Njira zopangira ma valve:
1. Tanthauzirani kugwiritsidwa ntchito kwa valve mu zipangizo kapena chipangizo, dziwani momwe ma valve amagwirira ntchito: sing'anga yoyenera, kuthamanga kwa ntchito, kutentha kwa ntchito ndi zina zotero.
2. Dziwani kuchuluka kwadzina ndi njira yolumikizira chitoliro cholumikizira ndi valavu: flange, ulusi, kuwotcherera, jekete, kukonza mwachangu, ndi zina zambiri.
3. Dziwani njira yogwiritsira ntchito valve: manual, magetsi, electromagnetic, pneumatic kapena hydraulic, magetsi kapena hydraulic linkage, etc.
4. Malingana ndi sing'anga yomwe imaperekedwa ndi payipi, kuthamanga kwa ntchito ndi kutentha kwa ntchito, zipangizo za chipolopolo cha valve ndi ziwalo zamkati zimasankhidwa: chitsulo chosungunuka, chitsulo chosasunthika, chitsulo cha nodular, chitsulo cha carbon, alloy zitsulo, zitsulo zosapanga dzimbiri zosapanga asidi. , copper alloy, etc.
5. Sankhani mitundu ya ma valve: ma valve otsekedwa, ma valve oyendetsa, ma valve otetezera, ndi zina zotero.
6. Dziwani mitundu ya ma valve: ma valve a zipata, ma valve a globe, ma valve a mpira, ma valve a butterfly, ma valve othamanga, ma valve otetezera, ma valve otetezera kuthamanga, misampha ya nthunzi, etc.
7. Dziwani magawo a mavavu: Kwa ma valve odziwikiratu, kukana kovomerezeka, kutulutsa mphamvu, kuthamanga kwa msana, ndi zina zotero zimatsimikiziridwa poyamba malinga ndi zosowa zosiyanasiyana, ndiyeno m'mimba mwake mwadzina la payipi ndi m'mimba mwake wa dzenje la mpando wa valve zimatsimikiziridwa.
8. Dziwani magawo a geometric a valve yosankhidwa: kutalika kwa mapangidwe, mawonekedwe a kugwirizana kwa flange ndi kukula kwake, kutalika kwa kayendetsedwe ka valve mutatha kutsegula ndi kutseka, kukula kwa dzenje la bolt ndi chiwerengero cha kugwirizana, kukula kwa mawonekedwe a valve, ndi zina zotero.
9 .Gwiritsani ntchito zomwe zilipo: Katundu wazinthu zamavavu, zitsanzo zama valve, ndi zina zambiri kuti musankhe zinthu zoyenera.
Maziko osankha ma valve:
1. Kugwiritsa ntchito, machitidwe ogwiritsira ntchito ndi njira yoyendetsera valve yosankhidwa.
2. Katundu wa sing'anga ntchito: kuthamanga ntchito, kutentha ntchito, dzimbiri ntchito, kaya particles olimba ali, kaya sing'anga ndi poizoni, kaya ndi kuyaka, kuphulika sing'anga, sing'anga mamasukidwe akayendedwe ndi zina zotero.
3. Zofunikira pamayendedwe amadzimadzi a valve: kukana kuthamanga, kutulutsa mphamvu, mawonekedwe othamanga, kalasi yosindikiza, ndi zina.
4. Kuyika muyeso ndi zofunikira za kukula kwake: m'mimba mwake mwadzina, njira yolumikizira ndi mapaipi ndi kukula kwa kugwirizana, kukula kwa ndondomeko kapena kuchepetsa kulemera, ndi zina zotero.
5. Zofunikira zowonjezera zodalirika za mankhwala a valve, moyo wautumiki ndi kuphulika kwa zipangizo zamagetsi. (Chisamaliro chiyenera kulipidwa posankha magawo: ngati valavu iyenera kugwiritsidwa ntchito pofuna kulamulira, zowonjezera zowonjezera ziyenera kutsimikiziridwa motere: njira yogwiritsira ntchito, zofunikira zazikulu ndi zochepa zoyenda, kutsika kwa kuthamanga kwabwino, kutsika kwapakati pa kutsekedwa, kupitirira ndi Kuthamanga kochepa kwa valve.)
Malingana ndi maziko omwe tawatchula pamwambawa ndi masitepe osankha ma valve, posankha ma valve moyenera komanso molondola, m'pofunika kumvetsetsa bwino za mkati mwa mitundu yosiyanasiyana ya ma valve kuti apange chisankho choyenera kwa ma valve omwe amakonda. Kuwongolera komaliza kwa payipi ndi valve. Chotsegulira valavu chimayang'anira kayendedwe kapakati papaipi. Maonekedwe a valve othamanga amachititsa kuti valavu ikhale ndi makhalidwe ena othamanga. Izi ziyenera kuganiziridwa posankha valavu yoyenera kwambiri kuti muyike mu dongosolo la mapaipi.
