Description

Technical Field

[0001] The utility model relates to the technical field of municipal engineering, in particular to an anti-leakage connecting ring for a city gas transmission and distribution system. Background Art

[0002] Gas is a general term for gaseous fuels, which can burn and release heat for use by residents and industrial enterprises. There are many types of gas, mainly natural gas, artificial gas, liquefied petroleum gas, biogas, and coal-to-gas. Gas contains methane, which is harmless to human physiology, but has a suffocating effect. When its concentration in the air reaches 10%, it can cause suffocation and death. When the natural gas (methane) content in the air reaches 5-15%, it will explode when it encounters a fire source. However, in the prior art, during the gas transportation process, the connecting rings between the pipelines are aged due to moisture caused by rainwater, corroded due to acid contained in rainwater, weather reasons, biological reasons, leading to sealing problems, and then leakage occurs, causing danger. In view of this, we propose a leak-proof connecting ring for urban gas transmission and distribution systems. Utility Model Content

[0003] In order to make up for the above deficiencies, the utility model provides a leakage-proof connecting ring for a city gas transmission and distribution system.

[0004] The technical solution of the utility model is: comprising a connecting ring, characterized in that: an inert gas box is provided in the inner cavity of the connecting ring, a clamping sealing mechanism is also provided in the inner cavity of the inert gas box, sealing silicone layers are provided on both sides of the inert gas box, and a dehumidification box is provided on the side of the sealing silicone layer away from the inert gas box.

[0005] As a preferred technical solution, the clamping sealing mechanism includes a clamping silicone ring, and the clamping silicone ring is connected to the fixing block via a clamping spring.

[0006] As a preferred technical solution, the fixing block is fixed on the side wall of the inner cavity of the inert gas box.

[0007] As a preferred technical solution, the connecting ring includes two semicircular spheres with hinges at one end, and magnetic attraction layers are provided at the hinges and openings of the two semicircular spheres.

[0008] As a preferred technical solution, a buzzer is provided on the top of the connecting ring.

[0009] As a preferred technical solution, a leakage sensor is provided above the opening and closing portion of the two semicircular spheres.

[0010] As a preferred technical solution, the connecting ring clamps the gas conduit A and the gas conduit B which are spliced ​​at one end.

[0011] As a preferred technical solution, the clamping silicone ring clamps the outer edge ring of the connection between the gas conduit A and the gas conduit B.

[0012] As a preferred technical solution, the outer wall of the connecting ring is provided with a waterproof layer.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] By arranging a connecting ring around the gas conduit connection, the dehumidification box can isolate the moisture from the outer edge of the connecting ring. A sealing silicone layer is filled between the inner cavity of the connecting ring and the outer wall of the gas conduit, which can also achieve full fit between the sealing silicone layer and the outer wall of the gas conduit, reducing the space for gas flow. An inert gas box is arranged around the joint of the two gas conduits and filled with inert gas, which can effectively prevent the gas from flowing out of the joint. At the same time, a clamping sealing mechanism is also arranged around the joint of the gas conduits, which realizes double sealing with obvious effect. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] An inert gas box 3 is provided in the inner cavity of the connecting ring 1, and the inner cavity of the inert gas box 3 is filled with inert gas.

[0025] The inner cavity of the inert gas box 3 is also provided with a clamping and sealing mechanism 5 .

[0026] In this embodiment, the clamping sealing mechanism 5 includes a clamping silicone ring 51 , and the clamping silicone ring 51 is connected to a fixing block 53 via a clamping spring 52 .

[0027] In this embodiment, the fixing block 53 is fixed on the side wall of the inner cavity of the inert gas box 3 .

[0028] In this embodiment, the clamping silicone ring 51 clamps the outer edge ring 7 at the connection between the gas conduit A10 and the gas conduit B11.

[0029] It is worth further explaining that the clamping silicone ring 51 is semicircular, and the clamping spring 52 squeezes the clamping silicone ring 51 to clamp the outer edge ring 7 at the connection between the gas conduit A10 and the gas conduit B11. Since it is made of silicone material, it can surround the connection of the outer edge ring 7, and the silicone material is softer and more fit, and has higher sealing performance.

[0030] It is worth further explaining that an inert gas box 3 is arranged around the joint of the two gas conduits, namely the gas conduit A10 and the gas conduit B11, and is filled with inert gas, which can effectively prevent the gas from flowing out from the joint.

[0031] Sealing silica gel layers 4 are provided on both sides of the inert gas box 3 .

[0032] It is worth further explaining that the sealing silicone layer 4 can fill the space between the inner cavity of the connecting ring 1 and the outer walls of the gas conduits A10 and B11, thereby greatly improving the sealing performance.

[0033] A dehumidification box 2 is provided on a side of the sealing silica gel layer 4 away from the inert gas box 3 .

[0034] It is worth further explaining that the inner cavity of the dehumidification box 2 is provided with water-absorbing granular material to isolate the outer edge of the connecting ring 1 from moisture.

[0035] In this embodiment, the connecting ring 1 includes two semicircular spheres 13 with hinges at one end, and the hinges and openings of the two semicircular spheres 13 are provided with magnetic attraction layers 8.

[0036] It is worth further explaining that the magnetic attraction layer 8 is provided to better absorb and fit the two semicircular spheres 13 of the connecting ring 1 , thereby improving the airtightness of the connecting ring 1 .

[0037] In this embodiment, a buzzer 9 is provided on the top of the connecting ring 1 .

[0038] In this embodiment, a leakage sensor 12 is provided above the opening and closing portion of the two semicircular spheres 13 .

[0039] It is worth further explaining that when the leakage sensor 12 senses the gas leakage, the buzzer 9 sounds a buzzer alarm, and the power supply of these two components is provided by the solar cell matched with the buzzer 9.

[0040] In this embodiment, the connecting ring 1 clamps the gas conduit A10 and the gas conduit B11 which are spliced ​​at one end.

[0041] In this embodiment, a waterproof layer 6 is provided on the outer wall of the connecting ring 1 .

[0042] It is worth further explaining that the provision of the waterproof layer 6 is also to reduce the problem of moisture impact on the inner cavity of the connecting ring 1 .

[0043] When the utility model discloses a leak-proof connecting ring for a city gas transmission and distribution system, the gas conduit A10 and the gas conduit B11 are spliced ​​together, and then the clamping silicone ring 51 is used to clamp the outer edge ring 7 of the connection between the gas conduits A10 and B11, and the two semicircular spheres 13 of the connecting ring 1 are closed. The hinges and the openings of the two semicircular spheres 13 are provided with magnetic absorption layers 8, and the inner cavity of the dehumidification box 2 is provided with water-absorbing granular materials, so as to isolate the outer edge of the connecting ring 1 from moisture. The splicing part of the gas conduit A10 and the gas conduit B11 is located in the inner cavity of the inert gas box 3 and is filled with inert gas, so as to effectively prevent the gas from flowing out of the splicing part. At the same time, the clamping sealing mechanism 5 is also provided on the periphery of the splicing connection of the gas conduits, so as to achieve a significant leak-proof effect of the city gas waste transmission system and achieve double sealing.
