Introduction: Flexible rubber flexible joint is a flexible coupling of metal pipes. It has the characteristics of good elasticity, large displacement, high compression resistance, vibration absorption and noise reduction. It is widely used in machinery, circulating water, HVAC, fire protection, paper industry, pharmaceutical industry, petrochemical equipment, etc

Flexibility Rubber flexible joint It is a flexible coupling for metal pipes. It has the characteristics of good elasticity, large displacement, high compression resistance, vibration absorption and noise reduction. It is widely used, such as mechanical, circulating water, HVAC, fire protection, paper industry, pharmaceutical industry, petrochemical equipment and other piping systems. Next, the relevant information of flexible rubber flexible joints is sorted out to help you master the flexibility Installation and principle of rubber flexible joint.
I. installation method of flexible rubber flexible joint
1. During the installation of flexible rubber flexible joint, it is forbidden to install it with excessive displacement.
2. Horizontal, suspended and vertical installation above 1.0MPa on the ground Rubber joint There should be fixed supports or fixed trailers on both sides of the pipeline to prevent breaking or damaging the equipment.
3. The fixed support or fixed force must exceed the axial force of the work, otherwise, anti pulling equipment should be installed.
4. The flange corresponding to the installation of flexible rubber joint shall be provided with corresponding standard flange for rubber joint, so as to prevent the flange D2 and do from being too narrow and water seepage on the protruding surface.
5. Flange bolts of flexible rubber joint shall be symmetrically and gradually pressurized and tightened to prevent partial leakage or damage of protruding surface of flexible rubber joint when bearing force.
6. When the working pressure is more than 1.0MPa, the rubber joint shall be installed horizontally, suspended in the air and vertically, and the installation bolt shall be provided with elastic cushion to prevent the bolt from loosening and causing partial water seepage and leakage.
7. When installing the flexible rubber flexible joint, it is necessary to have a support frame, and the flexible rubber joint is not under pressure.
2. Planning principle of flexible rubber flexible joint
1. The aperture size of flexible rubber flexible joint should be consistent with the screw diameter of extruder. Because of the large aperture of the die, the pressure of the die is not enough, and then the die force is different. The appearance of the semi-finished product is not neat, the density of the flexible joint compound is small, and the aperture of the die is very small, which will cause the rubber material of the flexible joint to stagnate for a long time in the die head and cause scorch.
2. In general, when extruding semi-finished products with solid or circular cross-section, the hole diameter of the die should be 1 / 3-3 / 4 of the screw diameter. When extruding flat semi-finished products, because the cross-section is thin, so as to give full play to the equipment potential, the total extrusion width of tread is generally equal to 2.5-3.5 times of the screw diameter.
3. A certain cone angle should be designed for the mouth shape of flexible joint, that is, the diameter of the inner end of the die is large, and the diameter of the end close to the rubber outlet is small. The design of the cone angle of the mouth shape is beneficial to the fluidity of the rubber compound and prevent the blind area.
4. In general, the establishment of the cone angle of the die is based on the die size and the characteristics of the extrusion compound. The higher the cone angle is, the higher the extrusion pressure is and the faster the extrusion rate is. The surface of semi-finished products is smooth and compact, but the extrusion deformation is also greater.
5. The inner cavity of the die should be smooth and smooth, with flow line shape, without vortex, so as to make the fluidity rate of flexible rubber soft joint compound in all fluidity directions tend to be consistent as far as possible.
