The reasons for the better reasons, the sealing structure and working principle of the rubber O -shaped circle

The tight pine of the rubber O -type circle has always been an important information for the market. Its sealing, sealing structure and working principle.

The rubber O -ring has always been a key product in the domestic sealing equipment market, occupying a large part of the domestic market share. Naturally, this is indispensable with their own advantages. Generally speaking, the commonly used rubber O -ring structure in pump valve equipment is very simple, the production process is simple, and the cost is greatly reduced. Therefore, in practical applications, it can better adapt to installation and application requirements, and the disassembly is convenient. Therefore, with its better sealing ability, it has become a popular product in the seal market.

The rubber O -shaped ring is generally installed in the tube. If the design size is inaccurate and the specifications have deviations, because of a certain contraction, the surface layer of the rubber O ring groove may be incomplete, the sealing effect is not necessarily the best, or the rubber O ring contraction is too large. Pressure causes the rubber O ring to be directly destroyed, the sealing effect will be greatly reduced, and the cost of use will be greatly improved. In the sealing operation, rubber O -shaped rings often touch fuel. If the anticorrosive characteristics are poor, it is easy to be eroded by fuel, causing poor elastic characteristics, and then affecting the sealing effect. The more stress, the more deformation of the rubber O ring, the more the pressure on the sealing stage will gradually increase, and the more obvious the sealing effect will be, this is also an important reason for the well -sealing effect of the rubber O ring.
