Izimbangela Ezivamile Neziphakamiso Zokwelapha Zokuphambuka Kwesakhiwo Se-Bonnet
Isakhiwo sebhonethi asiyona inkinga enkulu kumavalvu amancane, kodwa uma sesingaphezu kwe-DN400, iphutha lokuhlanganisa liba lula ukuliveza. Amavalvu amaningi ebhola noma amavalvu esango endaweni yephrojekthi anokwehluleka okungavamile kokuvula nokuvala noma ukupakisha, futhi konke kuhlobene nokungafani noma ukuphambuka kwesembozo sevalvu.
Ngaphambilini sithathe iphrojekthi ye-ball valve enkulu yobubanzi bezindawo zokumba, futhi ikhasimende lathi umsindo wokuvula nokuvala awulungile, futhi i-ball valve esetshenziswa ngesandla inamathele phakathi. Ekuqaleni, babecabanga ukuthi kuyinkinga ngesiqu se-valve noma ibhola, kodwa kamuva sabuyela efektri ukuyohlola ukuthi bekuwukushaya okuncane kobuso be-flange ohlangothini lwesembozo se-valve, okwabangela ukuthi imbobo yesihlalo somshafti ongezansi isuke enkabeni yomzimba we-valve ngo-0.3mm. Ayibukeki inkulu, kodwa ngokushesha nje lapho umongo we-ball uphenduka, i-axis ayihambisani futhi i-torque ayizinzile.
Ukuphendula lolu hlobo lwenkinga, manje sinikeza amakhasimende isiphakamiso: umdwebo kumele uphawulwe ngokucacile ngomphezulu wokubeka, futhi ngokuvamile kunconywa ukusebenzisa umphezulu we-flange ongaphezulu noma umgodi ophakathi njengereferensi yokwenza i-clamping. Ikakhulukazi kuma-diameter amakhulu, sincoma i-integral vertical turning machining, engahlukaniswanga imisebenzi emibili. Uma uhlangothi lwekhasimende lungenakuboshwa lulonke, singasiza ekwengezeni imigqa yokubeka noma amakholomu okuqondisa ngokuya ngomdwebo wenqubo.
Ngaphezu kwalokho, ngesikhathi sokuhlanganiswa kweminye imisebenzi endaweni, ukuhlukaniswa kwembobo yebholithi yesembozo sevalvu kuholela ekuhlanganisweni okuphoqelelwe, okubonakala kungenankinga ukuyifaka, kodwa empeleni, ukucindezeleka kokulayisha kusengaphambili bekungalingani, futhi kulula ukukukhulula noma ukuvuza ngemva kwesikhathi sokusebenza. Ngokuvamile senza isiqinisekiso sokuhlanganiswa kwe-mock ngaphambi kokuthunyelwa, futhi ubukhulu obuyinhloko bonke buyizikali zokuqinisekisa ukuthi ukugijima kwendandatho ye-flange kungaphakathi kuka-0.05, nokuthi ukuma kwembobo yokuthwala kanye ne-axis kusezingeni elijwayelekile.
Nakuba i-bonnet iyisiqeshana esifanelana kahle, 'iyisiqalo' sokunemba kwesakhiwo esingaphezulu sonke, futhi uma singalungile, umongo webhola, isiqu se-valve, kanye nebhokisi lokugcwalisa konke kuzothinteka. Kunconywa ukuthi ikhasimende licabangele ubudlelwano bokulingana esiteji sokuklama, futhi uma kudingeka, singanikeza neseluleko sesakhiwo somhlangano noma sisize ekulungiseni i-logic yokulinganisa ukuze sigweme ukusebenza kabusha.
