Kodi Valavu ya Gulugufe ndi Chiyani?

Vavu ya gulugufe imatanthauza valavu yokhala ndi gawo lotseka (disiki ya valavu kapena mbale ya gulugufe) ngati diski, yomwe imazungulira mzere wa valavu kuti itsegule ndi kutseka. Imagwiritsidwa ntchito makamaka kudula ndi kukanda paipi. Gawo lotsegulira ndi kutseka valavu ya gulugufe ndi mbale ya gulugufe yooneka ngati diski yomwe imazungulira mzere wake womwe uli m'thupi la valavu kuti ikwaniritse cholinga chotsegula ndi kutseka kapena kulamulira.

1. Kapangidwe ka valavu ya gulugufe

Valavu ya gulugufe imapangidwa makamaka ndi thupi la valavu, mbale ya gulugufe, tsinde la valavu, mphete yotsekera ndi chipangizo chotumizira. Thupi la valavu ndi lozungulira, ndi bosi lozungulira pamwamba ndi pansi loyika tsinde la valavu. Valavu ya gulugufe imalumikizidwa kwambiri ndi payipi ndi flange; ngati kulumikizana kwa clamp kwagwiritsidwa ntchito, kutalika kwake kumakhala kochepa kwambiri. Tsinde la valavu ndi shaft yozungulira ya mbale ya gulugufe, ndipo kumapeto kwa shaft kumagwiritsa ntchito kapangidwe kotsekera bokosi lodzaza kuti lisatuluke. Mapeto apamwamba a tsinde la valavu amalumikizidwa mwachindunji ndi chipangizo chotumizira kuti atumize torque. Mbale ya gulugufe ndi gawo lotsegulira ndi kutseka la valavu ya gulugufe. Malinga ndi mtundu wolumikizira, imatha kugawidwa mu kulumikizana kwa flange ndi kulumikizana kwa clamp; malinga ndi njira yotumizira, imatha kugawidwa mu manual, gear transmission, pneumatic, hydraulic ndi electric.

Ngodya kuyambira pakutseguka kwathunthu mpaka kutseka kwathunthu kwa valavu ya gulugufe nthawi zambiri imakhala yochepera 90°. Vavu ya gulugufe ndi tsinde la gulugufe sizitha kudzitsekera zokha. Kuti mbale ya gulugufe ikhazikike, chochepetsera zida za nyongolotsi chiyenera kuyikidwa pa tsinde la valavu. Kugwiritsa ntchito chochepetsera zida za nyongolotsi sikungopangitsa mbale ya gulugufe kukhala ndi luso lodzitsekera yokha ndikuyimitsa mbale ya gulugufe pamalo aliwonse, komanso kumawonjezera magwiridwe antchito a valavu.

2. Mfundo yogwirira ntchito ya valavu ya gulugufe

Disiki ya valavu ndi diski. Kudzera mu kuzungulira kwa tsinde la valavu, diski ya valavu imazungulira 90° mkati mwa mpando wa valavu kuti itsegule ndi kutseka valavu. Imagwira ntchito yotseka mu payipi. Imathanso kusintha kayendedwe ka madzi. ??

Ubwino wa valavu ya gulugufe: kapangidwe kosavuta, kupepuka, kugwiritsa ntchito mosavuta, kutseka bwino.

3. Kugawa ma valve a gulugufe

Ma valve a gulugufe amatha kugawidwa m'ma valve atatu a gulugufe (Triple offset), ma valve a gulugufe ogwira ntchito bwino (omwe amatchedwanso ma valve a gulugufe awiri ozungulira), ndi ma valve a gulugufe apakati (omwe amatchedwanso ma valve a mpando wa gulugufe a rabara) malinga ndi kapangidwe kake.

Malinga ndi mawonekedwe otsekera, amatha kugawidwa m'magulu awiri: mtundu wofewa wotsekera ndi mtundu wolimba wotsekera (ma valavu a gulugufe otsekera amagawidwa m'magulu awiri otsekera a gulugufe ndi ma valavu a gulugufe otsekera achitsulo). Mtundu wofewa wotsekera nthawi zambiri umagwiritsa ntchito kutsekera kwa mphete ya rabara, ndipo mtundu wolimba wotsekera nthawi zambiri umagwiritsa ntchito kutsekera kwa mphete yachitsulo.

4. Mfundo zosankhika za ma valve a gulugufe

-Popeza kutayika kwa mphamvu ya ma valve a gulugufe ndi kwakukulu poyerekeza ndi ma valve a chipata ndi ma valve a mpira, ndi oyenera machitidwe a mapaipi omwe alibe zofunikira zochepetsera mphamvu yamagetsi.

-Popeza ma valve a gulugufe angagwiritsidwe ntchito polamulira kayendedwe ka madzi, ndi oyenera mapaipi omwe amafunikira kayendetsedwe ka madzi.

-Chifukwa cha zofooka za kapangidwe ka valavu ya gulugufe komanso zinthu zotsekera, sikoyenera kugwiritsa ntchito mapaipi otentha kwambiri komanso amphamvu kwambiri. Kutentha kwapadera kogwira ntchito kuli pansi pa 300°C ndipo kuthamanga kwapadera kuli pansi pa PN40.

-Popeza valavu ya gulugufe ili ndi kutalika kwa kapangidwe kafupi ndipo imatha kupangidwa kukhala mainchesi akulu, ndibwino kugwiritsa ntchito valavu ya gulugufe pamene kutalika kwa kapangidwe kake kukufunika kuti kakhale kochepa kapena valavu yayikulu (monga DN1000 kapena kupitirira apo).

-Popeza valavu ya gulugufe imatha kutsegulidwa kapena kutsekedwa pozungulira 90° yokha, ndibwino kugwiritsa ntchito valavu ya gulugufe pamene kutseguka ndi kutseka mwachangu kukufunika.

Chidule

Misika ya ma valve a gulugufe yakhala ikukula mofulumira m'zaka zaposachedwa, ndipo mndandanda wa ogulitsa ma valve a gulugufe wakhala ukusintha. Tikasankhafakitale ya vavu ya gulugufe, tifunika kuphatikiza zosowa zathu, monga mtundu, mtengo, utumiki ndi zina, kuti tisankhewopanga mavavu a gulugufezomwe zikukwaniritsa zofunikira zanu.
