Ngati mukukayikirabe kusankha ma valve a chipata chachitsulo chopangidwa ndi chitsulo kapena ma valve a chipata chachitsulo chopangidwa ndi chitsulo chopangidwa ndi chitsulo (WCB), chonde onani fakitale ya ma valve ya zfa kuti muwone kusiyana kwakukulu pakati pawo.

1. Kupangira ndi kuponya ndi njira ziwiri zosiyana zokonzera.

Kuponya: Chitsulocho chimatenthedwa ndi kusungunuka kenako chimathiridwa mu nkhungu yamchenga kapena nkhungu. Pambuyo pozizira, chimauma kukhala chinthu. Mabowo a mpweya amapangidwa mosavuta pakati pa chinthucho.
Kupangira: Kugwiritsa ntchito njira monga kuponya chitsulo pa kutentha kwambiri kuti chitsulocho chikhale chogwirira ntchito chokhala ndi mawonekedwe ndi kukula kwina mu pulasitiki, ndikusintha mawonekedwe ake enieni.

2. Kusiyana kwa magwiridwe antchito pakati pa ma valve a chipata chopangidwa ndiMa valve a chipata cha WCB

Pakupangira, chitsulocho chimasinthidwa ndi pulasitiki, zomwe zimapangitsa kuti chikhale choyenga bwino, kotero nthawi zambiri chimagwiritsidwa ntchito popanga zinthu zofunika zopanda kanthu. Kupangira zinthu kumakhala ndi zofunikira pa zipangizo zomwe ziyenera kukonzedwa. Kawirikawiri, chitsulo chopangidwa ndi chitsulo, aluminiyamu, ndi zina zotero zimakhala ndi zinthu zabwino zopangira zinthu. Kupangira zinthu sikuli ndi ubwino wambiri wopangira zinthu, koma kumatha kupanga zinthu zokhala ndi mawonekedwe ovuta, kotero nthawi zambiri kumagwiritsidwa ntchito popanga zinthu zopanda kanthu zomwe sizifuna zinthu zambiri zamakanika.

2.1 Kupanikizika

Chifukwa cha kusiyana kwa zinthu zakuthupi, mavavu achitsulo opangidwa amatha kupirira mphamvu zazikulu zogunda, ndipo kupangika kwawo, kulimba kwawo ndi zinthu zina zamakanika ndizokwera kuposa zaMa valve a WCBChifukwa chake, ingagwiritsidwe ntchito pamavuto apamwamba ogwirira ntchito. Ma valavu achitsulo opangidwa ndi chitsulo omwe amagwiritsidwa ntchito kwambiri ndi awa: PN100; PN160; PN250; PN320; PN400, 1000LB ~ 4500LB. Ma valavu a WCB omwe amagwiritsidwa ntchito kwambiri ndi awa: PN16, PN25, PN40, 150LB ~ 800LB.

2.2 M'mimba mwake dzina

Popeza njira yopangira zinthu imakhala ndi zofunikira kwambiri pa nkhungu ndi zida, m'mimba mwake mwa ma valve opangidwa nthawi zambiri amakhala pansi pa DN50.

2.3 Mphamvu yoletsa kutuluka kwa madzi

Malinga ndi njira yokhayo, kuponya kumatha kutulutsa dzenje panthawi yokonza. Chifukwa chake, poyerekeza ndi njira yopangira, mphamvu yopewera kutuluka kwa mavavu opangidwa siili yabwino ngati ya mavavu opangidwa.
Chifukwa chake, m'mafakitale ena omwe ali ndi zofunikira zambiri zopewera kutayikira kwa madzi, monga gasi, gasi wachilengedwe, mafuta, mankhwala ndi mafakitale ena, ma valve achitsulo opangidwa ndi chitsulo akhala akugwiritsidwa ntchito kwambiri.

2.4 Maonekedwe

Ma valve a WCB ndi ma valve achitsulo chopangidwa ndi chitsulo chopangidwa ndi chitsulo ndi osavuta kuwasiyanitsa ndi mawonekedwe ake. Kawirikawiri, ma valve a WCB amawoneka ngati asiliva, pomwe ma valve achitsulo chopangidwa ndi ...

3. Kusiyana kwa magawo ogwiritsira ntchito

Kusankha kwapadera kwa mavavu a WCB ndi mavavu achitsulo opangidwa ndi chitsulo kumadalira malo ogwirira ntchito. Sizingatheke kufotokozedwa momveka bwino kuti ndi minda iti yomwe imagwiritsa ntchito mavavu achitsulo opangidwa ndi minda iti yomwe imagwiritsa ntchito mavavu a WCB. Kusankha kuyenera kutengera malo ogwirira ntchito. Kawirikawiri, mavavu a WCB sagonjetsedwa ndi asidi ndi alkali ndipo angagwiritsidwe ntchito pa mapaipi wamba okha, pomwe mavavu achitsulo opangidwa ndi chitsulo amatha kupirira kuthamanga kwambiri ndipo angagwiritsidwe ntchito m'mafakitale ena omwe ali ndi kutentha kwambiri, monga magetsi ndi mafakitale a mankhwala. Valavu ya kalasi.

4. Mtengo

Kawirikawiri, mtengo wa ma valve achitsulo opangidwa ndi chitsulo ndi wokwera kuposa wa ma valve a WCB.
