膜片式电磁阀由于无滑动间隙、入口泄漏可控制在最小的适当值,导致导阀孔尺寸减少而使所需电磁力小,并降低了消耗功率和尺寸。它加工方便、压模成型、金属耗量小,以致结构简单、成本低、重量轻、维护量少。还有,它对介质的洁净度要求不高,适应面大。因此,它获得较广泛的应用。 在该类阀中,膜片式阀芯部件及其相关零件的配合是关键,特别是它们决定着耐久性。为此,在设计时应该注意下述一些问题。
Diaphragm-type solenoid valve due to no sliding gap, the inlet leakage can be controlled at a minimum appropriate value, resulting in reducing the size of the pilot valve hole so that the required electromagnetic force is small, and reduce the power consumption and size. It is easy to process, die-forming, metal consumption is small, so that the structure is simple, low cost, light weight, less maintenance. Also, it is less demanding media cleanliness, adaptation. Therefore, it is more widely used. In this type of valve, the cooperation of the diaphragm-type valve core components and their related parts is the key, in particular, they determine the durability. To this end, in the design should pay attention to the following questions.
