Abstract
The present invention provides a tool kit for a heat exchanger and a method for detaching an end cover of a heat exchanger. The tool kit comprises: a first hinge device and a second hinge device, wherein the first hinge device and the second hinge device are mounted between an end flange and the end cover at a first position and a second position on the same axis, the first hinge device and the second hinge devices each comprising: a base, configured to be fixedly connected to the end flange; a rotating member, configured to be fixedly connected to the end cover; and a connecting member, configured to be detachably connected to the base and the rotating member, so that the rotating member is capable of rotating along the same axis relative to the base.
Claims18
A tool kit for a heat exchanger, wherein the heat exchanger comprises an end flange and an end cover mounted to the end flange, the tool kit comprising:
- at least a first hinge device and a second hinge device, wherein the first hinge device and the second hinge device are configured to be mounted between the end flange and the end cover at a first position and a second position on a same axis, the first hinge device and the second hinge devices each comprising:
- a base, configured to be fixedly connected to the end flange;
- a rotating member, configured to be fixedly connected to the end cover;
- a connecting member, configured to be detachably connected to the base and the rotating member, so that the rotating member is capable of rotating along the same axis relative to the base;
- and
- an abutting bolt for passing through a threaded hole of the base to press against the edge of the end flange or to press against one or more spacers arranged between the edge of the end flange and the base.
A tool kit for a heat exchanger, wherein the heat exchanger comprises an end flange and an end cover mounted to the end flange, the tool kit comprising:
- at least a first hinge device, wherein the first hinge device is configured to be mounted between the end flange and the end cover at a first position, the first hinge device comprises:
- a base, configured to be fixedly connected to the end flange;
- a rotating member, configured to be fixedly connected to the end cover;
- a connecting member, configured to be detachably connected to the base and the rotating member, so that the rotating member is capable of rotating along the same axis relative to the base;
- and
- an abutting bolt for passing through a threaded hole of the base to press against the edge of the end flange or to press against one or more spacers arranged between the edge of the end flange and the base.
A method for detaching an end cover of a heat exchanger, comprising:
- selecting a first position and a second position on a same axis close to an edge of an end flange;
- connecting bases of a first hinge device and a second hinge device to the end flange at the first position and the second position;
- connecting rotating members of the first hinge device and the second hinge device to the end cover at the first position and the second position;
- connecting, using connecting members, the bases and rotating members of the first hinge device and the second hinge device;
- rotating the rotating members of the first hinge device and the second hinge device along with the end cover along the same axis to open the end cover;
- and
- passing an abutting bolt through a threaded hole of the base to press against the edge of the end flange or to press against one or more spacers arranged between the edge of the end flange and the bases.
