產品詳細說明
SMC小型集裝式減壓閥響應時間可以短至幾個毫秒,即使是先導式電磁閥也可以控制在幾十毫秒內。由于自成回路,比之其它自控閥反應更靈敏。設計得當的電磁閥線圈功率消耗很低,屬節能產品;還可做到只需觸發動作,自動保持閥位,平時一點也不耗電。電磁閥外形尺寸小,既節省空間,又輕巧美觀。內外泄漏是危及安全的要素。其它自控閥通常將閥桿伸出,由電動、氣動、液動執行機構控制閥芯的轉動或移動。這都要解決長期動作閥桿動密封的外泄漏難題;唯有電磁閥是用電磁力作用于密封在隔磁套管內的鐵芯完成,不存在動密封,所以外漏易堵絕。電動閥力矩控制不易,容易產生內漏,甚至拉斷閥桿頭部;電磁閥的結構型式容易控制內泄漏,直至降為零。所以,電磁閥使用特別安全,尤其適用于腐蝕性、有毒或高低溫的介質。
供應SMC小型集裝式減壓閥的內部結構可分滑閥位置反饋、載荷壓力反饋和載荷流量反饋;閥的級數可分單級、雙級和多級。在電液伺服閥中,將電信號轉變為旋轉或直線運動的部件稱為力矩馬達或力馬達。力矩馬達浸泡在油液中的稱為濕式,不浸泡在油液中的稱為乾式。其中以滑閥位置反饋、兩級乾式電液伺服閥應用zui廣。電液伺服閥的工作原理是力矩馬達在線圈中通入電流后產生扭矩,使彈簧管上的擋板在兩噴嘴間移動,移動的距離和方向隨電流的大小和方向而變化。例如擋板向右移近噴嘴時,就在主閥芯兩端面上產生壓力差推動主閥芯左移,使壓力油口P 
S與載荷1口相通,回油口與載荷 2口相通。主閥芯左移的同時通過反饋桿對力矩馬達產生的力矩和擋板的位移進行負反饋。

產品特點
SMC小型集裝式減壓閥產品使用中注意事項及其型號: 
刀型閘閥的啟閉件是閘板,閘板的運動方向與流體方向相垂直,手動刀型閘閥只能作全開和全關,不能作調節和節流。閘板有兩個密封面,zui常用的模式閘板閥的兩個密封面形成楔形、楔形角隨閥門參數而異,通常為50,楔式刀型閘閥的閘板可以做成一個整體,叫做剛性閘板;也可以做成能產生微量變形的閘板,以改善其工藝性,彌補密封面角度在加工過程中產生的偏差,這種閘板叫做彈性閘板 
刀型閘閥關閉時,密封面可以只依靠介質壓力來密封,即依靠介質壓力將閘板的密封面壓向另一側的閥座來保證密封面的密封,這就是自密封.大部分刀型閘閥是采用強制密封的,即閥門關閉時,要依靠外力強行將閘板壓向閥座,以保證密封面的密封性本類閥門在管道中一般應當水平安裝。
供應SMC小型集裝式減壓閥就屬于這種類型的閥門,它包括旋啟式止回閥和升降式止回閥。旋啟式止回閥有一介鉸鏈機構,還有一個像門一樣的閥瓣自由地靠在傾斜的閥座表面上。為了確保閥瓣每次都能到達閥座面的合適位置,閥瓣設計在鉸鏈機構,以便閥瓣具有足夠有旋啟空間,并使閥瓣真正的、全面的與閥座接觸。閥瓣可以全部用金屬制成,也可以在金屬上鑲嵌皮革、橡膠、或者采用合成覆蓋面,這取決于使用性能的要求。旋啟式止回閥在*打開的狀況下,流體壓力幾乎不受阻礙,因此通過閥門的壓力降相對較小。升降式止回閥的閥瓣座落位于閥體上閥座密封面上。此閥門除了閥瓣可以自由地升降之外,其余部分如同截止閥一樣,流體壓力使閥瓣從閥座密封面上抬起,介質回流導致閥瓣回落到閥座上,并切斷流動。
