Description

Technical Field

[0001] This utility model relates to the field of chemical pipeline technology, specifically a safety cover for leak-proof chemical pipelines. Background Technology

[0002] Chemical pipelines are mainly used in industries such as chemical, dye, pharmaceutical, pesticide, metallurgy, machinery, power, electronics, and environmental protection to transport corrosive media. Leakage can sometimes occur at the joints of chemical pipelines, such as flange connections and valves, necessitating the installation of safety covers around the pipelines.

[0003] Because existing leak-proof safety covers for chemical pipelines can cause gas leaks when they occur at pipeline connections, these leaks can enter the safety cover without being detected in time, potentially leading to safety hazards. Furthermore, chemical pipeline safety covers are generally composed of two parts that are fixed together by multiple screws, making the installation process cumbersome, time-consuming, and labor-intensive, and inconvenient for later disassembly and maintenance.

[0004] Therefore, we propose a safety cover for leak-proof chemical pipelines. Utility Model Content

[0005] The purpose of this invention is to provide a safety cover for leak-proof chemical pipelines to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a safety cover for leak-proof chemical pipelines, comprising a front protective cover, a rear protective cover, and a top cover. The bottom and top sides of the front protective cover are fixedly connected to fixing slots. The bottom and top sides of the rear protective cover are rotatably connected to threaded rods. A fixing knob is threaded through the threaded rod and is in tight contact with the fixing slot. Arc-shaped slots are integrally connected to both sides of the front and rear protective covers. A sealing ring is provided inside the arc-shaped slot. A snap-fit ​​sliding groove is provided on the top of both sides inside the front and rear protective covers. A connecting foot is fixedly installed at the bottom of the inside of the top cover. A snap-fit ​​post is fixedly installed at the bottom of the connecting foot. The snap-fit ​​post slides and snaps into the inside of the snap-fit ​​sliding groove. An installation groove is provided at the bottom of the front and rear protective covers. A fixing through groove is integrally provided on the top of the installation groove. A sensor is fixedly installed inside the fixing through groove.

[0007] Optionally, an observation window is provided in the middle of the top of the top cover, and a rubber ring is provided on the contact surface between the bottom of the top cover and the protective cover.

[0008] Optionally, the threaded rod engages with the inside of the fixing slot, and the fixing knob abuts against the side of the fixing slot away from the rear protective cover.

[0009] Optionally, the top of the mounting groove is provided with several evenly distributed fixing slots, which are connected to the interior of the front and rear protective covers, and the sensor is sealed and fixedly installed inside the fixing slots.

[0010] Optionally, the snap-fit ​​groove is inclined, and the snap-fit ​​grooves of the front protective cover and the rear protective cover are symmetrically arranged, and the diameter of the snap-fit ​​post is the same as the width of the snap-fit ​​groove.

[0011] Optionally, the front and rear protective covers are symmetrically arranged with arc-shaped slots that are integrally connected, and the diameter of the inner arc surface of the arc-shaped slot is the same as the diameter of the pipe.

[0012] Optionally, the front and rear protective covers are symmetrically arranged on both sides of the pipe connection, the length of the threaded rod is greater than the sum of the thicknesses of the front and rear protective covers, and a sealing rubber gasket is provided at the connection between the front and rear protective covers.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This leak-proof chemical pipeline safety cover, by setting a fixing groove and a threaded rod, symmetrically sets the front and rear protective covers on the front and rear sides of the pipeline connection. Then, rotate the threaded rod to engage with the inside of the fixing groove, and rotate the fixing knob to make the fixing knob and the fixing groove come into tight contact, thereby pushing the front and rear protective covers to abut together. At the same time, as the protective covers and the rear protective covers come closer and abut together, the locking column moves downward inside the locking slide groove, fixing the top cover to the top of the protective covers and the rear protective cover. The operation is simple and convenient, saving time and effort.

[0015] 2. This leak-proof chemical pipeline safety cover has an installation groove and multiple fixed through grooves for installing the necessary sensors, so that the sensors are connected to the inside of the protective cover. When a leak occurs at the pipeline connection, the leaked chemical raw material can be detected immediately by the sensor, and an alarm will be issued. At the same time, the observation window set in the middle of the top cover can be used to observe the pipeline connection. Attached Figure Description

At the same time, the observation window 14 set in the middle of the top cover 3 can be used to observe the pipe connection.

[0024] Working principle:

[0025] The front protective cover 1 and the rear protective cover 2 are symmetrically arranged on the front and rear sides of the pipe connection. Then, the threaded rod 7 is rotated to engage with the inside of the fixing slot 8. The fixing knob 9 is rotated to make the fixing knob 9 and the fixing slot 8 come into tight contact, thereby pushing the front protective cover 1 and the rear protective cover 2 to abut together. At the same time, as the protective cover and the rear protective cover 2 come closer and abut together, the locking post 11 moves downward inside the locking slide groove 12, fixing the top cover 3 on the top of the protective cover and the rear protective cover 2. The operation is simple and convenient, saving time and effort. The required sensors 5 are installed through multiple fixing slots 13, so that the sensors 5 are connected to the inside of the protective cover.
