Application analysis of the flange spacer material

The valve is that various pipelines employ the essential apparatus, are used and reduced expenditure, broken inter-item transfer in various pipelines. But the flange connection of the valve is essential, it leaks the question of the thick liquid concerning the pipeline, it depends on the flange spacer in accordance with leaking the thick liquid that the flange is chained. At present, the commonly used flange spacer of valve has the following forms, among them interval of the flanges are different to some extent too: 1, The middle of the soft graphite compound spacer of compound spacer of soft graphite is 0.5mm thick carbon stencil plate or stainless steel board, there is soft graphite layer that is covered with on stencil plate, the total thickness is about 3mm. There is the certain one back to the elasticity after compressing in this kind of spacer, and will not cause the destruction of the spacer because of compressing tightly strength too big, there are certain intervals to hit the flange. 2,The rubbery asbestos board spacer rubbery asbestos board spacer is suitable for the operating modes of low pressure and water system. The deformation amount of this kind of spacer is small, the elasticity of going back is relatively bad. If use under the high-temperature operating mode, the bolt is influenced by temperature and extends, the spacer can’t compensate by its elasticity intervals produced, and only increase and compress tightly strength in making the flange keep sealed. Use this kind of spacer as the seal, there must be intervals in the flange. Also just because of adopting the habit of the rubbery asbestos board spacer for many years, make some applying unit no matter flange what material and form spacer adopt and require the flange to ask the crack without exception. In fact, the valve used in craft pipeline of petrochemical industry enterprises now has already basically no longer adopted the rubbery asbestos board spacer. 3,The metal wave form spacer metal wave form spacer is is pressed or rolled to press on the surface of the spacer and forms the ripple shape by the mild steel of about 0.8mm of thickness. After the spacer is compressed tightly, the flange reaches and seals in it is out of shape and makes from the crest. Because the spacer is very thin, its thickness is only about 0.5mm after being out of shape, can’t watch there are obvious intervals in the flange, basically belong to and has not asked the crack. 4,The twining spacer uses the twining spacer to let the flange not there is not interval in the valve is chained, may seem that there are intervals in appearance, but there is not interval. But realization of compression amount of the spacer that the sealed function of the twining spacer utilizes body of valve to stop the mouth and accuse of flying swiftly deeply. The compression amount of the twining spacer is generally 0.8- 1.2mm. In compressing tightly the structural design of the spacer, the thickness of the twining spacer is higher than the body of valve and stop the mouth deep 0.8- 1.2mm, among them after flange two level depend on urgent, spacer pigeonhole coiling up amount in the fixed range promptly at this moment. Under the intersection of operating mode and terms, vary with the temperature, seal than pigeonhole from spacer that the bolt extend and reduce, can be by the compensating back to the elasticity of the spacer, thus no leakage will take place in the flange spacer while guaranteeing.
