Title:
成形パッキング要素を備えた制御弁
Document Type and Number:
Japanese Patent JP2009530548
Kind Code:
A
Abstract:
Control valve with profiled packing element for making bidirectional flow-through with asymmetric intensity possible in a flow area. The packing element (1) has a first surface which can be abutted against a second surface in the valve housing (2). The packing element (1) has a first position in which said first surface (3) and said second surface (4) abut against one another, and a second position in which said first surface (3) and said second surface (4) are distant from one another. At least one of the surfaces (3, 4) is provided with a damage (5) by means of which when said packing element (1) is in its first position a first cross-section of flow is ensured between said abutting first and second surfaces (3, 4), which is smaller than a second cross-section of flow ensured by said packing element (1) when it is in its second position.
