Abstract
Description
Technical Field
[0001] The utility model relates to the field of sealing rings, in particular to a sealing ring for a gas pipeline. Background Art
[0002] Gas pipes are specialized conduits for transporting combustible gases. Metal gas pipe hoses replace traditional snap-on rubber hoses, addressing the drawbacks of rubber hoses, such as easy detachment, aging, insect bites, and a short service life. Two common methods are used to connect existing underground gas pipes. One is to weld the two pipes together; the other is to bolt the two pipes together and install an O-ring at the joint. However, existing sealing rings offer poor sealing performance and are in urgent need of improvement. Utility Model Content
[0003] The purpose of the utility model is to provide a gas pipeline sealing ring, which is used to solve the problem that the existing gas pipeline sealing ring has a poor sealing effect.
[0004] In order to solve the above problems, the utility model provides a gas pipeline sealing ring, including an outer ring and an inner ring, the inner ring is inserted between the first pipeline and the second pipeline, the outer ring is detachably sleeved on the outside of the first pipeline and the second pipeline, the inner ring includes a first connecting ring, a middle retaining ring and a second connecting ring in sequence, the first connecting ring is clamped in the first pipeline, the second connecting ring is clamped in the second pipeline, and the middle retaining ring is clamped between the flanges of the first pipeline and the second pipeline.
[0005] The utility model provides a gas pipeline sealing ring which also has the following technical features:
[0006] Furthermore, the outer ring is made of rubber.
[0007] Furthermore, the material of the inner ring is tetrafluoroethylene.
[0008] Furthermore, the outer ring includes a third connecting ring and a fourth connecting ring, and the third connecting ring and the fourth connecting ring are connected by bolts.
[0009] Furthermore, inner walls of the third connecting ring and the fourth connecting ring are provided with limiting grooves that cooperate with the flanges of the first pipeline and the second pipeline.
[0010] Furthermore, inner walls of the ends of the third connecting ring and the fourth connecting ring that are close to each other are provided with a groove that cooperates with the middle retaining ring.
[0011] The utility model has the following beneficial effects: the design of the inner ring and the outer ring can not only provide double protection for the joint between the first pipe and the second pipe, prevent gas leakage, and improve the sealing of the joint, but also the flange can prevent the outer ring and the inner ring from shifting, thereby improving the stability of the sealing ring installation, and the outer ring can also wrap the joint between the first pipe and the second pipe to avoid exposure to the outside and rusting to cause leakage, thereby further improving the sealing. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 2 It is a schematic diagram of the half-section structure of the gas pipeline sealing ring. DETAILED DESCRIPTION
[0014] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other.
[0015] like Figures 1 to 2 In the embodiment of a gas pipeline sealing ring of the present invention shown, it includes an outer ring 1 and an inner ring 2. The inner ring 2 is inserted between the first pipe 100 and the second pipe 101. The outer ring 1 is detachably sleeved on the outside of the first pipe 100 and the second pipe 101. The inner ring 2 includes a first connecting ring 21, a middle retaining ring 22 and a second connecting ring 23 in sequence. The first connecting ring 21 is clamped in the first pipe 100, the second connecting ring 23 is clamped in the second pipe 101, and the middle retaining ring 22 is clamped between the flanges 102 of the first pipe 100 and the second pipe 101. Specifically, the design of the inner ring 2 and the outer ring 1 can not only provide double protection for the joint between the first pipe 100 and the second pipe 101 to prevent gas leakage and improve the sealing of the joint, but also the flange 102 can prevent the outer ring 1 and the inner ring 2 from shifting, thereby improving the stability of the sealing ring installation. The outer ring can also wrap the joint between the first pipe 100 and the second pipe 101 to avoid exposure to the outside and rusting to cause leakage, thereby further improving the sealing.
[0016] In one embodiment of the present application, the outer ring 1 is made of rubber.
[0017] In one embodiment of the present application, the material of the inner ring 2 is tetrafluoroethylene.
[0018] In one embodiment of the present application, the outer ring 1 includes a third connecting ring 10 and a fourth connecting ring 11 , and the third connecting ring 10 and the fourth connecting ring 11 are bolted together.
[0019] In one embodiment of the present application, inner walls of the third connecting ring 10 and the fourth connecting ring 11 are provided with limiting grooves 1021 that cooperate with the flanges 102 of the first pipe 100 and the second pipe 101 .
[0020] In one embodiment of the present application, a groove 220 that cooperates with the middle retaining ring 22 is formed on the inner wall of the end where the third connecting ring 10 and the fourth connecting ring 11 are close to each other.
[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
