Ma valve a butterfly ndi amodzi mwa ma valve omwe amagwiritsidwa ntchito kwambiri powongolera kuyenda. Njira yake yayikulu yoyendetsera ndikuzungulira mbale ya valve ndikuwongolera kuthamanga ndi kuthamanga kwamadzi mupaipi kudzera mutsinde la singano pakatikati pa mbale ya valve. Zotsatirazi ndizofotokozera mwatsatanetsatane ndondomeko yogwirira ntchito ya butterfly valve.

Kupanga valavu ya butterfly pamanja

Buku lagulugufe valavu makamaka wopangidwa ndi valavu thupi, valavu shaft, valavu mbale, mphete kusindikiza, actuating chipangizo, etc. The valavu thupi ndi mbali yaikulu ya buku gulugufe valavu, kulumikiza malekezero onse a payipi; Mtsinje wa valve ndi gawo lofunikira lothandizira mbale ya valve, kulumikiza thupi la valve ndi mbale ya valve; Pulati ya valve imagwirizanitsa shaft ya valve ndikuwongolera kuthamanga ndi kuthamanga mu chitoliro ndi kuzungulira kwake. Mphete yosindikizira ili mu poyambira kuzungulira mbale ya valavu ndipo imakanikizidwa kuti asatayike pokhudzana ndi thupi la valve. Kusintha kwa valavu ya butterfly kumayendetsedwa ndi chipangizo chothandizira (chogwirira, zida, mota, zida za pneumatic, etc.).

Mfundo yogwira ntchito ya valavu ya butterfly

Pamene valavu ya butterfly yatsegulidwa kwathunthu, mbale ya valve ndi njira ya valavu imakhala yofanana, ndiye kuti madzi amatha kudutsa mutoliro momasuka. Pamene valavu ya gulugufe yamanja imatembenuzidwa ngati chipangizo chosuntha (kawirikawiri kusinthasintha kwa madigiri 90), mbale ya valve imayenda motsatira nsonga ya shaft ya valve kuti iwononge kukula kwa njira yamadzimadzi mu chitoliro.

Pamene mbale ya valve imayendetsedwa ku madigiri a 90, njirayo imatsekedwa kwathunthu, ndipo valve imatsekedwa ndipo madzi sangathe kudutsa. Ngati valavu ili yotseguka pang'ono, madzi a m'chitoliro sangathe kudutsa mumsewu wonse chifukwa mbale ya valve imapendekera mkati mwa chitoliro, koma imatha kudutsa mipata yopapatiza pakati pa njirazo.

Kutseka kwa mbale ya valve nthawi zambiri kumachitika pogwiritsa ntchito kukakamiza ku mbale ya valve. Pamene valavu ya butterfly yatsekedwa, mbale ya valve imakanizidwa ndi thupi. Chifukwa cha mphete yosindikizira yomwe imayikidwa pakati pa zigawo ziwirizi, mphete yosindikizira imalepheretsa bwino kutuluka kwamadzimadzi pamene valve yatsekedwa kwathunthu.

Kagwiritsidwe ntchito ka mavavu agulugufe amanja

Mitundu yogwiritsira ntchito ma valve a butterfly ndi yotakata kwambiri, kuphatikizapo mankhwala a madzi, mankhwala, mafuta, gasi ndi zina. Malo ogwirira ntchito m'maderawa ali ndi zofunikira zapamwamba za ma valve, monga kuthamanga kwapamwamba, kutentha kwakukulu, corrosion, etc., ndi ma valve a butterfly a manual amagwira ntchito bwino m'maderawa ndipo amakhala ndi moyo wautali kuposa mitundu ina ya valve.

Ubwino wa mavavu agulugufe amanja

Mavavu agulugufe amanja ali ndi mwayi wapadera chifukwa chogwiritsa ntchito zida zatsopano ndi zida. Izi zikuphatikizapo: kuthamanga kwachangu, koyenera kutsata ndondomeko yeniyeni ya kayendedwe ka mapaipi; Kusindikiza kwabwino, kumatha kupewa kuchitika kwa kutayikira kwamadzimadzi, kupewa kuipitsidwa kwa mapaipi; Kukonza kosavuta, zigawo zosavuta, zosavuta kusintha zisindikizo ndi zina zotero.

Mwachidule, ntchito ya mavavu agulugufe pamanja potengera kupanikizika, kuwongolera koyenda ndi kutsika kwamadzimadzi ndizabwino kwambiri, ndipo ndizoyenera kugwiritsa ntchito zosiyanasiyana m'magawo ndi magawo osiyanasiyana. Kumvetsetsa mozama ndikumvetsetsa mfundo yogwirira ntchito ndi kapangidwe ka valavu ya butterfly kungapereke thandizo linalake kwa ogwiritsa ntchito kusankha valavu yagulugufe yoyenera kwambiri, kukonza ndi kugwiritsa ntchito valavu ya butterfly.
