How to install the rubber flexible joint in the pipeline without water leakage
In such a rapidly developing society, various pipelines under the road had begun to be unable to accept the vibration brought by various vehicles on the road, and not only these, so a product called rubber flexible joint was invented. Its function is to make the compensation of long spacing pipes connected, with the characteristics of displacement compensation, vibration reduction and noise reduction, similar to that of rubber shock absorber.
Rubber flexible joints are commonly used in drainage pipes, seawater desalination pipes, ship pipes, fire protection pipes, sewage disposal pipes, etc. These alone illustrate that the rubber flexible joint must have the characteristics of corrosion resistance, upper and lower temperature resistance, and friction resistance to make the pipeline run safely for a long time.
How can the rubber flexible joint be installed to ensure no water leakage in the pipeline? First of all, we must know why it leaks and where the device is bad. The rubber joint products generally adopt flange connection. During the flange connection process, the protruding rubber edge of the rubber end face of the rubber joint itself shall be used as the sealing information to seal the flange end face of the rubber joint. Therefore, the rubber joint in the buckle groove is prone to water leakage, while the fully sealed rubber joint on the end face will not, The main reason is that the grooved rubber joint device does not well clip the rubber sealing end face into the groove of the flange, so that the rubber joint is prone to suffer from partial pressure concentration at the edge and leakage during the use. The correct device is as follows:
1. During the installation of the rubber shrink joint, the rubber part must be well buckled into the flange groove;
2. Do not tighten the bolt too hard. Since tightening the bolt will crush the sealing surface at the rubber edge, the sealing surface will be broken, and the rubber ball will be scrapped locally. If this situation occurs, loosen it a little.

What is the general pneumatic butterfly valve
What is the difference between general pneumatic butterfly valve and ordinary pneumatic butterfly valve? Universal pneumatic butterfly valve is an important connecting component in engineering technology, which is composed of stainless steel corrugated flexible pipe wrapped with braided mesh sleeve and two end joints. The advantages of the universal pneumatic butterfly valve are that the device is convenient and fast, one model can be used in many categories, and the application is universal.
