Mu msonkhano wa Jinbin, chiwerengero chachikulu chama valve a globeakuunika komaliza. Malinga ndi zomwe makasitomala amafuna, makulidwe awo amachokera ku DN25 mpaka DN200. (2 inch globe valve)

Monga valavu wamba, valavu yapadziko lonse lapansi imakhala ndi izi:

1.Ntchito yabwino kwambiri yosindikiza: Chisindikizo chapachimake chimakhala ndi mgwirizano wolimba pakati pa diski ya valve ndi mpando wa valve. Ikatsekedwa, diski ya valve imakanikiza pampando wa valve pansi pa kupanikizika, kukwaniritsa kudula kolimba. Ndizoyenera kugwiritsa ntchito pomwe kutayikira kwapakati kumafunika kupewedwa (monga mapaipi a gasi ndi nthunzi).

2.Ntchito yodziwika bwino yoyendetsera ntchito: Disiki ya valve imakwera ndikugwera pamphepete mwa tsinde la valve, ndipo kuthamanga kwa kayendedwe kake kakhoza kusinthidwa bwino poyang'anira digiri yoyamba. Kuthamanga kumasintha bwino kuchokera kutseguka kwathunthu mpaka kutsekedwa kwathunthu, ndikupangitsa kuti ikhale yoyenera pazochitika zomwe zimafuna kuyendetsa bwino (monga kusintha kwa kutentha kwa machitidwe otenthetsera).

3.Kukana kwakukulu kothamanga: Sing'anga imafunika kutembenuka ndi kutuluka pambuyo podutsa pampando wa valve, ndi njira yowonongeka. Kutaya kwamphamvu kumakhala kwakukulu kuposa ma valve owongoka monga ma valve a zipata. Choncho, si yoyenera mapaipi omwe ali ndi kutuluka kwakukulu ndi zofunikira zochepa zokana (monga chitoliro chachikulu cha madzi).

Kuyika kwa 4.Kuyika njira: Iyenera kukhazikitsidwa motsatira ndondomeko ya "low in, high out" (sing'anga imayenda kuchokera pansi pa diski ya valve), kuonetsetsa kuti diski ya valve imathandizidwa kusindikiza ndi kuthamanga kwapakati pamene kutsekedwa, ndipo ntchitoyo ndi yovuta. Kuyiyika mobwerera kumapangitsa kuti chisindikizo chilephereke komanso kugwira ntchito movutikira.

5.Nkhani zambiri zomwe zimagwiritsidwa ntchito: Zitha kugwiritsidwa ntchito pazinthu zoyera monga madzi, nthunzi, mafuta opangira mafuta, ndi gasi, koma sizoyenera kuvina kwambiri kapena zofalitsa za granular (monga zimatha kuvala kusindikiza pamwamba ndikuwononga ntchito yosindikiza).

Kutengera mawonekedwe awa, ma valve oyimitsa amagwiritsidwa ntchito kwambiri pazinthu zomwe zimafuna kutsekedwa mwamphamvu komanso kuwongolera bwino:

1. Njira yoperekera madzi ndi ngalande: Monga valavu yoyendetsera mapaipi anthambi, imadula kapena kuwongolera kuchuluka kwa madzi kuti iwonetsetse kuwongolera kwa mapaipi amtundu uliwonse.

2. Dongosolo la nthunzi: Chepetsani kuchuluka kwa nthunzi kapena sinthani kuchuluka kwa mapaipi a nthunzi m'mafakitale, ndipo gwiritsani ntchito malo ake osindikizira kuti mupewe kutayikira kwa nthunzi ndi kutaya mphamvu.

3. Makampani a petrochemical: Ponyamula mafuta osakanizika, zosungunulira ndi zoulutsira zina, kuchuluka kwamayendedwe kumayendetsedwa ndikusintha digirii yotsegulira kuti ikwaniritse zofunika kudyetsa chipangizocho.

4. Makina otenthetsera ndi mpweya: Sinthani kuyenda kwamadzi otentha kapena firiji kuti muzitha kuwongolera bwino kutentha kwachipinda ndikuwonjezera mphamvu yogwiritsira ntchito mphamvu.

Mapaipi a mpweya ndi mpweya: Monga valavu yotsekera chitetezo, imatseka mwachangu panthawi yokonza kapena zolakwika pofuna kupewa kutayikira kwapakatikati komanso ngozi zomwe zingachitike.

Ndi ubwino wa kusindikiza kodalirika komanso kusinthasintha, valavu yapadziko lonse lapansi yakhala chigawo chachikulu mu machitidwe a mapaipi omwe amaphatikiza ntchito zodula ndi kuwongolera. Ndiwosasinthika makamaka muzochitika zokhala ndi ma diameter apakati ndi ang'onoang'ono komanso zofunika kwambiri pakusindikiza ndi kuwongolera. (Globe Valve Price)
