摘要:<p>A pressure relief device is provided. The pressure relief device includes a sealing member (22) and a low-pressure support member (24) that is adapted to provide support to the sealing member when the sealing member is subject to a certain pressure differential. The low pressure support member includes an annular flange (25) and at least one supporting projection (23). A cutting element (38) is adapted to puncture the sealing member when the sealing member is subject to a predetermined pressure differential. The pressure relief device may further include a high pressure support member (26) and safety heads (34,36) forming a pre-torqued assembly. The supporting projection may optionally include an area of weakness either wholly within or on the periphery thereof.</p>
