[0001] The utility model relates to the technical field of natural gas detection, and more specifically, to a leakage detection device for natural gas pipeline interfaces. Background Art

[0002] Natural gas refers to all gases that exist naturally in nature. The main components of natural gas are alkanes, among which methane accounts for the vast majority, and there are also small amounts of ethane, propane, and butane. In addition, there are generally hydrogen sulfide, carbon dioxide, nitrogen, water vapor, a small amount of carbon monoxide, and trace amounts of rare gases such as helium and argon. During the compression and processing of natural gas, natural gas needs to be transported and processed through various pipelines, and the pipelines are connected by flange plates. To ensure production safety, it is necessary to frequently detect whether the flange plates are leaking, so a leakage detection device for natural gas pipeline interfaces is required.

[0003] However, the prior art still has the following deficiencies: 1. When detecting a gas pipeline, it is not convenient to quickly install the detection device at the connection of the gas pipeline, so as to achieve rapid detection of the gas pipeline, which is not conducive to improving the convenience of use; 2. The existing detection devices are relatively single in use, and it is not convenient to detect whether there is leaked gas in the air when detecting a gas pipeline, which is not conducive to improving the diversity of use.

[0004] Therefore, there is an urgent need for a leakage detection device for natural gas pipeline interfaces to solve the above problems. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model.

[0025] As Figures 1-3As shown in the figure, this embodiment proposes a leakage detection device for natural gas pipeline interfaces, including a stretching plate 100 and a moving groove 101 opened on the side wall of the stretching plate 100. There are two groups of moving grooves 101 symmetrically arranged about the central axis of the stretching plate 100. A limiting groove 102 is opened on the side wall of the stretching plate 100. A moving block 103 is slidably connected to the side wall of the limiting groove 102. An adjusting groove 104 is opened on the side wall of the moving block 103. A group of linkage plates 105 are slidably connected to the side walls of the two stretching plates 100 through the adjusting groove 104. An automatic reset component is fixedly connected to the side wall of the linkage plate 105. A testing component for detecting the natural gas pipeline interface is connected to the side wall of the moving block 103. Through the linkage plate 105, the stretching plates 100 on both sides can be driven to move simultaneously, thereby improving the synchronization.

[0026] As Figures 1-4 shown, as a preferred embodiment, on the basis of the above method, further, the automatic reset component includes a connecting rod 110 fixedly connected to the side wall of the linkage plate 105. A tension spring 111 is sleeved on the outer wall of the connecting rod 110. One end of the connecting rod 110 passing through the stretching plate 100 is also fixedly connected with a pulling plate 112. The tension spring 111 facilitates the convenience of clamping at the pipeline interface.

[0027] As Figures 1-2 shown, as a preferred embodiment, on the basis of the above method, further, the testing component includes an arc plate 120 fixedly connected to the side wall of the moving block 103. A sealing pad 121 is fixedly connected to the side wall of the arc plate 120. There are two groups of sealing pads 121 symmetrically arranged about the central axis of the arc plate 120. A leakage detector 122 is fixedly connected to the inner wall of one group of arc plates 120. Since the material of the sealing pad 121 is relatively soft, the sealing performance can be further improved.

[0028] As Figures 1-5 shown, as a preferred embodiment, on the basis of the above method, further, a telescopic groove 123 is opened on the top wall of the arc plate 120. An air detector 124 is slidably connected to the inner wall of the telescopic groove 123. A support groove 125 is opened on the side wall of the air detector 124. A blocking block 126 is slidably connected to the side wall of the support groove 125. A first spring 127 is fixedly connected to the side wall of the support groove 125. One end of the first spring 127 away from the support groove 125 is also fixedly connected to the blocking block 126. A second spring 130 is fixedly connected to the inner wall of the telescopic groove 123. One end of the second spring 130 away from the telescopic groove 123 is also fixedly connected to the air detector 124. Through the cooperation of the blocking block 126 and the first spring 127, when the air detector 124 is pressed downward, the first spring 127 can push the blocking block 126 to slide into the mating groove 128 to realize the limitation of the air detector 124, making it more convenient to use.

[0029] As Figures 1-5As shown, as a preferred embodiment, on the basis of the above method, further, a fitting groove 128 is formed in the side wall of the arc-shaped plate 120, the blocking block 126 is fitted with the fitting groove 128, and an alarm 129 is fixedly connected to the top wall of the stretching plate 100. By providing the alarm 129, the determination of whether there is air leakage is realized, and the applicability is stronger.

[0030] Specifically, when the natural gas pipeline interface air leakage detection device of the present invention is in use: First, place the device at the position where it is needed, then loosen the pull plate 112, and under the action of the tension spring 111, drive the linkage plate 105 to reset through the connecting rod 110. When the linkage plate 105 moves, drive the moving block 103 to move towards the middle at the same time through the adjustment groove 104, thereby driving the arc-shaped plate 120 to contact the pipeline, realizing the clamping and closing of the pipeline. Then, use the air leakage detector 122 to detect whether there is air leakage at the pipeline interface. When there is an air leakage phenomenon, the alarm 129 is used to prompt the operator. When it is necessary to detect the gas in the air, push the blocking block 126 out of the fitting groove 128, thereby releasing the limit on the air detector 124, and eject the air detector 124 from the telescopic groove 123 through the second spring 130. Then, use the air detector 124 to detect whether there is gas in the air, thereby improving the diversity of use, and the air detector 124 can slide out of the telescopic groove 123 according to needs, thus not affecting the operation of the operator, and the practicability is stronger.

[0031] The above embodiments are only used to illustrate the present invention and do not limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above embodiments, the present invention is not limited to the above specific embodiments. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and their improvements that do not depart from the spirit and scope of the invention are covered by the scope of the claims of the present invention.
