目前余压阀的结构一般包括阀板、调节重锤、过滤网等几个部分,工作时,阀板开启一定角度,让一定量的气流通过。重锤在不同位置,阀板所受压力不同,相同室内压力下,阀板的开启度不同,可起到调节作用。

防静电服采用专用涤纶长丝经向或经向纬向嵌织,经特殊工艺制造而成,具有优异、持久的导电性能。目前防静电服广泛用于医药、微电子、精密仪表、精密机械、食品工业、生命工程、精细化工等行业,是人员衣物防静电的必要措施。
 
Anti - static clothing is made of special process, which is made of special process, which is made of polyester filament warp or weft insertion. At present, anti-static clothing is widely used in medicine, microelectronics, precision instruments, precision machinery, food industry, life engineering, fine chemicals and other industries, is the necessary measures to prevent static electricity.
 
防静电服的功能会随着穿用时间的增长而下降。在正常的室内穿用情况下,净化铝材配件 http://www.jnjkjh.com/ 认为导致此类服装功能下降的原因主要有以下三个方面:
 
The function of anti - static clothing will decrease with the increase of time. Under normal indoor wear condition, the purification of aluminum fittings is considered to be the main reason for the decrease of the function of this kind of clothing. There are three main aspects:
 
一是穿着过程中受到各种机械力的作用;二是洗涤;三是纤维的老化。其中前两个方面的影响比较明显,并会影响到穿着者的安全和所生产产品的质量。穿着这类服装从事作业时,人体在不断地活动,防静电服也随着AMI压力传感器测试了在肘部关节活动状态达到极限时(小臂和上臂夹角最小时),服装肘部的受压力情况。在服装肘部受压测试的基础上,采用有限元分析方法确定和模拟防静电服的张力分布情况,从而得出服装肘部的极限受力情况。分析模型是基于极限活动状态人体肘关节的表面状态来决定的。
 
One is wearing the process of being subjected to a variety of mechanical force; the two is the washing; three is the aging of the fiber. The first two aspects of the impact is obvious, and will affect the wearer's safety and the quality of the product. Wearing this kind of clothing in the work, the human body in constant activity, anti static clothing also with the AMI pressure sensor test in the elbow joint activity state reached the limit (the small arm and the upper arm angle of the most hours), clothing elbow pressure. On the basis of the test of the compression test of the clothing, the finite element analysis method is used to determine and simulate the tension distribution of the anti - static clothing. The analysis model is based on the surface state of the human elbow joint in the limit state.
 
因此,在使用防静电服过程中,除了需要正确使用和定期养护之外,也要定期对防静电服进行更换,以保证有效的工作。
 
Therefore, in the use of anti-static clothing, in addition to the need for proper use and regular maintenance, but also on a regular basis for the anti - static clothing to be replaced, to ensure effective work.
