A high-voltage swivel elbow structure that is easy to disassemble

Abstract

The invention discloses a high-pressure swivel elbow structure that is easy to assemble and disassemble. It includes an elbow, the two ends of the elbow are symmetrically provided with connectors, the connectors are inserted into the connectors, and the outside of the connectors is provided with a protective groove. , a protective ring is rotated on the protective groove, and a number of clamping holes are opened in a circular array on the connector, and the clamping holes are located at the bottom of the protective groove; A number of clamping slots, a clamping block is arranged in the clamping slot, and the connector is installed in the clamping hole on the connector at one end of the elbow through the clamping block, that is, two movable elbows can pass through one connector Carry out snap connection, when it is necessary to dismantle and separate the two swivel elbows, just press the snap-in block on the plug-in block in the snap-in hole to remove and separate the swivel elbow, which is convenient and quick to install and easy to dismantle.

Description

technical field [0001] The invention relates to the technical field of high-pressure swivel elbows, in particular to a structure of a high-pressure swivel elbow that is easy to assemble and disassemble. Background technique [0002] With the gradual expansion of fracturing construction scale, the fracturing construction of cluster wells is gradually increasing, and in the process of zipper fracturing operation of cluster wells, due to the limitation of the operation well site and the requirements of construction scale, it is necessary to use multiple 3-inch Or 4-inch fracturing pipelines are connected in parallel to meet the requirements of on-site operations. The demand for high-pressure manifolds is large, the connection is complicated, and the floor area is large. The complicated pipeline layout slows down the construction period and brings more pipeline thorns. leakage risk; [0003] Therefore, it is necessary to develop a single-channel high-pressure pipeline with a la...

[0002] With the gradual expansion of fracturing construction scale, the fracturing construction of cluster wells is gradually increasing, and in the process of zipper fracturing operation of cluster wells, due to the limitation of the operation well site and the requirements of construction scale, it is necessary to use multiple 3-inch Or 4-inch fracturing pipelines are connected in parallel to meet the requirements of on-site operations. The demand for high-pressure manifolds is large, the connection is complicated, and the floor area is large. The complicated pipeline layout slows down the construction period and brings more pipeline thorns. leakage risk;

[0003] Therefore, it is necessary to develop a single-channel high-pressure pipeline with a large diameter of more than 5 inches to simplify the pipeline connection on the job site and complete the large-scale fracturing construction of cluster wells quickly and efficiently. Restricted, volume requirements are limited, and the structure of using rolling elements to realize the rotation function is no longer applicable. The large-diameter high-pressure swivel elbow is the core component of the large-diameter single-channel high-pressure pipeline, and it is difficult to develop. The inner diameter of the steel ball swivel swivel elbow It can only be 4 inches. As the inner diameter increases, the number of steel balls is large, which is not conducive to installation and disassembly. When the swivel elbow is subjected to high pressure, the steel balls are easily damaged by shearing without any buffer protection under high pressure. , 4 inches or more steel ball type swivel swivel joint, the rotation friction resistance is large, the rotation is difficult, and the installation and construction are difficult;
