Description

Technical Field

[0001] This utility model relates to the field of inspection device technology, specifically to a pipeline safety valve inspection device. Background Technology

[0002] A safety valve is a special valve whose opening and closing element is normally closed under the action of external force. When the pressure of the medium in the equipment or pipeline rises above the specified value, it prevents the pressure of the medium in the pipeline or equipment from exceeding the specified value by discharging the medium to the outside of the system.

[0003] Existing pipeline safety valve inspection devices lack a real-time, efficient sealing detection mechanism, making it impossible to detect minute leaks at pipeline connections during the installation and commissioning of safety valves. Typically, sealing tests are only performed manually or using additional equipment after the entire inspection process is complete. This not only leads to low inspection efficiency but also risks media leakage, environmental pollution, and even safety accidents due to the failure to detect leaks in time. Furthermore, the fixed position or complex adjustment methods of existing inspection devices make it difficult to quickly and accurately adapt to safety valves of different sizes. This necessitates significant time and manpower for adjusting and calibrating pipeline positions when changing the inspection target, reducing the flexibility and efficiency of the inspection work, increasing equipment operating costs, and failing to meet diverse inspection needs.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A pipeline safety valve inspection device includes a base. An L-shaped support chamber is fixedly connected to one end cavity of the base via a lateral moving mechanism.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model discloses a pipeline safety valve inspection device.

[0026] This utility model provides, for example Figures 1-3 The pipeline safety valve inspection device shown includes a base 1. An L-shaped support chamber 2 is fixedly connected to one end cavity of the base 1 through a lateral moving mechanism. A first support chamber 3 is fixedly connected to the cavity of the L-shaped support chamber 2 through a vertical adjusting mechanism. A second connecting chamber 4 is fixedly connected to one top end of the base 1. Test connection pipeline devices 5 are fixedly connected to the side walls of both the first support chamber 3 and the second connecting chamber 4. A test power supply device 6 is fixedly connected to the other end cavity of the base 1.

[0027] The other end of the first support chamber 3 is fixedly connected to a discharge chamber 7. A one-way valve 8 is fixedly connected inside the cavity of the discharge chamber 7. A discharge interface pipe 9 is fixedly connected to the side wall of the discharge chamber 7. Both ends of the test connection pipeline device 5 include a sealing sleeve 10. A sealing inner tube 11 is rotatably connected inside the cavity of the sealing sleeve 10. One end of the sealing inner tube 11 passes through the sealing sleeve 10, and a connecting ring device 12 is fixedly connected to the tube wall. A gas detection sensor 13 and a liquid detection sensor 14 are fixedly connected to the top two ends of the connecting ring device 12, respectively. A display controller 15 is fixedly connected to the side wall of the base 1. By utilizing the coordinated operation of the set horizontal moving mechanism and the vertical adjustment mechanism, the spatial position of the first support chamber 3 can be flexibly adjusted. The test channel is constructed by the set first support chamber 3 and the second connection chamber 4 through the test connection pipeline device 5. The set test power supply device 6 provides power for the test process. The power source and media supply, along with the overall structural design, enable flexible adjustment and functional integration of the safety valve detection position, improving detection adaptability. The discharge chamber 7, in conjunction with the one-way valve 8 and discharge interface pipe 9, achieves unidirectional safe discharge of the media after testing. The sealing sleeve 10 and the sealing inner tube 11 form a sealed connection structure, ensuring airtightness during the testing process. The connecting ring device 12 integrates a gas detection sensor 13 and a liquid detection sensor 14, enabling real-time monitoring of the sealing status at the connection. The display controller 15 provides real-time feedback of detection data, achieving visualized monitoring and intelligent control of leakage. This solves the problem of traditional devices being unable to detect sealing in real time, thus addressing the inconvenience of existing pipeline safety valve inspection devices in timely detecting the sealing of pipeline connections and the difficulty in adjusting the test pipeline position according to the safety valve size.

[0028] In order to move the first support chamber 3 laterally, such as Figure 1 and 2As shown, the lateral movement mechanism includes an electric push rod 16, a first sliding opening 17, and a limiting slider 18. The electric push rod 16 is fixedly connected to one end cavity of the base 1. The first sliding opening 17 is opened at one top end of the base 1, and the limiting slider 18 is slidably connected thereto. The side wall of the limiting slider 18 is fixedly connected to one end of the electric push rod 16, and the top of the limiting slider 18 is fixedly connected to the bottom of the L-shaped support chamber 2. The electric push rod 16 drives the limiting slider 18 to slide along the first sliding opening 17, thereby causing the L-shaped support chamber 2 to achieve lateral displacement. The limiting slider 18 ensures stable guidance during the movement process and avoids deviation. The lateral position adjustment is achieved through electric control, and the position of the first support chamber 3 can be flexibly adjusted according to the horizontal installation size of the safety valve and the requirements, improving the versatility of the device.

[0029] In order to drive the first support chamber 3 to move vertically, such as Figures 1-3 As shown, the vertical adjustment mechanism includes a hydraulic rod 19, a second sliding port 20, and a sliding support arm 21. The hydraulic rod 19 is fixedly connected inside the cavity of the L-shaped support chamber 2. The second sliding port 20 is opened on the side wall of the L-shaped support chamber 2, and the sliding support arm 21 is slidably connected thereto. The bottom of the sliding support arm 21 is fixedly connected to one end of the hydraulic rod 19, and the side wall of the sliding support arm 21 is fixedly connected to the side wall of the first support chamber 3. By using the extension and retraction action of the hydraulic rod 19, the sliding support arm 21 is pushed to move vertically along the second sliding port 20, thereby driving the first support chamber 3 to achieve vertical height adjustment. The hydraulic drive provides stable support force, ensuring a smooth adjustment process. It can be quickly positioned according to the vertical installation height requirements of the safety valve, solving the problem of the non-adjustable height of the test pipeline in traditional devices and improving testing efficiency.

[0030] To facilitate the connection between the power supply device 6 and the second connecting chamber 4 for providing test fluid, such as... Figure 1 and 2 As shown, the output end of the test power supply device 6 is fixedly connected to an output hose 22, and the other end of the output hose 22 is fixedly connected to a threaded connecting sleeve 23. The input end of the second connecting chamber 4 is fixedly connected to a threaded input end 24. The threaded connecting sleeve 23 and the threaded input end 24 are threadedly connected. The output hose 22 provides a flexible connection to adapt to changes in position between the test power supply device 6 and the second connecting chamber 4. The threaded connection between the threaded connecting sleeve 23 and the threaded input end 24 enables quick assembly and disassembly, facilitating equipment maintenance and media pipeline replacement. This ensures stable transmission of the test medium to the detection channel and enhances the flexibility and reliability of the device connection.

[0031] To provide the sensor with a certain response time and facilitate connection with the safety valve, such as Figure 1 and 2As shown, the connecting ring device 12 includes a bucket-shaped support ring 25. The inner side wall surface of the bucket-shaped support ring 25 is provided with multiple mounting holes 26. The bucket-shaped support ring 25 provides a mounting carrier for the gas detection sensor 13, the liquid detection sensor 14 and other accessories. The bucket shape helps to slow down the gas flow rate and accumulate liquid, providing the sensor with a certain reaction time. The multiple mounting holes 26 facilitate connection with the flange in the safety valve.

[0032] To facilitate relocation and extend the service life of the test connection pipe assembly 5, such as Figure 1 and 2 As shown, the bottom of the base 1 is fixedly connected with multiple casters 27, and the inner walls of the test connection pipe devices 5 at both ends are provided with anti-corrosion ceramic coating. The casters 27 enable the device to move flexibly, making it easy to deploy quickly in different testing sites. The anti-corrosion ceramic coating can effectively resist the chemical corrosion of the test medium, extend the service life of the test connection pipe device 5, reduce the risk of leakage caused by corrosion, reduce equipment maintenance costs, and improve the overall reliability of the device.
