DETAILED DESCRIPTION

[0020] The above and other technical contents, features and functions of the present invention are described in detail below with reference to the attached Figure 1-3 The detailed description of the embodiments will clearly show that the structural contents mentioned in the following embodiments are all based on the drawings in the specification.

[0021] Various exemplary embodiments of the present utility model will be described below with reference to the accompanying drawings.

[0022] Embodiment 1, a leakage detection and alarm device for an economizer, comprises an economizer body 1, a first pipeline 2 and a second pipeline 3, characterized in that:

[0023] The economizer body 1 is provided with a first pipeline 2, and the first pipeline 2 and the second pipeline 3 are both provided with a first flange 4 and a second flange 5, and the first flange 4 and the second flange 5 are connected by bolts 6;

[0024] The first flange 4 and the second flange 5 are provided with a detection housing 7;

[0025] The detection housing 7 is provided with a sealing ring 8 corresponding to the first flange 4, the detection housing 7 is provided with a matching hole 9 matched with the second pipe 3, and the detection housing 7 is provided with a monitor 10 and an alarm 11 matched with the detector;

[0026] The detection housing 7 is provided with an array of pressure plates 12 corresponding to the sealing ring 8 along the circumferential direction, and the pressure plate 12 is provided with a guide rod 13 slidably connected to the detection housing 7. An adjusting screw 14 is threadedly connected to the detection housing 7, and one end of the adjusting screw 14 is fixedly connected to an adjusting handle 15, and the other end is rotatably connected to the pressure plate 12.

[0027] Furthermore, the detector is located inside the detection housing 7 and corresponds to the gap formed by the first flange 4 and the second flange 5 , and the alarm 11 is located outside the detection housing 7 .

[0028] Furthermore, a sealing gasket is provided on the matching hole 9.

[0029] Furthermore, the sealing ring 8 is made of rubber.

[0030] Furthermore, the pressing plate 12 is arranged in an arc shape.

[0031] When in use, the first flange 4 and the second flange 5 are connected by bolts 6, so that the first pipeline 2 and the second pipeline 3 are connected. A sealing ring is provided between the first flange 4 and the second flange 5 to prevent gas leakage. Then the detection housing 7 is installed on the second pipeline 3, passes through the second pipeline 3 through the matching hole 9, and matches with the second flange 5. At the other end of the detection housing 7, the sealing ring 8 is made of rubber material. The sealing ring 8 is deformable and passes through the first flange 4 and the second flange 5. The sealing ring 8 is finally fitted with the outer wall of the first flange 4. The thickness from the sealing ring 8 to the bottom of the detection housing 7 is greater than the thickness of the first flange 4 and the second flange 5 by 1-2 cm.

[0032] After the sealing ring 8 is fitted with the first flange 4, the adjusting handle 15 is rotated to drive the adjusting screw 14 to rotate. Under the action of the guide rod 13, the pressing plate 12 moves to press the sealing ring 8 between the pressing plate 12 and the first flange 4. Since the detection housing 7 is provided with an array of pressing plates 12 along the circumferential direction, and the pressing plate 12 is arranged in an arc shape, when the array of pressing plates 12 moves to the limit position, the shape of the array of arc-shaped pressing plates 12 is infinitely close to the shape of a ring, so as to achieve a sealing effect;

[0033] The installation work is now completed. The monitor 10 is located in the gap formed by the first flange 4 and the second flange 5. If there is leakage in the gap, the alarm 11 will sound an alarm under the action of the monitor 10 to inform people.

[0034] This method is easy to install and disassemble, suitable for the detection of economizer leakage, and has simple operating steps, which is convenient for people to use.

[0035] The above description is only for illustrating the present invention, and it should be understood that the present invention is not limited to the above embodiments, and various variations that conform to the concept of the present invention are within the protection scope of the present invention.
