Abstract

The invention discloses a chain type clamp for butt joint of vacuum flanges, a mounting tool and a mounting method of the chain type clamp. The chain type clamp comprises a chain which can be in buttjoint to form an annular shape, wherein the chain comprises a plurality of clamping clacks which are hinged to each other, a fixing part used for abutting against the mounting tool is arranged on theouter surface of each clamping clack, and fastening screw holes for butt joint are formed in the head end and the tail end of the chain. The method comprises the following steps that firstly, a sealing ring made of metal materials is inserted between two flange surfaces to be jointed; during mounting, each clamping clack of the chain type clamp is fixed through a fixing rod, and preset positioningis achieved; a mounting rod can carry a fixing bolt, and the fixing bolt can be screwed into the butt joint position of the clamping clacks, the sealing ring is extruded through the flanges to enablethe sealing ring to deform and fill the portion between the flange surfaces to realize sealing, so that the non-contact type mounting of the chain type clamp is completed, the operation is simple, and rapid mounting and dismounting can be realized conveniently in a high-radiation environment.

Description

technical field [0001] The present application relates to the field of accelerators, in particular to a chain clamp used for butt joint of vacuum flanges, an installation tool and an installation method thereof. Background technique [0002] In the field of particle accelerators, the connection of the vacuum system usually adopts a standard knife-edge flange structure, which has better safety and reliability. However, for high-current proton accelerators such as the China Spallation Neutron Source (CSNS), due to the large radiation dose, the replacement and repair of damaged parts must be completed in the shortest possible time after the equipment in the tunnel fails, so the pipeline connection , The connections at the pump port and so on are all chain-type quick-release devices. As a complex large-scale scientific research equipment, the particle accelerator is limited by physical and mechanical requirements, and the installation space in some areas is small. Therefore, it...
