Hard -sealing butterfly valve is also called turning valve. It is a simple regulatory valve, and can also be used for switch control of low -voltage pipeline medium.Hard -sealed butterfly valve mainly plays a role of cutting and throwing on the pipeline.
Discarded butterfly valve leaks water
How to deal with the leakage of the hard -sealed butterfly valve: grouting and embedded method: Pickle out the filling in the original deformation seam, clean it to the surface of the water -stop belt, and rinse it., Do not fill it up in order to leave room for the embedded seam. After a certain distance, a grouting mouth is buried at a certain distance. After the rapid condensate material reaches a certain intensity, you can pour the elastic slurry of the mouth by grouting the mouth pressure.No more water.Then fill the upper part of the deformation seam groove that has stopped, fill the same expansion rubber bar or elastic sealing material as width as the seam width.
Hard -sealed butterfly valve model
The model of the hard -dermis butterfly valve is divided into structural form: (1) Central sealing butterfly valve (2) Single eccentric sealing butterfly valve (3) Double -eccentric sealing butterfly valve (4) Three -e -sealing butterfly valve sealing material points: (1) Soft seal butterfly valve.1) The seal is composed of non -metallic soft materials on non -metal soft materials.2) The sealing sideline consists of metal hard materials for non -metal soft materials.(2) Metal dilute butterfly valve.The seal is composed of metal hard materials for metal hard materials.
