T型结构隔膜阀的生产

在医药制造业中,无菌流程设备由许多水平管道和垂直管道组成,在制药设备的设计中,由于管道位置和技术方面的原因,必须在特定的位置安装使用这种波 纹管阀。例如,如果在垂直的管道中安装了隔膜阀,则须在同一水平面内经一个90°弯管的连接。而T型结构的隔膜阀的生产成本又很高,与不同阀体结构外形的 隔膜阀相比,波纹管阀则在体积和外形上,与管道的连接安装更具优势。由于两类截止阀的结构类型不同,因此,在无菌流程设备设计的初期,就应选择好各个部位 应选用哪种类型的截止阀。在医药、食品和生物技术领域中的输出设备有着大量的需要消毒的阀类。而大型的阀类,例如Stericom系列的,在这种需要消毒 的场合下几乎没有用武之地。因为,在这些流程设备中,要求输送的介质量越来越少,对于较少的流量,人们几乎无一例外地选择了隔膜阀。而新的波纹管阀有着较 小的体积,可以与不同的管道直径配用,在这方面比隔膜阀更具优势。T型结构隔膜阀的生产。

隔膜阀选用的试漏方法

阀门密封泄漏试压无论是使用新阀门,还是使用修复后的阀门,在安装前必须试压试漏。阀门试压,指的是阀体强度试验。试漏,指的是密封面严密性试验, 这两项试验是对阀门主要性能的检查。试验介质,一般是常温清水,重要阀门可使用煤油。安全阀定压试验,可使用氮气较稳定气体,也可用蒸汽或空气代替。对于 隔膜阀,使用空气作试验。一、阀门试验压力公称压力从0.4Mpa-32Mpa,这些常用压力阀门,阀门强度试验压力为其公称压力的1.5倍。阀门密封试 验压力,等于公称压力的1.1倍。二、阀门试验方法阀门的试压试漏,在试验台上进行。阀门试验台的结构,试验台上面有一压紧部件,下面有一条与试压泵相连 通的管路。将阀压紧后,试压泵工作,从试压泵的压力表上,可以读出阀门承受压力的数字。阀门试压充水时,要将阀内空气排净。试验台上部压盘,有排气孔,用 小阀门开闭。空气排净的标志是,排气孔中出来的全部都是水。关闭排气孔后,开始升压。升压过程要缓慢,不要急剧。达到规定压力后,保持3分钟,压力不变为 合格。阀门试压试漏三步骤:1、打开阀门通路,用水(或煤油)充满阀腔,并升压至强度试验要求压力,检查阀体,阀盖、垫片、填料有无渗漏。2、关死阀路, 在阀门一侧加压至公称压力,从另一侧检查有无渗漏。3、将阀门颠倒过来,试验相反一侧。隔膜阀选用的试漏方法。

什么叫隔离阀?

什么叫隔离阀?

原文:
隔离阀在真空系统中的作用:   1.开关气路,当阀1和阀4关闭,阀2打开时,机械真空泵Ⅲ对容器I抽真空,气流流经预真空抽气管路;当阀2关闭,阀4打开时,机械泵可单独对扩散泵抽真空;当阀1和阀4同时打开时,扩散泵和机械泵可同时工作,对容器进行抽空,此时气流流经扩散泵。可见,阀门在这种操作中的作用是开关气路,改变气流的流经路线。   2.控制气流大小,调节真空度在图1中,调节阀1的阀盖开启角度,即可调节流经管路的气流量大小;关闭阀2和阀4,通过放气阀3可以给机械泵Ⅲ的入口放成大气;通过放气阀5可以调节容器内的真空度。   3.定量充气,在玻璃阀的柱塞上有个一定体积的小洞,当小洞转向右边和高压气瓶连通时,小洞中就可充满高压气体;当它转向左边和真空容器连通时,就把该体积的高压气体放进容器中去,这样就起到了定量充气的作用。   真空阀门的种类繁多,通常按阀门的职能、结构型式、驱动方式、材料和用途进行分类。

译文:
Diaphragm valve main features and principles The main advantage of the membrane valve control mechanism and the media path are separated, not only to ensure the purity of the working media, but also to prevent the possibility of the media impact of pipeline control mechanism components. In addition, the stem Department does not require any form of individually sealed, except in the control of harmful media use as a safety facilities. Diaphragm valves, working media only contact with the diaphragm and the valve body, both of which can be used in many different materials, so the valve can be ideal to control a variety of working medium, is particularly suitable with a corrosive chemical or suspended particles to media. British standard diaphragm valve working temperature is usually subject to the diaphragm and body lining materials used to limit the operating temperature range of -50 to 175 degrees. The diaphragm valve of simple structure, assembly of three main components constitute only by the valve body, diaphragm, and valve cover. The valve is easy to fast disassembly and repair, and replacement of the diaphragm can be completed at the scene and within a short time. Control agencies and the media path separated from the diaphragm valve is not only applicable to the industrial production of food and medical and health, but also for difficult to transport and dangerous media. More man-made ​​synthetic rubber and engineering plastics applications, as well as wider choice body lining material, so that the diaphragm valve has been widely used in various fields of modern industry. Diaphragm valves Category Diaphragm valve structure can be divided into: housing type, DC type, globe type, straight-through, the ram type and the right angle six; connection usually in the form of flange connections; drive can be divided into manual, electric and pneumatic three The pneumatic drive is divided into the normally open, normally closed and reciprocating three kinds.
