摘要:
A sealing device is used in a flow control apparatus, the sealing device including a static seal and a protective seal or fluid restriction. The protective seal is formed between two members formed from resilient materials being substantially resistant to wear or failure when exposed to large pressure differentials and associated jetting action. The static seal is formed using a sealing element that includes a material that is at least partially deformable, such as an elastomer or the like. The protective seal is engaged prior to engaging or disengaging the static seal in order to prevent damage to the deformable material of the static seal.
