What system does the pneumatic wear-resistant ventilation butterfly valve jump when it is opened? After you make us understand such a truth, we believe that we always know how to do such things. After all, we know that with the development of society, many people know that society has been developing at a high speed. If we are still backward in science and technology, we believe that we must be backward in economy, If we think that we can eliminate some manual devices and directly bump them into electric devices or electric transmission devices, then many people believe that pneumatic butterfly valves are really easy to use. This is the result of their various comparisons, It is not very impulsive to make a subjective opinion, but after careful examination.
、 Third, due to the eccentric structure, the sealing between the sealing surface of the valve plate and the valve seat mainly relies on the torque of the transmission device to press the valve plate against the valve seat. If it is in the positive flow state, the medium pressure is very high, and the seal extrusion will also be very tight. When the reverse flow occurs, the medium pressure increases, and the unit positive pressure between the valve plate and the valve seat will be smaller than the medium pressure, thus sealing leakage will occur.
