Abstract
Description
Technical Field
[0001] This utility model belongs to the field of gas meter technology, specifically relating to a gas meter connector leak detection device. Background Technology
[0002] A gas meter is a device used to measure and record the amount of gas (such as natural gas, liquefied petroleum gas, etc.) used. From the outside, only a small glass window shows a digital dial with seven digits: the first four digits before the decimal point are black, and the last three are red.
[0003] The fuels people use for cooking have shifted from conventional energy sources like firewood and coal, which are wasteful and polluting, to cleaner energy sources like natural gas, coal gas, and even electricity. This is where gas meters come in. Their automatic accumulation function allows households using natural gas or piped coal gas to easily track their gas consumption and pay their bills based on the monthly gas consumption in cubic meters.
[0004] The gas meter is connected to the gas pipe via a connector. The connection point of the connector is prone to gas leakage, but the connector does not have automatic leak detection and cannot be monitored in real time. Utility Model Content

In the various figures, the same reference numerals denote the same or corresponding parts. The dimensions and scales in the various figures are also for illustrative purposes only and should not be construed as limiting the scope of the invention; these dimensions may be enlarged relative to actual products.
[0027] Reference Figure 1-3 The above describes a gas meter connector leak detection device, which includes a gas meter structure 1 and a connector leak detection structure 2 on the top of the gas meter structure 1.
[0028] The joint leak detection structure 2 includes two movable rings 201. A top sealing plate 206 is provided on the top of each movable ring 201. An auxiliary groove 212 is formed on the inner side of the top sealing plate 206. A threaded rod 209 is provided on the inner wall of the auxiliary groove 212. The threaded rod 209 is threadedly connected to the gas meter structure 1. A gas alarm 211 is provided on the outer wall of the threaded rod 209. Limiting grooves 203 are formed at the top and bottom of the outer wall of the movable rings 201. A positioning ring 204 is slidably connected to the inner wall of the 03. A slider 202 is provided at the bottom of the moving ring 201, and the slider 202 is slidably connected to the slide groove 105. A vertical groove 205 is opened on the inner side of the moving ring 201. A guide block 207 is provided on the outer wall of the top sealing plate 206, and the guide block 207 is slidably connected to the vertical groove 205. A sealing groove 208 is opened on the inner side of the top sealing plate 206, and the inner wall of the sealing groove 208 fits against the outer wall of the pipe interface 104. The top of the threaded rod 209... A slidable compression ring 210 is connected, with its bottom fitting against the top of the top sealing plate 206. Then, the slider 202 at the bottom of the moving ring 201 slides against the inner wall of the pipe interface 104. The two moving rings 201 fit together, and then the positioning ring 204 rotates, moving to the connection position between the two moving rings 201. The moving rings 201 then drive the top sealing plate 206 to move inward, and the sealing grooves 208 on the inner sides of the two top sealing plates 206 fit against the outer wall of the pipe interface 104. The two moving rings 201... A seal is formed between the threaded pipe 103 and the pipe interface 104 to prevent leaked gas from directly entering the outside air. When the two top sealing plates 206 are in contact, the inner wall of the auxiliary groove 212 is in contact with the outer wall of the threaded rod 209. Rotating the threaded rod 209 causes it to enter the top of the gas meter body 101, and the threaded rod 209 drives the compression ring 210 to move downward. The compression ring 210 pushes the top sealing plate 206 downward, and the bottom of the top sealing plate 206 is in contact with the outer wall of the pipe interface 104.
[0029] When a gas leak occurs, the gas alarm 211 installed on the outer wall of the threaded rod 209 detects the leak. At the same time, the joint leak detection structure 2 prevents gas from directly entering the air and performs a secondary seal at the joint position. Then, the gas alarm 211 sounds an alarm to remind personnel to check the joint position.
[0030] Furthermore, in the above technical solution, the gas meter structure 1 includes a gas meter body 101. A connection interface 102 is provided on one side of the top of the gas meter body 101. A threaded pipe 103 is provided on the top of the connection interface 102. A pipe interface 104 is provided on the top of the threaded pipe 103. The pipe interface 104 is threadedly connected to the threaded pipe 103. A sliding groove 105 is provided on the top of the gas meter body 101. The number of sliding grooves 105 is set to two, and the two sliding grooves 105 are symmetrically distributed on both sides of the connection interface 102. When it is necessary to check for leaks at the connection position between the connection interface 102, the threaded pipe 103 and the pipe interface 104 on the top of the gas meter body 101, it is only necessary to connect the pipe interface 104 on the top of the gas meter body 101 to the gas pipe and connect the pipe interface 104 to the threaded pipe 103 to allow gas to enter the interior of the gas meter body 101.
[0031] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
