隔膜阀主要特点和原理

隔膜阀主要特点和原理

原文:
膜阀的主要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。隔膜阀中,由于工作介质接触的仅仅是隔膜和阀体,二者均可以采用多种不同的材料,因此该阀能理想地控制多种工作介质,尤其适合带有化学腐蚀性或悬浮颗粒地介质。   英标隔膜阀地工作温度通常受隔膜和阀体衬里所使用材料地限制,它的工作温度范围大约为-50~175度。隔膜阀结构简单,只由阀体、隔膜和阀盖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。操纵机构和介质通路隔开使隔膜阀不仅适用于食品和医药卫生工业生产,而且也适用于一些难以输送的和危险的介质。更多种人造合成橡胶和工程塑料的应用,以及更广泛地选择阀体衬里材料,使隔膜阀在现代工业的各个领域都得到广泛的应用。   隔膜阀分类   隔膜阀按结构形式可分为:屋式、直流式、截止式、直通式、闸板式和直角式六种;连接形式通常为法兰连接;按驱动方式可分为手动、电动和气动三种,其中气动驱动又分为常开式、常闭式和往复式三种。

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.
