Description

Technical Field

[0001] This utility model relates to the field of detection technology, and in particular to a device for detecting the air leakage of an electric fire damper. Background Technology

[0002] When testing the air leakage of an electric fire damper, one end of the valve body is typically connected to an air inlet device with stable pressure and flow, while the other end is connected to a testing device. The air inlet device provides airflow at a certain pressure and flow rate, allowing the airflow to pass through the electric fire damper. The testing device then measures the amount of air leaking through the valve to assess whether the sealing performance of the electric fire damper meets the requirements. This connection method effectively simulates the airflow conditions of the valve in actual operation, accurately detecting the air leakage.

[0003] During the testing process, the valve body of the electric fire damper is typically connected to the air intake equipment and testing equipment via flange bolts or threaded connections. However, during equipment disassembly and assembly, it is necessary to tighten each bolt or threaded component for an extended period of time, which is a complicated process that significantly impacts work efficiency and hinders the efficient progress of the testing work.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-3 An electric fire damper leakage detection device includes a U-shaped base 1, an air inlet device 4, and a detection device 12. The air inlet device 4 is fixed to the right side of the base 1, and the detection device 12 is fixed to the upper end of the base 1. A rectangular support 2 is fixedly connected to the bottom inner part of the base 1 to support the valve body. The support 2 has a cavity for air circulation. The upper end of the support 2 has an opening communicating with the cavity for air circulation. Rubber pads 6 are fixedly connected to the upper end of the support 2 and the lower end of the pressure plate 7 to improve the sealing between the valve body and the pressure plate 7 and the support 2. The two rubber pads 6 have openings communicating with the through hole and the opening on opposite sides. A first pipe 3 communicating with the cavity is fixedly connected to the outer wall of the support 2 for air circulation. The end of the first pipe 3 away from the support 2 passes through the base 1 and is fixedly connected to the air inlet device 4. A first sealing ring 5 is fixedly sleeved on the first pipe 3 to improve the sealing between the first pipe 3 and the support 2. One side of the first sealing ring 5 is fixedly connected to the outer wall of the support 2.

[0022] In this embodiment, a horizontally arranged pressure plate 7 is slidably connected to the inner wall of the base 1 for pressing the valve body. Both ends of the pressure plate 7 are provided with arc-shaped grooves. Roller balls are rolled on the inner wall of the arc-shaped grooves to reduce the resistance when the pressure plate 7 is raised and lowered. The roller balls pass through the arc-shaped grooves. The pressure plate 7 is located above the support 2. The pressure plate 7 is provided with a through hole that is open from top to bottom for air circulation. The lower end of the through hole is vertically aligned with the opening. The upper end of the pressure plate 7 is fixedly connected to a second pipe 11 that is connected to the through hole for air circulation. The second pipe 11 is a telescopic flexible hose. The upper end of the second pipe 11 passes through the base 1 and is fixedly connected to the detection device 12. The lower end of the second pipe 11 is fixedly sleeved with a second sealing ring 13 to improve the sealing between the second pipe 11 and the pressure plate 7. The lower end of the second sealing ring 13 is fixedly connected to the upper end of the pressure plate 7.

[0023] In this embodiment, a plurality of vertically arranged guide rods 10 are fixedly connected to the upper end of the pressure plate 7, which are used to guide the pressure plate 7 to rise and fall. The upper end of the guide rod 10 slides through the base 1. A vertically arranged cylinder 8 is fixedly inserted into the inner top of the base 1, which is used to drive the pressure plate 7 to rise and fall. The upper end of the cylinder 8 passes through the base 1, and the lower end of the cylinder 8 is fixedly connected to the upper end of the pressure plate 7. Two fixing rings 9 are fixedly sleeved on the cylinder 8 to support the cylinder 8. The opposite sides of the two fixing rings 9 are fixedly connected to the inner top of the base 1 and the upper end of the pressure plate 7, respectively.

[0024] In this embodiment, firstly, the valve body is placed on the support 2, and the position of the valve body is adjusted so that its two ends are aligned with the opening and the through hole, respectively. Then, the cylinder 8 is activated, and the cylinder drives the pressure plate 7 to descend. The pressure plate 7 will firmly clamp the valve body, ensuring that both ends of the valve body are closed, thus ensuring that both ends of the valve body are connected to the through hole and the opening, respectively. At the same time, the rubber gasket 6 improves the sealing between the valve body, the pressure plate 7 and the support 2, preventing air leakage from affecting the accuracy of subsequent testing. At this time, the air intake device 4 is turned on, and the air intake device delivers air into the valve body through the first pipe 3, the cavity and the opening. If there is air leakage in the valve body, the leaked air will be delivered to the testing device 12 through the through hole and the second pipe in sequence. The testing device 12 then performs the air leakage test. After the test is completed, the cylinder 8 is activated again to raise the pressure plate 7, and the valve body can be easily removed, efficiently completing the quick clamping operation of the valve body.
