Momwe mungasankhire valavu yachitsulo chosapanga dzimbiri?

Valovu yachitsulo chosapanga dzimbiri ndi valavu yokhayokha yokhala ndi mitundu yambiri komanso mawonekedwe.Mtundu wamtunduwu umagwiritsidwa ntchito makamaka poletsa kubweza kwa sing'anga, kusinthasintha kwa mpope ndi galimoto yake yoyendetsa, komanso kutulutsa sing'anga mumtsuko.Ikhoza kugwiritsidwa ntchito zosiyanasiyana pa mzere wapakatikati.Ndiye tingasankhe bwanji valavu yachitsulo chosapanga dzimbiri?Kodi tiyenera kulabadira chiyani?

1. Nthawi zambiri amalangizidwa kuti ogwiritsa ntchito asankhe zitsulo zosindikizidwa zolimba zotchinga ma valve kuti atsimikizire kuti ma valve ofufuza a wafer amakhala ndi moyo wautali wautumiki, kutentha kwapamwamba kwa ntchito, ndi ntchito yosindikiza yofanana.

2. Ngati kukula mwadzina ndi kwakukulu kuposa kapena kofanana ndi DN100 (NPS4), ndi bwino kusankhaH76 mtundu wapawiri chimbale swing chowotcha cheke valavu, yomwe ingachepetse bwino kutaya kwa madzimadzi kukana kwa valve yowunika;kukula mwadzina ndi kochepa kapena kofanana ndi DN80 (NPS3), ndipo kusankha H71 mtundu wokweza valavu ndiyoyenera.

3. TheH71 lift mtundu wafer check valveyokhala ndi kukula mwadzina kochepera kapena kofanana ndi DN100 (NPS) nthawi zambiri samapangidwa chifukwa cha kapangidwe kake kophatikizana ndikuganizira za kukonza ndi kupanga.Ndibwino kuti ogwiritsa ntchito asankhe zitsulo zosapanga dzimbiri zonyamulira mtundu wa wafer check valves.valavu.

4. Kuphatikiza pa mtundu wophwanyidwa, chitsulo chosapanga dzimbiri chopanda chitsulo cha double disc swing check valve chilinso ndi mtundu wa lug ndi mtundu wa flange.Ngati wogwiritsa ntchito alibe zofunikira zapadera, mawonekedwe apangidwe nthawi zambiri amapangidwa ndi kampani yathu molingana ndi miyezo wamba.Ma valve ena awiri oyendetsa ma disc amatha kupangidwa ndi mawonekedwe awiri a flange (mtundu wa H46).

5. The lug flange ya lug double flap swing check valve imangogwira ntchito yoyika, ndipo thumba silikhala ndi mphamvu ya bawuti, kotero makulidwe a lug flange sanapangidwe molingana ndi makulidwe a flange wamba, nthawi zambiri. The lug flange Kukhuthala kwake ndi kochepa poyerekeza ndi ma flanges wamba.The flange ya double flange connection double disc swing check valve imakhala ndi mphamvu ya bawuti, ndipo makulidwe a flange amapangidwa molingana ndi muyezo wa flange.

6. Ma valve okwera amtundu wonyamulira omwe ali ndi zokakamiza mwadzina PN10, PN16, PN25 ndi PN40 ali ndi mndandanda wautali wamapangidwe awiri.Mtengo wama valavu amfupi amfupi ndiwotsika, koma ma gaskets osagwirizana ndi osagwirizana angafunike pakati pa valavu ya cheke ndi payipi ya payipi.Ngati ma valavu amtundu wautali atagwiritsidwa ntchito, ma gaskets okhazikika a flange amatha kukonzedwa.
