　　进口真空隔膜阀
Orsen型－高真空隔膜阀
真空隔膜阀是利用阀杆将橡胶膜直接压在阀座上，用来截止或接通真空系统。采用连接形式有活套法兰连接、快卸法兰连接、焊接式连接。焊接式连接又分焊接式I型连接〔即两端焊接〕，焊接式II型连接〔即 一端焊接，另一端插入〕。阀门适用的工作介质为空气及非腐蚀性气体。
进口真空隔膜阀是在阀体和阀盖内装有一挠性隔膜或组合隔膜，其关闭件是与隔膜相连接的一种压缩装置。阀座可以是堰形，也可以是直通流道的管壁。隔膜阀的优点是其操纵机构与介质通路隔开，不但保证了工作介质的纯净，同时也防止管路中介质冲击操纵机构工作部件的可能性。此外，阀杆处不需要采用任何形式的单独密封，除非在控制有害介质中作为安全设施使用。它的工作温度范围大约为－50～175℃。隔膜阀结构简单，只由阀体、膜片和阀头组合件三个主要部件构成。该阀易于快速拆卸和维修，更换隔膜可以在现场及短时间内完成。
Vacuum diaphragm is the use of stem rubber membrane pressed directly on the seat, or to turn off the vacuum system. Using connections in the form of loose flange connection, quick release flange connection, welded connection. Welded connection is divided welded I-type connectors at both ends [ie] welding, welded connection type II [ie welding end and the other end into]. Valve suitable working medium for air and non-corrosive gases.
Imported vacuum diaphragm valve body and bonnet are built with a flexible diaphragm or a combination of the diaphragm, the closure member is a compression device connected to the diaphragm. The seat can be shaped weir, the flow channel may be a straight wall. Advantages diaphragm is separated from its operating mechanism and media access, not only to ensure the purity of the working medium, but also prevent the possibility of the impact of the pipeline to manipulate the media agency working parts. In addition, stem Department does not require any form of individually sealed, unless in the control of harmful use media as a security facility. Its operating temperature range of about -50 ~ 175 ℃. Simple diaphragm structure consists only of the body, diaphragm and valve head assembly of three main components. The valve is easy to quickly disassemble and repair, replacement of the diaphragm can be done on-site and in a short time.
