How to install the soft valve 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 soft valve was invented. Its function is to make the compensation of long interval pipes connected, with the characteristics of displacement compensation, vibration reduction and noise reduction, similar to that of electric butterfly valves.
Soft valves are commonly used in drainage pipes, seawater desalination pipes, ship pipes, fire fighting pipes, sewage disposal pipes, etc. These alone illustrate that the soft valve 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 soft valve 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 valve products generally adopt flange connection. During the flange connection process, the protruding edge of the valve end face shall be used as the sealing data to seal the valve flange end face. Therefore, the common grooved valves are prone to water leakage, while the fully sealed valves on the end face will not, The main reason is that the grooved valve device does not well snap the sealing end face into the groove of the flange, so that the valve is prone to have partial pressure concentrated at the edge and leakage during the operation. The correct device is as follows:
1. In the process of shrinking the valve device, the glue must be buckled into the flange groove;
2. Do not tighten the bolt too hard. Since tightening the bolt with all the force will crush the sealing surface at the edge, the sealing surface will be broken, and the sphere will be scrapped locally. If this situation occurs, loosen it a little.
