Description

Impact-resistant elbow Technical Field The utility model relates to the technical field of elbows, in particular to an impact-resistant elbow. Background In a pipeline system, the elbow is a pipe fitting for changing the pipeline direction, is a connecting pipe fitting commonly used in pipeline installation, and is widely used in basic engineering such as chemical industry, building, water supply, water drainage, petroleum, light and heavy industry, refrigeration, sanitation, water heating, fire protection, electric power, aerospace, shipbuilding and the like because the elbow pipe fitting has good comprehensive performance. The novel trinity anti-impact wear-resistant elbow that prior art publication No. CN 216743365U, the device improves the shock resistance of elbow through compound type material preparation elbow, but along with long-term use, the elbow can be impaired under the impact and the corruption of conveying medium, and can directly strike the elbow in the medium conveying process, lead to the elbow to produce vibration and take off, and in the liquid conveying process, tiny particle impurity in the liquid strikes the elbow inner wall under the drive of rivers and can cause serious wearing and tearing to the elbow inner wall, reduces the life of elbow. Disclosure of utility model The utility model aims to overcome the defect that the elbow is worn out by direct impact of liquid and particle impurities in the prior art, and provides an impact-resistant elbow. The shock-resistant elbow comprises a bent pipe body, flanges are fixedly connected to two ends of the pipe body, a buffer plate is arranged in the pipe body, the buffer plate is in an arc plate shape with a semicircular arc section, a plurality of blocking plates are arranged on the inner side of the buffer plate and are integrally connected with each other, the buffer plate and the blocking plates are elastic rubber plates, an opening is formed in the pipe body and is located on one outer diameter side, a cover plate is arranged at the opening, the cover plate is in an arc shape with a semicircular section and is fixed to the opening of the pipe body through bolts, the buffer plate is fixedly connected to the inner side of the cover plate, and filters are arranged in the pipe body and close to the two ports.
