Nzira yekugadzira yePVC bhora mavharuvhuinosanganisira hunyanzvi hwekugadzira uye yakakwirira mwero wekutonga zvinhu, nematanho anotevera akakosha:
1. Kusarudzwa kwezvinhu uye kugadzirira
(a) Kushandisa mapurasitiki einjiniya akadai sePP (polypropylene) uye PVDF (polyvinylidene fluoride) sechinhu chikuru chekuona kudhura kwakanyanya uye kusagadzikana kwekuora; Paunenge uchisanganisa, zvakakosha kunyatsosanganisa masterbatch uye toughening agent, uye mushure mokunge simba richisangana nechiyero, musanganiswa unofanirwa kupisa kusvika ku80 ℃ uye kumutswa zvakaenzana.
(b) Batch yega yega yezvakagadzirwa zvinofanirwa kutorwa sampuli yekumanikidza kuramba paramita uye melt index, ine chikanganiso chinodzorwa mukati me0.5% kudzivirira deformation uye kuvuza.
2. Valve musimboti kugadzirwa (yakabatanidzwa dhizaini)
(a) Ivhavha yepakati inotora chimiro chakabatanidzwa, uye tsinde yevharuvhu yakanyatsobatanidzwa kune bhora revhavha. Nyaya yacho inogona kusarudzwa kubva kusimbi (yakadai sekuwedzera simba), mapurasitiki (seakareruka), kana zvinhu zvakaumbwa (zvakadai sepurasitiki yakaputirwa simbi).
(b) Paunenge uchigadzira chivharo chevhavha, shandisa chigadziro chekucheka nhanho nhatu kuti ucheke chikamu chechidimbu, kuderedza chiyero chekucheka ne 0.03 millimeters per sitiroko kuti uderedze chiyero chekuputsika; Wedzera graphite sealing layer stamping kumagumo kuti uwedzere kusaita ngura
3. Valve body injection molding
(a) Isa iyo yakasanganiswa yevharuvhu musimboti (inosanganisira bhora revhavha uye tsinde yevharuvhu) muforoma yakasarudzika, kupisa uye kunyungudutsa zvinhu zvepurasitiki (kazhinji polyethylene, polyvinyl chloride kana ABS), uye jekiseni muforoma.
(b) Mold design inoda kugadziriswa: nzira inoyerera inotora katatu yakagoverwa yakanyunguduka, uye makona emakona ari ≥ 1.2 millimeters kudzivirira kuputika; Iwo majekiseni maparamendi anosanganisira screw speed ye55RPM kudzikisa mabhuru emhepo, nguva yekubata inopfuura 35 seconds kuti ive nechokwadi chekubatana, uye nhanho yekudzora tembiricha yebhara (200 ℃ yekudzivirira kubikira padanho rekutanga uye 145 ℃ yekuumbwa kuchinjika mune inotevera nhanho).
(c) Paunenge uchidhiza, gadzirisa tembiricha yeyakagadziriswa mold cavity kusvika 55 ℃, ine mutsetse mukuru kupfuura 5 ° kudzivirira kukwenya, uye kudzora marara pasi pe8%.
4. Gungano uye kugadziriswa kwezvishandiso
(a) Mushure mekunge muviri wevharuvhu watonhora pasi, isa chivharo chevhavha, zvisimbiso, uye fasteners; Gadzira induction locator online, iyo inozongo simudza alarm kana kutsauka kwakapfuura 0.08 millimeters, kuve nechokwadi kurongeka kwezvishandiso senge chiteshi kupatsanura.
(b) Mushure mekucheka, zvinodikanwa kuti uone gaka riri pakati pemuviri wevharuvhu nepakati pevhavha, uye kana zvichidikanwa, wedzera mabhokisi ekuzadza kuti uwedzere chisimbiso chimiro.
5.Kuedza uye Kuongorora
(a) Ita kuyedza kwemhepo-yemvura kutenderera: jekiseni 0.8MPa yekumanikidza mvura kwemaminetsi gumi uye tarisa iyo deformation huwandu (≤ 1mm inokodzera); Iyo yekutenderera torque bvunzo yakaiswa ne 0.6N · m overload kuchengetedza.
(b) Kuisa chisimbiso kunosanganisira kuyedzwa kwemhepo (kutarisa nemvura ine sipo pa 0.4-0.6MPa) uye kuyedza simba regoko (kubata ka1.5 nguva yekumanikidza kushanda kweminiti imwe), ine yakazara yekuongorora chiyero inofukidza zvinopfuura makumi manomwe epasirese zvinodiwa.
