They are widely used by users. However, the department butterfly valve has a significant defect. When it has been used for a long time. Due to rubber aging and other reasons, it is easy to cause the butterfly valve to close tightly. It is not suitable for the occasions with strict switch requirements.
There are many factors that cause the water pipeline butterfly valve to close tightly. The core problem is that the sealing seat of the butterfly valve is damaged. This may be an objective reason. For example, the rubber has been used for a long time, the valve plate has been squeezed and aged, and the seal has lost its elasticity. It is not strict, and if it is a sewage pipe, some impurities in the sewage are stuck on the sealing surface, which will also affect the rubber seal to a certain extent, especially large particles.
From the subjective factors, if the pressure difference between the front and back of the butterfly valve Larger, it will also cause the butterfly valve to close tightly, and the pressure difference will create a certain resistance, which will make the valve plate switch in place, will also impact the rubber valve seat, reducing its life. In this case, a certain pressure regulating device must be installed behind the valve. Adjust it in time to make the pressure drop down as much as possible, and the switch will be smooth.
