introduction： 1、OHardness of the ring OThe hardness of the ring material is the most important index to evaluate the sealing performance。Hardness determinesOThe compression amount of the ring and the maximum allowable extrusion clearance of the groove。Due to ShawA70The Ding Qing seal can meet most of the conditions of use，Therefore, there is no special explanation for the sealing material，Generally offered by ShawA70The butadiene rubber。 2、Extrusion clearance Maximum permissible extrusion clearancegmaxAnd system pressure、OThe diameter of the ring section is also related to the hardness of the material。usual，The higher the work pressure，Maximum permissible extrusion clearancegmaxThe smaller the value is。If gapgOut of bounds，Will lead to
