwambiri ku asidi, alkali ndi dzimbiri la m'nyanja, zomwe zimagwirizana ndi zimbudzi, matope ndi madzi amchere.

Chiwerengero cha Ntchito

Vavu nthawi zambiri imayikidwa pa mapaipi akuluakulu otulutsira madzi m'mizinda ndi m'malo otulutsira madzi otayira m'malo akuluakulu oyeretsera madzi otayira kuti madzi osefukira asamabwerere m'madzi kupita ku zomera ndi m'malo otulutsira madzi m'mizinda nthawi ya kusefukira kwa madzi. Pa malo osungira madzi m'mphepete mwa nyanja ndi m'malo otulutsira madzi osefukira m'mphepete mwa nyanja, imalowa m'malo mwa zipata zazikulu zachitsulo kuti ziletse kusefukira kwa madzi m'nyanja. Imayikidwanso m'malo otayira madzi m'malo osungira madzi ndi m'malo otulutsira madzi m'malo akuluakulu otulutsira madzi kuti madzi asefukire kwambiri komanso kuti madzi asefukire akamatseka. Kuphatikiza apo, imagwiritsidwa ntchito ngati chida chowunikira njira imodzi ya mizere yayikulu yotulutsira madzi amvula m'misewu yayikulu ndi m'mabwalo a ndege, komanso mizere yamadzi otayira m'mafakitale m'malo osungira mankhwala, kuletsa kutuluka kwa fungo ndikuteteza maukonde a mapaipi kuti asabwererenso.

Ndi zaka 20 zaukadaulo wopanga, Jinbin Valve imadziwika bwino popanga ndi kupanga ma valve a mafakitale kuphatikiza zipata zotseguka, ma valve a cone, ma valve a blind, ma air dampers, ma valve a gulugufe, ma valve a zipata ndi ma flap gates. Timapereka chithandizo chaukadaulo cha munthu payekha komanso ma valve opangidwa mwapadera kuti agwirizane ndi momwe makasitomala amagwirira ntchito. Chonde siyani funso lanu pansipa ngati muli ndi zofunikira, ndipo tidzayankha mkati mwa maola 24.
