Mfundo za kusankha ma valve ndi masitepe osankha ma valve

Mfundo yosankha ma valve
(1) Chitetezo ndi kudalirika. Petrochemical, siteshoni magetsi, zitsulo ndi mafakitale ena zofunika kupanga ntchito mosalekeza, khola, yaitali mkombero ntchito. Choncho, valavu yofunikira iyenera kukhala yodalirika kwambiri, chitetezo chachikulu, sichikhoza kuyambitsa chitetezo chachikulu cha kupanga ndi kuvulala kwaumwini chifukwa cha kulephera kwa valve, kukwaniritsa zofunikira za nthawi yayitali ya chipangizocho. Komanso, kuchepetsa kapena kupewa kutayikira chifukwa mavavu, pangani woyera, wotukuka fakitale, kukhazikitsa thanzi, chitetezo, kasamalidwe chilengedwe.

(2) Kukwaniritsa zofunika kupanga ndondomeko. Valavu iyenera kukwaniritsa zofunikira zogwiritsira ntchito sing'anga, kuthamanga kwa ntchito, kutentha kwa ntchito ndi ntchito, zomwe ndizofunikira kwambiri pakusankha ma valve. Ngati valavu ikufunika kuti iteteze kupanikizika kwambiri ndi kutulutsa sing'anga yambiri, valve yotetezera ndi valve yowonjezera idzasankhidwa; kuteteza valavu yapakati yobwerera panthawi ya ntchito, tengeranichekeni valavu; Kuchotsa madzi a condensate, mpweya ndi mpweya wina wosasunthika wopangidwa mu chitoliro cha nthunzi ndi zida, ndikuletsa kuthawa kwa nthunzi, valavu iyenera kugwiritsidwa ntchito. Kuonjezera apo, pamene sing'angayo ikuwononga, zipangizo zabwino zokana zowonongeka ziyenera kusankhidwa.

(3) Kuchita bwino, kukhazikitsa ndi kukonza. Vavu ikayikidwa, wogwiritsa ntchitoyo ayenera kudziwa bwino momwe ma valve akulowera, chizindikiro chotsegulira ndi chizindikiro chowonetsera, kuti athe kuthana ndi zolakwika zosiyanasiyana. Pa nthawi yomweyi, mawonekedwe amtundu wa valve osankhidwa ayenera kukhala momwe angathere, kukhazikitsa ndi kukonza bwino.

(4) Chuma. Pansi pa kukumana ndi ntchito yanthawi zonse ya mapaipi opangira ma valve, ma valve okhala ndi mtengo wotsika wopanga komanso mawonekedwe osavuta ayenera kusankhidwa momwe angathere kuti achepetse mtengo wa chipangizocho, kupewa kuwononga zida zopangira ma valve ndikuchepetsa mtengo wa kukhazikitsa ndi kukonza ma valve. pambuyo pake.

Masitepe osankha ma valve
1.Tsimikizirani momwe ntchito ya valve ikuyendera malinga ndi kugwiritsa ntchito valavu mu chipangizo kapena ndondomeko ya payipi. Mwachitsanzo, sing'anga yogwira ntchito, kuthamanga kwa ntchito ndi kutentha kwa ntchito, etc.

2.Tsimikizirani mlingo wa ntchito yosindikiza ya valve malinga ndi malo ogwirira ntchito, malo ogwirira ntchito ndi zofunikira za ogwiritsa ntchito.

3.Tsimikizirani mtundu wa valve ndi kuyendetsa galimoto molingana ndi cholinga cha valve. Mitundu mongavalavu ya butterfly yokhazikika, valavu, valavu yachipata,valve balancing, etc. Kuyendetsa mode monga nyongolotsi gudumu nyongolotsi, magetsi, pneumatic, etc.

4.Malinga ndi chizindikiro cha dzina la valve. Kuthamanga mwadzina ndi kukula kwadzina kwa valve kudzagwirizana ndi chitoliro chokhazikitsidwa. Ma valve ena amatsimikizira kukula kwadzina kwa valve malinga ndi kuchuluka kwa kuthamanga kapena kutulutsa kwa valve panthawi yovomerezeka yapakati.

5.Tsimikizirani mawonekedwe a kugwirizana kwa valve kumapeto kwa valve ndi chitoliro molingana ndi zochitika zenizeni zogwirira ntchito ndi kukula kwa dzina la valve. Monga flange, kuwotcherera, kopanira kapena ulusi, etc.

6.Tsimikizirani mawonekedwe ndi mawonekedwe a mtundu wa valve malinga ndi malo oyika, malo osungiramo, ndi kukula kwadzina kwa valve. Monga valavu yachipata chamdima, valavu yapadziko lapansi, valavu ya mpira, ndi zina zotero.

Malinga ndi mawonekedwe a sing'anga, kuthamanga kwa ntchito ndi kutentha kwa ntchito, kusankha kolondola komanso koyenera kwa chipolopolo cha valve ndi zipangizo zamkati.
