Momwe Mungasankhire Valavu Yabwino Ya Mphepo Yam'madzi

Kusankha choyeneravalavu yamkunthopakuti sitima yanu ndi yofunika kwambiri kuti sitimayo ikhale yotetezeka komanso yogwira ntchito bwino, makamaka popewa kulowa kwa madzi a m'nyanja nthawi ya nyengo yoipa. Nazi mfundo zofunika kuziganizira posankha valavu yoyenera yamkuntho.

1. Mtundu wa Vavu ndi Kapangidwe kake

Ma valve amphepo amabwera m'mitundu yosiyanasiyana komanso mawonekedwe, iliyonse yoyenera ntchito zinazake

• Chitsanzo Cholunjika (Choyimirira): Yabwino kwambiri poyikapo mapaipi omwe amayenda molunjika.
• Chitsanzo cha Ngodya: Yoyenera mapaipi omwe amasintha njira, nthawi zambiri pa ngodya ya madigiri 90.

Sankhani kasinthidwe komwe kakugwirizana ndi kapangidwe ka mapaipi a sitima yanu kuti muwonetsetse kuti ikugwira ntchito bwino.

2. Kukula ndi Miyezo Yolumikizira

Onetsetsani kuti kukula kwa valavu kukugwirizana ndi kukula kwa payipi yanu. Kukula kofanana kumayambira pa DN50 mpaka DN300. Kuphatikiza apo, onetsetsani kuti kulumikizana kwa flange ya valavu kukugwirizana ndi miyezo ya makina anu, monga ma flange a PN16 kapena JIS-5K/JIS-10K.

3. Kusankha Zinthu

Zipangizo ziyenera kusankhidwa kutengera malo ogwirira ntchito

• Thupi: Chitsulo chopangidwa ndi ductile kapena bronze choteteza dzimbiri.
• Disiki ndi TsindeChitsulo cha mkuwa kapena chosapanga dzimbiri chopirira mavuto a m'nyanja.
• Zisindikizo: NBR (Nitrile Butadiene Rubber) kuti igwire bwino ntchito komanso kuti ikhale yolimba.

Kusankha zipangizo zoyenera kumawonjezera moyo wautali komanso kudalirika kwa valavu.

4. Kuchuluka kwa Kupanikizika ndi Kutentha

Tsimikizirani kuti kupanikizika ndi kutentha kwa valavu zikugwirizana ndi zofunikira za makina anu. Mwachitsanzo, mavalavu ena amphepo amayesedwa kuti agwire ntchito bwino kwambiri mpaka 4 bar ndipo kutentha kwake kumayambira -10°C mpaka 60°C.

5. Njira Yotsekera

Ma valve amphepo nthawi zambiri amakhala ndi njira yotsekera kuti asabwererenso

• Gudumu lamanja: Imalola kugwira ntchito ndi manja kutsegula kapena kutseka valavu ngati pakufunika.
• Kutseka KokhaMa valve ena amapangidwira kuti azitseka okha pansi pa mikhalidwe ina.

Sankhani njira yomwe ikugwirizana ndi zomwe mumakonda pa ntchito yanu komanso njira zodzitetezera.

6. Kutsatira Malamulo ndi Chitsimikizo

Onetsetsani kuti valavu yamkuntho ikutsatira miyezo ndi ziphaso zamakampani apamadzi, monga DIN 87101 Fomu B kapena mabungwe oyenera monga Lloyd's Register kapena DNV. Kutsatira malamulo kumatsimikizira kuti valavuyo ikukwaniritsa miyezo yachitetezo ndi khalidwe.

7. Kukonza ndi Kuyesa

Sankhani ma valve omwe ndi osavuta kusamalira komanso kuyesa. Kukonza nthawi zonse, kuphatikizapo kuyesa kwa hydrostatic, ndikofunikira kuti muwonetsetse kuti valavuyo ndi yolimba komanso yolimba.
