Inqubo yokukhiqiza yeAma-valve ebhola e-PVCkuhilela ubuciko obunembayo nokulawulwa kwezinto ezibonakalayo okusezingeni eliphezulu, ngezinyathelo ezibalulekile ezilandelayo:
1. Ukukhetha nokulungiselela impahla
(a) Ukusebenzisa amapulasitiki obunjiniyela afana ne-PP (i-polypropylene) ne-PVDF (i-polyvinylidene fluoride) njengezinto eziyinhloko zokuqinisekisa ukusebenza kahle kwezindleko kanye nokumelana nokugqwala; Lapho uxuba, kubalulekile ukuxuba ngokunembile i-masterbatch ne-ejenti eqinisayo, futhi ngemva kokuba amandla ehlangabezana nesilinganiso, ingxube kufanele ishise ibe ngu-80 ℃ futhi inyakaze ngokulinganayo.
(b) Iqoqo ngalinye lezinto zokusetshenziswa kufanele lithathwe isampula ukuze kutholwe imingcele yokumelana nokucindezela kanye nenkomba encibilikayo, kube nephutha elilawulwa ngaphakathi kuka-0.5% ukuvimbela ukuguga nokuvuza.
2. Ukukhiqizwa kwe-valve core (umklamo ohlanganisiwe)
(a) I-valve core yamukela isakhiwo esihlanganisiwe, futhi isiqu se-valve sixhunywe ngokuqinile ebholeni le-valve. Izinto ezisetshenziswayo zingakhethwa ensimbi (njengokukhula kwamandla), ipulasitiki (efana nesisindo esincane), noma impahla eyinhlanganisela (njengensimbi egoqwe ngepulasitiki).
(b) Lapho wenza umgogodla we-valve, sebenzisa ithuluzi lokusika elizinyathelo ezintathu ukuze usike ingxenye yobubanzi, unciphise inani lokusika ngamamilimitha angu-0.03 i-stroke ngayinye ukuze unciphise izinga lokuphuka; Engeza isitembu sesendlalelo se-graphite ekugcineni ukuze uthuthukise ukumelana nokugqwala
3. Ukubumba umjovo womzimba we-valve
(a) Beka i-valve core edidiyelwe (okuhlanganisa ibhola le-valve nesiqu se-valve) esikhunjeni esenziwe ngokwezifiso, ukushisa futhi uncibilikise impahla yepulasitiki (ngokuvamile i-polyethylene, i-polyvinyl chloride noma i-ABS), bese uyijova esibunjeni.
(b) Idizayini yesikhunta idinga ukuthuthukiswa: isiteshi sokugeleza sithatha inyibiliki emithathu esabalalisiwe yomjikelezo, futhi amakhona amakhona angu-≥ 1.2 amamilimitha ukuvimbela ukuqhekeka; Imingcele yomjovo ihlanganisa isivinini esiyisikulufu esingu-55RPM sokunciphisa amabhamuza omoya, isikhathi sokubamba esingaphezu kwamasekhondi angu-35 ukuqinisekisa ukucinana, nokulawula okuhleliwe kwezinga lokushisa lomgqomo (200 ℃ wokuvimbela ukupheka esigabeni sokuqala kanye no-145 ℃ sokubumba ukuzivumelanisa nesigaba sakamuva).
(c) Uma ubhidliza, lungisa izinga lokushisa lesikhunta esingashintshi sibe ngu-55 ℃, ngomthambeka omkhulu kuno-5 ° ukugwema ukunwaya, futhi ulawule izinga lemfucuza libe ngaphansi kuka-8%.
4. Ukuhlanganisa nokucutshungulwa kwezesekeli
(a) Ngemva kokuba umzimba wamavalvu uphole, faka isembozo sevalvu, ama-seal, kanye nezinsimbi; Setha indawo yokubeka ku-inthanethi, ezocupha i-alamu ngokuzenzakalelayo uma ukuchezuka kudlula amamilimitha angu-0.08, kuqinisekiswe ukuqondana okunembayo kwezinsiza ezifana nabahlukanisi beziteshi.
(b) Ngemuva kokusika, kuyadingeka ukuqinisekisa igebe phakathi komzimba we-valve kanye ne-valve core, futhi uma kunesidingo, engeza ukufakwa kwamabhokisi okugcwalisa ukuze kwandiswe isakhiwo sokuvala
5.Ukuhlola Nokuhlola
(a) Yenza ukuhlolwa kokujikeleza kwamanzi komoya: faka amanzi okucindezela okungu-0.8MPa imizuzu eyi-10 futhi uhlole inani lokuguqulwa (≤ 1mm lifanelekile); Ukuhlolwa kwe-torque ejikelezayo kusethwe ngokuvikelwa kokulayishwa ngokweqile okungu-0.6N · m.
(b) Ukuqinisekisa ukuvala kuhlanganisa ukuhlolwa komfutho womoya (ukubuka ngamanzi anensipho ku-0.4-0.6MPa) kanye nokuhlolwa kwamandla egobolondo (ukubamba izikhathi ezingu-1.5 ukucindezela kokusebenza iminithi elingu-1), ngezinga lokuhlola eligcwele elihlanganisa izidingo ezijwayelekile zikazwelonke ezingaphezu kuka-70.
