進口自保持式電磁閥
進口自保持式電磁閥產品概述
美國WORK,從根本上解決了由于電磁閥線圈*通電而燒毀的尷尬局面,其特點為節能、省電、線圈不發熱。
工作原理
電磁閥初始狀態為關閉,介質無法流通。點擊開啟開關,即頂部線圈開關,頂部線圈通電,閥桿帶動活塞上升,閥門開啟,介質得以流通。點擊關閉開關,即側面線圈開關,側面線圈通電,閥桿帶動活塞下移,閥門關閉,介質得以截止。
種類
進口單線圈式自保持電磁閥
1、技術參數:
進口單線圈式自保持電磁閥
(1)適用介質:蒸汽、空氣、油、水、燃氣等流體
(2)口徑大小:DN1-DN50
(3)接口尺寸:G1/8〃-G2〃(可做美標NPT接口)、25F-50F
(4)適用壓力:0-1.6MPa
(5)適用溫度:-20-+350℃
(6)電源電壓:DC6V-DC24V(單線圈式自保持電磁閥只能采用直流電源)
(7)響應時間:50-120毫秒
(8)閥體材質:304不銹鋼、黃銅
(9)通電時間:脈沖電源1-3秒
2、工作原理
當電磁閥線圈正負極通直流電源的時候,電磁閥打開,當斷電后,電磁閥仍然處于開啟狀態;當電磁閥線圈正負極通反向的直流電源的時候,電磁閥關閉,斷電后,電磁閥仍然處于關閉狀態.
雙線圈式自保持電磁閥1、技術參數: 雙線圈式自保持電磁閥
(1)適用介質:蒸汽、空氣、油、水、燃氣等流體
(2)口徑大小:DN1-DN1000
(3)接口尺寸:G1/8〃-G2〃、15F-1000F(可做美標螺紋和法蘭)
(4)適用壓力:0-0.6MPa、0-1.6MPa、0.03-2.5MPa、0.1-4MPa、0.1-6.3MPa、0.1-10MPa、0.1-20MPa、0.1-30MPa
(5)適用溫度:-196-+450℃
(6)電源電壓:AC220V、AC110V、AC127V、AC24V、DC24V、DC12V(雙線圈式自保持電磁閥可以選擇任意電源)
(7)響應時間:小口徑50-120毫秒、大口徑小于1秒
(8)閥體材質:304不銹鋼、球墨鑄鐵
(9)通電時間:脈沖電源1-3秒
2、工作原理
當線圈A通電時,電磁閥打開,介質流通,斷電后,電磁閥仍然處于打開狀態;當線圈B通電的時候,電磁閥關閉,介質截斷,斷電后,電磁閥仍然處于關閉狀態.
自保持電磁閥優點1、由于自保持電磁閥不用*通電,實現了節能、環保.
2、從根本上解決了由于電磁閥線圈*通電而燒毀的尷尬局面.
3、幾乎在整個控制過程中不用電源,杜絕了由于電源帶來的安全隱患.
