Q:Which is better, the gasket?
Such as graphite composite pad, asbestos free pad, PTFE pad, winding pad and so on, rubber can also be.
Q:When designing a rubber O plain washer, how do you consider the width and thickness of the section?
You can refer to the following criteriaGB/T 3452.1-2005 hydraulic pneumatic O rubber seals - first dimensions: Dimensions and tolerancesGB/T 3452.2-2007 hydraulic pneumatic O rubber sealing ring second parts: appearance quality inspection specificationGB/T 3452.3-2005 hydraulic pneumatic O rubber seals - third dimensions: groove dimensions
Q:Sealing structure design
O ring is generally good. But in your drawing, the sealing ring is easy to damage, and you need to put on the washer. Change the position, in front of the thread.
Q:Is PTFE gasket poisonous to human body? Do I want to use it as a sealing ring in water cup?
PTFE gasket is also called PTFE or Teflon foreign gasket (Tie Fulong) gasket. By PTFE rods, tubes, plates or by mechanical cutting and turning the flat gasket, V shaped gasket, piston rings, valve gasket has corrosion resistance, anti-aging and good conductive properties.
Q:What's the difference between a sealing washer and an elastic washer?
As far as the distinction is concerned, from the model point of view, the O ring has a fixed model name. For example, 3.1*50., and gaskets have fixed models, such as oil seals, 45*60*7.
Q:Hydraulic joint with copper and aluminum gasket than rubber gasket will be more durable, sealing performance will be better?
Imported generally coated with sealant, so after opening and then installed on the die
Q:The sealing principle of metal wound gasket?
Sealing gasket: metal winding principle of the sealing surface when the pressure load, to produce compressive stress, can improve the sealing contact surface, when the stress increases enough to cause the surface of the plastic deformation obviously, it can fill the gap seal cover, plug leakage channel. The purpose of using the gasket is to use the gasket material to produce plastic deformation characteristics under the action of compaction load so as to fill the small and uneven surface of the flange sealing surface so as to realize the sealing.Leakage is the phenomenon that the medium enters the limited space from the outside of the inner space of the limited space or from the outside. This is what people do not want to happen. The medium flows through the interface between the inside and outside spaces, i.e., leaks occur on the sealing surface. The root cause of the leakage is that there is a gap in the contact surface, and the pressure difference and the concentration difference on both sides of the contact surface are the driving force of the leakage. Because of the sealing surface form and processing accuracy and other factors, the sealing surface of the gap is unavoidable, which will cause the sealing surface is not completely consistent, resulting in leakage.In order to reduce the leakage, it is necessary to make the contact surface to be fitted to the maximum extent, that is to reduce the cross-sectional area of the leakage passage and to increase the leakage resistance, and to make it larger than the leakage force. In the bolt flange gasket connection, the force of the gasket causes deformation of the gasket material so as to fill the gap between the flange sealing surfaces. The magnitude of its pretension depends on the number of bolts, the torque of the tightening bolt, the lubrication state of the bolt system, and the compression area of the gasket.
Q:PTFE gasket and stainless steel plane sealing problem 5
An end face groove shall be machined at the same location of the housing and the plug, and the side of the slot requires Ra0.4. Fit the PTFE pad in the slot. The thickness of the pad is greater than the sum of two of the groove depth.
Q:Hello, I'd like to ask about the gasket used in the petrochemical industry. What about rubber or asbestos?
Hello, I'd like to ask about the gasket used in the petrochemical industry. What about rubber or asbestos?Gasket
Q:What sealed products are used in refineries?
The most high-end seal in the refinery is perfluorinated rubber seals, as well as some high temperature resistant fluorine rubber and O rings, U rings, rubber gaskets, PTFE, PTFE and other seals
