It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

The utility model provides a gas pipeline protection device, comprising a gas pipeline 1, flanges 101 are installed at both ends of the gas pipeline 1, an inner protective shell 2 is installed on the outer wall of the gas pipeline 1, an outer protective shell 3 is installed on the outer side of the inner protective shell 2, the inner protective shell 2 and the outer protective shell 3 are connected by a connecting plate 4, the inner protective shell 2 is composed of a left shell 201 and a right shell 202, a convex block 203 is symmetrically fixedly connected to the left shell 201, the convex block 203 and the right shell 202 are mutually engaged, the left shell 201 and the right shell 202 are both annular, a claw 204 is fixedly connected between the inner walls of the left shell 201 and the right shell 202, and the inner protective shell 2 can be stably fixed on the outer wall of the gas pipeline 1 as a whole through the structural arrangement of multiple groups of claws 204.

When the gas pipeline 1 protection device is actually used, the inner protective shell 2 is first installed on the outer side of the gas pipeline 1, and the left shell 201 and the right shell 202 in the inner protective shell 2 are successively installed on the outer wall of the gas pipeline 1. Since the inner walls of the left shell 201 and the right shell 202 are both installed with claws 204, and the left shell 201 is installed with a protrusion 203, the protrusion 203 and the right shell 202 are mutually embedded, so that the left shell 201 and the right shell 202 are mutually embedded and cooperated to form a complete ring body. Since the outer protective shell 3 and the inner protective shell 2 are connected through the connecting plate 4, the outer protective shell 3 and the inner protective shell 2 are installed simultaneously during the actual installation process. When the left block 301 and the right block 302 in the outer protective shell 3 abut against each other, the staff manually installs the bolts 304 to the two The left block 301 and the right block 302 on the side make the left block 301 and the right block 302 in the outer protective shell 3 connected as a whole. Since the two ends of the outer protective shell 3 are fixedly connected with the sealing ring 5, the sealing performance of the abutment position between the gas pipeline 1 and the outer protective shell 3 is good. By sequentially arranging double-layer protective shells on the outer wall of the gas pipeline 1, external dust and water vapor will not immediately react with the gas pipeline 1 for oxidation, thereby reducing the corrosion efficiency of the gas pipeline 1 and extending the service life of the gas pipeline 1. Compared with the conventional gas pipeline 1 directly exposed to the air, the service life of the gas pipeline 1 is greatly extended, and a large amount of dust will not accumulate on the surface of the gas pipeline 1, thereby maintaining the working environment around the gas pipeline 1.

Since claws are installed on the inner walls of the left shell and the right shell, and a protrusion is installed on the left shell, the protrusion and the right shell are embedded in each other, so that the left shell and the right shell are embedded in each other to form a whole ring body. Since the outer protective shell and the inner protective shell are connected by a connecting plate, the outer protective shell and the inner protective shell are installed simultaneously during the actual installation process. When the left block and the right block in the outer protective shell abut against each other, the staff manually installs the bolts into the left block and the right block on both sides, so that the left block and the right block in the outer protective shell are connected into a whole. Since the two ends of the outer protective shell are fixedly connected with sealing rings, the sealing of the abutting position between the gas pipeline and the outer protective shell is good.

To sum up, the utility model arranges double-layer protective shells on the outer wall of the gas pipeline in sequence, so that external dust and water vapor will not immediately react with the gas pipeline for oxidation, thereby reducing the corrosion efficiency of the gas pipeline and extending the service life of the gas pipeline. Compared with the conventional gas pipeline directly exposed to the air, the service life of the gas pipeline is greatly extended, a large amount of dust will not accumulate on the surface of the gas pipeline, and the working environment around the gas pipeline is maintained. The overall structure of the utility model is compact, the spatial layout is reasonable, and it is easy for the staff to install and maintain. By installing a limit plate on the outer protective shell, the limit plates on both sides are finally connected by bolts to complete the installation and fixing of the outer protective shell. The structural setting of the sealing ring ensures good air tightness at the abutting position.
