are hollow rubber products used for flexible connection between metal pipes. It consists of inner and outer layers of rubber, ply and traveller, which form a tubular rubber piece. After vulcanization, it is combined with metal flange or parallel joint loose sleeve. Not only can it reduce vibration and noise, but it can also compensate for thermal expansion and contraction caused by temperature changes. It is widely used in various pipe systems.
One end of the flat rubber soft joint is
mounted on a flat flange with an exhaust valve, and the other end is mounted on a flat flange cover with an air cylinder, which is connected to the pressure outlet pipe, then fixed on the test bench and started Test the pump, flush water or other applicable media into the rubber joint to drain the air, close the exhaust valve, and stop the pump. Adjust the sample position and fix it, measure and record the initial length of the pattern.
Lateral displacement test of rubber joints: This test can be carried out separately or can be continued after the axial displacement test is completed and the sample is reset to the state specified in the test preparation. Turn the screw of the test bench, and push the flexible rubber joint laterally to the maximum allowable lateral displacement as specified in the specification and fix the position. According to the axial displacement test, the gauge pressure is increased to the specified pressure in the specification. The working pressure of the test product was maintained for 5 minutes, and the rubber soft joint samples were checked for leakage, cracking or abnormal deformation and recorded.
Axial displacement test of soft rubber joints: After the test preparation is completed according to the steps described in the test preparation, turn the test table screw to stretch or compress the rubber joint to the maximum allowable elongation or maximum allowable compression specified in the specification, Fix the position, increase the gauge pressure to the working pressure of the test product specified in the specification according to the boosting speed specified in the test preparation, hold the pressure for 5 minutes, check the sample for leakage, cracking or abnormal deformation and record it .
