A gas manifold with gas leak detection function

Abstract

This utility model relates to the field of manifold technology and discloses a gas manifold with gas leak detection function. The novel solution includes a gas manifold, with a mounting cover fitted around the gas delivery pipe. An externally threaded connecting ring is integrally formed at the bottom of the mounting cover, and a sealing sleeve is screwed onto the outside of the externally threaded connecting ring. A magnetic ring is embedded at the bottom of the sealing sleeve. This utility model, by setting the mounting cover and sealing sleeve at the connection between the gas delivery pipe joint of the gas manifold and the mouth of the gas storage cylinder, completely covers the joint where it meets the mouth of the gas storage cylinder, forming a closed detection space. This confines the leaked gas to a small area. Combined with a concentration detection sensor on the mounting cover, it enables rapid detection and source location of leaks. Simultaneously, an independent audible and visual alarm is installed on the outside of the mounting cover to ensure that operators are alerted immediately to pinpoint the fault when a leak occurs.

Description

Technical Field

[0001] This utility model belongs to the field of manifold technology, specifically a gas manifold with gas leak detection function. Background Technology

[0002] In industrial gas transmission and manifold systems, gas leakage is a core risk threatening production safety, especially for flammable, toxic, or high-pressure gases, which can lead to serious consequences such as explosions, poisoning, and equipment damage. While traditional gas manifolds reduce the probability of leakage through optimized pipe connections and sealing structures, they lack targeted real-time monitoring and rapid response mechanisms. After a leak occurs, detection often relies on indirect methods using environmental sensors, resulting in issues such as response lag and ambiguous leak location, making it difficult to meet the demands of high-precision safety management. Therefore, we propose a gas manifold with gas leak detection capabilities. Utility Model Content

[0003] The purpose of this invention is to provide a gas manifold with gas leak detection function to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a gas manifold with gas leak detection function, comprising a gas manifold, an installation cover sleeved on the outer side of the gas delivery pipe of the gas manifold, an externally threaded connecting ring integrally formed at the bottom of the installation cover, a sealing sleeve screwed onto the outer side of the externally threaded connecting ring, a magnetic ring embedded at the bottom of the sealing sleeve, an audible and visual alarm and a concentration detection sensor installed on the left side of the installation cover, a pressure relief valve connected to the right side of the installation cover, the detection end of the concentration detection sensor penetrating through the left side of the installation cover and located inside the installation cover, a gas storage cylinder connected to the gas delivery pipe connector of the gas manifold, and the magnetic ring magnetically attracted to the top of the inner wall of the gas storage cylinder.

[0005] Preferably, the inner wall of the mounting cover is provided with a first annular groove, and a first sealing ring is installed in the first annular groove. The inner wall of the first sealing ring is in contact with the outer wall of the gas delivery pipe of the gas manifold.

[0006] Preferably, the top of the sealing sleeve is provided with an annular internal thread groove, the external thread connecting ring is screwed into the annular internal thread groove, and the bottom of the external thread connecting ring is provided with a second sealing ring, the bottom of the second sealing ring being in contact with the bottom of the annular internal thread groove.

[0007] Preferably, a third sealing ring is provided at the bottom of the sealing sleeve, and the bottom of the third sealing ring is in contact with the top of the outer side wall of the gas storage cylinder.

[0008] Preferably, the gas supply pipe connector of the gas manifold and the bottle opening of the gas storage cylinder are both located inside the mounting cover and sealing sleeve.

[0009] Preferably, a PLC controller is provided on the top of the gas manifold, and the PLC controller is electrically connected to the audible and visual alarm and the concentration detection sensor.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting an installation cover and a sealing sleeve at the connection between the gas pipe joint of the gas manifold and the gas cylinder mouth, the joint and the gas cylinder mouth are completely covered, forming a closed detection space, which confines the leaked gas to a small area. With the concentration detection sensor on the installation cover, the leak can be quickly detected and the source can be located. At the same time, an independent audible and visual alarm is set on the outside of the installation cover to ensure that the operator can be alerted to locate the fault point as soon as a leak occurs, which greatly improves the troubleshooting efficiency.

[0011] Since the sealing sleeve is fixed to the bottom of the mounting cover by an external threaded connecting ring, the device can quickly adapt to gas cylinders of different sizes by unscrewing the sealing sleeve and replacing it with a sealing sleeve of a different size.

[0018] 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.

[0019] Please see Figure 1-3 A gas manifold with gas leak detection function includes a gas manifold 1. A mounting cover 13 is sleeved on the outside of the gas supply pipe of the gas manifold 1. An external threaded connecting ring 19 is integrally formed at the bottom of the mounting cover 13. A sealing sleeve 14 is screwed to the outside of the external threaded connecting ring 19. A magnetic ring 21 is embedded at the bottom of the sealing sleeve 14. An audible and visual alarm 15 and a concentration detection sensor 16 are installed on the left side of the mounting cover 13. A pressure relief valve 17 is connected to the right side of the mounting cover 13. The detection end of the concentration detection sensor 16 passes through the left side of the mounting cover 13 and is located inside the mounting cover 13. The gas supply pipe connector of the gas manifold 1 is connected to a gas storage cylinder 11. The magnetic ring 21 is magnetically attracted to the top of the inner wall of the gas storage cylinder 11.

[0020] The inner wall of the mounting cover 13 has a first annular groove, and a first sealing ring 18 is installed in the first annular groove. The inner wall of the first sealing ring 18 fits against the outer wall of the gas delivery pipe of the gas manifold 1, sealing the connection gap between the mounting cover 13 and the gas delivery pipe of the gas manifold 1. The top of the sealing sleeve 14 has an annular internal thread groove, and an external threaded connecting ring 19 is screwed into the annular internal thread groove. After the external threaded connecting ring 19 is screwed into the annular internal thread groove of the sealing sleeve 14, the sealing sleeve 14 can be screwed and fixed to the bottom of the mounting cover 13. Then, the mounting cover 13 is moved upward along the gas delivery pipe of the gas manifold 1. Move the gas manifold 1 so that the gas supply pipe connector is removed from the mounting cover 13 and sealing sleeve 14. Then, connect the gas supply pipe connector of the gas manifold 1 to the mouth of the gas cylinder 11. Next, move the mounting cover 13 downwards along the gas supply pipe of the gas manifold 1, causing the sealing sleeve 14 to move downwards and contact the top of the outer wall of the gas cylinder 11. At this point, the magnetic ring 21 will be magnetically attracted to the gas cylinder 11, thus stably fixing the sealing sleeve 14 to the gas cylinder 11. This seals the connection between the gas manifold 1 and the gas cylinder 11 through the mounting cover 13 and sealing sleeve 14. If there is a leak at the connection between the gas manifold 1 and the gas cylinder 11... The leaked gas will remain inside the mounting cover 13 and the sealing sleeve 14. When the concentration sensor 16 detects the leaked gas inside the mounting cover 13 and the sealing sleeve 14, the audible and visual alarm 15 will sound an alarm. Simultaneously, if there is excessive leaked gas inside the mounting cover 13 and the sealing sleeve 14, causing excessive pressure, the pressure relief valve 17 will automatically release pressure to ensure stable pressure inside the mounting cover 13 and the sealing sleeve 14. A second sealing ring 2 is fixedly installed at the bottom of the external threaded connecting ring 19. The bottom of the second sealing ring 2 fits against the bottom of the annular internal thread groove, thus sealing the connection gap between the external threaded connecting ring 19 and the sealing sleeve 14. For sealing, a third sealing ring 22 is fixedly installed at the bottom of the sealing sleeve 14. The bottom of the third sealing ring 22 fits against the top of the outer wall of the gas storage cylinder 11, sealing the connection gap between the sealing sleeve 14 and the gas storage cylinder 11. The gas pipe connector of the gas manifold 1 and the bottle mouth of the gas storage cylinder 11 are both located inside the mounting cover 13 and the sealing sleeve 14. A PLC controller 12 is fixedly installed at the top of the gas manifold 1. The PLC controller 12 is electrically connected to the audible and visual alarm 15 and the concentration detection sensor 16, and controls the audible and visual alarm 15 and the concentration detection sensor 16 to work automatically through the PLC controller 12.

[0021] Working principle: The first sealing ring 18 seals the connection gap between the mounting cover 13 and the gas manifold 1 delivery pipe. After the external threaded connecting ring 19 is screwed into the annular internal thread groove of the sealing sleeve 14, the sealing sleeve 14 can be screwed and fixed to the bottom of the mounting cover 13. The second sealing ring 2 seals the connection gap between the external threaded connecting ring 19 and the sealing sleeve 14. The mounting cover 13 is moved upward along the gas delivery pipe of the gas manifold 1, so that the gas delivery pipe connector of the gas manifold 1 is removed from the mounting cover 13 and the sealing sleeve 14. At this time, the gas delivery pipe connector of the gas manifold 1 can be connected to the bottle mouth of the gas storage cylinder 11. Then, the mounting cover 13 is moved downward along the gas delivery pipe of the gas manifold 1, and the sealing sleeve 14 is moved downward to contact the top of the outer wall of the gas storage cylinder 11. At this time, the magnetic ring 21 will be magnetically attracted to the gas storage cylinder 11. The sealing sleeve 14 is stably fixed to the gas storage cylinder 11. The connection gap between the sealing sleeve 14 and the gas storage cylinder 11 is sealed by the third sealing ring 22. In this way, the connection between the gas manifold 1 and the gas storage cylinder 11 is sealed by the mounting cover 13 and the sealing sleeve 14. The PLC controller 12 controls the audible and visual alarm 15 and the concentration detection sensor 16 to work automatically. When there is a gas leak at the connection between the gas manifold 1 and the gas storage cylinder 11, the leaked gas will stay in the mounting cover 13 and the sealing sleeve 14. At this time, after the concentration detection sensor 16 detects the leaked gas in the mounting cover 13 and the sealing sleeve 14, the audible and visual alarm 15 can sound an alarm. At the same time, when there is too much leaked gas in the mounting cover 13 and the sealing sleeve 14, resulting in excessive pressure, the pressure relief valve 17 can automatically relieve pressure, thereby ensuring the pressure in the mounting cover 13 and the sealing sleeve 14 is stable.

[0022] Since the sealing sleeve 14 is screwed to the bottom of the mounting cover 13 by the external threaded connecting ring 19, the device can quickly adapt to gas cylinders 11 of different sizes by unscrewing the sealing sleeve 14 and replacing it with a sealing sleeve 14 of different sizes.
