Apparatus to mechanically load a compression member
A compression generator uses a plurality of jackbolts threadedly engaged at a spaced apart relation about a bolt circle in a main core element. The main core element is releasable interlocked by threads, bayonet connection or other form of fasting system with the mounting element forming a fixed part of the mechanical connection. The jackbolts torqued to generate a pushing force in an axial direction for compressing a moveable part of the mechanical connection against a compression seat for forming a mechanical connection between juxtaposition fixed and moveable parts.
1. A compression generator assembly comprising:
a valve manifold;
a compression generator comprising:
a fixed part comprising a collar;
a moveable part comprising a valve;
a carrier comprising a round-shaped access plug and including threads on the external peripheral edge of said carrier for retained support by said fixed part and in a confronting relation to said moveable part, and
a plurality of jackbolts each received in one of a plurality of holes at spaced-apart locations about an outer peripheral part of said carrier;
wherein said collar is mounted against said valve manifold and which collar is releasably joined by threaded fasteners to said valve manifold, said collar having a central opening containing screw threads to receive the threads of said carrier; and
wherein said fixed part and said moveable part form a mechanical connection therebetween by transmitting a pushing force against a surface of said moveable part, and said jackbolts receive torque to generate said pushing force.
2. The compression generator assembly according to claim 1 further including a wrench grip provided by a hex nut member located in the central face area of said collar for torqueing said carrier during assembly and disassembly of the said carrier in said collar and centered on a side of said carrier directed away from said surface of said moveable part of said mechanical connection where friction is generated by transmitting said pushing force.
3. The compression generator assembly according to claim 2 further including an eyebolt assembly extending in said hex nut member and along said central opening in said collar.
