Description

Technical Field

[0001] The utility model relates to the technical field of pipeline pressure relief and discharge, in particular to an automatic pipeline overpressure relief device. Background Art

[0002] The relief device generally uses a safety pressure relief device to discharge the medium in the pipeline in time, so that the pressure of the medium in the pipeline drops rapidly.

[0003] Authorization announcement number CN212840059U discloses a pressure relief device for pipeline pressure discharge. The patented technology uses the medium in the pressure relief pipe to be initially depressurized by the elbow joint. After the initial depressurization, the medium is discharged from the output end of the elbow joint and directly contacts the water flow baffle to be further blocked by the water flow baffle. The blocked medium is guided out from each diversion port into the water flow guide member. The medium entering the water flow guide member directly contacts multiple inclined guide plates to further block and guide the high-speed guided medium. The medium finally exits the water flow. The trumpet-shaped port of the outlet part discharges into the drain trough. After multiple obstructions and diversions, the medium in the pressure relief pipe has no water leakage or splashing problems. However, in this solution, when the pipeline is pressure-relieved and discharged, the method of using elbow joints to reduce the pressure is not advisable. If the water pressure is too high, the elbow will cause the water flow to be blocked, which is not convenient for strong discharge. In addition, multiple guide plates will not only hinder the discharge, but also cause the water to flow through multiple paths, which will cause the water to be polluted, which is not good for health. Therefore, a pipeline overpressure automatic discharge device is needed to improve the above problems. Utility Model Content
