Description

Technical Field

[0001] This utility model relates to the field of pipeline inspection technology, and in particular to a leak-proof device for heating pipelines. Background Technology

[0002] Heating pipes are made up of several pipes connected in sequence. Adjacent pipes are usually connected by welding. Because the welds are corroded over a long period of time, they are prone to leakage. When the heating pipes leak during the heating season, it will affect the heating.

[0003] In the prior art, such as Chinese Patent No. CN221704778U, this utility model discloses a leak-proof device for heating pipes, relating to the field of heating pipe technology. It includes several sets of sealing components disposed on both sides of the weld between adjacent heating pipes. Each sealing component is detachably connected to a clamping component, which protects the weld. The clamping component includes a symmetrically arranged upper cover and a lower cover. Both ends of the upper and lower covers have protrusions fixedly connected. Two protrusions on the same side of the upper and lower covers are detachably connected by several bolts. The inner walls of the upper and lower covers are detachably connected to the sealing components. This utility model, through several sets of sealing components, enables the upper and lower covers to tightly abut against the heating pipes and isolates the weld from the external environment, preventing external environmental erosion and leakage, effectively extending the service life of the weld. This utility model has a simple structure, low manufacturing cost, and is easy to install and disassemble, facilitating weld maintenance during the non-heating season.

[0004] The above-mentioned solution can tightly assemble heating pipes through sealing components, preventing external environmental erosion of the welds and thus extending their service life. However, this technology still has certain shortcomings. The aforementioned heating pipe system lacks an effective real-time seal detection device, making it difficult to detect leaks at pipe joints, flanges, or welds in a timely manner. Once the leak-proof structure fails due to aging, corrosion, or stress deformation, the leak is often overlooked in its early stages, only becoming apparent when there is obvious dripping, pressure drop, or heat loss. This delayed detection not only exacerbates the leak but may also trigger secondary risks. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1, please refer to Figures 1 to 3This utility model provides a technical solution: a leak-proof device for heating pipes, including a retaining ring 101, a compartment 102 inside the retaining ring 101, a partition 103 fixedly installed near the bottom inside the compartment 102, a leak-proof component inside the compartment 102, the leak-proof component including a partition 2 104, the partition 2 104 fixedly installed inside the compartment 102, an air chamber 105 is formed between the partition 1 103 and the partition 2 104, and an air chamber 2 106 is formed between the partition 2 104 and the top, a slider 107 is slidably arranged inside the air chamber 105, a sliding rod 109 is fixedly installed on the top of the slider 107, and the sliding rod 109 is slidably arranged on the partition 2 106. Inside 104, a spring 108 is fitted on the outer surface of the slide bar 109. One end of the spring 108 is fixedly connected to the upper side of the slider 107, and the other end of the spring 108 is fixedly installed on the bottom of the partition 104. A trigger 110 is fixedly installed on the inner surface of the compartment 102. The partition 103 and the bottom of the retaining ring 101 form an air chamber 113. An air inlet 112 is opened at the center of the partition 103, and a vent 111 is opened on one side of the compartment 102. An alarm light 302 is fixedly installed on the outer surface of the retaining ring 101. Fixing parts 303 are fixedly installed at both ends of the retaining ring 101, and a rubber ring 301 is fixedly installed on the inner side of the retaining ring 101.

[0031] In this embodiment, during use, two retaining rings 101 are respectively installed on both sides of the pipe welding joint, and bolts are installed in the two fixing parts 303 to fix the two retaining rings 101. The inner ring of the retaining ring 101 is provided with a rubber ring 301, which can improve the sealing performance of the device. The retaining ring 101 has multiple compartments 102 inside, and the internal structure of the multiple compartments 102 is the same. When the pipe leaks, a large amount of steam will be sprayed out of the pipe. At this time, the steam will first enter the corresponding gas chamber 113 at the leak point. After the steam is collected, it is concentrated and sprayed into the gas chamber 105 through the air inlet 112. First, the steam will push the slider 107 to slide in the gas chamber 105, thereby pushing the top slider 109. The slider 109 slides upward and contacts the trigger 110, which can realize the alarm. When the alarm is triggered, the alarm light 302 on one side of the compartment 102 will be controlled to light up and sound an alarm, so that the staff can quickly locate the leak location.

[0032] Example 2, as Figure 4 The leak-proof assembly shown also includes a trigger 202, and an air chamber 4 203 is formed between the partition 103 and the top. A control fan 201 is fixedly installed inside the air chamber 4 203.

[0033] In this embodiment, gas enters the fourth gas chamber 203 through the air inlet 112. The steam simultaneously blows the two control fans 201, which rotate synchronously, thereby triggering the second trigger 202 to sound an alarm. The gas inside the fourth gas chamber 203 is discharged through the vent 111. This design, by setting the two control fans 201 to rotate synchronously to trigger the vent 111, can effectively avoid triggering the second trigger 202 by shaking a single control fan 201, thus improving the stability of the device.

[0034] Working principle: During use, two retaining rings 101 are installed on both sides of the pipe weld joint, and bolts are installed in the two fixing parts 303 to fix the two retaining rings 101. The inner ring of the retaining ring 101 is provided with a rubber ring 301 to improve the sealing of the device. The inside of the retaining ring 101 is provided with multiple compartments 102, and the internal structure of the multiple compartments 102 is the same. When the pipe leaks, a large amount of steam will be ejected from the pipe. At this time, the steam will first enter the corresponding air chamber 113 at the leak point. After the steam is collected, it is concentrated and injected into the air chamber 105 through the air inlet 112. First, the steam will push the slider 107 to slide in the air chamber 105, thereby pushing the top sliding rod 1. 09. When the slider 109 slides upward and contacts the trigger 110, an alarm is triggered. When the alarm is triggered, the alarm light 302 on one side of the compartment 102 will illuminate to help staff quickly locate the leak. Gas enters the gas chamber 203 through the air inlet 112. The steam blows the two control fans 201 at the same time. The two control fans 201 rotate synchronously, thereby triggering the trigger 202 to trigger the alarm. The gas inside the gas chamber 203 will be discharged through the vent 111. This design, by setting the two control fans 201 to rotate synchronously to trigger the vent 111, can effectively avoid the single control fan 201 rotating and triggering the trigger 202, thus improving the stability of the device.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
