How to adjust the anti-pull-off rubber joint

How to properly install anti-pull off rubber soft joints, when installing rubber joints anti-pull off limit device when the pipeline diameter is below DN300 and there is already a fixed bracket on the pipeline, you can not add a limit device, the pipeline is above DN300, the pipeline has a fixed bracket, and the pressure is too high, you need to add a limit device on the rubber joint, so as to increase the service life of rubber joints, but also to fundamentally solve the pipeline The problem of adjustment of expansion volume.
 
1 . Generally according to the application of engineering drawings to make up the amount of provisions, the overall adjustment of the upper nut, adjust the length of the rubber expansion joint, in order to achieve the necessary amount of compensation, twist the upper rubber joint nut, has a good sealing effect.
2 . Butterfly valve etc. with the application, according to its own two flange surface middle axial and radial angular velocity, perspective deviation, clear the pipeline thermal stress caused by the pipeline temperature difference, to the installation and maintenance of the pipeline produces a great convenience.
3 . In in the factory structure length for the minimum length, ground bolt for tight situation, installation to pull to the installation length, installation immediately after the ground bolt tightening .
4 . When used to connect, the rubber soft joint can be adjusted to the required length according to the specified amount. If used to compensate for pipeline deflection caused by temperature difference, the installation must be adjusted to the installation length at room temperature.
5 . Rubber flexible joints can be installed in any place in the pipeline, but they should be located behind the valve when used for connection.
6 . The pipeline with long pressure should be set in the rubber support around the rubber joint, and the foot bolt should be tightened immediately after installation, paying attention to the level of tightness and looseness, which should be adjusted according to the pressure of the pipeline, too tight or too loose will jeopardize the actual effect of sealing and sex, operational flexibility, and at the same time, the positioning foot bolt should be fixed and immobile immediately to avoid pulling off during application.
7 . Seal ring is the important of rubber soft joint goods to complete the sealing, adjust the positioning foot bolt situation must be solved with care, to avoid pressure squeeze too much and rupture condition.
