With the rapid development of modern scale, a single practical automotive steering parts rubber soft joint can no longer meet the requirements of the actual installation of the natural environment. A new type of compression rubber soft connector. Contrasted with traditional rubber soft joints, it has structural and material qualities. Some adjustments have been made to the above, and the most significant one is to increase the contact area of the two internal threads of the pressure rubber soft connector, which can improve the closed feature of the product and the middle of the pipeline. Secondly, the thickness of the anti-pressure rubber soft joint also increases the moderateness, so that the total pressure of the product can be increased to a certain extent.

The difference between the compression rubber soft joint and other practical rubber soft joints is that its sphere is thin and thick, the external positioning equipment is improved, the convex surfaces on both sides of the sphere are enlarged, and the connecting flanges are of tensile strength. Carbon steel or stainless steel plate. According to such structural changes, the compression resistance range of the rubber soft joint is increased. Small size, relatively light weight, good ductility, convenient and quick installation and maintenance. During installation, it can cause tangential, horizontal, weft, and angular deviation, and will not suffer from the customer's pipeline blockage and non-parallel flanges. When working, it can reduce the transmission noise of the structure and has strong vibration absorption ability.
I often receive relevant consumer inquiries about the pressure test of rubber soft joints. Based on many years of experiments, I have summarized the following aspects to pay attention to. I hope it can be of help to everyone. The rubber soft joint can be used as a flexible joint for the flexible joint of the pipeline master plan. When the pressure test of the rubber soft joint is stopped, pay attention to the following aspects: specify the test pressure of the plastic soft joint according to the pipeline regulations, and exhaust the gas when adding water before the test. The operating temperature of the rubber soft joint should not be lower than 5°C under the experimental conditions. When the operating temperature is lower than 5°C, the antifreeze method should be adopted.
When the rubber soft joint and the mechanical equipment are subjected to a management system termination test, and the test pressure of the rubber soft joint is equal to or less than the experimental pressure of the mechanical equipment, the test shall be stopped according to the experimental pressure of the plastic soft joint; when the plastic soft joint test pressure exceeds 3 When the experimental pressure of the mechanical equipment is not lower than 1.15 times the pressure of the construction drawing, the experiment can be stopped according to the experimental pressure of the mechanical equipment with the approval of the establishment enterprise. The experimental pressure of the rubber soft connector is slowed by the DC transformer. After reaching the experimental pressure, the regulator tube is used for 10 minutes, and then the experimental air pressure is brought to the overall design pressure. Stop the pressure for 30 minutes, and the working pressure does not drop and there is no water leakage as qualified.
