Detailed Implementation

[0018] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0019] A pipeline explosion-proof pressure testing device, such as Figures 1-4As shown, the device includes an explosion-proof frame 1 with a transparent top. Two symmetrical air inlet valves 2 are located on the top of the frame 1. An air outlet valve 3 is located on the right side of the frame 1. An oil filling cap 4 is snapped onto the front of the frame 1, with an oil filling port in the center. A pressure relief assembly 5 is located at the rear of the frame 1, consisting of a mounting component and a pressure relief valve. A sealing ring 6 is connected to the rear of the oil filling cap 4. Contact elements 7 are slidably connected to both sides of the frame 1, and these contact elements 7 are all through-connected to the frame 1. The inner sides of the contact elements 7 are arc-shaped, allowing them to contact the pipe sidewall. The contact element 7 is fitted with two limiting rods 8, which are slidably connected to the explosion-proof frame 1. Each limiting rod 8 has a limiting block on its outer end. Each contact element 7 is connected to the explosion-proof frame 1 with a spring 9, which is sleeved on the corresponding contact element 7. Each of the front and rear sides of the explosion-proof frame 1 is connected with a baffle 10. Each of the front and rear sides of the explosion-proof frame 1 is provided with a collection tank 11 for collecting oil. Each collection tank 11 is slidably provided with an oil suction element 12, which is slidably connected to the explosion-proof frame 1. The connection between the oil suction element 12 and the explosion-proof frame 1 is a detachable connection structure.

[0020] It should be noted that this device can be used for pipeline explosion-proof testing. First, remove the oil filler cap 4 and insert the pipeline into the explosion-proof frame 1. Then, replace the oil filler cap 4 and inject oil into the explosion-proof frame 1 through the oil filler cap 4 to increase the pressure. When the pipeline pressure threshold is reached, observe the pipeline condition. If the pipeline does not burst at this time, the ambient temperature can be changed by using the air inlet valve 2 to simulate the pipeline's withstand capacity under different ambient temperatures. At the same time, the contact element 7 can be pulled to compress the spring 9, and then the contact element 7 can be released to impact the pipeline. The test simulates the impact under high pressure to comprehensively test the explosion-proof capability of the pipeline. If the pipeline bursts, the oil inside will enter the explosion-proof frame 1 and be guided and limited by the baffle 10, allowing the oil to flow into the collection tank 11 and finally be absorbed and recovered by the oil suction component 12. Then, the oil suction component 12 can be extracted to process the absorbed and recovered oil to avoid waste. If the pipeline passes the test, the internal gas is discharged through the vent valve 3, and the pressure relief component 5 is activated to balance the internal pressure of the explosion-proof frame 1 with the external pressure. Finally, the oil filling cap 4 is removed and the pipeline is taken out.

[0021] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
