The invention discloses an automotive brake rubber hose pressure resistance test platform with a pressure relief part. The test platform comprises a control tank and a test tank. The outer side of theupper shell of the test tank is connected to the pressure relief part. The pressure relief part comprises a tubular protective shell. An upper cover is arranged above the protective shell. The uppercover is connected to the upper shell through two springs. The upper shell in the protective shell is provided with vent holes. The lower end of an anti-dropping column is fixedly connected to the upper shell. The upper end of the anti-dropping column passes through the upper cover. The part, passing through the upper cover, of the anti-dropping column is provided with a linear bearing and the upper end of the anti-dropping column is provided with an end block of which the diameter is greater than that of the anti-dropping column. In use, when the pressure in the test tank is too high, the upper cover can be injected and opened under pressure so that the pressure is released through open cracks. Through use of the anti-dropping column, the upper cover does not fall off, the use safety of the device is effectively guaranteed, the use needs of customers are satisfied and the test platform is easy to promote and use in the industry.
Description
technical field [0001] The invention relates to the technical field of automobile testing, in particular to a pressure-resistant test platform for brake rubber hoses for automobiles with a pressure relief part. Background technique [0002] Rubber hoses are widely used in automobiles, and are used in air brake systems, oil brake systems, cooling systems, lubrication systems, and tire inflation, with various varieties and specifications. Brake hoses for automobiles are used to transmit pressure in automobile braking systems. They are divided into hydraulic brakes and pneumatic brakes (air pressure hoses belong to low-pressure hoses, and hydraulic hoses belong to high-pressure hoses). During the production process of hydraulic brake hoses In the process, it is necessary to carry out a pressure test and a burst test on the hydraulic brake hose to check whether it is qualified. Usually the pressure test pressure of the hydraulic brake pipe is 20MPa, and the burst pressure is 35...
