Description

A high-temperature deformation detection device for pipes Technical Field

[0001] This utility model relates to the field of pipe performance testing technology, specifically a high-temperature deformation detection device for pipes. Background Technology

[0002] In the production process of pipes, high temperature resistance testing is a routine test to measure one of the pipe's performance characteristics. For example, the environmentally friendly plastic high temperature deformation testing device for pipes disclosed in Chinese authorized patent CN216082563 U can determine whether the high temperature resistance of the pipe meets the standard by detecting the size of the deformation of the pipe under high temperature environment, and it has a certain degree of accuracy.

[0003] However, most existing high-temperature resistance testing equipment uses the method described above, which involves placing the pipe in a liquid environment. As a result, after the test, the surface of the pipe is covered with liquid, and it is necessary to clean the liquid off the surface afterward. Secondly, the above-mentioned testing equipment uses a single detection probe, which can only test a certain location on the pipe. Such test results are bound to have a certain degree of uncertainty. If multiple locations need to be tested to ensure the accuracy of the test, the operation needs to be repeated several times, which increases the workload. Summary of the Invention

Detailed Implementation

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] As shown in Figures 1-2, this utility model provides a technical solution: a high-temperature deformation detection device for pipes, including a housing 1. The inner cavity of the housing 1 is provided with a partition 2. The partition 2 is made of copper sheet, or other metal materials with good thermal conductivity and hardness. Copper sheet has excellent thermal conductivity. The partition 2 divides the space inside the housing 1 into a heating chamber 3 and a detection chamber 4. The side wall of the heating chamber 3 is provided with an inlet 5 and an outlet 20. Heating liquid can be injected into the heating chamber 3 through the inlet 5.

[0025] The front of the housing 1 is equipped with an openable and closable sealing cover 21, which makes it easy to put in and take out the pipes after the sealing cover 21 is opened.

[0026] The heating chamber 3 is located on the periphery of the detection chamber 4. The high temperature inside the heating chamber 3 is transferred to the detection chamber 4 from the outside to the inside. A heating wire 18 is installed inside the heating chamber 3.

[0027] A support base 6 is provided at the bottom center of partition 2. It should be noted that there is one set of support bases at the front and one set at the back. The front and back sides of the pipe are supported on the support base 6, and the middle part (the inspection part) is suspended. The top of the support base 6 is provided with a concave groove that matches the pipe. The two sides of the support base 6 are provided with fixing bolts 19 for clamping the pipe. The bolts 19 can be adjusted for tightness.

[0028] Two sets of rotatable actuating rollers 22 are installed inside the support base 6. The actuating rollers 22 are driven by an external motor. Part of the actuating rollers 22 are exposed on the concave groove to actuate the tube and turn it over. The external motor can drive the actuating rollers 22 to rotate, thereby driving the tube to turn over, which facilitates the detection of different positions of the tube.

[0029] A temperature sensor 7 is installed on the top of the detection chamber 4 to detect the temperature inside the detection chamber 4.

[0030] The top of the housing 1 is provided with a support frame 8, on which a rotatable screw 9 is installed. The screw 9 is driven by an external motor 10. A liftable platform 11 is threaded onto the screw 9. The left and right sides of the platform 11 are slidably connected by slide rods. The slide rods and the platform 11 are triangularly distributed. A plug rod 12 is installed at the bottom of the platform 11. The bottom of the plug rod 12 is inserted into the detection chamber 4.

[0031] A ring frame 13 is installed at the bottom of the insertion rod 12. Multiple sets of cylinders 15 and pressure detection probes 14 are respectively installed on the ring frame 13. The cylinders 15 can drive the pressure detection probes 14 to press against the surface of the pipe. The pressure detection probes 14 can detect the slight deformation of the pipe. The pressure detection probes 14 are electrically connected to the pressure gauge 17 located on the platform 11 through the wiring harness 16.

[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0033] In use, first open the sealing cover 21, place the pipe to be tested on the support base 6, then tighten the outer wall of the pipe with the fixing bolts 19, and then close the sealing cover 21.

[0034] Then, the motor 10 is turned on, driving the screw 9 to rotate, which in turn drives the ring frame 13 to descend, and makes the pressure detection probe 14 press against the surface of the pipe (at this time, the pressure between the pressure detection probe 14 and the pipe is zero).

[0035] Heating liquid is added into the heating chamber 3 through the water inlet 5 and heated by the heating wire 18. During this process, the heat is quickly transferred to the detection chamber 4 through the partition 2 (metallic copper sheet or composite copper metal material or aluminum alloy material) until the detection chamber 4 reaches the target detection temperature.

[0036] The pipe will undergo a certain deformation at high temperature. The deformation pressure is detected simultaneously by multiple pressure detection probes 14 on its surface, and the relevant pressure value is read by pressure gauge 17 (deformation pressure detection is existing technology and will not be described in detail). The high temperature resistance index of the pipe can then be determined.

[0037] In summary, this high-temperature deformation detection device for pipes separates the heating liquid from the pipe by setting up a partition, and uses the high temperature of the heating liquid to keep the pipe in a closed and stable high-temperature environment. This ensures that the pipe can be tested smoothly while avoiding direct contact between the pipe and the heating liquid, saving unnecessary trouble. Furthermore, by setting up a structure with multiple pressure probes, multiple parts of the pipe can be covered at once, and the deformation of multiple parts of the pipe can be read at the same time. The test results are obtained through pressure gauges, making the test results more accurate.
