Description

Technical Field

[0001] The present application relates to the technical field of pipeline protection, and in particular to a chemical pipeline safety cover. Background Art

[0002] In chemical production, many chemical raw materials will produce toxic gases during preparation. For example, if ore contains sulfur, there will be sulfur-containing gas during the extraction process. Usually, sulfur-containing gas is toxic gas, and many toxic gases are easily soluble in water, so it is difficult to separate the toxic gas at the source. Only by transporting this part of the solution containing toxic gas through a pipeline, because the pipeline needs to be connected through multiple sections to form a complete transportation channel, it is easy to leak in the connection part. Once leaked, the toxic gas will accumulate around the connection part, which is easy to affect the health of the staff. Therefore, a chemical pipeline safety cover is needed to solve the above problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present application provides a chemical pipeline safety cover that performs safety protection operations on the connection between pipelines and flanges, thereby preventing workers from being directly exposed to the outside air after gas leakage and causing harm, thereby improving the practicality of the chemical pipeline safety cover.

[0005] (II) Technical solution

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a chemical pipeline safety cover, comprising a pipeline, wherein the middle region of the pipeline is fixedly connected by two flanges, the top of the flange is tightly fitted with a safety cover, and the two ends of the safety cover are tightly fitted with the outer side wall of the pipeline through a clamping mechanism;

[0007] The clamping mechanism includes a flexible material, which is fixedly connected to the inner wall of the safety cover. A sealing gasket is fixedly installed on the other end of the flexible material. An extension gasket is provided on the inner wall of the sealing gasket. A slide groove is fixedly installed on one end of the sealing gasket. The slide groove and the extension gasket are slidably mounted. Fixed grooves are provided around the top of the sealing gasket. A fixed pad is tightly fitted on the fixed groove, and the fixed pad is fixedly connected by a locking mechanism.

[0008] Preferably, the locking mechanism comprises two fixing plates, which are symmetrically fixedly mounted on the outer side wall of the fixing pad, wherein a screw is rotatably mounted on one of the fixing plates, and the screw is screwed to the other fixing plate.

[0009] Furthermore, a handle is fixedly mounted on the outer side wall of the screw.

[0010] Furthermore, an identification plate is attached to the outer side wall of the safety cover.

[0011] Based on the above solution, the inner wall of the sealing gasket is coated with anti-slip paint.

[0013] Compared with the prior art, the present application provides a chemical pipeline safety cover, which has the following beneficial effects:

[0014] The chemical pipeline safety cover performs sealing and protection operations on the connection between the pipeline and the flange by installing the safety cover, flexible materials and sealing gaskets. The extension pad on the sealing gasket is slidably mounted with the slide groove at the bottom of the sealing gasket, so that the device and the pipeline are closely fitted. The two fixing plates are clamped with the fixing gasket under the cooperation of the locking mechanism, so that the sealing gasket is stably fixed on the outer wall of the pipeline, thereby performing safety protection operations on the connection between the pipeline and the flange, thereby preventing direct exposure to the outside air after gas leakage to cause harm to workers, thereby improving practicality.

The extension pad 6 on the sealing gasket 5 is slidably clamped with the slide groove 7 at the bottom end of the sealing gasket 5, so that the device and the pipeline 1 are closely fitted. The two fixing plates 10 are clamped with the fixing gasket 9 under the cooperation of the locking mechanism, so that the sealing gasket 5 is stably fixed on the outer wall of the pipeline 1, and the connection between the pipeline 1 and the flange 2 is safely protected, so as to avoid direct exposure to the outside air after gas leakage to cause harm to workers, thereby improving practicality.
