气动阀工作原理:气动阀利用过程本身的压力或压差来驱动控制阀动作,也可用.温包式检测元件将温度转换为压力,然后驱动控制阀动作。其特点是结构简单、操作方便,但会引起压降,造成出口压力的非线性,通常,稳压精度在10%一20%。带指挥器作用的自力式控制阀可适用于小压降和大流量的自力式控制场合,出口压力变化范围可小于设定压力的10%。控制阀具有节能功能,因此,在一些控制要求不高的场合被广泛应用。自力式控制阀执行机构膜头的输入信号是控制阀前或阀后的压力或阀两端的压差,或经温包转换后的压力信号。执行机构的结构类似气动薄膜执行机构。控制阀对被控介质有一定要求,例如,自力式压力控制阀的被控介质温度应低于某一规定值,介质应干净,当介质温度较高时,例如,用于蒸汽或150℃以上的液体时,应设置冷凝器,使进入执行机构比较器内的介质温度低于规定值。
气动阀工作时,是利用弹簧的压力来调节、控制液压油的压力大小。从图3-50中可以看到:当液压油的压力小于工作需要压力时,阀芯被弹簧压在液压油的流入口,当液压油的压力过其工作允许压力即大于弹簧压力时,阀芯被液压油顶起,液压油流入,从图示方向右侧口流出,回油箱。液压油的压力越大,阀芯被液压油顶起得越髙,液压油经溢流阀流回油箱的流量越大o如过液压油的压力小于或等于弹簧压力,则阀芯落下,封住液压油进口。由于油泵输出的液压油压力固定,而工作油缸用液压油的压力要比油泵输出液压油压力小,所以正常工作时会有一些液压油从溢流阀处流回油箱,以保持液压油缸的工作压力平衡、正常工作。由此可见,直动式溢流阀的作用是能够防止液压系统中的液压油压力出额定负荷,起安全保护作用。
气动阀就属于这种类型的阀门,它包括旋启式止回阀和升降式止回阀。旋启式止回阀有一介铰链机构,还有一个像门一样的阀瓣自由地靠在倾斜的阀座表面上。为了确保阀瓣每次都能到达阀座面的合适位置,阀瓣设计在铰链机构,以便阀瓣具有足够有旋启空间,并使阀瓣真正的、全面的与阀座接触。阀瓣可以全部用金属制成,也可以在金属上镶嵌皮革、橡胶、或者采用合成覆盖面,这取决于使用性能的要求。
气动阀又被称为压力容器的终保护装置。安全阀根据工作压力能自动启闭,一般安装于封闭系统的设备或管路上保护系统安全。安全阀属于自动阀类,主要用于锅炉、压力容器和管道上,控制压力不过规定值,对人身安全和设备运行起重要保护作用。安全阀是一种安全保护用阀,它的启闭件受外力作用下处于常闭状态,当设备或管道内的介质压力升高,过规定值时自动开启,通过向系统外排放介质来防止管道或设备内介质压力过规定数值。当设备或管道内压力过规定值时,即自动开启泄压,保证设备和管道内介质压力在规定数值以内,防止发生事故。阀门自动开启,介质从中泄出、减压;当压力回到正常值时,弹簧压力又将阀芯推向阀座,阀门自动关闭。安全阀类的作用是防止管路或装置中的介质压力过规定数值,从而达到安全保护的目的。
气动阀则在阀内形成利用工作介质自身的控制回路,结构甚为简单。过去国内外电磁阀多项技术参数还受限制,现在国内电磁阀通径已扩展至30Omm;介质温度低至--200 ℃,高至450 ℃;工作压力从真空到25MPa。动作时间从十几秒到几毫秒。这些技术的新发展已完全可以取代原有体积庞大价格昂贵的两位控制的快速切断阀和气动开关阀,电动开关阀,也能部分取代连续调节的气动、电动调节阀。(怎样才能更好地满足调节精度要求,下文还要述及)。国外的纺织、轻工、城建等行业已大量改用电磁阀,而冶金、化工等行业则率先在辅助系统中使用越来越多的电磁阀。
气动阀旋启式止回阀在完全打开的状况下,流体压力几乎不受阻碍,因此通过阀门的压力降相对较小。升降式止回阀的阀瓣座落位于阀体上阀座密封面上。此阀门除了阀瓣可以自由地升降之外,其余部分如同截止阀一样,流体压力使阀瓣从阀座密封面上抬起,介质回流导致阀瓣回落到阀座上,并切断流动。根据使用条件,阀瓣可以是全金属结构,也可以是在阀瓣架上镶嵌橡胶垫或橡胶环的形式。
气动阀主要用于多泵并联使用时安装于水泵压出口,起限制水泵工作流量,防止停泵回流作用。该阀采用导阀,主阀构造,结构紧凑,重量较轻。该阀安装于水泵出口,在单泵启动和非全数设计工作泵工作时,对工作泵起限制流量作用,使泵在较高效率状态下工作;防止电动机在水泵低扬程、大流量、低效率时,发生过载现象;防止额定电流烧电机现象的发生,同时起到一定的节能效果。其限流原理为:依据水泵的设计工况点扬程,导阀自动检测并控制水泵的实际工作扬程,以限制水泵的工作流量,限制电机的负载。该阀设定一个控制工作扬程,当水泵工作扬程低于控制扬程时阀门做关阀动作,使实际工作扬程加大;当水泵工作扬程大于设定扬程时阀门全开,阀门阻力极小。控制扬程的设定可以按电机额定电流设定,也可以按高效率工况设定,该阀门工作扬程设定值可调,一般出厂设定值为设计工况扬程。
