A, inlet valve type O ring (O-ring) which features
1) simple structure, easy to manufacture, easy to install.
2) the frictional resistance is small and the dynamic and static friction is equal. It can eliminate the "crawling" phenomenon at low speed and low pressure.
3) good sealing, long working life, and the same life as the seal body under certain conditions.
4) it can be resistant to a variety of solvents, such as water, water vapor, oil, acid and alkali, gas, alcohol and so on.
5) good abrasion resistance, with automatic compensation function of elastic O-ring sealing surface wear.
6) it has good self lubrication performance and can be used as oil free lubrication seal.
1) working pressure in general,: 0-35MPa; speed: 15m/s; working temperature: -55-250 degrees.
Two, the valve import O type ring has many advantages and wide use
Specification size: inner diameter * line diameter;
Implementation standards: American Standard AS568, Japanese standard JIS2401-P, JIS2401-G and so on;
Material hardness: NBR70 Black;
Use temperature: Limit: -40~120 C, long term: -20~100 C;
Performance characteristics: good resilience seal, high temperature resistance, oil resistance, stable work in different medium, and long service life.
Widely used in gas or liquid medium, it can be used for a long time in all kinds of static and dynamic environments. The O sealing ring is usually installed in the groove of the outer circle or the inner circle which is rectangular in the groove. It is widely used in aerospace equipment, electronic and electrical appliances, agricultural machinery, sanitary ware, mining machinery, automobile, watch, ship and other industries.
