Description

Technical Field

[0001] This invention relates to the field of chemical safety technology, and in particular to a gas leak detection device for chemical safety production. Background Technology

[0002] Chemical pipelines are essential equipment used in chemical production to transport various fluids (such as gases, liquids, and slurries), and are widely used in industries such as petroleum, chemicals, pharmaceuticals, and food. The design, material selection, installation, and maintenance of chemical pipelines are crucial to the safety and efficiency of production.

[0003] During material transport through pipelines, the impact of materials and the resulting deformation, as well as thermal expansion and contraction, can easily cause aging, damage, and failure of the sealing structure at the flanges, especially with highly corrosive materials. Existing protective measures mostly involve adding bellows and installing sensors around the pipeline to monitor for leaks. However, if a leak does occur, these measures lack the ability to prevent the material from spreading. Summary of the Invention

[0004] To address the aforementioned problems, this invention discloses a gas leak detection device for chemical safety production, comprising a first clamping component and a second clamping component, which are clamped together at a pipe flange. The first and second clamping components enclose the flange, creating a relatively independent space at the flange. If material leaks at the flange, the leaked material directly enters this space, providing a sealing and protective function. Simultaneously, even small leaks accumulate over time, increasing their internal concentration and facilitating sensor detection.

[0005] Both the first and second clamping components include arc-shaped parts, which are located within a semi-circular ring and are hollow on the inner side. A receiving groove is provided on the inner edge of the arc-shaped part, and a sealing ring is disposed inside the receiving groove. The sealing ring enhances the sealing performance between the first and second clamping components and the pipeline.

[0006] A sensor is provided on the outer sidewall of the second clamping component. The sensor includes a main body, and a probe is fixedly connected to the lower end of the main body. The sensor monitors for material leakage, and a monitoring unit is installed inside the probe.

[0007] Preferably, the end sidewall of the arc-shaped component is radially fixedly connected with a side lug, and the end sidewall of the arc-shaped component is axially fixedly connected with a side plate. A first bolt is inserted into both the side lug and the side plate. The first clamping component and the second clamping component are fixedly connected by the first bolt and the nut.

[0008] Preferably, a convex ring is fixedly connected to the side wall of the arc-shaped component, and the convex ring hugs the side wall of the pipe. An opening is provided between the convex ring and the side plate, and a clamp is fitted onto the outer side wall of the convex ring. The opening facilitates the clamp to be fitted onto the convex ring, while the clamp ensures that the convex ring can tightly hug the pipe.

[0009] Preferably, the clamping device comprises a steel coil with a connecting plate on it. A second bolt is threadedly connected to the middle of the connecting plate, and the end of the second bolt abuts against a convex ring. When the clamping device is fitted onto the first and second clamping parts, the steel coil is radially pulled by rotating the second bolt, thereby tightening the steel coil and firmly fixing the first and second clamping parts.

[0010] Preferably, the arc-shaped part belonging to the second clamping member has a mounting base on its side wall, and third bolts are inserted at the four corners of the main body, with the third bolts threaded into the pre-set threaded holes of the mounting base. The mounting base is provided to fix the sensor in place.

[0011] Preferably, the mounting base has a receiving cavity extending through the arc-shaped member at its center, and the probe is located inside the receiving cavity. The probe is placed inside the receiving cavity to monitor whether there is material leakage inside the first and second clamping members.

[0012] The beneficial effects of this invention are as follows:

[0013] 1. It is equipped with a first clamping part and a second clamping part to wrap around the flange. If a leak occurs at the flange, it can also prevent the spread.

[0014] 2. Equipped with sensors to monitor whether there is material leakage inside the first and second clamping parts.

[0015] 3. If a slight leak occurs at the flange, the first and second clamping parts are set up to confine the material inside, and the concentration of the material changes over time, which is conducive to the detection of the sensor. Attached Figure Description

When the clamp 2 is installed, the clamp 2 is pre-wound around the convex ring 6. Then the steel coil 23 and the connecting plate 22 are riveted together. Then the second bolt 21 is rotated to pull the steel coil 23 radially, that is, the steel coil 23 is tightened, and the first clamping member 1 and the second clamping member 4 are fixedly connected.

[0030] The side wall of the arc-shaped part 7 belonging to the second clamping part 4 is provided with a mounting base 13. The upper end face of the mounting base 13 is a cube.
