Description

Technical Field

[0001] This utility model belongs to the field of chemical technology, and more specifically, it relates to a safety cover for chemical pipelines. Background Technology

[0002] Chemical pipelines are an indispensable and important component in chemical production, mainly used to transport various chemical products, including toxic, harmful, and corrosive media, in liquid, gaseous, and solid states.

[0003] Chemical pipelines are widely used. However, when the products transported inside these pipelines are corrosive, the sealing gaskets at the joints are prone to corrosion and damage after prolonged use. This can lead to leaks at the connection between two chemical pipelines, causing environmental pollution and even safety accidents. Therefore, accurate and timely testing of pipeline sealing is essential. While existing safety covers for chemical pipelines can prevent the spread of leaked gas to some extent, they still have some shortcomings. Some safety covers lack effective alarm functions and cannot promptly alert personnel when a leak occurs, resulting in long maintenance response times.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings to provide a safety cover for chemical pipelines, in order to achieve a more practical purpose. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a safety cover for chemical pipelines, which is achieved by the following specific technical means:

[0006] A safety cover for a chemical pipeline includes two pipeline bodies. The same side of the two pipeline bodies is fixedly installed by a plurality of first fixing bolts. A first protective cover and a second protective cover are respectively provided on the outer side of the two pipeline bodies. Fixing blocks are installed above and below the first and second protective covers, and second fixing bolts are threaded between the same set of fixing blocks. A mounting shell is installed on one side of the inner wall of the first and second protective covers. An inner cavity is opened inside the two mounting shells. An elastic plate is provided on the inner wall of the two inner cavities. A connecting rod is installed on one side of the two elastic plates, and an external connector is installed on the opposite side of the first and second protective covers.

[0007] Preferably, one end of each of the two connecting rods extends into the interior of the corresponding external connector, and a malleable plate is installed at one end of each of the two connecting rods. A connecting post is installed on one side of each of the two malleable plates, and a spring is sleeved on the outer side of each of the two connecting posts. One end of each of the two springs is fixed to the inner wall of the corresponding external connector. A touch switch is installed on one side of the inner wall of each of the two external connectors, and an alarm light and a buzzer are respectively installed on one side of each of the two external connectors.

[0008] Preferably, both sides of the inner walls of the two outer seats are provided with sliding grooves, and the two sides of the two plastic plates are respectively slidably connected to the inner walls of the corresponding sliding grooves.

[0009] Preferably, both ends of the two mounting housings are provided with air inlets communicating with the inner cavity, and one side of the two mounting housings is provided with multiple air inlets communicating with the inner cavity.

[0010] Preferably, both of the plastic sheets are made of natural rubber, which has a high modulus of elasticity and ductility.

[0011] Preferably, the two touch switches are electrically connected to the corresponding alarm light and buzzer via wires.

[0012] Preferably, sealing rings are installed on both sides of the first and second protective covers, and the inner sides of the plurality of sealing rings are respectively attached to the two pipe bodies.

[0013] Preferably, the inner walls of the first and second protective covers on the same side are both embedded with a sealing layer, and the sealing layer is made of nitrile rubber.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention features elastic plates on the inner walls of both sides of the mounting housing. In the event of a gas leak, the increased internal pressure causes the elastic plates to deform, pushing the connecting rod and moving a malleable plate along the inner wall of the slide. Ultimately, the malleable plate presses against a trigger switch. When pressed, the trigger switches send signals to an alarm light and a buzzer via wires, simultaneously issuing a warning. These two different warning methods facilitate timely detection and maintenance of the device. The invention also enhances the sealing performance on both sides with sealing rings to prevent leakage. Furthermore, a sealing layer made of nitrile rubber is embedded in the inner wall of both the first and second protective covers. Nitrile rubber has excellent oil resistance and elasticity; its elastic deformation fills the sealing gap when a gas leak occurs, further enhancing the sealing effect. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example:

[0025] As attached Figure 1 To be continued Figure 5 As shown:

[0026] This utility model provides a safety cover for a chemical pipeline, comprising two pipeline bodies 1. The two pipeline bodies 1 are fixedly installed on the same side by a plurality of first fixing bolts 2. A first protective cover 3 and a second protective cover 4 are respectively provided on the outer side of the two pipeline bodies 1. Fixing blocks 5 are installed above and below the first protective cover 3 and the second protective cover 4, and second fixing bolts 6 are threaded between the same set of fixing blocks 5. A mounting shell 7 is installed on one side of the inner wall of the first protective cover 3 and the second protective cover 4. An inner cavity 8 is opened inside the two mounting shells 7. An elastic plate 9 is provided on the inner wall of the two inner cavities 8. A connecting rod 12 is installed on one side of the two elastic plates 9, and an external connector 13 is installed on the opposite side of the first protective cover 3 and the second protective cover 4.

[0027] One end of each of the two connecting rods 12 extends into the interior of the corresponding external connector 13, and a malleable plate 15 is installed at one end of each of the two connecting rods 12. A connecting post 16 is installed on one side of each of the two malleable plates 15, and a spring 17 is sleeved on the outer side of each of the two connecting posts 16. One end of each spring 17 is fixed to the inner wall of the corresponding external connector 13. A touch switch 18 is installed on one side of the inner wall of each of the two external connectors 13, and an alarm light 19 and a buzzer 20 are respectively installed on one side of each of the two external connectors 13. The connection is achieved through the housing 7 installed on both sides. The inner wall is equipped with elastic plates 9. When gas leaks, the internal gas pressure changes and increases, causing the elastic plates 9 to deform. This pushes the connecting rod 12 to move the plastic plate 15 along the inner wall of the slide 14. Eventually, the plastic plate 15 squeezes and touches the trigger switch 18. When the trigger switches 18 on both sides are squeezed, they send signals to the alarm light 19 and the buzzer 20 through wires. The alarm light 19 and the buzzer 20 simultaneously issue a warning. These two different warning methods make it easier for staff to detect leaks in a timely manner and to maintain and handle leaks in the device.

[0028] The inner walls of the two outer seats 13 are provided with grooves 14 on both sides. The two sides of the two plastic plates 15 are slidably connected to the inner walls of the corresponding grooves 14. The plastic plates 15 deform when they are squeezed, which facilitates their sliding on the inner walls of the grooves 14. The function of the grooves 14 is to make the sliding of the plastic plates 15 smoother.

[0029] Both ends of the two mounting housings 7 are provided with air inlets 11 that communicate with the inner cavity 8, and one side of each of the two mounting housings 7 is provided with multiple air inlets 10 that communicate with the inner cavity 8. By providing air inlets 11 at both ends and air inlets 10 in the middle, gas can enter the inner cavity 8 immediately when a leak occurs, making the gas leak more timely.

[0030] Both of the plastic plates 15 are made of natural rubber, which has a high elastic modulus and extensibility. The plastic plates 15 made of natural rubber have a high elastic modulus and extensibility, and can withstand a large compressive force without breaking. They can quickly return to their original shape after the external force is removed.

[0031] The two touch switches 18 are electrically connected to the corresponding alarm light 19 and buzzer 20 via wires. When the touch switch 18 is squeezed, it sends a signal to the alarm light 19 and buzzer 20 via the wires.

[0032] The first protective cover 3 and the second protective cover 4 are equipped with sealing rings 21 on both sides, and the inner sides of the multiple sealing rings 21 are respectively attached to the two pipe bodies 1. The sealing of both sides is enhanced by the sealing rings 21 on both sides to prevent leakage.

[0033] The inner walls of the first protective cover 3 and the second protective cover 4 on the same side are both embedded with a sealing layer 22, and the sealing layer 22 is made of nitrile rubber. Nitrile rubber has good oil resistance and elasticity. When gas leakage occurs, its elastic deformation can fill the sealing gap, thereby further enhancing the sealing effect.

[0034] The working principle of this embodiment is as follows: First, when a gas leak occurs in the chemical pipeline, the leaked gas will enter the inner cavity 8 through the air inlets 11 at both ends of the housing 7 and the air inlet 10 in the middle. The elastic plate 9 in the inner cavity 8 will deform under the action of gas pressure. The deformation of the elastic plate 9 will push the connecting rod 12. The connecting rod 12 will drive the plastic plate 15 to move on the inner wall of the slide groove 14. The plastic plate 15 is made of natural rubber and has a high elastic modulus and extensibility. It can deform under the pressure and slide along the slide groove 14. During the sliding process, the plastic plate 15 will squeeze and touch the touch switch 18. After being squeezed, the touch switch 18 will send a signal to the alarm light 19 and the buzzer 20 through the wire. After receiving the signal, the alarm light 19 and the buzzer 20 will start at the same time and issue a warning through light and sound respectively to remind the staff that there is a leak in the pipeline, so as to facilitate timely detection and handling.

[0035] Secondly, sealing rings 21 are installed on both sides of the first protective cover 3 and the second protective cover 4, and the inner wall is embedded with a sealing layer 22 made of nitrile rubber. When gas leaks, the sealing rings 21 and the sealing layer 22 fill the sealing gap through elastic deformation, enhance the sealing effect, and prevent further gas leakage. The entire device achieves rapid detection and alarm of gas leaks through the coordinated action of components such as the elastic plate 9, the connecting rod 12, the plastic plate 15, and the touch switch 18. At the same time, the sealing performance is enhanced by the sealing rings 21 and the sealing layer 22 to ensure the safe operation of the chemical pipeline.

[0036] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
