Chiyambi ndi makhalidwe a valve chipata chamoto

Kutsegula ndi kutseka gawo lavalavu ya chipata cha motondi nkhosa yamphongo, ndi kayendedwe ka malangizo a nkhosa ndi perpendicular kwa madzimadzi malangizo.Valve yachipata imatha kutsegulidwa kwathunthu ndikutsekedwa kwathunthu, ndipo sichingasinthidwe ndikugwedezeka.Nkhosa yamphongo ili ndi malo awiri osindikizira.Njira yomwe imagwiritsidwa ntchito kwambiri ndi yakuti malo awiri osindikizira a valve yamphongo amapanga mphero.Ngodya ya wedge imasiyanasiyana ndi magawo a valve, nthawi zambiri 50. Pamene kutentha kwapakati sikuli kwakukulu, ndi 2 ° 52 '.Chipata cha valavu ya chipata cha wedge chikhoza kupangidwa chonse, chomwe chimatchedwa chipata cholimba;Itha kupangidwanso kukhala nkhosa yamphongo yomwe imatha kutulutsa kapindika pang'ono kuti ipititse patsogolo kusinthika kwake ndikupangitsa kupatuka kwa ngodya yosindikiza pamwamba pakukonza.Nkhosa yamphongo imeneyi imatchedwa zotanuka ram.

Mitundu ya mavavu a zipata zamoto imatha kugawidwa mu mavavu a pachipata cha wedge ndi ma valve ofananira pachipata molingana ndi kasinthidwe kapamwamba kosindikiza.Mavavu a chipata cha mphero amathanso kugawidwa kukhala mtundu umodzi wa chipata, mtundu wa mbale wapakhomo ndi mtundu wa chipata chotanuka;Parallel chipata valavu akhoza kugawidwa mu mbale chipata chimodzi ndi mbale awiri pachipata.Malingana ndi malo a ulusi wa tsinde la valve, akhoza kugawidwa m'mitundu iwiri:valavu yokwera pachipatandiVavu yachipata chosakwera.

Zofunikira za valve yamoto pachipata:
1. Kulemera kopepuka: thupi limapangidwa ndi chitsulo chakuda chakuda chakuda, ndipo kulemera kwake kuli pafupifupi 20% ~ 30% kuchepera kuposa vavu yachipata yachikhalidwe, yomwe ndi yabwino kuyika ndi kukonza.
Mpando wapansi pachipata: chitseko chikatsukidwa ndi madzi, zinthu zakunja monga miyala, matabwa, simenti, zitsulo zachitsulo ndi ma sundries zimayikidwa mu groove pansi pa valve, zomwe zimakhala zosavuta kuyambitsa madzi chifukwa cha kulephera kutseka mwamphamvu.Pansi pa valavu ya chipata chosindikizira mpando amatengera kapangidwe kameneka kakang'ono kofanana ndi ka makina a chitoliro chamadzi, zomwe sizili zophweka kuchititsa kuti ma sundries asungidwe ndikupangitsa kuti madzi aziyenda mosatsekeka.
2. Chophimba cha rabara chophatikizika: nkhosa yamphongo imatenga mphira wapamwamba kwambiri wamkati ndi kunja kwa mphira.Ukadaulo waukadaulo waku Europe woyambira mphira umathandizira kuti nkhosayo iwonetsetse miyeso yolondola ya geometric, ndipo RAM ya rabara ndi ductile iron casting imalumikizidwa mwamphamvu, sizovuta kugwa komanso kukumbukira bwino.
3. Thupi la valve loponyera mwatsatanetsatane: thupi la valve limapangidwa ndi kuponyedwa kolondola, ndipo mawonekedwe olondola a geometric amachititsa kuti atsimikizire kusindikiza kwa valve popanda kumaliza mkati mwa thupi la valve.
