DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0032] REFERENCE Figures 1 to 3 An embodiment provided by the utility model: a high-temperature and high-pressure environment simulation device for safety valve detection, comprising a safety valve check table 1, the safety valve check table 1 is the basis of the whole device, and is used for checking the safety valve. It provides a stable working platform, carries other components, ensures that the whole detection process can be carried out at a fixed position, provides necessary support and working space for the detection of the safety valve, and the top front side of the safety valve check table 1 is fixedly connected with an electric guide rail 2. The electric guide rail 2 is installed at the top front side of the safety valve check table 1 and provides an accurate straight-line motion path for the connecting plate 3. Its role is that the position of the connecting plate 3 can be flexibly adjusted according to the detection needs, so that the subsequent square box 5 and other components are moved to the appropriate position, so that the safety valve is better detected and operated. The connecting plate 3 is slidably connected to the outside of the electric guide rail 2, the front side of the connecting plate 3 is rotatably connected with a rotating plate 4, and the connecting plate 3 serves as an intermediate component connecting the electric guide rail 2 and the rotating plate 4, and plays a role in transmitting motion and supporting. On the one hand, it slides on the electric guide rail 2 to realize position adjustment; on the other hand, it provides a mounting base for the rotating plate 4, so that the rotating plate 4 can be stably connected to the whole device, and subsequent operations are facilitated. The bottom of the rotating plate 4 is fixedly connected with the square box 5, and the rotating plate 4 is connected with the square box 5 at the bottom and can rotate. Such a design enables the square box 5 to adjust the angle and adapt to different detection needs, increasing the flexibility of the device. The position of the square box 5 can be adjusted through the rotating plate 4 according to the installation position of the safety valve and the detection angle requirement, so that the detection work is better carried out. The square box 5 is an important component in the device and can be used to install specific detection equipment or tools. It provides a closed space for these equipment, protects the equipment from the influence of the external environment, and also makes the installation and use of the equipment more orderly and standardized, ensuring the smooth progress of the detection work.

[0033] A dust collection pipe 6 is fixedly connected to the left side of the square box 5, and a funnel 8 is fixedly connected to the other end of the dust collection pipe 6. A dust collection box 7 is fixedly connected to the top of the safety valve calibration platform 1. The dust collection box 7 is used to collect and process dust and other impurities generated during the testing process. The internal filter screen 9 can effectively filter dust in the air. The suction fan 10 generates suction to draw dust-containing air into the dust collection box 7 through the dust collection pipe 6. After being filtered by the filter screen 9, clean air is discharged, ensuring the cleanliness of the testing environment. The filter screen 9 is fixedly connected inside the dust collection box 7 and is a key component for dust removal. It intercepts dust and other impurities in the air through physical blocking, allowing only clean air to pass through. The fine structure of the filter screen 9 can effectively filter out dust particles of different sizes, improving the dust removal effect. A suction fan 10 is fixedly connected to the right inner wall of the dust collection box 7 and provides power for the dust removal process. It generates a powerful suction force, drawing dust-laden air from the detection area into the dust collection pipe 6, and then into the dust collection box 7 for filtration. The power of the suction fan 10 determines the efficiency and speed of dust removal. A multi-stage telescopic rod 11 is rotatably connected to the front of the connecting plate 3, connecting the connecting plate 3 and the rotating plate 4, and is used to adjust the angle of the rotating plate 4. By extending and retracting the multi-stage telescopic rod 11, the tilt angle of the rotating plate 4 can be changed, thereby adjusting the position and angle of the square box 5 to meet different detection needs, increasing the flexibility and operability of the device. A cooling component for cooling the safety valve calibration table 1 is fixedly connected to the rear of the safety valve calibration table 1.

[0034] Reference Figure 2 , Figure 4The cooling assembly comprises a fixed box 12, which is a shell of the cooling assembly and provides installation and protection space for the internal components. It is connected to the rear side of the safety valve calibration platform 1, integrates the cooling assembly with the calibration platform, and facilitates overall installation and use. At the same time, the fixed box 12 also plays a certain heat insulation and protection role. The front side of the fixed box 12 is fixedly connected to the rear side of the safety valve calibration platform 1, and the rear portion of the fixed box 12 is fixedly connected with filter covers 13 on the upper and lower sides. The filter covers 13 installed on the upper and lower sides of the rear portion of the fixed box 12 are used to filter the air entering the cooling assembly. When the fan 14 is working, the filter cover 13 can prevent dust, debris and the like from entering the inside of the fixed box 12, protecting the internal components such as the fan 14 and the water pump 15 from being damaged, and also ensuring the cleanliness of the cooling air. The inside of the fixed box 12 is fixedly connected with the fan 14 on the upper and lower sides. The fans 14 on the upper and lower sides of the inside of the fixed box 12 provide power for the air flow in the cooling process. They suck the external cold air into the fixed box 12, exchange heat through components such as the heat dissipation pipe 18, and then discharge the hot air, achieving the cooling of the safety valve calibration platform 1. The speed and air volume of the fan 14 can be adjusted as needed.

[0035] The bottom inner wall of the fixed box 12 is fixedly connected with the water pump 15, which is an important component in the cooling device. It draws the cooling liquid (such as water) from the water tank 17 and delivers it to the heat dissipation pipe 18 through the connecting pipe 16. The cooling liquid flows in the heat dissipation pipe 18, absorbs the heat generated by the safety valve calibration platform 1, and then returns to the water tank 17 for cooling, thus circulating back and forth to achieve continuous cooling of the calibration platform. The output end of the water pump 15 is fixedly connected with the connecting pipe 16, which connects the output end of the water pump 15 and the heat dissipation pipe 18, and plays a role in delivering the cooling liquid. It accurately delivers the cooling liquid drawn out by the water pump 15 to the heat dissipation pipe 18, ensuring that the cooling liquid can circulate normally in the cooling device to achieve effective cooling. The input end of the water pump 15 is fixedly connected with the heat dissipation pipe 18, which is fixed to the front inner wall and the bottom inner wall of the fixed box 12, and is a place for the cooling liquid to exchange heat with air. The cooling liquid flows in the heat dissipation pipe 18, exchanges heat with the external air through the pipe wall of the heat dissipation pipe 18, and releases heat, thereby reducing the temperature of the cooling liquid. The surface area and material of the heat dissipation pipe 18 will affect the efficiency of heat exchange. The left side of the connecting pipe 16 is fixedly connected with the water tank 17.

[0036] Referring to Figures 2 to 4The bottom of the water tank 17 is fixedly connected to the inner wall of the bottom of the fixed box 12, the left side of the water tank 17 is fixedly connected to the other end of the heat dissipation pipe 18, the front side of the heat dissipation pipe 18 is fixedly connected to the inner wall of the front side of the fixed box 12, the bottom of the dust removal box 7 is fixedly connected to the top of the fixed box 12, the outer part of the dust removal pipe 6 is fixedly connected to the left inner part of the dust removal box 7, the left side of the hopper 8 is fixedly connected to the inner wall of the left side of the dust removal box 7, the right side of the hopper 8 is fixedly connected to the left side of the filter screen 9, the front side of the connecting plate 3 is rotatably connected with the multi-stage telescopic rod 11, the other end of the multi-stage telescopic rod 11 is rotatably connected to the top front side of the rotating plate 4, the rear side of the connecting plate 3 is slidably connected to the top front side of the safety valve calibration platform 1, a plurality of heat dissipation holes 19 are formed in the right side of the fixed box 12, and the heat dissipation holes 19 formed in the right side of the fixed box 12 are used for discharging hot air generated in the cooling process. When the fan 14 sucks the external cold air into the fixed box 12 for heat exchange, the hot air needs to be discharged from the fixed box 12 through the heat dissipation holes 19 to maintain the normal operation of the cooling device. The number and size of the heat dissipation holes 19 will affect the discharge speed of the hot air.

[0037] Working principle: when it is needed to remove dust from the safety valve calibration platform 1, the multi-stage telescopic rod 11 is started to drive the rotating plate 4 to rotate to be flush with the ground, the electric guide rail 2 is started to move, and then the air suction fan 10 is started to drive the square box 5 to absorb dust on the safety valve calibration platform 1, the dust enters the hopper 8 through the action of the dust removal pipe 6, and under the action of the filter screen 9, the dust is collected into the dust removal box 7 and cannot float into the air, thereby achieving the dust removal of the platform of the calibration platform, and ensuring that the safety valve can normally work in the equipment operation process and preventing safety accidents caused by invalid safety valves.

[0038] When it is needed to dissipate heat from the safety valve calibration platform 1, the water pump 15 is started to drive the cooling water in the water tank 17 to enter the water pump 15 through the connecting pipe 16, the cooling water in the water pump 15 enters the water tank 17 through the heat dissipation pipe 18 to form a closed loop, and then the fan 14 is started to dissipate heat from the heat dissipation pipe 18 and the safety valve calibration platform under the action of the fan 14, thereby reducing the working temperature of the equipment, slowing down the aging and damage speed of the components, and prolonging the service life of the equipment.
