Technical Field

[0002] Silicon carbide ceramics, with their excellent properties such as high temperature resistance, corrosion resistance, high thermal conductivity, and high strength, have become a new generation of heat exchange materials. Silicon carbide ceramic heat exchange block orifice components adopt a deep-hole structure with indirect wall construction, offering a large heat exchange area, high pressure resistance, and resistance to water hammer impact. They are highly suitable for environments with high pressure, thermal shock, corrosion, and particle erosion, and have broad application prospects in chemical and metallurgical fields such as chemical acid bath flash evaporation, stainless steel pickling, and fluorochemicals. Pressure testing is required for silicon carbide ceramic block orifices to prevent leakage during use and ensure safety.

[0020] The following detailed description of preferred embodiments of the present invention, along with the included examples, will make the content of the present invention more readily understood. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. In case of any conflict, the definitions in this specification shall prevail.

[0021] Example 1:

[0022] Provided such as Figure 1The device shown is a silicon carbide block hole water pressure testing device, which includes a first fixed seat 1 and a second fixed seat 2. The first fixed seat 1 and the second fixed seat 2 are fixedly connected by a connecting rod 3. A clamping space is formed between the first fixed seat 1 and the second fixed seat 2. The clamping space is used to clamp the silicon carbide block 4. A water pressure chamber is formed between the first fixed seat 1 and the silicon carbide block 4.

[0023] The water pressure chamber includes an injection hole 11, a drain hole 12, and a water flow channel 13. The water flow channel 13 is located at the bottom of the first fixed base 1. The injection hole 11 and the drain hole 12 pass through the first fixed base 1 and communicate with the water flow channel 13. A plug is installed inside the drain hole 12. The injection hole 11 is connected to an external water pressure machine, which has a water pressure detector that can display the water pressure of the water medium injected into the water flow channel 13 from the injection hole 11. The plug can be made of rubber and is inserted into the drain hole 12 to control the opening and closing of the drain hole 12.

[0024] The bottom of the first fixing seat 1 is provided with a first groove 14, which surrounds the water flow channel 13. A first sealing ring 15 is provided inside the first groove 14. The first sealing ring 15 is used to seal between the silicon carbide block 4 and the first fixing seat 1.

[0025] The top of the second fixing seat 2 is provided with a second groove 21. A second sealing ring 22 is provided in the second groove 21. The second sealing ring 22 is used to seal between the silicon carbide block 4 and the second fixing seat 2.

[0026] One end of the connecting rod 3 is fixedly connected to a bolt head 31. The connecting rod 3 passes through the first fixed seat 1, and one end of the connecting rod 3 is fixedly connected to the second fixed seat 2 by threads. The first fixed seat 1 slides on the connecting rod 3, and the bolt head 31 presses the first fixed seat 1 tightly onto the silicon carbide block 4, increasing the clamping force.

[0027] There are four connecting rods 3, which are distributed at the four corners of the second fixed seat 2.

[0028] Working principle: First, open the drain hole 12 and connect the water injection hole 11 to the water pressure tester. The water medium enters the water flow channel 13 through the water injection hole 11 and then enters the silicon carbide block 4, simulating actual working conditions. When you see that the drain hole 12 has started to drain, close the drain hole 12 and observe whether the pressure parameters of the pressure tester have reached the testing conditions. Increase the water injection pressure to the set pressure threshold and observe the product status. If water seeps out from the outer end of the product, it indicates that there are cracks inside the heat exchange block and poor sealing.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
