Inkqubo yemveliso yeIivalvu zebhola zePVCibandakanya ubugcisa obuchanekileyo kunye nolawulo lwemathiriyeli ekumgangatho ophezulu, ngamanyathelo aphambili alandelayo:
1. Ukukhethwa kwezinto kunye nokulungiselela
(a) Ukusebenzisa iiplastiki zobunjineli ezifana ne-PP (i-polypropylene) kunye ne-PVDF (i-polyvinylidene fluoride) njengezona zinto zibalulekileyo zokuqinisekisa ukuphumelela kweendleko eziphezulu kunye nokuxhathisa ukubola; Xa udibanisa, kuyimfuneko ukudibanisa ngokuchanekileyo i-masterbatch kunye ne-agent enzima, kwaye emva kokuba amandla adibana nomgangatho, umxube kufuneka utshiswe kwi-80 ℃ kwaye udibanise ngokulinganayo.
(b) Ibhetshi nganye yemathiriyeli ekrwada kufuneka ithathwe iisampulu kwiiparamitha zokumelana noxinzelelo kunye nesalathiso sokunyibilika, kunye nempazamo elawulwa ngaphakathi kwe-0.5% ukuthintela ukuguquka kunye nokuvuza.
2. Ukuveliswa kweValve engundoqo (uyilo oludibeneyo)
(a) Undoqo wevalve wamkela isakhiwo esidityanisiweyo, kwaye isiqu sevalve sidityaniswe ngokuthe ngqo kwibhola yevalve. Izinto eziphathekayo zinokukhethwa kwisinyithi (njengokonyuka kwamandla), iplastiki (efana nekhaphukhaphu), okanye izinto ezidibeneyo (ezifana neplastiki eboshwe ngesinyithi).
(b) Xa ulungisa i-valve core, sebenzisa isixhobo sokusika samanyathelo amathathu ukusika inxalenye yobubanzi, ukunciphisa inani lokusika nge-0.03 millimeters nge-stroke ukuze kuncitshiswe izinga lokuphuka; Yongeza umaleko wokutywina wegraphite ekupheleni ukomeleza ukuxhathisa kokumhlwa
3. Ukubumba inaliti yomzimba wevalvu
(a) Beka undoqo wevalve edityanisiweyo (kuquka ibhola yevalve kunye nesiqu sevalve) kwisingundo esilungiselelweyo, ubushushu kunye nokunyibilikisa imathiriyeli yeplastiki (idla ngokuba yi-polyethylene, i-polyvinyl chloride okanye i-ABS), kwaye uyigalele kubumba.
(b) Uyilo lwe-Mold kufuneka luphuculwe: umjelo wokuhamba uthatha umjikelezo wesithathu osasazwayo, kunye neekona zekona ≥ 1.2 millimeters ukukhusela ukuqhekeka; Iiparamitha zenaliti ziquka isantya se-screw se-55RPM ukunciphisa amaqamza omoya, ixesha lokubamba ngaphezu kwemizuzwana ye-35 ukuqinisekisa ukuxinana, kunye nolawulo oluhleliweyo lobushushu bombhobho (200 ℃ yokuthintela ukupheka kwinqanaba lokuqala kunye ne-145 ℃ yokulungelelanisa ukubumba kwinqanaba lamva).
(c) Xa udiliza, lungisa ubushushu bomngxuma wokungunda osisigxina ukuya kuma-55 ℃, kunye nethambeka elingaphezulu kwe-5 ° ukuphepha ukukrwela, kwaye ulawule isantya senkunkuma esingaphantsi kwe-8%.
4. INdibano kunye nokusetyenzwa kwezixhobo
(a) Emva kokuba umzimba wevalve uphole, fakela isigqubuthelo sevalvu, izitywini kunye neziqhoboshi; Misela i-locator ye-induction kwi-intanethi, eya kubangela i-alam ngokuzenzekelayo ukuba ukutenxa kudlula i-0.08 millimeters, ukuqinisekisa ukulungelelaniswa okuchanekileyo kwezixhobo ezifana nezahluli zetshaneli.
(b) Emva kokusikwa, kuyimfuneko ukuqinisekisa umsantsa phakathi komzimba wevalve kunye nesiseko sevalve, kwaye ukuba kuyimfuneko, yongeza ukufakwa kwebhokisi yokuzalisa ukuze kulungiswe isakhiwo sokutywina.
5.Uvavanyo kunye noHlolo
(a) Yenza uvavanyo lokujikeleza kwamanzi emoyeni: faka i-0.8MPa yoxinzelelo lwamanzi kwimizuzu eyi-10 kwaye ukhangele inani lokuguqulwa (≤ 1mm ifanelekile); Uvavanyo lwe-torque yokujikeleza lusekwe nge-0.6N · m ukhuseleko lomthwalo ogqithisiweyo.
(b) Ukuqinisekiswa kokutywina kubandakanya uvavanyo loxinzelelo lomoya (uqwalaselo ngesepha yamanzi kwi-0.4-0.6MPa) kunye novavanyo lwamandla eqokobhe (ubambe i-1.5 kumaxesha oxinzelelo lokusebenza umzuzu o-1), kunye nomgangatho wokuhlola ogcweleyo obandakanya ngaphezulu kwe-70 yeemfuno zomgangatho wesizwe.
