‘0821100013气动压力开关

气动阀优点

1、气动装置结构简单、轻便、安装维护简单。介质为空气，较之液压介质来说不易燃烧，故使用安全。

2、工作介质是取之不尽的空气、空气本身不花钱。排气处理简单，不污染环境，成本低。

3、输出力以及工作速度的调节非常容易。气缸的动作速度一般小于1M/S，比液压和电气方式的动作速度快。

4、可靠性高，使用寿命长。电器元件的有效动作次数约为百万次，而一般电磁阀的寿命大于3000万次，某些质量好的阀超过2亿次。

5、利用空气的压缩性，可贮存能量，实现集中供气。可短时间释放能量，以获得间歇运动中的高速响应。可实现缓冲。冲击负载和过负载有较强的适应能力。在一定条件下，可使气动装置有自保持能力。

6、全气动控制具有防火、防爆、防潮的能力。与液压方式相比，气动方式可在高温场合使用。

7.压缩空气可集中供应，远距离输送。

性能要求

1.阀门某一规格批量制造时，应委托有地位性机构进行以下性能的：

①阀门在工压状况下的启闭力矩；

②在工压状况下，能保证阀门关闭严密的连续启闭次数；

③阀门在管道输水状况下的流阻系数的。

2.阀门在出厂前应进行以下的：

①阀门在开启状况下，阀体应承受阀门工压值二倍的内压；

②阀门的关闭状况下，两侧分别承受1.1倍阀门工压值，无渗漏；但金属密封的蝶阀，渗漏值亦不大于相关要求。

压力开关是一种简单的压力控制装置，当被测压力达到额定值时，压力开关可发出警报或控制信号。压力开关的一般工作原理：是当系统内压力高于或低于额定的安全压力时，感应器内膜片片瞬时发生移动，通过连接导杆推动开关接头接通或断开，当压力降至或升额定的恢复值时，膜片瞬复位，开关自动复位，或者简单的说是当被测压力超过额定值时，弹性元件的自由端产生位移，直接或经过比较后推动开关元件，改变开关元件的通断状态，达到控制被测压力的目的。

压力开关用在空压机上面主要是来调节空压机的起停状态,通过调节储气罐内的压力来让空压机停机休息,对机器有保养作用.在空压机工厂调试的时候,根据客户需要调节到指定压力,然后设定一个压差.例如,压缩机开始启动,向储气罐打气,到压力10kg的时候,空压机停机或者卸载,当压力到7kg的时候空压机又开始启动,此间有一个压力差,这个过程就可以让压缩机休息一下,达到保护空压机的作用.由电动机直接驱动压缩机，使曲轴产生旋转运动，带动连杆使活塞产生往复运动，引起气缸容积变化。由於气缸内压力的变化，通过进气阀使空气经过空气滤清器（****）进入气缸，在压缩行程中，由於气缸容积的缩小，压缩空气经过排气阀的作用，质量流量计经排气管，单向阀（止回阀）进入储气罐，当排气压力达到额定压力0.7MPa时由压力开关控制而自动停机。
