Description

Technical Field

[0001] This utility model relates to the field of ceramic tube pressure resistance testing technology, and in particular to a ceramic tube pressure resistance performance testing device. Background Technology

[0002] Pressure resistance testing of ceramic pipes is an important testing method to assess whether ceramic pipes can withstand certain pressures in practical applications. Ceramic pipes may be subjected to internal or external pressures during actual use. If the pressure resistance of the ceramic pipe is insufficient, it may rupture during use, leading to liquid leaks, gas leaks, or other hazardous situations. For example, in chemical pipelines, if a ceramic pipe ruptures, it may cause chemical leaks, resulting in environmental pollution or personal injury.

[0003] Currently, existing ceramic tube pressure resistance tests mainly include hydrostatic testing and pneumatic testing. Hydrostatic testing involves injecting high-pressure liquid (usually water) into the ceramic tube, gradually increasing the pressure, and observing the tube's performance under different pressures. Pneumatic testing involves introducing high-pressure gas into the ceramic tube to test its pressure resistance at a specific pressure. While relatively simple to operate, the testable pressure range is typically limited. For example, the Chinese utility model patents "CN203011776U, entitled 'A Testing Fixture for Ceramic Tube Pressure Resistance'" and "CN103123311A, entitled 'A Pressure Resistance Testing Device for Ceramic Tubes'" can only test blind-tube type ceramic tubes, are not easy to observe, and their protection is limited to a sheath, which is inadequate.

[0004] Therefore, there is an urgent need to develop a simple and reliable testing device for the pressure resistance performance of ceramic tubes. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this invention is to provide a device for testing the pressure resistance of ceramic tubes. The technical solution adopted by this invention is as follows:

[0006] A pressure resistance testing device for ceramic tubes is disclosed, which performs pressure resistance testing on straight-through ceramic tubes. The device includes a rear sealing end cap assembly and a front sealing end cap assembly with identical structures; an outer protective steel sleeve disposed between the rear and front sealing end cap assemblies; an observation window formed on the outer protective steel sleeve along its length; an acrylic transparent tube disposed between the rear and front sealing end cap assemblies and fitted within the outer protective steel sleeve; an inlet pipe connected to the front sealing end cap assembly; an exhaust pipe connected to the rear sealing end cap assembly; a normally closed valve on the exhaust pipe; and several connecting rods connecting the rear and front sealing end cap assemblies. The end of the acrylic transparent tube is sealed to both the rear and front sealing end cap assemblies. The end of the ceramic tube is connected to the inlet and exhaust pipes respectively. The inner sides of the rear and front sealing end cap assemblies and the acrylic transparent tube together form a release chamber. The ceramic tube is placed within the release chamber.

[0007] Furthermore, the front sealing end cap assembly includes an end cap that is pressed against the ends of the outer protective steel sleeve and the acrylic transparent tube, a ceramic tube mounting hole opened in the end cap and communicating with the air inlet pipe, an air pipe connection cap that is sealed to the end cap, a first sealing ring disposed between the end cap and the end of the acrylic transparent tube, and a second sealing ring disposed between the ceramic tube and the ceramic tube mounting hole; the end of the ceramic tube is placed in the ceramic tube mounting hole.

[0008] Furthermore, the air intake pipe and the air pipe connection cover are connected by an interference fit.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] (1) This utility model sets an outer protective steel sleeve and an acrylic transparent tube, and sets an observation window on the outer protective steel sleeve so that the situation inside the acrylic transparent tube can be observed through the observation window, which is intuitive and reliable.

[0011] (2) The present invention forms a release cavity in the rear sealing end cap assembly, the front sealing end cap assembly and the acrylic transparent tube. When the ceramic tube bursts, it is confined in the release cavity and reinforced by the outer protective steel sleeve to ensure more reliable protection.

[0012] (3) This utility model ensures the reliability of its installation by setting a rear sealing end cap assembly and a front sealing end cap assembly and sealing the ceramic tube.

[0013] In summary, this utility model has the advantages of simple structure and reliable testing, and has high practical and promotional value in the field of ceramic tube pressure resistance testing technology. Attached Figure Description
