目前余壓閥的結(jié)構(gòu)一般包括閥板、調(diào)節(jié)重錘、過濾網(wǎng)等幾個部分，工作時，閥板開啟一定角度，讓一定量的氣流通過。重錘在不同位置，閥板所受壓力不同，相同室內(nèi)壓力下，閥板的開啟度不同，可起到調(diào)節(jié)作用。

防靜電服采用專用滌綸長絲經(jīng)向或經(jīng)向緯向嵌織，經(jīng)特殊工藝制造而成，具有優(yōu)異、持久的導(dǎo)電性能。目前防靜電服廣泛用于醫(yī)藥、微電子、精密儀表、精密機械、食品工業(yè)、生命工程、精細化工等行業(yè)，是人員衣物防靜電的必要措施。
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.
防靜電服的功能會隨著穿用時間的增長而下降。在正常的室內(nèi)穿用情況下,凈化鋁材配件 http://www.jnjkjh.com/ 認為導(dǎo)致此類服裝功能下降的原因主要有以下三個方面:
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:
一是穿著過程中受到各種機械力的作用;二是洗滌;三是纖維的老化。其中前兩個方面的影響比較明顯,并會影響到穿著者的安全和所生產(chǎn)產(chǎn)品的質(zhì)量。穿著這類服裝從事作業(yè)時,人體在不斷地活動,防靜電服也隨著AMI壓力傳感器測試了在肘部關(guān)節(jié)活動狀態(tài)達到極限時(小臂和上臂夾角最小時),服裝肘部的受壓力情況。在服裝肘部受壓測試的基礎(chǔ)上,采用有限元分析方法確定和模擬防靜電服的張力分布情況,從而得出服裝肘部的極限受力情況。分析模型是基于極限活動狀態(tài)人體肘關(guān)節(jié)的表面狀態(tài)來決定的。
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，在使用防靜電服過程中，除了需要正確使用和定期養(yǎng)護之外，也要定期對防靜電服進行更換，以保證有效的工作。
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.
