Ma valve ogulitsa mafakitale osiyanasiyana ali ndi ntchito zosiyanasiyana.Ma valve ena amagwiritsidwa ntchito kuti asinthe kayendedwe kake, ena amagwiritsidwa ntchito poyenda ndi kudula, ndipo ena amagwiritsidwa ntchito kusintha njira yamadzimadzi.

Pakalipano, ma valve a mpira ndi ma valve a pakhomo ndi awiri omwe amagwiritsidwa ntchito kwambiri.M'nkhaniyi, tikuwonetsani kusiyana pakati pa mfundo zogwirira ntchito ndi kugwiritsa ntchito.Ndikuyembekeza kukuthandizani kumvetsetsa ndikusankha valve.

Kodi avalavu ya mpira?

Valve ya mpira ndi mtundu wa valve yozungulira kotala.Pali gawo mkati mwa thupi la valve.Chigawocho chimazungulira kotala ndi tsinde la valve kuti mutsegule kapena kutseka valavu.Mkati mwa chigawocho muli dzenje, zomwe zimapangitsa kuti madzi azitha kuyenda.

Malingana ndi mapangidwe, valavu ya mpira ikhoza kugawidwa mu njira ziwiri, njira zitatu kapena zinayi za mpira, zomwe zimagwiritsidwa ntchito pozungulira, kudula, kusintha kayendedwe ka kayendedwe ka sing'anga, confluence ndi divergence.

Ma valve a mpira nthawi zambiri amagwiritsidwa ntchito m'mafakitale otsika.Ngati mukufuna kuzigwiritsa ntchito pamakampani othamanga kwambiri, muyenera kusintha valavu ya mpira yomwe imatha kupirira kuthamanga kwambiri.

Vavu ya mpira imatha kupangidwa ndi pulasitiki, mkuwa, chitsulo chosapanga dzimbiri kapena chitsulo cha carbon.

Chifukwa cha kukula kochepa kwa valve ya mpira, idzakhala yoyenera kugwiritsidwa ntchito m'mapaipi ang'onoang'ono, monga makampani opangira madzi, malo opangira magetsi, mafakitale a boilers, makampani opanga zombo ndi zina zotero.

Kodi avalve pachipata?

Valve yachipata ndi valavu yoyenda mozungulira.Chovala cha valve chimayenda mmwamba kapena pansi kuti chitsegule kapena kutseka valve.Ma valve a zipata amathanso kugawidwa kukhala ma valve a zipata za mpeni malinga ndi kapangidwe kawo.Valve yachipata ndi valavu yanjira ziwiri yopanda mayendedwe oyenda.

Valve yachipata imatha kutsegulidwa kwathunthu kapena kutsekedwa kwathunthu, kotero valve yachipata ingagwiritsidwe ntchito poyenda ndi kudula, ndipo sangathe kusintha kayendedwe kake.Valve yachipata sikophweka kutsekedwa, choncho ndi yoyenera kwambiri ku zomera za simenti, mapepala ndi zamkati ndi zina zotero.

Vavu yachipata imatha kupangidwa ndi pulasitiki, chitsulo chosapanga dzimbiri, chitsulo chosapanga dzimbiri kapena chitsulo cha carbon.

Valavu yachipata imakhala ndi kukula kwake kwakukulu, kotero ingagwiritsidwe ntchito m'mafakitale aliwonse, monga mafakitale opangira chakudya, mankhwala amadzi onyansa, mafuta ndi gasi, ndi mafakitale opangira makina.

Ma valve onse a mpira ndi ma valve a zipata ali ndi ubwino wawo, kotero kumvetsetsa ntchito zawo kungakuthandizeni kusankha valve.Ngati mukufuna chitsogozo chosankha, ndinu olandiridwa kuti mutilankhule.Ndife okondwa kukuthandizani.
