Description

Technical Field

[0001] The utility model relates to the technical field of gas pipeline blocking, in particular to a municipal gas pipeline blocking device. Background Art

[0002] Gas pipeline leakage is a serious hazard and may cause fire, explosion, casualties and property losses. Leaked gas can also cause poisoning and threaten human health. At the same time, leakage also leads to energy waste and environmental pollution. Therefore, once a gas pipeline leak is found, measures must be taken immediately to seal and repair it to ensure personnel safety, reduce economic losses and protect the environment.

[0003] The utility model with the authorization publication number CN220566863U provides a pipeline plugging device for municipal gas engineering, which belongs to the technical field of "gas pipeline plugging". The protected claim is: "It includes a pair of clamping rings and a plugging plate, and the two ends of the clamping ring are fixedly provided with fixing plates. The fixing plates on the two clamping rings are connected by bolts and nuts. The inner side of the plugging plate is connected with a sealing gasket, and the outer side of the plugging plate is fixedly connected with a rotating shaft. Two spring telescopic rods and an internal threaded sleeve are arranged between the two fixing plates at the same end of the two clamping rings. Both ends of the internal threaded sleeve are connected to the spring telescopic rod. The internal threaded sleeve is located in the middle of the two fixing plates. One end of the spring telescopic rod is connected to the internal threaded sleeve, and the other end of the spring telescopic rod is connected to the fixing plate. A threaded shaft is matched and connected in the internal threaded sleeve, and the inner end of the threaded shaft is rotatably connected to the rotating shaft. Through the arrangement of the spring telescopic rod, the internal threaded sleeve, the threaded shaft, the rotating shaft, the plugging plate and the sealing gasket, the leaking part of the gas pipeline can be quickly plugged."

[0004] In this device, although the leakage of the gas pipeline can be blocked, the device does not strengthen the blocking of the leakage, and does not strengthen the entire section of the pipeline around the leakage. The section of the pipeline around the leakage is relatively fragile and is not strengthened, so it is easy to break and leak again. For this reason, we propose a municipal gas pipeline blocking device. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0023] Embodiment 1

[0024] like Figure 1-4As shown, in this embodiment, a municipal gas pipeline plugging device includes an outer hoop tube 101, a rotating hoop 104 and a second screw 112. The outer side of the outer hoop tube 101 is provided with a first hoop ring 102, and one side of the first hoop ring 102 is provided with an empty groove 103; the rotating hoop 104 is slidably connected in the empty groove 103, one end of the rotating hoop 104 is rotatably connected to a rotating shaft 105, the bottom end of the rotating shaft 105 is fixedly connected to a connecting rod 106, and the bottom end of the connecting rod 106 is fixedly connected to the first screw 10 7. A slot 108 is provided at the bottom end of the first hoop 102, and the first screw 107 is movably connected in the slot 108. The external thread of the first screw 107 is connected to the first rotating wheel 109. A slide groove 110 is provided on the inner side of the rotating hoop 104, and a blocking block 111 is slidably connected in the slide groove 110. The second screw 112 is threadedly connected to the upper end of the first hoop 102, and the bottom end of the second screw 112 is fixedly connected to the back plate 113, and the upper end of the second screw 112 is fixedly connected to the second rotating wheel 114.

[0025] During specific implementation, a sealing ring 117 of different shapes is selected according to the shape of the leakage gap. For example, a circular sealing ring 117 is selected for a circular gap, and then the sealing block 111 stained with the sealing ring 117 is inserted into the slide groove 110, and then the outer hoop 101 is put on the outside of the pipeline, and then the first screw 107 is loosened, and the first hoop ring 102 and the rotating hoop 104 are put on the outside of the outer hoop 101, aligned with the position of the gap, and then the first screw 107 is inserted into the slot 108, and it is tightened by the first rotating wheel 109, so that the pipeline can be initially tightened, and then the second screw 112 is tightened by the second rotating wheel 114, and the second screw 112 drives the abutment plate 113 to tighten the rotating hoop 104, so that the gap can be tightened at the upper end of the gap to strengthen the sealing, and at the same time, the role of the sealing ring 117 in adapting to the shape of the gap can enhance the effect.

[0026] In addition, it should be noted that the limiting wheel 116 acts as a fulcrum when the rotating hoop 104 rotates. At the same time, there is a gap between the limiting wheel 116 and the outer side of the empty slot 103, which can play a limiting role when the rotating hoop 104 is pressed and moved downward.

[0027] Furthermore, a stop block 115 is fixedly connected to the top of the first rotating wheel 109, and the stop block 115 is threadedly connected to the outside of the first screw 107. By setting the stop block 115, when the first rotating wheel 109 rotates, the stop block 115 can be driven to rotate synchronously to tighten the rotating hoop 104 and the first hoop ring 102.

[0028] Furthermore, the outer hoop tube 101 and the sealing ring 117 are made of rubber material. The main function of the rubber outer hoop tube 101 and the sealing ring 117 at the leakage port of the gas pipeline is to provide excellent sealing performance to prevent gas leakage. At the same time, due to its elasticity and adaptability, it can fit tightly to leakage ports of different shapes and sizes to ensure the sealing effect. In addition, rubber also has good temperature resistance and chemical corrosion resistance, ensuring the stability and reliability of the sealing component during long-term use.

[0029] Embodiment 2

[0030] On the basis of the first embodiment, in order to make up for the problem that a section of the pipe around the leaking part in the first embodiment is relatively fragile and not reinforced, and is easy to break and leak again, a second hoop 201, a notch 202, a third screw 203 and a third rotor 204 are provided.

[0031] like Figure 1-2 As shown, the outer sleeve of the outer hoop tube 101 is provided with a second hoop ring 201, and slots 202 are provided at both ends of the second hoop ring 201. A third screw 203 is rotatably connected in one slot 202, and the upper end of the third screw 203 is clamped in another slot 202. The outer thread of the third screw 203 is connected to a third rotating wheel 204.

[0032] During the specific implementation, the second hoop ring 201 is put on both ends of the outer hoop tube 101, and then the third screw 203 is inserted into the slot 202, and then the third rotating wheel 204 is rotated to tighten the second hoop ring 201, that is, to tighten the two ends of the outer hoop tube 101, so as to avoid the problem of leakage due to the fragility of a section of the pipe around the gap.

[0033] Working principle: First, select a plugging ring 117 of different shapes according to the shape of the leakage gap. For example, a circular plugging ring 117 is selected for a circular gap. Then, insert the plugging block 111 with the plugging ring 117 into the slide groove 110. Then, put the outer hoop 101 on the outside of the pipeline. Then, loosen the first screw 107, put the first hoop ring 102 and the rotating hoop 104 on the outside of the outer hoop 101, align them with the position of the gap, and then clamp the first screw 107 into the clamping groove 108. Turn it tight through the first rotating wheel 109. In this way, the pipeline can be initially clamped. Then, the second screw 112 is tightened by the second rotating wheel 114, and the second screw 112 drives the abutment plate 113 to tighten the rotating hoop 104, so that the gap can be tightened at the upper end of the gap to strengthen the sealing, and at the same time, the sealing ring 117 can adapt to the shape of the gap to enhance the effect. After that, the second hoop ring 201 is put on both ends of the outer hoop tube 101, and the third rotating wheel 204 is rotated to tighten the second hoop ring 201, that is, to tighten the two ends of the outer hoop tube 101, so as to avoid the problem of leakage due to the fragility of a section of the pipeline around the gap.
