寶德6223型伺服輔助式比例閥/BURKERT6223型比例閥
寶德6223型伺服輔助式比例閥瓣沿著閥體垂直線滑動的止回閥，內(nèi)螺紋止回閥只能安裝在水平管道上，在高壓小口徑止回閥上閥瓣可采用圓球。蝶式止回閥的閥體形狀與截止閥樣（可與截止閥通用），因此它的流體阻力系數(shù)較大。其結(jié)構(gòu)與截止閥相似，閥體和閥瓣與截止閥相同。閥瓣上部和閥蓋下部加工有導向套簡，閥瓣導向簡可在閥盞導向簡內(nèi)自由升降，當介質(zhì)順流時，閥瓣靠介質(zhì)推力開啟，當介質(zhì)停流時，閥瓣靠自垂降落在閥座上，起阻止介質(zhì)逆流作用。直通式蝶式止回閥介質(zhì)進出口通道方向與閥座通道方向垂直；立式升降式止回閥，其介質(zhì)進出口通道方向與閥座通道方向相同，其流動阻力較直通式小。寶德6223型伺服輔助式比例閥的運動曲線，2為排氣閥的運動曲線?？v坐標代表升程h，橫坐標為曲軸的轉(zhuǎn)角（或時間）。從圖中可以看出氣閥的開啟和關(guān)閉都是比較快的。并且氣閥的開啟速度總是要高于氣閥的關(guān)閉速度，這是因為氣閥的開啟過程是在活塞速度很高的階段進行的，而氣閥的關(guān)閉卻是在活塞已位移到接近止點位置，活塞速度已經(jīng)很低的情況下進行的。氣閥在啟閉過程中，閥片、升程限制器及閥座都將受到交變沖擊載荷作用，很容易造成磨損和破壞。寶德6223型伺服輔助式比例閥瓣繞轉(zhuǎn)軸作旋轉(zhuǎn)運動。其流體阻力般小于升降式止回閥，它適用于較大口徑的場合。旋啟式止回閥根據(jù)閥瓣的數(shù)目可分為單瓣旋啟式、雙瓣旋啟式及多瓣旋啟式三種。單瓣旋啟式止回閥般適用于中等口徑的場合。大口徑管路選用單瓣旋啟式止回閥時，為減少水錘壓力，采用能減小水錘壓力的緩閉止回閥。雙瓣旋啟式止回閥適用于大中口徑管路。
