恒压阀作用是使储气筒维持在规定气压范围以内，当**过规定范围使空压机卸载，从而减小发动机动力损失恒压阀是阀门的一种类型，一般来说是作为主阀使用的，所以可以另外安装在管道上，还可以直接安装在主阀的盖子上。<br/>使用恒压阀的时候要注意哪些方面：<br/>1、恒压阀是一个比较精细的设备，要求准确度比较高，所以在平时使用的时候，一定要注意维护和保养；<br/>2、恒压阀在研制出来之后，都要通过严格的测试，才能够出厂销售；<br/>3、如果如果长时间没有使用恒压阀，再次使用之前，需要释放出阀内的压力，要不然就会导致零部件受损，以后就不能够再使用了。<br/><img style="margin: auto;clear: both;display: block" src="//l.b2b168.com/2022/05/10/09/202205100910292617074.jpg" alt="恒压阀生产厂家"/><br/>恒压阀如何调压力大小：<br/>1、在恒压阀上面有一个螺母，它就可以用来调节恒压的大小，把螺母调松调大了之后，之间的间隙也会扩大，受压就会变大，如果你把螺母拧紧了，就能够把恒压值调小；<br/>2、如果没有螺母，可以使用起子来进行调节，如果顺时针拧，压力就会变大，如果是逆时针来拧动，压力就会变小，其实就是根据调节它的弹簧力来调整压力值；<br/>3、恒压阀有两种类型，一种是正恒阀，如果把正恒阀关闭了，其实这时候压力就比较大，如果把反恒阀长时间打开，这时候压力就会变小。<br/><img style="margin: auto;clear: both;display: block" src="//l.b2b168.com/2022/05/10/09/202205100910271371364.jpg" alt="恒压阀生产厂家"/><br/>恒压阀安装时须注意以下事项:<br/>1、阀体部位一般不应拆卸，以免损坏或影响精度，调整压力时，卸下阀罩即可进行；<br/>2、应注意阀体所示流向，尤其是反恒阀的立式和横式要对照组装图仔细辨明、不能装错，否则将会失去控制作用；<br/>3、压力控制值应在原安装部位以系统的实际压力复调，取压部位宜加装压力表或压力表接口，以备调试时使用。<br/><img style="margin: auto;clear: both;display: block" src="//l.b2b168.com/2022/05/10/09/202205100910270583584.jpg" alt="恒压阀生产厂家"/><br/>恒压阀作用：<br/>1、使储气筒维持在规定气压范围以内，当**过规定范围使空压机卸载，从而减小发动机动力损失；<br/>2、出口管道上的单向阀用于防止液体回流，背压阀用于保持泵出口有一恒定压力；<br/>3、在要求不是很严格的系统中可作为安全阀使用；<br/>4、和脉动阻尼器配合使用减小水锤对系统的危害，减小流速波动的峰值，保护管路、弯头、接头不受压力波动的冲击；<br/>5、为计量泵创造良好的工作环境并改善泵的工作性能。<br/>我们厂秉承“以质量求生存，以信誉求发展”的经营理念，始终坚持以客户的需求和满意为核心，以诚信为宗旨，不断用精良、具有创造力的产品来回报客户。<br /><a href="http://rxwj.b2b168.com/">http://rxwj.b2b168.com</a>
