Mu malo ochitira masewera a Jinbin, ma valve awiri a gulugufe a wafer omwe kasitomala amawasankha akuyang'aniridwa komaliza. Kukula kwa wafervalavu ya gulugufendi DN800, yokhala ndi thupi la valavu yopangidwa ndi chitsulo chosungunuka ndi mbale ya valavu yopangidwa ndi EPDM, zomwe zikugwirizana ndi momwe kasitomala amagwirira ntchito. 

Ubwino waukulu wa ma valve a gulugufe a EPDM wafer ndi wodziwika bwino, kuphatikiza magwiridwe antchito komanso ndalama zochepa.

Ma valve plate a EPDM ali ndi kuchira kokongola komanso kukana nyengo, ndi kutentha kwakukulu kuyambira -40℃ mpaka 120℃. Ali ndi kupirira kwakukulu ku zinthu zofooka monga ma acid, alkalis, ndi zimbudzi, zomwe zimapangitsa kuti zisamatuluke. Kapangidwe ka DN800 large diameter, kuphatikiza ndi valavu ya gulugufe yamtundu wa wafer, ili ndi mphamvu yolimba yoyendera, ikukwaniritsa zofunikira zoyendera za zinthu zoyendera komanso kuchepetsa kugwiritsa ntchito mphamvu kwa netiweki ya mapaipi. 

Kapangidwe ka valavu ya gulugufe ka wafer kamachepetsa kulemera ndi 30% poyerekeza ndi valavu ya gulugufe yopindika, sikufuna zida zazikulu zokwezera, ndikosavuta kuyika ndikuchotsa mbale ya valavu, ndipo imakhala ndi ndalama zochepa zosamalira pambuyo pake. Zipangizo za EPDM sizimakalamba komanso kung'ambika. Zikaphatikizidwa ndi ma tsinde a valavu yachitsulo chosapanga dzimbiri, sizimawonongeka mosavuta m'malo okhala ndi mchenga ndi zinthu zolimba zopachikidwa. Nthawi yake yogwira ntchito ndi yayitali nthawi ziwiri kapena zitatu kuposa ya mbale wamba za valavu ya rabara. Kuphatikiza apo, m'magawo akuluakulu, ndalama zake zopangira zimakhala zotsika ndi 40% kuposa za ma valavu a mpira ndi ma valavu a chipata, ndipo ndalama zoyikira ndi kugwiritsa ntchito ndi kukonza zimachepetsedwanso. Zimaphatikiza magwiridwe antchito apamwamba ndi magwiridwe antchito okwera mtengo. 

Kugwiritsa ntchito kwake kothandiza kumakhudza zochitika zazikulu m'mafakitale osiyanasiyana:

Mu ntchito zoperekera madzi ndi madzi m'matauni, ndi yoyenera mapaipi akuluakulu a maukonde operekera madzi m'mizinda, mapaipi olowera ndi otulutsira madzi m'malo oyeretsera zinyalala, ndi makina otulutsira zinyalala m'matanki oyeretsera zinyalala. Imatha kupirira kuwonongeka kwa zinthu zachilengedwe ndi zinyalala m'matanki oyeretsera zinyalala ndipo imatsekedwa kuti isatuluke. Mu ntchito yoyeretsa madzi, EPDM ingagwiritsidwe ntchito potsuka mapaipi a matanki oyeretsera m'malo oyeretsera zinyalala m'madzi ndi makina obwezeretsanso madzi. Epdm si poizoni komanso yoteteza chilengedwe, ndipo imakwaniritsa miyezo yaukhondo ya madzi akumwa. 

Ndi yoyenera mapaipi onyamula ma acid ndi alkali ndi zinyalala za mankhwala m'makampani opanga mankhwala, ndipo imatha kupirira dzimbiri la ma acid achilengedwe, mchere wa alkali ndi zina zotero. Mu HVAC ndi kutentha kwapakati, ndi yoyenera maukonde otenthetsera okhala m'mizinda ndi machitidwe oyendera madzi m'mapaki akuluakulu a mafakitale. Ili ndi kukana kotsika kwa madzi komanso kukana kutentha koyenera, zomwe zimapangitsa kuti kutentha kusinthe bwino. Mu mafakitale amagetsi ndi zitsulo, ingagwiritsidwe ntchito m'mapaipi ozungulira madzi amagetsi ndi machitidwe ozizira amadzi achitsulo, ndipo imatha kupirira kuwonongeka kwa madzi ozungulira kutentha kwambiri ndi zinyalala zamafakitale. Mu ulimi ndi kusamalira madzi, ndi yoyenera mapaipi akuluakulu oyendetsera madzi m'madera akuluakulu othirira ndi mapaipi otulutsa madzi osefukira m'malo osungira madzi. Ndi yolimba ku ukalamba wa ultraviolet, yosinthika ku malo ovuta akunja, ndipo imakwaniritsa kufunikira kwa kunyamula madzi ambiri. 

Monga wopanga ma valve wokhala ndi zaka 20 zakuchitikira, Jinbin Valve imapanga ma valve osiyanasiyana osungira madzi ndi zitsulo, kuphatikiza ma valve agulugufe akuluakulu, ma valve a zipata, ma penstock gates omangiriridwa pakhoma, ma channel gates, air dampers, louvers, discharge valves, conical valves, knife gate valves, ndi ma valve a zipata, ndi zina zotero. Timasintha ndikupanga malinga ndi zosowa za makasitomala, zomwe zimakwaniritsa bwino momwe ntchito ikuyendera. Ngati muli ndi zofunikira zina, chonde titumizireni uthenga pansipa. Mudzalandira yankho mkati mwa maola 24!
