[0026] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings and specific embodiments.

[0029] The present utility model provides a remote alarm device for bursting disc actuation, which includes a slotted plate 1, and an upper gasket 2 and a lower gasket 3 are respectively arranged on the upper and lower sides of the slotted plate 1. A positioning ring 4 is arranged on the top surface of the slotted plate 1 inside the upper gasket 2, and a wire 5 is fixed through the positioning ring 4. The wire 5 is connected to an external cable.
[0030] The slotted plate 1 includes a disc-shaped slotted main board 11, in which a notch circular-ring-shaped through slot 12 coaxial with it is provided, and through slot stop holes 13 are arranged at both ends of the through slot 12. On the outer side of the slotted main board 11, a slotted plate connecting piece 14 is arranged at one end of the straight line between the two through slot stop holes 13 and the center point and the center of the circle, and a wire support piece 15 is arranged at the other end. The slotted plate connecting piece 14 is connected with a sign 16, and the performance parameters of the alarm device are displayed on the sign for customers to use.
[0031] The slotted plate 1 is made of a high-strength and high-temperature-resistant metal material. When an alarm occurs, it immediately acts and cuts off the wire 5 to achieve the purpose of alarm. The thickness of the slotted plate 1 is 0.2 mm to 0.8 mm. The diameter and width of the through slot 12 are determined according to different nominal pressures and different relief areas.
[0032] The upper gasket 2 and the lower gasket 3 are adhesively fixed to the slotted plate 1, which not only ensures the integrity of the overall structure but also ensures the superiority of performance. The upper gasket 2 contacts the upper flange on the site, and the lower gasket 3 contacts the upper clamp on the site, forming a soft and hard seal between them to ensure excellent sealing performance on the site. Two upward concave grooves 21 are arranged at the corresponding positions of the bottom surface of the upper gasket 2 and the wire support piece 15 for the wire 5 to pass through, effectively avoiding the risk of the wire 5 being broken due to extrusion.
[0033] The upper gasket 2 and the lower gasket 3 are both made of high-temperature-resistant and good-sealing-performance polymer materials, which can meet different working conditions on the site. The thickness of the upper gasket 2 and the lower gasket 3 is 0.5 mm to 5 mm, and the maximum use temperature is 500 °C. The outer diameters of the upper gasket 2 and the lower gasket 3 are the same as the outer diameter of the upper clamp, and the inner diameter determines the relief area according to the flange grade, which not only ensures sufficient relief flow but also ensures sufficient sealing area.
[0034] The positioning ring 4 includes a semi-circular positioning ring main body 41 protruding upward. Both ends of the positioning ring main body 41 are provided with positioning ring welding pieces 42 extending outward, and the two positioning ring welding pieces 42 are welded and fixed on the top surface of the slotted plate 1. After welding, the positioning ring 4 is placed inside the through slot 12, and the vertical plane where the welded and fixed positioning ring 4 is located coincides with the straight line between the center point and the center of the circle between the two through slot stop holes 13.
[0035] The wire 5 passes through the positioning ring body 41 of the positioning ring 4 and is fixed thereto. Both ends of the wire 5 after passing through are bent above the wire support piece 15. The wire 5 passes through the groove 21 of the upper gasket 2, and between the wire 5 and the wire support piece 15 outside the upper gasket 2, a heat shrinkable tube 51 is used for wrapping, so as to firmly fix the wire 5 and the slotted plate 1 together; at the same time, the two ends of the wire 5 are respectively connected to the on-site external wires, and the external wires are connected to the control room. When the wire breaks and cuts off the electrical signal, the control room receives the alarm signal immediately and conducts on-site maintenance, greatly reducing the material loss.
[0036] The wire 5 is made of a metal material and breaks immediately when subjected to a pressure impact, cutting off the signal and giving an immediate alarm; according to different pressure requirements, the wire 5 uses wires of different materials and different diameters. When subjected to pressure, the slotted plate flips upward until it breaks.
[0037] The bursting disc operation remote alarm device provided by the present utility model can also be processed according to the structure and size required by the user, and is applicable to all standard and non-standard flanges.
[0038] In addition, an integral body of the alarm device is formed among the slotted plate 1, the upper gasket 2, the lower gasket 3, the positioning ring 4, and the wire 5. The outer diameter of the alarm device is the same as the outer diameter of the upper clamp, which is convenient for on-site positioning and installation and saves costs.
[0039] The bursting disc operation remote alarm device provided by the present utility model solves the problem of non-alarm remotely, greatly shortens the time for leakage discovery, saves material costs and improves the operability of installation at the same time; the present utility model links the operation state of the bursting disc device with the control room and displays it on the large screen, intuitively reflecting the operation state of the on-site equipment. When the equipment has overpressure and causes the bursting disc device to burst, the control room can know immediately and replace the bursting disc device in time to minimize the material loss and avoid great waste of raw materials; the present utility model is simple to process, has low cost, can be processed according to the structure and size required by the user, and is applicable to all standard and non-standard flanges; during installation, it is convenient for positioning, greatly reduces costs, and improves the installation efficiency of the bursting disc device.
