Kulemera kwa avalavu ya butterflyndizofunikira pamapangidwe onse adongosolo. Zimakhudza kuyika, kukonza, komanso magwiridwe antchito onse. Amadziwika ndi mapangidwe ake ophatikizika komanso kuwongolera koyenda bwino, ma valve a butterfly ndi ofunikira pakugwiritsa ntchito kosiyanasiyana kuchokera kumankhwala amadzi kupita kumafuta ndi gasi.
1. Chidule cha Kulemera kwa Gulugufe Wavu.
Kulemera kwa vavu ya gulugufe kumatengera kuchuluka kwa zolemera zonse. Kulemera kwa valavu yagulugufe kumasiyanasiyana malinga ndi kapangidwe kake ndi kachitidwe ka gulugufe.
1.1 Mapangidwe Oyambira
A valavu ya butterflyimakhala ndi thupi la valve, disc, tsinde, mpando, ndi actuator. Thupi la valve ndilo thupi lalikulu, lomwe limayang'anira kulumikiza chitoliro cha chitoliro, kupanga chipika chotsekedwa, ndikukhala ndi zigawo zina. Diski imazungulira kuzungulira pakati, ndipo kusinthasintha kumeneku kumapangitsa kuti valavu itsegule kapena kutseka, motero imayendetsa kutuluka kwa madzi kapena mpweya. Tsinde la valve limagwirizanitsa diski ndi actuator, yomwe imatha kugwiritsidwa ntchito pamanja kapena yokha. Mpandowo umatsimikizira kutseka kolimba kuti asatayike.
Kufunika kwa Kulemera kwa Vavu
- Kukhala ndi malingaliro
Kulemera kwa vavu kumagwira ntchito yofunika kwambiri pakupanga dongosolo. Mphamvu yonyamula katundu wothandizira iyenera kuganiziridwa pakupanga. Ma valve olemera angafunike chithandizo chowonjezera, chomwe chimawonjezera zovuta za kukhazikitsa.
-Kukhazikitsa ndi kukonza
Mavavu opepuka nthawi zambiri amathandizira kukhazikitsa ndikuchepetsa ndalama zogwirira ntchito. Amafuna kusamalidwa pang'ono ndi chithandizo, kupangitsa kuti kukonzanso kukhale kosavuta komanso kothandiza. Kukonzekera kumeneku kungathe kuchepetsa nthawi yopuma komanso kuchepetsa ndalama zogwirira ntchito.
- Kuchita Bwino Kwambiri
Ma valve opepuka amatha kupereka nthawi yoyankha mwachangu. Zosankha zamapangidwe zimatha kukulitsa magwiridwe antchito, kuwonetsetsa kuti valavu ikukwaniritsa zofunikira zogwirira ntchito. Mwachitsanzo, mavavu agulugufe nthawi zambiri amakhala opepuka kuposa mavavu apachipata, kotero mavavu agulugufe amatha kuwongolera magwiridwe antchito amadzimadzi.
-Kuganizira za Mtengo
Kulemera kwa valve kumakhudza mtengo wake m'njira zingapo. Mavavu olemera kwambiri atha kubweretsa ndalama zambiri zotumizira ndi kusamalira. Kuphatikiza apo, zinthu zomwe zimagwiritsidwa ntchito popanga zimatha kukhudza mtengo wonse. Kusankha kulemera kwa valve yoyenera kungapulumutse ndalama zambiri, pogula koyamba komanso kukonza nthawi yayitali.

Kugawa ndi Mtundu
Mtundu wa valavu agulugufe zimakhudza kulemera kwake ndi kuyenerera kwa ntchito. Gome la kulemera kwa vavu agulugufe limayika valavu kukhala mitundu itatu ikuluikulu, iliyonse ili ndi mawonekedwe osiyanasiyana ndi ntchito.
Mtundu wa Wafer
Mavavu agulugufe wawafer amalumikizana mwamphamvu pakati pa flanges ndipo amangofunika mabawuti anayi okha, kutenga malo ochepa. Kapangidwe kameneka kamachepetsa kulemera, kumapangitsa mavavu ophatikizika kukhala abwino kwa ntchito pomwe zoletsa ndi zolemetsa ndizofunikira.
Mtundu wa Lug
Mavavu agulugufe a Lug amakhala ndi zoyika zopindika zomwe zitha kukhazikitsidwa pogwiritsa ntchito mabawuti, opanda mtedza. Kapangidwe kameneka kamapereka kukhazikika kowonjezereka komanso kuwongolera bwino, makamaka pamakina omwe amafunikira kusokoneza pafupipafupi. Kulemera kwa mavavu agulugufe kumadalira zinthu monga kapangidwe kazinthu ndi kukula kwake, zomwe zimakhudzanso mtengo ndi magwiridwe antchito awo.
Mtundu wa Flanged
Mavavu agulugufe a Flanged amapereka kulumikizana kotetezeka komanso kotetezeka kumayendedwe amapaipi. Mapangidwe awo amaphatikizapo ma flanges omwe amangiriridwa mwachindunji ku chitoliro, chomwe chimapangitsa kukhazikika ndi kukana kutayikira. Ngakhale ma valve opangidwa ndi flanged amakhala olemetsa, kulimba kwawo ndi mphamvu zake zimawapangitsa kukhala oyenera kugwiritsa ntchito mphamvu zambiri.
Chidule
Kumvetsetsa kulemera kwa mavavu agulugufe ndikofunikira kuti mukwaniritse mapangidwe ndi magwiridwe antchito. Kulemera kwa vavu kungakhudze kuyika, kukonza, komanso kugwira ntchito bwino. Poganizira kulemera kwa vavu, mainjiniya amatha kupanga zisankho zodziwika bwino zomwe zimayang'anira magwiridwe antchito, kulimba, ndi mtengo wake. Izi zimatsimikizira kuti valavu yosankhidwa ikukwaniritsa zofunikira zogwiritsira ntchito.
"Kusankhidwa koyenera kwa ma valve kumaphatikizapo kufufuza zofunikira zomwe zimagwiritsidwa ntchito poyang'ana kukula kwa valve, mapangidwe a dongosolo, katundu wakuthupi, kuyika ndi kukonza zofunikira, mtengo wamtengo wapatali ndi kutsata malamulo."
