专利汇可以提供Support arrangement专利检索，专利查询，专利分析的服务。并且The invention provides a support arrangement for locating boiler or other service units in vertical bores in the pressure vessel wall of a nuclear reactor. The arrangement comprises two cooperating flanges (6) and (9) provided with grooves (10) and (11) respectively which are brought into alignment. The groove (10) houses pairs of wedge member segments (12), (13), which are moved radially outwardly of their groove by jacking screws (14) to a wedging position. Such an arrangement permits sealing between the unit and bore to be effected from the mouth end of the bore, thus permitting the seal to be readily renewed or serviced.，下面是Support arrangement专利的具体信息内容。

权利要求

1. A support arrangement for mounting a unit on wall means defining a bore, wherein the improvement comprises; the unit and said wall means each defining a cooperating groove; wedge shaped members disposed initiAlly in one of the grooves and comprising two cooperating slidably overlapped segmental rings which can be moved radially relative to each other so as to react against each other and take up a tight fit within the grooves; means for moving the wedge members partially out of said one groove so as to engage the other groove to provide axial location between the unit and said wall means while permitting relative radial movement therebetween; and sealing means for providing a fluid-tight seal between the unit and said bore, the sealing means being disposed with respect to the wedge members so as to be replaceable without moving the wedge members.

2. A support arrangement according to claim 1, wherein the sealing means comprises resilient O-section rings, the unit and said wall means each having defined in adjacent, co-planar, radial surfaces associated therewith, at least one channel in which a ring is disposed, there being provided a detachable annular cover plate which is pressed into sealing engagement with the rings.
