Description

Technical Field

[0001] This utility model belongs to the field of rubber hose testing technology, specifically relating to a rubber hose sealing performance testing device. Background Technology

[0002] Rubber hoses are pipes used for gas transportation, commonly used in gas welding, gas cutting, various gas shielded welding, plasma arc welding, and cutting. Rubber hoses possess properties such as physiological inertness, UV resistance, ozone resistance, high and low temperature resistance, high transparency, strong resilience, permanent compression resistance without deformation, oil resistance, impact resistance, acid and alkali resistance, wear resistance, flame retardancy, voltage resistance, and electrical conductivity. Depending on the installation location, the working pressure varies from 0.1 MPa to 10 MPa. Rubber hoses undergo airtightness testing before leaving the factory.

[0003] A search revealed a Chinese utility model patent application (CN213874839U) disclosing an airtightness testing device for rubber hose connections. This device includes a testing water tank. A support frame is fixedly connected to the upper surface of the water tank, and an electric push rod is fixedly connected to the lower surface of the support frame. A positioning frame is fixedly connected to the end of the electric push rod furthest from the support frame. When airtightness testing of a rubber hose is required, both ends of the hose are connected to an air inlet and a positioning tube, respectively. An air pump is then activated to inflate the hose. The electric push rod is then activated to insert the hose into the testing water tank. By detecting where air bubbles emerge from within the tank, the presence of leaks in the rubber hose can be quickly determined.

[0004] Regarding the aforementioned technologies, the sealing performance of the air inlet and the sealing port of the rubber hose is crucial when conducting tests. Relying on springs and rubber gaskets for sealing results in poor sealing at both ends of the rubber hose, which can easily lead to leakage and affect the accuracy of the test. Therefore, there is an urgent need to design a rubber hose sealing performance testing device to address these issues. Utility Model Content

The temperature detector 306 monitors the temperature inside the chamber 201, and the air pressure monitor 308 monitors the air pressure inside the chamber 201 to ensure it remains at a normal level. The valve 205 is then closed to prevent backflow of gas into the hose body 410 and the air bladder 209. If there are gaps on the surface, airflow will occur on the surface of the hose body 410, which is monitored by the airflow monitor 308, thus completing the rubber hose sealing test.
