Kune marudzi mazhinji emavharuvhu, asi basa rekutanga rakafanana, ndiko kuti, kubatana kana kugura kuyerera kwepakati. Naizvozvo, dambudziko rekurarama rine chisimbiso vevharuvhu rakakurumbira.
Kuve nechokwadi chekuti vharuvharu yacho inogona kucheka iyo yepakati yekuyerera zvakanaka pasina kubhururuka, zvinodikanwa kuti uve nechokwadi chekuti chisimbiso cheVolve chakasimba. Pane zvikonzero zvakawanda zvekuvandudza mauto, kusanganisira zvisingafungi kugadzirwa kwechimiro, kusimbisa kusimbisa nzvimbo Zvakanaka, nokudaro kugadzira dambudziko rekusvetuka. Naizvozvo, vhoriyamu yekuisa tekinoroji yakakosha tekinoroji yakakosha ine chekuita neValve performance uye mhando, uye inoda yakarongeka uye yekutsvaga kwakadzika.
Iyo inowanzoshandiswa kusimbisa mari yemavhidhiyo inonyanya kusanganisira mhando dzinotevera:
1. NBR
Kupesana kwakanakisa kusagadzikana, kupfeka kupokana, kupokana kwakanaka, kudenha kwakasimba. Zvinokanganisika zvaro zvirombo zvakashata kudzikisira kupokana, murombo ozone kuramba, zvivakwa zvisina kunaka zvemagetsi, uye zvishoma zvakaderera elasticity.
2 E EPDM
Chinhu chinonyanya kukosha che EPDM ndiyo yakakwirira kwazvo oxidation kuramba, ozone kuramba uye kupokana kwekugadzirisa. Sezvo EPDM ndeyemhuri yePolydolefin, ine hunhu hwakanaka hwekuita hukuru.
3. PTFE
PTFE ine yakasimba yemakemikari kuramba, kuramba kune akawanda mafuta uye solvent (kunze kweKenji uye kupokana nemamiriro ekunze uye kupokana neOzone, asi kuramba zvakaipa.
4. Kanda iron
Ongorora: kukanda simbi inoshandiswa kumvura, gasi uye oiri midhiya ne tembiricha ye≤100°C uye kudzvanywa kwe≤1.6mpa.
5. Nickel-based alloy
Ongorora: Nickel-based alloys anoshandiswa pombi ine tembiricha ye -70 ~ 150°C uye injini yekumanikidza PN≤20.5mpa.
6. Alloy Alloy
Copper Alloy ine yakanaka kupfeka kurwisa uye yakakodzera kune mvura uye pombi yemapipi ne tembiricha≤200℃uye zita rekudzvinyirira PN≤1.6mpa.
