Kupititsa patsogolo liwiro la kuyankha kwamakina: Kuwunika kwanthawi yeniyeni kwa ma valve amagetsi a flange

M'makina a mapaipi a mafakitale, ma valve a magetsi a flange globe amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana chifukwa chogwira ntchito bwino komanso kusindikiza kodalirika. Pakati pawo, zizindikiro zenizeni za nthawi yeniyeni ya ma valve ndi chimodzi mwa zizindikiro zawo zofunika kwambiri, zomwe ziri zofunika kwambiri pakuwongolera liwiro la kuyankha kwa dongosolo ndikuwonetsetsa kuti zopanga zikuyenda bwino.

Choyamba, tiyeni tifufuze momwe ma valve amagetsi a flange amapangidwira. Vavu yamtunduwu imakhala ndi zigawo monga thupi la valavu, chivundikiro cha valve, chimbale cha valve, tsinde la valavu, mphete yosindikiza, ndi actuator yamagetsi. Pakati pawo, thupi la valve ndilo gawo lalikulu la valve, lomwe nthawi zambiri limagwirizanitsidwa ndi payipi kudzera mu mgwirizano wa flange. Chophimba cha valve chimakwirira pamwamba pa thupi la valve, kupereka chitetezo ku tsinde la valve. Disiki ya valve ndi chigawo chofunikira kwambiri chokwaniritsa kusindikiza, chomwe chili mkati mwa thupi la valve ndipo chimakwaniritsa kusindikiza pokhudzana kwambiri ndi mpando wa valve. Tsinde la valavu ndi gawo lofunikira lomwe limagwirizanitsa magetsi oyendetsa magetsi ndi disc valve. Imatumiza mphamvu ya actuator ku diski ya valve, kukwaniritsa kutsegula ndi kutseka kwa valve. Mphete yosindikiza imagwiritsidwa ntchito kupititsa patsogolo kusindikiza kwa valve ndikuletsa kutayikira kwapakati. Pomaliza, ma actuators amagetsi ndiye gwero lamphamvu lamagetsi oyendetsa ma valve, omwe amatha kukhala ma mota amagetsi, pneumatic kapena hydraulic actuators, ndi zina zambiri.

Kenako, tisanthula mfundo yogwirira ntchito ya valavu yamagetsi yamagetsi ya flange. Pamene choyendetsa magetsi chilandira chizindikiro chowongolera, chimayendetsa tsinde la valve kuti lisunthire mmwamba ndi pansi. Pamene tsinde la valve likuyenda, diski ya valve idzakweranso kapena kugwa moyenerera. Pamene disc ya valve ikukwera ndikusiya mpando wa valve, valve imatsegula ndipo sing'anga imatha kudutsa; Pamene diski ya valve imatsika ndikuyandikira pafupi ndi mpando wa valve, valve imatseka ndipo kutuluka kwa sing'anga kumadulidwa. Pochita izi, mphete yosindikizira imagwira ntchito yofunika kwambiri powonetsetsa kuti valavu isadutse ikatsekedwa. Kuphatikiza apo, kuwongolera kolondola kwakuyenda kumatha kupezedwa mwa kusintha kutalika kwa sitiroko ya actuator.

Mawonekedwe amagetsi amagetsi a flange globe akuwonetsedwa makamaka pazinthu izi:

1. Kuphatikizika kwambiri: Zigawo zazikulu za valavu zimaphatikizidwa mu thupi la valve, zomwe zimapangitsa kuti mawonekedwe a valve agwirizane ndipo amakhala ndi malo ochepa.

2. Zosavuta kugwiritsa ntchito: Zoyendetsedwa ndi makina opangira magetsi, zimakhala zosavuta kugwira ntchito ndipo zimakhala ndi liwiro lofulumira. Ogwiritsa ntchito amangofunika kutumiza malangizo kudzera mu dongosolo lowongolera kuti akwaniritse kuwongolera kwakutali.

3. Kuchita bwino kusindikiza: Zida zosindikizira zapamwamba komanso zomangira zomangidwa bwino zimagwiritsidwa ntchito kuti zitsimikizire kuti valve ikhoza kukhala ndi zotsatira zabwino zosindikizira pansi pa ntchito zosiyanasiyana.

4. Chitetezo ndi kudalirika: Valavu yamagetsi ya flange globe ili ndi njira zambiri zotetezera, monga chitetezo chochulukirapo, chitetezo cha kutayikira, ndi zina zotero, kuonetsetsa kuti zipangizozi zikugwira ntchito bwino komanso zodalirika.

5. Kugwiritsidwa ntchito kwakukulu: Chifukwa cha kugwiritsa ntchito kugwirizana kwa flange, valavu imatha kugwirizanitsa mosavuta ndi zigawo zina za mapaipi okhudzana ndi flange, kuti zikhale zoyenera kumadera osiyanasiyana a mafakitale.

Mawonekedwe a nthawi yeniyeni ya ma valve a magetsi a flange globe amawonekera makamaka pakuyankha kwawo mwachangu komanso kuwongolera kolondola. Chifukwa chogwiritsa ntchito ma actuators amagetsi ngati magwero amagetsi, ma valve amatha kukwaniritsa kuyankha mwachangu kwa millisecond, zomwe ndizofunikira kwambiri pamikhalidwe yomwe imafunikira kutseka mwachangu kapena kuwongolera kuyenda. Pakalipano, pophatikizana ndi machitidwe amakono olamulira, kuwongolera molondola kwa kutsegula kwa valve kungathe kupezedwa, potero kukwaniritsa zofunikira zenizeni zoyendetsera kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake.

Mwachidule, ma valve a magetsi a flange globe amagwira ntchito yofunika kwambiri pamapaipi a mafakitale chifukwa cha mfundo zawo zogwirira ntchito komanso mawonekedwe ake apadera. Kumvetsetsa mfundo zake zogwirira ntchito ndi mawonekedwe ake kumatithandiza kusankha bwino ndikugwiritsa ntchito valavu iyi, potero kuonetsetsa chitetezo, mphamvu, ndi kudalirika kwa kupanga mafakitale.
