Shock-resistant pipeline connecting structure

Abstract

The invention belongs to the technical field of pipeline connection, and provides a pipeline anti-seismic connection structure, which is installed at the junction of two transmission pipelines, including a connection pipeline, an anti-seismic clamp, a sealing ring and a connecting rod; the connection end of the transmission pipeline is inserted into the connection pipeline The anti-seismic clamps include two corresponding half clamps, the half clamps are semi-circular structures with different inner diameters on both sides, and the two half clamps are fitted on the conveying pipeline and connected by sealing rings. In the connection part of the pipeline, both ends of the half hoop body are provided with ear seats, and bolt holes for locking bolts are opened on the ear seats, and the two half hoop bodies are connected and fastened by the locking bolts and the first nut; the connecting rod There are at least two connecting rods, and the two ends of the connecting rod are detachably fixedly connected to the conveying pipe and the connecting pipe respectively through the connecting mechanism. The invention can make the pipeline connection maintain good connection sealing performance under the influence of earthquake and other external stresses, and improve the anti-seismic sealing performance of the pipeline connection.

Description

technical field [0001] The invention relates to the technical field of pipeline connection, in particular to a pipeline anti-seismic connection structure. Background technique [0002] Earthquakes will distort, wrinkle and break pipelines transporting oil and gas, make buried pipelines protrude from the ground, damage and collapse pipeline equipment and buildings, and cause great harm to the environment and residents in disaster-stricken areas; therefore, pipelines Anti-seismic becomes very important. Putting forward special deformation requirements on the key parts of the pipeline connection is an effective solution to realize the anti-seismic connection of pipelines. [0003] The pipe connections in the prior art are mostly realized by clamps, which are a connecting device for connecting grooved pipe fittings, valves and pipeline fittings. The joint has gaskets, rubber, silicone and PTFE. Due to its good performance, high sealing degree and easy installation, the clamp co...

Problems solved by technology

[0003] The pipe connections in the prior art are mostly realized by clamps, which are a connecting device for connecting grooved pipe fittings, valves and pipeline fittings. The joint has gaskets, rubber, silicone and PTFE. Due to its good performance, high sealing degree and easy installation, the clamp connection technology has become the first technology for liquid and gas pipeline connections, and has gradually replaced flange connections. Traditional pipeline connection methods such as welding and welding are not only more mature in technology, but also more widely used in the market. However, the structure of rigid connection of pipelines through clamps in the prior art can realize the sealed connection of two separate pipelines, but the connection Under the action of external stress such as earthquakes, different degrees of distortion and deformation will occur, or even break, which will affect the sealing between the two separated pipes and cause the leakage of transported liquid or gas, which will not only affect the continued work and use, It will also cause a large environmental pollution problem and cannot meet the use requirements of the anti-seismic function of the pipeline connection
