Abstract

The utility model relates to an installation structure of a tube sheet of a quick connection type shell and tube heat exchanger and belongs to the field of heat exchanger equipment commonly used in the industrial departments of chemical industry, petroleum, power, foods and the like. The installation structure mainly adopts a technical scheme that connecting threads are formed in a port of a single heat exchange tube, a connecting screw tube cap is additionally arranged and is a hollow screw tube, threads are formed outside the connecting screw tube cap and are matched with the threads in the port of the single heat exchange tube, and a cap-shaped body is arranged at the end part of the connecting screw tube cap. On the basis, the installation structure is shown as follows: the tube sheet is pressed by the port of the single heat exchange tube, the connecting screw tube cap penetrates through the tube sheet, the threads outside the connecting screw tube cap are screwed with the threads in the heat exchange tube, the tube sheet is pressed by the cap-shaped body of the connecting screw tube cap, and the hollow tube is connected with the heat exchange tube to be convenient for a heat exchange fluid medium to pass through, so that hundreds of heat exchange tubes are effectively connected with the tube sheet to avoid the welding difficulty and easily replace a single tube.

Description

A kind of fast-connecting type tubular heat exchanger tube sheet mounting structure
Technical field:
A kind of fast-connecting type tubular heat exchanger tube sheet mounting structure belongs to the general heat exchange equipment field of chemical industry, oil, power, food and other industrial department.
Background technology:
Heat exchanger is widely used in industrial departments such as chemical industry, oil, power, food, and as general equipment, traditional pipe heat exchanger adopts heat exchanger tube more; Heat exchanger tube is welded on the tube sheet, two kinds of different media respectively in manage with the pipe outflow heat exchange of coming because heat exchanger tube display need intensive being welded on the heat exchange tube sheet; Sometimes even will reach thousands of, thus these solder joints, if the rosin joint sealing-off; The equipment that influences is used, and the detection of single heat exchanging pipe is changed also inconvenient.
Summary of the invention:
Difficult for overcoming traditional tubular heat exchanger welding, change the difficult shortcoming of single heat exchanging pipe, a kind of fast-connecting type tubular heat exchanger tube sheet mounting structure is proposed at present; Its main implementation method is following: in single heat exchanging pipe port, open connecting thread; And establish connection screwed pipe cap in addition, said connection screwed pipe cap is a hollow screwed pipe, the peripheral hardware screw thread; Match with single heat exchanging pipe port internal thread, a cap-shaped body is established in its end.On this basis, this fast joint structure is such, and every single heat exchanging pipe port is pushed down tube sheet; Connect the screwed pipe cap and then pass tube sheet, its external screw thread and heat exchanging pipe internal thread are twisted and are closed, and its cap-shaped body is pushed down tube sheet; Its hollow pipeline and heat exchanging pipe link, and are convenient to the heat exchanging fluid medium and pass through, like this; Hundreds and thousands of heat exchanging pipes and tube sheet effectively link, and avoid the difficulty of welding, and are easy to change single tubulation.
The advantage of this structure is, has avoided the high strength welding processing process of heat transmission equipment, has reduced accident potential.
Description of drawings:
Accompanying drawing 1 is the said tubular heat exchanger structural representation of the utility model;
Accompanying drawing 2 is the said fast-connecting type tubular heat exchanger of the utility model tube sheet mounting structure sketch mapes;
Wherein: (1) heat exchanger body, (2) tube sheet, (3) heat exchanging pipe, (4) heat exchanging pipe port internal thread, (5) connect the screwed pipe cap, (6) cap-shaped body, (7) connect screwed pipe cap external screw thread.
The specific embodiment:
Like accompanying drawing 1, shown in 2, in single heat exchanging pipe (3) port, open connecting thread (4), other establishes and connects screwed pipe cap (5); Said connection screwed pipe cap (5) is a hollow screwed pipe; Peripheral hardware screw thread (7) matches with single heat exchanging pipe (3) port internal thread (4), and a cap-shaped body (6) is established in its end.On this basis, this fast joint structure is to use like this, and every single heat exchanging pipe (3) port is pushed down tube sheet (2); Connect spiral shell (5) pipe cap and then pass tube sheet (2), its external screw thread (7) is twisted with heat exchanging pipe (3) internal thread (4) and is closed, and its cap-shaped body (6) is pushed down tube sheet (2); Its hollow pipeline and heat exchanging pipe (4) link, and are convenient to the heat exchanging fluid medium and pass through, like this; Hundreds and thousands of heat exchanging pipes (4) and tube sheet (2) effectively link, and avoid the difficulty of welding, and are easy to change single tubulation.
