通用真空阀门的用途浅析
下面简单介绍三精阀门的通用真空阀门的用途。
Following is a brief introduction to the use of universal vacuum valves for three-precision valves.
蝶阀为直通形式，手、气、电三种驱动方式由用户决定。手动蝶阀开启角度任意可调；智能型的气动和电动蝶阀其开启角度也任意可调。
The butterfly valve is a straight-through type. The three driving modes of hand, gas and electricity are decided by users. The opening angle of manual butterfly valve can be adjusted arbitrarily; the opening angle of intelligent pneumatic and electric butterfly valve can also be adjusted arbitrarily.
插板阀用在真空度要求高或管道尺寸要求高的场合。全通导、阀门漏率为10-7Pa.L/S，双向密封。驱动方式手、气、电动由用户决定。气动和电动均带信号反馈装置。
Plug-in valves are used in high vacuum or pipe size requirements. Full conductivity, valve leakage rate is 10-7Pa.L/S, two-way sealing. The driving mode of hand, pneumatic and electric is decided by the user. Both pneumatic and electric systems have signal feedback devices.
隔膜阀与球阀为直通式，并能用在正压和真空并存的场合。驱动方式手、气、电动由用户决定。
Diaphragm valves and ball valves are straight-through, and can be used in both positive pressure and vacuum situations. The driving mode of hand, pneumatic and electric is decided by the user.
挡板阀用在真空管道中角通和三通的地方。驱动方式为手、气、电磁、电动由用户决定。其中GDC—J型电磁高真空挡板阀为金属波纹管密封，其应用范围较广,也可当充气阀用；安装位置可任意,可反顶一个大气压,并有反馈信号输出。
The baffle valve is used in the corner and tee of the vacuum pipeline. The driving modes are hand, air, electromagnetic and electric, which are decided by users. Among them, GDC-J electromagnetic high vacuum baffle valve is a metal bellows seal, which has a wide range of applications and can also be used as an inflatable valve; the installation position can be arbitrary, it can reverse top an atmospheric pressure, and has feedback signal output.
电磁真空带充气阀与电磁真空压差阀是专门用于防止机械真空泵返油的真空阀，安装于机械真空泵的进气口，并与泵同步开启和关闭。一般不能用到其它地方，也就是说不能用于真空系统中作放气之用。选用电磁真空压差阀的优点是耗电量很小，节省能源；DN≤50的阀体材质为铝合金，重量轻，体积小，阀板关闭速度快。
Electromagnetic vacuum belt inflatable valve and electromagnetic vacuum differential pressure valve are vacuum valves specially designed to prevent oil return of mechanical vacuum pump. They are installed in the intake port of mechanical vacuum pump and open and close synchronously with the pump. Generally, it can't be used in other places, that is to say, it can't be used for venting in vacuum system. The advantages of using electromagnetic vacuum differential pressure valve are low power consumption and energy saving. The valve body with DN < 50 is made of aluminium alloy, light weight, small volume and fast closing speed of valve plate.
