WGR2-0-WG230換向閥哈威hawe電磁閥
德國(guó)HAWE哈威的截止式換向閥的閥芯的行程和不帶截止的閥相比要短,流量大,換向比較快,易于設(shè)計(jì)成結(jié)構(gòu)緊湊的大直徑換向閥;滑動(dòng)密封面小,泄漏損失小,抗污染能力強(qiáng),氣源過濾精度低;由于閥芯始終承受壓縮空氣的壓力,因此換向閥的密封性能良好,但在高壓大流量的情況下,所需的換向力大,沖擊力也大,不適合靈敏度、高點(diǎn)。
哈威截止閥又稱截門閥,屬于強(qiáng)制密封式閥門,所以在閥門關(guān)閉時(shí),必須向閥瓣施加壓力,以強(qiáng)制密封面不泄漏。當(dāng)介質(zhì)由閥瓣下方進(jìn)入閥門時(shí),操作力所需要克服的阻力,是閥桿和填料的摩擦力與由介質(zhì)的壓力所產(chǎn)生的推力,關(guān)閥門的力比開閥門的力大,所以閥桿的直徑要大,否則會(huì)發(fā)生閥桿頂彎的故障
